Enriching information to prevent bank runs

Abstract

Sequential service in the banking sector, as modeled by Diamond and Dybvig (1983), is a barrier to full insurance and potential source of financial fragility against which deposit insurance is infeasible (Wallace, 1988). In this paper, we pursue a different perspective, viewing the sequence of contacts as opportunities to extract information through a larger message space with commitment to richer promises. As we show, if preferences satisfy a separating property then the desired elimination of dominated strategies (Green and Lin, 2003) occurs even when shocks are correlated. In this manner the sequential service promotes stability.
