摘要：Taller workers receive a wage premium. Net of differences in family background, the disparity is similar in magnitude to the race and gender gaps. We exploit variation in an individual's height over time to explore how height affects wages. Controlling for teen height essentially eliminates the effect of adult height on wages for white men. The teen height premium is not explained by differences in resources or endowments. The teen height premium is partially mediated through participation in ...

摘要：I show that among women likely to use welfare, movers move to higher-benefit states. I also find that the probability likely welfare users will move at all is lower in higher-benefit states. This effect is concentrated early in the life cycle, as theory predicts. I construct a theoretical framework to measure the impact of welfare migration on optimal state benefits. Simulation results suggest little impact in higher-benefit states, but possibly a more substantial impact in other states. Final...

摘要：We develop a parsimonious model of innovation to confront firm-level evidence. It captures the dynamics of individual heterogeneous firms, describes the behavior of an industry with firm entry and exit, and delivers a general equilibrium model of technological change. While unifying the theoretical analysis of firms, industries, and the aggregate economy, the model yields insights into empirical work on innovating firms. It accounts for the persistence of firms' R&D investment, the concentrati...
