摘要：West Bengal potato farmers cannot directly access wholesale markets and do not knowwholesale prices. Local middlemen earn large margins; pass-through from wholesale to farmgate prices is negligible. When we informed farmers in randomly chosen villages about wholesale prices, average farmgate sales and prices were unaffected, but pass-through to farmgate prices increased. These results can be explained by a model where farmers bargain ex post with village middlemen, with the outside option of s...

摘要：We propose that individuals are more politically active in more like-minded social environments. To test this hypothesis, we combine administrative data from the Federal Election Commission and the U.S. Postal Service. We identify 45,000 individuals who contributed to Barack Obama's 2008 presidential campaign and changed residences either before or after the 2012 election cycle.We examine whether living in an area with a higher share of Democrats causes higher contributions to Obama. We find t...

摘要：We examine the housing market and residential mobility changes that occur soon after a Title 1 school fails to achieve adequate yearly progress (AYP) in Charlotte, North Carolina. Students within attendance zones of failing schools are given priority in lotteries for oversubscribed schools, potentially increasing the attractiveness of living in a failing school attendance zone. We find that housing prices, home buyer income, and the probability of attending a nonassigned school increase in the...

摘要：How big is the elasticity of substitution between goods from different countriesthe Armington elasticity? Estimates of the macroelasticity between home and imported goods are often smaller than the microelasticity between foreign sources of imports. Using new, highly disaggregate U.S. production data matched to imports and simulated data from a Melitz-style model with nested CES preferences, we explore estimation techniques for the two elasticities. For between two-thirds and three-quarters of...

摘要：We introduce a test of the rank invariance or rank similarity assumption common in treatment effects and instrumental variables models. The test probes the implication that the conditional distribution of ranks should be identical across treatment states using a regression-based test statistic. We apply the test to data from the Tennessee STAR class-size reduction experiment and show that systematic slippages in rank can be important statistically and economically.
