The main item on the agenda was (after securing and formally announcing the site of the 5th DG Symposium as Geneve, July 15-16, 1992) to decide on the site of the 6th DG Symposium of the Society, for 1994. At the meeting the pros and cons of four proposals (proposals from Japan, Soviet Union, Netherlands and USA) were discussed at great length, and the unanimous decision was to hold it in Colorado, USA, and to have Bolek Tolwinski shoulder the organization of the symposium. The exact location of the symposium will be announced later on. XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Contributed by Marilu Petit July 12 ANNOUNCING A NEW BOOK Control Theory and Dynamic Games in Economic Policy Analysis by Maria Luisa Petit -From the inside folder- This book deals with the stabilization and control of an economic system in a dynamic setting. Unlike other studies in the area which consider only the case of centralized policy-making, professor Petit examines both the situation in which policy decisions are taken by a single policy-maker and the case of group policy-making. The wide ranging economic implications of the use of these methods are thoroughly discussed. The tools of optimal control and differential game theory, and their advantages and drawbacks, are examined, along with methodological implications of introducing expectations into the policy problem. This lucid and comprehensive study of control theory and dynamic games will be of great use both to economists interested in learning mathematical methods and to mathematicians interested in their economic applications. It shows the important economic insights that can be obtained by using the appropriate mathematical methodology and is particularly valuable for bridging the gap between highly specialized books and traditional treatments of static economic policy.

Among different time-domain approaches to this class of worst-case design problems, the one that uses the framework of dynamic (differential) game theory stands out as the most natural. This is so because the original H-infinity optimal control problem (in its equivalent time-domain formulation) is in fact a minimax optimization problem, and hence a zero-sum game, where the controller can be viewed as the minimizing player and the disturbance as the maximizing player. Using this framework, the authors develop in this book a complete theory that encompasses continuous-time as well as disorete-time systems, finite as well as infinite horizons, and several different measurement schemes, including closed-loop perfect state, delayed perfect state, sampled state, closed-loop imperfect state, delayed imperfect state and sampled imperfect state information patterns. The authors believe that the theory is now at a stage where it can easily be incorporated into a second-level graduate course in a control curriculum, that would follow a basic course in linear control theory covering LQ and LQG designs. The framework adopted in this book indeed makes such an ambitious plan possible. For the most part, the only prerequisite is a basic knowledge of linear control theory. No background in differential games, or game theory in general, is required, as the requisite concepts and results have been developed in the book at the appropriate level. Furthermore, the book is written in such a way that makes it possible to follow the theory for the continuous- and discrete-time systems independently (and also in parallel). The general framework adopted, and the methodologies developed, also open new avenues of research for the reader, to extend these results to more general classes of systems, such as nonlinear plants and/or distributed parameter systems.

Thoma, A. Wyner, Springer-Verlag ISBN 3-540-53787-2 Softcover DM 79,- -From the Springer-Verlag’s announcement- The present collection of articles shows that there is a strong new boom of interest in the area of dynamic games. The papers included in this volume give a relatively wide coverage of the new problems in the area. Thus it is likely to serve as a useful source of up to date problem formulations and references for established researchers as well as for new researchers who are entering this field. In these proceedings the papers have been grouped into four sections dealing with: - zero-sum differential games of pursuit-evasion type and their applications to aerospace problems; - search and discrete games; - robust controller design; - numerical and hierarchical methods. Dynamic Games in Economic Analysis Edited by R.P. Hamalainen and H.K. Ehtamo Proceedings of the 4th International Symposium on Differential Games and Applications, August 9-10, 1990, Helsinki University of Technology, Finland Lecture Notes in Control and Information Sciences, Vol. 157, April 1991 Eds.: M. Thoma, A. Wyner, Springer-Verlag ISBN 3-540-53785-6 Softcover DM 79,- -From the Springer-Verlag’s announcement- The theory of dynamic games is becoming an increasingly important tool in economic analysis. Many resource and environmental problems are naturally formulated as dynamic incentives, coordination and hierarchical organizations. Also energy economics is an area where dynamic solutions are used in real life problems. This volume gives a relatively wide coverage of examples of all these new developments. In these proceedings the papers have been grouped into four sections dealing with: - problems in management science and economics; - incentives and coordination; - resource management and environmental problems; - hierarchical gtame models and computational aspects.

Kort Optimal Dynamic Taxation: A Game Theoretic Approach In the last decade, there has been a substantial development in the applications of dynamic models, which are used to describe the economic behavior of firms. In some of these studies the impact of different kinds of taxations are investigated. However, in these models the government instruments are given exogenously. By doing this the Lucas’ eritique is neglected. The aim of this thesis is to extend this framework by modelling the government endogenously. In different game theoretic equilibria the government chooses the level of corporate taxation. In the feedback Stackelberg equilibrium higher taxes will be asked and there is less investment and capital than in the open-loop equilibrium, where both players are better off. Starting from a simple model, we extend it with other policy instruments and with different objective functions for the government, and with a more advanced model for the firm. Finally, it is incorporated in a general equilibrium framework where also consumer behaviour is modelled. Attention is paid to the derivation of feedback Stackelberg equilibria. In the last chapter the issue of optimal taxes and debts are analysed. It is shown that if government's spending is productive instead of exhaustive and a credibility constraint is imposed, there is an additional role for debt policy.
