A model of credit and government debt with limited commitment is constructed, building on a Lagos-Wright construct. In the baseline equilibrium, global punishments support an efficient equilibrium in which government debt is neutral - there is Ricardian equivalence. In a symmetric equilibrium...

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A...

We construct a model in which all consolidated government debt is used in transactions, with money being more widely acceptable. When asset market constraints bind, the model can deliver low real interest rates and positive rates of inflation at the zero lower bound. Optimal monetary policy in...

A model of money, credit, and banking is constructed in which the differential pledgeability of collateral and the scarcity of collateralizable wealth lead to a term premium — an upward-sloping nominal yield curve. Purchases of long-maturity government debt by the central bank are always a...
