Although open source software has recently attracted a relevant body of economic literature, a formal treatment of the process of com- petition with its proprietary counterpart is still missing. Starting from an epidemic model of innovation di?usion, we try to ?ll this gap. We propose a model...

This paper explores competitive positioning through network competition on the basis of alliance formation (strategic alliances, joint ventures). From a strategic perspective, technological competition will be refined and expanded into new markets, or new markets will be created through alliance...

The article presents a stochastic interaction model based on Gibbs random fields to analyze technological competition in a population of heterogeneous adopters with local or global externalities. The relationships between both heterogeneity and externalities and imperfect and asymmetric...

We evaluate the social welfare loss (WL) that arises in an oligopolistic industry under technological competition and product differentiation. The main novelty of our approach concerns the decomposition of the WL into `dynamic' losses (from too little cost reduction and an inappropriate number...

The world’s people and their leaders face a complex and multifaceted set of ‘eco-social questions’. As the productivity of humanity increases, the negative external environmental effects of production and consumption patterns become increasingly problematic and threaten the human welfare....

This paper focuses on the diversity of engine technologies for Low Emission Vehicles (LEVs) that are developed by car manufacturers in order to substitute for the conventional internal combustion engine vehicle. Our purpose is to analyse the competition between the various technologies for LEVs...

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity....

Data on broadband performance shows that Japan and Korea are significantly ahead of the USA and Europe. Korea is by far the global front-runner in terms of broadband penetration. However, Japan is the global leader in terms of speed, price and diffusion of advanced technology (specifically...

China, Indien und Korea sind aufgrund ihrer Wachstumsdynamik, aber vor allem auch als Konkurrenten und Kooperationspartner auf den Technologiemärkten in den weltweiten Fokus gerückt. Auslösendes Moment für den technologischen Aufholprozess war die Öffnung für ausländische Unternehmen und...
