We consider a model of factor saving innovations and study the effects of exogenous changes in labor supply. In a biased innovations setting, as economies accumulate capital, labor becomes relatively scarce and expensive. As a consequence, incentives for labor saving and capital using...

This paper explores the evolution of child labor, fertility, and human capital in the process of development. In early stages of development the economy is in a development trap where child labor is abundant, fertility is high and output per capita is low. Technological progress, however,...

The traditional explanation of growth based on the primum and secundum movens of accumulation and technical progress, faces two major empirical anomalies. Why do people work so much i.e. why do they strive so much for money? The growth literature provides no answer to these question, nor to the...

An informal model is described that leads to multiple macroeconomic equilibria as a consequence of random variation in the relative amounts of technological change for new and existing goods. The novel observation is that the rate of introduction and market penetration of new goods vis-a-vis...

In this paper we investigate the long-run growth process in Italy and the US over the period 1920-2001, using a common trends model. Coherent with the neoclassical growth model, we find that long-run economic growth can be explained by two permanent shocks, namely a technological shock and a...

This paper contributes to a large literature concerned with identifying the source of the widening wage gap between high school and college graduates by providing a comprehensive, multidimensional decomposition of wages across both time and educational status. Data from a multitude of sources...
