In recent years, the IMF has released a growing number of reports and other documents covering economic and financial developments and trends in member countries. Each report, prepared by a staff team after discussions with government officials, is published at the option of the member country.
This paper analyzes the link between product variety and economic growth. It finds support for the hypothesis that a greater degree of product variety relative to the United States helps to explain relative per capita GDP levels. The paper presents an empirical study for South Africa, which indicates that there exists a stable money demand type of relationship among domestic prices, broad money, real income, and interest rates, as well as a long-term relationship among domestic prices, foreign prices, and the nominal exchange rate.

The empirical analysis in "International R&D Spillovers" (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results reported in Coe and Helpman about the impact of domestic and foreign R&D capital stocks on TFP. In addition, we show that domestic and foreign R&D capital stocks have measurable impacts on TFP even after controlling for the impact of human capital. Furthermore, we extend the analysis to include institutional variables, such as legal origin and patent protection, in order to allow for parameter heterogeneity based on a country's institutional characteristics. The results suggest that institutional differences are important determinants of total factor productivity and that they impact the degree of R&D spillovers.
