April 2020Longer-run Economic Consequences of Pandemics
with Òscar Jordà, Alan M. Taylor: w26934
What are the medium- to long-term effects of pandemics? How do they differ from other economic disasters? We study major pandemics using the rates of return on assets stretching back to the 14th century. Significant macroeconomic after-effects of pandemics persist for about decades, with real rates of return substantially depressed, in stark contrast to what happens after wars. Our findings are consistent with the neoclassical growth model: capital is destroyed in wars, but not in pandemics; pandemics instead may induce relative labor scarcity and/or a shift to greater precautionary savings.
January 2020The Long-Run Effects of Monetary Policy
with Òscar Jordà, Alan M. Taylor: w26666
Does monetary policy have persistent effects on the productive capacity of the economy? Yes, we find that such effects are economically and statistically significant and last for over a decade based on: (1) identification of exogenous monetary policy fluctuations using the trilemma of international finance; (2) merged data from two new international historical cross-country databases reaching back to the nineteenth century; and (3) econometric methods robust to long-horizon inconsistent estimates. Notably, the capital stock and total factor productivity (TFP) exhibit strong hysteresis, whereas labor does not; and money is non-neutral for a much longer period of time than is customarily assumed. We show that a New Keynesian model with endogenous TFP growth can reconcile these empirical find...
October 2016Log-linear Approximation versus an Exact Solution at the ZLB in the New Keynesian Model
with Gauti B. Eggertsson: w22784
How accurate is a log-linear approximation of the New Keynesian model when the nominal interest rate is bounded by zero? This paper compares the solution of the exact non-linear model to the log-linear approximation. It finds that the difference is modest. This applies even for extreme events in numerical experiments that replicate the U.S. Great Depression. The exact non-linear model makes the same predictions as the log-linear approximation for key policy questions such as the size and sign of government spending and tax multipliers. It also replicates well known paradoxes like the paradox of toil and the paradox of price flexibility. The paper also reconciles different findings reported in the literature using Calvo versus Rotemberg pricing.

June 2016A Contagious Malady? Open Economy Dimensions of Secular Stagnation
with Gauti B. Eggertsson, Neil R. Mehrotra, Lawrence H. Summers: w22299
Conditions of secular stagnation - low interest rates, below target inflation, and sluggish output growth - characterize much of the global economy. We consider an overlapping generations, open economy model of secular stagnation, and examine the effect of capital flows on the transmission of stagnation. In a world with a low natural rate of interest, greater capital integration transmits recessions across countries as opposed to lower interest rates. In a global secular stagnation, expansionary fiscal policy carries positive spillovers implying gains from coordination, and fiscal policy is self-financing. Expansionary monetary policy, by contrast, is beggar-thy-neighbor with output gains in one country coming at the expense of the other. Similarly, we find that competitiveness policies in...
