Policies to encourage more open trading and accumulation of human capital may be as important to growth and technological change as additional foreign lending.

There is substantial research about cross section and time series correlations between economic growth and various economic, social, demographic and political variables. After analyzing these correlations, the paper makes the following conclusions. Exogenous increases do not seem to cause increases in the rate of technological change, but instead seem to be associated with lower rates of return to capital. Increased openness to international trade speeds up growth and technological change as do an increase in scientists and engineers. Countries more open to trade have a higher level of investment and capital growth - which is not associated with a fall in the marginal product of capital. Countries that become more integrated with world markets seem to have a higher marginal product of capital. Increases in capital investment associated with a higher per capita GDP are associated with a fall in the marginal product of capital. Increases in capital investment associated with increases in trade are not. This suggests that policies to encourage more open trading may be as important to growth as additional foreign lending - especially in their cumulative effects - and at the same time enhance the efficient use of foreign loans.

In this wide ranging exposition of the various economic theories of technological change, Stanislaw Gomulka relates them to rates of growth experienced by different economies in both the short and the long term. Analysis of countries as diverse as Japan, the Soviet Union and the United Kingdom demonstrates that there is an interdependence between technological change and the institutional and cultural characteristics of different countries, which can have a profound effect on their rates of growth. All of the major, relevant models are discussed, including those of Kuznets and Phelps, but throughout the emphasis is on the creation of a unified theoretical framework to help explain the impact of technological progress on both a micro and a macro scale.

A Brookings Institution Press and British-North American Committee publication Two hundred years ago, the first Industrial Revolution sparked a dramatic acceleration in the quantity of goods and services available to the average citizen--a trend of steadily increasing real income per capita that continues to this day. Since that time, economists have struggled to develop systematic explanations for what caused the sudden, rapid increase, why the economy keeps growing, and why the rate of growth varies in different time periods and nations. In this book, F. M. Scherer traces the evolution of economic growth theory from the Industrial Revolution to the present. Emphasizing technological change as the most crucial dynamic force for growth, Scherer analyzes early hypotheses that paid little attention to new technologies, follows the emergence of theories that increasingly emphasized technological change, and reviews the current state of economic growth theory. Pointing out a lack of solid microbehavioral foundations to support contemporary "new growth" ideas, Scherer then supplies some foundational "bricks" concerning financial investment and human capital, and concludes by exploring the prospects for sustaining rapid growth into the next century.

Growth in a Time of Change: Global and Country Perspectives on a New Agenda is the first of a two-book research project that addresses new issues and challenges for economic growth arising from ongoing significant change in the world economy, focusing especially on technological transformation. The project is a collaboration between the Brookings Institution and the Korea Development Institute. Part I of the book looks at key elements of change from a global perspective. It analyzes how technological change, shifts in investment, and demographic transition are affecting potential economic growth globally and across major groups of economies. The contributors explore possible scenarios for the global economy as the digital revolution drives rapid technological change, including impacts on growth, jobs, income distribution, trade balances, and capital flows. Technology is changing the global configuration of comparative advantage and globalization increasingly has a digital dimension. The implications of these developments for the future of sectors such as manufacturing and for international trade are assessed. Part II of the book addresses new issues in the growth agenda from the perspective of an individual major economy: South Korea. The chapters in this section analyze how macroeconomic developments and technological change are influencing the behavior of households and firms in terms of their decisions to consume, save, and invest. Rising income and wealth inequalities are a major concern globally. Against this backdrop, trends in the labor income share and wage inequalities in South Korea are analyzed in terms of the role played by technology, industrial concentration, shifts in labor demand and supply, and other factors. Throughout the book, the contributors, in their analysis of both global and Korea-specific trends and prospects, place emphasis on drawing implications for policy.

Much is written in the popular literature about the current pace of technological change. But do we have enough scientific knowledge about the sources and management of innovation to properly inform policymaking in technology dependent domains such as energy and the environment? While it is agreed that technological change does not 'fall from heaven like autumn leaves,' the theory, data, and models are deficient. The specific mechanisms that govern the rate and direction of inventive activity, the drivers and scope for incremental improvements that occur during technology diffusion, and the spillover effects that cross-fertilize technological innovations remain poorly understood. In a work that will interest serious readers of history, policy, and economics, the editors and their distinguished contributors offer a unique, single volume overview of the theoretical and empirical work on technological change. Beginning with a survey of existing research, they provide analysis and case studies in contexts such as medicine, agriculture, and power generation, paying particular attention to what technological change means for efficiency, productivity, and reduced environmental impacts. The book includes a historical analysis of technological change, an examination of the overall direction of technological change, and general theories about the sources of change. The contributors empirically test hypotheses of induced innovation and theories of institutional innovation. They propose ways to model induced technological change and evaluate its impact, and they consider issues such as uncertainty in technology returns, technology crossover effects, and clustering.
