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...

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...

Les stratégies de croissance visent généralement à améliorer les conditions d’offre lesquelles sont censées déterminer le taux de croissance potentiel. La demande est reléguée au rang de variable qui n’influence le produit et l’emploi qu’à court terme. La condition sine qua non...

Are current economic models well equipped to provide useful policy prescriptions? Many economists would have certainly answered, “yes” before the recent Global Recession. This economic crisis has not only demonstrated the importance of banking and financial markets for the dynamics of real...

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...

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...

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 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...
