We derive the central differential equation of the neoclassical growth model for the case of a CES (constant elasticity of substitution) production function with perfect capital movement in terms of the debt/GDP ratio and estimate it in several ways for the United States and in a later step the...

We employ a general purpose technology model with endogenous stochastic growth to simulate the effects of different energy policy schemes. An R&D sector produces endogenous growth by developing radical and incremental technologies. These innovations result in blueprints for capital...

This case study provides insight into how a particular transformation of the innovation process affects individual companies and the regional Mechatronics system as a whole in the Eindhoven-Venlo region (The Netherlands). The transformation involves out-sourcing engineering activities by Océ,...

Neoclassical economists argue that competition promotes efficiency. They consider technology as given though. In the long run technological progress is an important determinant of the level of welfare and Schumpeter argued that monopoly rents help entrepreneurs to capture the gains of R&D and...

This paper models an economy in which a large number of agents are choosing among several technologies. There is a single, global, market for the technologies but they are subject to localized network externalities in use. We examine the issue of technological standardization, and the...

This paper explores the self-organising principles of horizontally-integrated innovation networks. It isshown that such networks can self-organising in environments where the co-ordination and production ofnew knowledge is itself a complex, dynamic and highly non-linear processes. The paper...

We examine a model of social learning in networks following the lines of Bala and Goyal (1998, 2001). As a model of agents’ behaviour we have chosen the model of informational cascades of Bikhchandani et al (1992). Similarly to Bala and Goyal we find that the higher the ’degree of...

We consider the problem between an employer and a research employee who has not finished a research project in time because of a lack of an innovative idea. The research project yields money in case of finishing it. The decision to be made is whether or not the researcher gets a contract...

This note shows that the antilog of Shannon’s entropy is a suitableindex of product variety for three reasons. First, for symmetricproduct types it is equal to the number of product types. Second, disaggregationof the underlying product set always leads to an increasein measured product...
