We conduct a survey of German tax professionals (tax advisors and revenue agents) and laymen to examine whether tax experts more accurately forecast the outcomes of five real cases from the German Federal Fiscal Court. With an average of 2.39 correct predictions among experts and an average of 2.49 correct predictions among laymen, our results reveal no significant difference in forecasting accuracy between the two groups. Additionally, neither general nor task-specific tax expertise increases the experts’ forecasting accuracy. This unpredictability of tax court decisions indicates that accounting rules and taxpayer penalties that rely on accurate predictions of tax court decisions may need to be re-evaluated. Moreover, our results indicate the existence of two types of ‘advisor bias’. First, tax advisors exhibit a significantly higher level of overconfidence in comparison to other experts (i.e. revenue agents) and laymen. In particular, they believe that they correctly predict, on average, 1.52 more cases than they actually do. Second, we find some evidence indicating that tax advisors acting as client advocates form stronger appeal recommendations than revenue agents. 相似文献

Are initial competitive advantages self-reinforcing, so that markets exhibit an endogenous tendency to be dominated by only a few firms? Although this question is of great economic importance, no systematic empirical study has yet addressed it. Therefore, we examine experimentally whether firms with an initial cost advantage are more likely to invest in marginal cost reductions than firms with higher initial costs. We find that the initial competitive advantages are indeed self-reinforcing, but subjects in the role of firms overinvest relative to the Nash equilibrium. However, the pattern of overinvestment even strengthens the tendency towards self-reinforcing cost advantages relative to the theoretical prediction. Further, as predicted by the Nash equilibrium, mean-preserving spreads of the initial cost distribution have no effects on aggregate investments. Finally, investment spillovers reduce investment, and investment is higher than the joint-profit maximizing benchmark for the case without spillovers and lower for the case with spillovers. 相似文献

In spite of all protestations and exhortations it is a fact that trade liberalization, the modern version of free trade, is caught in a crisis. Professor Detlef Lorenz is here analysing the causes of this crisis and suggesting alternatives for a future liberalization policy. 相似文献

We give a complete solution to the problem of minimizing the expected liquidity costs in the presence of a general drift when the underlying market impact model has linear transient price impact with exponential resilience. It turns out that this problem is well-posed only if the drift is absolutely continuous. Optimal strategies often do not exist, and when they do, they depend strongly on the derivative of the drift. Our approach uses elements from singular stochastic control, even though the problem is essentially non-Markovian due to the transience of price impact and the lack in Markovian structure of the underlying price process. As a corollary, we give a complete solution to the minimization of a certain cost-risk criterion in our setting. 相似文献

Relatively few empirical studies address the question of generic relationships between consumers and brands. But a relationship‐oriented brand communication seems to have become increasingly important to companies. In this article, the authors present details of a study on generic consumer–brand relationships conducted in Germany. Based on the data of more than 900 consumers, four different types of consumer–brand relationships emerge, characterized as “best friendship,” “unemotional purpose‐based relationship,” “loose contact,” and “happy partnership.” An extended analysis of the data using advanced statistical methods supports these findings to a high degree. Furthermore, as the results of the extended analysis also suggest, numerous well‐known brands often appear within less favorable relationships like “unemotional purpose‐based relationship” and “loose contact.” These findings indicate important shortcomings of relationship‐oriented brand management in many companies and suggest the need for further work in this area. 相似文献

After the euro changeover at the beginning of 2002, a marked discrepancy emerged between perceived inflation and inflation
as measured by the consumer price index. To what extent are consumers still overestimating price developments even now? How
reliably is this phenomenon measured by the “Index of perceived inflation” developed by Professor Brachinger? What are the
findings of the consumer surveys conducted on behalf of the European Commission?

Zur Zeit wird das Stra?ennetz in Deutschland aus den Haushaltsmitteln der ?ffentlichen Kassen finanziert. In den letzten Monaten
wurde auf Ministerebene wiederholt die Einführung einer entfernungsunabh?ngigen PKW-Vignette diskutiert. In welcher Form sollten
die optimale Bereitstellung und die Finanzierung des Stra?ennetzes aus finanzwissenschaftlicher Perspektive realisiert werden?
