This paper studies the welfare effects of R&D subsidies. We develop a model of continuous optimal treatment with outcome heterogeneity where the treatment outcome depends on applicant investment. The model takes into account heterogeneous application costs and identifies the treatment effect on...

We study the interaction between private and public funding of innovative projects in the presence of adverse-selection based financing constraints. Government programmes allocating direct subsidies are based on ex-ante screening of the subsidy applications. This selection scheme may yield...

We study whether and to what extent financial exchange innovations are in practice patentable in Europe. We find that exchange-related applications initially increased significantly after the State Street decision but subsequently decreased. The clear majority (65%) of applications come from the...

Consider a competitive bank whose illiquid asset portfolio is funded by short-term debt that needs to be refinanced before the asset matures. In this setting, we show that maximal transparency is not socially optimal, and that the existence of social externalities of bank failures reduces...

We build a simple model to study service fee competition between an incumbent and an independent ATM deployer, and its optimal regulation. We use the model to analyze an actual regulation of such a market by competition authorities in Finland. We find that socially optimal first-best fees would...

Economic interest in innovation policy largely arises from the fundamental importance of innovation to social welfare and from inefficiencies in innovation in a competitive market environment. As a result, a wide variety of public innovation policies are used in practice. This study reviews the...

We extend the theoretical basis of the empirical literature on the effects of R&D subsidies by providing an estimable model of strategic interaction among subsidy applicants, and public and private sector R&D financiers. Our model incorporates fixed R&D costs and a cost of external finance. We...

In this article we first document the evidence showing how an efficient retail payment infrastructure enhances economic performance. We then review the policy tools available to promote efficient retail payments in Europe. We argue that while SEPA is an important policy initiative that...

We establish that the effect of intensified deposit market competition, measured by reduced switching costs, on the probability of bank failures depends critically on whether we focus on competition with established customer relationships or competition for the formation of such relationships....

​We build a dynamic stochastic general equilibrium model, where the balance sheets of both banks and non-financial firms play a role in macro-financial linkages. We show that in equilibrium bank capital tends to be scarce, compared with firm capital. We study public funding of banks and firms...
