Drawing on a large database of publicly announced R&D alliances, we track the evolutionof R&D networks in a large number of economic sectors over a long time period (1986-2009). Our main goal is to evaluate temporal and sectoral robustness of the main statisticalproperties of empirical R&D...

This work introduces a new model to investigate the efficiency and evolution of networks of firms exchanging knowledge in R&D partnerships. We first examine the efficiency of a given network structure in terms of the maximization of total profits in the industry. We show that the efficient...

This work introduces a new model to investigate the efficiency and evolution of networks of firms exchanging knowledge in R&D partnerships. We first examine the efficiency of a given network structure from the point of view of maximizing total profits in the industry. We show that the efficient...

Face au ralentissement des ventes de véhicules, le « Pacte automobile » mobilise 9 milliards d’euros pour venir en aide aux constructeurs français. L’enjeu est triple : soutenir à court terme la demande et l’emploi, assurer l’avenir d’une industrie stratégique au regard des...

This paper investigates economic performance and policies in OECD countries. Our hypothesis is that the effects of policy are determined by country-size. We employ non parametric distribution dynamics techniques (e.g. Quah, 1993) and we analyze differences across and within groups of countries...

Using the “Keynes+Schumpeter” (K+S) agent-based model developed we study how the interplay between firms’ investment behavior and income distribution shapes the short—and long-run dynamics of the economy at the aggregate level. We study the dynamics of investment under two different...

Many of the factors responsible for the financial crisis (financial innovation ans securitization ;heterogeneity of agents, markets and regulatory framworks) are by and large overlooked by standard macroeconomic models which have failed to forecast the advent of the crisis and are unable to...

This work explores some distributional properties of aggregate output growth-rate time series. We show that, in the majority of OECD countries, output growth-rate distributions are well-approximated by symmetric exponential-power densities with tails much fatter than those of a Gaussian. Fat...

This work studies the interactions between income distribution and monetary and fiscal policies in terms of ensuing dynamics of macro variables (GDP growth, unemployment etc.) on the grounds of an agent-based Keynesian model. The direct ancestor of this work is the "Keynes meeting Schumpeter"...
