We evaluate the desirability of having an elastic currency generated by a lender of last resort that prints money and lends it to banks in distress. When banks cannot borrow, the economy has a unique equilibrium that is not Pareto optimal. The introduction of unlimited borrowing at a zero...

We examine optimal discount window policy in an economy with a linear investment technology and aggregate liquidity shocks. Unrestricted lending at the discount window prevents large shocks from causing banking crises, but leads to indeterminacy of stationary equilibrium. We show how a policy of...

We study the consequences of a central bank providing an elastic currency through the use of discount window lending. In particular, we compare the set of equilibria generated when the interest rate is fixed in nominal terms with that generated when it is fixed in real terms. The two policies...

We study the role of commitment in a version of the Diamond and Dybvig (JPE, 1983) model with no aggregate uncertainty. As is well known, the banking authority can eliminate the possibility of a bank run by committing to suspend payments to depositors if a run were to start. We show, however,...

We study the Green and Lin (2003) model of financial intermediation with two new features: traders may face a cost of contacting the intermediary, and consumption needs may be correlated across traders. We show that each feature is capable of generating an equilibrium in which some (but not all)...
