When will reducing trade barriers against a low wage country cause innovation to increase in high wage regions like the US or EU? We develop a model where factors of production have costs of adjustment and so are partially “trapped” in producing old goods. Trade liberalization with a low...

We test the hypothesis that information and communication technologies (ICT) “polarize” labor markets, by increasing demand for the highly educated at the expense of the middle educated, with little effect on low-educated workers. Using data on the US, Japan, and nine European countries from...

OECD labor markets have become more “polarized” with employment in the middle of the skill distribution falling relative to the top and (in recent years) also the bottom of the skill distribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partly due to...

This paper describes and explains some of the principal trends in the wage and skilldistribution in recent decades. There have been sharp increases in wage inequality across theOECD, beginning with the US and UK at the end of the 1970s. A good fraction of thisinequality growth is due to...

Business support policies designed to raise productivity and employment are common worldwide, but rigorous micro-econometric evaluation of their causal effects is rare. We exploit multiple changes in the area-specific eligibility criteria for a major program to support manufacturing jobs...

Adoption of health information and communication technologies ("HICT") has surged over the past two decades. We survey the medical and economic literature on HICT adoption and its impact on clinical outcomes, productivity and labor. We find that HICT improves clinical outcomes and lowers...

We examine the impact of Chinese import competition on patenting, IT, R&D and TFP using a panel of up to half a million firms over 1996-2007 across twelve European countries. We correct for endogeneity using the removal of product-specific quotas following China's entry into the World Trade...

Government policies to support R&D are predicated on empirical evidence of R&D "spillovers" between firms. But there are two countervailing R&D spillovers: positive effects from technology spillovers and negative effects from business stealing by product market rivals. We develop a general...

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A central problem in the literature is that firm performance is affected by two countervailing "spillovers" : a positive effect from technology (knowledge) spillovers and a...
