Die Wahl zwischen Diversifikation und Spezialisierung ist eine lange und kontrovers diskutierte Frage in der industrieökonomischen Forschung. Inzwischen ist es möglich, anhand von Mikrodaten auf Unternehmensebene die Gestaltung der Produktpalette von Unternehmen zu untersuchen. In dieser...

Das in diesem Artikel beschriebene ökonometrische Prognosemodell stellt einen innovativen Ansatz der Nutzung von amtlichen Firmendaten (Mikrodaten) für die Vorhersage von sektoral bzw. regional differenzierten Fachkräftebedarfen dar. Ziel unseres dynamischen Modells ist eine kurzfristig...

Der Schwerpunkt dieses Beitrags liegt auf den Märkten für Verkehrsinfrastrukturkapazitäten. Mittels geeigneter Preisinstrumente gilt es, eine effiziente Allokation knapper Infrastrukturkapazitäten sowie die erforderliche Kostendeckung anzustreben. Zunehmende Skalenerträge beim Ausbau einer...

A power measure is monotone if a player with a larger weight is assigned at least as much power as a player with a smaller weight in the same weighted majority game. Failure of a power index to satisfy monotonicity is often considered a pathological feature. In this paper, we show that...

Uncertainty plays a significant role in evaluating climate policy, and fattailed uncertainty may dominate policy advice. Should we make our utmost effort to prevent the arbitrarily large impacts of climate change under deep uncertainty? In order to answer to this question we propose an new way...

We report the results of an uncertainty decomposition analysis of the social cost of carbon as estimated by FUND, a model that has a more detailed representation of the economic impact of climate change than any other model. Some of the parameters particularly influence impacts in the short run...

We study price efficiency and trading behavior in laboratory limit order markets with asymmetrically informed traders. Markets differ in the number of insiders present and in the subset of traders who receive information about the number of insiders present. We observe that price efficiency (i)...

We examine the effectiveness of three democratically chosen rules that alleviate the coordination and cooperation problems inherent in collectively managed common-pool resources. In particular we investigate how rule effectiveness and rule compliance depends on the prevailing local norms and...

Several recent empirical and theoretical studies have revived interest in the relationship between the level of the exchange rate and economic development. This paper develops a dynamic model based on the Ricardian framework with a continuum of goods to consider the issue from a somewhat...

This paper studies tests of calendar effects in equity returns. It is necessary to control for all possible calendar effects to avoid spurious results. The authors contribute to the calendar effects literature and its significance with a test for calendar-specific anomalies that conditions on...
