overview of OR techniques for airline revenue management

With the increasing interest in decision support systems and the continuous advance of computer science, revenue management is a discipline which has received a great deal of interest in recent years. Although revenue management has seen many new applications throughout the years, the main focus of research continues to be the airline industry. Ever since LITTLEWOOD (1972) first proposed a solution method for the airline revenue management problem, a variety of solution methods have been introduced. In this paper we give an overview of the solution methods presented throughout the literature.     

Corporate financing and anticipated credit rating changes

Firm circumstances change but rating agencies may not make timely revisions to their ratings, thereby increasing information asymmetry between firms and the market. We examine whether firms time the securities market before a credit rating agency publicly reveals its decision to change a firm’s credit rating. Using quarterly data, we show that firms adjust their financing structures before credit rating downgrades are publicly revealed. Specifically, firms on average increase their debt financing by 1.29 % before the disclosure of a rating downgrade, and this increase is due to the issuance of debt rather than the repurchase of equity. In contrast, firms do not take significant financing actions before credit rating upgrades.     

Productivity and impact in advertising research since the millennium: a profiling and investigation of drivers of impact

What does it take to become a top advertising scholar in productivity? What drives impact in advertising research? This article sets out to answer these two questions by assessing the productivity and impact among scholars and their work in advertising since the millennium. As a two-part study, we begin by benchmarking and profiling the top 1% scholars in the field based on their research publications in the three top advertising journals (Journal of Advertising, Journal of Advertising Research, and International Journal of Advertising). Next, we employ a three-perspective conceptual model to identify the salient drivers of impact in advertising research. By content analyzing 1443 articles in the three journals published between 2000 and 2014, we show that certain universalistic and particularistic factors (to a lesser extent) significantly predict paper citations. Our findings reveal how advertising academia is advancing and showing signs of internationalization in the new millennium, which provides implications for the field's advancement and scholarship.     

Corporate environments and international transfer pricing: an empirical study of China in a developing economy framework

This paper investigates the international transfer pricing methods adopted by multinational corporations (MNCs) in China and how their choices are affected by their specific corporate attributes in the context of the business environment in China. Empirical test results based on structured interviews indicate that MNCs having a local (Chinese) partner in management tend to adopt market-based transfer pricing methods. The influence of local partners on the choice of transfer pricing methods is modified by the impact of the source of foreign investment, as the analysis reveals that US-sourced MNCs are more likely to use cost-based pricing methods for international transfers. The influences of these two variables on the choice of transfer pricing methods are significant both directly and interactively. There is also some evidence that export-oriented enterprises are more likely to adopt cost-based transfer pricing than those aiming at China's domestic market. By providing empirical evidence on the impact of key corporate attributes on transfer pricing which have not been studied by prior research in the context of a developing economy, this research contributes to a more comprehensive understanding of transfer pricing in developing countries.     

Manager's occupational stress in state-owned and private enterprises in the People's Republic of China

Privatization that has taken place in the People's Republic of China has brought about improved profitability and effectiveness of enterprises. However, it is not known whether employees' occupational stressors and strains in private enterprises would differ from those in state-owned enterprises. This study aims to examine the major sources of manager's occupational stress in private and state-owned enterprises, and comparing the intensity of these stressors and strains. The relationships between stressors and strains were also investigated in both economic sectors. The questionnaires were completed by 234 managers in state-owned enterprises and 179 managers in private enterprises from eight cities of the PRC. The questionnaires were used to measure sources of stress, job satisfaction, and physical and psychological strain. The results showed that managers in private enterprises experienced higher levels of occupational stressors (mainly ‘Organizational structure and climate’ and ‘Relationship with others’) and psychological strains than those in state-owned enterprises. Moreover, ‘Organizational structure and climate’ was also found to be a major stressor when predicting both psychological and physical strain in both economic sectors.     

Effects of family structure and socialization on materialism: a life course study in Thailand

Consumer researchers have long been interested in understanding the development of materialistic attitudes and values in different cultural settings. The life course approach, which has developed recently as an interdisciplinary programme for studying various aspects of behaviour, was used as an overarching framework for studying the development of materialism in Thailand. Specifically, the paper first presents the general conceptual framework that serves as a blueprint for discussing theoretical perspectives. Next, hypotheses derived from life course perspectives are formulated, and a survey of young adults (ages 20 to 32) is used to test them. We found that family disruption influences materialism only among those young adults from lower social classes. Findings of this paper have implications for theory development and suggest directions for future research.     

Spontaneous vs. policy-driven: The origin and evolution of the biotechnology cluster

The biotechnology industry is at the heart of the fast-growing knowledge-based economy. One of the distinguishing characteristics of this industry is clustering. A cluster, like an organism, experiences origin, growth, and decline/reorientation. Our study constructs a framework to analyze biotechnology clusters with different origins, “spontaneous” and “policy-driven”, through their life cycles. We use the Bay Area in the United States and Shanghai Zhangjiang Hi-Tech Park in China as two cases to represent spontaneous and policy-driven biotechnology clusters. This study fills the gap in the literature by comparing these two types of biotechnology clusters in an evolutionary perspective. The key success factors of both biotechnology clusters are their own human and financial capital, but they differ in their underlying processes for creating and sharing these resources. The most fundamental differences arise from the impact of entrepreneurship, social capital and network patterns on the cluster's configuration.
