Buchbesprechungen

Zusammenfassungen  Im Fach Kommunikations- und Medienwissenschaft liegen bislang kaum empirische Daten zur Situation des promovierten wissenschaftlichen Nachwuchses vor. Diese Studie gibt Aufschluss über Besch?ftigungssituation, Berufszufriedenheit, Betreuung sowie Karrierevorstellungen und -strategien der Post-Doktorandinnen und-Doktoranden des Faches. Die Ergebnisse einer Befragung im deutschsprachigen Raum zeigen, dass die Postdocs mit ihrer beruflichen Situation, vor allem mit den Arbeitsinhalten und der Flexibilit?t der Arbeitszeiten zufrieden sind und eine akademische Karriere anstreben. Die Konkurrenz und die Hürden auf dem Karriereweg werden allerdings als gro? wahrgenommen. Zudem scheinen die als vielversprechend eingesch?tzten Karrierestrategien wie das Publizieren in internationalen Fachzeitschriften nur schwer umsetzbar zu sein. Einzig jene Postdocs, die von ihrer/m vorgesetzten Professor/in beim Publizieren und beim Aufbau eines Netzwerks unterstützt und betreut werden, schaffen es, viel zu publizieren und international in Erscheinung zu treten. Hingegen sind zwei andere Gruppen weniger erfolgreich in der Umsetzung der eigenen Ziele bzw. verfolgen mit der Habilitation eher traditionelle Karrierestrategien.

Are many paths leading to Rome? Professional situation and career strategies of post-doc scholars in communication and media studies

There are hardly any data on the situation of post-doc scholars in the field of communication and media studies. This study describes the employment, job satisfaction, mentoring, and career concepts and strategies of post-docs in the field. A survey among post-docs in the German-speaking countries shows that they are satisfied with their job situation, especially the kind of work they have to do and the flexibility of their working hours. They also aspire to a career in academia. Competition and obstacles on the career path are, however, perceived as considerable. Some strategies such as publishing in international journals are seen as promising, but hard to attain. Only those post-docs who are supported by the professor they work for succeed in publishing much and getting to be known internationally. Other groups are less successful in reaching their goals or pursue the traditional career path of habilitation.

The Productivity of Government Spending in Asia: 1983–2000

Leightner [The Changing Effectiveness of Key Policy Tools in Thailand. Institute of Southeast Asian Studies for East Asian Development Network, EAON Working Paper 19(2002)x0219-6417] develops a new analytical technique, named Reiterative Truncated Projected Least Squares (RTPLS), which produces 1/2 the error of OLS when omitted variables interact with the included independent variable. In this paper, RTPLS is applied to annual panel data on government spending and GDP from 1983 to 2000 for 23 developing Asian and Pacific countries. RTPLS produces estimates for the government spending multiplier for these countries and shows how omitted variables have affected these multipliers across countries and over time.JEL Classification: C13, E62, O23     

On consistency of redescending M-kernel smoothers

M-estimators and M-kernel estimators with a redescending ψ-function are not in general consistent. This is often handled by means of coupling the estimator to a consistent one. Coupling the estimator to the (inconsistent) starting point improves the jump preserving properties. However, the consistency depends heavily on the shape of the density of the residuals. This paper shows inconsistency under convenient conditions as well as consistency – even at jump points – under somewhat stronger conditions.

Efficiency of Nonpoint Source Pollution Instruments: An Experimental Study

In nonpoint source pollution problems, the regulator does not observe each polluters individual emission, which prevents him from using the conventional policy instruments. Therefore, new instruments have been designed to regulate this type of pollution. In an experiment, we compare the efficiency of some of these instruments: an input-based tax, an ambient tax/subsidy, an ambient tax, and a group fine. We assume that polluters themselves are affected by environmental damages. A control session without any regulation is also carried out in order to study the status quo situation. Our experimental data show that the input tax and the ambient tax are very efficient and reliable, and the group fine is fairly efficient and reliable. These instruments improve social welfare with respect to the status quo. On the contrary, the ambient tax/subsidy decreases social welfare with respect to the status quo, and its effect is very unreliable.     

Efficiency Measurement in Network Industries: Application to the Swiss Railway Companies

The persistence of increasingly high government subsidies in Switzerland’s railroads has led the federal and cantonal authorities to discussing the possibility of high-powered incentive contracts such as those based on cost efficiency benchmarking. Railways are however, characterized by a high degree of unobserved heterogeneity that could bias the efficiency estimates. This paper examines the performance of several panel data models to measure cost efficiency in network industries. The unobserved firm-specific effects and the resulting biases are studied through a comparative study of several stochastic frontier models, applied to a panel of 50 railway companies operating over a 13-year period.* The authors wish to thank Michael Crew and two anonymous referees for their helpful suggestions.

Planung und Unternehmenserfolg: Stylized Facts aus der empirischen Controllingforschung im deutschsprachigen Raum von 1990–2007

Zusammenfassung Der vorliegende Beitrag untersucht, inwieweit die empirische Controllingforschung im deutschsprachigen Raum von 1990 bis 2007 belastbare Aussagen (“Stylized Facts”) zum Zusammenhang zwischen der Gestaltung der Planung als bedeutsamem Teil der Controllerarbeit und dem Controlling- bzw. Unternehmenserfolg erarbeitet hat. Insgesamt werden fünfzehn Studien analysiert, aus denen Stylized Facts zu Planungsintensit?t, Planungsrationalit?t, Planungsoffenheit, Planungsintegration und Planungsdauer sowie zu Opportunismus und Kompetenzgef?lle als soziale Gestaltungsfaktoren der Planung hergeleitet werden. Zum einen zeigen die Ergebnisse den Beitrag der empirischen Controllingforschung zum Verst?ndnis der Planung als Führungsteilfunktion. Zum anderen k?nnen verschiedenste Aussagen zur Gestaltung der Planung in handlungsleitender Form an die Unternehmenspraxis zurückgespielt werden.      

External shocks, U.S. monetary policy and macroeconomic fluctuations in emerging markets

Estimated structural VARs show that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly. The price level and real output in a typical emerging market respond to U.S. monetary policy shocks by more than the price level and real output in the U.S. itself. These findings are consistent with the idea that “when the U.S. sneezes, emerging markets catch a cold.” At the same time, U.S. monetary policy shocks are not important for emerging markets relative to other kinds of external shocks.

Asymmetric Risk Measures and Real Estate Returns

Rational investors distinguish between extremely high and extremely low returns. The measures of investment risk should reflect such asymmetric risk perception. This study presents six asymmetric risk metrics and empirically tests their abilities in explaining the cross-sectional variations of real estate returns. It finds strong evidence that systematic downside risk is associated with a risk premium, and skewness provides significant explanatory power to the variation of cross-sectional property returns. On the other hand, co-skewness does not explain real estate returns well and is not a good systematic risk measure.
