This paper provides evidence on the unit root hypothesis and long-term growth by allowing for two structural breaks. We reject the unit root hypothesis for three-quarters of the countries approximately 50% more rejections than in models that allow for only one break. While about half of the...

This paper investigates the possibility, raised by Perron (1989, 1990a), that aggregate economic time series can be characterized as being stationary around broken trend lines. Unlike Perron, we treat the break date as unknown a priori. Asymptotic distributions are developed for recursive,...

This study quantifies the importance of a Global Financial Cycle (GFCy) for capital flows. We use capital flow data dis-aggregated by direction and type between 1990Q1 and 2015Q5 for 85 countries, and conventional techniques, models and metrics. Since the GFCy is an unobservable concept, we use...

We estimate channels of international risk sharing between European Monetary Union (EMU), European Union, and other OECD countries 1992-2007. We focus on risk sharing through savings, factor income flows, and capital gains. Risk sharing through factor income and capital gains was close to zero...

This paper shows that general equilibrium effects can partly rationalize the high correlation between saving and investment rates observed in OECD countries. We find that once controlling for general equilibrium effects the saving-retention coefficient remains high in the 70's but decreases...

Despite enormous growth in international capital flows, capital-output ratios continue to exhibit substantial heterogeneity across countries. We explore the possibility that taxes, particularly corporate taxes, are a significant source of this heterogeneity. The evidence is mixed. Tax rates...

We develop an equilibrium model in which exchange rates, stock prices and capital flows are jointly determined under incomplete forex risk trading. Incomplete hedging of forex risk, documented for U.S. global mutual funds, has three important implications: 1) exchange rates are almost as...

The evidence and analysis in this paper support the earlier findings of Feldstein and Horioka (1980) that sustained increases in domestic savings rates induce approximately equal increases in domestic rates of investment. New estimates for the post-OPEC period 1974-79 imply that each extra...

This paper reviews the extent and policy implications of linkages between demographic changes and international factor mobility. Evidence is found of significant demographic effects on both migration and the current account, but for different reasons neither increased migration nor international...
