Modeling the day-of-the-week shopping activity and travel patterns   总被引:1,自引:0,他引:1  
Dae-Sic Yun  M.E. O'Kelly 《Socio》1997,31(4):307-319
This research develops models that extend existing multi-day analyses of shopping activity patterns. The main hypothesis is that shopping activity choice behavior varies, depending on the day of the week. Using a nested logit model structure, this hypothesis is tested by developing models of daily activity choice behavior for each day of the week. In doing so, household activity choice behavior is represented by three stages, with a shopping activity participation decision as the highest stage, the scheduling decision as the next lower stage, and the number of shopping stops as the lowest stage. Empirical results confirm the nested logit model structure hypothesized in this study. Furthermore, it is found that major distinctions in the daily utility functions take place between the weekday and weekend models. However, differences among weekday models are also observed. This indicates that there appear to be behavioral differences even among weekdays although households are exposed to the same set of temporal constraints.  相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment.  相似文献

This article presents findings from a study of control operators that raise concerns about safety-critical knowledge, culture and training. It is argued that the adoption of automated control systems can hinder the transfer of knowledge amongst operators, and this becomes an increasingly serious hazard as tacit knowledge is lost because of employee turnover.  相似文献

Hall and Miles (1990) suggest an approach of estimating default probabilities of banks using stock market information, and in this paper we apply an aggregated version of their approach to banking sectors around the world in both developed and emerging economies. We study the market’s assessment of the probability of systemic banking crises world wide over the last decade, including the Asian crisis 1997–1998. In addition, we investigate whether there is a relationship between the failure probability and institutional features of the actual banking sector. The quality of governance and the degree of law and order in a country is found to be significantly negatively related to the market based failure probabilities as is an explicit deposit insurance during periods of crisis.  相似文献

The aim of this paper is to trace and explain variations in calculative and collaborative human resource management (HRM) practices between companies and across national borders. Variations and similarities are explained in terms of the convergence and divergence of HRM practices determined by national institutions, and the increasing influence of multinational companies (MNCs). We explore the diffusion of HRM practices in Europe over time, using data sets from two surveys conducted in several European countries in 1995 and 2000. We use institutional explanations for the development of three selected bundles of HRM practices: individual, calculative performance‐oriented practices; collective incentive schemes for the alignment of interests; and collaborative practices that seek to enhance the commitment of employees. We found substantial effects of country‐specific institutions and of the country of origin of MNCs, which clearly support the institutional duality thesis. Foreign‐owned MNCs, especially those that are US‐based, appear to moderate country‐specific institutional effects on the diffusion of the three HRM bundles.  相似文献

Cash settlement of derivative contracts makes them susceptible to manipulation by traders who expect to close large positions upon final settlement. Cash settlement also increases underlying volatility when hedgers unwind their hedges if they have no incentives to control their trading costs. Limits on the positions that traders can carry into final settlement can be used to mitigate associated economic inefficiencies when surveillance is insufficient. This article develops a model that regulators can use to set these limits that is based upon microstructure theory. The empirical findings indicate that existing position limits are largely inconsistent with those suggested by the model. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:945–965, 2005  相似文献

Theoretical considerations for a meaningful code of professional ethics   总被引:1,自引:1,他引:0  
The professions have focused considerable attention on developing codes of conduct. Despite their efforts there is considerable controversy regarding the propriety of professional codes of ethics. Many provisions of professional codes seem to exacerbate disputes between the profession and the public rather than providing a framework that satisfies the public's desire for moral behavior.After examining three professional codes, we divide the provisions of professional codes into those provisions which urge professionals to avoid moral hazard, maintain professional courtesy and serve the public interest. We note that whereas provisions urging the avoidance of moral hazard are uncontroversial, the public is suspicious of provisions protecting professional courtesy. Public interest provisions are controversial when the public and the profession disagree as to what is in the public interest. Based on these observations, we conclude with recommendations regarding the content of professional codes.Karim Jamal is an Associate Professor in the Department of Accounting at the University of Alberta. His research interests are in modelling judgment processes of individuals in professional firms and financial markets. He is currently involved in research on the auditor-client negotiation process, the role of framing effects in masking fraud as well as the means by which frauds are detected, and tensions in professional codes of conduct especially between confidentiality and public disclosure.Norman E. Bowie is the Elmer L. Andersen Chair in Corporate Responsibility at the University of Minnesota. He is the co-editor ofEthical Theory and Business and has published numerous books and articles in business ethics and political philosophy. His most recent book isUniversity Business Partnerships: An Assessment.  相似文献
