We study an economy where the lack of a simultaneous double coincidence of wants creates the need for a relatively safe asset (money). We show that, even in the absence of asymmetric information or an agency problem, the private provision of liquidity is inefficient. The reason is that liquidity...

The reason is that agents in...

We study the role of fiscal policy in a complete markets model where the only friction is the nonpledgeability of human capital.
