Analysis of decade-long growth rates in all countries shows a striking regularity: episodes of rapid growth are limited largely to a middle range of initial income; neither very poor nor very rich countries experienced rapid growth. Episodes of negative growth are limited to low and middle-income...

The author presents a simple endogenous growth model (with two types of capital) that shows the sizable long-run effects on growth of distortionary policies. The model applies to many different types of distortions of relative prices common in developing countries - for example, price controls,...

After years of poor economic performance, many Latin American countries undertook ambitious programs of macroeconomic stabilization andstructural reform in recent years. This change in policy created high expectations for the region, and some observers have questioned whether actual growth...

Africa's economic history since 1960 fits the classical definition of tragedy: potential unfulfilled with disastrous consequences. The authors use one mehthodology - cross-country regressions - to account for sub-Saharan Africa's growth performance over the past 30 years and to suggest policies...

Soviet growth for 1960-89 was the worst in the world, after controlling for investment and human capital. And relative performance worsens over time. The authors explain the declining Soviet growth rate from 1950 to 1987 by the declining marginal product of capital. The rate of total factor...

The Harrod-Domar growth model supposedly died long ago. But for more than 40 years, economists working on developing countries have applied -and still apply- the Harrod-Domar model to calculate short-run investment requirements for a target growth rate. They then calculate a financing gap...

The authors'study of aid, investment, and policies in Africa leads them to four principal conclusions: 1) The traditional links between aid, investment, and growth are not robust. Aid does not necessarily finance investment and investment does not necessarily promote growth. 2) Differences in...

The authorexamines a range of cross-sectional variation in performance and policies for evidence on what distinguishes successes from failures. At about 6 percent, the growth rate of the Four Tigers - Hong Kong, the Republic of Korea, Singapore, and Taiwan (China) - are among the largest...

The authors suggest that there are important opportunities to empirically evaluate the theoretically predicted channels from policy to growth. They propose a research agenda based on the endogenous growth literature, designed to address the questions: How do national policies affect long-run...
