Social Capital in the Creation of Human Capital

This paper examines whether the Solow growth model is consistent with the international variation in the standard of living. It shows that an augmented Solow model that includes accumulation of human as well as physical capital provides an excellent description of the cross-country data. The paper also examines the implications of the Solow model for convergence in standards of living, that is, for whether poor countries tend to grow faster than rich countries. The evidence indicates that, holding population growth and capital accumulation constant, countries converge at about the rate the augmented Solow model predicts. This paper takes Robert Solow seriously. In his classic 1956 article Solow proposed that we begin the study of economic growth by assuming a standard neoclassical production function with decreasing returns to capital. Taking the rates of saving and population growth as exogenous, he showed that these two vari- ables determine the steady-state level of income per capita. Be- cause saving and population growth rates vary across countries, different countries reach different steady states. Solow's model gives simple testable predictions about how these variables influ- ence the steady-state level of income. The higher the rate of saving, the richer the country. The higher the rate of population growth, the poorer the country. This paper argues that the predictions of the Solow model are, to a first approximation, consistent with the evidence. Examining recently available data for a large set of countries, we find that saving and population growth affect income in the directions that Solow predicted. Moreover, more than half of the cross-country variation in income per capita can be explained by these two variables alone. Yet all is not right for the Solow model. Although the model correctly predicts the directions of the effects of saving and

A Contribution to the Empirics of Economic Growth

Large sample properties of generalized method of moments estimators

Growth in this model is driven by technological change that arises from intentional investment decisions made by profit-maximizing agents. The distinguishing feature of the technology as an input is that it is neither a conventional good nor a public good; it is a nonrival, partially excludable good. Because of the nonconvexity introduced by a nonrival good, price-taking competition cannot be supported. Instead, the equilibrium is one with monopolistic competition. The main conclusions are that the stock of human capital determines the rate of growth, that too little human capital is devoted to research in equilibrium, that integration into world markets will increase growth rates, and that having a large population is not sufficient to generate growth.

Internal migration in developing countries

Studies in Business-Cycle Theory

This report evaluates the evidence on how migration may promote or hinder development in countries of origin, and explores possible win-win solutions for both sending and receiving countries. The analysis of recent OECD data of foreign-born nationals into Europe documents the presence of multiple migration patterns and reveals that the EU lags significantly behind the United States in attracting highly-skilled migrants who originate mostly from Africa. Reviewing the analytical and empirical evidence on the economic and social costs and benefits of migration and remittances for sending countries reveals that migration can generate substantial direct and indirect gains for sending countries via employment generation, human capital accumulation, remittances, diaspora networks and return migration. Policy coherence across various policies including migration, trade, investment and development cooperation can augment these gains. Major challenges for EU policymaking to maximise the gains from migration for both sending and receiving countries could include better management of migration and human resources, smart visa policies to facilitate circular migration and greater synergies between migration and development assistance programmes in the context of poverty reduction strategy initiatives.

Effects of Migration on Sending Countries: What Do We Know?

This accessible and topical book offers invaluable insights to policy makers in both industrialized and developing countries as well as to scholars and researchers of economics, development, international relations and to specialists in migration.

International Migration and Economic Development

This paper proposes a model to describe the evolution of real gross domestic product (GDP) in the world economy that is intended to apply to all open economies. The parameters of the model are calibrated using evidence from Sachs and Warner on economies classed as open, from Parente and Prescott on economies that have successfully begun to develop, and from Kuznets and the World Bank on the employment share of agriculture in various times and places. The theory predicts convergence of the income levels and growth rates in the open economies and has strong but reasonable implications for transition dynamics. (JEL F41, O33, O47)
