We propose an evolutionary equation and develop an asymptotic theory that generalize results obtained in Polterovich, Khenkin, 1988. It is shown that, as a result of interaction between innovation and imitation, the shape of the efficiency distribution curve of technologies eventually...

Competition between companies differentiates a lot nowadays compared to many years before. They compete in "nicety" that are so small but so important. Companies are trying to achieve competitive advantage in order to help them obtain a better and a stable position in the marketplace. The best...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent-policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary...

This paper contributes to the literature on institutions and economic growth by conducting an empirical examination on the links between innovation and institutions. Using cross-country data and the instrumental variable method, this study finds that institutional arrangements explain much of...

The main objective of this paper is to evaluate technologically (innovation or imitation) the role of human capital in Cameroon as far as economic growth is concerned. Higher education is designed to be the main technological aspect of human capital. Theoretically, the stock of knowledge...

Since Arrow (1962), spillovers from pioneer to follower in non-excludable innovations are central to our understanding of endogenous economic growth. Nonetheless, evidence of these spillovers in less-developed economies has been elusive. Our paper contributes by showing novel facts consistent...

This study develops a Schumpeterian growth model to analyze the effects of different patent instruments on innovation. We first analyze patent breadth that captures the traditional positive effect of patent rights on innovation. Then, we consider a profit-division rule between entrants and...

The article discusses a critical realist interpretation of evolutionary growth theorising by focusing on some of its basic characteristics. The evolutionary ontology is complex, differentiated, structured, systemic, open, ever-changing, and radically uncertain. Its methodology tends to be...

This study develops an R&D-based growth model with basic and applied research to analyze the growth and welfare effects of two patent instruments (a) the patentability of basic R&D and (b) the division of profi�t between basic and applied researchers. We �find that for the purpose of...

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent...
