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.     

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.

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.
