Inventory Model With Seasonal Demand: A Specific Application To Haute Couture, Byung Joon Park, Yih-Long Chang, Johnny C. Ho

Research Collection Lee Kong Chian School Of Business

In the stochastic multiperiod inventory problem, a vast majority of the literature deals with demand volume uncertainty. Other dimensions of uncertainty have generally been overlooked. In this paper, we develop a newsboy formulation for the aggregate multiperiod inventory problem intended for products of short sales season and without replenishments. A distinguishing characteristic of our formulation is that it takes a time dimension of demand uncertainty into account. The proposed model is particularly suitable for applications in haute couture, i.e., high fashion industry. The model determines the time of switching primary sales effort from one season to the next as well …

Removing The Shadow Of Suspicion: The Effects Of Apology Versus Denial For Repairing Competence- Versus Integrity-Based Trust Violations, Peter H. Kim, Donald L. Ferrin, Cecily D. Cooper, Kurt T. Dirks

Research Collection Lee Kong Chian School Of Business

Two studies were conducted to examine the implications of an apology versus a denial for repairing trust after an alleged violation. Results reveal that trust was repaired more successfully when mistrusted parties (a) apologized for violations concerning matters of competence but denied culpability for violations concerning matters of integrity, and (b) had apologized for violations when there was subsequent evidence of guilt but had denied culpability for violations when there was subsequent evidence of innocence. Supplementary analyses also revealed that the interactive effects of violation type and violation response on participants' trusting intentions were mediated by their trusting beliefs. Combined, …

Closed-Loop Supply Chain Models With Product Remanufacturing, R. Canan Savaskan, Shantanu Bhattacharya, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

The importance of remanufacturing used products into new ones has been widely recognized in the literature and in practice. In this paper, we address the problem of choosing the appropriate reverse channel structure for the collection of used products from customers. Specifically, we consider a manufacturer who has three options for collecting such products: (1) she can collect them herself directly from the customers, (2) she can provide suitable incentives to an existing retailer (who already has a distribution channel) to induce the collection, or (3) she can subcontract the collection activity to a third party. Based on our observations …

Embedded Co-Operation In The Context Of Singapore's Regionalization Program: The Batamindo Experiment Revisited, Caroline Yeoh, Adeline Kwan, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

The development of Singapore-styled industrial parks has resided on the country’s ability to negotiate investment concessions at inter-government level, to provide superior infrastructure, and where existing, through the links to influential business groups in the investment location. Singapore’s first transborder industrialization project in Batam (Indonesia) reflects this stratagem. This paper revisits the debate on the attractiveness of the low-cost investment enclaves for multinational investments, with insights from Batamindo Industrial Park. Through evidence from on-site interviews and case studies, this paper concludes that while the project’s progress to date has been largely overshadowed by socio-political uncertainties in the host environment, its …

Emotional Intelligence And Negotiation: The Tension Between Creating And Claiming Value, Maw Der Foo, Hillary Anger Elfenbein, Hwee Hoon Tan, Voon Chuan Aik

Research Collection Lee Kong Chian School Of Business

As a departure from past research on emotional intelligence (EI), which generally examines the influence of an individual's level of EI on that individual's consequences, we examined relationships between the emotional intelligence (EI) of both members of dyads involved in a negotiation in order to explain objective and subjective outcomes. As expected, individuals high in EI reported a more positive experience. However, surprisingly, such individuals also achieved significantly lower objective scores than their counterparts. By contrast, having a partner high in El predicted greater objective gain, and a more positive negotiating experience. Thus, high EI individuals appeared to benefit in …

Heuristics For A Brokering Set Packing Problem, Yunso Guo, Andrew Lim, Brian Rodrigues, Yi Zhu

Research Collection Lee Kong Chian School Of Business

In this paper we formulate the combinatorial auction brokering problem as a Set Packing Problem (SPP) and apply a simulated annealing heuristic to solve SPP. Experimental results are compared with a recent heuristic algorithm and also with the CPLEX Integer Programming solver where we found that the simulated annealing approach outperforms the previous heuristic method and CPLEX obtaining results within smaller timescales.

Challenges To Academic Marketing: Toward The Next Decade, David B. Montgomery

Research Collection Lee Kong Chian School Of Business

At the turn of the century and millennium, the Marketing Science Institute and the American Marketing Association undertook in a conference and a special issue of the Journal of Marketing to examine what were seen as fundamental issues and directions for marketing in the dawning millennium. A series of competitively commissioned papers addressed such questions as: How do customers and consumers really behave? How do markets function and evolve? How do firms relate to their markets? And what are the contributions of marketing to organizational performance and societal welfare? These questions were thought to best satisfy the criteria of differentiation, …

Social Trust, Cooperation, And Human Capital, Fali Huang

Research Collection School Of Economics

The importance of social trust on economic growth has been suggested by many empirical works. This paper formalizes the concept of social trust and studies its formation process in a game theoretic setting. It provides plausible explanations for a wide range of empirical and experimental findings. The main results of the paper are as follows. For utility-maximizing players, cooperation arises in one-period prisoner’s dilemmas if and only if there is social trust. The amount of social trust in a given game is determined by the distribution of players’ cooperative tendency. Cooperative tendency is in essence a component of human capital …

Operational Hedging: A Review With Discussion, Onur Boyabatli, L. Beril Toktay

Research Collection Lee Kong Chian School Of Business

Motivated by the increasing prevalence of operational hedging in corporate-level risk management programs, this paper provides an extensive overview and synthesis of the existing literature on operational hedging. In particular, we focus on the treatment of operational hedging in the operations management literature. We then explore how the concept of operational hedging is studied in the fields of finance, strategy and international business. Finally, we discuss and critique the approaches adopted in the operations management literature in the context of the broader literature on the topic.

From Dramaturgy To Theatre As Technology: The Case Of Corporate Theatre, Timothy Adrian Robert Clark, Iain Mangham

Research Collection Lee Kong Chian School Of Business

This article examines a piece of corporate theatre. Although theatre has entered organization studies through the dramatistic writing of Kenneth Burke and the dramaturgical writings of Erving Goffman, this article is concerned with an approach variously described as organizational, radical, situation or corporate theatre that treats theatre not primarily as a resource, an ontology or a metaphor but as a technology. This approach involves the deployment by an organization of dramatists, actors, directors, set designers, lighting specialists, and musicians to put on performances in front of audiences. Using frameworks derived from studies of theatre a particular piece of corporate theatre …

Metaheuristics With Local Search Techniques For Retail Shelf-Space Optimization, Andrew Lim, Brian Rodrigues, Xingwen Zhang

Research Collection Lee Kong Chian School Of Business

Efficient shelf-space allocation can provide retailers with a competitive edge. While there has been little study on this subject, there is great interest in improving product allocation in the retail industry. This paper examines a practicable linear allocation model for optimizing shelf-space allocation. It extends the model to address other requirements such as product groupings and nonlinear profit functions. Besides providing a network flow solution, we put forward a strategy that combines a strong local search with a metaheuristic approach to space allocation. This strategy is flexible and efficient, as it can address both linear and nonlinear problems of realistic …

Resource-Based Theory And Its Link To The Global Strategy, Structure And Performance Relationship: An Integrative Framework, Olivier Furrer, Jeffrey A. Krug, D. Sudharshan, Howard Thomas

Research Collection Lee Kong Chian School Of Business

The global strategy literature provides a basis for examining strategy, structure, and performance relationships in multinational firms. We develop a framework that examines these relationships and their linkages to the firm's intangible asset portfolio. Drawing on resource-based theory, this framework suggests that an on-going multinational firm's worldwide performance is dependent on the fit between its intangible asset portfolio, foreign market entry strategies, partner relationships, and worldwide organisational structure. Each of these dimensions can be linked back to the firm's worldwide strategy and the characteristics of its industry. Implications for research are discussed.

Privatizing Telecoms And Residual State Influence On Financial Performance, Burkhard N. Schrage, Paul M. Vaaler

Research Collection Lee Kong Chian School Of Business

We test competing theoretical perspectives explaining likely shareholder returns from material investment decisions announced by privatizing telecommunications firms (telecoms) with varying levels of residual state ownership. A principal-agent perspective suggests that decrease in residual state ownership in privatizing telecoms leads to more positive shareholder returns. Over time, this effect increases. An alternative credible privatization perspective suggests that retention of substantial (though not controlling) residual state ownership leads to more positive shareholder returns, but only in the short run. Over time this ownership effect fades quickly. We examine empirical support for these competing perspectives with an event study analyzing cumulative abnormal …

Expert Knowledge And The Role Of Consultants In An Emerging Knowledge-Based Economy, Hans-Dieter Evers, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

In the emerging globalised knowledge society/economy, a group of professionals, namely experts and consultants gain in importance. The paper discusses the following issues: Who are these experts and consultants? Why is this group of knowledge workers strategically important and why is their importance - socially in terms of number of persons and economically in terms of output or turnover - growing? How can we explain the increasing professionalisation of consultants? How do they gain their expertise and which role does academic knowledge play in professional attainment? How do consultants package and apply expert knowledge? What are the challenges experts and …

Procedural Priming Effects On Spontaneous Inference Formation, Kirmani Amma, Michelle P. Lee, Carolyn Yoon

Research Collection Lee Kong Chian School Of Business

Procedural priming refers to how the frequent or recent use of certain cognitive procedures on one task can lead to a greater propensity to use the same procedures on a subsequent task. In this paper, we demonstrate how procedural priming may be used to assess spontaneous inference formation in situations where the inference involves a relationship or rule. We do so in the context of the advertising cost–product quality rule, i.e., that higher advertising expense implies higher product quality. Prior research suggests that underlying the advertising cost–quality rule is a basic human attribution (the effort investment rule) that says, if …

Bias In The Correlated Uniqueness Model For Mtmm Data, James M. Conway, Filip Lievens, Steven E. Scullen, Charles E. Lance

Research Collection Lee Kong Chian School Of Business

This simulation investigates bias in trait factor loadings and intercorrelations when analyzing multitrait-multimethod (MTMM) data using the correlated uniqueness (CU) confirmatory factor analysis (CFA) model. A theoretical weakness of the CU model is the assumption of uncorrelated methods. However, previous simulation studies have shown little bias in trait estimates even when true method correlations are large. We hypothesized that there would be substantial bias when both method factor correlations and method factor loadings were large. We generated simulated sample data using population parameters based on our review of actual MTMM results. Results confirmed the prediction; substantial bias occurred in trait …

Price Rounding And Bid-Ask Spreads Before And After The Decimalization, Yan He, Chunchi Wu

Research Collection Lee Kong Chian School Of Business

We investigate price rounding before and after the pilot decimalization on the NYSE. We find that although rounding exists in transaction, bid, and ask prices in both the pre- and postdecimalization periods, it becomes less salient after the decimalization. The cross-sectional relationship between rounding and trading variables is similar before and after the decimalization, and so is the relationship between execution costs and rounding when trading variables are held constant. More importantly, the quoted and effective bid–ask spreads decrease after decimal trading, and this decrease can be ascribed to the decrease in rounding frequency after controlling for the changes in …

Parameter Selection In Genetic Algorithms, Onur Boyabatli, Ihsan Sabuncuoglu

Research Collection Lee Kong Chian School Of Business

In this study, we provide a new taxonomy of parameters of genetic algorithms (GA), structural and numerical parameters, and analyze the effect of numerical parameters on the performance of GA based simulation optimization applications with experimental design techniques. Appropriate levels of each parameter are proposed for a particular problem domain. Controversial to existing literature on GA, our computational results reveal that in the case of a dominant set of decision variable the crossover operator does not have a significant impact on the performance measures, whereas high mutation rates are more suitable for GA applications.

Modularity And The Product Lifecycle, Peter Cebon, Oscar Hauptman, Chander Shekhar

Research Collection Lee Kong Chian School Of Business

Product lifecycle theory, which underlies theories of technical innovation in economics, strategy, marketing, and operations management, is based implicitly on the assumption that products are integrated wholes. The modularization of products undermines the specific synergies which drive the product lifecycle, and this undermining has impacts spanning from the structure of individual organizations to the structure of economies and the definition of industries.

An Investigation Of Consumer Online Trust And Purchase-Repurchase Intentions, Dan J. Kim, Donald Ferrin, Raghav Rao

Research Collection Lee Kong Chian School Of Business

There is little research on trust and satisfaction in the electronic commerce from a longitudinal (pre- and postpurchase) perspective. Based on previous frameworks and theories, this study developed a combined model of consumer trust and satisfaction in the context of Internet shopping. From the valance framework and expectation-confirmation theory, several prepurchase and post-purchase factors such as risk, benefit, consumer trust, expectation, confirmation, and satisfaction are investigated as research variables affecting consumer repurchase intention.

The results of the study show that trust is the strongest predictor of the consumer’s purchase intention. In addition, as in traditional consumer satisfaction studies, it holds …

The Structure Of Affect: Reconsidering The Relationship Between Negative And Positive Affectivity, Russell Cropanzano, Howard M. Weiss, Jeff M. S. Hale, Jochen Reb

Research Collection Lee Kong Chian School Of Business

During the past decade organizational scientists have devoted considerable research attention to the topic of workplace affect. Despite important advances, continued progress depends on a better understanding of the structure of affective experience. The goal of this paper is to review progress to date. In particular, we review evidence pertaining to four constructs that have been widely used to organize research on affect: positive affectivity, negative affectivity, hedonic tone, and affect intensity. We review various structural models pertaining to these four constructs, devoting special attention to integrative frameworks and future research needs. Corresponding au

To Pester Or Leave Alone: Lifetime Value Maximization Through Optimal Communication Timing, Xavier Dreze, Andre Bonfrer

Research Collection Lee Kong Chian School Of Business

The marketing literature has long acknowledged the importance of a customer’s lifetime value in customer relationship management. More recently, researchers have turned their attention to the links between satisfaction and both customer acquisition and retention strategies. In this paper, we are interested in understanding the impact of communication frequency on customer retention and ultimately on lifetime value. We develop a theoretical framework for managing a customer database and addressing the tradeoffs between value extraction and customer retention. An empirical application of this framework is conducted for permission-based email marketing in the entertainment industry. This application recognizes the customization ability underlying …

The Demand And Supply-Side Impact Of The Kimberly-Clark, Scott Paper Products Merger In The Facial Tissues Category, Andre Bonfrer, Jagmohan S. Raju

Research Collection Lee Kong Chian School Of Business

We investigate how market behavior changed in the facial tissues category, following the 1995/1996 Kimberly-Clark merger with Scott Paper Products in the paper products industry. The facial tissues category is of interest because the US Department of Justice (DOJ), anticipating reduced competition after the merger, imposed a consent decree, requiring that Scotts’ facial tissues brands be licensed out to a third party. We utilize a two-stage budgeting demand system developed by Deaton and Muellbauer (1980a), coupled with general form supply-side first order conditions to compare demand and competitive behavior before and after the merger. Our findings indicate that the merger …
