This paper examines business cycles theoretically and empirically, with a quantitative study based on experience over the long run and in a cross section of countries. Several major questions in business cycle theory are explored. Theoretical concerns indicate that the properties of business...

Financial crises have large deleterious effects on economic activity, and as such have been the focus of a large body of research. This study surveys the existing literature on financial crises, exploring how crises are measured, whether they are predictable, and why they are associated with...

Population aging has been linked to a global savings glut and a decline in safe real interest rates. Conversely, risky real returns have not fallen as much, if at all, with equity risk premia on the rise. An existing literature can explain changes in safe rates using demographics. We go further...

Is the effect of monetary policy on the productive capacity of the economy long lived? Yes, in fact we find such impacts are significant and last for over a decade based on: (1) merged data from two new international historical databases; (2) identification of exogenous monetary policy using the...

The risk premium puzzle is worse than you think. Using a new database for the U.S. and 15 other advanced economies from 1870 to the present that includes housing as well as equity returns (to capture the full risky capital portfolio of the representative agent), standard calculations using...

Why did per capita income divergence occur so dramatically during the 19th Century, rather than at the outset of the Industrial Revolution? How were some countries able to reverse this trend during the globalization of the late 20th Century? To answer these questions, this paper develops a...

Are financial crises a negative shock to demand or a negative shock to supply? This is a fundamental question for both macroeconomics researchers and those involved in real-time policymaking, and in both cases the question has become much more urgent in the aftermath of the recent financial...

Interest rates in major advanced economies have drifted down and in greater unison over the past few decades. A country's rate of interest can be thought of as reflecting movements in the global neutral rate of interest, the domestic neutral rate, and the stance of monetary policy. Only the...

Research finds strong links between credit booms and macroeconomic outcomes like financial crises and output growth. Are impacts also seen in financial asset prices? We document this robust and significant connection for the first time using a large sample of historical data for many countries....

Benchmark finance models deliver estimates of bond risk premia based on components of Treasury bond yields. Benchmark macroeconomic models deliver estimates of the natural rate of interest based on growth, inflation, and other macro factors. But estimates of the natural rate implied by the...
