The Origins of Colonial Investmentsin Former British and French Africa*

Abstract
Recent literature has documented the economic and political consequences of colonialism,
but we have little systematic evidence about the origins of colonial investments despite their
long-term impact. Combining multiple data sources, I present evidence that they were very
unequally distributed across the districts of 16 British and French African colonies. How did
colonial states allocate their investments? Some focus on ethnic disparities in colonial treat-
ment, following a divide and rule logic, while others emphasize the role of natural resources.
I argue that observable geographic features led some places to become centers of pre-colonial
coastal trade, which increased later colonial investments not only in infrastructure but also
in health and education. Although the context was highly extractive, pre-colonial commerce
also helps explain the limited diffusion of investments within each colony. A de facto de-
centralized colonial state and European settlement are two of the mechanisms behind the
persistence of inequality over time.

1 Introduction
The last two decades have seen a surge in the literature examining the economic and political
consequences of colonialism, notably in Africa, the Americas and South Asia.1 Existing claims
about the effects of colonial institutions, investments and practices are wide-ranging.2 Some of this
literature uses instances of arbitrary or “as-if” random variation in a particular aspect of colonial
rule to identify those consequences, such as spatial discontinuities in agricultural revenue collection
systems in India (Banerjee and Iyer, 2005), in extractive forced labor in Peru (Dell, 2010), or in
missionary school location in Benin (Wantchekon, Novta and Klasnja, 2015). However, colonial
investments are likely not random beyond some particular instances. Explaining their origins
is important because they fundamentally affected welfare and development during colonial rule
as well as contemporary economic development (Huillery, 2009). Yet, we know little about the
quantitative distribution of colonial investments and about the causes underlying their distribution.
Combining multiple original and existing data sources, I present systematic evidence that
colonial investments were very unequally distributed across and within 16 British and French
colonies in East and West Africa.3 This paper focuses on the large within-colony variation in
investments across colonial districts. This focus allows us to hold institutions constant, since in
East and West Africa they varied little within each colony. Investments in some districts were orders
of magnitude larger than in others in the same colony, also when taking population into account
(Figure 1). These district inequalities exist for the three main types of investments—education,
infrastructure and health—in both empires (Figures 4-6, p. 17) and they do not diminish during
the colonial period.
Why did Europeans invest much more in some districts than others? The most immediate ex-
planation concerns a divide and rule logic, whereby the European colonizer discriminated between
ethnic groups to prevent coordinated opposition to imperial rule. Existing literature provides

Note: The graphs show the distribution of investments by district in two former colonies. The left graphs showthe raw number of public health staff (doctors and nurses) and students per colonial district while the right graphsadjust that number per 100,000 people. While the order of districts in the right graphs somewhat changes, inequalityremains remarkably similar.
qualitative and historical evidence that treatment was indeed unequal across groups and regions,
but the causes underlying this inequality remain unclear. Horowitz (1985) termed this inequality
the “ethnic distribution of colonial opportunity”: some groups and regions benefited more from,
or were less harmed by, colonialism than others. For instance, in 1960 “the Kakwa and Lugbara
[in Northwestern Uganda] had between them a single student enrolled in Makerere University”,
the first university in East Africa. “The Baganda [in Central Uganda], though only 16 percent
of the population, comprised nearly half” of the student body (Horowitz, 1985, p. 151, p. 239).
Investments were also unequal in other domains of the British and French colonial state, notably
3
economic activity (Cooper, 1996) and colonial army recruitment.4 It is less clear whether a par-
ticular ethnic or local characteristic can explain these inequalities systematically.
Recent research has shown that higher levels of pre-colonial political centralization across eth-
nic groups, a highly visible characteristic that can be used to divide and rule, improve current
socioeconomic outcomes.5 For instance, the British found it convenient to co-opt the existing
social structure of the the Buganda Kingdom and invested more in that region than elsewhere in
Uganda. However, there are opposite examples as well: because the Hausa States in Northern
Nigeria were more politically developed than the rest of the colony, Lugard (1922) decided they
should be ruled indirectly and hence received lower investments. I find that colonial district in-
vestments were not affected by pre-colonial kingdoms and I find little support for other possible
explanations, such as pre-colonial ethnic diversity and fragmentation (Alesina, Baqir and Easterly,
1999; Easterly and Levine, 1997) lowering investments across districts. Divide and rule was an
important ruling strategy, but it may have been context-specific rather than systematically relying
on some ethnic or regional characteristic.
I argue instead that focusing on the economic logic of colonialism allows us to better understand
variation in infrastructure, education and health investments. European colonialism was first and
foremost an exploitative enterprise with economic profit as one of its main motivations (Young,
1994; Suret-Canale, 1971; Darwin, 2012; Diamond, 2005), and natural resources were central to
the colonial enterprise. Curtin et al. (1995, p. 447) explains that “European capital was invested
where exploitable resources promised the most extractive returns” (Huillery, 2010, p. 271). For
instance, the British took control of Ghanaian gold and Sierra Leonean diamonds because they
enjoyed a first-mover advantage over the French.6 Wantchekon and Stanig (2015, p.5) show that
4The King’s African Rifles in British Kenya provide one example: “lacking the education and financial opportu-nities of their more fortunate Kikuyu neighbors, Kamba soldiers found kazi ya bunduki [military service] appealingbecause it was lucrative” (Parsons, 1999, p. 57). And while the French mission civilisatrice was in theory blind toracial or regional considerations, the conscription “system in French West Africa was biased against the rural, lessprivileged groups” (Sharkey, 2013, p. 156).
5Effects of pre-colonial political centralization on current outcomes include “light density at night, paved roads,immunization, literacy and infant mortality rates” (Bandyopadhyay and Green, 2016, p. 471; see also Michalopoulosand Papaioannou, 2013). These findings are consistent with Diamond’s (2012) claim that “the most important factorbehind [good institutions] is the historical duration of centralized government.”
6“With a great sense of the practical, the British had for a long time been snapping up the best coastal sectors.[...] Britain took possession of the territories with the richest resources and best future, although without any
4
“colonial infrastructure can be predicted [...] by the presence of extractive resources (mines and
quarries) but not by soil quality.” Using novel historical data, I also find that infrastructure is
predicted by natural resources. However, the effect is modest and does not spill over into education
or health investments, which served less extractive purposes.
The main reason why colonial administrators invested so much more in some districts than
others lies in the role played by pre-colonial coastal trade. Early commerce provides a common
origin to later investments in infrastructure, education and health in both empires, a finding
consistent with accounts of historical trade in the Indian and Atlantic oceans (Hourani, 1995,
p. 83; Curtin et al., 1995). Besides providing quantitative support for existing historical work, I
identify the causal effect of coastal trade by using natural harbors and capes as an instrumental
variable.7 Early explorers and traders in the Age of Sail possessed very limited information about
the territory (Foster, 1967), so locational fundamentals (Davis and Weinstein, 2002) such as natural
harbors and capes influenced where they landed and therefore the location of initial trading posts
between the 16th century and the 19th century—the period of slavery and the Triangle trade.8
This trade, of which slavery was an important component (Nunn, 2008), in turn explains later
colonial settlement and investments.9
The relevance of pre-colonial commerce is not restricted to these early coastal “development
hubs”: geodesic distance from early trading centers helps explain the limited diffusion of invest-
ments from these early enclaves to the rest of the colony. As Bates (1974, p. 464) put it, “originating
in ‘nodes’ or ‘central places’, modernity then spreads or ‘diffuses’ into the more remote regions
of the territory.” This diffusion is very limited because colonialism in most of East and West
Africa was short-lived and shallow compared to other regions such as South Asia, where existing
geographical ties: the Niger delta, basis of future Nigeria; the Gambia estuary, Sierra Leone and the Gold Coast”(Chi-Bonnardel, 1973, p. 50).
7Jha (2012) first used natural harbors as an instrument in South Asia. Capes (e.g. Dakar) are also a reasonablepredictor of trading posts in Africa, which has many fewer natural harbors (e.g. Mombasa).
8Europeans sold manufactured goods to Africa in exchange for slaves that were sold in the Americas. TheAmericas, in turn, provided cotton, sugar and other primary commodities to Europe.
9For most of East and West Africa, “pre-colonial” refers to the period starting in the 1500s up to the 1885 BerlinConference and “colonial” refers roughly to the period between 1885 and 1960.
5
research shows that trading companies were central and had a long-lasting influence on economic
development and interethnic tolerance (Jha, 2012; Gaikwad, 2014).10
The autonomy of local colonial administrators and European settlers are two important reasons
why pre-colonial trading areas received much higher colonial investments. First, the lack of a
central planner, and hence the high autonomy of administrators in an effectively decentralized
state, meant that redistributive or long-term strategic investments (e.g. the Uganda Railway)
to develop the periphery were the exception rather than the norm. Second, Europeans settled
in the few districts with basic infrastructure already in place and sometimes acted as a lobby
with interests in trade and agriculture (Gardner, 2012), likely contributing to regional economic
inequality. European settlers are hardly a root cause for variation in investments or institutions
(Acemoglu, Johnson and Robinson, 2001) but a mechanism to explain the persistent inequality
in investments. They only came to East and West Africa in any significant numbers in the 20th
century, 400 years after the Triangle trade had begun. Unlike in neo-Europes and many Spanish
American colonies, there were fewer than 10,000 settlers prior to 1940 in all 16 colonies under
study except for Kenya.11
Given a de facto decentralized colonial state and the spatial concentration of settlers, the early
advantages of pre-colonial trading centers persisted into the colonial period: they became centers
of economic activity that benefited from complementarities between investments in infrastructure,
education and health. The pattern is consistent with a logic of increasing returns (Krugman,
1991b, Pierson, 2000) and with urban agglomeration economies (Krugman, 1991a; Rosenthal and
Strange, 2004), albeit in a very different context: instead of firms in a private market, the agents
are colonial state administrators allocating public finances.
In sum, this paper makes three contributions. First, I show that pre-colonial commerce played
a central role for subsequent colonial development even in the very exploitative context of East
and West Africa, where slaves were a central export and commerce was much less developed than
10The British East India Company lasted almost three centuries while the British Royal Africa Company lastedonly one. French chartered companies in Africa such as the French West India Company or the Senegal Companywere not prominent or long-lasting either.

in India (Jha, 2012; Gaikwad, 2014) or China (Jia, 2014). Investment diffusion within a colony
is also in part the result of early trade, suggesting that its importance extends beyond the first
trading hubs in each colony. Second, I build upon the literature in ethnic politics and economic
history. The former provides ample case study evidence of the differences in opportunities and
exploitation across regions and ethnic groups, in line with a logic of divide and conquer, while
the latter highlights the commercial motivation behind European imperialism. I argue that the
root cause for these differences is economic. Finally, I contribute a dataset with new sources on
colonial investments—which allow me to quantify spatial inequality—, historical natural resources
and geographic subnational data spanning colonies of two empires.
2 Locational fundamentals and pre-colonial trade
“It is not an exaggeration that between 1550 and 1800 Europeans learned virtually
nothing new about the lands beyond the African coastline. [...] By 1875, in fact,
European possessions in Africa still only comprised the coastal forts and trading
stations and a few tiny colonies.”
Foster (1967, p. 45, 51)
Locational fundamentals are observable geographic characteristics of a territory that “change
little over time—even if their economic meaning may have evolved. For example, there are ad-
vantages of being near a river [or] on the coast, on a plain instead of a mountain or desert, etc.”
(Davis and Weinstein, 2002, p. 1270). Locational fundamentals are important to understand early
spatial patterns of economic activity in pre-industrial contexts, where geography greatly affects
mobility and economic activity (Diamond, 2005).
Early European exploration and commerce in Africa was difficult partly because much of the
Western and Eastern coastline did not possess geographic features amenable to docking ships.
For instance, much of the Windward and Gold Coasts in present-day Cote d’Ivoire and Ghana are
comprised of shallow waters (Curtin et al., 1995). Given the absence of man-made docks, Europeans
landed where coastal geography was favorable. Europeans observed variation mostly in geographic
7
characteristics because knowledge about socioeconomic and other characteristics of the territory
was very limited until the 19th century (Foster, 1967; Chi-Bonnardel, 1973). Geography was
especially important during the Age of Sail (1500s-1800s), when navigation technology depended
much more on environmental factors and wind patterns than in the later Age of Steam (1800s-)
(Feyrer and Sacerdote, 2009). Hence, the few natural harbors and capes (locational fundamentals)
that existed were valuable to Europeans engaged in the trade, including the shipment of slaves
since the 1600s (Figure 2).12

Note: Dates are approximate. Pre-colonial trade and colonization periods vary between colonies.
For instance, the Portuguese and later the French first landed in three places as they descended
through the Northwest African coast. One was Ras Nouadhibou (Cap Blanc), currently in the
border between Western Sahara and Mauritania. They also established trade in what would later
become the cities of Saint Louis and Dakar in Senegal because the former is a natural harbor
formed by the Senegal river mouth and the latter is in a cape (Cap-Vert).
Other factors influenced the location of trade during early exploration, such as the presence of
natural resources in the few areas that had long extracted them. The most famous cases in the
colonies under study are the diamond mines of Sierra Leone and the Gold Coast (current Ghana),
where the British disrupted a Trans-Saharan gold trade that had existed for centuries (Young, 1994,
p. 134). Even then we can see some geographic logic: two key locations where the British landed
were the natural harbor of Tagrin Bay in Freetown and Cape Coast in Ghana, a country without
natural harbors. East Africa has a longer history of navigation than West Africa because of Arab
explorations of the Indian Ocean and the Arab slave trade (Hourani, 1995, p. 83). However, an
12Young (1994, p. 103) provides a brief discussion of chartered companies in Africa and their relation to thecolonial state.
8
equivalent logic applies. Mombasa, a natural harbor, and Zanzibar, an island, became centers of
Arab-African trade centuries before the Europeans arrived in the 1500s. Horowitz (1985, p. 151)
suggests a similar logic to explain interactions between European colonizers and local populations
in the early colonial period in Africa and Asia: “groups located near the colonial capital, near a rail
line or port, or near some center of colonial commerce—the sitting of which was usually determined
by capricious factors, such as a harbor or a natural resource to be exploited—were well situated to
take up opportunities as they arose.” In sum, locational fundamentals led to differences between
certain areas in West and East Africa, which became engaged in Atlantic and Indian commerce,
and the rest of the territory.
2.1 Early trade and colonial investments
Proximity to trading centers became perhaps even more advantageous during the colonial period.
As Europeans increased effective control of the colonies in the early 20th century, trading posts
became central points for the international shipment of goods produced elsewhere in the colony,
strengthening linkages to the international economy, as Laitin (1982) explains for the case of
Western Nigeria. Lagos and other early commercial centers such as Abidjan and Freetown became
the colonial capitals, adding a political dimension to their economic preeminence within the colony.
Capitals were rarely chosen for their central geographic location within the colony, as it became the
case in independent Nigeria (Abuja) and Cote d’Ivoire (Yamoussoukro). For one thing, colonial
state borders were not even defined by the time the capital was chosen. While economic activity
spread, its persistent concentration in a few places in each colony had spillover effects on other
colonial investments, notably hospitals and schools such as the Ecole William Ponty in Goree
(Senegal) and Fourah Bay College in Freetown (Sierra Leone). In other words, investments in
education and health partly followed basic infrastructure investments. It was cheaper for colonial
officials to establish facilities such as schools and hospitals in places where basic infrastructure was
already in place and hence where initial costs were lower.
9
Similar patterns of concentration and persistence of economic activity have been theorized
elsewhere, originally in Krugman’s (1991b) application of increasing returns theory to economic
geography. 13 Similarly, each colony had a few districts with basic infrastructure—the industrial
core—while the majority was part of a periphery that was largely agricultural, pastoral or nomadic
and where colonial state reach was very limited (Herbst, 2000; Jackson and Rosberg, 1982). Be-
cause parts of the hinterland were not well-known even after colonial borders were defined, initial
costs of investment in a new location, including transportation costs, were compounded by un-
certainty about the future profitability of investments. An increasing returns logic, compounded
with a financially poor colonial administration that could not afford risky investments of uncer-
tain profitability, are two reasons why we should observe persistence in the spatial distribution of
economic activity during the colonial period. These two reasons also suggest that new investments
elsewhere in the colony might be a function of proximity to early commercial centers: all else equal,
investments in less remote areas are less costly and less uncertain.
3 Colonial state: structure and administration
The ‘command and control’ of this [British] empire was always ramshackle and
quite often chaotic. To suppose that an order uttered in London was obeyed round
the world by zealous proconsuls is an historical fantasy (although a popular one).
Darwin (2012, p. xii)
This section dispels the popular conception of the colonial state as a highly organized entity
with a central planner following clear investment rules. In reality, the colonial state in East
and West Africa was decentralized and district administrators often acted autonomously in both
empires. Decentralization and autonomy arguably favored the persistence of pre-colonial patterns
of economic activity into the colonial period. Since these claims are context-specific, I first explain
why decision-making was not centralized, as one might expect. I then reinforce that idea by
13He explains why countries develop an “industrialized core” while the rest remains an “agricultural periphery.”Krugman’s (1991b, p. 483) key insight is that, “in order to realize scale economies while minimizing transport costs,manufacturing firms tend to locate in the region with larger demand, but the location of demand itself depends onthe distribution of manufacturing.”

providing relevant background on the administrative structure and public finances of the British
and French colonial state.
3.1 The lack of clear investment rules
Colonial documents do not present a systematic investment strategy within or across colonies.
Investments were not proportional to district population (cf. Figure 1), since the needs of the local
population were not a major concern: colonial officials on the ground responded to their superiors
(upward accountability), not to the colonized (downward accountability). Investments were more
responsive to European settlers, but ultimately colonial officials were not accountable to the settler
minority either. The interests of the British Colonial Office or the French Ministry of the Colonies
did not necessarily coincide with those of settlers, itself a diverse group comprising administrators,
traders, farmers, missionaries and sundry Europeans (Darwin, 2012). Granting additional land to
European farmers, for instance, risked alienating the local population even further. Some settlers
in Kenya created the European Taxpayer’s Protection League to shift the tax burden (further)
away from Europeans to the local population (Gardner, 2012, p. 98), hoping to benefit from public
investments without paying for their cost. In sum, investments were not simply a function of the
settler population.
The lack of a systematic investment strategy is perhaps the most surprising aspect of colonial
policy if we use Weberian states as reference categories. It is less surprising if we consider that
communication and knowledge of the territory were also limited, which made policy coordination
difficult between the core and the periphery (Darwin, 2012, p. xii; Delavignette, 1968, p. 63).
British and French colonial officials routinely applied for grants in aid to the respective ministries
with the goal of conducting infrastructure projects and complement colonial tax and tariff revenues.
Yet, the metropole precisely strove to reduce the quantity of funds, especially of grants-in-aid,
available to colonial governments (Constantine, 1984, p. 14, p. 84; Gardner, 2012, p. 9), resulting
in financial uncertainty and short-term local decision-making.
11
While expenditures presumably responded to particular needs, “no explicit investment strategy
can be found in [French colonial] local budgets. Motivations reported at the beginning of each local
budget explain the general level of annual resources but do not motivate the spatial distribution of
public goods provision” (Huillery, 2009, p. 181). British local budgets present a remarkably similar
focus on detailed descriptions and administration rather than policy: “colonial tax and spending
patterns did not follow a similar logic throughout British Africa” (Frankema, 2011, p. 147) in part
because “[Britain] did not strive to apply a common financial policy to the various dependencies”
beyond “general instructions [...] from the Secretary of State for the Colonies” (Stammer, 1967,
p. 194).
3.2 Autonomous administrators in a decentralized colonial state
Examining British and French colonial institutional structures provides some further insights on
why the state was decentralized and decision-makers were rather autonomous. It also provides us
with a better understanding of the public finances of the colonial state and on their similarities
between these two empires. These similarities are not emphasized in the literature because much
historical work on colonial policy focuses on how French ideas of assimilation and direct rule
differed from British ideas of association and indirect rule (Crowder, 1964; Strang, 1994; Sharkey,
2013) and because studies of colonial finance and administration tend to focus on one empire
(Delavignette, 1968; Suret-Canale, 1971; Constantine, 1984; Gardner, 2012).14 At the top of the
colonial hierarchy, there were the Ministry of the Colonies in Paris and the Colonial Office in
London. These ministries sent a Governor to the colony that acted as the main link between the
metropole and the civil servants in the colony, which included administrators, teachers, judges,
engineers, doctors and nurses. Each district (or cercle) was led by a district head called District
Commissioner (Commandant de Cercle).
District heads stationed far from the colonial core had much latitude in local policy and im-
plementation because of physical distances and poor transportation and communication networks.
14There are historical studies spanning both empires on other issues, notably economic history (Hopkins, 1973)and labor policy (Cooper, 1996).
12
“The administrative organization was officially centralized but effectively decentralized,” making
district heads “the real chiefs of the French empire” (Huillery, 2009, p. 181; Delavignette, 1968).
They oversaw the administration, taxation, justice and other public services in both empires (Suret-
Canale, 1971, p. 72). District heads were also in charge of relations with village chiefs, and the
former partly relied on the latter for policy implementation and revenue collection. “Local chiefs
[in British colonies] had a guise of autonomy in their local jurisdictions, but they were actually
guided and supervised by the British colonial administrators” (Strang, 1994, p. 149). Similarly,
local chiefs in French West African villages were an autonomous and useful but ultimately subor-
dinate figure whose “influence [was limited] to small areas” (Huillery, 2009, p. 181). Lugard (1922)
devised his theory of indirect rule with the British Empire in mind, but its practice extended to
parts of the French empire.15 Since the colony was not an organized entity with a central plan-
ner and clear investment rules, I turn to quantitative data sources to understand what factors
underpinned the spatial distribution of colonial public investments.
4 Data
4.1 Sources
To the best of my knowledge, this paper presents the most extensive data on investments at
the colonial district level for French West Africa (collected by Huillery, 2009) and for the main
eight British colonies under the Colonial Office (original data collection): Benin (formerly Da-
homey), Burkina Faso (Upper Volta), Cote d’Ivoire, Ghana (Gold Coast), Guinea, Kenya, Malawi
(Nyasaland), Mali (French Soudan), Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Tanzania
(Tanganyika), Uganda, Zambia (Northern Rhodesia). One important advantage of focusing on
these colonies is their rather homogeneous institutional structure within each empire (Section 3).
Unlike French Algeria or British Southern Africa, most of East and West Africa was not integrated
15Sharkey (2013) considers the difference in that regard between the two empires a matter of degree, consistentwith the move by Gerring et al. (2011, p. 378) “to understand systems of [direct and indirect] rule along a continuumthat reflects the degree of central control.”
13
into the French and British empires until late in the 19th century.16 Due in part to their similar
colonial experience, all 16 colonies became independent around 1960.
Another important advantage is that record-keeping procedures were very similar within each
empire, since all administrators reported to the Ministry of the Colonies in Paris and the Colonial
Office in London. Huillery (2009) collected the original French records for selected years in the
1910-1939 period.17 I collected British colonial records from 1915, 1920, 1927, 1928 and 1938
as a function of availability of disaggregated data. They often contain detailed information on
demographics, education, health, infrastructure investments and other activities (Figure A.9 shows
a page of a British Blue Book and a page of a French Compte Definitif). I georeference colonial
investments by taking advantage of detailed colonial maps with district boundaries, which enable
the use of districts as the units of analysis (Figure A.10 presents a map published by the Colonial
Office).18
Colonial records are not without problems, however. Data on infrastructure, health and ed-
ucation is presented at the town or district level in some years but is too aggregated in others
and table formats often change, making comparisons across years challenging. They also contain
data gaps, such that some data are available in some years but not others. Further, population
censuses were far from accurate. In the early colonial period, some data may have been educated
guesses rather than censuses in the way they are currently conducted (Cooper, 2005; Frankema
and Jerven, 2014).
To explain colonial investments, I collect a set of sources that provide information on the
physical, geographic, social and economic characteristics of the territory. To test whether ob-
servable ethnic characteristics affect colonial investments, I draw on Murdock’s (1959) dataset of
pre-colonial ethnic group characteristics because it provides useful proxies of pre-colonial economic
and political development, such as intensity of agriculture, settlement patterns, the size of local
16There are exceptions. Part of the hinterland in Senegal and Ghana had been colonized much earlier, whileZambia was incorporated as Northern Rhodesia into the Colonial Office only in 1924. Tanzania, then Tanganyika,was under German occupation prior to World War I and incorporated to the British Empire as a League of NationsMandate only in 1922.
17Technically the panel extends to 1956, but data are mostly missing post-1939.18Colonial district boundaries are relevant today. With some exceptions, many have changed little over time and
around 80% of them remain in place today. Districts today are often partitions of a larger colonial district.

communities and level of political centralization. I also code two pre-colonial ethnic characteristics.
I use two indicator variables to code whether the district was located in a pre-colonial kingdom or in
an acephalous society (Olson, 1996; Encyclopedia Britannica, 2016), thereby extending Huillery’s
coding for French colonies to British ones. The other is an ordinal variable for low, medium, or
high historical presence of Islam across districts, improving a rough map by Bartholomew (1913).
New data on trade and natural resources allows me to test economic explanations of colonial
investments. The sources for pre-colonial trading posts come from Slave Voyages (2013), Curtin
et al. (1995) and Huillery (2009). Data for natural harbors and capes comes from Ramsar (2016)
and Ports.com (2016), which contain information on multiple geographic characteristics.19 To
explain investment diffusion, I calculate the geodesic distance from each district capital to the
closest trading post. Natural resources data comes from Hubert’s (1922) map (Figure A.11), likely
the most comprehensive on the issue for pre-1940 West Africa. The other is a detailed worldwide
map by Kuhne (1927). I complement these two main sources with an early publication by the
United States Geological Services (USGS, 1921) that also has world coverage but is much less
detailed.
The data also contain several geological, physical and geographic controls. Huillery (2010) col-
lected several of these physical and geographic attributes for French West Africa, such as distance
between the district capital and the coast, altitude and the presence of navigable rivers—which
I complement with a map by C.S. Hammond (1921). I extend those variables to include British
colonies and collect additional ones. Altitude, for instance, is a rough proxy for disease envi-
ronment, notably for malaria (World Health Organization, 2016), but to better capture disease
environment I use a geocoded map of malaria prevalence around 1900 (Lysenko and Semashko,
1968) and FAO tsetse fly data (Alsan, 2015). Those data are important in tropical Africa, “often
referred to as the white man’s grave” (Darwin, 2012, p. 138).
19Tables A.4 and A.5 provide the list of natural harbors and capes as well as of trading posts and include testsof covariate balance for both indicator variables.

4.2 Descriptive statistics
Infrastructure investments levels varied widely by colony (Figure 3). For instance, if we consider
investments per capita, levels of investments in Ghana are similar to those in Guinea but much
higher than those of any other British colony.20 Since colonies received little aid from the metropole,
differences in budgets are largely due to differences in the revenue raising capacity of colonial
governments (Hopkins, 1973, p. 190).

Note: Expenditures in infrastructure per colony varied widely absolutely and per capita. Except for Ghana, percapita investments in British colonies were lower.
I quantify inequality in investments by computing Gini indices by colony (Figures 4-6).21 The
indices are calculated using district-level investments. While the literature computes regional Gini
indices (Milanovic, 2016), regions and districts are not individuals and hence the administrative

divisions of the state affect those indices.22 In the case of infrastructure expenditures, they are
around or even above 0.7 in the average British colony and around 0.6 in the average French
colony. They are usually around or above 0.4 for education (proxied by students per district)
and health (proxied by doctors and nurses per district).23 Inequality is especially high in British
colonies compared to French ones. This could be in part the result of the redistributive federal
budgets in French West Africa, while between-colony variation could be the result of many colony
and empire factors beyond the scope of this paper. To visualize the variation, Figure 7 maps
infrastructure expenditures along with the presence of the most valued natural resources by district.
The correlation pattern varies by colony, seemingly high in Ghana but nonexistent in Nigeria, and
overall it appears weaker than one might expect.

Infrastructure expenditures per capita
Note: To quantify inequality, each colony’s Gini index is calculated using district investments (rather than individualincome, which colonial data do not provide) as the units of analysis.
Infrastructure expenditures in a district-year amount to around 50,000FRA on average, in
1910 real French francs, in each empire (Table A.1). They are a bit more evenly spread in French
West Africa, as also shown by the figures plotting Gini indices. French per capita expenditures
(96,000FRA) are three times British expenditures (31,000FRA), but much of the difference is
22Interstate inequality could be altered by redrawing district boundaries. While it happened sometimes, I findthat over 80% of colonial district boundaries in the 1920s and 1930s persist today.
23Gini indices generally use individual income data to measure economic inequality, where 0 means perfect equalityand 1 perfect inequality. If investments were perfectly equal across districts, the Gini index would be 0. If onedistrict received all investments and the others received nothing, it would be 1.

driven by low investments in British East African colonies—the French had no colonies in East
Africa. Within West Africa, expenditures per capita are “only” 40% higher in French colonies
(Table A.2). Investments are higher in West Africa for internal and external reasons. The region
was richer than East Africa already in the pre-colonial period and conquest started earlier, two
factors which may have resulted in a more developed tax and tariff system during colonialism.
Colonial records show that most expenditures were devoted to buildings and premises of various
sorts, such as residences of district officers in both core and remote areas, port authorities, and
various transportation expenditures such as railroads, roads, bridges and harbors (Table A.3).

Figure 7: Public infrastructure investments by district (1910-1939 average) and location of baseand noble metals (1922)
Note: This map illustrates the colonies under study, their levels of infrastructure investments, and whether a districtcontained some base metal (e.g. iron, zinc) and some precious metals or stones (gold, silver or diamonds). Thecorrelation appears to exist in some countries (Ghana) but not in others (Nigeria). There is much variation withincolonies, some perhaps unexpected. The northernmost district in Mali, formerly French Soudan (SOU), had highper capita investments because of Timbuktu.
The average British and French district received close to no investments in sewage and water
sanitation or in electricity and lighting, infrastructure systems that were too costly for meager
colonial budgets.
5 Results
This section begins by examining the role of pre-colonial trade on colonial investments. The focus
is on coastal colonies, where accidented geography provides us with some exogenous variation in
the establishment of pre-colonial trade. Next, I consider possible alternative explanations such as
natural resources and ethnic characteristics. I then examine the diffusion of colonial investments in
both coastal and inland colonies. Finally, I conduct some exercises to determine whether investment
19
inequalities in 1910 increase, remain stable, or decrease during the colonial period up to World
War II (1939).
I first model the relationship between coastal geography, one the one hand, and pre-colonial
trade and investment outcomes, on the other, in coastal colonies (Table 1). The reduced form
equation takes the following form:
log(Yij) = β0 + β1Gij + LTβ2k +NTβ3k + STβ4k + ηj + εij, (1)
where Y is the colonial investment of interest in district i in colony j. These are district infras-
tructure expenditures (adjusted to 1910 French francs), an indicator for the presence of a railroad
in the district, the number of students and the number of health staff. Infrastructure, education
and health outcomes are logged to increase normality. G stands for natural harbors and capes, L
stands for other locational fundamentals, N for natural resources and soil quality, S for colonial
district population, area and pre-colonial socioeconomic characteristics. η are colony fixed effects
that are included in all models. They account for colony-specific variation in issues ranging from
different baseline levels of investments to possibly different reliability of the colonial records across
colonies.
The two-stage least squares (2SLS) models follow an analogous logic to equation 1 but in-
strument pre-colonial trade. The exclusion restriction claim is that natural harbors and capes
affect colonial investments because they enabled pre-colonial trade in the first place. Many mecha-
nisms may account for the relationship, however, such as early investments in forts and European
settlement, which I explore later. The model is as follows:
Tij = γ0 + γ1Gij + LTγ2k +NTγ3k + STγ4k + ηj + υij (2)
log(Yij) = β0 + βIV Tij + LTβ2k +NTβ3k + STβ4k + ηj + εij, (3)
where T is the presence of a pre-colonial trading post and all other variables follow the notation
described above (equation 1).

21
Results from Table 1 strongly suggest that accidented geography affected the location of posts
(first-stage models 1 to 3) and that it also affected infrastructure, education and health invest-
ments (reduced form models 4 to 7).24 Next, I estimate the effect of pre-colonial trading posts on
colonial investments using ordinary least squares (OLS) models alongside the second stage of the
two-stage least squares (2SLS or instrumental variable (IV) models). Since the outcome is logged
to reduce right-skew, the percent change in Y can be interpreted as 100βIV . The presence of a
pre-colonial trading post increases expenditures in infrastructure and the number of students by
about 200-300% and the number of health staff by around 100-300%, depending on the specifica-
tion. The magnitude varies but the effect is large across specifications. Pre-colonial trade does not
increase the likelihood of having a railroad. This null effect on railroads makes sense, since rail-
roads were inland investments, and suggests that a different logic may account for transportation
infrastructure, as discussed below, since railroads served extractive purposes further inland while
early trade usually took place in coastal areas.
5.1 Other explanations
Investments are likely explained by other factors beyond pre-colonial trade. I consider some plau-
sible complementary explanations, notably natural resources and ethnic characteristics in Table 3.
Explanatory variables in the table are also present in equations 1-3 as controls. They are included
simultaneously because pairwise correlations between them are always below 0.4, reducing multi-
collinearity concerns.25 Infrastructure expenditures are higher and railroads more likely in districts
with noble metals (gold, silver) or diamonds, where they are associated with a 68% increase in
infrastructure expenditures.26 However, the effect does not extend to non-extractive investments
(education and health) and base metals, a less valuable but abundant type of metal in West Africa
(Figure A.11), do not affect any investments.
24The instrument and the main predictor are balanced across a set of observable pre-colonial characteristics(Tables A.4 and A.5).
25The exception is a 0.59 correlation between distance from the coast and the tsetse fly index (Alsan, 2015).26Benin, Kenya, Malawi, Niger and Uganda did not have any gold, silver or diamonds as of 1920. The other 11
colonies had at least one of these three resources.

23
One of the main explanations for colonial inequality concerns the divide and rule strategy
(Horowitz, 1985). While the practice was common, it remains unclear whether there was a system-
atic heuristic behind it. For instance, did Europeans invest more in pre-colonial kingdoms because
they were more developed to begin with and hence initial costs were lower? This finding would be
consistent with existing literature, which shows that pre-colonial kingdoms provide better public
services and are more developed today (Gennaioli and Rainer, 2007; Michalopoulos and Papaioan-
nou, 2013; Bandyopadhyay and Green, 2016). Also, colonialists might have invested less in more
ethnically diverse districts if these were more difficult to control. I find very modest support for
these hypotheses using several proxies.
Using Murdock’s (1959) map of ethnic homelands, I construct an index of ethnic fractionaliza-
tion at the district level and find that it only reduces the likelihood of a railroad in the district.
The same applies if I use a raw measure counting the number of ethnic homelands per district.
Perhaps surprisingly, higher pre-colonial political centralization does not increase investments. An
alternative specification using a pre-colonial kingdom indicator is not significant across investments
either, and bivariate correlations are usually below 0.1. Pre-colonial kingdoms provide better pub-
lic services and are more developed today, but higher levels of colonial investments do not appear
to be the mechanism behind this finding. A simple ordinal measure for prevalence of Islam (mi-
nority, mixed or majority) suggests that more Muslim districts seem to have fewer students, but
causality remains unclear. In Nigeria, for instance, the Muslim North was ruled indirectly, and
hence investments were lower. However, (Lugard, 1922) suggests that the reason for indirect rule is
the North’s higher political centralization under the Hausa States. I also test other characteristics
such as settlement patterns of the ethnic group and indigenous slavery and find insignificant re-
sults. While divide and rule was a common strategy, especially in British colonies (Wucherpfennig,
Hunziker and Cederman, 2015), some of the main observable ethnic characteristics mentioned in
the literature do not predict investments systematically. These null results do not rule out alter-
native explanations. Rather, they suggest that “ethnic” divide and rule strategies may have been
context-specific instead of systematically relying on observable local characteristic.
24
Only two patterns emerge clearly from Table 3. First, African population is always posi-
tively correlated with investments. Investments may not have been blind to population and locals
migrated to more developed districts. Second, the table also presents a correlational but coher-
ent picture to account for the presence of railroads, the one investment that is not explained by
pre-colonial trade. They were built in districts without rivers, such that the two appear to be
substitutes; with natural resources, supporting an extractive logic; and that were less ethnically
diverse, less malaria-prone and more populated. Beyond these two patterns, alternative explana-
tions have a limited role in explaining colonial investments in infrastructure (other than railroads),
health and education. For instance, distance to the coast, a standard control, is negative across
investments as expected but not always significant. Similarly, coefficients for disease environment
proxies are usually negative but often insignificant.
5.1.1 Differences by empire
I consider alternative explanations further by splitting the sample by empire, since considering
them together may be masking relevant heterogeneity. While not the focus of this paper, I provide
some correlational results in light of the literature comparing both empires (Hopkins, 1973; Cooper,
1996; Lee and Shultz, 2012). Figure 8 presents coefficients from the same models as in Table 3 but
now split by empire. As expected, investments increase with population and pre-colonial trade in
both empires.
Colonialists held many racial prejudices in both empires. However, British investments seem to
discriminate more than the French based on district ethnic diversity or on an alternative measure
using raw number of groups in the district. They also invest less in districts with more Muslim
presence. We do not observe these correlational patterns in French colonies, consistent with the
notion that the British practiced divide and rule more than the French (Wucherpfennig, Hun-
ziker and Cederman, 2015). Finally, the estimates on pre-colonial political centralization are also
insignificant in both empires.

5.2 Diffusion and persistence of colonial investments
How did investments diffuse within East and West African colonies from early enclaves to the rest
of the colony? To the limited extent investments spread across districts, I examine whether early
trade was relevant or instead its importance was circumscribed to these colonial development hubs.
Colonial state expansion was progressive and limited because of European financial and manpower
constraints. In this logic of gradual expansion, I test whether pre-colonial enclaves were important
departing points to expand inland since there is evidence that “agglomeration economies attenuate
with distance” (Rosenthal and Strange, 2004, p. 2120). I use linear models of the form:
log(Yik) = β0 + β1T + β2DT + β3DC + β4P + β5E + ηk + εik, (4)

is the logged number of Europeans, a potentially relevant mechanism. I include a pre-colonial
trading post indicator and the standard coastal distance measure to examine variation between
districts without a trading post that is not already explained by coastal distance. I use geodesic
distances between district capitals advisedly because it eliminates the endogeneity of man-made
infrastructure such as roads and even local geography such as hills and rivers.

Increasing distance from a pre-colonial trading post reduces all types of investments (Table
4). The results are not identified but suggest that the limited diffusion of colonial investments
we observe is partly a function of early trade, consistent with Gaikwad’s (2014) findings in India.
The negative effect of increasing distance from early trade likely goes through many channels, one
27
of which could be European settlers. They chose districts that were centers of economic activity,
which should compound even further the advantages of early trading locations (such as Dakar and
Lagos) and their surroundings (Thies and Abeokuta, respectively). Including European settlers
in the model supports the idea that they are a relevant mechanism across investments (Table 5).
The effect of distance from a pre-colonial post remains negative but is smaller across investments,
consistent with the idea that settlers influenced the diffusion of investments.
I also examine the persistence of public investment inequalities during the 1910-1939 colonial
period.27 Serial correlations show that inequalities are persistent in both empires for the three
main public investments (infrastructure, education and health), especially in education and infras-
tructure (Figures A.1 and A.2). To examine whether these disparities increase, I use autoregressive
models in the case of French West Africa (Tables A.6-A.8), where the panel structure is less unbal-
anced than in British colonies. Results are mixed in infrastructure, while in education and health
initial disparities either remain constant or increase. Overall, the exercises in this section do not
disentangle the mechanisms of persistence, as future research should. They show, however, that
the importance of early trade extends beyond initial enclaves; that disparities in public investments
tend to remain stable or increase; and that European settlers are a mechanism in this feedback
loop of weakly increasing disparities within colonies.
6 Conclusion
In this paper, I present evidence that investments in infrastructure, health and education within
British and French African colonies were strikingly unequal across districts. Using district-level
data, I quantify this inequality in investments by constructing a Gini index for each of the 16
colonies and each of the main three investment categories. Inequality was around 0.7 in British
colonies and around 0.5 in French colonies. Those regional inequalities are higher than in many
countries in recent decades (Milanovic, 2016).
27Pre-20th century differences in investments are difficult to measure mostly because systematic records for thepre-colonial period are scarce.
28
I provide evidence that pre-colonial trade, rather than natural resources or ethnic characteris-
tics, is the root cause for this high within-colony inequality in investments. In doing so, the focus
of the explanation shifts away from an identity logic to an economic logic. Divide and rule along
regions and ethnic groups was common, especially in British colonies (Wucherpfennig, Hunziker
and Cederman, 2015). However, I find little support for some of its observable implications. In-
stead of systematically relying on some ethnic or regional characteristic, divide and rule strategies
may have been context-specific. To identify the impact of trade, I instrument pre-colonial trading
posts with the presence of a natural harbor or cape—adapting Jha (2012) and Gaikwad’s (2014)
instrument for the case of South Asia—to increase confidence in the causality of the estimates.
Colony fixed effects increase comparability and account for institutional and other colony-level
factors.
The positive effects of early trade on public investments are not circumscribed to those trading
enclaves: infrastructure, education and health investments decrease the further a district is from a
pre-colonial trading post. Findings in developed countries showing that “agglomeration economies
attenuate with distance” (Rosenthal and Strange, 2004, p. 2120) may extend to colonies in their
early stages of state formation and development. Yet, I show that investment inequalities across
districts do not diminish during much of the colonial period (1910-1939). Those locations with an
early geographic advantage, typically colonial capitals and trading posts, became centers of colonial
economic activity and likely benefited from complementarities between investments, consistent with
a logic of increasing returns. I also provide some evidence that European settlers are a mechanism
behind this inequality. They came to East and West Africa in any significant numbers only in
the 20th century, but they reinforced this feedback loop between pre-colonial trade and colonial
investments.
More broadly, the findings speak to research that highlights the importance of pre-colonial
trade for current development in Africa and South Asia. The pre-colonial slave trade had nefarious
consequences at the “point of origin” or extraction (Nunn and Wantchekon, 2011). Perversely, it
increased colonial investments and development at the African “point of destination” where the
trade took place. This result is consistent with historical accounts in Africa (Curtin et al., 1995)
29
and with Gaikwad (2014), who shows that areas in India with pre-colonial trading ports are more
developed today. Compared to East and West Africa, Europe’s trade with India in textiles and
raw materials was much more advanced and industrialized. Yet, I find that pre-colonial trade
increased colonial development even in a highly extractive context where slaves a central export
until the 19th century.
There are at least two areas for further research. One concerns differences between empires.
Why were infrastructure, health and education investments in British colonies even more unequal
than in French ones? One reason could be institutional: French colonies had a redistributive federal
budget that aided poorer colonies while the British did not. Also, this paper finds weak evidence
that the British were more discriminatory in their investments insofar as, unlike the French, they
may have invested less in districts more ethnically diverse districts and in those with higher Muslim
presence. These patterns are consistent with existing literature, but they ought to be explored
further. A second area of future research concerns the consequences of colonial investments for
current welfare (Huillery, 2009). Existing research focuses on the long-term impact of colonialism,
but future research should aim to better understand and quantify the long-term impact of pre-
colonial trade and colonial investments on current outcomes in former British and French Africa.

Appendix B: Persistence during colonial times
Education inequalities seem persistent: serial correlations for the number of students and teachers
in French West African districts are around 0.8 (Figure A.1) across years with sufficient data
between 1910 and 1939. In health staff, the correlation is above 0.5, and for infrastructure it is
around 0.95 for any of the three pairwise correlations. In the case of British colonies, the number of
schools, students and health staff also correlate at 0.8 or above, while for infrastructure investments
it is 0.57 (Figure A.2). The pattern is overall similar in both empires: those ahead in the 1910s
are still ahead at the eve of World War II, even if shocks such as the Great War and the Great
Depression reduced overall levels of revenue collection and therefore investment (Gardner, 2012,
p. 6).

I test more formally whether investment patterns over time converged or diverged for the
case of French West Africa using autoregressive models with one lag (AR1) (equation 5). One
advantage of AR1 models, as opposed to simple serial correlations, is that the constant controls
for deterministic trends.28 I also examine whether initial levels of colonial investments (Iit0) predict
28In other words, the constant would capture a constant increase across districts due to inflation (already ac-counted for by using real 1910FRA), a larger budget, or other factors.

Investments (I) are indexed by district i and year t. Models 1 and 2 in Tables A.6-A.7 use levels
of investments, while models 3 and 4 are logged to reduce dependence on outliers. Equation 5 is
an AR1 process that includes the initial value (t0) of I in the time series to adjust for baseline
levels of I (models 1 and 3). Equation 6 considers changes in investments over time (models 2 and
4). β > 0 indicates increasing divergence and β < 0 indicates convergence when compared to the
distribution at t0. The approach of equation 5 is more rigorous than that of equation 6 but the
cost is a reduced sample size. Because the panel is unbalanced and incomplete, the previous value
It−k (equation 6) is not necessarily the previous year as in equation 5 but the nearest previous
year for which there is data available. I report both for completeness because there can be biases
in either modeling strategy given the gaps in the data.
Inequality was already high in the early 1900s, yet all models except one indicate either increas-
ing (β > 0) or constant (β = 0) disparities in educational, health and infrastructure investments,

consistent with a logic of increase returns. Teachers per district in 1915 predict a later increase in
teachers, and the same seems to apply to health staff. The results on infrastructure investments
vary depending on the specification. Public facilities such as schools and hospitals likely benefited
from complementarities and economies of agglomeration more than basic infrastructure, part of
which was intended to create transportation networks with more remote areas in the colony.
