Total factor productivity growth in East Asia: A critical survey

This article surveys the recent empirical literature on total factor productivity (TFP) growth in East Asia, and the debate about the sources of growth in the region. It is concluded that: (i) the main merit of this literature is that it has helped focus the attention of scholars on the growth process of East Asia; (ii) the theoretical problems underlying the notion of TFP are so significant that the whole concept should be seriously questioned; (Hi) the TFP growth estimates for the region vary significantly, even for the same country and time period; and (iv) research on growth in East Asia based on the estimation of TFP growth is an activity subject to decreasing returns. If we are to advance in understanding how East Asia grew during the last 30 years we need new avenues of research.

Endogenous Growth, Increasing Returns and Externalities: An Alternative Interpretation of the Evidence

A number of recent papers have used aggregate production functions in an attempt to measure the degree of returns to scale and possible external effects in US manufacturing industries. In this paper I argue that the methods used and the results obtained are deceptive. The reason is that underlying every aggregate production function is the income accounting identity that relates output in value terms to the sum of wages and profits. This identity can be transformed, depending on the empirical paths of the wage and profit rates and of the factor shares, into different mathematical forms which resemble neoclassical production functions. Estimation of these forms, as is done in the literature discussed in the paper, poses serious problems for the interpretation of the results.
