Hedonic pricing and the spatial structure of housing data – an application to Berlin

Housing prices are largely determined by physical location. By applying the outsample prediction accuracy of rental prices as evaluation criteria, we examine whether the choice of the hedonic model additionally depends on the spatial structure of housing data, i.e. accounting for locational effects by either district fixed effects or spatial econometric modelling. Our results show that a generalised spatio-temporal model outperforms a district fixed effects model only if the spatial density – the weighted mean distance to nearest neighbours – is relatively small. Moreover, we use the required density thresholds to deduce a pseudo indifference curve, thereby showing that the ratio of the weighted spatial distance-to-the mean district diameter increases with the mean sample size per district. This emphasises the role of data structure and district choices for model selection. Differences in data can thereby serve as an explanation for contradictory findings in literature, whether spatial econometric methods or simple district fixed effects are used.     

Alle Sozialabgaben steuerlich berücksichtigen statt Solidaritätszuschlag abschaffen

The abolition of the German solidarity surcharge would favour higher incomes much more than lower incomes. Tax deductibility of all social contributions, however, would concentrate relief on average incomes, which are heavily loaded by social contributions. In addition, a monthly social security allowance of €150 could be introduced gradually in a budget-neutral manner.

Möglichkeiten zur Kompensation der kalten Progression: Wirkung in Österreich

Regardless of the latest tax reform the fiscal drag brings an additional tax burden of € 6.2 billion for the period 2016-2021 to Austrian taxpayers. In 2021 alone this fiscal drag will levy an additional € 2.17 billion. The study in hand gives an overview how other countries control the fiscal drag and analyses the effect of such adjustments in the Austrian tax system. Depending on the adjustment model, the range of the fiscal drag by 2021 lies between a tax burden of € 4 billion (tax brackets adjusted once the cumulative inflation reaches the 5 percent threshold) and between a tax reduction of € 1.6 billion (the tax system is adjusted to the development of nominal wages). In the latter case an adjustment leads to an over-compensation of the fiscal drag yielding a constant tax burden relative to income. For the entire elimination of the fiscal drag an annual inflationary adjustment of the tax brackets, tax credits and deductibles is necessary.     

Determinants of how individuals choose,eat and waste: Providing common ground to enhance sustainable food consumption out‐of‐home

The transformation of food consumption in wealthy economies is regarded as an essential measure to reach global sustainability goals. However, existing policies and research activities to change food consumption in the increasingly relevant out‐of‐home sector relate to a wide set of options on how to influence behaviours and may be criticized to lack a general focus. Against this background, our study provides a structured review of the existing research body on the determinants of individuals’ food choices and food consumption out‐of‐home. It structures the various research approaches and findings for 110 selected papers according to a general ecological framework where personal, social and environmental determinants for food behaviours are considered. By providing a collective overview and linking results for different behavioural aspects and settings, this study supports a more general understanding of consumer food behaviour in out‐of‐home settings. Consequently, it also provides a means to identify research gaps and to suggest relevant aspects for future research to draw from the combination of findings and to enhance sustainability in food consumption.     

Self-selection and variations in the laboratory measurement of other-regarding preferences across subject pools: evidence from one college student and two adult samples

We measure the other-regarding behavior in samples from three related populations in the upper Midwest of the United States: college students, non-student adults from the community surrounding the college, and adult trainee truckers in a residential training program. The use of typical experimental economics recruitment procedures made the first two groups substantially self-selected. Because the context reduced the opportunity cost of participating dramatically, 91 % of the adult trainees solicited participated, leaving little scope for self-selection in this sample. We find no differences in the elicited other-regarding preferences between the self-selected adults and the adult trainees, suggesting that selection is unlikely to bias inferences about the prevalence of other-regarding preferences among non-student adult subjects. Our data also reject the more specific hypothesis that approval-seeking subjects are the ones most likely to select into experiments. Finally, we observe a large difference between self-selected college students and self-selected adults: the students appear considerably less pro-social.     

The effect of wage dispersion on team outcome and the way team outcome is produced

The impact of intra-team pay dispersion on team productivity is a highly discussed issue. On the one hand, wage differentials provide incentives for higher employee effort. On the other hand, pay inequality may reduce team cohesiveness and increase feelings of relative deprivation leading to lower performance. Analysing nonlinear effects of wage dispersion in professional soccer, we find empirical evidence that team performance is strongest when there is either very high or very low wage inequality. Medium levels produce the weakest team performance. In addition, we show that the pay structure affects the team's playing style even after controlling for team and coach heterogeneity. We discuss the theoretical and managerial implications as well as the limits of generalization.
