The street food market is a major source of food in developing countries, but is often characterized by unsafe food conditions. We investigate whether improvements in food safety can be achieved by providing information to vendors in the form of a training. Among randomly assigned groups of...

The community in which a child is raised has a substantial effect on their income in adulthood. To help understand what is different about communities which produce higher incomes, we document how time use differs between communities which increase vs. decrease incomes. The main differences are...

There are several locations, each of which is endowed with a resource that is specific to that location. Examples include coastal fisheries, oil fields, etc. Each agent will go to a single location and harvest some of the resource there. Several agents may go to each location. We assign...

There is a divisible commodity and money. Each agent has an endowment of the two goods and continuous, monotone, convex preferences over bundles. Agents may benefit from trade. An exchange rule is a mapping that, for each profile of preferences, calculates for each agent a trade that he finds...

We identify a large subdomain, D, of quasilinear economies on which any efficient exchange rule will be generically (in the Baire sense) manipulable. For generic economies outside of D, we find rules that are locally non-manipulable. The interior of the set D consists of all economies in which...

We consider taxation of exchanges among a set of agents where each agent owns one object. Agents may have different valuations for the objects and they need to pay taxes for exchanges. We show that if a rule satisfies individual rationality, strategyproofness, constrained efficiency, weak...

This paper estimates the impacts of religiosity on criminal activity using a city-wide shock to religious sentiment from a 2015 Papal visit. Using daily data on all reported offences between 2010 and 2015 in Philadelphia at the census tract level and a difference-in-differences approach, we...

How does exposure to Islamist terrorism change perceptions of the share of Muslims and immigrants? We conduct a large-scale survey that measures misperceptions towards minority groups in four European countries. Our results show that terror attacks in the past increased misperceptions of the...
