Vortrag in Linz im KunstRaum Goethestrasse am 25.09.2002 im Rahmen der Reihe ESTABLISH CULTURAL WORKER - Ist die KulturArbeit (oder) Kunst?: Zuerst möchte ich kurz zu dem Moriana Projekt etwas sagen. Es wurde in 7 Städten durchgeführt, und war ein europäisches Forschungsprojekt von einem italienischen Forschungsinstitut. Es ging um die Situation von Kleinstselbstständigen, FreiberuflerInnen etc. Dies mit einem erneuerten Ansatz dessen, was früher einmal Arbeitermituntersuchung hiess, nämlich militante Untersuchung. Das heisst, die Leute die in den Verhältnissen stecken, analysieren selbst ihre Arbeitssituation, versuchen selbst ihre Bedürfnisse zu beschreiben, versuchen selbst diesen Arbeitsprozess zu beschreiben, und werden, durch einen Intervention des/der ForscherIn, versucht in eine bestimmte Richtung zu drängen. Nämlich in die Richtung, für ihre Interessen zumindest zu einer Selbstformulierung zu kommen, wenn nicht gar zu einer Selbstorganisierung. Letzteres hat bei dem Projekt nicht geklappt, oder nur zu ganz kleinen Teilen. ...
Das vorliegende Arbeitspapier analysiert die sich in Westmittelfranken konzentrierende Kunststoff verarbeitende Industrie. Im Mittelpunkt der Analyse stehen die Wertschöpfungsprozesse der Unternehmen und damit verbunden unterschiedliche Interaktionsformen und Vertragsbeziehungen innerhalb der Branche. Die Arbeit diskutiert, ob es sich bei der regionalen Konzentration der Branche um ein sogenanntes Cluster handelt, aus dem Unternehmen Synergien bei der Wertschöpfung und unternehmerische Wettbewerbsvorteile gewinnen können. Die Analyse ist Teil eines Forschungsprojektes zum Thema „Innovationsfinanzierung im Mittelstand“ am Institut für Humangeographie (Abteilung Wirtschaftsgeographie) der Johann Wolfgang Goethe-Universität Frankfurt.
Ernst Bloch pointed out in a particularly emphatic way that the concept of human dignity featured centrally in historical struggles against different forms of unjustified rule, i.e. domination – to which one must add that it continues to do so to the present day. The “upright gait,” putting an end to humiliation and insult: this is the most powerful demand, in both political and rhetorical terms, that a “human rights-based” claim expresses. It marks the emergence of a radical, context-transcending reference point immanent to social conflicts which raises fundamental questions concerning the customary opposition between immanent and transcendent criticism. For within the idiom of demanding respect for human dignity, a right is invoked “here and now,” in a particular, context-specific form, which at its core is owed to every human being as a person. Thus Bloch is in one respect correct when he asserts that human rights are not a natural “birthright” but must be achieved through struggle; but in another respect this struggle can develop its social power only if it has a firm and in a certain sense “absolute” normative anchor. Properly understood, it becomes apparent that these social conflicts always affect “two worlds”: the social reality, on the one hand, which is criticized in part or radically in the light of an ideal normative dimension, on the other. For those who engage in this criticism there is no doubt that the normative dimension is no less real than the reality to which they refuse to resign themselves. Those who critically transcend reality always also live elsewhere.
The overvaluation hypothesis (Miller 1977) predicts that a) stocks are overvalued in the presence of short selling restrictions and that b) the overvaluation increases in the degree of divergence of opinion. We design an experiment that allows us to test these predictions in the laboratory. The results indicate that prices are higher with short selling constraints, but the overvaluation does not increase in the degree of divergence of opinion. We further find that trading volume is lower and bid-ask spreads are higher when short sale restrictions are imposed.

Regulations in the pre-Sarbanes–Oxley era allowed corporate insiders considerable flexibility in strategically timing their trades and SEC filings, for example, by executing several trades and reporting them jointly after the last trade. We document that even these lax reporting requirements were frequently violated and that the strategic timing of trades and reports was common. Event study abnormal re-turns are larger after reports of strategic insider trades than after reports of otherwise similar nonstrategic trades. Our results also imply that delayed reporting is detrimental to market efficiency and lend strong support to the more stringent trade reporting requirements established by the Sarbanes–Oxley Act.

This paper studies the market quality of an internalization system which is designed as part of an open limit order book (the Xetra system operated by Deutsche Börse AG). The internalization sys-tem (Xetra BEST) guarantees a price improvement over the inside spread in the Xetra order book. We develop a structural model of this unique dual market environment and show that, while adverse selection costs of internalized trades are significantly lower than those of regular order book trades, the realized spreads (the revenue earned by the suppliers of liquidity) is significantly larger. The cost savings of the internalizer are larger than the mandatory price improvement. This suggests that internalization can be profitable both for the customer and the internalizer.

This paper reconsiders the effect of investor sentiment on stock prices. Using survey-based sentiment indicators from Germany and the US we confirm previous findings of predictability at intermediate time horizons. The main contribution of our paper is that we also analyze the immediate price reaction to the publication of sentiment indicators. We find that the sign of the immediate price reaction is the same as that of the predictability at intermediate time horizons. This is consistent with sentiment being related to mispricing but is inconsistent with the alternative explanation that sentiment indicators provide information about future expected returns.

This paper examines to what extent the build-up of "global imbalances" since the mid-1990s can be explained in a purely real open-economy DSGE model in which agents’ perceptions of long-run growth are based on filtering observed changes in productivity. We show that long-run growth estimates based on filtering U.S. productivity data comove strongly with long-horizon survey expectations. By simulating the model in which agents filter data on U.S. productivity growth, we closely match the U.S. current account evolution. Moreover, with household preferences that control the wealth effect on labor supply, we can generate output movements in line with the data. JEL Classification: E13, E32, D83, O40
In this lecture, the context and conditions of becoming a teacher from the time of being selected into the programme, through the process of training and being retained to teach are discussed within the framework of Teacher Education in Nigeria. First, the concepts and the history of teacher education are examined. Then, some critical issues as well as my personal research efforts on teacher education are discussed. Finally, recommendations for meeting the challenges of Teacher Education in Nigeria are made.
