The initial purposes of this book were to update and extend the discussion and the results presented ill our previous book, The Labor Market and Business Cycle Theories. Our 1990 article, which appeared in The Journal of Economic Behavior and Organization, represented a first step in this direction. The consequences of this effort have materialized in a number of new chapters that has led de facto to a new book, in which the surviving parts have been largely revised. The 1989 book was too mathematically oriented for many Keynesians and post Keynesians to be fully appreciated and insufficiently microfounded for both new classicals and new-Keynesians to be warmly accepted, yet we received positive and encouraging comments, and it was sold out very quickly. It was an attempt to dis cuss dynamics in Keynesian terms, based on a double assumption that maintains its validity-that both economic facts and analytical and methodological innova tions had contributed to a renewed interest in business cycles, which over time has had its "ups and downs." Since then, many more articles and books have appeared, stressing in particular the role of microfoundations and of nonlinearities in shaping business cycle theory.

The title Social Economics describes a range of questions that preoccupy economists, sociologists, and political theorists alike: are the laws of economics 'law of life'? To what extent are individuals governed by economic motives when they make decisions about where they live, how they live, the size of their families, and above all, the way they treat their fellow men and women? The essays in this volume show how economic theory can increase the understanding of issues that affect all our lives.

Experimental Economics has experienced a steadily growing interest by economists during the last decade. This may not surprise since laboratory and field experiments obviously provide a further valuable source of empirical evidence of economic behavior besides statistics, econometrics, polls, interviews and simulations. In an overview of the recent developments in Experimental Economics, the present book concentrates on three central themes standing in the actual research focus: bargaining, cooperation and election markets. For each one of these topics the volume presents several state-of-the-art survey articles by experts in the field, accompanied by detailed comments. While the experimental approach sheds new light on the microeconomic standard topics of bargaining and cooperation, the election market approach as a new field may provide better forecasts for political elections - and for soccer World Championships.

There are many issues relating to the new economy in Europe and the USA that are unexplored. Here, the authors present innovative theoretical and empirical analysis on Internet dynamics, productivity growth and organizational changes in selected OECD countries. New empirical findings related to telecommunications, Internet and growth also are presented. Based on the theoretical and empirical analyses, various policy options are developed. Policy measures, both at the regional and national levels, can stimulate structural change, knowledge diffusion and economic growth. Different governance strategies for the Internet and e-commerce are identified from a global perspective.
