Although the college-high school wage gap for younger men has doubled over the past 30 years, the gap for older men has remained nearly constant. We argue that these shifts reflect changes in the relative supply of highly-educated workers across age groups. Cohorts born in the first half of the...

In recent papers, Nelson and Pack (1995) , Rodrik (1997), and Hsieh (1997a) argue that standard measures of total factor productivity growth in countries where the capital-labour ratio has risen rapidly, e.g. the East Asian NICS, will understate true productivity growth if the elasticity of...

We estimate three first order conditions which …, present leisure for future leisure and present consumption for present leisure. Our results show that the aggregate U.S. data … imply that either consumption or leisure is an inferior good …

In this paper, necessary and sufficient conditions for an asset substitution matrix to be symmetric for all distributions of rates of return are derived. It is found that symmetry in this context is essentially equivalent to the proposition that the von Neumann-Morgenstern utility function...

In this paper, I study asset prices in a two-agent macroeconomic model with two key features: limited participation in the stock market and heterogeneity in the elasticity of intertemporal substitution in consumption (EIS). The model is consistent with some prominent features of asset prices...

Consistent with two models of imperfect competition in the labor market, the efficient bargaining model and the monopsony model, we provide two extensions of a microeconomic version of Hall's framework for estimating price-cost margins. We show that both product and labor market imperfections...

This paper develops a graphical analysis and an analytical model that demonstrate how weak substitution can be used for non-market valuation. Both weak complementarity and weak substitution can be evaluated as restrictions that allow quantity or quality changes in non-market goods to be...

We document a change in household shopping behavior during the Great Recession. Households purchased more on sale, larger sizes and generic products, increased coupon usage, and shopping at discount stores. We estimate that the returns to these shopping activities declined during the recession...
