In this paper, I analyze the time paths of the efficiencies of skilled and unskilled labor in aproduction framework where skilled and unskilled labor are imperfect substitutes. Theirimplications for economic growth and wage inequality in the US between 1950 and 2005present two main findings....

The paper revisits the debate on trickle-down growth in view of the widely discussed evolution of the earnings and income distribution that followed a massive expansion of higher education. We propose a dynamic general equilibrium model to dynamically evaluate whether economic growth triggered...

In a seminal paper Graetz and Michaels (2018) find that robots increase labor productivity and TFP, lower output prices and adversely aect the employment share of low-skilled labor. We show that these effects hold only, when comparing hardly-robotizing with highly-robotizing sectors and...

This paper presents a model of technical change that combines two lines of research together. It is a task based model, in which automation turns labor tasks to mechanized ones, and there is also a continuous addition of new labor tasks, as in the expanding variety literature. We impose three...

We analyze the effects of children's health on human capital accumulation and on long-run economic growth. For this purpose we design an R&D-based growth model in which the stock of human capital of the next generation is determined by parental education and health investments. We show that i)...

We show that skilled and unskilled labors are imperfect substitutes and that capital and skilled labor are complementary in production. The Korean economy has experienced skill-biased technical changes. The capital stock growth is found to be the main source of the economic growth. The...
