In 1960 Theodore Schultz expounded a human capital theory of economic growth that includes three elements: 1) Countries without much human capital cannot manage physical capital effectively, 2) Economic growth can only proceed if physical capital and human capital rise together, and 3) Human...

The two notes deal (from different angles) with the extension of the Solow model that has been offered by Mankiw, Romer and Weil (MRW). In this `extended Solow' model, physical capital enters the production function with the same weight as human capital and both weights are about 1/3. The first...

The usual models of endogenous growth treat knowledge codification as a byproduct of R&D and as costless. In contrast to this, one can observe great efforts of private firms for the purposeful codification of knowledge. We incorporate costly knowledge codification in an overlapping generations...

This paper presents and estimates a unified model where both human capital investment and job search are endogenized. This unification enables us to quantify the relative contributions of each mechanism to life cycle earnings growth, while investigating potential interactions between human...
