This paper studies how comparing can be used to provide information in financial markets in the presence of a hidden characteristics problem. Although an investor cannot precisely estimate the future returns of an entrepreneur’s projects, the investor can mitigate the asymmetric information...

Transparency regulation aims at reducing financial fragility by strengthening market discipline. There are however two elementary properties of banking that may render such regulation inefficient at best and detrimental at worst. First, an extensive financial safety net may eliminate the...

The banking system is known to be vulnerable to self-fulfilling crises that are caused by depositors’ coordination failure. We show that transparency regulation may prevent certain types of systemic crises by eliminating the possibility of the coordination failure.

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...

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 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...
