In this paper, we use a multi-sector specific factors model with international capital mobility to examine the effects of globalization on the skill premium in U.S. manufacturing industries. This model allows us to identify two channels through which globalization affects relative wages: effects of international capital flows transmitted through changes in interest rates, and effects of international...

This paper analyzes the dynamic interactions between the precision of information, technological development, and welfare within an overlapping generations model. More precise information about idiosyncratic production shocks has ambiguous effects on technological progress and welfare, which depend critically on the risk sharing capacity of the economy’s financial system. For example, we show t...

I use U.S. manufacturing industry data to estimate a system of three equations implied by a model of R&D-induced growth in steady state. These three equations relate R&D intensity to patenting, patenting to technological progress, and technological progress to economic growth. In each case, I find evidence of positive impact. Thus, I reject the null hypothesis that growth is not induced by R&D ...
