Einnahmen- und ausgabenseitige Multiplikatoren der deutschen Volkswirtschaft

Theoretically based on the Haavelmo theorem, this study analyses the economic effects that increasing public expenditure or reducing public income have on the gross domestic product of Germany, with the help of two medium-sized macro-econometric models, the RWI business cycle model and the Econometric Model of the German Economy. The major finding is that most of the public revenue multipliers are considerably lower than most of the public spending multipliers. However, both the dimension and the time course of the effects are a function of the specific kind of politico-economic measures taken by the government.     

Hygiene bei verzögerter Wundheilung

Ultraschall-assistierte Wundbehandlung - Trotz der Therapie der Ursache einer Wunde und phasengerechter Wundbehandlung heilen Wunden nicht immer ad?quat. Dann besteht die M?glichkeit, alternative Therapietechniken, wie die Ultraschall-assistierte Wundbehandlung, anzuwenden. Worauf muss dabei geachtet werden?     

Tracheotomie bei Kindern

Indikationen, Durchführung, Komplikationen - Dank des medizinischen Fortschritts überleben immer mehr p?diatrische Patienten die intensivmedizinische Behandlung. Ein Teil von ihnen bleibt jedoch danach chronisch krank und bedarf medizinischer Ma?nahmen. So kann anhaltende respiratorische Insuffizienz die Anlage eines Tracheostomas erforderlich machen. Etwa 3% aller intensivpflichtigen Kinder erhalten eine Tracheotomie.     

Resurrecting Lochner: A Defense of Unprincipled Judicial Activism

Lochner v. New York, 198 U.S. 45 (1905), stands as one of theSupreme Court's most reviled decisions. We challenge the criticalconsensus against Lochner and provide a defense, albeit a contingentdefense, of "unprincipled" judicial activism. To do so, we developa game-theoretic model of judicial–legislative interaction.We use the model to compare outcomes generated in a system oflegislative supremacy to outcomes generated in a system in whichjudicial review is provided by a legally unprincipled, activistjudiciary. We show that judicial review, even when providedby an activist, politicized judiciary, can promote importantconstitutional values and improve legislative quality relativeto a deferential judiciary. In doing so, we identify an important"passive" component to the effect that judicial review has onlegislatures and on legislation. Finally, we demonstrate thatthe addition of other institutions and constraints on judicialbehavior amplify the beneficial effects that judicial reviewprovides to the legislative process.     

Corporate foresight: Its three roles in enhancing the innovation capacity of a firm

In the last three decades much knowledge has been produced on how best to conduct foresight exercises, but little is known on how foresight should be integrated with the innovation effort of a company. Drawing on empirical evidence from 19 case studies and 107 interviews, we identify three roles that corporate foresight should play to maximize the innovation capacity of a firm: (1) the strategist role, which explores new business fields; (2) the initiator role, which increases the number of innovation concepts and ideas; and (3) the opponent role, which challenges innovation projects to increase the quality of their output.

Forecasting U.S. car sales and car registrations in Japan: Rationality, accuracy and herding

We analyze forecasts of car sales in the U.S. and forecasts of car registrations in Japan. We document a substantial heterogeneity of forecasts, and we show that, based on traditional criteria, forecasts are neither rational nor unbiased. We also report that forecasters anti-herd, that is, forecasters seem to intentionally scatter their forecasts around a consensus forecast. We further show that cross-sectional heterogeneity of forecasts with regard to anti-herding transmits onto cross-sectional heterogeneity of forecast accuracy. Specifically, we document that forecasters who herd provide more accurate forecasts than their colleagues who anti-herd.     

Das journalistische Feld in Deutschland

By using Bourdieus’ thinking tools field, habitus and capital, this article first develops a concept of the journalistic field, in which economic capital and journalistic capital decide on (collective and individual) agents’ latitude and in which their autonomy could be influenced by economic logic, the discussion on journalistic norms and the logic of other social fields. Subsequently, this concept is implemented in a qualitative study. For that purpose 501 guideline interviews with journalists were conducted; they were asked about their career, their working conditions and their role perception. The findings show that in Germany nowadays the journalistic field is dominated by information professionals, who know their craft and who made the needs of the audience the benchmark of their work. Different from what literature suggests, it makes little sense to differentiate between a “commercial” and an “intellectual” pole. Exclusive news (which is what the field is all about) can only be produced where enough capital is available. At the centre of power, to which news magazines, national daily newspapers and public broadcasting stations belong, one can most easily withdraw from the economic logic and the influence that emanates from the audience and the advertising clients.
