Arguments about the existence of the so-called energy efficiency gap are typically based on evaluations of efficiency measures as investments whose end result is to reduce the cost of providing a given level of energy services. This article demonstrates that the investment approach tends to undervalue energy efficiency improvements because it omits the increase in utility that results from the consumer's substitution of energy services for other goods. The substitution occurs because the efficiency measure reduces the marginal cost (implicit price) of energy services. Sample calculations based on a Cobb-Douglas utility function are used to illustrate the potential size of the undervaluation of efficiency investments. 相似文献

Small accounting practices (SAP), most of which are sole principals, are an important part of the accounting profession and the Australian economy. This exploratory study identifies issues and challenges experienced by small accounting principals in Far North Queensland, Australia. The findings generally correspond with previous research, ranking staffing and keeping up to date through professional development as key areas of concern, and also highlighting the expectation gap between SAP principals and their clients. Stress emerged as a major concern for principals, and new areas of possible conflict of interests were uncovered. A number of potential areas for future research, including comparative studies in city and suburban areas, have been identified. 相似文献

This study investigated (1) whether potential future purchasing agents were predisposed to accept gratuities or whether the practice of gratuity acceptance is a manifestation of the job itself, (2) whether the existence of a code of ethics forbidding gratuity acceptance curtails the occurrence, and (3) whether disparities in ethics policies between the sales and purchasing functions affect gratuity acceptance. Hypotheses based upon the concepts of organizational concern and institutionalized ethics are developed and empirically tested. Results suggest that future purchasing agents are predisposed to accept gratuities and that formal written ethics policies decrease the acceptance of gratuities. Disparities in ethics policies between the sales and purchasing functions concerning gratuities failed to affect gratuity acceptance significantly.Gregory B.

The law of one price (LOOP) is an essential foundation of both the pure theory of trade and monetary theory. Strictly speaking, the law relates to prices of individual commodities. However, empirical tests of LOOP have often relied on aggregated data. In this paper, a model is derived and estimated using price data for 15 selected inputs in New Zealand agriculture. The results offer no support for the LOOP in the short run, and the results for the long run are mixed. It may be inappropriate, therefore, to assume that the LOOP holds generally in modelling exercises, particularly when models are used for policy purposes. 相似文献

The end of the cold war has elevated environmental issues to the highest level of concern for humanity while creating a world order dominated by the United States of America and other Western nations. This new power structure may likely lead to increased business activity in many parts of the world, as nations formerly preoccupied with the cold war turn their attention to economic development. This paper examines the linkages among ethics, economic development and protection and restoration of the environment in The New World Order.Emily F.

This study investigated how partners' self-reported opportunism and shared decision making varied by culture in international joint ventures (IJVs) with the Japanese. Data were gathered by a mail survey of senior officials in IJVs located in 11 host countries. Significant differences were found between partners from Western cultures and the Japanese, but not between other Asians and the Japanese. Indirect effects suggest that shared decision making neutralizes cultural tendencies toward opportunism. Results indicated that opportunistic tendencies did not diminish as the IJV relationship aged, and that shared decision making did diminish as the relationship aged. 相似文献

Can economically efficient outcomes be obtained and sustained in the absence of externally enforced property rights? We study the evolutionary properties of a game that exhibits two well-defined Nash equilibria: one generates an inefficient outcome while the other set generates an efficient outcome supported by the potential for retaliation. Although standard forward-looking refinements eliminate the efficient equilibrium, neither equilibrium type satisfies strict evolutionary stability criteria. However, both types of equilibrium define strategies that are neutrally stable, which makes them vulnerable to drift in dynamic environments. We conduct computer simulation experiments in which players learn adaptively via a tournament selection mechanism called sophisticated experimentation. Our simulations demonstrate that while the system spends a disproportionately high proportion of time in the inefficient equilibrium set, the efficient equilibrium is pervasive as the system drifts back and forth between the equilibrium sets, never settling on one or the other. 相似文献

A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate alternative management interventions. Data were collected from the Food Animal Health Resource Management System (FAHRMX), Today's Electronic Planning (TELPLAN), Today's Electric Farm Accounting (TELFARM) databases and secondary sources at Michigan State University. A case study of cystic ovaries was analysed using the model. The results showed that it is more economical to treat cystic ovaries than not to treat, and treatment with Gonadotropin Releasing Hormone (GNRH) was superior to Human Chrionic Gonadotropin (HCG). Four to five lactations were the optimum for keeping a dairy cow to replacement and it was estimated that there is a loss of US$0.45 per day of extended calving interval (days open beyond the optimal 70 days). 相似文献
