The past approach to the international debt crisis has been traditionally based on conventional banking principle in which debt had to be paid back in fuH and in time. International lending was a function of the perceived credit standing of debtor country and the return on investment (ROI). If debtor country run into difficulties and had problems with service payments - it was generally assumed that the debt-related expenditures were mismanaged. With economic stability and firm financial rules - the debt crisis was supposed to disappear after application of appropriate adjustment measures. However in the world of inconsistent lending criteria greater uncertainty and increased volatility of expectations - the problem has continued to get worse. At the beginning of the 1990s a number of countries are more indebted than at any other time in the past. Until mid 1980s extern al debt economics has been rather a disembodied concept for most economists and business leaders. The main reason for this neglect of one of the most important macroeconomic categories was difficulty of distinguishing terminologically and methodologically the domestic determinants of national expenditures from the external ones. Then there were conceptual problems in distinguishing the functional determinants of macroeconomic liquidity from external and domestic determinants of macro-economic solvency. Moreover many studies of the debt crisis were one-sided. Usually debt was seen as a 'white-black' phenomenon with debtor countries accusing creditor countries for causing the crisis and vice versa.

European central bank policy is already taking place today in an informal way. It comprises, in short, European exchange rate management and interest rate policy decisions within and without the European Monetary System (EMS). A focal point of such policy actions are the money market operating targets of European Central Banks. Those central bank policies appear to be dominated, however, by the Deutsche Bundesbank. This has caused recurring critical discussion of European asymmetries and German leadership in monetary stabilization pOlicies, before and after the EMS turbulences of September 1992. However, it should be pointed out that German dominance has increasingly evolved in a cooperative way, ever since the Committee of European Central Bank Governors began to meet regularly in 1964; the Basle-Nyborg accord of 1987 formed a further stage of cooperative efforts within the EMS. Presently, a small group of countries (including Benelux and Austria) generally follows, after prior 'concertation', German monetary policy patterns. In this narrow sense, there exists a European central bank policy within a "Deutsche-Mark-Zone". In a broader sense, European central bank policy is shaped, after proper consultation, by monetary cooperation between the larger EMS countries, but once again dominantly influenced by Germany; recent problems of highjnterest rates in France and elsewhere due to (relative) restrictive German monetary pOlicies are striking examples. German monetary dominance, in the narrow or broad sense, obviously creates, in the long-run, an untenable situation in the eyes of European partner countries.

This volume discusses some economic aspects of immigration with special refer ence to the case of Germany. Immigration has become a major issue in Germany. Germany still does not have an official immigration policy in spite of the fact that more than 8 percent of the residents are non-citizens and that Germany · s immigration figures almost have reached the US figures. The foreign Iabor supply strongly influences the German Iabor market. The bulk of foreign workers is employed in certain industries. In some industries (mining, steel) 20 and more percent of the employees are foreign workers. Most foreign workers are blue collar workers with low wages. The Iabor demand for immigrants has declined in the last 15 years while the foreign population and Iabor supply has increased. As a consequence, foreigners experience higher unemployment rates than Germans. The fall of the Berlin wall and the collapse of the communist regimes in East Europe further increased the blue collar Iabor supply and strengthened the competition for foreign workers on the German Iabor market.

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.

Two areas have fascinated me for a long time. One is the micro economic theory of consumer behavior, the other one the role of space in economic processes. Usually, the two don't go together very well. In more advanced versions of microeconomic consumer theory its economic actor may face uncertainty, have to allocate resources over time, or have to take into ac count the characteristics of products, but rarely deals with space. He/she inhabits a spaceless point economy. Regional Science, on the other hand, describes and analyzes the spatial structure and development of the econ omy, but either ignores individual decision making altogether or treats it in a rather simplistic way. In this book I try to bring together these two areas of interest of mine. I do this by use of the microeconomic concept of search and placing it in an explicit spatial context. The result, in my opinion, is a theoretical concept with fascinating implications, a broad set of potential implications, and numerous interesting research questions. After reading this book, where I layout the basic idea of spatial search, describe its elements, and discuss some of its implications, I hope the reader will share this opinion. There are still plenty of unanswered research questions in this part of economic theory. Hopefully, this book will stimulate more work along these lines.

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.

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.

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.

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.

High and persistent unemployment rates in Europe during the eighties gave rise to a lively discussion about the nature and causes of joblessness. Among other sources structural unemployment was blamed for the lack of response of unemployment to increasing aggregate demand. Renewed attention was thus devoted to an analysis of the magnitude and the development of structural unemployment as well to its possi ble determinants. In this literature, the Beveridge curve experienced a resurrection and, at first glance, it seemed to be an appropriate tool to analyse the aforementioned issues. However, it was soon recognized that the Beveridge curve, i. e. the relation between unemployment and vacancies, was anything but stable, thus requiring a care ful distinction between dynamic loops around a (stable?) long-run Beveridge curve and possible shifts due to, say, an increasing mismatch between labor supplied and demanded. The controversy is far from being settled at the time of this writing. This book contains a collection of hitherto unpublished papers which are devoted to a theoretical and econometric analysis of structural unemployment. The papers put considerable emphasis on the question to what extent the Beveridge curve can serve as an adequate tool for such studies. The countries under consideration are Germany and Austria. In what follows a very brief summary of each paper will be outlined. Franz and Siebeck present, at some length, a theoretical and econometric analysis of the Beveridge curve in Germany.
