This paper proposes a new panel unit root test based on Simes' [Biometrika 1986, An Improved Bonferroni Procedure for Multiple Tests of Significance'] classical intersection test. The test is robust to general patterns of cross-sectional dependence and yet straightforward to implement, only...

This paper examines the sources of stickiness in aggregate consumption growth. We first derive a dynamic consumption equation which encompasses many recent developments in consumption theory: habit formation, intertemporal substitution effects, consumption based on current income, and...

We investigate the cyclicality of the private savings to GDP ratio for a panel of 19 OECD countries over the period 1971-2009. We find robust evidence that the private savings ratio is countercyclical. Three theories unambiguously predict a higher private savings ratio during recessions: a...
