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...

For decades, the prevailing sentiment among economists was that growth rates remain constant over the long run. Kaldor considered this to be one of the six important 'stylized facts' that theory should address, and until the emergence of endogenous growth models, this was a fundamental feature...

In light of the substantial movement towards trade liberalization during the postwar period, this paper attempts to determine if, and when, countries experienced statistically significant changes in the paths of their export-GDP and import-GDP ratios. We find that: (1) most trade ratios...

Many countries, both industrialized and developing, appear to have experienced a slowdown in economic growth. We examine a large sample of countries and find that a majority exhibit a significant structural break in their post-war growth rates. In nearly all of these cases the break was followed...

This paper examines trends in trade behaviour of 48 countries since the Second World War. In light of the substantial movement towards removal of trade impediments world-wide during the post-war period, this paper attempts to determine if, and when, countries experienced significant changes in...

For decades, the prevailing sentiment among economists was that growth rates remain constant over the long run. Kaldor considered this to be one of the six important `stylized facts' that theory should address, and until the emergence of endogenous growth models, this was a fundamental feature...

Recent literature has documented the sensitivity of unit root tests to failure to account for structural change. This paper reconsiders international evidence on the unit root hypothesis while allowing for two structural breaks. We find evidence of two breaks in three-quarters of the data,...

The hypothesis of exchange rate over shooting is investigated in the context of a model that incorporates activist monetary policy, variable output, imperfect capital mobility, and slow price adjustment. Monetary policy which accommodates prices and/or interest rates is shown to increase the...

An econometric portfolio balance model of an open economy, incorporating exchange rate, price, and current account dynamics, is derived and estimated.The usual stability conditions do not guarantee a unique rational expectations solution, and several proposals for resolving this situation are...

After a decade of generalized floating, it is clear that bilateral exchange rates exhibit more variability than the economic aggregates; relative prices, incomes, and money supplies, that generally comprise the fundamentals of theories of exchange rate determination. Dornbush's over-shooting...
