• What are potential theoretical channels through which aid may affect conflict?
Aid
Economic benefits lower grievances/ raise opportunity cost of fighting
State stronger
More gains from predation
Leakage or mistargeting
Less conflict
Less conflict
More conflict
More conflict
• Selection
– Aid allocated toward good performers upward bias
– Aid allocated toward “basket cases” downward bias
Aiding Violence or Peace?
(De Ree and Nillesen, 2009)
• Does development aid affect likelihood of conflict?
– In Sub-Saharan Africa
• Empirical strategy:
– Instrument for aid flow using average donor country GDP
• Results
– Aid reduces the duration of conflict
– Aid has no significant effect on probability of conflict onset
Crost and Johnston (2010)
Overview
• Does participation in major community driven development program affect violence?
• Within country analysis
– Philippines, 2003-2008
• Regression discontinuity design
– Within each province poorest 25% of municipalities eligible for a major community driven development program
– Running variable: distance of poverty ranking from eligibility threshold
Qian and Nunn (2011)
• What is the effect of U.S. wheat aid on conflict?
– 121 recipient countries, over 1967 – 2004
• Empirical strategy
– Instrument U.S. wheat aid with weather in conditions in U.S. wheat producing regions
– Interact wheat aid with average probability country receives food aid
Second-stage
First-stage
2SLS estimates of the effect of U.S. Wheat Aid on the Probability of Conflict
• Increased value of the state
• Diversion of food aid to armed groups
• Alternative mechanism: price effects?
(Dube and Naidu, 2010)
• Rise in U.S. military found to increase paramilitary violence in Colombia
• Consistent with diversion since
– U.S. military aid goes to the Colombian military, which is stationed in regions with bases
– U.S. military aid leads to more attacks in base regions by paramilitary groups (aligned with the Colombian military)
– No equivalent increase in attacks by guerilla groups
Taking stock of the aid-conflict literature
• Mixed results
– Opposite effects of development aid within vs. across country
– Food and military aid found to increase conflict
• Little on understanding why
– Conflict reducing effects: opportunity cost vs. state capacity?
– Conflict promoting effects: diversion, prize, strategic reasons?
• Different effects based on aid type?
– Government, foreign govt./military, NGO disbursement
– Project vs. program aid
Several recent papers show null effects
• No effect of civil war on consumption, school enrollment or nutrition in Sierra Leone (Bellows and Miguel, 2006 and 2009)
– Higher participation in collective action and political participation
• No effect of bombings on long run poverty in Vietnam
(Miguel and Roland , 2010)
Compared to non-bombed areas, bombed areas did
NOT have lower…
• Local poverty rates
• Consumption levels
• Infrastructure
• Literacy
• Population density
Doesn’t necessarily imply war was economically inconsequential
• Compares districts within Vietnam
– National growth rate may have been faster in the absence of war
– Government investment/foreign aid could have gone to other, non-bombed regions
• Private foreign investment may have been greater if it were not a post-conflict country
• Event study methodology to show beneficial effects of conflict on firms
• Stock returns of partly nationalized corporations increased during covert coups (Dube, Kaplan and Naidu, forthcoming)
• Diamond company stock returns declined with end of
Angolan civil war (Guidolin and La Ferrara, 2008)
What “benefits” did war confer to diamond companies?
• Entry barriers for other diamond companies were higher
• Bargaining power of Angolan government lower
– Licensing and rent-seeking costs for incumbent firms lower
• Lower transparency standards permitted more profitable dealings
• Micro results point to interesting compositional effects
• Micro data may not enable us to capture net effects of conflict on economic performance
– Counterfactual hard to establish with cross-regional comparisons
– Firm event studies are essentially case studies
• Literature lacks an identified cross-country analysis of how conflict affects economic performance
– Large returns to having the first good instrument
• More interesting to show conditions under which there are positive and negative effects
– For within or cross-country analysis
– Particularly since micro studies show both effects possible
