Diversity of Innovative Strategy as a Source of Technological Performance

This paper explores the impact of diversity of innovative strategies of firms upon the industrial dynamics through a micro-simulation model. We consider two types of firms each one being characterised by a specific innovative strategy. Basically we assume that some cumulative firms adopt an internal learning by searching strategy, while noncumulative firms adopt an external learning strategy aiming at absorbing external sources of knowledge. The results show that the co-existence of the two types of firms leads to an oligopolistic structure characterised by asymmetries in the size of firms and high technological performances. Thus the diversity of innovative strategies generates a diversity in firms market shares and is a source of dynamic efficiency in the long run.Industrial dynamics, innovation, diversity, learning

Alternative Theories on Economic Growth and the Co-evolution of Macro-Dynamics and Technological Change: A survey.

This paper aims to propose an approach to endogeneous growth considering the relationship between macro-dynamics and technical change. We draw upon two stream of literature: Cumulative causation and its macroscopic view of economic dynamics, and Evo-lutionary economics and its focus on micro-determinants of technical change. This paper presents a survey of the formal representation of the growth process and identifies the possible bridges between these two approaches. Our claim is that merging these two distinct theories might offer a framework to consider the co-evolution of macro-dynamics and technical change.Economic Growth, Technical Change, Cumulative Causation, Evolutionary Theory.

Socio-technical transition processes: A real option based reasoning.

Using a real option reasoning perspective we study the uncertainties and irreversibilities that impact the investment decisions of firms during the different phases of technological transitions. The analysis of transition dynamics via real options reasoning allows the provision of an alternative and more qualified explanation of investment decisions according to the sequentiality of pathways considered. In our framework, flexibility management through option investments concerns both the incumbent and the future technological regime. In the first case it refers to ex-post flexibility management and in the second case to ex-ante flexibility management.

Von Neumann-Morgenstern solution and convex descompositions of TU games

We study under which conditions the core of a game involved in a convex decomposition of another game turns out to be a stable set of the decomposed game. Some applications and numerical examples, including the remarkable Lucas five player game with a unique stable set different from the core, are reckoning and analyzed.convex games, cooperative games, stable sets

Eliciting values for environmental attributes of a private good using a real choice experiment

Markets for environmentally friendly products have been expanding during the last decade. These products provide both private benefits to the consumer and environmental – public – benefits. The demand for environmentally friendly products has consequently received a growing interest. Our study aims at studying consumers' choices for a non-food product, i.e. roses, with different environmental attributes. We combine a choice experiment with a laboratory experiment to provide real economic incentives.Choice experiment, environmental attributes, real economic incentives, Environmental Economics and Policy,

A geometric characterization of the nucleolus of the assignment game

Maschler et al. (1979) provide a geometrical characterization for the intersection of the kernel and the core of a coalitional game, showing that those allocations that lie in both sets are always the midpoint of certain bargaining range between each pair of players. In the case of the assignment game, this means that the kernel can be determined as those core allocations where the maximum amount, that can be transferred without getting outside the core, from one agent to his/her optimally matched partner equals the maximum amount that he/she can receive from this partner, also remaining inside the core (Rochford, 1984). We now prove that the nucleolus of the assignment game can be characterized by requiring this bisection property be satisfied not only for optimally matched pairs but also for optimally matched coalitions.assignment game, core, kernel, nucleolus

Cumulative Causation and Evolutionary Micro-Founded Technical Change: A Growth Model with Integrated Economies

We propose to develop in this paper an alternative approach to the New Growth Theory to analyse growth rate divergence among integrated economies. The model presented here considers economic growth as a disequilibrium process. It introduces in a cumulative causation framework, micro-founded process of technical change taking into account elements rooted in evolutionary and Neo-Austrian literature. We then attempt to open the "Kaldor-Verdoorn law black-box" using a micro-level modelling of industrial dynamics. We use this framework to study the nature and sources of growth rate divergence, focusing on the eect of some macro-economic parameters (income elasticities) and of some technological parameters (technological opportunities and absorptive capacities). If the results remain broadly in Kaldorian lines, this framework allows for more subtle considerations of growth rate divergence.Cumulative Growth, Technical Change, International Trade
