In this issue, a team of economists look at approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or permanent phenomenon. Era Dabla-Norris and Gabriela Inchauste examine what drives the growth of firms, with a focus on informality and regulations. Evan Tanner and Issouf Samake use a vector autoregression approach to examine the probabilistic sustainability of public debt in Brazil. Mexico, and Turkey. And Rachel Glennerster and Yongseok Shin ask whether transparency pays?that is, does the frequency and accuracy of macroeconomic information released to the public lead to lower borrowing costs in sovereign debt markets?

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.
