This is a study of volume and the nonlinear dynamics of stock returns. It examines efficient stock markets, the informational role of volume, volume and the volatility of stock returns, nonlinear analysis of return and volume and testing the structural model.

This thesis was stimulated throughout the time of my participation in a research project on Dynamic Macroeconomics, supported by the German Research Foundation (DFG). The starting point was the central question of how to integrate price setting firms in a dynamic disequilibrium model. Almost all recent literature on imperfect competition in macroeconomics applies the objective demand approach by assuming that firms know the true demand curve they are faced with. While this approach can be ap plied in temporary monetary equilibrium models, it proves inadequate for formulating price adjustment...

This book presents recent developments in the field of ill-posed variational problems and variational inequalities, covering a large range of theoretical, numerical and practical aspects. The main topics are: - Regularization techniques for equilibrium and fixed point problems, variational inequalities and complementary problems, - Links between approximation, penalization and regularization, - Bundle methods, nonsmooth optimization and regularization, - Error Bounds for regularized optimization problems.

This book uses the result of a behaviorial experimental to form a behavioral principal-agent model that gives valuable insight into the interaction of trust, trustworthiness and information sharing strategy, and how this impacts the supply chain performance.

K. Bauknecht, Zurich w. Nef, Bern Als Simulation im allgemeinen Sinn wird die untersuchung des Verhaltens eines Systems mit Hilfe eines Ersatzsystems bezeichnet. Ein bekanntes Beispiel ist etwa durch die Flugzeugsimulatoren fur die Ausbildung von Piloten gegeben. Der Grund fur die Durchfuhrung der Simulation anstelle der direkten Betrachtung des eigentlich interessierenden Systems kann verschiedenartig sein. Meistens wi d die Durchfuhrung der notwendigen Versuche aus praktischen GrUnden nicht moglich sein (etwa beim Verkehrssystem einer Gross stadt), oder zu grosse Kosten verursachen...

Das zentrale Interesse heutiger Forschung auf dem Gebiet der mathematischen Programmierung gilt speziellen Fragen der linearen Programmierung so wie allgemeinen Problemen der nichtlinearen Pro grammierung. Unter den speziellen Fragen der linea ren Programmierung ist der mit dem Stichwort De komposition verbundene Komplex aus verschiedenen GrUnden von besonderer Bedeutung und Aktualitat: Einerseits, weil die praktische Anwendung von linearen Programmen haufig zu derart groBen Syste men fUhrt, daB die Speicherkapazitat moderner Re chenanlagen fUr diese Systeme nicht ausreicht, so daB die Idee...

At this point in time, there is no generally accepted methodology for explaining and predicting human behavior given a product choice situation. This is true despite the critical importance of such meth odology to marketing, transportation and urban planning. While the social sciences provide numerous theories to be tested and the mathe matical and statistical procedures exist in general to do so, at this point, no single unified theory has emerged. It is generally accepted that to explain product choice behav ior, products must be described in terms of attributes. Using anyone of a number of...

Digital computers have been used more and more to control different industrial processes during the last decade. As of today, many sy stems are designed to include a process control computer as a vital part. The use of computers has created a need for sophisticated me thods for the operation and supervision of complex industrial proces ses. To summarize the state of the art from the practical as well as from the theoretical point of view, the 4th IFAC/IFIP International Conference on "Digital Computer Applications to Process Control" will be held at Zurich from March 19 to 22, 1974. The first...

This book is intended as a contribution to the theory of contingent claim valuation based on arbitrage considerations. It is concerned with preference-free valuations of contingent claims (such as options written on a stock) in frictionless multiperiod securities markets that do not permit arbitrage profits. Besides the question of pricing it considers the possibility of hedging in securities markets. The research reported in this book was carried out at the Institut fUr Gesellschafts- und Wirtschaftswissenschaften, University of Bonn. While working in this field and preparing this monograph...
