A profit-maximization location-capacity model for designing a service system with risk of service interruptions

This paper considers the design of an immobile service system in which each facility’s service process is subject to the risk of interruptions. The location-capacity decisions and allocations are simultaneously made to maximize the difference between the service provider’s profit and the sum of customers’ transportation and waiting costs. An efficient Lagrangian-based solution algorithm is developed, which solves large-sized instances with up to 50 service facilities and 500 customers in a few seconds. Several sensitivity analyses and managerial insights are presented. The model is also applied to a case study on a logistics network design problem in the zinc mining industry.     

试论我国行业管理法的地位与体系

行业管理法是经济法体系中的一项法律，但是从宏观和微观的分类上行业管理法既不属于宏观经济调控法，也不属于微观的市场规制法，从其功能上来说行业管理法属于调整中观管理的经济法，行业管理法体系包含行业管理基本法、行业管理部门规章以及行业协会的自治规范等内容，具有指导思想和制度规范的立法，行业管理法对于促进行业领域的正常运行具有重要的意义。行业管理法与产业政策法规具有密切的关系，两者之间相辅相成，在国家的产业发展中共同发挥着指引和规范作用，研究行业管理法的地位和体系离不开产业政策法的分析介绍。笔者在本文中对行业管理法的地位和重要作用进行了分析，对行业管理法的体系内容也进行了详细的阐述，旨在通过本文的研究让更多人的认识到行业管理法，从而促进行业管理法作用的有效发挥。     

Impact of Shari’ah on Consumers’ Behavior Toward Sales Promotion Tools: Focus on Egyptian Convenience Products

This study measures to what extent compliance with Shari’ah moderates the relationship between different sales promotion tools—namely, price discount, product demonstration and sampling, buy one get one free (bonus pack), sweepstakes/lucky draws, scratch and win offers, and free samples—and three consumer behavioral responses (product trial, stockpiling, and spending more) for buying convenience products from supermarkets in Egypt. A total of 381 selected Muslim consumers/shoppers were surveyed via face-to-face interviews using a structured questionnaire. Overall correlation analysis between the six proposed sales promotion tools and consumers’ response behavior in general demonstrated a significant relationship. However, some specific tools did not indicate a significant relationship with specific response behaviors. Furthermore, correlation analysis initially indicated that there is a positive significant relationship between all sales promotion tools and compliance with Shari’ah, with the exception of sweepstakes and scratch and win offers, which demonstrated a significant negative relationship. Furthermore, after running linear stepwise regression, the model was fit (62%), indicating the moderating role of compliance with Shari’ah in the relationship between specific sales promotion tools—namely, sweepstakes/games and scratch and win offers—and Muslim consumers’ behavioral responses. Generally speaking, marketers should consider Shari’ah and ethical principles in Islam before creatively crafting promotional tools to attract Muslim consumers, and new tools could be developed with an Islamic orientation to attract Muslim consumers.     

How entrenched managers beat earnings expectations before and after SOX

This study investigates the relationship between managerial entrenchment and how firms meet or beat earnings forecasts. It further examines whether this relationship changes before and after the Sarbanes–Oxley Act (SOX). We find that, in the pre-SOX era, entrenched managers meet or exceed analyst forecasts more often than their unentrenched counterparts when analysts’ initial forecasts are high. This is mainly due to the drop in analysts’ consensus rather than earnings management. These results nearly disappear in the post-SOX era.

Inflation Triggers in Transition Economies: Their Evolution and Specific Features

Analysis of thirty inflation episodes in sixteen European transition economies, using the probit panel model with fixed effects, uncovers inflation triggers that overlap with those obtained in either developing or developed countries or both. However, we found some transition-specific features. Thus, the relative contribution of the triggers evolves as transition progresses, such that the early dominance of the output gap, the fiscal deficit, and elections are subsequently subdued by a rise in food and oil prices, the exchange rate regime, and the current account deficit. The last two triggers could be linked to deep financial integration in Europe and the consequent large flow of capital toward European transition economies in the 2000s, a phenomenon not observed in any other part of the world. In addition, the exchange rate regime as an inflation starter in transitional Europe may be due to its convergence with developed Europe and the resulting real appreciation of currency.
