We propose an immigration policy based on the model of cooperatives. Incoming migrants have to acquire a participation certificate. In exchange, the immigrants may enter the country of choice without danger. The revenue goes to the country of the recipient nation rather than to human smugglers....

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...

After World War II, town twinning became popular, notably in Germany. This was mainly a reaction to the war experience, and it was aimed at creating renewed international understanding and co-operation between German cities and cities in other countries. The contacts created by town twinning...

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...

Over the past 70 years, the number of international environmental agreements (IEAs) has increased substantially, highlighting their prominent role in environmental governance. This paper applies the toolkit of network analysis to identify the network properties of international environmental...

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...

China's development model challenges the approaches of traditional Western donors like the World Bank. We argue that both aim at stability, but differ in the norms propagated to achieve that. Using fixed effects and IV estimations, we analyze a broad range of subnational stability measures in...

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...
