Working Paper
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 ...

COVID-19: Fiscal Implications and Financial Stability in Developing Countries
The COVID-19 pandemic has been unlike any other crisis that we have experienced in that it hit all economies in the world at the same time, compromising the risk-sharing ability of nations. At the onset of the pandemic, the World Bank (WB) and the International Monetary Fund (IMF) jointly pledged 1.16 trillion U.S. dollars to help emerging economies deal with COVID-19. Would this amount have been enough to preserve financial stability in a worst case scenario, and what were the fiscal implications of the pandemic? In this article we aim to answer these questions by documenting the size of the ...

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 ...

Assessing the Costs of Rolling Over Government Debt
The US government has $21.4 trillion in outstanding Treasury debt in bills, notes, and bonds. Given the federal funds rate is up 4-5% over the past year, how expensive will it be to roll over maturing Treasury debt at these higher rates?

Recovery of 1933
When Roosevelt abandoned the gold standard in April 1933, he converted government debt from a tax-backed claim to gold to a claim to dollars, opening the door to unbacked fiscal expansion. Roosevelt followed a state-contingent fiscal rule that ran nominal-debt-financed primary deficits until the price level rose and economic activity recovered. Theory suggests that government spending multipliers can be substantially larger when fiscal expansions are unbacked than when they are tax-backed. VAR estimates using data on "emergency" unbacked spending and "ordinary" backed spending confirm this ...

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, ...

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 ...

Fiscal Dominance
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 independence, irrelevant. When the central bank sets the nominal interest rate it renders fiscal impatience (its debt bias) irrelevant, but still faces its expenditure bias. I find that the expenditure bias is about an order of magnitude more severe than the debt bias and has a major impact on welfare ...
