The canonical supply-demand model of the wage returns to skill has been extremely influential; however, it has faced several important challenges. Several studies show that the standard approach sometimes produces theoretically wrong-signed elasticities of substitution, yields counterintuitive...

This paper studies how linear tax and education policy should optimally respond to skill-biased technical change (SBTC). SBTC affects optimal taxes and subsidies by changing i) direct distributional benefits, ii) indirect redistributional effects due to wage-(de)compression, and iii) education...

The large cities in the US are the most expensive places to live. Paradoxically, this cost is disproportionately paid by workers who could work remotely, and live anywhere. The greater potential for remote work in large cities is mostly accounted for by their specialization in skill- and...

Since 1980, economic growth in the U.S. has been fastest in its largest cities. We show that a group of skill- and information-intensive service industries are responsible for all of this new urban bias in recent growth. We then propose a simple explanation centered around the interaction of...

We study the economic effects of information technology (IT) adoption during the COVID-19 pandemic. Using data on IT adoption covering almost three million establishments in the US, we find that technology adoption can partly shield the economy from the impact of the pandemic. In areas where...

With the ensuing immigration reform in the US, the paper shows that targeted skilled immigration into the R&D sector that helps low-skilled labor is conducive for controlling inequality and raising wage. Skilled talent-led innovation could have spillover benefits for the unskilled sector while...

This paper investigates whether and to what extent long-run trends in population health affected income inequality in the United States over the period 1960-2000. To isolate exogenous variation in health over time, the analysis exploits the sharp decline in cardiovascular disease mortality...

How important is mastering information and communication technologies (ICT) in modern labor markets? We present the first evidence on this question, drawing on unique data that provide internationally comparable information on ICT skills in 19 countries. Our identification strategy relies on the...

In this article we estimate the long-run aggregate elasticity of substitution between skilled and unskilled workers. This is an important parameter as it allows us to compute the skill biased technological progress (SBTP) from the evolution of relative wages. However, it is hard to estimate...
