I discuss a model of endogenous innovation that brings to the forefront the in-house R&D activity of the modern corporation. In a symmetric oligopoly, firms undertake cost-reducing R&D subject to a research technology with incomplete spillovers. Concentration of sales and R&D resources determine...

I study the growth and welfare effects of integration in a world economy populated by global oligopolists. For economies that move from autarky to trade, I show that growth and welfare rise because exit of domestic firms is more than compensated by entry of foreign firms so that integration...

I explore the interaction of market structure and growth in a model of industrialization and endogenous technological change. Along the industrialization path, new manufacturing firms enter the market and expand the variety of goods available to consumers. Competing in the marketplace, firms...

Evidence shows that firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic firms...

What is the relationship between the rate of population growth and the rate of technological change? To answer this question, I discuss a model where increasing returns generate long-run growth but where the scale effect is absent. More precisely, the model predicts that steady-state...

We analyze the relative growth performance of open economies in a two-country model where different endowments of labor and a natural resource generate asymmetric trade. A resource-rich economy trades resource-based intermediates for final manufacturing goods produced by a resource-poor economy....

I propose a Schumpeterian analysis of the growth and welfare effects of a deficit-financed cut of the tax rate on distributed dividends. I find that income per capita growth initially accelerates and then decelerates, eventually converging to a long-run value lower than the starting one....

This paper takes a new look at the long-run implications of resource abundance. Using a Schumpeterian growth model that yields an analytical solution for the transition path, it derives conditions under which the curse of natural resources occurs and is in fact a curse, meaning that welfare...

This paper takes a new look at the long-run implications of resource abundance. It develops a Schumpeterian model of endogenous growth that incorporates an upstream resource-intensive sector and yields an analytical solution for the transition path. It then derives conditions under which, as the...

The growth literature on the Industrial Revolution has produced novel insights that have changed the way economists think about the issue. Most of the available models, however, focus on the household and do not put industrial activity at the center of the analysis. Consequently, they leave out...
