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 prone to overspending. 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 ...

Fiscal Dominance
Central banks' resolve and independence is 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 ...

Real Interest Rates, Inflation, and Default
This paper argues that the comovement between inflation and economic activity is an important determinant of real interest rates over time and across countries. First, we show that for advanced economies, periods with more procyclical inflation are associated with lower real rates, but only when there is no risk of default on government debt. Second, we present a model of nominal sovereign debt with domestic risk-averse lenders. With procyclical inflation, nominal bonds pay out more in bad times, making them a good hedge against aggregate risk. In the absence of default risk, procyclical ...

How Much Debt Does the U.S. Government Owe?
The U.S. government is often referred to as the world?s biggest debtor. But how much debt does it owe? A visit to the website of the U.S. Department of the Treasury yields a bewildering array of different measures of U.S. federal government debt. Although the gross debt of the U.S. federal government is approaching $18 trillion, the debt that is subject to the debt limit is a few billion dollars smaller, while debt in the hands of the public is less than $13 trillion.

Government Debt, Limited Foresight, and Longer-term Interest Rates
We study the relationship between government debt and interest rates in an environment where financial market participants have limited foresight about the future path of government debt. We show that limited foresight substantially attenuates estimates of the effect of government debt on longer-term yields relative to the benchmark of rational expectations often used in empirical analysis.

Is Inflation Default? The Role of Information in Debt Crises
We consider a two-period Bayesian trading game where in each period informed agents decide whether to buy an asset ("government debt") after observing an idiosyncratic signal about the prospects of default. While second-period buyers only need to forecast default, first-period buyers pass the asset to the new agents in the secondary market, and thus need to form beliefs about the price that will prevail at that stage. We provide conditions such that coarser information in the hands of second-period agents makes the price of debt more resilient to bad shocks not only in the last period, but ...

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 ...

The Economic Impact of COVID-19 around the World
This article provides an account of the worldwide economic impact of the COVID-19 shock. In 2020, it severely impacted output growth and employment, particularly in middle-income countries. Governments responded primarily by increasing expenditure, supported by an expansion of the supply of money and debt. These policies did not put upward pressure on prices until 2021. International trade was severely disrupted across all regions in 2020 but subsequently recovered. For 2021, we find that the adverse effects of the COVID-19 shock on output and prices were significant and persistent, ...

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 ...
