Using a recently introduced nonparametric test, I investigate two important and distinct asymmetries in cross-country quarterly macroeconomic time series. Asymmetries are suggested by many theories (old and new), and those discovered aid in the selection of the appropriate nonlinear time series...

Accumulating microeconomic evidence points both to firm level adjustment lumpiness and to the significant influence of idiosyncratic disturbances. Do these matter for aggregate fluctuations, or do their effects largely vanish upon aggregation? This paper explores the implications of local...

This paper re-examines evidence relating mean inflation to cross- sectional inflation asymmetry, and investigates longitudinal asymmetry in disaggregated price series. The asymmetry test used possesses two important characteristics: it has high power, and it is not dominated by outliers. In...
