The theoretical framework presented here preserves many of the primary features of the standard neo-classical model, while introducing some modifications that transform it into an open economy endogenous growth model with knowledge accumulation. Knowledge accumulation is determined in part by...

This paper builds on earlier evidence showing that, while most countries exhibit little evidence of unconditional income convergence, countries that trade heavily with one another tend to exhibit a much higher incidence of convergence. Two alternative explanations for the trade-related...

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,...

This paper focuses on the question of income convergence among countries. While the methodology used to determine convergence differs from the common cross-sectional approach, it corroborates Baumol's finding of a convergence club among the world's wealthiest countries. It also shows that there...

This paper examines the relationship between trade and income convergence by focusing on groups of countries comprising major trade partners. The majority of these groups exhibited significant convergence. Furthermore, a comparison of the trade-based groups with different, randomly selected,...

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...

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...
