A bi-objective model for planning and managing rail-truck intermodal transportation of hazardous materials

We propose a bi-objective optimization framework for routing rail-truck intermodal shipments with hazardous materials, when shippers and receivers have access to alternate intermodal terminals. A tabu-search based solution methodology is developed, which together with the optimization framework is applied to realistic size problem instances to gain managerial insights. Our analysis indicates that drayage accounts for a significant portion of transport risk and that it can be reduced by scheduling direct and faster trains; and, that the mix of intermodal trains depends on the interest of the decision-makers, where the resulting traffic can facilitate planning emergency response systems.     

The Effect of Graduated Response Anti‐Piracy Laws on Music Sales: Evidence from an Event Study in France

Despite the problem that filesharing poses to the creative industries, there is little research on the effectiveness of governmental anti‐piracy policies. This study analyzes how the HADOPI ² graduated response law in France affected digital music sales. Using a panel of sales data from the four major labels, we applied a difference‐in‐difference approach, comparing sales trends in France to a control group of European countries. We find that increased consumer awareness of HADOPI caused French iTunes music sales to increase by 22‐25%. The observed sales increase is larger in high piracy genres than low piracy ones, strengthening the causal interpretation of our results.     

The interrelationships between brand and channel choice

We propose a framework for the joint study of the consumer’s decision of where to buy and what to buy. The framework is rooted in utility theory where the utility is for a particular channel/brand combination. The framework contains firm actions, the consumer search process, the choice process, and consumer learning. We develop research questions within each of these areas. We then discuss methodological issues pertaining to the use of experimentation and econometrics. Our framework suggests that brand and channel choices are closely intertwined, and therefore studying them jointly will reveal a deeper understanding of consumer decision making in the modern marketing environment.     

The effect of presentation,product availability and ease upon transaction reliability for online food delivery aggregator applications – moderated mediated model

ABSTRACT

With advancements in mobile technologies, online food-delivery aggregators (OFA) have become an important distribution channel for restaurants. This study examines how the OFA applications affect diner’s cognitive and affective states and subsequent behavior by empirically testing a research model that incorporates antecedents of transaction reliability for restaurant order booking using a mobile application. Data collected from a survey of 458 respondents are analyzed using SEM. Drawing from SOR, CVT, and cue theory, the research established that product presentation and ease of use predict transaction reliability and are important mobile application attributes while choosing a particular OFA. The moderated mediation model extends the stimulus-organism-response framework and the consumer value theory. The findings demonstrate the moderating influence of gender, where the relationship is stronger for females. The study has a positivist approach with causalities satisfying the fundamental law of SOR theory. Higher media richness shall lead to a positive feeling about the product. A good presentation of the products on the mobile screen shall enhance the perception of product availability. The presence of abundant products makes it easy to search, thereby ease of searching the mobile screen. Mobile applications should be updated regularly to keep pace with the ever-changing mobile technologies.     

An investigation of skill requirements for business and data analytics positions: A content analysis of job advertisements

Presently, analytics degree programs exhibit a growing trend to meet a strong market demand. To explore the skill sets required for analytics positions, the authors examined a sample of online job postings related to professions such as business analyst (BA), business intelligence analyst (BIA), data analyst (DA), and data scientist (DS) using content analysis. They present a ranked list of relevant skills belonging to specific skills categories for the studied positions. Also, they conducted a pairwise comparison between DA and DS as well as BA and BIA. Overall, the authors observed that decision making, organization, communication, and structured data management are key to all job categories. The analysis shows that technical skills like statistics and programming skills are in most demand for DAs. The analysis is useful for creating clear definitions with respect to required skills for job categories in the business and data analytics domain and for designing course curricula for this domain.     

Change in Consumer Patronage and Willingness to Pay at Different Levels of Service Attributes in Restaurants: A Study in India

Consumer patronage and consumer willingness to pay are the two most important criteria for business development. The current study investigates the changing preferences of consumers in a developing economy with respect to three major service attributes from the restaurant industry: food quality, service, and ambiance. Results indicated that consumers give greater preference to quality over service in high-end restaurants and prefer service compared with ambiance in quick-service restaurants. Food quality was found to have strong interaction effect with two other variables. When food quality was improved from low to high, consumer preferences for ambiance and service tended to change accordingly in the same direction, but not necessarily at the same level. Thus, restaurateurs have a strategic advantage when they choose high quality food and an appropriate level of service or ambiance. Consumer expectations are significantly different for high-end, full-service restaurants and quick-service restaurants in service attributes.     

The impact of individual and institutional investor sentiment on the market price of risk

We examine the effect of individual and institutional investor sentiment on the market price of risk derived from DJIA and S&P500 index returns. Consistent with behavioral asset pricing models, we find significant positive response of rational sentiment suggesting greater incentive for rational investors to engage in arbitrage when the compensation for taking risk is greater. Further, an increase in irrational optimism leads to a significant downward movement, but an increase in rational sentiment does not lead to a significant change market price of risk. These results are robust for both market indexes, DJIA and S&P500 and for both individual and institutional investor sentiment.     

Drop-the-loser design in the presence of covariates

In the present work we develop a randomized two-treatment adaptive allocation design with covariates ensuring smaller variability of treatment allocations. We study, both numerically and theoretically, several exact and limiting properties of the design and consider an inferential problem following the allocation design. We compare the design with some of the existing allocation designs by computing its various performance measures.     

Anger Strays,Fear Refrains: The Differential Effect of Negative Emotions on Consumers’ Ethical Judgments

Although various factors have been studied for their influence on consumers’ ethical judgments, the role of incidental emotions has received relatively less attention. Recent research in consumer behavior has focused on studying the effect of specific incidental emotions on various aspects of consumer decision making. This paper investigates the effect of two negative, incidental emotional states of anger and fear on ethical judgment in a consumer context using a passive unethical behavior scenario (i.e., too much change received). The paper presents two experimental studies. Study 1 focuses on the interaction of moral intensity (amount of change) and incidental emotion state in predicting the ethical judgment while study 2 investigates the underlying causal mechanism behind the process, using a mediation analysis. The results reveal a significant interaction between moral intensity and incidental emotion. Specifically, individuals in the state of incidental fear exhibit higher levels of ethical judgment as the moral intensity increases as compared to individuals in the state of incidental anger. Further, perceived control is found to mediate the relationship between emotional state and ethical judgment under higher moral intensity condition.     

Ethical Leadership,Organic Organizational Cultures and Corporate Social Responsibility: An Empirical Study in Social Enterprises

While recent studies have increasingly suggested leadership as a major precursor to corporate social responsibility (CSR), empirical studies that examine the impact of various leader aspects such as style and ethics on CSR and unravel the mechanism through which leadership exerts its influence on CSR are scant. Ironically, paucity of research on this theme is more prevalent in the sphere of social enterprises where it is of utmost importance. With the aim of addressing these gaps, this research empirically examines the interaction between ethical leadership and CSR and, in addition, investigates organic organizational cultures (clan culture and adhocracy culture) as mediators in the above interaction. To this end, a model was developed and tested on the sample of 350 middle- and top-level managers associated with 28 Indian healthcare social enterprises, using Structural Equation Modeling Analysis, Bootstrapping and PROCESS. Results reveal that ethical leadership both directly and indirectly influences CSR practices. The indirect influence of ethical leadership involves nurturing clan and adhocracy cultures, which in turn influence CSR. These findings are significant for social enterprise leaders seeking to encourage their organizations’ socially responsible behavior.
