Corporate Social Responsibility Reputation Effects On Mba Job Choice: Controlling For Region Of Origin, David B. Montgomery, Catherine A. Ramus Oct 2003

Corporate Social Responsibility Reputation Effects On Mba Job Choice: Controlling For Region Of Origin, David B. Montgomery, Catherine A. Ramus

Research Collection Lee Kong Chian School Of Business

In a preliminary study with 279 MBA’s from two European and three North American business schools we find that reputation-related attributes of caring about employees, environmental sustainability, community/stakeholder relations, and ethical products and services are important in job choice decisions. We use an adaptive conjoint analysis survey tool to discover the relative weighting of a new set of social responsibility job search criteria, including these attributes with traditional job search criteria like financial package, geographical location, etc. In addition, our results show that more than ninety percent of the MBAs in the sample were willing to forgo financial benefits in …

The Enhancement Bias In Consumer Decisions To Adopt And Utilize Product Innovations, Shenghui Zhao, Robert J. Meyer, Jin K. Han Oct 2003

The Enhancement Bias In Consumer Decisions To Adopt And Utilize Product Innovations, Shenghui Zhao, Robert J. Meyer, Jin K. Han

Research Collection Lee Kong Chian School Of Business

The ability of consumers to anticipate the value they will draw from new product generations that expand the capabilities of incumbent goods is explored. Drawing on previous research in affective forecasting, the work explores a hypothesis that consumers will frequently overestimate the benefits they envision drawing from new added product features and underestimate the learning costs required to realize those benefits. This hypothesis is tested using a computer simulation in which subjects are trained to play a Pacman-like arcade game where icons are moved over a screen by different forms of tactile controls. Respondents are then given the option to …

Store Brands: Who Buys Them And What Happens To Retail Prices When They Are Introduced?, Andre Bonfrer, Pradeep K. Chintagunta Oct 2003

Store Brands: Who Buys Them And What Happens To Retail Prices When They Are Introduced?, Andre Bonfrer, Pradeep K. Chintagunta

Research Collection Lee Kong Chian School Of Business

In this paper we study store brand demand behavior by examining a panel of household level and store-level data in five stores located in a competing market area. We seek to address three fundamental questions from this data. First, is there a link between store loyalty and brand loyalty? Second, does store loyalty raise store brand choice probabilities? Third, if a store brand is introduced into a category, what happens to the retail prices of the incumbent brands in the category? We find that store loyalty is negatively associated with brand loyalty, and that store loyalty increases the likelihood of …

A Renewable-Resource Approach To Database Valuation, Xavier Dreze, Andre Bonfrer Oct 2003

A Renewable-Resource Approach To Database Valuation, Xavier Dreze, Andre Bonfrer

Research Collection Lee Kong Chian School Of Business

We demonstrate in this paper that firms should view customers in a database as a renewable resource when valuating them. Indeed, customer names flow in and out of the firm’s databases, and the goal of the firm is to optimize the overall customer acquisition/cultivation/attrition process. The renewable resource approach to the problem of maximizing the profits generated by a flow of customer names is more appropriate than the traditional Customer Lifetime Value (CLV) approach. We show that CLV underestimates the true value of names (by more than 400% in some cases) and leads to sub-optimal customer relationship management and acquisition …

A Note On The Numerical Solution Of High-Order Differential Equations, Y. Wang, Yibao Zhao, G. W. Wei Oct 2003

A Note On The Numerical Solution Of High-Order Differential Equations, Y. Wang, Yibao Zhao, G. W. Wei

Research Collection Lee Kong Chian School Of Business

Numerical solution of high-order differential equations with multi-boundary conditions is discussed in this paper. Motivated by the discrete singular convolution algorithm, the use of fictitious points as additional unknowns is proposed in the implementation of locally supported Lagrange polynomials. The proposed method can be regarded as a local adaptive differential quadrature method. Two examples, an eigenvalue problem and a boundary-value problem, which are governed by a sixth-order differential equation and an eighth-order differential equation, respectively, are employed to illustrate the proposed method.

The Effects Of Sexual Orientation On Hirability Ratings: An Experimental Study, Greet Van Hoye, Filip Lievens Sep 2003

The Effects Of Sexual Orientation On Hirability Ratings: An Experimental Study, Greet Van Hoye, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Despite its rising importance, empirical research about sexual orientation in the workplace is still scarce. This experimental study examined if gay candidates, with the same work-related qualities as heterosexual candidates, would be judged less favorably in a personnel selection context. Written candidate profiles were varied in a 3 x 3 between-subjects factorial design, with candidate quality and sexual orientation as experimental variables. Our results indicated that the hirability ratings of 135 selection professionals were based on candidate quality and that no discrimination on the basis of sexual orientation occurred. Implications of these findings and directions for future research are discussed.

Capacitated Network Revenue Management Through Shadow Pricing, Mustapha Bouhtou, Madiagne Diallo, Laura Wynter Sep 2003

Capacitated Network Revenue Management Through Shadow Pricing, Mustapha Bouhtou, Madiagne Diallo, Laura Wynter

Research Collection School Of Computing and Information Systems

In this paper, we analyze a method that links Lagrange multipliers from a resource allocation problem to the problem of revenue or profit maximization. This technique, first proposed in the transportation science literature by [7] has important implications for telecommunication network pricing. Indeed, the framework provides a generalization of telecommunication resource allocation/shadow price-based schemes such as those of [6] and [9], in that it permits the optimization of the shadow prices themselves, through a computationally simple procedure. We analyze the extent to which revenue can be maximized on a network that uses shadow-price-based prices, and how to deal with cases …

In Praise Of The Strange Virtue Of People-Smuggling, Chandran Kukathas Sep 2003

In Praise Of The Strange Virtue Of People-Smuggling, Chandran Kukathas

Research Collection School of Social Sciences

Almost everyone is against people-smuggling. The refugee advocate excoriating the government for its mistreatment of asylum seekers, no less than the departmental official bemoaning the numbers of boat people landing on Australian shores, feels well-justified in insisting that, somehow, something must be done to put an end to this 'evil trade'. On the scale of virtue, the people smuggler appears barely a notch above (and for many, several notches below) the drug dealer, the child molester, or the gangster.

E-Ducation, J. Erickson, Keng Siau

Research Collection School Of Computing and Information Systems

Most educators are convinced Internet technology will sharply alter the educational landscape of the future, but considerable uncertainly still exists as to exactly how the classroom will evolve over the next decade. Many of the relevant technologies in development are a direct result of the Internet2 Project [1], a collaboration of more than 200 universities working closely with private industry and the National Science Foundation to build and promote an advanced network using state-of-the-art technology and applications. But how the classroom evolves depends not only on advanced Internet2 technologies, which are discussed later in the article, but also on issues …

Aggregated Causal Maps: An Approach To Elicit And Aggregate The Knowledge Of Multiple Experts, S. Nadkarni, Fiona Fui-Hoon Nah Sep 2003

Aggregated Causal Maps: An Approach To Elicit And Aggregate The Knowledge Of Multiple Experts, S. Nadkarni, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

This paper presents a systematic procedure to elicit and aggregate the knowledge of multiple individual experts and represent it in the form of an Aggregated Causal Map (ACM). This procedure differs from existing methods in two ways. First, unlike other methods, this method does not rely on group interaction in eliciting knowledge of multiple experts, and, therefore, is not fraught with biases associated with group dynamics. Second, this method uses both the idiographic and nomothetic approaches while existing methods focus on nomothetic approaches to knowledge elicitation. We draw on the strengths of both approaches by using the idiographic approach to …

What To Do On Spring Break? The Role Of Predicted, On-Line, And Remembered Experience In Future Choice, Derrick Wirtz, Justin Kruger, Christie N. Scollon, Ed Diener Sep 2003

What To Do On Spring Break? The Role Of Predicted, On-Line, And Remembered Experience In Future Choice, Derrick Wirtz, Justin Kruger, Christie N. Scollon, Ed Diener

Research Collection School of Social Sciences

When individuals choose future activities on the basis of their past experiences, what guides those choices? The present study compared students' predicted, on-line, and remembered spring-break experiences, as well as the influence of these factors on students' desire to take a similar vacation in the future. Predicted and remembered experiences were both more positive—and, paradoxically, more negative—than on-line experiences. Of key importance, path analyses revealed that remembered experience, but neither on-line nor anticipated experience, directly predicted the desire to repeat the experience. These results suggest that although on-line measures may be superior to retrospective measures for approximating objective experience, retrospective …

Trading Your Neighbor's Etfs: Competition Or Fragmentation?, Beatrice Boehmer, Ekkehart Boehmer Sep 2003

Trading Your Neighbor's Etfs: Competition Or Fragmentation?, Beatrice Boehmer, Ekkehart Boehmer

Research Collection Lee Kong Chian School Of Business

On July 31, 2001, for the first time in its history, the New York Stock Exchange (NYSE) began trading three unlisted securities. The DIA, SPY, and QQQ are the most actively traded Exchange Traded Funds (ETFs) and are listed on the American Stock Exchange. On April 15, 2002 another 27 ETFs followed. These two events provide a unique experiment for studying the impact of a new entrant on market quality. In contrast to recently revived concerns about the adverse impact of market fragmentation, we document that the NYSE entry leads to a dramatic improvement in liquidity that we attribute to …

Design Of Antiresonant-Reflecting Optical Waveguide-Type Vertical-Coupled Surface-Emitting Lasers Using Transfer Matrix Method, Chyng Wen Tee, C. C. Tan, S. F. Yu Sep 2003

Design Of Antiresonant-Reflecting Optical Waveguide-Type Vertical-Coupled Surface-Emitting Lasers Using Transfer Matrix Method, Chyng Wen Tee, C. C. Tan, S. F. Yu

Research Collection Lee Kong Chian School Of Business

A simple transfer matrix method is proposed to calculate the radiation losses of a cylindrical antiresonant-reflecting optical waveguide (ARROW). It is found that the planar approximation underestimates the radiation losses but overestimates the design tolerance of the ARROW-type vertical-cavity surface-emitting lasers (VCSELs). An iteration technique, which is incorporated with the transfer matrix method, is also developed to design ARROW-type VCSELs for minimum radiation losses in a more effective manner.

For A Few Euros More: Campaign Spending Effects In The Irish Local Elections Of 1999, Kenneth Benoit, Michael Marsh Sep 2003

For A Few Euros More: Campaign Spending Effects In The Irish Local Elections Of 1999, Kenneth Benoit, Michael Marsh

Research Collection School of Social Sciences

Although perceived by candidates and parties as important in affecting political outcomes, the link between spending and success in multi-candidate, multiparty election campaigns remains unproven. Not only are there relatively few studies of campaign spending effects in multi-party systems, there are none examining the effect under the Single Transferable Vote (STV) electoral system. Our study examines spending effects in the Irish local elections of 1999 using STV with district magnitudes between 3 and 7 seats, contested by a median of 10 candidates in each district. Using detailed data on 1,838 candidates from 180 local constituencies and 30 councils, we provide …

On Mining Group Patterns Of Mobile Users, Yida Wang, Ee Peng Lim, San-Yih Hwang Sep 2003

On Mining Group Patterns Of Mobile Users, Yida Wang, Ee Peng Lim, San-Yih Hwang

Research Collection School Of Computing and Information Systems

In this paper, we present a group pattern mining approach to derive the grouping information of mobile device users based on the spatio-temporal distances among them. Group patterns of users are determined by a distance threshold and a minimum duration. To discover group patterns, we propose the AGP and VG-growth algorithms that are derived from the Apriori and FP-growth algorithms respectively. We further evaluate the efficiencies of these two algorithms using synthetically generated user movement data.

Interorganizational Systems And Competitive Advantages – Lessons From History, Keng Siau Sep 2003

Interorganizational Systems And Competitive Advantages – Lessons From History, Keng Siau

Research Collection School Of Computing and Information Systems

Global business constantly faces radical transformations stemming from advances in information technology (IT). The concept of gaining competitive advantages by linking information systems across organizations (e.g., supply chain integration) has taken on an overtone of dogma in many business circles. Such electronic linkages are known as Interorganizational Systems (IOS). Lately, the growing importance and easy accessibility of the Internet have propelled IOS to a new height. Undoubtedly, IOS can have a great impact on organizational performance and industry structure. However, IT such as the Internet is readily available to all companies, and most IOS concepts can be easily replicated. Followers …

The Role Of United Charities In Fundraising: The Case Of Singapore, Vincent Chua, Chung Ming Wong Sep 2003

The Role Of United Charities In Fundraising: The Case Of Singapore, Vincent Chua, Chung Ming Wong

Research Collection School Of Economics

Theory suggests that a united charity helps to economize on fundraising costs by reducing competition for donations among member charities. However, donors often cannot control the allocation of their donations, and charities may dislike the monitoring of their activities. This paper examines these and other issues relating to the Community Chest of Singapore. The results, based on analysis of financial positions and fundraising costs of a large number of charities, suggest that the Community Chest does possess important fundraising advantages. Thus charities in financial difficulties or in need of funds for additional programs tend to seek membership. However, organizations that …

An Empirical Examination Of Ipo Underpricing In The Chinese A-Share Market, Ting Yu, Yiu Kuen Tse Sep 2003

An Empirical Examination Of Ipo Underpricing In The Chinese A-Share Market, Ting Yu, Yiu Kuen Tse

Research Collection School Of Economics

Research in the literature shows that initial public offerings (IPOs) of common stocks are systematically priced at a discount to their subsequent initial trading price. The large underpricing magnitude in the Chinese IPO market has attracted much attention. We consider three hypotheses that may explain the IPO underpricing in China. These are the winner's curse hypothesis, the ex ante uncertainty hypothesis and the signaling hypothesis. Among these hypotheses, the winner's curse hypothesis has not been tested in the Chinese market. Using IPO data for online fixed-price offerings from November 1995 to December 1998, our results show that the winner's curse …

Ssm: Fast Construction Of The Optimized Segment Support Map, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim Sep 2003

Ssm: Fast Construction Of The Optimized Segment Support Map, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Computing the frequency of a pattern is one of the key operations in data mining algorithms. Recently, the Optimized Segment Support Map (OSSM) was introduced as a simple but powerful way of speeding up any form of frequency counting satisfying the monotonicity condition. However, the construction cost to obtain the ideal OSSM is high, and makes it less attractive in practice. In this paper, we propose the FSSM, a novel algorithm that constructs the OSSM quickly using a FP-Tree. Given a user-defined segment size, the FSSM is able to construct the OSSM at a fraction of the time required by …

Re-Engaging Chineseness: Political, Economic And Cultural Imperatives Of Nation-Building In Singapore, Eugene K. B. Tan Sep 2003

Re-Engaging Chineseness: Political, Economic And Cultural Imperatives Of Nation-Building In Singapore, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

This article examines the management of Chinese identity and culture since Singapore attained independence in 1965. Due to the delicate regional environment, ethnic Chinese identity has been closely managed by the ruling elites, which have been dominated by the English-educated Chinese. There is the evolution from a deliberate policy of maintaining a low-key ethnic Chinese profile to the recent effort to re-sinicize--in form--the majority ethnic group. The article examines the policy impulses and implications for such a landmark change in reconceptualizing the Chinese-Singapore identity, which can be attributed to the needs of regime maintenance buttressed by Confucian ethos as well …

Reasoning About Competitive Reactions: Evidence From Executives, David B. Montgomery, Marian Chapman Moore, Joel E. Urbany Sep 2003

Reasoning About Competitive Reactions: Evidence From Executives, David B. Montgomery, Marian Chapman Moore, Joel E. Urbany

Research Collection Lee Kong Chian School Of Business

Much of the empirical research on competitive reactions describes how or why rivals react to a firm’s past actions, but stops short of examining whether managers attempt to predict such reactions, which we call strategic competitive reasoning. In three exploratory studies, we find evidence of managers’ thinking about competitors’ past and future behavior, but little incidence of strategic competitive reasoning. Competitive intelligence experts and other experienced managers assessment of the results suggests the relatively low incidence of strategic competitor reasoning is due to perceptions of low returns from anticipating competitor reactions more than to the high cost of doing so. …

Estimating Credit Risk Premia, Kian Guan Lim Sep 2003

Estimating Credit Risk Premia, Kian Guan Lim

Research Collection Lee Kong Chian School Of Business

This paper investigates the nature of the credit risk premium adjustments in the Jarrow-Lando-Turnbull model of credit risk spreads. The adjustments relate the equivalent martingale measures to the empirical measures of unconditional transition probabilities. We provide a modi ed version of the risk adjustment that allows a linear partition of the credit spread into an unconditional default component, a recovery component, and the risk premium adjustment. The risk adjustments are related to conditional default risk, illiquidity risk, and other factors not related to recovery e ects. The log-transform of these risk adjustments can be speci ed as linear regressions on …

Asymptotic Dynamics And Value-At-Risk Of Large Diversified Portfolios In A Jump-Diffusion Market, Kian Guan Lim, Xiaoqing Liu, Kai Chong Tsui Sep 2003

Asymptotic Dynamics And Value-At-Risk Of Large Diversified Portfolios In A Jump-Diffusion Market, Kian Guan Lim, Xiaoqing Liu, Kai Chong Tsui

Research Collection Lee Kong Chian School Of Business

This paper studies the modelling of large diversi ed portfolios in a nancial market with jump-di usion risks. The portfolios considered include three categories: equal money-weighted portfolios, risk minimizing portfolios, and market indices. Reduced-form dynamics driven jointly by one Brownian Motion and one Poisson process are derived for the asymptotics of such portfolios. We prove that derivatives written on a portfolio can be priced by treating the asymptotic dynamics as the underlying process if the number of assets in the portfolio is su ciently large. Analytical and Monte Carlo Value-at-Risk (VaR) can be computed for the portfolios based on their …

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu Sep 2003

Stock Exchange Governance And Market Quality, Chandrasekhar Krishnamurti, John M. Sequeira, Fangjian Fu

Research Collection Lee Kong Chian School Of Business

We show that organization structure of a stock exchange matters by utilizing the unique setting prevailing in India. India has two major stock markets, the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). These two exchanges adopt similar trading systems, trade essentially identical stocks, and follow the same trading hours. However, these exchanges have different organizational structures: BSE is mutualized whereas NSE is demutualized. Using the Hasbrouck [Review of Financial Studies 6 (1993) 191] measure of market quality we show that NSE provides a better quality market than BSE. This result is consistent with the work of Domowitz …

Does Underwriter Reputation Affect The Performance Of Ipo Stocks?, Chunchi Wu, Sheen Liu, Junbo Wang Sep 2003

Does Underwriter Reputation Affect The Performance Of Ipo Stocks?, Chunchi Wu, Sheen Liu, Junbo Wang

Research Collection Lee Kong Chian School Of Business

In this paper we examine the relationship between performance of the Chinese IPO firms and the reputation of investment bankers underwriting their stocks. Similar to previous studies on well-developed stock markets, we find that the initial return on the first day of trading is strongly positive for Chinese IPO stocks due to underpricing. This initial return is negatively related to the underwriter's reputation, suggesting that the better the reputation of the underwriter, the less underpricing and hence, the lower the initial return of the IPO stock. Extending the analysis to a ten-day window after the first trading day, we find …
