Untersuchung verschiedener Handelsstrategien für Wind- und Solarenergie unter Berücksichtigung der EEG 2012 Novellierung

The new EEG 2012 law opens up for more parties to participate in the trading of wind and solar power, because of the bonus system that now compensates everybody for all market relevant costs, not only the Transmission System Operators. Therefore it can be expected, that the trading of renewable energies by private parties will increase. One of the central questions to be answered is how efficient does a balance responsible party have to be to stay competitive also with a small pool. The quantification of balance costs for different trading strategies is however complex and non-trivial. We propose a methodology in this study that accounts for this fact. Additionally, we analyse and show the requirements and the monetary value of Intra-Day trading for the handling of wind and solar power. The trading strategies proposed in this article make use of an uncertainty band around the forecasts used in the Intra-Day, in order to avoid double trading and thereby reducing the total balancing volume and the associated costs.     

Increasing Diversity in Telecommunications Ownership and Increasing Efficiency in Spectrum Auctions by Breaking the Link Between Capital Market Discrimination and FCC Spectrum Auction Outcomes

In Section 309(j)4(D) of the Communications Act, the Federal Communications Commission (“FCC”) is required to increase opportunities for minority groups to participate in the provision of spectrum based services. In Adarand Construction, Inc. v. Pena, the Supreme Court held that race-based government programs were subject to strict scrutiny. That is race-based programs must serve a compelling governmental interest such as remedying past discrimination, and must be narrowly tailored to serve that interest. Against this backdrop, a simple theoretical model is developed that explains the relationship between capital market discrimination and outcomes in FCC spectrum auctions. Given capital market discrimination and all other factors being equal, it is shown that a minority firm has zero probability of winning in an auction for spectrum. In addition, it is proven that, if equal bidding credits are given to all firms, if there is capital market discrimination, and if all other things are equal, the minority firm has a zero probability of winning in a spectrum auction. It is shown that a policy of auctioning spectrum, when there is capital market discrimination, is an inferior policy among policies that can be used to allocate spectrum. Finally, a policy of auctioning spectrum, when there is capital market discrimination, results in an inefficient auction. These theoretical results and the empirical literature on capital market discrimination suggest that the FCC is implicitly discriminating against minorities through its auctioning of spectrum under conditions of discrimination in capital markets. The results imply that race-based programs are necessary/justified in order to increase diversity in telecommunications ownership and increase the efficiency of FCC Spectrum Auctions. Given possible legal remedies, the paper contains a critical “audit”/analysis of the FCC’s lending practices under the FCC’s installment payments. Legislative proposals for creating some new form of credit/installment payment in conjunction with some experienced financial institution(s) are summarized and reviewed.     

Structural changes in exports of an emerging economy: Case of Turkey

This paper indicates that Turkish exports are subject to structural changes as Turkey integrates into global production networks. Integration, which leads vertical specialization in production and changes in the commodity composition of Turkish exports in favor of non-traditional commodities, paces up during economic reform periods. As the export shares of non-traditional commodities, which have higher import and income sensitivity but lower real exchange rate elasticity, increases, coefficients of the aggregate export function change accordingly. Nevertheless, high import and income elasticity of exports imply that the global growth pattern plays a significant role in determining exports of Turkey.     

What characterizes Chinese consumer behavior? A cross-industry analysis of the Chinese diaspora in Japan

In order to profit from China??s enormous business opportunities, international firms need to know Chinese consumer preferences. To learn more about intrinsic Chinese consumer preferences and their distinction from other Asian consumer preferences, this study analyzes differences in the formation of customer satisfaction, repurchase intent, and word-of-mouth intent between Chinese-born and locally born consumers in Japan. Verifying culture-based hypotheses, cross-industry analyses show that Chinese-born consumers pay less attention to the public brand image and risk-related switching costs, but more attention to quality expectations, perceived value, experienced usefulness, and financial switching costs than Japanese consumers. Marketing strategies should account for these preference structures.     

Qui docet discit

Academic economists play many roles; researchers, policy advisor, teacher, etc. While each of these roles is important for the career advancement of an economist, the most important role of academic economists is teaching future citizen economists. It is incumbent upon economists qua teacher to prepare them to make sense of the world they will inhabit. We must, therefore, not teach economics, at least at the introductory level, as if it is the first course on the way to a Ph.D., but as if it is the last class the students will ever take in economics. A consistently subjectivist economics is the best way to teach future citizen economists. When students understand economics as something that helps them make sense of the world, rather than a course in applied mathematics, they will be better citizen economists less likely to fall prey to those selling them free lunches.
