We examine the welfare-based opportunity cost of foreign exchange (FX) intervention when both CIP and UIP deviations are present. We consider a small open economy that receives international capital flows through constrained international financial intermediaries. Deviations from CIP come from...

Cumulative culture is a cornerstone of human intelligence. Currently, two models give contrasting explanations of how it works. According to one, humans build causal models and innovate by reasoning over them; culture acts as a repository of these accomplishments. According to another, humans...

We consider the problem of aggregating individual preferences over alternatives into a social ranking. A key feature of the problems that we consider—and the one that allows us to obtain positive results, in contrast to negative results such as Arrow’s Impossibility Theorem—is that the alternatives...

We develop a theory of optimal security design for financing green investments in the presence of greenwashing. Green outcomes are uncertain and can be obtained through the implementation of tangible projects and/or intangible effort-based strategies. When manipulation is not possible, the optimal...

Adaptation to environmental change can carry negative externalities. We document one such case: farmers in California respond to heat and drought by extracting more groundwater, harming access to drinking water for nearby residents. Using yearly variation we show that surface water scarcity and...

This paper develops a framework for embedding carbon pricing policies into existing international trade agreements, which have historically evolved without consideration for climate change. Using a model of international trade with input-output linkages that incorporate detailed fossil fuel energy...

In this paper we study an alternative approach to reduce the expansion of criminal organizations: preventing gang recruitment at schools, where criminal organizations commonly target children. To do so, we exploit the staggered implementation of a preventive program in El Salvador that increased...

Propagation of chaos is a phenomenon according to which, in a system of N interacting particles, two given particles become « more and more » independent as N goes to infinity. Proving such a phenomenon, with hopefully a quantitative rate, allows one to boil down the study of large systems of...

We examine the empirical content of matching models of the labor market in which firms and work- ers are ex ante heterogeneous in the presence of symmetric uncertainty and learning about worker ability and human capital acquisition by workers. We allow ability and acquired human capital to be...

Platform-run marketplaces may exploit third-party sellers’ data to develop competing products but the threat of future competition can deter sellers’ entry. We explore how this trade-off affects the platform’s entry on the marketplace and the referral fee it charges to the third-party sellers. We...
