Working Paper
The Nonlinear Effects of Fiscal Policy
We argue that the fiscal multiplier of government purchases is nonlinear in the spending shock, in contrast to what is assumed in most of the literature. In particular, the multiplier of a fiscal consolidation is decreasing in the size of the consolidation. We empirically document this fact using aggregate fiscal consolidation data across 15 OECD countries. We show that a neoclassical life-cycle, incomplete markets model calibrated to match key features of the U.S. economy can explain this empirical finding. The mechanism hinges on the relationship between fiscal shocks, their form of ...

The Nonlinear Effects of Fiscal Policy
We argue that the fiscal multiplier of government purchases in incomplete markets models is nonlinear in the spending shock, in contrast to the multiplier in complete markets models and what is assumed in most of the literature. In particular, the multiplier is increasing in the spending shock, with large positive shocks having the largest multiplier and large negative shocks having the smallest multiplier. The mechanism hinges on the relationship between fiscal shocks, their form of financing, and the response of labor supply across the wealth distribution. The model predicts that the ...

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 ...

Sharing Asymmetric Tail Risk: Smoothing, Asset Prices and Terms of Trade
Crises and tail events have asymmetric effects across borders, raising the value of arrangements improving insurance of macroeconomic risk. Using a two-country DSGE model, we provide an analytical and quantitative analysis of the channels through which countries gain from sharing (tail) risk. Riskier countries gain in smoother consumption but lose in relative wealth and average consumption. Safer countries benefit from higher wealth and better average terms of trade. Calibrated using the empirical distribution of moments of GDP-growth across countries, the model suggests non-negligible ...

The Nonlinear Effects of Fiscal Policy
We argue that the fiscal multiplier of government purchases is increasing in the spending shock, in contrast to what is assumed in most of the literature. The fiscal multiplier is largest for large positive government spending shocks and smallest for large contractions in government spending. We empirically document this fact using aggregate U.S. data. We find that a neoclassical, life-cycle, incomplete markets model calibrated to match key features of the US economy can explain this empirical finding. The mechanism hinges on the relationship between fiscal shocks, their form of financing, ...

Downward Nominal Rigidities and Bond Premia
We develop a parsimonious New Keynesian macro-finance model with downward nominal rigidities to understand secular and cyclical movements in Treasury bond premia. Downward nominal rigidities create state-dependence in output and inflation dynamics: a higher level of inflation makes prices more flexible, leading output and inflation to be more volatile, and bonds to become more risky. The model matches well the relation between the level of inflation and a number of salient macro-finance moments. Moreover, we show that empirically, inflation and output respond more strongly to productivity ...
