This proceedings volume contains papers presented at the conference on econometric decision models held at the University of Hagen (= Fern- Universitat), June 19-20, 1981. Included are also two papers by authors from abroad which could not be presented during the conference: one by E.O. Heady et al. from the USA and one by H. and J. Wallenius from Finland. The authors of the 18 papers/extended abstracts included in this volume are econometricians, economists and operations researchers. The papers were contributed by scientists from the following coun- tries: West Germany (10 papers), The United States (3 papers), The Netherlands (2 papers), Finland (1 paper), Switzerland (1 paper) and Yugoslavia (1 paper). Although all but one authors come from universities, the audience of the conference also came from economic agencies at the federal and state level. This composition of the audience made for a fruitful exchange of ideas on the possibility and necessity of improving econo- metric decision models so that these models may play a greater role in practical policy decision making. Some further remarks on this topic can be found in the introductory paper of this volume. For providing financial support of the conference, I wish to thank the University of Hagen (and the taxpayer in the State of Northrhine-West- falia), the 'Gesellschaft der Freunde der FernUniversitat" (= Society of the Friends of the University of Hagen), and several banks.: Commerzbank Hagen, Commerzbank Hohenlimburg, Sparkasse Hagen, Volks- bank Hagen.
