摘要：We study the effect of elementary school teachers' beliefs about gender roles on student achievement. We exploit a natural experiment where teachers are prevented from self-selecting into schools, and, conditional on school, students are allocated to teachers randomly.

The uncertainty measures reflect changes in both the conditional mean and volatility of the variables, and their impact on the economy can be assessed within the same framework. Estimates with U.S. data show substantial commonality in uncertainty, with sizable effects of ...

摘要：Using data on women's choice of hospital for childbirth in Florida, we find that women return to the same hospital approximately 70% of the time. We separate explanations of switching costs and unobserved preference heterogeneity using a panel data fixed effects estimator and find that switching costs account for approximately 40% of the demand effects of a lagged dependent variable. The welfare effects of excluding a hospital from a payer's network are smaller in the short run but higher in t...
