We analyze recent contributions to growth theory based on the model of expanding variety of Romer (1990). In the first part, we present different versions of the benchmark linear model with imperfect competition. These include the “labequipment” model, labor-for-intermediates” and...

Information and knowledge are essential to the decision making of firms. However, information is a primitive in the formation of knowledge. Information and the related concepts of risk and surprise are primarily of importance for rational decision making while knowledge is a form of...

We construct a competitive model of innovation and growth under constant returns to scale. Previous models of growth under constant returns cannot model technological innovation. Current models of endogenous innovation rely on the interplay between increasing returns and monopolistic markets. In...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

This paper examines the interaction between education, growth and distribution from a classical-Marxian perspective. It first briefly examines classical-Marxian ideas on the relation between education and growth and income distribution. Drawing on these ideas to the extent that they are relevant...

Neo-Schumpeterianism appeared in literature as a heterodox current and belongs to the evolutionary theories category. It works around and with innovation, considered to be a proper tool for measuring the qualitative changes which occur within an economy. The joint efforts of evolutionary...

In this paper we contend that – contrary to what argued by a vast part of the literature – computer software and, more in general, digital goods (i.e. symbolic strings on an electronic medium with some eco- nomic value) do not present the characteristics of a public good as they do not...

An evolutionary perspective on economic behavior has to account for the influences that the human genetic endowment has on the choices the agents make. Likely to have been fixed in times of fierce selection pressure, this endowment is presumably adapted to the living conditions of early humans....

Douglass North gehört zu den führenden Sozialwissenschaftlern des 20. Jahrhunderts. Er wurde für seine bahnbrechenden Leistungen auf dem Gebiet der ökonomischen Geschichtstheorie mit dem Nobelpreis ausgezeichnet. Dieser Aufsatz rekonstruiert (a) seine kliometrische Diagnose der Moderne, (b)...
