In this paper I present an endogenous growth model where the engine of growth is in-house R&D performed by high-tech firms. I model knowledge (patent) licensing among high-tech firms. I show that if there is knowledge licensing, high-tech firms innovate more and economic growth is higher than in...

We revisit the issue of self-fulfilling "waves of enthusiasm" as stationary rational expectations equilibria in tournament models of horizontal and vertical R&D. By considering a lab-equipment specification, the model predicts a positive effect of animal spirits on the balanced-growth-path (BGP)...

This paper develops a tournament model of horizontal and vertical R&D under a lab-equipment specification. A key feature is that the overall growth rate is endogenous, as the splitting of the growth rate between the intensive and the extensive margin is itself endogenous. This setup gives rise...

The paper analyses the effect of the dynamics of consumption preferences on the dynamics of macroeconomic growth. We endogenously derive microdynamics of consumption behaviour as a result of the increase in the number of income classes. The different degrees of inertia in the adjustment of...

This paper constructs a growth model in which monopolistically competing firms choose the characteristic of their own product from an unbounded product space. While consumers wish to satisfy various needs by purchasing a diverse range of goods, production costs are lower for those goods that are...
