The foundations of incomplete contracts have been questioned using or extending the subgame perfect implementation approach of Moore and Repullo (1988). We consider the robustness of subgame perfect implementation to the introduction of small amounts of asymmetric information. We show that...

This paper studies whether agents must agglomerate at a single location in a class of models of two-sided interaction. In these models there is an increasing returns effect that favors agglomeration, but also a crowding or market-impact effect that makes agents prefer to be in a market with...

The recent unravelling of the Eurozone's financial integration raised concerns about feedback loops between sovereign and banking insolvency. This paper provides a theory of the feedback loop that allows for both domestic bailouts of the banking system and sovereign debt forgiveness by...

A major policy issue in standard setting is that patents that are ex-ante not that important may, by being included into the standard, become standard-essential patents (SEPs). In an attempt to curb the monopoly power that they create, most standard-setting organizations require the owners of...

This paper analyzes the impact of labor market competition and skill-biased technical change on the structure of compensation. The model combines multitasking and screening, embedded into a Hotelling-like framework. Competition for the most talented workers leads to an escalating reliance on...

Incorporating agents' imperfect knowledge of the distribution of preferences opens up to analysis several new questions. The first is social psychologists' practice of "norms-based interventions", namely campaigns and messages that seek to alter people's perceptions of what constitutes "normal"...

This paper analyzes the possibility and the consequences of rational bubbles in a dy- namic economy where financially constrained firms demand and supply liquidity. Bub- bles are more likely to emerge, the scarcer the supply of outside liquidity and the more limited the pledgeability of...

The paper elicits a mechanism by which private leverage choices exhibit strategic complementarities through the reaction of monetary policy. When everyone engages in maturity transformation, authorities have little choice but facilitating refinancing. In turn, refusing to adopt a risky balance...

The sub-prime crisis has shown a harsh spotlight on the practices of securities underwriters, which provided too many complex securities that proved to ultimately have little value. This uproar calls attention to the fact that the literature on intermediaries has carefully analyzed their...

We explore the link between liquidity and investment in a an overlapping generation model with a standard asynchronicity between firms' access to and need for cash. Imperfect pledgeability hinders the capacity of capital markets to resolve this asynchronicity, resulting in credit rationing and a...
