Multi-level inventory management decisions with transportation cost consideration

In this article we address specific inventory management decisions with transportation cost consideration in a multi-level environment consisting of a supplier–warehouse–retailers. We develop two models – namely, decentralized ordering model and centralized ordering model to investigate the effect of collective ordering by retailers on the total inventory cost of the system. A numerical study shows that the proposed model is robust and generates reasonable cost savings. The models have potential in several multi-level applications such as fresh or frozen food delivery to stores of different supermarkets or the supply of medicine to a number of hospitals from a wholesaler.     

Uncertainty avoidance,risk tolerance and corporate takeover decisions

In this paper, we examine the role of national culture in corporate takeover decisions, by arguing that managerial risk tolerance (a combination of risk aversion and risk perception), at the national level, is a cultural trait and affects the expected net synergies CEOs require. We propose a theoretical framework that links CEO risk tolerance to the expected net synergies. We empirically show that CEOs of firms located in countries with lower levels of risk tolerance, measured by Hofstede’s (1980, 2001) uncertainty avoidance score, require higher premiums on takeovers, and show that uncertainty avoidance plays a greater role in relatively large takeovers. Additional testing reveals that CEOs from high uncertainty avoiding nations engage less in cross-border/cross-industry takeovers, suggesting that uncertainty avoidance captures more the CEO’s risk perception than his/her risk aversion.     

INSIDER TRADING,REGULATION, AND THE COMPONENTS OF THE BID–ASK SPREAD

In this article we investigate the relation between insider trading regulations and the bid–ask spread. We decompose the spread into its components before and after the enactment of strict new insider trading rules in New Zealand. We find that the enactment led to a significant decrease in the information asymmetry component of the spread, which is observed mainly in illiquid and high prechange information asymmetry companies. These findings are robust to model specification. In addition, we find a decrease in the contribution of information asymmetry to price volatility.     

Firm Heterogeneity,Contract Enforcement,and the Industry Dynamics of Offshoring*

We develop an endogenous growth model with R&D spillovers to study the long‐run consequences of offshoring with firm heterogeneity and incomplete contracts. In so doing, we model offshoring as the geographical fragmentation of a firm's production chain between a home upstream division and a foreign downstream division. While there is always a positive correlation between upstream bargaining weight and offshoring activities, there is an inverted U‐shaped relationship between these and growth. Whether offshoring with incomplete contracts also increases consumption depends on firm heterogeneity. As for welfare, whereas with complete contracts an R&D subsidy is enough to solve the inefficiency due to R&D spillovers, with incomplete contracts a production subsidy is also needed.     

Offshoring and product innovation

We propose an endogenous growth model with offshoring to investigate its effects on product innovation and growth in the country of origin. Offshoring is associated with reduced feedback from offshored plants to domestic labs as well as coordination problems between the offshored and domestic divisions of firms. Production and transport cost parameters affect the static decision to relocate plants but not R&D. Hence, offshoring may be chosen by firms when it damages the growth rate of their countries of origin. In particular, if offshoring reduces the feedback from plants to labs, it is likely to bring dynamic losses when the countries of origin are large, especially in sectors in which R&D is cheap and product differentiation is strong. It is also likely to slow growth in sectors in which contractual incompleteness gives a strong bargaining power to offshored divisions in intra-firm transactions.

Asymmetric Labor Markets, Southern Wages and the Location of Firms

This paper studies the behavior of firms towards weak protection of labor standards in developing countries (South). A less than perfectly elastic labor supply in the South gives firms an oligopsony position in the labor market tempting them to strategically reduce output to cut wages. In an open economy, competitors operating where labor standards are recognized meanwhile enjoy less aggressive competitors and raise output. Delocation also increases Southern wages and triggers a competition effect, lowering ex post output and hence potential profits of a relocating firm. These effects reduce relative profitability of moving production to the South casting doubts on traditional beliefs that multinationals are attracted to regions with lower wages. Moreover, adopting a minimum wage policy in the South eliminates the oligopsony distortion and improves competitiveness of Southern firms in the world product market. It also enhances consumer and wage surplus in the South and hence unambiguously raises Southern welfare.     

Analyzing Quality of Supply Chain Management in Hotels of Isfahan Using the Partial Least Squares (PLS)

ABSTRACT

Hotels, as one of the major tourism service providers, must offer high quality products to survive in this severely competitive environment so that they can preserve their competitive advantage dealing with other competitors. Therefore, considering the high importance of this subject, this study aims to analyze the quality of hotels supply chain in Isfahan- Iran. On this account, the literature of quality in supply chain is reviewed and seven factors affecting the supply chain are identified. Then research hypotheses are raised in accordance with the seven factors. Data was gathered using questionnaire and Partial Least Square was applied in order to analyze the data. The obtained results indicate that focus on customer, supply chain quality leadership, supply chain quality strategies, supply chain quality information and process approach results in an increase in supply chain quality; meanwhile, the two hypotheses regarding supplier quality management and human resources development of supply chain are rejected. The results of this article will be beneficial to hotels which want to increase the level of their service quality.     

Consumer Attitudes Toward Mandatory Traceability and Labeling Systems for Farmed Atlantic Salmon

The food incidence of polychlorinated biphenyls in farmed Atlantic salmon in Canada and its subsequent effects on the demand for farm-raised salmon has induced policymakers and stakeholders to develop new policies on food safety. This article analyzes consumer attitudes toward mandatory traceability and labeling systems for farmed Atlantic salmon in Newfoundland and Labrador. It identifies factors affecting consumers' decisions to purchase the product. Results show that consumers, on average, perceive the benefits of traceability and labeling systems on farm-raised Atlantic salmon in spite of its driving up the product price.     

Hotelling’s <Emphasis Type="Italic">T</Emphasis><Superscript>2</Superscript> control chart with two adaptive sample sizes

Some quality control schemes have been developed when several related quality characteristics are to be monitored. The familiar multivariate process monitoring and control procedure is the Hotelling’s T ² control chart for monitoring the mean vector of the process. It is a direct analog of the univariate shewhart [`(x)]{\bar{x}} chart. As in the case of univariate, the ARL improvements are very important particularly for small process shifts. In this paper, we study the T ² control chart with two-state adaptive sample size, when the shift in the process mean does not occur at the beginning but at some random time in the future. Further, the occurrence time of the shift is assumed to be exponentially distributed random variable.     

Customer Touchpoints im stationären Einzelhandel — Potenzial von Pervasive Computing

Je mehr individuelle Leistungen die Kunden verlangen, desto mehr Informationen ben?tigen die Anbieter. W?hrend die H?ndler im Distanzgesch?ft über personalisierte Daten ihrer Kunden und vor allem im Online-Shop über Bewegungsdaten verfügen, hat der station?re Einzelhandel noch erhebliche Datenlücken. Diese Lücken kann man mit einer Pervasive-Computing-Umgebung schlie?en. Neue Customer Touchpoints liefern Informationen darüber, wer bei ihm einkauft und wie der Einkauf durchgeführt wird.
