The transitional dynamics for both a developed and a less developed country are derived when North-South trade leads to technological diffusion through reverse engineering of intermediate goods in a quality ladder model of endogenous growth. Domestic technological progress occurs via innovation...

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...

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...
