ABSTRACT
This paper used a series of two way fixed effect models to test the hypothesis that higher
military expenditure will boost the quantity and quality of innovation. The dataset in this paper is
a merged dataset from the World Development Indicators (WDI) dataset and the Quality of
Government (QOG) dataset. It covers 159 countries between 1989 and 2009. Unlike the existing
studies, this paper used multiple indexes to measure innovation, including GNI, Industrial Output,
Service Output, High-Tech Exports, the number of Patents, and the number of Scientific Articles.
These six independent variables would jointly capture the full essence of innovation in terms of
both quality and quantity. Moreover, Military Expenditure per Soldier and its lags are used as the
dependent variable of interest. A series of other control variables are used to capture different
countries’ government quality, educational level, financial market conditions, and infrastructure.
Four of the innovation indicators (GNI, Industrial Output, Service Output, High-Tech Exports)
have shown unambiguously positive correlation with military innovation. Only two indicators
(the number of Patents and the number of Scientific Articles) show relationships with military
expenditure that are insignificant. Considering the fact that military-related Patents and Scientific
Articles are underreported due to the military secrecy policy, I am confident that, if all the
military innovations are disclosed, all six proxies for innovation would show evidence that
v
military expenditure can boost innovation. Finally, this paper provides reasonable grounds for
policymakers to reevaluate the use of their defense budget.

INTRODUCTION
“Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. The world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children... This is not a way of life at all, in any true sense. Under the cloud of threatening war, it is humanity hanging from a cross of iron.”
------Dwight D. Eisenhower, Former U.S. President, April 16, 1953
Above is a famous citation of former U.S President Dwight Eisenhower. It tells us that
every dollar spent by the military comes from a dollar cut in the budget for other projects. There
are many different issues needed to be resolved in the government’s agenda and all those issues
are competing for funding. In 2012, the US defense spending equals 37% of the federal
government budget (Friends Committee, 2013). This is the largest pile of the federal budget.
Under the context of massive government deficit, many politicians, interest groups, lobbyists are
targeting at the defense cut so there will be more money available to other public sectors.
However, cutting defense budgets may result in a series of problems for many countries. For
example, countries may have to reduce the sizes of their armed forces due to the budget
reduction, which would in turn lead to insufficient forces to protect the national security. Also,
lower defense budgets may cause huge unemployment because soldiers in the armies, workers in
the military manufacturing industry and researchers in military research entities may face the risk
of being laid off. Except for the two negative effects I mentioned above, a defense cut would also
reduce innovation in the society. So the aim of this paper is to study how lower defense budget
leads to less innovation.
2
In recent centuries, there are many great innovations generated from the military sector. For
example, submarines, rockets, satellites, nuclear energy, jet aircraft, computers, and the Internet
originate from military laboratories. As the economy becomes more developed and the financial
market become more efficient, those military inventions are being quickly adapted for civilian
use and become the new sources for economic growth.
Several factors explain why the military sector is responsible for so many revolutionary
innovations. First, almost all governments have very strong desires to master the latest
technologies and arm their soldiers with the best equipment, so that they can maintain internal
stability and protect homeland security. Second, the defense department has sufficient resources
and capacities (funds, human capital, knowledge reserving, and consistent policy backup) to
explore the most advanced theories and technologies in the world. Third, like all other public
goods, innovation has long been underinvested in the private sector because firms concerns about
the high fixed cost and free riding problem (Jha, 2010). The thesis tests the hypothesis that
increased military expenditures will lead to higher levels of innovation in the whole society. The
dependent variable is innovation. Historically, researchers have used many different proxies for
innovation: the number of patents, the growth in real GDP, and the growth of multifactor
productivity (Bronwyn, 2011). In my thesis, I use multiple variables to represent innovation. My
independent variables will be military spending per soldier, which measures a country’s
investment in military without biasing countries with huge populations like India and China. My
main model in this thesis is a two way fixed effect model including a series of different controls
as discussed above. Also, the model would include lags of the log (Military expenditure per
soldier). The number of lags is dependent on my trail and error results: I would replicate the
3
model with different number of lags, and I choose the model that has the biggest explanation
power (i.e. largest Square).
Eventually, four of the six proxies for innovation (GNI, Industrial Output, Service Output,
High-Tech Exports) have shown significantly positive correlation with military expenditure.
Only two proxies (the number of Patents and the number of Scientific Articles) show ambiguous
relationship with military expenditure. Due to the secrecy policy in the military sector, military
innovations are underreported in Patents and Scientific Articles. So if we can get a full data
collection about Patents and Scientific Articles (covering all military innovations), I believe that
all proxies for innovation would show evidence that military expenditure can boost innovations.
Given the updated understanding of military expenditure, policymakers should reevaluate
their countries’ defense policy and be more careful with the defense cut. Deng Xiaoping, the
leader of the Chinese Economic Reform in 1978, had a famous theory: “Science and technology
are primary productive forces” (Deng, 1988). Innovation and technology are the leading forces to
improve productivity, expand market, and provide labor opportunities. Thus, if cutting military
spending would slow down the development of civilization, maybe the government should be
more cautious in cutting defense budget. Also, governments should make policies that assist the
military sector to be more efficient and effective in generating new innovations. Finally,
policymakers should help to expand the application of those military innovations in the civilian
sector so that the economy would have more opportunity for growth.

LITERATURE REVIEW
November 9th 1989 is a special day in human history, because that is the day when the
Berlin Wall collapsed. To the German people, it meant the reunification of the country; but to the
world, it meant the end of the Cold War and the success of the democratic movements in Europe.
In the following 5 years, the world witnessed a massive (20%) reduction in global military
spending. Thus, more public money that was formerly spent in the military sector could be used
for private consumption and investment (Mintz and Chan, 1991). As a result, many countries
experienced an economic boom. Ke-young and Peter (1993) called this the “peace dividend”.
They found that an increase in a nation’s military spending has a significant negative externality
on its neighbors’ economic growth, because it increases the risk of conducting economic
activities in neighboring countries. As a result, the neighboring countries have to set aside more
resources to achieve relative military balance, which further hinders economic growth. A
simultaneous cut in defense spending would improve overall security and foster economic
growth in all countries.
Beginning in 1996, global military spending gradually increased again and this trend has
been maintained for nearly two decades. Moreover, the increasing concentration of military
spending appeared as a new feature of global military spending—a smaller number of countries
possess a much higher weight of world military spending (Anup, 2013). Such trend is mainly
5
brought by the belief that a larger military expenditure can lead to economic growth as well as
innovation in the society.
Proponents of increasing military spending like Chowdhury (1991) and Benoit (1973)
argue that military spending is delicately planned public spending which addresses idle capacity,
unemployment, and under-consumption problems resulting from low domestic demand. Others
made similar arguments on how military expenditure can help the economy. It is claimed that the
military has been long perceived as “the employer of last resort” (Jeffrey et al, 2011:514), in
which the development of the military creates massive demand for labor, and the military
personnel receive education, training, medical care, housing, and food. The investment in
training and education further help build up human capital because many of the soldiers and
engineers will participate in the production in private sector in the future (Inkeles and
Smith,1974). Stockwell and Laidlow (1981) contend that the military serves as an important
modernizing institution in undeveloped countries, where the military effectively educates
modernized attitudes and attracts foreign investment and donations. By adopting new disciplines,
achieving motivation and pride in national citizenship, the military helps break down the old
value system, and traditional means of production (Weber, 1921; Andreski, 1968). For example,
Cheung (1988) shows that the Chinese People's Liberation Army (PLA) has been responsible for
building up farms and factories, construct railways and roads, developing communication lines,
training 1.5 million technicians, and intensifying the connection between the outback China and
eastern China.
On the other hand, the positive impact of military spending on the society can also be
seen from the trend of innovation. Comparing to traditional military development, which merely
6
brings more casualties and disasters, modern military development brings more positive
contributions to human civilization. In the past two centuries, the military has initiated many
state of the art innovations, which fundamentally changed modern civilization. Ruttan (2006)
compared the public and private research potential and identified the six major innovations
which could not have be discovered in the private sector: aircraft, nuclear power, the computer,
the semiconductor, the Internet, and space communication and earth observing industries. Apart
from those great innovations in the past, the military sector is actively participating in other
cutting edge technologies. According to a report of the PEW project, the US Department of
Defense (DoD) has begun ambitious R&D programs to solve many sophisticated energy issues,
such as maintaining stable fuel supply in the battlefield, providing safer and non-explosive
energy, and reducing energy production cost (Joshua et al. 2011). DoD’s budget for energy
security initiatives in 2011 was $1.2 billion and this is estimated to grow to over $10 billion per
year in the next two decades (Joshua et al, 2011). Clearly, there is enough empirical evidence
showing innovation could be cultivated from the military backyard, yet the purpose of this paper
is not just to show that the military will generate innovation. Essentially, it is to investigate
whether higher military expenditure will increase overall innovation. Scholars have long been
debating this question but no agreement has been reached.
Looney (1988) and Jeffrey (2008) contend that the impact of military expenditure on
innovation is more positive for countries with lower debt levels than those with higher debt level.
Jeffrey (2008) also concluded that military innovation is becoming more congruent to the private
innovation. More synergies rather than trade-off are revealed between the military and private
innovations, so military and private innovation mutually support each other. Gamota (1985)
7
used research data from 1960 to 1985 to show that defense spending has a critical role to
promote the increasing of non-military technologies. Correspondingly, Saal (2001) demonstrated
that military spending has a significant positive effect on manufacturing and industrial
productivity. Joshua et al. (2011: 6) took a similar position and claimed that the military sector
has a peerless advantage in promoting innovations, because the military has kept a good “R&D
infrastructure, the ability to grow demonstration projects to scale, significant purchasing power
and the necessary culture and management infrastructure”.
However, there are also scholars who challenge the innovation promotion theory of
military expenditure. Knight et al. (1996) claimed that increasing military expenditure would
lead to less innovation. First, the military is not governed by the rules of the market. It has too
much price distortion and faces far less competition than private industry. Therefore, military
sector is less efficient than private market. Secondly, higher defense costs will crowd out the
resources and opportunities that should be available to the more productive and competitive
private sector. Similarly� MacNair et al. (1995) studied defense research and development in
NATO countries and conclude that defense R&D is less productive than private R&D investment
for the purpose of driving economic growth. Jacob (2008) also did research to find out the
impact of military R&D on innovation in 25 developed counties from 1985 to 2005. He used the
number of patent to represent innovation in four two-way fixed-effects models. He found that
public R&D has a small but significant crowding out effect on the private R&D. Also, the
defense R&D budget reduces the productivity of private R&D at a statistically significant level.
Rossman (1931) studied the patent filling in England before and after World War I, and
discovered that the war had caused total number of patent filling dropped down by 40% whereas
8
the number of war-related patent doubled. Somewhat differently, Willen (2013) studies the
impact of war on technical innovation in 34 countries over 97 years and concludes that
engagement in war has no impact on the number of patents filed. His model also suggests that
the nature of war (initiator of the war, number of war casualties and nature of the war) is
uncorrelated with the number of patent filling. In the study, he used the fixed effect model and
also included the lags of war. He used the number of patents as proxy for innovation. As for the
dependent variable of interest, he used dummy of war (if a war happen) and country level war
characteristics such as the number of war casualties.
Unlike the previous studies, which only use one proxy for innovation, my thesis will use
multiple measures to represent innovation. Thus, I can capture a better picture about innovation
in terms of both quality and quantity. By doing regressions against all those proxies and
balancing the final results, my study would show a better understanding about how military
expenditure affect innovation.
EMPIRICAL MODEL AND HYPOTHESIS
This paper will use a demand and supply model to analyze the provision of innovation as
a public good. As a major receiver of the government budget, the military sector has huge
influences both on the demand and supply of innovation.
9
The military related demand for innovation comes from the army or the Defense
Department. The primary purpose of the defense budget is to secure the nation, and maintain
strategic advantage over neighbors and enemies. Traditionally, countries forge its army force by
increasing the number of solders, the storage of resources, and the industrial productivity; in
modern times, countries are also competing in the new arena of technology. Military scientists
and engineers become the pioneers for exploring the new worlds of medicine, biology, geology,
physics and nuclear science. Inevitably, an increasing defense budget will increase the demand
for innovation through more investment in training, development and research. Like all public
goods, military innovation has the potential to cause positive externality to society. This means
that the military innovations are not only useful for military purpose, but also useful for private
or business use. Considering the positive externalities, the social optimal demand curve for
innovation should be lower than the former demand curve.
The military related supply of innovation comes from both the military R&D centers and
the weaponry factories. Since military equipment is critical to the national security, weaponry
manufactures are always firmly controlled and backed up by governments (Cameron, 2006). So
even though some weaponry factories are actually private corporations, their special
characteristics make them more like a member of the public sector (Cameron,2006). Compared
with firms in the private sector, the military companies have significant advantages in capital,
human resources and policy support (Atkinson et al, 2012). If an innovation is created in both the
military sector and the private sector, the military firms are more likely to generate more profits
and be more cost efficient. This is because weaponry manufactures can easily utilize their
advantage of capital and government affiliation to capture the civilian market. For example, the
10
Boeing Company frequently applies its military technologies to its civil airplane (Cezmeci,
2005). In contrast, private firms faces huge barriers (both financial and policy constraints) to
expand their innovation to the capture the weaponry market and compete with the existing giant
weaponry suppliers. Clearly, an innovation from the military sector tends to have more
production and capture more market shares. Therefore, it would be easier and cheaper to
generate more innovation from the military sector (as result of the economy of scale). This
implies that the average cost of innovation in the military sector is less than the private sector. So,
as shown in Figure 1, increased demand of innovation from the military sector would reduce the
overall average cost of innovation and shift down the overall supply curve of innovation.
The Figure 1 illustrates how the supply and demand curves for innovation decide the
level of innovation in a society. It helps us to understand how increasing military spending can
motivate innovation.
11
Assume (Q1, P1) is the original market equilibrium, decided by the market supply curve
and demand curve of innovation. Since military innovation is a public goods that implies a huge
positive externality to society, the social supply curve for innovation should be lower than
market supply curve. Thus the deadweight loss (DWL) is generated due to underinvestment in
innovation. As we discussed above, if the government increases military expenditures, more
orders to the military sector would drag down the average cost of providing innovation and shift
down the supply curve. As a result, the new equilibrium will have higher levels of innovation
(Q*>Q1).
From my empirical model, we know that the increased military expenditure would
increase the supply of innovation toward the social optimal level. Thus, the society can reduce

the deadweight loss. In the methodology session, I will further introduce the regression models to
exam how effective can the military expenditure increase the provision of innovation.
METHODOLOGY
The basic model for my thesis is a simple two way fixed effect model. In this model, the
dependent variable !""#$%&'#"!" represents the level of innovation of a country C in year T. In
previous research conducted by Willen (2013) and Ward (2008), the number of patents was the
only proxy for innovation. As discussed above, a patent does not measure the quality of
innovations. Therefore, in this paper, six variables (GNI, Industry Output, High Technology
Exports, Service Output, the number of Patent, and the number of R&D Articles) will be used to
represent Innovation. Although any single one of them could not give a comprehensive picture of
innovation, together they capture both the quantity and quality of the level of innovation.
!"#!"#"$!!"#$%&$'!" is the dependent variable measured by a country’s defense
expenditure per soldier. We do not use the raw military expenditure number because it prejudices
data from countries with small populations and few troops. For countries like Sweden or Israel,
aggregate spending on the military could be low relative to India or China, but this does not
mean the Swedish and Israeli governments do not take military issues seriously and spend little
on military R&D.
!"#$! represents the year specific fix effects and !"#$%&'! represents the country
specific fixed effects. !!" is the error term measuring the external noise and shocks.

(1.1)
Since the basic model only incorporate innovation and military expenditure, it only
gives us a rough idea about how military expenditure affects innovation. Both the sign and
magnitude of the coefficient can be affected by many other factors. In order to get more
convincing evidences about how military expenditures increase innovations, we need to add
controls to our basic model.
In model 1.2, we added the eight controls to the basic model. Democracy is a dummy
variable indicating whether a country has a democratic system. This dummy is included to
consider the possible impacts of government type on innovation. Tertiary is a country’s
enrollment rate for tertiary education. It is included because countries with higher education level
tend to be more productive (Thorpe, 2012). M_freedom is monetary freedom, measuring the
level of price control. We are assuming that a market with less government intervention would
encourage firms to do more R&D projects because their profits from innovation will have more
certainty and less risk. Life_ex is the expected years of living for males. We use males’ life
expectancy to represent a country’s level of stability and conflicts. In countries with a lot of
conflicts, men are more likely to involved into trouble; many of them will be employed by the
government to kill other men and it is really easy for them to kill or be killed. So that country’s
male life expectancy tends to be low. It is also possible that a higher level of conflicts will take
away a nation’s scarce resources that could be useful for doing R&D. This variable is included to
14
separate the effect of conflicts on level of innovation. Credit is the domestic credit to the private
sector. This variable is used to measure the market efficiency or market barriers for companies
trying to raise money. In country with higher market efficiency, it is easier for firms to raise
money to do research. So we need credit to control for the impact of market efficiency on
Innovation; R_spread is the interest rate spread, this variable is used to measure the economic
risk. In an economy with lower risk or uncertainty, people are more confident to invest thus there
should be a higher level of innovation. Therefore, we need to control R-spread. The last variable
we would like to control is the number of internet users per 100 people. This represents the level
of infrastructure. We control infrastructure because infrastructure is a good stimulus for market
expansion that encourage firms to invest in conducting new research (Joshua et al. 2011).

(1.2)
It is possible that the impact of military expenditure on innovation is dependent on some
other variable, so we added two interaction terms in model 1.3. !"#"$%$&!!"#$%!"#!" ∗
!!!"#$%&#'!" is controlled because I believe the level of education affects the marginal effect
15
of military spending on innovation. Given the same level of R&D funding, the country that has
higher education level tend to do more productive of their research.
!"#"$%$&!!"#$%&$'!" ∗ !"#$%&!" is controlled because market efficiency also tends
to affect a country’s efficiency in generating innovation from military R&D. However, the effect
of this interaction term seems to be controversial: on one hand, in countries where market
efficiency is low (high capital threshold, high set up cost, redundant policy restriction), the
military provides the only possible means to develop big technology. So in these countries,
higher military expenditure tends to develop more innovation; one the other hand, for countries
with fewer barriers to the weaponry market and more credit to the private sector, innovation from
military industries is more easily to be adapted for business use and the market value is more
likely to be realized. Thus, I would expect to see that if we use GNI, Industry Output, Service
Output, High-tech Exports to represent innovation, the sign of the interaction terms tend to be
positive; and if we use the number of Patents or the number of Scientific Journals to represent
innovation, the sign of the interaction terms should be negative.
!"#"$%$&!!"#$%&$'!" ∗ !!!"#$%&#'!" is controlled because I believe the level of
education affects the marginal effect of military spending on innovation. Given the same level of
R&D funding, the country that has higher education level tend to do more productive of their
research.
!"#"$%$&!!"#$%&$'!" ∗ !"#$%&!" is controlled because market efficiency also tends to
affect a country’s efficiency in generating innovation from military R&D. However, the effect of
this interaction term seems to be controversial: on one hand, in countries where market
efficiency is low (high capital threshold, high set up cost, redundant policy restriction), the
16
military provides the only possible means to develop big technology. So in these countries,
higher military expenditure tends to develop more innovation; one the other hand, for countries
with fewer barriers to the weaponry market and more credit to the private sector, innovation from
military industries is more easily to be adapted for business use and the market value is more
likely to be realized. Thus, I would expect to see that if we use GNI, Industry Output, Service
Output, High-tech Exports to represent innovation, the sign of the interaction terms tend to be
positive; and if we use the number of Patents or the number of Scientific Journals to represent
innovation, the sign of the interaction terms should be negative.

∗ !"#$%&!" + !"#$! + !"#$%&'! + !!"
�1.3�
It is also possible that the marginal effect of military spending is dependent on the level of
military spending itself. So we include the quadratic term of !!!"#"$%$&!!"#$%&$'!"! in Model
2.1. If the quadratic term is significant, there will be an optimal level of military spending. If the
increase military expenditure is still lower than the optimal level, more military expenditure
17
could increase innovation. If the increased military spending exceeds optimal level, more
investment in military sector would actually reduce innovation.

In Model 2.2, I incorporate all controls in model 1.3. So the new model tends to capture a
more precise impact of military spending on innovation. However, I may d encounter the
problem of over controlling and loose efficiency in the new model.

In addition to the basic model 1.1, I include lags of military spending in the model 3.1. This
is following the rationale that many innovations take many years to develop. Therefore, the
current innovation might be the result of some military expenditure incurred several years ago.
The exact number of lags is dependent on whether this number of lags can generate the largest
adjusted R square for the model.

DATA DESCRIPTION
A. Dataset
The dataset for this paper is drawn from the World Development Indicator (WDI) dataset
compiled by the World Bank and the Quality of Government (QOG) dataset compiled by
University of Gothenburg. The WDI data set contains country-level panel data on 214
different economies from 1960 to 2009. In order to match WDI data with the QOG data,
country groups, such as East Asia, Middle East and OECD, were removed. The WDI dataset
contains variables for up to 19 topics from Economic Policy to Social Development. The
Quality of Government dataset contains country-level data on 214 countries that existed from
1946 to 2012. Countries that collapsed were removed because their information was not
reported in the WDI dataset. The merged dataset include country-level data for159 countries
from 1989 to 2009.
B. Variables
19
The Appendix table A-1 provides variable descriptions. It explains the sources and the
meaning of the variables. The Appendix table A-2 has information about all of my descriptive
statistics.
As we can see from the table, there are six proxies for the Innovation: High-Tech Exports,
GNI, Industry output, Service output, the number of Patents, and the number of Scientific
Articles. High-Tech Exports, GNI, Industry Output and Service Output are used to approximate
the value or quality of innovation; the number of Patents and the number of Scientific Articles
are used to approximate the quantity of innovations. Since all six variables have large ranges and
variations, I use their the logged values in my model.
The independent variable of interest in this paper is military spending per soldier. We can
see that there is wide range between the highest and lowest military expenditure per soldier. The
maximum value is $1,292,440, which is about 15,368 times of the lowest value. Actually, the
$1,292,440 record belongs to Kuwait in 1990, it is no wonder that it is this high, because that
country was using all available resources in 1990 to fight against the Iraq invasion. Since there
are only 2,753 observations for the military expenditure per soldier, I have dropped all other
variables that have so few observations to make the panel dataset more balanced. Moreover,
taking out those variables will make the correlations of variables more reliable.
Moreover, the thesis also uses other important controls, including Democracy, Monetary
Freedom, Conflicts, Credit to Private Sector, Internet Users, Interest Rate Spread, Life
Expectancy for male, Internal Conflicts, Regime Quality and Tertiary Enrollment. Since the
variation and ranges for all other controls are not so large, I do not need to do log
transformations on those variables.
20
C. Correlations
The correlation table in Appendix B is the first part of my correlation table. Correlations
with an absolute value larger than 0.75 are displayed in bold italics. We can see the correlations
among the six proxies for innovation are all bigger than 0.75. This is reasonable because all these
variables are strongly related to innovation, so the correlations among them should also be strong
and positive.
We should notice that military expenditure per soldier has mild positive correlations
(around 0.4) with all innovation proxies. This suggests that an increases in military spending are
positively associated with an increases in the level of innovation.
Moreover, Tertiary (tertiary education enrollment), Credit to Private Sector, Life
Expectancy for Male, and Government Quality all have a mild and positive correlation with the
control proxies.
As for the other important controls, we can see that some have relatively strong correlations,
for example, Internet Users has a 0.6424 correlation with the Tertiary Enrollment because
countries with better infrastructure always tend to be wealthier and they can provide more
tertiary education. This should also alert us the fact that we may have multicolinearity problem,
and we should be cautious about this in the analysis stage.

EMPIRICAL RESULTS
The methodology has led us to six families of regressions. Each family uses a different type
of proxy for innovation: GNI, Industry Output, Service Output, High-Tech Output, the number
of Patent and the number of Scientific Papers. Using multiple dependent variables helps to
comprehensively capture the relationship between military spending and innovation. I use six
fixed effect models for each innovation proxy. Moreover, I use log transformation for variables
with really wide scales.
In table C-1, I choose log�GNI�to be the proxy for innovation. The first regression is a
simple fixed effect regression between log (GNI) and log (Military Spending per soldier). The
predicted coefficient is 0.238 and is significant on the 1% significance level. This indicates that
if we increase military spending per solider by 1%, the GNI will increase by 0.238%. Since I
have controlled for the fixed year and country effect, the R square has the high value of 0.82. In
Model 2, I added 7 more control variables including Democracy, Education level, Money Market
Freedom, Life Expectancy, Market Efficiency and Infrastructure on innovation. As I expected,
the Money Freedom, Market Efficiency and Infrastructure have a positive and significant effect
on the log(GNI). However, the effect of tertiary enrollment and democracy seem to have a weak
effect on GNI. In the third model, I add two interaction terms, but the result is insignificant. The
fourth and fifth models both include the quadratic term of Military expenditure. However, the
insignificant coefficients of the quadratic terms do not provide evidence that military expenditure
has a nonlinear relationship with innovation. In Model 6, I introduce lags to military expenditure
22
for 5 years and only the first lag of military expenditure is significant. However, the coefficient
of the first lag is only about one fifth the coefficient of the current year. This implies that military
expenditure will have a positive effect on GNI for two consecutive years and the effect on first
year is much larger than that of the second year. When we go through from Model 1 to Model 6,
we notice that 5 of the 6 models have predicted a positive (from 0.238 to 0.435) and significant
coefficient of log (military spending per solider). So we have reasonable grounds to believe that
increasing military expenditure is positively associated with GNI. However, we are still unsure
about the causality between military expenditure and GNI. It could also be the case that richer
countries incur higher military expenditures because they can afford expensive military
procurement and research. Benoit (1978) pointed out that there is little evidence to support the
idea that higher GNI leads to higher military expenditure. To the contrary, the military
expenditure is more likely to be determined by the political and military leaders to fulfill the
need for deterrence, threats and combat. If Benoit’s conclusions are valid, we have reasonable
grounds to believe that higher military expenditure would lead to higher GNI.
In Appendix table C-2, I take Industry Output as a proxy for innovation. Similar to the last
case, five of the six models show positive (from 0.239 to 0.666) and significant coefficient on
military expenditure. Therefore, I am confident that an increase in military expenditure is
positively associated with Industry output. In Model 3, I integrate the interaction term. Originally,
I expected that a higher civic education level would lead to higher Industry Output. However, the
term log (Military per soldier)*Tertiary enrollment has a negative and significant coefficient (-
0.00332**). This means that higher military expenditure would actually reduce the positive
effect of education on innovation. The reason might be that more military expenditure would
23
allow military to attract skilled labors from the manufacturing jobs in the private sector toward
non-production jobs such as soldiers, and scientific researchers. Looney (1992) confirmed that
there is a huge impact of military expenditure on human capital. He pointed that many
governments (especially in the Arab world) have set a high priority on attracting skilled laborers
to the military sector and there is a big competition for human capital between the military sector
and private sector. The more human capital is absorbed by the military sector, the higher
opportunity cost incurs to the private sector. Thus, there will be decreasing pressure on Industry
Output. In model 5 where I include quadratic terms and interaction terms, the coefficient on the
term log (Military expenditure per soldier)*Credit to Private Sector is also negative and
significant (-0.000984*). Since credit to the private sector is an indicator of financial market
depth, a negative coefficient means that higher military expenditure would reducing the positive
effect of financial market development on industrial output. This reinforces the expectation that
higher military expenditure would distort resources invested in the private sector and financial
market, this would further cast a downward pressure to the industrial output. In Model 6, the
coefficient of the first year lag is positive and significant. This is similar to the previous GNI
case; it means that higher military expenditure is likely to boost industry for the two following
years. However, the fourth lag has a negative and significant coefficient. This means that the
military expenditure four year ago would have a negative impact on current innovation. Since the
size of this negative is small; it is wholly dominated by the positive impact of the military
expenditure for current year and previous year.
In Appendix Table C-3, I used Service Output to proxy for innovation. The result is similar to
the previous two cases. Five of the six models show positive and significant coefficient
24
log(military expenditure per soldier). When I compare the coefficient of log(military expenditure
per soldier) in Table 2 and Table 3, I find that the coefficients in Table 2 are systematically
bigger. This shows that military based innovation has a bigger impact on second industrial
sectors (i.e. the manufacture industry) than the tertiary industrial sectors (i.e. the service
industry). The interaction terms in Table 3 are all insignificant, so the crowding out effect to
service output is not as obvious as for industry output. In Model 6, which includes lagging
military expenditure terms, I also observe that that the first-year lag has a positive and significant
effect on Service Output.
In Appendix Table C-4, all the dependent variables are Hi-Tech Export. If my hypothesis
that military spending boosts innovation is valid, I expect to see that increasing military
expenditure is associated with more high-tech exports. As I expected, the majority of the six
models (4 out of 6) show positive and significant coefficient on military expenditure. Only one
model shows negative and significant coefficient and one model shows insignificant coefficient.
In Model 5, the two interaction terms, log (Military expenditure per soldier)*Tertiary and
log(Military expenditure per soldier)*Credit to Private Sector, are negative and significant. Like
the analysis for Table 2 and Table 3, this supports the previous judgment that military
expenditure crowds out private investment. Moreover, in Model 5, the coefficient on military
spending is negative and significant; but the coefficient on squared military spending is positive
and significant. This indicates the effect of military spending on high-tech export is not linear. If
we hold other factors fixed and increase military spending fixed, the high-tech exports will
decrease at a decreasing rate; after high-tech export reach its minimum level, it will start to
increase. This suggests that as military spending crowds out investment for the private sector,
25
High-Tech Exports will be reduced, however, if a country constantly invests in the military
sector, its military industry will accumulate knowledge and expertise, and this will start to boost
high-Tech Exports. In Model 6, I include 2 lags of military expenditure. However, only the
current year military expenditure is positive and significant, while the two lags are insignificant.
In Appendix Table C-5, I use the number of Scientific Journals as proxy for innovation.
Surprisingly, none of the six models in this table predicts a significant coefficient for log military
spending. So it seemed that an increase in military spending is not associated with any change in
the number of Patents. It is very possible that the number of military related Scientific Journals is
undervalued because of the secrecy and regulation in military sector. When a country conducts
more military research, there must be more scientific papers produced. However, the government
strongly controls public access to their scientific research. Therefore, the scientific journal
figures here probably do not include military related research papers. Similar to the previous
samples, the interaction terms in Model 3, and Model 5 are negative and significant. This further
confirms that military spending would crowd out the scientific research in the private sector.
In Appendix Table C-6, log (Patent) is chosen the as proxy for innovation. The basic Model
1 indicates a negative and significant coefficient for log(military spending per soldier). The
models presents in column 2-5 all predict negative and insignificant coefficient for log(military
spending per soldier). In Model 3, the two interaction terms of log(military spending per
soldier)* Tertiary and log( military spending per soldier)* Credit to private sector are negative
and significant. Therefore, if we hold all other factors fixed, an increase in either Tertiary
enrollment or Credit to Private market will reduce the number of patent. In Model 5, the
interaction term is negative and significant again. In Model 6, the log(military expenditure per
26
soldier) itself is not significant; but the first and second lag of log(military expenditure per
soldier) is negative and significant, indicating that if we hold all other factors fixed, increasing
military spending in one year will reduce the number of patents in the second or the third year.
To conclude, four of the six proxies for innovation (GNI, Industry Output, Service Output
and High-Tech Exports) are positively related to military expenditure. Since these four variables
can be used to measure the quality and value of innovation, I am confident that military
expenditure leads to innovation, which brings a lot of economic benefits to society. As for the
proxy of Patents and the number of Scientific Journals, they seem not to be associated with any
change of military expenditure. I believe that this is because military data and records are critical
to the national security, so the government intentionally conceals them. If Patents and the
Scientific Articles include the true military related Patents and Scientific Articles, they should
also be positively related to the military expenditure. Therefore, the hypothesis that military

expenditure can boost innovation should be justified based on all evidences from my regression
analysis.
LIMITATIONS AND CHALLENGES
Similar to the exiting studies in this area, this thesis is also subject to some degree of
measurement errors. According to the Oslo Manual, (2005, p46) “an innovation is the
implementation of a new or significantly improved product (good or service), or process, a new
marketing method, or a new organizational method in business practices, workplace organization
or external relations”. Although it is easy to define innovation, it is very hard to measure it. An
increase in innovation can happen in both the qualitative and quantitative dimensions (more
technologies and ideas vs better technologies and ideas).
In Jacob’s (2008) and Willen’s (2013) studies, innovation is only measured by the number
of Patents. Technically, the number of Patents is a good measure of the quantity of new ideas.
But it has many drawbacks: First, different countries may follow different standards and criteria
for deciding whether a new idea be registered with a patent. Second, patents give the same
weight to all new ideas and fail to evaluate their quality. Third, patents fail to account for non-
technology innovations such as new processes, organization systems, or marketing methods.
Clearly, it is difficult to have a precise measure of innovation for research purpose. However, an
even harder topic is to capture the military related innovation.
28
As we know, military innovations are primarily used for military purposes. According to
Eleazar (2010), military innovations happen in five dimensions: “maneuver, doctrine, training,
combined-arms fighting, and defensive technology” Eleazar (2010:11). For example, a new
method of training is a military innovation. It promotes the efficiency and effectiveness of the
army, and reduces casualties and other losses in the future. However, it is difficult to establish a
common standard to measure the value of the improving efficiency and effectiveness. Also, if
this training method reduces the number of casualties, it is hard to estimate its corresponding
economic value because lives are priceless and we cannot give a price to lives. Similarly, it is
also hard to estimate the economic value of better security of the nation. Also, some military
innovation is critical to maintain the security of the country. Unfortunately, all previous studies
fail to account for the value of military innovation for national security purpose.
Furthermore, it is difficult to fully capture the value of military innovation for
commercial purpose. To estimate the dollar value of military innovations, we need to solve two
problems: 1. In an efficient market, the value will be calculated as the net present value of the
increase of future cash flow. If we take the innovation of the Internet or GPS as an example, the
creations of these technologies bring major breakthroughs to human society and create trillion-
dollar markets. However, it is impossible to approximate the value of these technologies in early
stages, because we have no idea about how people in the future utilize the early technologies.
More specifically, if there is no Internet, there will be no Google or Amazon. But people did not
incorporate the value of Google or Amazon into the value evaluation of Internet when it is just
invented. Therefore, it is impossible to discover and value all the benefits from innovation. 2.
The value of military innovation to the market does not merely depend upon the quality of
29
innovation itself, but also upon many other factors such as the market efficiency, policy
constraints, and time. Bronwyn (2011) suggests that productivity growth and GDP are good
proxies for innovation because they constantly reflect the market value of innovation. However,
the same military innovation could have different monetary values simply because different
countries have different capacities to adapt the innovation for business use.
Therefore, due to the measurement error, all proxies for innovation cannot give a full
picture of the military based innovations and we believe the levels of innovation are largely
undervalued. In my thesis, even though I have used multiple proxies to measure innovation, but
the measurement error still exists. Since this bias is a downward bias, we believe the true impact
of military expenditure on innovation should be even larger.
POLICY IMPLICATIONS
In the previous session, I have used six different proxies for innovations and conducted
series of fixed effect models to test the hypothesis that military expenditure can boost innovation.
As I have expected, the regression models have shown concrete evidences supporting the idea
that increased military expenditure can lead to higher levels of innovation. Based on these
findings, policymakers should have a new understanding of their defense budgets and take
measures to adjust the policy accordingly. The new policies should strengthen the investment in
the military innovation, elevate the quality of military innovation, and assist the value realization
30
of the military innovation. Therefore, I would suggest the policy implications from four different
perspectives.
The first implication is that governments should reevaluate the impacts of military
innovation and optimize their military expenditure accordingly. According to the Stockholm
International Peace Research Institute (Bodell, 2013), countries like United States (4.4%), Russia
(4.4%) and Saudi Arabia (8.9%) have very high military spending as percentage of GDP. The
United States and Russia are well known as the top-two winners in the world weaponry market,
and they both have advanced military technologies. Saudi Arabia is not very productive in
military innovation even though it spends too much money on the military sector. This is because
Saudi Arabia buys excessive amounts of weaponry from the United States and uses its military
purchasing policy as tool to strength the bilateral relationship between Saudi Arabia and America.
Had this country tried to replace the weaponry input with domestic research and manufacturing,
we would expect to see more military innovation from Saudi Arabia. Countries like China (2%),
Japan (1%), Germany (1.4%) and Brazil (1.5%), have relatively low military spending as
percentage of GDP (Bodell, 2013). Since Military Spending would boost innovation, these
countries may undervalue the positive impacts of increasing military expenditure. So countries
like China, Japan and Germany should carefully reevaluate their military expenditure and decide
whether to increase their defense budgets and harvest the subsequent military innovation.
However, boosting innovation is not the sole or most important purpose for increasing military
spending. In the real world, there are many reasons for a country to increase its defense budget.
For example, a country may need more defense budget to maintain internal stability, protect the
boarders, and fight natural disasters. So when these countries decide whether to increase military
31
expenditure, they need to balance many different concerns, rather than merely focus on the need
for extra military innovations.
Second, Governments should restructure the military budget and devote more resources
to military research and development. Since most of the military innovation and new
technologies come from the military labs and research centers, boosting effects of military
spending on innovation has to work through military R&D programs. If the government is
concerned about boosting innovation from the military sector, it is better for them to restructure
the defense budget and directly increase investment in military R&D programs. In recent decades,
countries like India and Israel have put a lot of effort into promoting their military
industrialization, which helps them maintain strong regional power and brings huge economic
benefits (Hoyt, 2007)
Third, Countries should increase mutual trust with their neighbors and cooperate in
military R&D. Due to the long time span and high fixed cost, many countries are not able to
design and produce the weaponry on their own. To overcome this problem, countries could
cooperate in the military R&D projects with their neighboring countries. This kind of
cooperation would greatly increase mutual trust and promote regional peace. Moreover,
countries would share the cost and risk of making military R&D investments. There are many
great examples for this kind of international cooperation. For example, the Eurofighter Typhoon
is a advanced fighter jet project developed by UK (33%), Germany(33%), Italy(21%) and
Spain(12%). Each country committed experts and capital into the project and the partnership and
they maintain a long-lasting political and industrial relation” (Benien, 2013). Right now, these
32
four nations not only purchase the Eurofighters for their own air forces, but also export the jets to
countries like Saudi Arabia, Australia, and Canada.
Fourth, Governments should increase the mobility between the military sector and private
sector in terms of human capital, ideas and capital. In many countries, the military has
accumulated advanced innovations from their R&D projects. However, due to the barriers
between the military sector and private sector, a great number of those valuable technologies and
ideas are hidden in the research centers of weaponry suppliers. If governments can build a
channel that allows the military sector and the private sector to share knowledge, capital and all
other resources, the nation will gain substantial benefit from higher productivity and stronger
economic growth.
Technically, the channel should address three different perspectives. The first is the
exchange and communication of technologies and ideas. It means that governments should
encourage communication and cooperation among military manufactures and scientific centers,
encouraging them to work together with the competitive and trustworthy private corporations. If
both the military and the private counterparties are interested in the transfer of certain
technologies and these technologies can truly serve the public interest, government should
facilitate these transfers under careful review and supervision. A good example is the private
Chinese company, Beidou Navigation Service Company (Zheng, 2014), which closely
cooperates with the Chinese military to promote the newly developed Chinese navigation
system- Beidou.
The second dimension is the mobility of human resources. This means that government
should allow some military experts and scientists to join private corporations and research
33
centers. The experts and scientists in the military sector have developed special experience and
expertise from their previous research. If the government can allow some of them to work and
cooperate with private companies, those experts would facilitate the transfer of military
technologies or bring some new innovations.
The third dimension is to encourage private capital to enter the military sector by listing
weaponry manufacturers in the financial markets. The government can choose have the option of
retaining shares in the newly listed firm or fully privatizing the firm. In both cases, the military
manufacturers are able to attract private investment and therefore have more capacity to initiate
new research and projects. In return, the public would demand more disclosure and transparency
from those listed military companies. Their managers would be forced to improve the
performance of the listed weaponry corporation through investing in more productive projects,
optimize the corporation structures, reduce the fraud and cost, and improve efficiency and
productivity. If the managers work hard and earn good profits for the stakeholders, they will be
rewarded with bonus options and promotions; If they shirk the job and generate poor
performance, they might be fired and it would be hard for them to get another job in a well
informed market. In the western world, there are many well-known weaponry companies already
listed in the financial market, for example, the Lockheed Martin Corporation and the Raytheon
Company. These companies are very successful and they provide America with advanced
military equipment. In the last decades, the Chinese government set these successful defense
companies as a good example and has been endeavoring to transfer the national defense
companies to public listing company. The government believed that this procedure would help
34
the defense companies to construct a modern management system, accept social supervision, and
address investments in both the military and civilian sectors (Sun, 2007).
Certainly, to apply military technologies in the private sector would be beneficial to a
country’s economic growth, but it also involves some costs. The biggest concern is that the
valuable and confidential technologies would be leaked to the country’s enemies or competitors.
As the military department has devoted massive resources to the military technologies, their
primary goal is to keep strategically advantage over enemies and competitors. Leaking key
technologies would make the country lose its previous strategic advantage. Therefore, the
country should carefully evaluate the potential gain from the transfer of that technology, and the
potential risk of leaking that technology to enemies. If the net benefit is significant and the
country is confident about protecting its core secrets, then it should be a good idea to support the
technology transfer.
Technically, if a country can establish an effective system to manage and minimize the
risk from connecting the military sector and the private sector, that country will derive the
greatest value from its innovation. Therefore, devising and constructing such a risk management
system should be an import topic for future policy research.
Referring to the previous quotation from Eisenhower, all investments in the military
sector come from savings of other sectors. Therefore, policymakers have responsibilities to
spend the taxpayers’ money wisely. Since investments in the military sectors are always billion-
dollar projects, both overinvestment and underinvestment could cause huge losses to the society
at large. So before we decide to make a change to our defense budget, it is very important to
understand the true impacts of such changes. However, due to the lack of data and military
35
privacy policy, most of the existing research might have a biased estimation about impacts of
military expenditure. Therefore, Governments should utilize their internal resources to conduct
more advanced research to discover the true impacts of military expenditure. Only in this way
can the governments implement good defense policies and discharge their responsibilities to
society.
