This paper deals with a specific vertical assignment of public functions in a federation: Two levels of government share both the same tax source and expenditure on a productivity increasing public service. We consider surplus maximizing Leviathan governments which provide public services in order to increase their potential tax base. The Nash equilibrium is characterized by overtaxation and relative to surplus maximization—depending on whether or not the public goods are sufficiently complementary with the entire tax base—either underprovision or overprovision of the public service. The implications of these results, in terms of welfare and potential use for earmarking taxes are also considered. 相似文献

Is advertising anticompetitive? One school of thought in industrial economics holds that advertising increases profits and reduces consumer welfare by creating spurious product differentiation and barriers to entry. Another school focuses on the informative character of advertising, claiming that advertising makes markets more competitive and reduces profits by supplying consumers with information about price and quality. We distinguish these views by examining the effect of advertising on competition in the US automobile industry. Our data include advertising, sales, profit, and market-share figures for General Motors, Ford, and Chrysler over a 25-year period from 1970 to 1994.We ask if advertising increases or decreases profitability, controlling for market structure and other factors affecting demand.Wefind that these firms cannot increase their profits above normal levels by increasing their advertising expenditures. This evidence supports the view that advertising serves primarily to transmit information, not to create entry barriers. 相似文献

Market Designs for a Completely Renewable Power Sector 总被引:1,自引:1,他引:0
The article discusses whether the current German electricity market design is suitable for an electricity system completely based on renewable sources, and analyzes alternatives. Such a system becomes ever more likely due to the phase-out of nuclear power and the carbon reduction targets. Various existing scenarios for a completely renewable electricity system are analyzed and compared with respect to the contribution of different renewable technologies. Challenges for the market design arising from the differences between the current and a completely renewable system are identified??notably problems with cost recovery and investment incentives, an increased need for balancing and/or intraday adjustments, an increased diversity of actors, grid congestion and the continuing occurrence of market power. The current market design??s ability to solve these issues is assessed with the result that all but the critical problem of investment incentives and cost recovery can be solved by adapting certain rules. A?comparison with other suggested market designs reveals that some designs could ensure cost recovery and investment incentives. However, these market designs have other drawbacks. Therefore, the identification of the optimal market design for a completely renewable electricity system requires further research regarding the qualitative and quantitative effects of different changes to the current market design. The article concludes by developing concrete policy recommendations. 相似文献

We consider a tournament between two workers of different abilities who choose both human capital investment and effort. The employer can influence the workers’ behavior by determining the sequence of human capital investments, i.e. the training design. The workers can either invest simultaneously or sequentially with the favorite being the first mover or sequentially with the underdog as first mover. The results show that the outcome of the tournament crucially depends on the employer’s choice of training design and on the ability difference between the workers. If the two workers clearly differ in their abilities the employer will prefer simultaneous human capital accumulation. However, if the abilities of the two workers are rather similar the employer optimally chooses sequential human capital accumulation with the underdog being the first mover. 相似文献

In this paper we present a statistical analysis of four foreign exchange spot rates against the U.S. Dollar with several million intra-day prices over 3 years. The analysis also includes gold prices and samples of daily foreign exchange prices over 15 years. The mean absolute changes of logarithmic prices are found to follow a scaling law against the time interval on which they are measured. This empirical law holds although the distributions of the price changes strongly differ for different interval sizes.Systematic variations of the volatility are found even during business hours by an intra-day analysis of price changes. Seasonal heteroskedasticity is observed with a period of one day as well as one week as the result of an analogous intra-week analysis; taking this into account is necessary for any future study of intra-day price change distributions and their generating process. The same type of analysis is also made for the bid-ask spreads. 相似文献
