In this paper we study the behavior of optimal paths in dynamic programming models with a strictly convex return function. Such a model has been investigated in Dawid and Kopel (1997) who assume that the growth of a renewable resource is governed by a piecewise linear function. We prove that in...

This paper analyzes how the transferability of production capacities from an established to a new product influences the incentives of a firm to invest in R&D. A dynamic duopoly model is considered, where initially both firms offer a homogeneous product. The firms invest in production capacities...

We employ a dynamic market model with endogenous creation of submarkets to study the optimal product innovation strategies of incumbent firms. Firms invest in production capacity and R&D knowledge stock, where the latter determines the hazard rate of innovation. We find that under Markov Perfect...

We study in a dynamic framework how product innovation activities of a firm are influenced by its production capacity investments for an established product and vice versa. The firm initially has capacity to sell an established product, and it also has the option to undertake an R&D project,...

This paper explores the idea of using artificial adaptive agents in economic theory. In particular, we use Genetic Algorithms (GAs) to model the learning behavior of a population of adaptive and boundedly rational agents interacting in an economic system. We analyze the behavior of a GA in two...

In this paper a quantity-setting duopoly is considered where one firm develops a new product which is horizontally differentiated from the existing product. The main question examined is which strategically important effects occur if the decision to develop the innovation and the decision to...

This paper considers investment behavior of duopolistic firms subject to technological progress. It is assumed that initially both firms offer a homogeneous product, but after a stochastic waiting time they are able to implement a product innovation. Production capacities of both firms are...

We consider a repeated interaction between a manufacturing firm and a subcontractor. The realtionship between the two parties is characterized 1) by moral hazard, 2) by the fact that they do not have perfect knowledge about the base cost level of the project carried out by a subcontractor (the...

This paper considers investment behavior of duopolistic firms subject to technological progress. It is assumed that initially both firms offer a homogeneous product, but after a stochastic waiting time they are able to realize a product innovation. Production capacities of both firms are product...

The paper addresses the question how production capacities on an established market affect the innovativeness of firms. We analyze the strategic interactions in an oligopoly setting where firms offer an established product and have the option to offer an additional new product. We show that the...
