The prize system for innovation has been criticized as impractical due to the lack of a workable formula or algorithm to determine the size of prizes. In this paper, a decentralized market mechanism via the intertemporal bounty (IB) system can function to duplicate Pareto optimality. Under this...

This paper presents a Finite Element Model, which has been used for forecasting the diffusion of innovations in time and space. Unlike conventional models used in diffusion literature, the model considers spatial heterogeneity. The implementation steps of the model are explained by applying it...

The statutory patent length is 20 years in most countries. R&D-based endogenous growth models, however, often presume an infinite patent length. In this paper, finite-length patents are embedded in a non-scale R&D-based growth model, but any patent’s effective life may be terminated...

It is a central tenet in the literature on organizational change that firms need to explore novel courses of action in order to adapt and survive. Should firms thus exhibit a “pro-innovation bias” when evaluating novel decision alternatives? Or should firms rather assess new opportunities as...

This paper analyses an entry timing game with uncertain entry costs. Two firms receive costless signals about the cost of a new project and decide when to invest. We characterize the equilibrium of the investment timing game with private and public signals. We show that competition leads the two...

Schumpeter’s idea that innovations can be described as new combinations often is understood as a mere metaphor and slight generalization of what he considers as the characterizing feature of entrepreneurship. The main argument of this paper is that more and deeper issues are involved in the...

Innovations, be they radical new products or technology improvements are widely recognized as a key factor of economic growth. To identify the factors triggering innovative activities is a main concern for economic theory and empirical analysis. As the number of hypotheses is large, the process...

Cooperation can benefit and hurt firms at the same time. An important question then is: when is it better to cooperate. And how can an appropriate partner be selected? In this paper we present a model of inter-firm cooperation driven by cognitive distance, appropriability conditions and external...

We study theoretically and numerically the effects of an environmental tax reform using endogenous growth theory. In the theoretical part, mobile labor between manufacturing and R&D activities, and elasticity of substitution between labor and energy in manufacturing lower than unity allow for a...
