Recent literature has emphasized the importance of transport costs and infrastructure in explaining trade, access to markets, and increases in per capita income. For most Latin American countries, transport costs are a greater barrier to U.S. markets than import tariffs. We investigate the...

There are many industries in which potentially competitive segments require services provided by natural monopoly bottlenecks (essential facilities). Since it is difficult to regulate these facilities, developing countries are using Demsetz auctions, where the facility is awarded to the firm...

Transportation infrastructure is vital for the smooth functioning of international trade. Ports are a crucial gateway to this system: with more than 80% of trade carried by ships, they shape trade costs, and it is critical that they operate efficiently. Yet ports are susceptible to disruptions,...

We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated, however, by endogenous city formation and "wave interference" that we show in simulations. We use the locations of...

This paper discusses the recent changes in the market for catastrophe risk. These risks have traditionally been distributed through the insurance and reinsurance systems. However, because insurance companies tend to share relatively small amounts of their cat exposures and because insurance...

This paper examines the market for catastrophe event risk -- i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. This market is in transition as new approaches for transferring risk are being explored. The paper studies several...

The impacts of environmental change on human outcomes often depend on local exposures and behavioral responses that are challenging to observe with traditional administrative or sensor data. We show how data from private pollution sensors, cell phones, social media posts, and internet search...

COVID-19 has demonstrated the challenges that policymakers, insurers, businesses, and employees face when disaster assistance programs are developed after the pandemic has already started. There is now an opportunity to design and implement effective and efficient solutions to manage the...

This paper describes the design and analysis of a web-based choice experiment that examines how the demand for earthquake protection in Quebec and British Columbia is influenced by the default option and the structure of the insurance plan. Homeowners in both provinces were given the opportunity...

Farmers have higher rates of disability and illness than the general population and more volatile incomes due to frequent crop and livestock losses from extreme weather events. This raises concerns that sudden, weather-related drops in farm income could reduce access to health care for an...
