The econometric consequences of nonstationary data have wide ranging im plications for empirical research in economics. Specifically, these issues have implications for the study of empirical relations such as a money demand func tion that links macroeconomic aggregates: real money balances, real income and a nominal interest rate. Traditional monetary theory predicts that these nonsta tionary series form a cointegrating relation and accordingly, that the dynamics of a vector process comprised of these variables generates distinct patterns. Re cent econometric developments designed to cope with nonstationarities have changed the course of empirical research in the area, but many fundamental challenges, for example the issue of identification, remain. This book represents the efforts undertaken by the authors in recent years in an effort to determine the consequences that nonstationarity has for the study of aggregate money demand relations. We have brought together an empirical methodology that we find useful in conducting empirical research. Some of the work was undertaken during the authors' sabbatical periods and we wish to acknowledge the generous support of Arizona State University and Michigan State University respectively. Professor Hoffman wishes to acknowledge the support of the Fulbright-Hays Foundation that supported sabbattical research in Europe and separate support of the Council of 100 Summer Research Program at Arizona State University."

Karl Brunner Monetary affairs have preoccupied observers over the ages. In the middle of the 14th century, the chaos in the French currency system after many rounds of currency debasement attracted comments expressing helpless confusion. Goethe's Mephistopheles convinced the imperial court to inflate with paper money "for the benefit of the public" and to satisfy all the demands on the government's largesse. Our century is no exception. The massive technological improvement in creating money has contributed to hyperinflationary experiences never before recorded in history. These events occurred, however, in the political disarray following major wars. More important are the persistent pe ace time failures of our monetary institutions. A massive worldwide deflation, centered in the United States and Germany, imposed a tragic social and political fate on Western societies. Similarly, the sequence of a worldwide inflation followed by deflation observed over the past 15 years has fostered disruptive economic and political conditions. The monetary disarray experienced throughout history was crucially influenced by the prevailing monetary arrangements. These arrangements determine the level and movement of the nation's money stock over time. Under the circumstances, the political issue confronting us bears on the useful choice of monetary arrangements. This choice should involve institutions that prohibit both massive deflation and persistent inflation.

Die j{hrlichen H{mophilie-Symposien befassen sich mit neuen Erkenntnissen aus der Grundlagenforschung und Klinik der H{- mophilie, verwandter angeborener und erworbener Blutungs- krankheiten und thrombophiler Diathesen. Diese Veranstaltun- gen verfolgen das Ziel, unter Mitwirkung kompetenter Modera- toren und Referenten aller involvierten Fachdisziplinen, [rzten und Wissenschaftler aus dem zentraleurop{ischen Raum aktuelle Erkenntnisse und Erfahrungen zu vermitteln und eine stetige Verbesserung der Krankenversorgung zu bewirken. Die Hauptthemen des vorliegenden Bandes sind auf therapiebe- dingte Gef{hrdungendurch Virusinfektionen und nicht-infek- ti|se Nebenwirkungen gerinnungsaktiver Plasmapr{parate ge- richtet. Im Vordergrund stehen dabei H{ufigkeit, Verlauf, Verh}tung und Therapie der HIV-Infektion, H{ufigkeit und Verh}tung der Hepatitis B- und C-Infektion sowie Behand- lungswege der Hemmk|rperh{mophilie. In weiteren Hauptthemen werden angeborene bzw. heredit{re thrombophile Diathesen, insbesondere Protein C- und Antithrombin III-Mangelzust{nde sowie neue, vor allem molekularbiologische Fortschritte in der h{mostaseologischen Diagnostik verhandelt. Den Abschlu~ bildet eine Serie freier Vortr{ge }ber spezielle klinische Probleme bei angeborenenund erworbenen H{mostasest|rungen.

Die Hamatologie hat im vergangenen Jahrzehnt einen erheblichen Zu- wachs an Wissen und Erkenntnissen erfahren. Dies gilt sowohl fur die Physiologie und Pathologie der Zellsysteme auf molekularer Basis, als auch fur die Identifizierung und Beschreibung klinischer Syndrome und definierter Krankheitsbilder. Die Erforschung der ZeIIkinetik hat wesent- lich zum Verstandnis der regulativen Vorgange beigetragen. Am aufregendsten ist zweifellos die Entwicklung im Bereich der Lympho- zyten und Granulozyten mit der Aufdeckung von bisher nicht gekannten Funktionen und Funktionsdefekten. Der Erythrozyt hat weitere Geheim- nisse preisgegeben, vor allem uber die Membran, die Enzyme und das Hamoglobin, sowie uber seine rheologischen Eigenschaften. Die Hamosta- seologie hat die Methoden der Diagnostik erheblich verbessert und auf einigen Gebieten die therapeutischen Moeglichkeiten entscheidend ausge- baut. Die Mehrzahl der Autoren dieses Buches sind Padiater und die Belange des Kindes werden entsprechend berucksichtigt. Die padiatrische Hamatologie hat als Spezialdisziplin ihren festen und berechtigten Platz innerhalb der Padiatrie und der Hamatologie. Von der Hamatologie des Erwachsenen unterscheidet sie sich in vielen Punkten. Das gilt sowohl fur die Normwerte hamatologiseher Daten, als auch fur das Spektrum der Erkrankungen des hamatopoetischen Systems. Insbesondere bietet das Neugeborene viele hamatologische Eigentumlichkeiten, die hier in einem eigenen Kapitel zusammenfassend dargestellt werden. Auch hinsichtlich der Durchfuhrung und Zumutbarkeit diagnostischer und therapeutischer Massnahmen ergeben sich Unterschiede zwischen Kind und Erwachsenem.
