I study the implications of different institutional frameworks for the conduct of fiscal policy, under the assumption that the government cannot commit to future policy choices. The environments analyzed vary on whether the government is endowed with the ability to commit to beginning-of-period...

We revisit the role of limited commitment in a dynamic risk-sharing setting with private information. We show that a Markov-perfect equilibrium, in which agent and insurer cannot commit beyond the current period, and an infinitely-long contract to which only the insurer can commit, implement...

This paper analyzes dynamic risk-sharing contracts between profit-maximizing insurers and risk-averse agents who face idiosyncratic income uncertainty and may self-insure through savings. We study Markov-perfect insurance contracts in which neither party can commit beyond the current period. We...

Who prevails when fiscal and monetary authorities disagree about the value of public expenditure and how much to discount the future? When the fiscal authority sets debt as its main policy instrument it achieves fiscal dominance, rendering the preferences of the central bank, and thus its...

This paper investigates how institutional constraints discipline the behavior of discretionary governments subject to an expenditure bias. The focus is on constraints implemented in actual economies: monetary policy targets, limits on the deficit and debt ceilings. For a variety of aggregate...

Societies often rely on simple rules to restrict the size and behavior of governments. When fiscal and monetary policies are conducted by a discretionary and profligate government, I find that revenue ceilings vastly outperform debt, deficit and monetary rules, both in effectiveness at curbing...

The fact that money, banking, and financial markets interact in important ways seems self-evident. The theoretical nature of this interaction, however, has not been fully explored. To this end, we integrate the Diamond (1997) model of banking and financial markets with the Lagos and Wright...

We examine the conduct of monetary policy in a world where the supply of outside money is controlled by the fiscal authority-a scenario increasingly relevant for many developed economies today. Central bank control over the long-run inflation rate depends on whether fiscal policy is Ricardian or...
