Ses travaux de recherche proposent une analyse des dynamiques économiques comme des processus évolutionnistes. Ses travaux s’intéressent aussi bien aux mécanismes longs des dynamiques macroéconomiques, de transformations structurelles de l’emploi ou de la demande, à une économie politique évolutionniste de la crise de l’Euro qu’aux motivations évolutionnistes des décisions économiques individuelles aux travers de l’apprentissage du consommateur, d’une approche du progrès par le bien-être ou l’adaptation individuel dans l’organisation de la firme.

His research analyses economic dynamics as evolutionary processes at multiple level of analysis. On the one hand, his research works tackle both long and short-run macroeconomic dynamics, such as the structural transformation of employment and that of demand, as well as an evolutionary perspective on the political economy of the Euro-crisis. On the other hands he has been working on the motivational underpinnings of individual economic behaviors through the development of an adaptive and learning theory of consumption, an evolutionary theory of welfare and progress as well as the role of individual adaptation in firms organisation.

"Sometimes innovations turn out to cause severe negative externalities only after they have successfully passed the market test, i.e. are widely adopted and used. In the worst case, the ex post revealed social costs may even result in welfare losses. The present paper therefore discusses whether it is possible to design measures that prevent, or at least substantially reduce, the likelihood of such undesirable outcomes of the innovation process. More specifically, it is explored whether knowledge flows related to innovation processes can be strategically arranged in such a way that externality risks are excluded or kept low. The options to be reviewed relate to the debate on open vs. closed innovation processes initiated in management science. The paper briefly recapitulates several aspects of this debate and introduces a model of self-organizing belief formation which reflects the conditions of open vs. closed innovation processes. On this basis it is shown that a conflict arises between arrangements fostering an early discovery of negative externalities of innovations and the incentives potential innovators have to pursue innovative activities."
