Hamalainen and Harri Ehtamo Systems Analysis Laboratory, Helsinki University of Technology ISDG@HUT.FI xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Dear Dynamic Game Theorist, This is the seventeenth issue of the Society's electronic newsletter. The basic minimum work principle in editing this e-letter is that the READERS send important notes and information about symposia, conferences and workshops of dynamic games, as well as abstracts of Ph.D. theses, papers and books, which they want to be included in the newsletter. The format is described below. We hope that no retyping will be needed so please follow the instructions and sample shown below carefully. The news should be concise to keep the newsletter readable. Requests for more complete information about any news item should be directed to its contributor. We appreciate any comments and suggestions that you may have on this e-letter. Looking forward to receiving your news contributions. Raimo P. Hamalainen and Harri Ehtamo xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Contributed by the Editors February 20 MODEL FOR NEWS SUBMISSIONS Maximum line length is 72 characters. Place the text between two lines of x:ses. The first line should state "Contributed by" and followed by the contributor's name, in brackets and the date. Then there should be a title line and the text. This info block should be sent to ISDG at HUT.FI xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Contributed by Raimo P. H„malainen February 20 World Wide Web (WWW) and ISDG We are currently putting together our WWW-pages here at Systems Analysis Laboratory. We are planning to also have a page for the society with a list of the members and their e-mail addresses. Members who have a WWW-homepage are asked to mail us the address of their own page. Their names will be linked to their personal homepages. Please mail the home page addresses to isdg@hut.fi. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Contributed by Raimo P. Hamalainen February 20 Dear Colleagues, I think it would be a good idea to every now and then have a brief exchange of opinions on important topics in this newsletter of ours. I think that many of us share the opinion that our dynamic game community is relatively isolated from our neighbouring areas. I feel that we could / should do something to improve our visibility. I have some own ideas: 1) I think we could give more emphasis on publicizing applications of differential games. Today dynamic game models are increasingly common, e.g., in the important field of environmental problems. 2) Another thing would be to actively contact OR related researchers, e.g., those interested in group decision and negotiation problems. What do you think ? Perhaps the following excerpts give some further ideas: From the "INTRODUCTION TO THE SPECIAL ISSUE ON DYNAMIC GAME MODELING IN BARGAINING AND ENVIRONMENTAL NEGOTIATIONS," by Raimo P. Hamalainen in the Group Decision and Negotiation, Vol. 4, No. 1, pp. 5-7, 1995, (Kluwer Academic Publ.): In today's world many group negotiations dealing with the management of resources and environmental problems are intrinsically dynamic either through the bargaining process itself or through the evolution of the environmental system in question. Dynamic games are models of interaction among multiple decision makers in settings which develop over time. The literature on dynamic games originates from the traditions of engineering control theory and economic theory. Today dynamic game theorists are active in many different areas of applications ranging from social sciences and economics to engineering, biology, and environmental sciences. The researchers cooperative within the International Society of Dynamic Games... ... Due, in part, to the mathematical complexity of many dynamic game models, the relevance of this methodology has only recently been acknowledged among researchers of goup decision processes. The selected collection of original articles included in this issue aims to give an overview of the current problems of methodological interest - including incentives, cooperation, and bargaining, as well as typical examples of dynamic models of environmental negotiations. Even if dynamic games are good analytic models of dynamic multiagent decision problems, there is clearly still a need to further develop the approach to come up with practically operational group decision support procedures. In this respect, the present special issue brings to the attention of recearchers of group decision making in general the need to pay more attention to the possibilities that dynamic games can offer... ... THE CONTENTS OF THIS SPECIAL issue can be characterized so that the first three articles deal with dynamic game models of environmental and resource management issues, while the last two articles deal with the concepts of intertemporal bargaining problems... ... In their article, "International Negotiations on Carbon Dioxide Reductions," Boleslaw Tolwinski and Wade E. Martin consider the determination of a cooperative solution to a multiplayer dynamic game model which describes global reductions in CO2 emissions... ... The idea that cooperative solutions can be maintained by using suitable incentive mechanisms is addressed in the article, "Credibility of Linear Equilibrium Strategies in a Discrete Time Fishery Management Game," by Harri Ehtamo and Raimo P. Hamalainen... ... Alain Haurie consideres the problem of coordinating a group of rivaling firms when a global environmental emission constraint is imposed on them. He studies coordination through emission taxes and shows that a tax scheme can be designed so that the emission constraint is satisfied asymptotically at an equilibrium steady state... ... The last two articles consider modelling of some possible choice mechanisms behind the cooperative solutions. Harri Ehtamo and Jukka Ruusunen propose an axiomatic approach to intertemporal bargaining, whereas Harlod Houba and Aart de Zeeuw consider a strategic, or sequential approach to intertemporal bargaining... ... It may be interesting to notice that the present collection of articles still addresses the same issues as the pioneering works of the 1994 Nobel Laureates in economics, John Harsanyi, John Nash and Reinhard Selten. These issues of current interest include the concepts of the Nash equilibrium and the Nash bargaining solutions together with Selten's concept of subgame-perfectness... - - - - - - - - - - - - - - - - - - - - Please check the full contents of the issue in your library.

There is a new book out by professor Steven J. Brams that may be of interest to the members of the society. THEORY OF MOVES by Steven J. Brams Professor Brams' book, though based on the classical theory of games, proposes major changes in its rules to render it truly dynamic theory. By postulating that players think ahead not just to the immediate consequences of making moves, but also to the consequences of countermoves to these moves, counter-countermoves, and so on, "Theory of Moves" extends the strategic analysis of conflict into the more distant future. Applied to a series of cases drawn from politics, economics, sociology, fiction, and the Bible, this theory provides not only an explanation of the outcomes of these moves but also shows why they unfolded as they did. Cambridge University Press, 1994 45226-0 (hardcover) 45867-6 (paperback) Professor Brams has also written another game theory related book that came out a few years ago. I put its flyer here as well. NEGOTIATION GAMES: Applying game theory to bargaining and arbitration by Steven J. Brams "Negotiation Games" uses game theory to illuminate the strategic choices of negotiators who have both intersecting and conflicting interests. The reconciliation of differences to reach a settlement may be a primary motivating factor for the bargainers, yet complete honesty in negotiations may result in surrending too much. Thus, exaggeration, posturing, threats, and even outright deception are viewed as rational responses for bargainers in interdependent decision situations (games), where the outcome depends on the choices of all the players. Case studies and theory are brought together in an accessible format for the political scientists and business and law professionals, as well as psychologists, sociologists, economists, and mathematicians.
