The main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments.
We test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice
experiment to report their experienced certainty when going through the choice tasks. In a split-sample test, we show that
follow-up choice certainty questions are procedural invariant. The self-reported certainty results indicate that learning
occurs, but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates
or variance across choice tasks. Additional tests of choice consistency suggest that preferences in the choice experiment
are stable and coherent. 相似文献

The standard formal presentation of the Dixit‐Stiglitz‐Krugman (DSK) model of monopolistic competition with a constant‐elasticity‐of‐substitution (CES) utility function supposes a sufficient number of firms so that the elasticity of demand facing each variety is approximated by a constant elasticity of substitution. Such a formulation forces economies of scale to be frozen so that firm size never changes. We use a Bertrand‐Nash interpretation of the equilibrium that allows the elasticity of demand facing each variety to depend on the number of varieties, thus allowing the gains from globalization to reflect both the increase in variety and the exploitation of economies of scale. We also develop a precise expression for per capita real income with any number of sectors and examine the age‐old question of the socially optimal number of varieties. 相似文献

Both statistical appraisal and hedonic pricing models decompose houses into a set of individual characteristics. Regression estimates yield the contribution of each characteristic to total value. Unfortunately, straightforward application of OLS may produce untenable results such as implausible coefficient magnitudes or incorrect signs. Often the suspected cause is multicollinearity. This article examines the effect on estimation efficiency of differing levels of multicollinearity, R2, and a priori information in the form of sub-market cost data, by comparing inequality restricted least squares (IRLS) with OLS in a series of Monte Carlo experiments. The IRLS procedure investigated here hybridizes the statistical market approach implemented by OLS, and the more traditional cost approach. The experiments show dramatic gains in estimation efficiency from exploiting a priori information through IRLS. 相似文献

A study of personal values held by Japanese and foreign students, trainees and managers showed recent Japanese trainees slightly more conservative than their 1979 cohorts. Foreign students and foreign managers held more pro-American work values than either Japanese managers or trainees. Finally, for the Japanese respondents, there was some evidence of specific shifts away from the Japanese employment system in the areas of thenenko compensation and promotion systems in their organisations.Roy J.

We present a faster, more accurate technique for estimating implied volatility using the standard partial derivatives of the Black‐Scholes option‐pricing formula. Beside Newton‐Raphson and slower approximation methods, this technique is the first to provide an error tolerance, which is essential for practical application. All existing noniterative approximation methods do not provide error tolerances and have the potential for large errors. 相似文献

As the example presented demonatrate, the analysis of cross-impactss amount a group of related events is somewhat more complex than perhaps heretofore imagined. Impacts of effects between such events very often carely depend on their temporal sequence. The event outcome space is accordingly multiplied considerably over the case where such dependency is ignored. The result is that high premium is placed on methods that seek to reduce analytical complexity without distorting essential event intrications. 相似文献

Competitive negotiators frequently use tactics which others view as "unethical", in that these tactics either violate standards of truth telling or violate the perceived rules of negotiation. This paper sought to determine how business students viewed a number of marginally ethical negotiating tactics, and to determine the underlying factor structure of these tactics. The factor analysis of these tactics revealed five clear factors which were highly similar across the two samples, and which parallel (to a moderate degree) categories of tactics proposed by earlier theory. Data from one sample also permitted comparisons of the appropriateness of certain tactics across gender, nationality, ethnic origin and perception of one's negotiating style. 相似文献

As restaurants are the primary hospitality business represented on flash-sale sites, this study examined motivations of restaurant managers when choosing whether to utilize the promotional mediums of flash-sales. Interviews were administered as a measurement instrument. Results demonstrated restaurants which have employed flash-sales are weary of the likelihood of success and believe the flash-sales brought in established customers. Non-users indicated hesitation towards adoption of flash-sales related to low profit margins per item in their operation and the percentage split of the sale price between the firm and flash-sale provider. Findings provide keen foundational insight into the flashsale phenomenon. 相似文献
