Are Negative Supply Shocks Expansionary at the Zero Lower Bound? Revise and Resubmit at Journal of Political Economy
Abstract: Standard sticky-price models predict that temporary, negative supply shocks are expansionary at the zero lower bound (ZLB) because they raise inflation expectations and lower expected real interest rates, which stimulates consumption. This paper tests that prediction with oil supply shocks, an earthquake, and inflation risk premia, demonstrating that negative supply shocks are contractionary at the ZLB despite also lowering expected real interest rates. These findings are rationalized in a model with financial frictions, where negative supply shocks reduce asset prices and net worth, translating into larger borrowing spreads so that consumption contracts. In this data-consistent model fiscal stimulus at the ZLB is substantially less effective than in standard sticky-price models.

Financial Dampening (updated 2/2015), with Mu-Jeung Yang
Abstract: We propose a novel mechanism, “financial dampening,” whereby financial sector deleveraging attenuates the effectiveness of monetary policy. In our model of financial intermediation, where banks have leverage targets and asymmetric portfolio adjustment costs, deleveraging banks will have a lower pass-through from reductions in policy rates to credit supply. We find consistent evidence for financial dampening in micro-data on U.S. regulated financial intermediaries. We instrument deleveraging at local banks using average deleveraging at spatially-separate banks of the same bank holding company to isolate local deleveraging independent of local demand conditions. We find that in response to a 1% monetary policy shock, a bank at the 25th percentile of the deleveraging distribution increases its loan growth by 3.70% more than a bank at the 75th percentile according to our baseline specification. Thus, our mechanism provides a rationale for why recoveries from financial crises may be slow.

Fiscal Multipliers at the Zero Lower Bound: International Theory and Evidence.
Abstract: Can fiscal policy be effective in an open economy with flexible exchange rates? Standard open economy models suggest that the open economy fiscal multiplier is small when exchange rates are flexible. This paper reassesses this premise by explicitly incorporating the zero lower bound (ZLB) on nominal interest rates in a small open economy New Keynesian model. It finds (1) when the ZLB binds and uncovered interest rate parity (UIP) holds, then the open economy fiscal multiplier is larger than 1 and bigger than the closed economy fiscal multiplier, (2) these conclusions can be reversed given significant violations of UIP, and (3) for estimated departures from UIP, the open economy fiscal multiplier at the ZLB is above 1 but smaller than the closed economy fiscal multiplier.

Supply-side policies in the Depression: Evidence from France With Jeremie Cohen-Setton and Joshua Hausman
Abstract: In 1936, France enacted supply-side restrictions, in particular wage increases and a 40-hour week law. The result was stagflation. Output rose after France devalued in September 1936, but then fell as the 40-hour law took full effect. Inflation rose rapidly. Using panel data on sectoral output, we find that in affected industries, the 40-hour law reduced production. Since stagnant output coincided with a large decline in real interest rates, the French experience fits neither the standard one-sector new Keynesian model nor a two-sector model calibrated to match the cross-sectional data. We propose an alternative, disequilbrium model consistent with expansionary effects of lower real interest rates and contractionary effects of higher real wages. Both this model and our empirical evidence suggest that without supply-side problems, France would have recovered rapidly after leaving the Gold Standard.
