This paper studies the optimal design of rules in a dynamic model when there is a time inconsistency problem and uncertainty about whether the policy maker can commit to follow the rule ex post. The policy maker can either be a commitment type, which can always commit to follow rules, or an...

The Frank-Wolfe algorithm is a simple projection-free algorithm for constrained optimization, and it has been successfully applied to a variety of real-world problems. Its main drawback however lies in its speed of convergence, which can be excessively slow due to naive descent directions. In this...

Did mobile Internet contribute to the rise of populist, anti-elitist and non-traditional parties across Europe? In this paper, we use a combination of highly geographically disaggregated data on the spread of 3G and 4G mobile Internet in 22 countries in Europe since 2007, administrative data on...

We study inference in complete information games with discrete strategy spaces. Unlike binary games, we allow for rich strategy spaces and we only assume that they are ordinal in nature. We derive observable implications of equilibrium play under mild shape restrictions on payoff functions, and we...

Supply chain disturbances can lead to important increases in production costs. When looking for new suppliers, firms therefore worry about the risks associated with potential trading partners. We investigate the impact of beliefs and uncertainty on the structure of the production network and,...

This paper develops and estimates an elegant equilibrium business cycle model. The framework is consistent both with micro-evidence regarding the distribution of growth rates across firms and macro-evidence on gross job creation and job destruction flows over the cycle. By also incorporating on-the...

Anti-personnel landmines are one of the main causes of civilian victimization in conflict-affected areas and a significant obstacle for post-war reconstruction. Demining campaigns are therefore a promising policy instrument to promote long-term development. We argue that the economic and social...

« Economists routinely make functional form assumptions about consumer demand to obtain welfare estimates—often for convenience, tractability, or both. How sensitive are welfare estimates to these assumptions? In this paper, we answer this question by providing bounds on welfare that hold for...
