This article uses a nonparametric test based on the arc‐sine law (see, e.g., Feller, 1965 ), which involves comparing the theoretical distribution implied by an intraday random walk with the empirical frequency distribution of the daily high/low times, in order to address the question of whether the abandonment of pit trading has been associated with greater market efficiency. If market inefficiencies result from flaws in the market microstructure of pit trading, they ought to have been eliminated by the introduction of screen trading. If, on the other hand, the inefficiencies are a reflection of investor psychology, they are likely to have survived, unaffected by the changeover. We focus here on four cases. Both the FTSE‐100 and CAC‐40 index futures contracts were originally traded by open outcry and have moved over to electronic trading in recent years, so that we are able to compare pricing behavior before and after the changeover. The equivalent contracts in Germany and Korea, on the other hand, have been traded electronically ever since their inception. Our results overwhelmingly reject the random‐walk hypothesis both for open‐outcry and electronic‐trading data sets, suggesting there has been no increase in efficiency as a result of the introduction of screen trading. One possible explanation consistent with our results would be that the index futures market is characterized by intraday overreaction. © 2004 Wiley Periodicals, Inc.

Much published work over the years has pointed to the differences between business-to-consumer (B2C) and business-to-business (B2B) marketing. An undesirable by-product of this sometimes misdirected distinction is that managers working within B2B environments have generally not considered the use of what are seen as B2C techniques, such as multivariate statistical analysis. This article is structured in three parts. First, the argument for the similarities between B2B and B2C marketing is developed; second, three different multivariate statistical techniques are presented and combined to form a practical tool kit for use by B2B managers on strategic, operational, and tactical levels; and third, the results of an application of the techniques in the life science research chemicals industry is reported, demonstrating that the tool kit substantially enhanced managerial understanding of customer decision processes. 相似文献

Comparisons to other consumers have been identified as particularly meaningful in shaping price fairness judgments, but why they should be so is not clear. The current work argues that fairness judgments reflect both the extent to which consumers receive what they believe they deserve and inferences about seller respect. We suggest that comparisons to consumers paying lower prices are a particularly potent source of unfairness because they highlight the violation of deservingness and readily communicate information about sellers’ opinions of consumers. Three experiments investigate these ideas. Implications for fairness theory and marketing are discussed. 相似文献

The Multi-Actor Multi-Criteria Analysis (MAMCA) is a methodology to evaluate different policy measures whereby different stakeholders’ opinions are explicitly taken into account. This paper describes the MAMCA methodology and how it has been used in the “Flanders in Action Process”. One of the objectives of this process is to turn Flanders into a top region in terms of mobility and logistics by attracting logistic activities with a large added value, realizing fluent and widely accessible mobility, a huge increase in traffic safety and a decrease of the environmental impact of transport. As there are a wide range of actors with different interests involved in this process, the MAMCA methodology was applied to evaluate a set of possible policy measures being proposed to reach this objective. An important advantage of this methodology is that it is able to support the decision maker in his final decision as the inclusion of different points of view leads to a general prioritisation of the proposed policy measures. 相似文献

Many economic and evolutionary theories have modeled cooperation as the evolutionary outcome of decisions made by autonomous,
self-interested agents operating in a social vacuum. In this paper we consider the implications for cooperative interactions
when prior social structures and corresponding social norms exist. In particular we investigate the influence of social rank/status
on perceptions of fairness and tolerance of cheating. We review evidence from a series of experiments employing the Wason
selection task (a test of conditional reasoning) and the ledger task (a decision making task) suggesting that people cued
to adopt a perspective of high social rank are more tolerant of cheating and simultaneously believe that they have been more
fairly treated (even when cheated) than people cued to adopt a perspective of low social rank. However, the evidence also
suggests interesting cross-cultural differences in perceptions of fairness and tolerance of cheating in ranked relationships.

Real Estate Returns: A Comparison with Other Investments 总被引:4,自引:1,他引:4
Real estate returns, measured unleveraged, have been between those of stocks and bonds over 1960–1982. Due to appraisal smoothing and imperfect marketability, one must be careful about directly comparing measured real estate returns with those on other assets. It is likely, however, that low correlations with stocks and bonds make real estate a diversification opportunity for traditional portfolio managers. In addition, the issue of how various assets are priced is addressed. While stocks are priced primarily on market or beta risk, and bonds are priced primarily on interest rate and default risk, the real estate pricing mechanism includes residual risk and non-risk factors such as taxes, marketability costs and information costs. 相似文献

This study uses a new data set to assess whether capital structure theory is portable across countries with different institutional structures. We analyze capital structure choices of firms in 10 developing countries, and provide evidence that these decisions are affected by the same variables as in developed countries. However, there are persistent differences across countries, indicating that specific country factors are at work. Our findings suggest that although some of the insights from modern finance theory are portable across countries, much remains to be done to understand the impact of different institutional features on capital structure choices. 相似文献
