The Economic Causes and Consequences of

Conflict:

Where the literature stands and where we should go from here

EITM Lecture – PART 2

Prof. Oeindrila Dube

Aid and conflict

Discussion:

• What are potential theoretical channels through which aid may affect conflict?

Aid

Theoretical channels

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

Challenge to Identification

• 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

Aid under Fire: Development Projects and

Civil Conflict

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

Feeding Conflict:

The Unitended Consequences of U.S. Food

Aid on Civil War

Qian and Nunn (2011)

Overview

• 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

Potential mechanisms

• Increased value of the state

• Diversion of food aid to armed groups

• Alternative mechanism: price effects?

Evidence of military aid diversion

(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

3. The Economic Consequences of Conflict

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

Profiting from conflict

• 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)

Stock market returns and Savimbi’s death

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

Taking stock

• 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

Way forward on examining economic consequences of conflict

• 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
