An experimental setting was formulated where individuals processed financial information and provided estimates of changes in security prices. The ability of subjects to express accurate subjective cue weights was assessed by comparing the subjective weights with objective (statistical) cue weights based on their judgments. The results indicate an encouraging degree of insight, especially when the results are compared with previous studies in psychology, since this group of users of accounting information were able to express indications of relative cue importance which reflected the way they were using the information.  相似文献

This paper describes a multiple competing technologies market penetration model which incorporates multiple attributes rather than strictly price into the (static) market share allocation function. Application of the first-generation version (linear and deterministic) of this model in a DOE budget preparation exercise, model parametrics, and results are described. Results are most sensitive to (1) moderate shifts in commercialization date, (2) small changes in market growth rates (for technological penetrating expansion markets only), and (3) shifts in static market share curve coefficients. The assessment process, it is noted, depends upon cooperative support; it is vulnerable to any intentionally disruptive activities.  相似文献

We study price transmission processes within EU pork marketsafter the implementation of the EU single market in 1993. Wecompare results derived from non-parametric regressions withthose obtained using alternative non-linear threshold models.Both techniques support the hypothesis that prices are transmittedacross spatially separate EU pig markets and provide evidencefor asymmetric price adjustments. They also suggest the existenceof a range of price differentials where equilibrating priceadjustments are less intense. Non-parametric techniques oftensuggest a higher degree of price transmission than that impliedby threshold models.  相似文献

The 11 genebanks of the Consultative Group on International Agriculture (CGIAR) have grown considerably in size over the past few decades, currently holding about 666,000 accessions of germplasm. Conserving germplasm is a very long run, if not in perpetuity, proposition. The mismatch between the mainly annual funding support for this conservation effort and its very long‐term nature and intent is a serious concern. Using the results of five CGIAR genebank case studies (accounting for 87% of the total CGIAR genebank holdings), we estimate the size of an endowment or trust fund that would be required to assure a funding stream to conserve this genetic material for future generations. The annual cost (in year 2000 US$) of conserving and distributing the genetic material presently held in all 11 CGIAR genebanks is estimated to be 5.7 million US$ (mUS$), which could be maintained for all future generations by setting aside a fund of 149 mUS$ (invested at a real rate of interest of 4% per annum). This would be sufficient to underwrite the costs for the CGIAR's current conservation activities in perpetuity (estimated to be 61 mUS$), as well as the cost of maintaining the distribution activities (88 mUS$) that provide germplasm to breeders, scientists, farmers and others world wide.  相似文献

Our research not only addresses the strategic purposes of expatriate assignments within multinational corporations but, unlike most earlier studies, extends the investigation to include their path-dependent outcomes. Adopting a knowledge transfer perspective we first re-define the principal assignment purpose categories of Edström and Galbraith (1977a Edström A Galbraith JR 1977a Transfer of Managers as a Control and Coordination Strategy in Multinational Organizations Administrative Science Quarterly 22 June 11 22 [Crossref] [Google Scholar]) as business applications, organization applications and expatriate learning. These purpose categories are then conceptually related in terms of a four-part typological matrix based on individual-level knowledge-flow direction and role focus. Following a review of prior assignment purpose studies we posit that strategic expatriate assignment purposes should be considered not in isolation but relative to their potential outcomes. Adopting a single-case research design with multi-method data collection, we demonstrate the emergent nature of strategic assignment outcomes. It is shown for our transnational case organization that knowledge acquisition or learning by expatriates is an underestimated strategic assignment outcome, more so than either business or organization-related knowledge applications.  相似文献
