A notable feature of post-World War II civil wars is their very long average duration. We provide a theory of the persistence of civil wars. The civilian government can successfully defeat rebellious factions only by creating a relatively strong army. In weakly-institutionalized polities this...

Economic theory predicts that military conscription is associated with static inefficiencies as well as with dynamic distortions of the accumulation of human and physical capital. Relative to an economy with an all-volunteer force, output levels and growth rates should be lower in countries that...

We build a model of conflict in which two groups contest a resource and must decide on the optimal allocation of labor between fighting and productive activities. In this setting, a diaspora emanating from one of the two groups can get actively involved in the conflict by transferring financial...

Military service is an important vehicle through which young Americans invest in their human capital. Using internal military data, we show that county-level exposure to U.S. combat casualties during the Iraq and Afghanistan wars decreased the supply of new soldiers in that county, and changed...

We provide quantitative evidence on the relationship between military spending and innovation in the 19th century. Combining innovation data from world fairs and historical military data across Europe, we show that national military spending is associated with national innovation towards war...

Though in decline recently, military conscription is still a widely used mode of staffing armies. Since not many valid economic, social or military arguments in favor of the draft can be put forward, the question emerges why societies choose to rely on it. In this survey we explain the political...

We examine the interaction between foreign aid and binding borrowing constraint for a recipient country. We also analyze how these two instruments affect economic growth via non-linear relationships. First of all, we develop a two-country, two-period trade-theoretic model to develop testable...

Various development objectives are worthy, but to my mind, one objective dominates all others: reducing the scourge of absolute economic misery in the world. In this paper, I focus on an important but relatively underemphasized approach to poverty reduction: helping the poor earn more in the...

We investigate whether estimates of the effect of aid on growth are influenced by authors' careers. We collect data on the careers of 190 authors and apply meta-regression analysis to investigate the impact of authors' age and tenure status on the reported magnitude of aid effectiveness, and on...

Students from low-income families are eligible to student aid under the federal students' financial assistance scheme (BAfoeG) in Germany. We evaluate the effectiveness of a recent reform of student aid that substantially increased the amount received by eligible students to raise enrolment...
