Traditional real options models demonstrate the importance of the “option to wait” due to uncertainty over future shocks to project cash flows. However, there is often another important source of uncertainty: uncertainty over the permanence of past shocks. Adding Bayesian uncertainty over the permanence of past shocks augments the traditional option to wait with an additional “option to learn.” The implied investment behavior differs significantly from that in standard models. For example, investment may occur at a time of stable or decreasing cash flows, respond sluggishly to cash flow shocks, and depend on the timing of project cash flows. 相似文献

Using in-depth interviews of the CEO/Presidents of 21 small manufacturing firms, this research explored how leaders with a high market-oriented cognitive model have intentionally pursued the implementation of that model and how their activities differed from leaders with a low market-oriented cognitive model. Results indicated that leaders in high market-oriented organizations appeared to be working from cognitive models that reflected market-oriented values, and norms consistent with those suggested by Homburg and Pflesser. Additionally, results indicated strong consistencies across firms in the mechanisms used by leaders to implement their high market-oriented cognitive models and different but equally strong consistencies in the mechanisms used by leaders to implement their low market-oriented cognitive models. Structurally, high market-oriented leaders expressed less departmentalization than low market-oriented firms, used some form of internal customer/supplier networks, had very open communication systems, and established performance management systems designed to initiate and reward market-oriented behaviors among employees. 相似文献

The ability of developing countries to cope with emerging standards in food and agricultural products is influenced by their institutional capacity. This paper develops original measures of four dimensions of standards-related, institutional capacity: information, conformity, enforcement, and international standard-setting. These measures are incorporated into a gravity model to investigate whether these capacities offset the negative effects of Aflatoxin B1 standards on food and agricultural product trade. The results indicate that informational capacity and conformity capacity do indeed have such offsetting effects. The evidence with regard to enforcement and international standard-setting is less clear. 相似文献

Some of the major theoretical approaches to the study of the work-leisure relationship are examined. Theoretical conceptualization is confronted with empirical findings and some avenues for further research are suggested. The first section maps some of the major approaches taken in the study of the work-leisure relationship in the social science literature. The second section focuses on the central issue in the debate on the work-leisure relationship, namely, the effects of the structure (content) of work and work-related attitudes on leisure behaviour and leisure-related attitudes. The third section examines empirical evidence collected by social scientists studying the work-leisure relationship. The fourth section attempts to answer the question of why social science research on the work-leisure relationship has produced, thus far, few conclusive and statistically significant findings. The final section summarizes the discussion and suggests certain research strategies for future sociological and socio-psychological studies of the work-leisure relationship. 相似文献
