The literature on 'horizontal innovation' claims to analyse the cases where unbounded endogenous growth comes from an increasing variety of intermediate goods. The present paper contends that a good sample of representative models in this literature share two essential assumptions regarding...

In this paper, we study how the privatization and deregulation of intermediate goods industries influence capital accumulation. Our model is solved under three alternative scenarios: (i) the intermediate sector is composed of a public monopoly under government control; (ii) the intermediate...

This paper deals with the role of bubbles, having the same meaning as Ponzi games, for implementing efficient growth paths in a closed economy overlapping generations model. It is shown that the well-known arbitrage condition for bubbles, namely that they must yield the same return in...

This paper proves the existence of competitive equilibrium in a single sector dynamic economy with heterogeneous agents and elastic labor supply. The method of proof relies on some recent results concerning the existence of Lagrange multipliers in inï¬nite dimensional spaces and their...

This paper reviews the cross-country record of economic growth, using as organizing framework how economic theory has guided that empirical analysis. The paper argues that recent studies of economic growth - both empirical and theoretical - distinguish from previous work in three distinct ways:...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We present a tractable model for analyzing the relationship between economic growth and the intensive and extensive margins of technology adoption. The "extensive" margin refers to the timing of a country's adoption of a new technology; the "intensive" margin refers to how many units are adopted...

The marginal product of human capital in Mankiw, Romer, and Weil´s [1992] augmented Solow model measures the direct and two external effects of human capital created from schooling on national income. If this model is valid, its estimates of the share of this marginal product accruing to...

This article presents revised estimates of the external rates of return on investment in schooling provided in Schooling and National Income: How Large Are the Externalities?" The analysis is based on data for the same set of countries, but it incorporates methodological improvements that yield...

This article presents revised estimates of the external rates of return on investment in schooling provided in “Schooling and National Income: How Large Are the Externalities?” The analysis is based on data for the same set of countries, but it incorporates methodological improvements that...
