The authors present a comprehensive synthesis and evaluation of the published scales measuring the components of the decision making process in ethical situations using the Hunt-Vitell (1993) theory of ethics as a framework to guide the research. Suggestions for future scale development are also provided.  相似文献

In 1996, the Korean mobile communication market was the first in the world to commercialize the code division multiple access (CDMA). Since then, the voice-based mobile phone market has continued to grow and has now reached near saturation. Having recognized the potential of the mobile data service as a new source of profit, telecommunication operators are scrambling to evolve 3.5 generation (3.5G) technology in order to lead market competition. Recently, the Korean 3.5G mobile telecom market has faced stiff competition from CDMA-based EVDO Rev.A and global system for mobile telecommunications (GSM)-based high-speed downlink packet access (HSDPA). In addition, the world's first wireless LAN-based wireless broadband internet (WiBro) service was commercialized in June, 2006. This paper reviews the current status of the 3.5G technology and analyzes the service standardization strategies from the viewpoint of technological evolutions. This paper also suggests implications for Korea's specific circumstances where different mobile telecom technologies complement and compete with one another. Korea's experiences may serve as important lessons for other countries or operators who try to introduce the 3G and look beyond mobile telecom technologies.  相似文献

This paper addresses two very old issues in human society: espionage and double crossing. Our major conclusion points out that there will be a serious over rewarding problem in the direct mechanism due to double crossing in espionage, and a competitive mechanism with a relative performance regime can possibly mitigate the over rewarding problem and still extract the information.   相似文献

Automatic order matching systems have emerged as an electronic alternative to traditional markets. In current automatic order matching systems, price and quantity are the only product dimensions used for the order matching. However, a single-commodity market is made up of many heterogeneous goods which are close to each other but different in qualities and delivery conditions. Price and quantity are important but represent only parts of product attributes that commodity traders want to take into account. This study aims to extend current automatic order matching systems by diversifying product dimensions. An intelligent order matching system not only maximizes the total transaction volume based on the price and quantity but also satisfies traders' qualitative preferences over attributes other than price and quantity. The intelligent order matching mechanism combines an economic model with a preference model to incorporate both quantitative and qualitative utility of market participants. Constraint logic programming is investigated as a new information technology to structure and implement the intelligent order matching system.  相似文献

Entry deterrence and innovation in durable-goods monopoly   总被引:1,自引:0,他引:1  
This paper investigates the efficiency of innovation investments in a durable-goods monopoly when a potential entrant threatens to innovate as well. We show that the durability of the good endows the monopolist with the power to discourage rival innovation since current sales alter the demand for a new generation of the good. The equilibrium is therefore determined not only by the incentive for intertemporal price discrimination in durable-goods monopoly, but also by the incumbent's concern for maintaining the technological leadership. We demonstrate that entry deterrence followed by no innovation always implies underinvestment in innovation.  相似文献

Changing trends and the nature of the work force dictate increased personal responsibility by employees and expanded use of self-management practices. Nevertheless, organizations also feel the need to maintain external control. We propose a progressive view of accountability theory which can resolve the dilemma of how internal and external control can effectively coexist. Success of accountability forces is determined primarily by the relationship between the principal (party to whom one is accountable) and the agent (employee). The agent’s felt responsibility is enhanced to the extent that accountability leads to the structuring of expectations, the agent’s perceptions of the task or activity as significant, and the agent’s perception of control over the situation. Propositions that may be used to guide future research are offered throughout the article.  相似文献

Previous studies of human service facility spillovers on residential property values have been inconclusive, and have failed to take into account the effects of racial segmentation of housing markets. Likewise, studies of racial discrimination in urban housing markets and price differentials between white and nonwhite areas of the city have failed to consider the impacts of service facilities on prices. This study develops an hedonic price model of housing services in a racially segmented housing market, which considers a variety of human service facilities and their spillover effects. Model results for Oakland, California in 1976 indicate that facilities significantly affect housing prices both positively and negatively, and that these effects vary by racial submarket. Implications of these findings for the interpretation of past discrimination studies, facility impact studies, and social policy are considered.  相似文献

Historically, the lack of competition in developing countries has resulted in highly concentrated domestic industries that suffer from diseconomies of scale but prosper behind high walls of protection. Liberalization is expected to reverse this trend but at what cost? This article utilizes an import demand framework to examine the potential impact of trade liberalization on the manufacturing sector in the Caribbean using the case of Barbados. The results indicate that the manufacturing industry could encounter tremendous price competition, which could compromise the future survival of these industries. The study recommends that industries reorganize production processes to increase efficiency, which will allow them to compete effectively in the new global trading environment. These results may also be applicable to the wider Caribbean.  相似文献

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.  相似文献
