March 2018A Swing-State Theorem, with Evidence
with John McLaren: w24425
We study the effects of local partisanship in a model of electoral competition. Voters care about policy, but they also care about the identity of the party in power. These party preferences vary from person to person, but they are also correlated within each state. As a result, most states are biased toward one party or the other (in popular parlance, most states are either ‘red’ or ‘blue’). We show that, under a large portion of the parameter space, electoral competition leads to maximization of welfare with an extra weight on citizens of the ‘swing state:’ the one that is not biased toward either party. The theory applies to all areas of policy, but since import tariffs are well-measured they allow a clean test. We show empirically that the US tariff structure is systematically biased ...
December 2011Export Prices of U.S. Firms
with James Harrigan, Victor Shlychkov: w17706
Using confidential firm-level data from the United States in 2002, we show that exporting firms charge prices for narrowly defined goods that differ substantially with the characteristics of firms and export markets. We control for selection into export markets using a three-stage estimator. We have three main results. First, we find that highly productive and skill-intensive firms charge higher prices, while capital-intensive firms charge lower prices. Second, U.S. firms charge slightly higher prices to larger and richer markets, and substantially higher prices to markets other than Canada and Mexico. Third, the correlation between distance and product-level export prices is largely due to a composition effect.
