Unconventional Monetary Policy and Local Fiscal Policy
Following the onset of the pandemic, the Federal Reserve employed an unconventional monetary policy that directly intervened in municipal bond markets. We characterize the fiscal and macroeconomic implications of such central bank actions in a New Keynesian model of a monetary union. We assume that state and local governments are subject to a loan-in-advance constraint, reflecting that with lumpy cash flows, they often finance a fraction of expenditures by issuing short-term bonds. The municipal debt is held by financial intermediaries, who alsosupply credit to the private sector. Direct ...

Fiscal Relief during the COVID-19 Pandemic
In response to the sharp economic downturn during the COVID-19 pandemic, Congress passed unprecedented policy relief measures to support households, businesses, and the broader economy. Compared with previous fiscal stimulus responses, these relief programs have been unmatched in size and scope, speed of response, and novelty of design.Huixin Bi and Chaitri Gulati review recent empirical research on three fiscal relief programs—stimulus checks, augmented unemployment insurance (UI) benefits, and the Paycheck Protection Program (PPP)—to understand their effects on the broader economy as ...

Asset Purchases in a Monetary Union with Default and Liquidity Risks
We develop a nonlinear two-country monetary union model with endogenous sovereign default and financial intermediation to study the effects of targeted asset purchases, and expectations of such programs, during sovereign debt crises. Default risk increases with government debt and shifts in investors’ perceptions of fiscal solvency. We calibrate the model to Italy and Germany during the 2012 European debt crisis; it reproduces key features of the data, including the periphery-core divergence in investment, output, and sovereign yields. Cross-border transmission depends on the ...

U.S. Federal Debt Has Increased, but Appears Sustainable for Now
The unprecedented fiscal stimulus packages that Congress passed earlier this year provided timely assistance to households and businesses, but also led to a sharp increase in U.S. federal government debt. We find that the current net federal debt level of about 100 percent of GDP does not pose a threat to fiscal sustainability. Over a longer horizon, debt sustainability will depend, to a large extent, on whether the federal government can curb mandatory spending or raise taxes.

Fiscal Sustainability: A Cross-Country Analysis
Since the global financial crisis, public debt has risen rapidly in many advanced and emerging market economies. Every country faces a fiscal limit at which taxes and spending can no longer adjust to stabilize debt. But quantifying fiscal limits can be challenging. Different countries have different capacities to service their debt. Moreover, two countries with similar debt levels may face drastically different default risks. {{p}} Huixin Bi introduces a new, country-specific framework of fiscal limits to quantify the maximum level of debt a government can sustain given its economic and ...

Asset Purchases in a Monetary Union with Default and Liquidity Risks
Using a two-country monetary union framework with financial frictions, we quantify the efficacy of targeted asset purchases, as well as expectations of such programs, in the presence of sovereign default and financial liquidity risks. The risk of default increases with the level of government debt and shifts in investors' perception of fiscal solvency. Liquidity risks increase when the probability of default affects the tightness of credit markets. We calibrate the model to Italy during the 2012 European debt crisis and compare it to key features of the data. We find that changes in ...

Sovereign Default and Monetary Policy Tradeoffs
The paper is organized around the following question: when the economy moves from a debt-GDP level where the probability of default is nil to a higher level?the ?fiscal limit?? where the default probability is non-negligible, how do the effects of routine monetary operations designed to achieve macroeconomic stabilization change? We find that the specification of the monetary policy rule plays a critical role. Consider a central bank that targets the risky rate. When the economy is near its fiscal limit, a transitory monetary policy contraction leads to a sustained rise in inflation, even ...

Credit Guarantee and Fiscal Costs
This paper studies the effectiveness of government-backed credit guarantees to the infrastructure sector, a policy tool adopted by a range of countries during recessions. We proposea two-sector model with financial intermediary frictions so that infrastructure producers relyon bank loans to finance their risky production. Governments can intervene in the credit market by providing a partial guarantee on those bank loans. We find that a credit guaranteeincreases infrastructure production, leading to a high fiscal multiplier in the longer run. In thenear term, however, higher wages in the ...

Asset Purchases in a Monetary Union with Default and Liquidity Risks
Using a two-country monetary-union framework with financial frictions, we study sovereign default and liquidity risks and quantify the efficacy of asset purchases. Default risk increases with government indebtedness and shifts in the fiscal limit perceived by investors. Liquidity risks increase when the default probability affects credit market tightness. The framework indicates that shifts in fiscal limits, more than rising government debt, played a crucial role for Italy around 2012. While both default and liquidity risks can dampen economic and financial conditions, the model suggests that ...

Rainy Day Funds Have Grown as State Tax Revenue Strengthens
Many state governments have seen solid growth in their tax revenues over the past couple of years. We show that recent changes in the federal tax code contributed to the uptick in state revenues. In addition, we show that states have used the recent revenue windfall to build up rainy day funds at a much faster pace than they did before the Great Recession.
