A number of plausible theories offer explanations for the propensity of many young industries to undergo a shakeout phase, during which the number of firms declines sharply in the face of continued rising output. However, none of the theories considers the role of labor market sorting. This...

The last fifty years have witnessed large secular increases in educational attainment and R&D intensity. The fact that these trends have not stimulated more rapid income growth has been a persistent puzzle for growth theorists. We construct a model of endogenous economic growth in which income...

Persistent trends in R&D intensity and educational attainment, in conjunction with the absence of any trend in per capita income growth, are inconsistent with the predictions of most growth models. Jones (2002) has made a strong point that the data are consistent with out-of-steady state...

This paper develops a neoclassical growth model with leisure externalities. Ignoring positive (negative) leisure externalities leads to equilibrium consumption, labor and capital that are too high (low) and leisure that is too low (high). The government should tax (subsidize) labor income...

This paper focuses on the role of government capital as a critical productive input when the level of services that the agent derives from it is subject to congestion. I develop a two-sector “nonscale” production model in which there are two types of firms, conventional profit-maximizing...

I develop a model with status concerns to analyze how different economic factors affect female participation, average household income and wage, as well as the welfare of both stay-at-home and working wives. Reductions in the price of domestic goods and increases in female wages have positive...
