This article reviews the international debate on statistical indicators. It describes historical backgrounds, as well as the present chaotic situation. It discusses what statistical indicators are and what they are for, as well as criteria for the choice of indicators, designed to monitor the achievement of economic, social, demographic, environmental and other goals set by United Nations conferences. Some suggestions for future work are made.  相似文献

We explore genetic and neurological bases for customer orientation (CO) and contrast them with sales orientation (SO). Study 1 is a field study that establishes that CO, but not SO, leads to greater opportunity recognition. Study 2 examines genetic bases for CO and finds that salespeople with CO are more likely to have the 7R variant of the DRD4 gene. This is consistent with basic research on dopamine receptor activity in the brain that underlies novelty seeking, the reward function, and risk taking. Study 3 examines the neural basis of CO and finds that salespeople with CO, but not SO, experience greater activation of their mirror neuron systems and neural processes associated with empathy. Managerial and research implications are discussed.  相似文献

The authors study how salespeople cope with social anxiety during customer contacts and find that two tactics, sale perseverance and task concentration, ultimately reduce dysfunctional protective actions. Both coping tactics, however, are differentially moderated by strength of felt physiological sensations and strength of negative expectations and thoughts. Salespeople experiencing anxiety cognitions should distract themselves by concentrating on their task to free up their thinking in relation to the task at hand. Engaging in behaviors to modify the situation by persevering on the sale, on the other hand, occupies action space and should be the coping strategy of choice for those salespeople confronting physiological sensations in relation to felt anxiety. Hypotheses are tested on a sample of 171 salespersons.

This paper estimates an Heterogeneous Agent Model (HAM) on currency trader indices to explain the large shifts in profitability in currency styles surrounding the global financial crisis. In the model, fund managers allocate capital conditional on recent performance to a value strategy, a momentum strategy, and a carry strategy. Subsequent estimation results reveal that (1) a large part of the behavior of currency managers can indeed be described by these three simple strategies, and (2) currency managers shift capital from recent winning styles to recent losing styles, and hence apply a negative feedback strategy. We finally show that a negative feedback strategy is indeed optimal, but currency managers could improve performance by applying it less aggressively if they were able to.  相似文献

The effect of risk on savings depends not just on preferences but also on the type of risk. This helps to explain why the empirical literature reports positive effects for developed countries but negative effects for developing countries.  相似文献

Factor models are often used to reduce the complexity of data. It is simple to find common factors and to interpret them. However, it is doubtful whether factor models are always appropriate. Especially when the common factor is considered to be an attitude, it must be stable through time and explain a considerable part of the variances. A procedure is suggested to test the usefulness of a common factor. In an experimental pilot study in which an attitude towards immigrant workers was investigated, the instability and superfluousness of a common factor is shown. An alternative model is presented which suggests that changing opinions can be explained by specific variables. Finally it is shown that a more stable common factor is found if a so-called MIMIC-design is used.  相似文献

Since measurement errors have strong effects in all relationships (statistical or otherwise) studied, there is an increasing interest in the data quality, which is the major justification for this research. This paper aims to present a new measurement procedure, the letter scale, which avoids many of the problems connected with the response modalities traditionally used in attitudinal research, especially the ordinal categorical scales. This paper analyzes the error composition of the scores obtained with this new measurement procedure. The validity of the procedure is also analyzed and the observed variance is assessed to determine which part of the observed variance is “valid”, which part is random error (attenuating relationships) and which is correlated error (magnifying relationships). Structural equation models will be used to provide estimates of the measurement quality: (i) Reliability, (ii) Construct validity, method effect and residual variance. In addition, this letter scale is evaluated under another different perspective, Information Theory measures are also used to assess the amount of information transmitted. The relative merits of this new measurement procedure as opposed to other common response modalities will be discussed in both cases.  相似文献

Event-history analysis is used to model the time dependency of two decisions: the decision to join a trade union, and the decision to leave a trade union. We formulate two hypotheses with regard to these two decisions and parametric regression models are used to investigate these hypotheses. The process of joining a trade union can be described by a decreasing rate, using a Weibull. For the process of leaving a trade union, we suggest an increasing rate that decreases after several years, a process best described by a log-logistic model.  相似文献
