Since the outbreak of the financial and economic crisis, confidence in politicians as well as the economists in their advisory expert panels seems to be at an all-time low. Why do politicians reject science-based advice unless it fits into their political agenda? Are economists misunderstood by politicians and vice versa? The tension between the ideal of evidence-based policy-making and the reality of policy-based evidence-making is hardly a new phenomenon. Therefore, the expectation that Donald Trump, the Brexiteers and European populists will necessarily disappoint their voters because they simply cannot deliver what they have promised is misleading. Experts would be well advised to use the debate on the post-factual era as an impetus to reflect critically on their profession. One opinion expressed in this Zeitgespräch is that the contested societal and political impact of modern economics is due to its restricted scientific self-concept. A more open, pluralistic and transdisciplinary self-definition of economics would strengthen its societal influence. Another contributor ponders the proper incentives to persuade academic economists to provide economic policy advice. Key is the independence of advisory institutions like the German Council of Economic Experts. The selection of people with the best scientific qualifications will ensure the reputation of such institutions. 相似文献

Farmers,Middlemen and Exporters: A Model of Market Power,Pricing and Welfare in a Vertical Supply Chain 下载免费PDF全文
Markets for cash‐crops in developing countries are typically characterized by a concentration of buyer power at different levels of the supply chain. For instance, small‐scale coffee farmers sell their produce to a middleman, who in turn sells the coffee onward to an exporter, often a foreign multinational, with monopsony power in the hands of the purchasers at both levels. We analyze pricing behavior and welfare with different assumptions regarding market power. In particular, we show that a more powerful exporter is likely to benefit the producers and may even lead to higher welfare for the producer country as a whole. 相似文献

To solve the problem of illegal landings this article proposes a new tax mechanism based on the regulator's own aggregate catch estimates and ex ante self-reports of planned catch by fishermen. We show that the mechanism avoids illegal landings while ensuring (nearly) optimal exploitation and generating (nearly) correct entry and exit incentives. Finally we simulate the mechanism for the Danish cod fishery in Kattegat to obtain a rough indicator of the size of the tax. It turns out that the average tax payment as a percentage of profit is surprisingly low. 相似文献

Solidarity and Probabilistic Target Rules 总被引:3,自引:0,他引:3
We consider a probabilistic approach to collective choice problems where a group of agents with single-peaked preferences have to decide on the level or location of a public good. We show that every probabilistic rule that satisfies Pareto efficiency and "solidarity" (population-monotonicity or replacement-domination) must equal a so-called target rule. 相似文献

Collective decision problems are considered with a finite number of agents who have single-peaked preferences on the real line. A probabilistic decision scheme assigns a probability distribution over the real line to every profile of reported preferences. The main result of the paper is a characterization of the class of unanimous and strategy-proof probabilistic schemes with the aid of fixed probability distributions that play a role similar to that of the phantom voters in H. Moulin (Public Choice35 (1980), 437-455). Thereby, the work of Moulin (1980) is extended to the probabilistic framework. Journal of Economic Literature Classification Numbers: D71, D81. 相似文献
