In the presence of utility penalties, collateral requirements do not always eliminate the occurrence of Ponzi schemes. Harsh utility penalties may induce effective payments over collateral recollection values. In this event, loans can be larger than collateral costs and Ponzi schemes become...

We develop a model of general equilibrium with trade ex ante in a context of private and incomplete state verification. Instead of choosing bundles, agents choose lists of bundles out of which the market then selects one bundle for delivery. With agents having subjective expectations about the...

This paper provides a new characterization of competitive equilibrium allocations based on the veto mechanism. The main theorem shows that, in pure exchange economies with a continuum of non-atomic agents, the competitive equilibria can be characterized by strengthening the veto power of the...
