In this issue, John T. Cuddington and Daniel Jerrett from the Colorado School of Mines examine whether metals prices are in a "super cycle" upswing driven by intensive economic growth in China, in particular. Using evidence from U.S. Social Security records, James E. Duggan, Robert Gillingham, and John S. Greenlees look at the empirical relationship between mortality and lifetime income. Pär Österholm and Jeromin Zettelmeyer analyze the effect of external conditions on growth in Latin America, while Junko Koeda presents a debt overhang model for low-income countries. The issue also includes a comprehensive index for Volume 55 (2008) by author, subject, and title.
This paper examines sources of economic growth in East Asia. The conventional growth-accounting approach to estimating the sources of economic growth requires unrealistically strong assumptions about either competitiveness of factor markets or the form of the underlying aggregate production function. The paper outlines a new approach utilizing nonparametric derivative estimation techniques that does not require imposing these restrictive assumptions. The results for East Asian countries show that output elasticities of capital and labor tend to be different from the income shares of these factors. The paper also explores the compensating potential of private intergenerational transfers.
