We modify an otherwise standard medium-sized DSGE model, in order to study the macroeconomic effects of placing leverage restrictions on financial intermediaries. The financial intermediaries ('bankers') in the model must exert effort in order to earn high returns for their creditors. An agency problem arises because banker effort is not observable to creditors. The consequence of this agency problem is that leverage restrictions on banks generate a very substantial welfare gain in steady state. We discuss the economics of this gain. As a way of testing the model, we explore its implications for the dynamic effects of shocks.

The US government has recently conducted large scale purchases of assets and implemented policies that reduced the cost of funds to financial institutions. Arguably these policies have helped to correct credit market dysfunctions, allowing interest rate spreads to shrink and output to begin a recovery. We study four models of financial frictions which explore different channels by which these effects might have occured. Recent events have sparked a renewed interest in leverage restrictions and the consequences of bailouts of the creditors of banks with under-performing assets. We use two of our models to consider the welfare and other effects of these policies.
