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 ...

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 ...

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 ...

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, ...

Lottery Loans in the Eighteenth Century
In the 18th century Britain frequently issued lottery loans, selling bonds whose size was determined by a draw soon after the sale. The probability distribution was perfectly known ex-ante and highly skewed. After the draw the bonds were identical (except for size) and indistinguishable from regular bonds. I collect market prices for the lottery tickets and show that investors were paying a substantial premium to be exposed to this purely artificial risk. I show that investors were well-to-do and included many merchants and bankers. I turn to cumulative prospect theory to make sense of these ...

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.

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?

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 ...
