Provides evidence of a problem with the influential testing and assessment of Solow¿s (1956) growth model proposed by Mankiw et al. (1992) and a series of papers evaluating the latter. First, the assumption of a common rate of technical progress maintained by Mankiw et al. (1992) is relaxed. Solow¿s model is extended to include the different levels and rates of technical progress of each country. This increases the explanatory power of the cross-country variation in income/capital of the OECD countries to over 80%. The estimates of the parameters are statistically significant and take the expected values and signs. Second, the estimates merely reflect a statistical artifact. This has serious implications for the possibility of actually testing Solow¿s growth model. Illus.

International Debt Statistics (IDS), a long-standing annual publication of the World Bank, features external debt statistics and analysis for the 120 low- and middle-income countries that report to the World Bank Debtor Reporting System. IDS 2021 includes (1) an overview analyzing global trends in debt stocks of and debt flows to low- and middle-income countries within the framework of aggregate capital flows (debt and equity); (2) a feature story on the World Bank and International Monetary Fund Debt Service Suspension Initiative in response to the COVID-19 pandemic; (3) tables and charts detailing debtor and creditor composition of debt stock and flows, terms of new commitments, and maturity structure of future debt service payments and debt burdens, measured in relation to gross national income and export earnings for each country; (4) one-page summaries per country, plus global, regional, and income group aggregates showing debt stocks and flows, relevant debt indicators, and metadata for six years (2009 and 2015†“19); and (5) a user guide describing the tables and content, definitions and rationale for the country and income groupings used in the report, data notes, and information about additional resources and comprehensive data sets available to users online. Unique in its coverage of the important trends and issues fundamental to the financing of low- and middle-income countries, IDS 2021 is an indispensable resource for governments, economists, investors, financial consultants, academics, bankers, and the entire development community.

The measurement of willingness to pay for electricity relies critically on a reliable estimate of the demand for electricity function. Empirical work tends to assume that the demand for electricity has no satiation point. Many electricity demand models assume a constant price elasticity, which implies infinite demand at low prices. This report proposes a plausible functional form for the demand of electricity. The proposed functional form is consistent with two properties of electricity demand functions for households & firms, namely, the negative relationships between price & quantity, & the finiteness of demand at zero price. The report also demonstrates that this functional form of the demand function leads to easily estimable economic benefits of electricity.

Attempts to measure competitiveness (CP) across countries have typically neglected the world¿s smallest economies. Hence, a simple composite index, the Small State Manufactured Export CP Index or SSMECI, was developed to benchmark industrial CP. The SSMECI represents the first attempt to provide a comprehensive picture of the CP performance of small states. The performance of small states varies across geographical regions, income groups, & country size classes. High-performing small states had better macroeconomic conditions, higher levels of foreign invest., more trade openness, better levels of educ., & modern infrastructure. A coherent, market-oriented CP strategy in small states is vital to success on international markets. Tables.

This paper reviews the history & progress of understanding development theory over the past 50 years. Development thinking has evolved from an early paradigm that focused on savings & capital investment to subsequent arguments favoring the inclusion of human capital, policy, technical change, & finally to the inclusion of the role of institutions, & good governance. Secure property rights in the broadest sense, which are applicable to all resources & not just land, are particularly important to realize investment yield. This evolution of development thought describes a conceptual framework that can guide development practitioners in prioritizing, sequencing, & characterizing all interventions aimed at reducing poverty.
