In contemporary labor economics increasing attention is paid to the fact that unemployment is not only a stock but also a flow phenomenon. The present micro-econometric study analyses the impact of important socio-economic characteristics on unemployment duration in West Germany. Based on a search theoretic framework unemployment duration is considered as a stochastic process whose evolution is influenced by economicand demographic variables like unemployment benefits, expected wage offers, training and age. This is modeled by application of the concept of the hazard rate which denotes the conditional exit rate from unemployment over time given elapsed unemployment duration. Contrasting more traditional models a semi-parametric approachis chosen which reduces the danger of mis-specification of the stochastic duration process. This procedure also is particularly suitable for the analysis of grouped observations on unemployment duration typically generated by longitudinal data sets as the German "Socio-Economic Panel" which is utilized for this study. Besides deriving a set of empirical results on unemployment duration in West Germanymethodological issues of duration analysis are considered with particular attention paid to the impact of the sample design. Also, important outcomes from search theory and findings from other hazard rate analysesare surveyed.

A macroeconomic disequilibrium model is developed for the Federal Republic of Germany. Starting with a microeconomic model of firm's behaviour, the optimal dynamic adjustment of employment and investment is derived. The model of the firm is complemented by an explicite aggregation procedure which allows to derive macroeconomic relations. The model is estimated with macroeconomic data for the Federal Republic of Germany. An important feature is the consistent introduction of dynamic adjustment into a model of the firm. A new method is the particular approach of a delayed adjustment of employment and investment. The estimation results show significant underutilizations of labour and capital and indicate the importance of supply constraints for imports and exports. As the most prominent result, they reveal the importance of the slow adjustment of employment and investment for the macroeconomic situation in Germany and especially for the persistence of high unemployment in the eighties.

The book is concerned with the main issues that arise for general commodity taxation in the internal market: the choice of a new international tax principle and the question of tax rate harmonization. The book provides a thorough discussion of these issues and evaluates the choices made by the European Community from a welfare-theoretic perspective by comparing them to feasible alternatives. The discussion integrates a large number of recent theoretical and policy-oriented contributions which have so far not been collected and summarized in a single volume. Special features of the book are that (a) the analysis combines elements of international trade theory and public finance, two economic disciplines which are rarely integrated; (b) a dual general equilibrium framework is used throughout the analysis, (c) a second-best setting is consistently employed, incorporating relevant policy constraints and integrating conflicting arguments in a single analytical framework, (d) part of the theoretical analysis is supplemented by a computable general equilibrium approach. The book shows that well-known international trademodels can be extended to model alternative principles for taxing international trade but also international differences in preferences for public goods and different views of government behavior - issues which are directly relevant for the discussion of tax rateharmonization but are rarely treated in an analytical way.

This book is the result of five years of research that I carried out as a research fellow at the Faculty of Economics and Econometrics of the University of Amsterdam. The project was initiated in 1986 by Frans van Winden and Roy Thurik. Frans van Winden became interested in self employment through his work concerning government behavior. In the models that he employs, the government is influenced by various social groups, the political strength of which is related to their size. As one of these is the group of self-employed individuals, he became interested in determinants of the size of this group. Roy Thurik was professionally interested in the subject because of his work at the Research Institute for Small and Medium-sized Business in the Netherlands (EIM), an institute that does much research in this area. Together, they wrote a proposal for a research project, for which they received funding from the Dutch Ministry of Economic Affairs . These funds were supplemented by the University of Amsterdam and at a later stage by the Organization for the Advancement of Research in the Economic Discipline (ECOZOEK), that is part of the Netherlands Organization for Scientific Research (NWO). This support is gratefully acknowiedged. The commercial edition of this book was partIy financed by the Centre for Energy Conservation and Environmental Technology (CE), the Center for Research in Experimental Economics and Political Decisionmaking (CREED), and the University of Amsterdam.

Openness and development are key words of central importance in describing the dynamism within the present world economy. Openness denotes the entire process of internationalization and liberalization now underway in the commodity markets, factor markets and financial mar kets. Today there is hardly anational economy or company left which can afIord to ignore international dependencies. In the broadest sense of the word, development encompasses an those dynamic endogenous economic processes which create prosperity and a high standard of living via inno vation and structural change. Modem economic research has shown that both of these fields of economic causalities - which are themselves afIected by a wide variety of interdependencies - detennine the economic destiny of the national economies and of their actors in the industrial, newly industrializing, transitional and developing countries. The present volume focuses on the significance of these two key words while conveying, at the same time, an impression of the broad spectrum of related issues. It contains papers written by economists working at uni versities and research institutes as well as papers submitted by "economic practitioners"; the latter, in particular, provide valuable insights on current issues by taking account of theoretical and practical considerations. Whereas the papers printed in Part I analyze their subjects from a general perspective, the emphasis in Part TI is on specific regional aspects. Part I begins with a theoretical-empirical study on the development of foreign trade.

Oliver Landmann Nobody needs to be convinced of the importance of banking for the Swiss economy. The financial sector grew well above average in the past decade and now accounts for almost 10 % of GDP. Compared to the economy-wide average, it creates more than double as much value added per employee and it is a major contributor to Swiss ex port revenues. But this is no cause for complacency. The industry is subjf:ct to rapid change as the competitive climate has become rougher nationally and internationally. Major structural weaknesses have corne to the surface which raise serious questions about the extent of the required structural adjustments. Thus, banking was an ideal candidate for a major case study in the framework of the National Research Programme No. 28 which is devoted to Switzerland's external economic challenges. The programme was commissioned by the Swiss government and is carried out by the Swiss National Science Foundation. The research project on the fmancial sector was directed by Professors Niklaus Blattner, Hans Genberg and Alexander Swoboda who assembled a team of research economists from the Graduate Institute of International Studies, the International Centre for Monetary and Banking Studies (both at Geneva) and the Labour and Industrial Economics Research Unit at the University of Basel. This joint research effort has yielded an impressive crop of descriptive data, analytical insights and policy-oriented conclusions.

After unification large amounts of money were spent to retrain the East Germany labour force in order to ease the transition to the new market economy. This book uses microeconometric methods and individual data to evaluate the impact of these training programmes on the participants' labour market situation. It discusses the appropriate evaluation methodology as well as the effectiveness of the actual programmes for the individual participants. The empirical results suggest that the public sector sponsored training programmes were fairly ineffective. In contrast, the training organized and paid by the enterprises caused considerable earnings growings.
