Communication Mechanisms in Competition

I examine how a market mediator can help to disseminate financial information among asymmetrically informed market players using only a communication channel. I introduce a mediator whose function is a collection of financial information from the players and sharing of this information with the market. The crucial assumption is that information disclosure to the mediator by the market players is voluntary. Given that the mediator can commit to a reporting policy, the paper studies the information reporting policy that the mediator should adopt in order to minimise the probability of inefficient investments by less informed market players. I show that a manipulation of the first order beliefs of less informed players is not sufficient to extract private information from more informed players. The main insight of the paper shows that allowing more informed players who share information to know the degree to which this information was shared with the market incentivises information disclosure.

Strategic default, Investments and Resolution of Financial Distress (joint with Giulio Trigilia)

In recent years, the U.S. experienced an increase in the share of default events that are resolved out-of-court, as well as a reduction in bankruptcy-related costs.This trend raises the question as to what drives the frequency with which defaults turn into bankruptcies. We propose a theory based on three pillars: first, bankruptcy is costlier than out-of-court restructuring; second, creditors cannot commit to take defaulting borrowers to court; third, firms have private information about the value of their assets, outside investors learn them only upon bankruptcy. Creditor’s bargaining power upon default decreases with bankruptcy costs and it increases with the frequency of strategic default – that is, default by firms which could have honored their obligations. When bankruptcy costs decrease, creditors obtain higher recovery rates out-of-court and therefore firms have lower incentives to default strategically. As a result, bankruptcy can occur less frequently.
