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...

We present a new mechanism to explain politically induced changes in bilateral aid. We argue that shifts in the foreign policy alignment between a donor and a recipient country arising from leadership changes induce reallocation of development aid. Utilizing data from the G7 and 133 developing...

Since the introduction of the HIPC Initiative in the early 2000s, indebted LICs had to show a decent governance performance before their debts were forgiven. We discuss the hypothesis that during the follow-up, Multilateral Debt Relief Initiative (MDRI), the World Bank has refrained from this...

This paper examines whether the federal structure of aid-receiving countries matters in explaining aid effectiveness. Following the decentralization theorem, the devolution of powers should increase aid effectiveness, since local decision-makers are better informed about local needs. At the same...

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...

We use an excludable instrument to test the effect of foreign aid on economic growth in a sample of 96 recipient countries over the 1974-2009 period. We interact donor government fractionalization with a recipient country's probability of receiving aid. The results show that fractionalization...

We examine how donor government ideology influences the composition of foreign aid flows. We use data for 23 OECD countries over the period 1960]2009 and distinguish between multilateral and bilateral aid, grants and loans, recipient characteristics such as income and political institutions,...
