The paper explores effects of the revision of the system of fiscal equalisation in Germany as recently agreed upon by the federal and state governments. More specifically, using a simulation analysis, it explores the distribution of gains and losses associated with changes in horizontal and vertical fiscal flows. In addition, the paper determines the degree of fiscal redistribution. While the degree of fiscal redistribution is found to be reduced for major revenue sources, local tax revenues are subject to much higher redistribution than under the status quo. Increases in local tax revenues might even result in total revenue losses for some states. 相似文献

Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems. 相似文献

Die meisten frisch gebackenen Mütter wollen stillen. Schlie?lich ist Muttermilch die beste Nahrung für das Baby. Leider trüben
Schmerzen die Stillbeziehung nicht selten so sehr, dass Mütter vorzeitig frustriert abstillen. Das muss nicht sein, wenn die
Pflegepraxis auch das Schmerzmanagement als selbstverst?ndlichen Teil der W?chnerinnenbetreuung betrachtet. 相似文献

This study considers the impact of diversification in types of technological alliances, resulting in alliance portfolio diversity, on various dimensions of a firm's performance, as they relate to exploration and exploitation. Using a large panel of innovative firms in the Netherlands, this study shows that partner type diversity in a firm's alliance portfolio has an inverted U-shaped relationship with productivity and radical innovative performance and a positive relationship with incremental innovative performance. Moreover, the results suggest that a lower level of diversity is needed to achieve an optimal level of productivity compared to radical innovative performance, whereas for incremental innovative performance a higher level of portfolio diversity appears to give the best performance. 相似文献

Environmental Taxes, International Capital Mobility and Inefficient Tax Systems: Tax Burden vs. Tax Shifting 总被引:1,自引:2,他引:1
This paper deals with the so-called double dividend of an environmental tax reform. In a model with only labor and a polluting input as factors of production, we find that society faces a trade-off between internalizing environmental externalities and raising revenues in the least distortionary way. However, if capital enters the production structure, an ecological tax reform may render the tax structure more efficient from a non-environmental point of view, thereby raising not only environmental quality but also private incomes. 相似文献

Corporate Hedging: The Relevance of Contract Specifications and Banking Relationships 总被引:2,自引:0,他引:2
This article examines the contribution of hedging to firm valueand the cost of hedging in a unified framework. Optimal hedgingand firm value are explicitly linked to firm risk, the typeof debt covenants and the relative priority of the hedging contract.It is shown that in some cases hedging is possible only if thecounterparty to the forward contract also holds a significantportion of the debt. Also, the spread in the hedging contractreduces the optimal amount of hedging to less than the minimum-variancehedge ratio. Among other results this article elucidates whysome firms hedge using forward contracts while other firms hedgein the futures markets, as well as why higher priority forwardcontracts are more efficient hedging vehicles.

Since voters are often swayed more by the personal image of politicians than by party manifestos, they may cast votes that are in opposition to their policy preferences. This results in the election of representatives who do not correspond exactly to the voters’ own views. An alternative voting procedure to avoid this type of election failure is prompted by the approach implemented in internet voting advice applications, like the German Wahl-O-Mat, which asks the user a number of questions on topical policy issues; the computer program, drawing on all the parties’ answers, finds for the user the best-matching party, the second-best-matching party, etc. Under the proposed alternative election method, the voters cast no direct votes. Rather, they are asked about their preferences on the policy issues as declared in the party manifestos (Introduce nationwide minimum wage? Yes/No; Introduce a speed limit on the motorways? Yes/No, etc.), which reveals the balance of public opinion on each issue. These embedded referenda measure the degree to which the parties’ policies match the preferences of the electorate. The parliament seats are then distributed among the parties in proportion to their indices of popularity (the average percentage of the population represented on all the issues) and universality (frequency in representing a majority). This paper reports on an experimental application of this method during the election of the Karlsruhe Institute of Technology Student Parliament on July 4–8, 2016. The experiment shows that the alternative election method can increase the representativeness of the Student Parliament. We also discuss some traits and bottlenecks of the method that should be taken into account when preparing elections. 相似文献
