Using state of the art mathematical techniques this book provides a complete characterization of the Uzawa-Lucas growth model. In his path-breaking contribution on the 'Mechanics of Economic Growth' Lucas suggested that human capital is the key variable through which technical change is most likely to occur and (by taking some initial intuitions of Uzawa a step further) proposed a two-sector capital accumulation growth model where human capital is allowed to enter a neo-classical-style production structure in multiplicative terms. In this book Paolo Mattana fully explores the dynamic possibilities of the model from both the market and the centralized perspective. A critical evaluation of the inefficiency in the market economy is also provided.

In economics, the emergence of New Growth Theory in recent decades has directed attention to an old and important problem: what are the forces of economic growth and how can public policy enhance them? This book examines major forces of growth--including spillover effects and externalities, education and formation of human capital, knowledge creation through deliberate research efforts, and public infrastructure investment. Unique in emphasizing the importance of different forces for particular stages of development, it offers wide-ranging policy implications in the process. The authors critically examine recently developed endogenous growth models, study the dynamic implications of modified models, and test the models empirically with modern time series methods that avoid the perils of heterogeneity in cross-country studies. Their empirical analyses, undertaken with newly constructed time series data for the United States and some core countries of the Euro zone, show that models containing scale effects, such as the R&D model and the human capital model, are compatible with time series evidence only after considerable modifications and nonlinearities are introduced. They also explore the relationship between growth and inequality, with particular focus on technological change and income disparity. The Forces of Economic Growth represents a comprehensive and up-to-date empirical time series perspective on the New Growth Theory.

This paper examines how relative factor endowments and population growth rates affect growth rates in less developed countries. To answer these questions an extension of the Uzawa-Lucas endogenous growth model is used. The paper proves the existence and uniqueness and of the modified model and illustrates the local stability properties. Significantly the results reverse the conclusions of the only previous attempt to address these issues in the UzawaLucas framework, by Mulligan and Sala-i-Martin (1993), and Barro and Sala-i-Martin (1995). They argue that developing economies will follow a low growth transition path due to a scarcity of human capital. It is shown to the contrary that a standard convergence result applies for economies that have a scarcity of human and physical capital relative to labour. It is also shown that higher unanticipated population growth is consistent with slow transitional growth rates and increases the human capital resources devoted to human capital investments.
