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.
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.
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.

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.
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.

The recent development of endogenous growth theories has renewed the in terest into the sources of productivity growth of the advanced industrialized economies. The basic advance of these models is that the evolution of tech nological progress is explained endogeneously within the economic model. The most important concept is the idea of endogenous, market-driven inno vations which are seen as the basic source of technological advances. Firms develop sophisticated production techniques and new products in order to reduce costs or to stimulate demand. Equally important is the concept of knowledge spillovers from innovation activities and scale economies associ ated with them. External effects drive a wedge between private and social re turns of innovation activities, and scale economies affect the market structure. In addition, each year's productivity increases exhibit an enormous social value. Therefore, the analysis of endogenous innovations, scale economies, and knowledge spillovers has important implications for economic policy which enhances the interest into empirical investigations of these issues. This book is a collection of theoretical and empirical work on this subject. It combines micro economic and macroeconomic issues; a special emphasis is placed on empirical applications. Much work has been devoted to the search and the preparation of appropriate data, and all models are estimated with panel data. The first two chapters take an aggregate view at the growth process.
In this book on disequilibrium, growth and labor market dynamics we take predominantly a macroeconomic perspective. We present a working model that can easily be varied in different directions in order to subsume innovations in the literature on macroeconomics, old and new, and to contribute to important currently discussed macroeconomic issues. Our working model is set up in a way that there is a close relationship between our presented dynamic models and modern macro econometric models with disequilibrium both in the labor and the goods markets. One of our objectives is, therefore, to narrow the gap between theoretical and applied structural macrodynamic model building. We hope that the book will be a useful reference for all researchers, academic teachers and practitioners of macroeconomic and macro econometric model building who are interested in economic dynamics, independently of whether they use equilibrium or disequilibrium methods in their own research. We base this hope on the fact that our approach contains a number of unique features. The emphasis on the identification and analysis of the basic feedback mechanisms at work in modern macro economies. A detailed study of the partial as well as integrated dynamic interaction between these feedback mechanisms that consti tute the interdependence of markets and sectors of the modern macro economy. The rela tionship between the macroeconomic framework of our working model and the Walrasian, Non-Walrasian and New-Keynesian reformulations of macroeconomics.
