Economics and the treatment of AIDS: a preliminary assessment

This paper applied cost-effectiveness analysis to the use of drug therapy in the treatment of AIDS. The empirical approach adopted overcame the facts that the samples of patients had varying clinical prognoses, had variable entry dates into the samples and, because AIDS is a terminal disease, had variable exit dates. Holding these variables constant, administration of the drug AZT proved to be a less costly alternative than other existing palliatives for AIDS. The sub-sample of patients treated with AZT had lower hospitalization costs, lower caring costs and sufferers had an increased ability to continue to participate for longer as economically active members of society.     

Debt Relief as a Last Resort for the Lender of Last Resort?

The coronavirus crisis has led to a sharp increase in the debt-to-GDP ratios of the euro area member states. Without external support, access to the capital market could be seriously threatened in the medium term for Italy, but also for other member states. While the Pandemic Emergency Purchase Programme, which is designed as a monetary policy instrument, is regarded by some as a violation of the prohibition of monetary financing, the Next Generation EU recovery fund is likely to direct the fundamental structures of the European Union towards a fiscal union with considerable redistribution elements. This article analyses an alternative strategy, namely debt relief by the European System of Central Banks through an EU debt agency. Such a scheme would be possible without amending the EU treaties and would avoid negative equity at the central banks. The question is under what circumstances would this approach be suitable and proportionate?

     

The Determinants of Plant Exit: the Evolution of the U.S. Refining Industry

This paper analyzes the exit and expansion of U.S. petroleum refineries using plant-level data from 1947 to 2013. We find that small refineries and refineries owned by a multi-plant firm are more likely to close. If a multi-plant firm closes a refinery, it closes a smaller one. Unlike previous research, we find no clear relationship between a firm’s share of national refining capacity and the probability of refinery exit. We also find that refineries close when the industry as a whole has low capacity utilization. In total, firms close small, likely inefficient, refineries when refinery utilization is low.     

Schuldenerleichterungen für Griechenland — ein Überblick

The article provides an overview of debt waivers by private and public debt holders during the Greek financial crisis and the three assistance programmes. Greece’s advantages add up to around 280 to 298 billion euros. The burden, in the form of reduced annual payments, is carried by the debt-holding countries and amounts to about 206 to 224 billion euros, the private sector’s share being roughly 70 %. Nevertheless, liability shifted from the private sector to rescue funds. Therefore, the aforementioned additional debt relief will primarily strain the countries that pay for the bail out and the ECB.     

The Evolution and Challenges of the Concept of Organizational Virtuousness in Positive Organizational Scholarship

This study considers the potential for influencing business students to become ethical managers by directing their undergraduate learning environment. In particular, the relationship between business students’ academic cheating, as a predictor of workplace ethical behavior, and their approaches to learning is explored. The three approaches to learning identified from the students’ approaches to learning literature are deep approach, represented by an intrinsic interest in and a desire to understand the subject, surface approach, characterized by rote learning and memorization without understanding, and strategic approach, associated with competitive students whose motivation is the achievement of good grades by adopting either a surface or deep approach. Consistent with the hypothesized theoretical model, structural equation modeling revealed that the surface approach is associated with higher levels of cheating, while the deep approach is related to lower levels. The strategic approach was also associated with less cheating and had a statistically stronger influence than the deep approach. Further, a significantly positive relationship reported between deep and strategic approaches suggests that cheating is reduced when deep and strategic approaches are paired. These findings suggest that future managers and business executives can be influenced to behave more ethically in the workplace by directing their learning approaches. It is hoped that the evidence presented may encourage those involved in the design of business programs to implement educational strategies which optimize students’ approaches to learning towards deep and strategic characteristics, thereby equipping tomorrow’s managers and business executives with skills to recognize and respond appropriately to workplace ethical dilemmas.     

A unified approach to systemic risk measures via acceptance sets

We specify a general methodological framework for systemic risk measures via multidimensional acceptance sets and aggregation functions. Existing systemic risk measures can usually be interpreted as the minimal amount of cash needed to secure the system after aggregating individual risks. In contrast, our approach also includes systemic risk measures that can be interpreted as the minimal amount of cash that secures the aggregated system by allocating capital to the single institutions before aggregating the individual risks. An important feature of our approach is the possibility of allocating cash according to the future state of the system (scenario‐dependent allocation). We also provide conditions that ensure monotonicity, convexity, or quasi‐convexity of our systemic risk measures.     

Müssen wir uns vor Staatsfonds schützen?

Staatliche Verm?gensfonds suchen derzeit auf den internationalen Finanzm?rkten nach Anlagem?glichkeiten für mehr als 3 Billionen US-Dollar, und die Fondsvolumina wachsen rasant. Wie wirkt sich das Engagement von Staatsfonds auf die inl?ndische Wirtschaft in potentiellen Anlagel?ndern aus und wie sollte darauf reagiert werden? Sind die Bestrebungen der Bundesregierung, Staatsfonds durch neue gesetzliche Regeln besser kontrollieren zu k?nnen, ?konomisch gerechtfertigt? Gibt es konkrete Hinweise darauf, welche Anlagestrategien die Staatsfonds tats?chlich verfolgen? Prof. Dr. Henning Klodt, 56, leitet das Zentrum Wirtschaftspolitik am Institut für Weltwirtschaft in Kiel. * Für vielf?ltige Anregungen und Hinweise dankt der Autor den Teilnehmern der Politikwerkstatt „Motive und Anlagestrategien von Staatsfonds“, die am 24. Januar 2008 gemeinsam vom Bundesministerium der Finanzen und dem Institut für Weltwirtschaft veranstaltet wurde.
