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 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...

Endogenous growth requires that non-reproducible factors of production be either augmented or eliminated. Attention heretofore has focused almost exclusively on augmentation. In contrast, we study factor elimination. Maximizing agents decide when to reduce the importance of non-reproducible...

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...

Evidence shows that firms build their market position by accumulating knowledge protected by secrecy, patents and other appropriation devices. I explore the implications of this fact in a model economy where oligopolistic firms establish in-house R&D programs. In symmetric equilibrium, the...

In the early stage of western industrialization, innovation was the domain of individuals who devoted their entrepreneurial talents to the development of a new product or process, typically setting up a new firm in order to take the innovation to the market. Today, commercial R&D is almost...

Unemployment occurs when some agents, say unions, have control over the wage and set it above the market-clearing level. In other words, it is generated by their exercise of market power. What if, in addition, firms have control over prices in the product market? In this case, market power of...

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...
