This paper analyzes the production of fundamental research as a coordination game played by scholars. In the model, scholars decide to adopt a new idea only if they believe that a critical mass of peers is following a similar research strategy. If researchers observe only a noisy idiosyncratic...

In the model, a group of investors are invited to participate to a high-yield collective project. The project succeeds only if a minimum participation rate is reached. Before taking their decision, investors receive a vague statement about the outcome of a past investment decision. If investors...

In April 2013, all of the major academic publishing houses moved thousands of journal titles to an original hybrid model, under which authors of accepted papers can choose between an expensive open access track and the traditional track available only to subscribers. This paper argues that...

This paper argues that in Euro-area economies, where the ECB cannot bail-out …nancially distressed governments, the …scal multiplier is adversely a¤ected by the amount of public debt. A regression model on a panel of 26 EU countries over the period 1996-2011 shows that a 10 percentage point...

If a dollar denominated external debt comes with so many risks, why do emerging economies allow for such an imbalance to accumulate ? The explanation provided in this paper builds on a simple signaling model. By assumption, lenders have no direct possibility to infer a firm’s financial stance....

This paper analyzes the decision of a migrant to return or stay within the framework of a signaling model with exogenous migratory costs. If employers have only imperfect information about the type of a worker and good workers migrate, bad workers might copy their strategy in order to get the...

Criticism is mounting on business schools for their excessive focus on research and for neglecting teaching. We show that if students have imperfect information about a school’s overall capabilities and if business schools differ in their research productivity, the least productive schools may...

As a reaction to the corporate scandals of the early 2000s, the US Administration dramatically tightened sanctions against managers who disclose misleading financial information. This paper argues that such a reform might come with some unpleasant macroeconomic effects. The model is cast as a...

This short paper analyzes banks' communication policies in crisis times and the role of imperfect information in enhancing banks' distress. If banks differ in their exposure to risky assets, fragile banks may claim to be solid only in order to manipulate investors' expectations. Then solid banks...

Continental European countries used to finance defence firms with public money. In the last few years, many governments aimed at implementing a hands-off policy towards the defence sector, which implies a gradual transition from public to private funding. This paper argues that the absence of...
