Jargon Alert on the Fiscal Multiplier
Working Paper
Fiscal Multipliers and Financial Crises
I study the effects of the US fiscal policy response to the Great Recession, accounting both for standard tools and financial sector interventions. A nonlinear model calibrated to the US allows me to study the state-dependent effects of different fiscal policies. I combine the model with data on the fiscal policy response to find that the fall in consumption would have been one-third larger in the absence of that response, for a cumulative loss of 7.18%. Transfers and bank recapitalizations yielded the largest fiscal multipliers through new transmission channels that arise from linkages ...

The Nonlinear Effects of Fiscal Policy
We argue that the fiscal multiplier of government purchases is nonlinear in the size of the spending shock. In particular, the multiplier is increasing in the spending shock, with more expansionary government spending shocks generating larger multipliers and more contractionary shocks generating smaller multipliers. We document that empirically this holds true across time, countries and types of shocks. We then propose a neoclassical mechanism that hinges on the relationship between fiscal shocks, their form of financing, and the response of labor supply across the wealth distribution. A ...

Fiscal Stimulus and Commercial Bank Lending Under COVID-19
We investigate the implications of extra-normal government spending under the COVID-19 pandemic for commercial bank lending growth between 2019Q4 and 2020Q4 in a large sample of over 3000 banks from 71 countries. We control for pre-pandemic structural factors, bank characteristics and government debt. To address the likely endogeneity of government assistance under the pandemic, we instrument for extra-normal spending using disparities in pre-existing national political characteristics for identification. Our results indicate that while higher government spending was associated with higher ...

The Macroeconomic Effects of Cash Transfers: Evidence from Brazil
This paper provides new evidence on the macroeconomic impact of cash transfers in developing countries. Using a Bartik-style identification strategy, the paper documents that Brazil’s Bolsa Familia transfer program leads to a large and persistent increase in relative state-level GDP, formal employment, and informal employment. A state receiving 1% of GDP in extra transfers grows 2.2% faster in the first year, with R$100,000 of extra transfers generating five formal-equivalent jobs, half of which are informal. Consistent with a demand-side mechanism, the effects are concentrated in ...

State-Dependent Local Projections: Understanding Impulse Response Heterogeneity
An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response’s heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local projection specification that nevertheless keeps the model linear in parameters. Using our new decomposition-based approach, we show how to unpack heterogeneity in the fiscal multiplier, an object that at any point in time may depend on a number of potentially correlated factors, including existing ...

Understanding Heterogeneous Agent New Keynesian Models: Insights from a PRANK
In recent years there has been a lot of interest in the effect of income inequality (heterogeneity) on the economy, from both academics and policymakers. Researchers have developed Heterogeneous Agent New Keynesian (HANK) models that incorporate heterogeneity and uninsurable idiosyncratic risk into the New Keynesian models that have become a cornerstone of monetary policy analysis. This research has argued that heterogeneity and idiosyncratic risk change many features of New Keynesian models – the transmission of conventional monetary policy, the forward guidance puzzle, fiscal multipliers, ...
Working Paper
Small and orthodox fiscal multipliers at the zero lower bound
Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian literature is that the answer is yes. New evidence provided here suggests that the answer is often no. For a broad range of empirically relevant parameterizations of the Rotemberg model of costly price adjustment, the government purchase multiplier is about one or less, and the response of hours to a tax cut is either negative or close to zero.

I study the effects of the US fiscal policy response to the Great Recession, accounting both for standard tools and financial sector interventions. A nonlinear model calibrated to the US allows me to study the state-dependent effects of different fiscal policies. I combine the model with data on the fiscal policy response to find that the fall in consumption would have been almost 50% larger in the absence of that response for a cumulative loss of 7.18%. Transfers and bank recapitalizations yielded the largest fiscal multipliers through new transmission channels that arise from linkages ...
Working Paper
Fiscal Multipliers and Financial Crises
What type of fiscal policy is most effective during a financial crisis? I study the macroeconomic effects of the US fiscal policy response to the Great Recession, accounting not only for standard tools such as government purchases and transfers but also for financial sector interventions such as bank recapitalizations and credit guarantees. A nonlinear quantitative model calibrated to the US allows me to study the state-dependent effects of different types of fiscal policies. I combine the model with data on the US fiscal policy response to find that the fall in aggregate consumption would ...
