Policy Paradoxes in the New Keynesian Model
The most common New-Keynesian model--with sticky-prices--has potentially implausible implications in a zero-lower bound environment. Fiscal and forward guidance multipliers can be implausibly large. Moreover, the sticky-price model implies that positive supply shocks, such as an increase in productivity, will lower production, and that increased price flexibility can exacerbate such a decline in output (as well as amplifying the effects of other shocks). These results are fragile and disappear under a plausible alternative to sticky prices--sticky information: Fiscal and monetary multipliers ...

The Multiplier Effect of Education Expenditure
This paper examines the short-run effects of federal education expenditures on local income. We exploit city-level variation in exposure to national changes in the $30-billion Federal Pell Grant Program, which is the largest program to help low-income students attend college in the U.S., to calculate fiscal multipliers of education expenditures. An increase in Pell grants by 1 percent of a city's income raises local income by 2.4 percent over the next two years. This multiplier effect is larger than estimates for military spending (1.5 on average). Multipliers are higher when grants are ...

Reconstruction Multipliers
Following the 2009 L'Aquila earthquake, financing of reconstruction by the Italian central government resulted in a sharp and unanticipated discontinuity in grants across municipalities that were ex-ante very similar. Using the emergency financing law as an instrument, we identify the causal effect of municipal government spending on local activity, controlling for the negative supply shock from the earthquake. In our estimates, this "reconstruction multiplier" is around unity, and we show that the grants provided public insurance. Economic activity contracted in municipalities that did not ...

Debt-dependent effects of fiscal expansions
Economists often postulate that fiscal expansions are less stimulative when government debt is high than when it is low. Empirical evidence, however, is ambiguous. Using a nonlinear neoclassical growth model, we show that the difference in government spending effects between high- and low-debt environments depends on the wealth effect on labor supply and on whether the government uses taxes or spending to retire debt. Because of interrelated state variables, structural VAR estimations conditioning on debt alone can fail to isolate debt-dependent effects. Also, uncertainty on when the ...

Output response to government spending: evidence from new international military spending data
Fiscal policy, among other measures, was widely used to stimulate employment and to put the U.S. economy back on track in response to the Great Recession and in a number of previous recessions in both the United States and in Europe. It is striking how much disagreement there was ? and still is ? among policymakers and academics alike about the inner workings of fiscal policy and its effect on output and employment. Estimating fiscal multipliers is methodologically challenging, as government spending often reacts to current or anticipated changes in economic conditions, and requires bold ...

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 ...

Are the Effects of Fiscal Policy Asymmetric?
Economic research on the size of the fiscal multiplier has assumed that the effects of changes in government spending are symmetric ? that is, they influence economic output to the same degree whether the change is an increase or a decrease. Richmond Fed research indicates that this is not the case; the fiscal multiplier does vary according to the direction of the fiscal action and also varies with the stage of the economic cycle. This finding sheds light on likely outcomes of fiscal policies and helps account for inconsistent estimates of the multiplier in the literature.

Identifying shocks via time-varying volatility
An n-variable structural vector auto-regression (SVAR) can be identified (up to shock order) from the evolution of the residual covariance across time if the structural shocks exhibit heteroskedasticity (Rigobon (2003), Sentana and Fiorentini (2001)). However, the path of residual covariances can only be recovered from the data under specific parametric assumptions on the variance process. I propose a new identification argument that identifies the SVAR up to shock orderings using the autocovariance structure of second moments of the residuals, implied by an arbitrary stochastic process for ...

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 ...
