istortions under the value-added tax (VAT) arise partly from the exemption of specific services and sectors. This paper develops an analytical model that is applicable to any sector characterized by asymmetric VAT exemptions of services and activities. We analyze the effects of such asymmetric tax regimes on market shares, optimal prices, tax receipts, and social welfare. The analytical model shows how asymmetric VAT exemptions distort competition by strengthening the competitive position of non-rated firms. The net effect of such tax exemptions depends on the fraction of VAT-rated inputs versus the fraction of non-rated customers. We further elucidate main competitive impacts of VAT policies, while showing their consequences on overall welfare by presenting simulation results based on a calibrated quantitative model of a selected sector. Our paper provides guidance on how to resolve the policy trade-off between a level playing field in the market, consumer surplus, and government tax revenue.
This chapter analyzes how one particular governance mechanism affects the performance of research teams. We look at an external requirement for interdisciplinarity and internationality of Research Training Groups (RTGs) and study how their performance is affected. We expect to observe two countervailing effects with changes in interdisciplinarity and/or internatio-nality: first, increased performance due to an increase in productive resources and a second, decreased performance due to increased team problems (communication, conflicts etc). Since both effects are expected to vary with the disciplinary field of research, we separate our analysis for the Humanities & Social Sciences in comparison to the Natural & Life Sciences and indeed find different effects in the different disciplinary fields. Furthermore, we separately analyze the effects of interdisciplinarity on the one hand and internationality on the other hand. We conclude that the effectiveness of a particular governance mechanism varies substantially between the disciplinary fields and for the type of heterogeneity under consideration. Therefore governance of research should be either precisely engineered to a particular disciplinary field and a given type of heterogeneity or it should offer a menu of options that allows research teams to choose from according to their specific needs.
Für KMU wird eine aussagekräftige Rechnungslegung immer wichtiger. Zentral ist ein vernünftiges Kosten- und Nutzenverhältnis. Zur Verbesserung der Rechnungslegung existieren heute zwei Optionen: Swiss GAAP FER und IFRS.
Seit dem 1. Januar 2009 sind kotierte IFRS-Anwender verpflichtet, eine Segmentberichterstattung nach IFRS 8 zu erstellen. Anhand einer Analyse der Geschäftsberichte 2009 der an der SIX Swiss Exchange kotierten Unternehmen soll ein Überblick über die erstmalige Anwendung von IFRS 8 "Operating Segments" in der Schweiz gewonnen werden.
