Government purchases represent a big fraction of World’s GDP
- 11-20% depending on country and year
- Governments are the largest buyers in many industries
- Potentially powerful industrial policy tool
Development/macroeconomic implications not well understood

IntroductionLocal share of procurement across French and Spanish regions
Share of procurement value
awarded to plants located
within the same region
Around 53% on average
Compares to 32% for total trade
Not driven by composition
– Machinery and elec. equip.: 50% vs. 37%
– Transport equipment: 41% vs. 19%
– Food: 78% vs. 27%

IntroductionRelevant questions
Are governments responsible in explaining these patterns?
* Challenge: potentially driven by two types of origin-destination factors:
1. Natural frictions: τod abruptly increases when o ≠ d
- ex: geography, information frictions, path dependence, etc.
2. Governments’ home-bias
- governments intentionally discriminate against non-local firms
- Joe Biden: “we will not purchase anything that is not made in America”, Sep. 2020
- increasing cross-border participation is one of the EU Commission’s main goals
What are the consequences for aggregate efficiency and welfare? (not today)
* It benefits local firms
* Inefficient provision of public goods

Introduction Data The role of governments: a simple decomposition Plant-level evidence Model Quantification Conclusions
IntroductionThis paper
1. Dataset of procurement contracts awarded in Spain and France
- more than 1 million contracts in 38 regions
- info about the contract: value, product, etc.
- info about the seller: location, firm, etc.
- info about the buyer: location, agency (around 10,000 only in Spain!), etc.
→ key: classify buyers into different gov. types
2. New plant-level evidence on inter-regional and international procurement flows
- participation increases systematically with market size
- sales distributions are similar across markets
- big “border effects” both at the region and country level

3. Strategy to identify the role of governments in explaining these border effects
– Sub-national vs. national governments have offices in the same location
- Ex: both the Federal Gov. and the Gov. of California have offices in San Francisco
- Ex: both the central Spanish Gov. and the Catalan Gov. have offices in Barcelona
– Use variation within a plant-origin-destination across government-types
- Allows us to control for τod!
– Hypothesis: geographical scope of governments main driver of home bias
- Regional governments discriminate against firms from other regions
- National governments discriminate against firms from other countries
4. Quantitative exercise
– Multi-region trade model with heterogeneous firms applied to procurement
- Chaney (2008), Breinlich, Cunat (2014)
– Use the model to quantify the aggregate effects of governments’ home bias

Data
Introduction Data The role of governments: a simple decomposition Plant-level evidence Model Quantification Conclusions
Procurement DataOur sample (all EU countries potentially)
We worked with France and Spain so far
Classify “buyers” into different gov. types
1. LOCAL: 18.56 %2. PROVINCIAL: 16.13 %3. REGIONAL: 23.58 %4. NATIONAL: 41.71 %
Work with 2 government types: national and sub-national
Big overlap in purchases across governments
- ex, motor vehicles: sub-national spend e5M and national spend e2M
- ex, medical consumables: sub-national spend e14M and national spend e5M
Years: 2011-2019
Plants: 192,155

Plant-level evidence
Introduction Data The role of governments: a simple decomposition Plant-level evidence Model Quantification Conclusions
Plant-level evidenceThree stylized facts about procurement
1 Firms’ participation in procurement increases with market size, BUT
1.a Firms participate disproportionally more in their own country
1.b Within their country, firms participate disproportionally more in their own region
1.c This last pattern particularly strong for sub-national governments
2 The firms’ sales distribution within an origin o is similar across destinations
2.a Well approximated by a Pareto except for the very low end of the distribution.

Shipping goods across regions is costly (τor)
Each region is populated by Lr consumers who supply one unit of labor
Heterogeneous firms produce tradable differentiated intermediate goods

Conclusions
Introduction Data The role of governments: a simple decomposition Plant-level evidence Model Quantification Conclusions
Conclusions and final discussion
Governments’ actions crucial to explain low penetration rates in procurement
What are the factors driving these actions?
– Consumers have preferences for local goods
- Morey, 2016
– Protectionism:
- Political economy determinants (Grossman, Helpman, 1994)
