We study economies where government currency and electronic money, drawn from interest bearing deposits in private financial intermediary institutions, are full substitutes. We analyze the impact of competition on policy outcomes under different assumptions regarding: the objectives of the...

The optimal inflation tax is computed in monetary models where money is costly to supply. The models are simple general equilibrium models with money in the utility function or a transactions technology. The inflation tax is a means of raising taxes to finance exogenous government expenditures....

We study a dynamic equilibrium model where the same optimal monetary policy is implemented with and without full commitment if government debt is indexed. In contrast, with nominal debt, the full commitment policy is time inconsistent, since the government is tempted to inflate away its nominal...

We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

We study a model where households make decisions according to a dual-process framework widely used in cognitive psychology. System 1 uses effortless heuristics but is susceptible to biases and errors. System 2 uses mental effort to make more accurate decisions. Through their pricing behavior,...

We study the interplay between competition and trust as efficiency-enhancing mechanims in the private provision of money. With commitment, trust is automatically achieved and competition ensures efficiency. Without commitment, competition plays no role. Trust does play a role but requires a...

How should monetary policy respond to changes in financial conditions? We consider a simple model where firms are subject to shocks which may force them to default on their debt. Firms' assets and liabilities are nominal and predetermined. Monetary policy can therefore affect the real value of...
