Is the reputation of a firm tradable when the change in ownership is observable? We consider a competitive market in which a share of owners must retire in each period. New owners bid for the firms that are for sale. Customers learn the owner's type, which reflects the quality of the good or...

For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment. We study this incentive for investment in OSS. In...

In this paper, I compare two different approaches to model implicit contracting, the infinite-horizon approach typically used in the literature and afinite-horizon approach building on an adverse-selection model. I demonstrate that even the most convincing result of the infinite-horizon...

Financial markets and macroeconomic environments are often characterized by positive externalities. In these environments, transparency may reduce expected welfare from an ex-ante point of view: public announcements serve as a focal point for higher-order beliefs and affect agents' behaviour...

This paper uses a new data set on budgetary institutions in Europe to examine the impact of fiscal rules and budget procedures in EU countries on public finances. It briefly describes the main pattern of budgetary institutions and their determinants across the EU 15 member states. Empirical...

Consider a two-product firm that decides on the quality of each product. Product quality is unknown to consumers. If the firm sells both products under the same brand name, consumers adjust their beliefs about quality subject to the performance of both products. We show that if the probability...

Where product innovation requires several complementary patents, fragmented property rights can be a factor that limits firms' willingness to invest in the development and commercialization of new products. This paper studies multiple simultaneous R&D contests for complementary patents and how...

Fiscal rules specify quantitative targets for key budgetary aggregates. In this paper, we review the experience with such rules in Japan and in the EU. Comparing the performance of fiscal policy in the 1980s and 1990s until 2003, we find that the fiscal rule of the 1980s exerted some but not...

We consider a Rothschild-Stiglitz-Spence labour market screening model and employ a centralised mechanism to coordinate the efficient matching of workers to firms. This mechanism can be thought of as operated by a recruitment agency, an employment office or head hunter. In a centralised...

In this paper, a principal's decision between delegating two tasks or handling one of the two tasks herself is analyzed. We assume that the principal uses both, formal contracts and informal agreements sustained by the value of future relationships (relational contracts) as incentive device. It...
