Analyse der Marktaussichten von Biogasanlagen

Without guaranteed compensation, granted by the German Renewable Energy Sources Act (Erneuerbare Energien Gesetz/EEG), biogas plants compete with all other plant types on the market for electrical energy. However, exchange-based electricity products do not currently permit an economically viable operation of biogas plants owing to their cost situation.     

Retailing Innovations in a Globalizing Retail Market Environment

In recent years, the combination of economic growth and population growth in emerging markets and less developed markets has accelerated the progression of globalization of retailing and globalization by retailers. The challenges faced by global and globalizing retailers (retailers who currently have or intend to establish a market presence in mature markets, emerging markets and less developed markets) can be more daunting compared to those faced by firms in other industries such as automobiles, steel, and computers. Retailing innovations that are responsive to the characteristics of distinctive national markets and broader aggregations of markets such as mature, emerging and less developed markets are critical to the success of global and globalizing retailers. Against this backdrop, this paper focuses on retailing innovations in the context of a globalizing retailing environment. It attempts to shed insights into the characteristics of retailing innovations conducive to superior performance in distinctive national markets and across broader aggregations of markets. Towards this end, we first examine the environmental conditions of markets in different development stages, namely mature, emerging and less developed markets, and explore consumer based, industry based, and legal/regulatory based challenges faced by globalizing retailers in these markets. Second, we show how these challenges can be transformed into opportunities with retailing innovations. We conclude with a roadmap for future research and present propositions on future development with respect to retailing innovations in these markets.     

Longevity Risk Management in Singapore's National Pension System

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore's Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public‐sector provider for such annuities. This article evaluates the money's worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market.     

The effectiveness of corporate codes of ethics

While the focus on business ethics is increasing in business school curricula, there has been little systematic scholarly research on the forces which bring about ethical behavior. This article is intended as a first step toward that research by creating a catalogue of hypotheses concerning the efficacy of corporate codes of ethics. The hypotheses are drawn from studies of compliance with law and court decisions and theories of legitimacy, authority, public policy making and individual behavior. Hypotheses are proposed based on the structure of the organization, the source of the code of ethics within the organization, the content of the code, sanctions for noncompliance, protections for refusal to engage in unethical behavior, and rewards for compliance.Dr. Steven Weller has written extensively on problems of court process and organizational behavior. He possesses a J.D. and a Ph.D. in Political Science and has taught both in Business Law and in Political Science. He is presently a solo law practitioner, teacher and research consultant in Boulder, Colorado.     

Usefulness of the newly revised composite index of leading indicators as a quantitative predictor

This paper compares the performance of the current and earlier versions of the Commerce Department's Composite Index of Leading Indicators as predictors of quantitative (percentage) changes in real GNP. Almon-type distributed lag functions are estimated over a sample period covering the years 1948–1970. Tests of predictive accuracy focus on the post-sample period 1971–1975. The results, in terms of three commonly accepted measures of forecast accuracy (root mean square error, mean absolute error and Theil's U), indicate that the new index performs marginally better than the best of the older versions.     

Loans of the revolution: how Mexico borrowed as the state collapsed in 1912–13

This article assesses why the French and US banks Paribas and Speyers underwrote a series of loans to revolutionary Mexico in 1912 and 1913, when the state was in the process of collapsing. This is a case of a war debt that failed to prevent the borrowing government from suspending payments and subsequently falling. Based on unpublished primary documents, the article shows that the 1913 loan involved a conflict of interest. The credit delayed a default and sustained the price of Mexican securities while Paribas, its main underwriter, was liquidating its Mexican portfolio. Evidence also suggests the existence of asymmetry of information. Paribas accessed pessimistic but accurate first‐hand information on Mexico, while the public read over‐optimistic press reports. Paribas forced the government to sell the bonds on the primary market at a price that was low, controlling for publicly available data. It subsequently sold the bonds at a margin on the secondary market. An additional reason for the lending is the Nacional railway, a state‐owned company that used a share of the funds to pay its debt. More exposed to Mexico than Paribas, the small and internationalized Speyers held the bad bonds it had underwritten.     

Combining Sources of Preference Data for Modeling Complex Decision Processes

We review current state-of-the-art practices for combining preference data from multiple sources and discuss future research possibilities. A central theme is that any one data source (e.g., a scanner panel source) is often insufficient to support tests of complex theories of choice and decision making. Hence, analysts may need to embrace a wider variety of data types and measurement tools than traditionally have been considered in applied decision making and choice research. We discuss the viability of preference-stationarity assumptions usually made when pooling data, as well as random-utility theory-based approaches for combining data sources. We also discuss types of models and data sources likely to be required to make inferences about and estimate models that describe choice dynamics. The latter discussion is speculative insofar as the body of literature on this topic is small.
