constraining the gasoline and diesel supply chains. We consider several factors that alter the elasticity of supply, including … variation in the demand for untaxed uses of diesel. In general, we find that in periods of time when the supply chain is … supply disruptions such as after major hurricanes …

Using an IV strategy based on an equilibrium model of fish supply that exploits time-series variation in oceanic SST …We exploit variation in the composition of local fish catches around the time of birth using administrative and census … the causal effects of early-life consumption of methylmercury (MeHg) and DHA, elements contained in fish, on cognitive …

We estimate a dynamic profit-maximization model of a fish wholesaler who can observe consumer characteristics, set … individual prices, and thus engage in third-degree price discrimination. Simulated prices and quantities from the model exhibit … the key features observed in a set of high quality transaction-level data on fish sales collected at the Fulton fish …
