Our experimental analysis of alliances in conflicts leads to three main findings. First, even in the absence of repeated interaction, direct contact or communication, free-riding among alliance members is far less pronounced than what would be expected from non-cooperative theory. Second, this...

Recent international climate negotiations suggest that complete agreements are unlikely to materialize. Instead, partial cooperation between like-minded countries appears a more likely outcome. In this paper we analyze the effects of such partial cooperation between like-minded countries. In...

This paper analyzes the setting of national patent policies in the global economy. In the standard model with free trade and social-welfare-maximizing governments à la Grossman and Lai (2004), cross-border positive policy externalities induce individual countries to select patent strengths that...

This paper empirically studies the impact of decentralization on foreign aid effectiveness. For this purpose, we examine a commonly used empirical growth model, considering aid modality as well as different measures of political and fiscal decentralization. Our panel estimations reveal that...

Using data from 1988 to 2007, we examine to what extent bilateral aid flows of an individual donor to a country depend on aid flows from all other bilateral and multilateral donors to that country. We thereby want to assess to what extent donor coordination, free-riding, selectivity,...

Empirical evidence suggests that money in the hands of mothers (as opposed to fathers) increases expenditures on children. From this, should we infer that targeting transfers to women is good economic policy? In this paper, we develop a non-cooperative model of household decision making to...

This paper studies the effects of bilateral foreign aid on conflict escalation and de-escalation. We make three major contributions. First, we combine data on civil wars with data on low level conflicts in a new ordinal measure capturing the two-sided and multifaceted nature of conflict. Second,...

In this paper, foreign aid transfers can distort individual incentives, and hence hurt growth, by encouraging rent-seeking as opposed to productive activities. We construct a model of a small growing open economy that distinguishes two effects from foreign transfers: (i) a direct positive...
