Incomplete Markets and Security Prices: Do Asset-Pricing Puzzles Result from Aggregation Problems?

This paper investigates Euler equations involving security prices and household-level consumption data. It provides a useful complement to many existing studies of consumption-based asset pricing models that use a representative-agent framework, because the Euler equations under investigation hold even if markets are incomplete. It also provides a useful complement to simulation-based studies of market incompleteness. The empirical evidence indicates that the theory is rejected by the data along several dimensions. The results therefore indicate that some well-documented asset-pricing puzzles do not result from aggregation problems for the preferences under investigation.     

Asian tax review: Going green in Red China

Taxes in China are no laughing matter. The rules change often, and it takes a lot of energy to keep up. As more foreign investors enter the Chinese market, drawn by its size and dynamic entrepreneurial spirit, it can be very helpful to get frequent updates on the latest tax policies. This article talks about China's growing energy needs, increased interest in green technology, and how best to incentivize developers. The author, an expert on taxes, also provides updated information specifically from Hong Kong. © 2008 Wiley Periodicals, Inc.     

Workforce or workfare? The optimal use of work requirements when labour is supplied along the extensive margin

This paper explores the use of workfare as part of a tax mix when labour supply responses are along the extensive margin. In an economy where the government has a priori chosen any tax‐and‐benefit schedule, we show that, despite their common goal of providing additional incentives for individuals to enter the labour force, workfare and an earned income tax credit are at odds with each other. We also show that, in the presence of an optimal nonlinear income tax, introducing unproductive workfare is always suboptimal when individuals face the same disutility of being on workfare. When this disutility is heterogeneous, unproductive workfare may be a useful policy tool.     

Gold price risk and the returns on gold mutual funds

A model is presented for estimating the theoretical gold price elasticity of the value of mutual funds investing in gold mining companies. The theoretical elasticity shows that if the funds invest in companies whose assets are comprised primarily of operating gold mines, then the return of an investment in the fund will be at least as great as an investment in gold (i.e., the gold price elasticity of the gold fund is greater than 1). Empirical tests of the above propositions are presented. Empirical tests also show, however, that the gold mutual funds contain a substantial amount of risk which is not explained either by market risk or gold price risk. Accordingly, gold mutual funds and gold bullion do not bring identical risks to an investor's portfolio.     

Understanding Empirical Boundaries: A Systems-Theoretical Avenue in Border Studies

The aim of this contribution is to present a conceptual framework with potential application across the interdisciplinary field of border studies. This framework should embrace interdisciplinarity and the contextual nature of borders. Based on the systems theory of Niklas Luhmann, it elaborates an understanding of borders as being related to a dynamic process of social bordering/bounding processes that involves spatial, social, and conceptual boundaries. By introducing the notion of ‘empirical boundary’, our framework aspires to bridge the gap between (radical) constructivist theorising and the analysis of physical realities involved in the (re)production of boundaries.     

Gesundheitsfonds — effizientere Steuerung des Gesundheitssystems?

In 2009 the German central health fund was implemented. It was the result of a political compromise. One political party intended to equalise the risk structure among 130 different health care funds, and the other wanted to intensify competition and to improve efficiency among the different health insurances. The fund is flanked by a health-based risk adjustment and is aimed at sustainably ensuring the funding of the statutory health insurance system. It also constitutes the basis for competition among statutory health care funds, securing quality and efficiency in health care provision. To cover additional expenditures, health insurers had to charge flatrate premiums. A new law, which will come into effect in January 2015, will oblige health insurers to charge income related contributions. It is not clear how this will change competition among insurers. The federal government will not need to finance subsidies to low income individuals anymore. Income redistribution will only take place within the public health insurance system, exempting the privately insured and public servants from supporting low income individuals. The authors claim that the health care fund will not succeed in its aim of securing a sustainable financial basis for the statutory health insurance system. Most of the authors argue that there is no evidence of greater efficiency thus far, and they offer proposals on how to achieve improved performance.     

(Un)Ethical Behavior and Performance Appraisal: The Role of Affect,Support, and Organizational Justice

Performance appraisals are widely used as an HR instrument. This study among 332 police officers examines the effects of performance appraisals from a behavioral ethics perspective. A mediation model relating justice perceptions of police officers’ last performance appraisal to their work affect, perceived supervisor and organizational support and, in turn, their ethical (pro-organizational proactive) and unethical (counterproductive) work behavior was tested empirically. The relationship between justice perceptions and both, ethical and unethical behavior was mediated by perceived support and work affect. Hence, a singular yearly performance appraisal was linked to both ethical and unethical behaviors at work. The finding that ethical and unethical aspects of employee behavior share several of the same organizational antecedents, namely organizational justice perceptions, has strong practical implications which are discussed as well.     

New Developments in Soviet Advertising and Marketing Theory

This paper contrasts Soviet and Western advertising and marketing theory, and explains how Soviet theory has progressed in recent years. Soviet advertising practice has been adversely affected by the central planners' aim of regulating advertising, as well as consumption, so that demand is not stimulated beyond what is thought to be ‘rational’ or desirable. However, without abandoning their traditional product orientation, Soviet marketing theorists are developing the idea that consumer interests should be more important in product development. Moreover, in sharp contrast to previous Soviet practice, market segmentation is being examined as a means to increase the effectiveness of advertising. However, the omission of the important geographical and national group variables from this segmentation strategy implies that political considerations will remain paramount in any changes in theory or practice.
