We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. We find a pseudo-Malthusian equilibrium in which population is constant and determined by resource scarcity while income grows exponentially. If...

We analyze the general-equilibrium effects of alternative regimes of access rights over renewable natural resources – namely, open access versus full property rights on the pace of development when economic growth is endogenously driven by both horizontal and vertical innovations. Resource...

This paper develops a theory of the emergence of modern innovation-driven Schumpeterian growth. It uses a tractable model that yields a closed-form solution, consisting of an S-shaped (i.e., logistic-like) time path of firm size and a set of equations that express the relevant endogenous...

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...

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...

I study the effects of product and labor market frictions in a dynamic general equilibrium model with a three-states representation of the labor market. Firms bargain with unions over wages and employment levels. This generates unemployment. Households take the associated unemployment risk as...

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...
