International evidence on business cycle duration dependence
We provide an investigation of duration dependence in prewar business expansions, contractions, and whole cycles for France, Germany, and Great Britain. Our results, obtained using both nonparametric and parametric procedures, generally indicate the presence of positive duration dependence in expansions and whole cycles but not in contractions. Our results corroborate those of our earlier studies of the United States.

Have postwar economic fluctuations been stabilized?
Previous investigations of whether the volatility of the U.S. economy diminished after World War II have been inconclusive because of questionable prewar macroeconomic aggregates. We examine, more broadly, the hypothesis of the stabilization of the postwar economy by focusing on the duration of business cycles, rather than their amplitude; in the process, we avoid the debate about the quality of prewar aggregates. Using distribution-free statistics, we find clear evidence of postwar duration stabilization in terms of a shift toward longer expansions and shorter contractions. Moreover, we find ...

On the network topology of variance decompositions: Measuring the connectedness of financial firms
The authors propose several connectedness measures built from pieces of variance decompositions, and they argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. The authors also show that variance decompositions define weighted, directed networks, so that their connectedness measures are intimately-related to key measures of connectedness used in the network literature. Building on these insights, the authors track both average and daily time-varying connectedness of major U.S. financial institutions' stock return volatilities ...
