How to Starve the Beast: Fiscal Policy Rules
Countries have widely imposed fiscal rules designed to constrain government spending and ensure fiscal responsibility. This paper studies the effectiveness and welfare implications of expenditure, revenue, budget balance and debt rules when governments are discretionary and prone to overspending. The optimal prescription is either an expenditure ceiling or a combination of revenue and primary deficit ceilings. Most of the benefits can still be reaped with constraints looser than optimal or escape clauses during adverse times. When imposed on their own, revenue ceilings are only mildly ...

Fiscal Dominance
Central banks' resolve and independence are chronically tested by fiscal authorities wishing to impose their desired policies, often leading to socially undesirable economic outcomes. I study how the fiscal and monetary authorities' disagreement over outcomes and their choice of active instruments shape the implementation of policy, dispensing with commitment or first-mover advantage. I characterize the equilibrium for various combinations of active (and correspondingly, passive) instruments, identify which sources of disagreement play a role in each case, and show whether and under what ...

How to Starve the Beast: Fiscal Policy Rules
Countries have widely imposed fiscal rules designed to constrain government spending and ensure fiscal responsibility. This paper studies the effectiveness and welfare implications of revenue, deficit and debt rules when governments are discretionary and profligate. The optimal prescription is a revenue ceiling coupled with a balance budget requirement. For the U.S., the optimal revenue ceiling is about 15% of output, 3 percentage points below the postwar average. Most of the benefits can still be reaped with a milder constraint or escape clauses during adverse times. Imposing a single fiscal ...

Expectations-Driven Liquidity Traps: Implications for Monetary and Fiscal Policy
We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence give rise to persistent liquidity trap episodes. There is no straightforward recipe for enhancing welfare in this economy. Raising the inflation target or appointing an inflation-conservative central banker mitigates the inflation shortfall away from the lower bound but exacerbates deflationary pressures at the lower bound. Using government spending as an additional policy instrument worsens allocations at and away from the lower bound. However, appointing a policymaker who is ...

Monetary Policy, Employment Shortfalls, and the Natural Rate Hypothesis
Activity shortfalls are more costly than strong activity. I consider optimal monetary policy under discretion with an asymmetric (activity shortfalls) loss function. The model satisfies the natural rate hypothesis. The asymmetric loss function and resulting optimal monetary policy exacerbates shortfalls in activity. The additional frequency of activity shortfalls arises from the adjustment of expectations implied by the natural rate hypothesis. The shortfalls asymmetry leads to an inflationary bias, similar to results in the time-consistency literature. Mandating a central bank objective with ...

Conservatism and Liquidity Traps
Appointing Rogoff's (1985) conservative central banker improves welfare if the economy is subject to large contractionary shocks and the policy rate occasionally falls to the zero lower bound (ZLB). In an economy with occasionally binding ZLB constraints, the anticipation of future ZLB episodes creates a trade-off between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy rate is above zero. A conservative central banker mitigates this deflationary bias away from the ZLB, improving allocations both at and away from the ZLB ...

Policy Rules and Large Crises in Emerging Markets
Emerging economies have adopted fiscal and monetary rules to discipline government policy. We study the value and macroeconomic implications of rules and flexibility within a sovereign-default model that incorporates domestic fiscal and monetary policies and long-term external debt. Adopting monetary targets and debt limits during normal times yields welfare gains. Suspending rules can significantly influence policy, macroeconomic outcomes, and welfare during large, unforeseen crises. The gains from flexibility depend on how quickly policymakers are able to reimpose rules after the crisis.

How to Starve the Beast: Fiscal and Monetary Policy Rules
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 public spending and welfare for private agents. However, effective revenue ceilings induce an increase in deficit, debt and inflation. Under many scenarios, including recurrent adverse shocks, the optimal ceiling on U.S. federal revenue is about 15% of GDP, which leads to welfare gains for private ...

Policy Rules and Large Crises in Emerging Markets
Emerging countries have increasingly adopted rules to discipline government policy. The COVID-19 shock lead to widespread suspension and modification of these rules. We study rules and flexibility in a sovereign default model with domestic fiscal and monetary policies and long-term external debt. We find welfare gains from adopting monetary targets and debt limits during normal times. Though government policy cannot itself counteract fundamental shocks hitting the economy, the adoption of rules has a significant impact on policy, macroeconomic outcomes and welfare during large, unexpected ...
