Semi-endogenous models and, to some extent, also Schumpeterian models are based on the assumption of diminishing returns to R&D. This paper shows that the null hypothesis of constant returns to R&D cannot be rejected for the OECD countries.

The approach put forward in this article is based on Schumpeter`s idea of creative destruction, the competitive process by which entrepreneurs are always looking for new ideas that will render their rivals` ideas obsolete. I present a model in which the rate of economic growth is sensitive to...

This paper studies an agent-based model that bridges Keynesian theories of demandgeneration and Schumpeterian theories of technology-fueled economic growth. We employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply, demand and the...

We consider an R&D-driven endogenous growth model in which innovation is risky and agents are risk averse. Growth is determined by the occupational choice of agents who can either work in production for a wage or become entrepreneurs. In this context, we examine the impact of redistributive...

This paper presents an overview of the literature on 'cumulative growth'. It is argued that, independently of the 'new' growth theory, these models have achieved the nature of 'endogenous' growth models. Their main differences, however, lie in the assumptions about the equilibrium prevailing in...

In an influential paper Mankiw, Romer, and Weil (1992) argue that the evidence on the international disparity in per-capita income levels and growth rates is consistent with a standard Solow model, once it has been augmented to include human capital as an accumulable factor. In a study on...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups. Trade induces only firms with high-quality products to export, whereas firms with low-quality products serve only the...
