This book analyses the situation in the new economy from a scientific point of view. The success and the failure of enterprises of the new economy create a challenge to management and to the theory of the firm. This volume answers the question in which way well-established concepts of the theory of the firm should be modified or new approaches should be created in order to run enterprises of the new economy successfully. The contributions include various fields of the theory of the firm and are therefore divided into the six essential disciplines of economic research which are production and procurement, finance, marketing, accounting, human resource management and economic organization and corporate governance.

In studying General Equilibrium Theory the student must master first the theory and then apply it to solve problems. At the graduate level there is no book devoted exclusively to teaching problem solving. This book teaches for the first time the basic methods of proof and problem solving in General Equilibrium Theory. The problems cover the entire spectrum of difficulty; some are routine, some require a good grasp of the material involved, and some are exceptionally challenging. The book presents complete solutions to two hundred problems. In searching for the basic required techniques, the student will find a wealth of new material incorporated into the solutions. The student is challenged to produce solutions which are different from the ones presented in the book.

This volume contains the results of the International Conference on "Man­ aging Enterprises ofthe New Economy by Modem Concepts ofthe Theory ofthe Firm", which took place in Hagen from 12-14 December 2002. The conference was organised jointly by the FernUniversität in Hagen and the Erich-Gutenberg-Arbeitsgemeinschaft in Cologne. The Deutsche For­ schungsgemeinschaft, the FernUniversität and the Märkische Bank in Hagen provided generous financial support for the conference, and in fact enabled its implementation and the publication of this record of the pro­ ceedings. We would like to express our gratitude to the sponsors for their support. The aim of the conference was the exchange of academic experience with regard to new approaches to, and extensions of, the theory of the firm that can be used to solve the problems of New Economy companies. The starting point was the practical experience that the owners and managers of New Economy companies paid too little attention to functional company controls in the general euphoria regarding future economic trends and that because of this the enterprises got into difficulties or were faced with threats to their survival. These control deficits were detected equally in the areas of sales, production, personnel planning, organisation and finance and in the arrangement of management and control structures. Deficiencies in company evaluations and accounting led to investors experiencing se­ vere disappointment on the loss of their invested capital.
