The Importance Of Traits And Abilities In Supervisors' Hirability Decisions As A Function Of Method Of Assessment, Filip Lievens, Scott Highhouse, Wilfried De Corte Sep 2005

The Importance Of Traits And Abilities In Supervisors' Hirability Decisions As A Function Of Method Of Assessment, Filip Lievens, Scott Highhouse, Wilfried De Corte

Research Collection Lee Kong Chian School Of Business

Past research on the importance of traits and abilities in supervisors' hirability decisions has ignored the influence of the selection method used to derive information about these traits and abilities. In this study, experienced retail store supervisors (N = 163) rated job applicant profiles that were described on the Big Five and General Mental Ability (GMA) personality dimensions. Contrary to past studies, the supervisors were also informed about the method of assessment used (paper-and-pencil test vs. unstructured interview). Hierarchical linear modelling analyses showed that the importance attached to extraversion and GMA was significantly moderated by the selection method, with extraversion …

Recruitment-Related Information Sources And Organizational Attractiveness: Can Something Be Done About Negative Publicity?, Greet Van Hoye, Filip Lievens Sep 2005

Recruitment-Related Information Sources And Organizational Attractiveness: Can Something Be Done About Negative Publicity?, Greet Van Hoye, Filip Lievens

Research Collection Lee Kong Chian School Of Business

The present study begins to fill a gap in the recruitment literature by investigating whether the effects of negative publicity on organizational attractiveness can be mitigated by recruitment advertising and positive word-of-mouth. The accessibility-diagnosticity model was used as a theoretical framework to formulate predictions about the effects of these recruitment-related information sources. A mixed 2 x 2 experimental design was applied to examine whether initial assessments of organizational attractiveness based on negative publicity would improve at a second evaluation after exposure to a second, more positive information source. We found that both recruitment advertising and word-of-mouth improved organizational attractiveness, but …

Defining The 'Social' In 'Social Entrepreneurship': Altruism And Entrepreneurship, Wee Liang Tan, John N. Williams, Teck Meng Tan Sep 2005

Defining The 'Social' In 'Social Entrepreneurship': Altruism And Entrepreneurship, Wee Liang Tan, John N. Williams, Teck Meng Tan

Research Collection Lee Kong Chian School Of Business

What is social entrepreneurship? In, particular, what’s so social about it? Understanding what social entrepreneurship is enables researchers to study the phenomenon and policy-makers to design measures to encourage it. However, such an understanding is lacking partly because there is no universally accepted definition of entrepreneurship as yet. In this paper, we suggest a definition of social entrepreneurship that intuitively accords with what is generally accepted as entrepreneurship and that captures the way in which entrepreneurship may be altruistic. Based on this we provide a taxonomy of social entrepreneurship and identify a number of real cases from Asia illustrating the …

Antecedents, Consequences, And The Mediating Role Of Organizational Innovation: Empirical Generalizations, Leslie H. Vincent, Sundar G. Bharadwaj, Goutam N. Challagalla Sep 2005

Antecedents, Consequences, And The Mediating Role Of Organizational Innovation: Empirical Generalizations, Leslie H. Vincent, Sundar G. Bharadwaj, Goutam N. Challagalla

Research Collection Lee Kong Chian School Of Business

This study uses emerging meta-analytic methods, in combination with structural equations methodology, to synthesize empirical studies and extend the understanding of relationships amongthe correlates (antecedents and/or outcomes) of innovation in organizations. this study draws upon a meta-analytic database of 155 independent samples from 108 studies from the period of 1970 through 2004. Specifically, the study examines the impact of 26 determinants and 3 performance outcomes of innovation with an overall sample size of 229,395. Organizational resources account for the majority of unique variance explained in predicting innovation generation. Overall findings indicate that innovation is significantly and positively related to superior …

Understanding Interpersonal Trust In A Confucian-Influenced Society: An Exploratory Study, Hwee Hoon Tan, Dave Chee Aug 2005

Understanding Interpersonal Trust In A Confucian-Influenced Society: An Exploratory Study, Hwee Hoon Tan, Dave Chee

Research Collection Lee Kong Chian School Of Business

Adopting a qualitative methodology, this exploratory study examined the construct of trust and its factors of trustworthiness as perceived in a Confucian-influenced society. The findings of our study indicated that there are emic differences in the meaning of trust as perceived in a Confucian-influenced setting. Specifically, we found a heavy reliance on affective factors of trustworthiness in the decision to trust. In addition, we found a number of factors unique to the context that facilitates the development of trust: diligence, perseverance, filial piety, thriftiness, respect for authority, a shared value of collective effort, harmonious relationship in the office, humbleness and …

Slack Resources And The Performance Of Privately Held Firms, Gerard George Aug 2005

Slack Resources And The Performance Of Privately Held Firms, Gerard George

Research Collection Lee Kong Chian School Of Business

Empirical findings from publicly traded firms and behavioral arguments suggest a positive influence of resource slack on financial performance. While this area has remained unexplored in privately held firms, conceptual arguments indicate that resource constraints may enhance performance. Longitudinal data on 900 privately held firms confirm the differing influences of forms of slack on performance. Results indicate that a combination of behavioral and resource constraints arguments are necessary to explain the slack-performance relationship in privately held firms. The implications of these findings for theories of resources and entrepreneurship are discussed.

Implied Measures Of Relative Fund Performance, Steve Hogan, Mitchell Craig Warachka Aug 2005

Implied Measures Of Relative Fund Performance, Steve Hogan, Mitchell Craig Warachka

Research Collection Lee Kong Chian School Of Business

We evaluate the relative performance of funds by conditioning their returns on the cross-section of portfolio characteristics across fund managers. Our implied procedure circumvents the need to specify benchmark returns or peer funds. Instead, fund-specific benchmarks for measuring selection and market timing ability are constructed. This technique is robust to herding as well as window dressing and mitigates survivorship bias. Empirically, the conditional information contained in portfolio weights defined by industry sectors, assets and geographical regions is critically important to the assessment of fund management. For each set of portfolio characteristics, we identify funds with success at either selecting securities …

A Dynamic Model For The Forward Curve, Choong Tze Chua, Foster Dean, Krishna Ramaswamy, Robert Stine Aug 2005

A Dynamic Model For The Forward Curve, Choong Tze Chua, Foster Dean, Krishna Ramaswamy, Robert Stine

Research Collection Lee Kong Chian School Of Business

This paper develops and estimates a dynamic arbitrage-free model for the current forward curve as the sum of (i) an unconditional component, (ii) a maturity-specific component and (iii) a date-specific component. The model combines features of the Preferred Habitat model,the Expectation Hypothesis and affine yield curve models. We show how to construct alternative parametric examples of the three components from a sum of exponential functions, verify that the resulting forward curves satisfy the Heath-Jarrow-Morton conditions, and derive the risk-neutral dynamics for the purpose of pricing interest rate derivatives. We select a model from alternative affine examples that are fitted to …

Too Little Or Too Much? Reexamining The Relationship Between Corporate Charitable Giving And Corporate Financial Performance, Heli Wang, Jaepil Choi, Jiatao Li Aug 2005

Too Little Or Too Much? Reexamining The Relationship Between Corporate Charitable Giving And Corporate Financial Performance, Heli Wang, Jaepil Choi, Jiatao Li

Research Collection Lee Kong Chian School Of Business

How do corporate charitable contributions affect corporate financial performance? Instrumental stakeholder theory posits that corporate giving can lead to high levels of corporate financial performance through improved stakeholder relations. In contrast, agency theory suggests that corporate giving diverts valuable corporate resources and inhibits corporate financial performance. Extant empirical studies that have examined the relationship found inconclusive results. We depart from and extend the existing literature in two main aspects. First, building upon the instrumental stakeholder argument and agency perspective, we develop the argument that there is an inverse U-shaped relationship between corporate charitable giving and corporate financial performance. Second, we …

Evaluation Of Time-Varying Availability In Multi-Echelon Inventory System With Combat Damage, Hoong Chuin Lau, Huawei Song Aug 2005

Evaluation Of Time-Varying Availability In Multi-Echelon Inventory System With Combat Damage, Hoong Chuin Lau, Huawei Song

Research Collection School Of Computing and Information Systems

The models for multi-echelon inventory systems in existing literatures predominantly address failures due to reliability in peacetime. In wartime or even peacetime operational scenarios, unexpected combat damage can cause a large number of systems to be heavily damaged, to the extent that they become irreparable. In this paper, we study a multi-echelon spare parts support system under combat damage, discuss the replenishment policy and propose an approximate method to evaluate the time-varying system performance operational availability considering the effect of passivation. Experiments show our model works well and efficiently against simulation.

Profiting From Mean-Reverting Yield Curve Trading Strategies, Choong Tze Chua, Winston T. H. Koh, Krishna Ramaswamy Aug 2005

Profiting From Mean-Reverting Yield Curve Trading Strategies, Choong Tze Chua, Winston T. H. Koh, Krishna Ramaswamy

Research Collection Lee Kong Chian School Of Business

A large class of fixed income trading strategies focuses on opportunities offered by the interest rate term structure. This paper studies a set of yield curve trading strategies that are based on the view that the yield curve mean-reverts to an unconditional curve. These mean-reverting trading strategies exploit deviations in the level, slope and curvature of the yield curve from historical norms. We consider cash-neutral trades with one-month holding periods. Some mean-reverting strategies were found to be highly profitable, and outperform, on a risk-adjusted basis before transaction costs, alternative strategies of an investment in the Lehman Brothers Bond index (by …

Word-Of Mouth Transmission In Settings With Multiple Opinions: The Impact Of Other Opinions On Wom Intention And Strength, Gangseog Ryu, Lawrence Feick, Jin K. Han Aug 2005

Word-Of Mouth Transmission In Settings With Multiple Opinions: The Impact Of Other Opinions On Wom Intention And Strength, Gangseog Ryu, Lawrence Feick, Jin K. Han

Research Collection Lee Kong Chian School Of Business

In two experiments we examine word-of-mouth (WOM) in multiple opinion settings. In Study 1, we find that (generally) the presence of congruent other opinions tended to increase the likelihood and strength of WOM compared to a situation when there was no other opinion. In addition, incongruent other opinions also have a tendency to increase WOM likelihood, but reduced strength compared to when no other opinions were present. Further, we find that consumerÆs level of satisfaction and strength of social tie to the recipient moderated the effect of opinion congruence. In Study 2, we generally replicate the results in Study 1 …

Exploiting Belief Bounds: Practical Pomdps For Personal Assistant Agents, Pradeep Varakantham, Rajiv Maheswaran, Milind Tambe Jul 2005

Exploiting Belief Bounds: Practical Pomdps For Personal Assistant Agents, Pradeep Varakantham, Rajiv Maheswaran, Milind Tambe

Research Collection School Of Computing and Information Systems

Agents or agent teams deployed to assist humans often face the challenges of monitoring the state of key processes in their environment (including the state of their human users themselves) and making periodic decisions based on such monitoring. POMDPs appear well suited to enable agents to address these challenges, given the uncertain environment and cost of actions, but optimal policy generation for POMDPs is computationally expensive. This paper introduces three key techniques to speedup POMDP policy generation that exploit the notion of progress or dynamics in personal assistant domains. Policy computation is restricted to the belief space polytope that remains …

The Korean Language And The Effects Of Its Honorifics System In Advertising: Deferential Vs. Informal Speech As Regulatory Prime On Persuasive Impact, Jin K. Han, Yong Seok Sohn, Kun Woo Yoo Jul 2005

The Korean Language And The Effects Of Its Honorifics System In Advertising: Deferential Vs. Informal Speech As Regulatory Prime On Persuasive Impact, Jin K. Han, Yong Seok Sohn, Kun Woo Yoo

Research Collection Lee Kong Chian School Of Business

A very prominent feature of the Korean language is its extensive honorifics system, where the speaker is obliged to adopt a level of speech (deferential vs. informal) befitting the status of the target audience. As the context for using deferential (informal) speech parallels the setting for prevention (promotion) focus, we set out to examine whether the Korean honorifics system itself functions as a natural prime for regulatory orientation. In Study 1, we find that deferential (informal) speech style activates prevention (promotion) focus in the addressee. Accordingly, we show that ad copies in deferential (informal) speech style resulted in regulatory fit …

On The Intertemporal Risk-Return Relation: A Bayesian Model Comparison Perspective, Leping Wang Jul 2005

On The Intertemporal Risk-Return Relation: A Bayesian Model Comparison Perspective, Leping Wang

Research Collection Lee Kong Chian School Of Business

The existing empirical studies indicate that inferences on the intertemporal relation between expected return and volatility are highly sensitive to empirical specifications of return dynamics. Glosten, Jagannathan, and Runkle (1993) attempt to resolve this confusing situation by examining several generalizations of the standard GARCH-M model. They conclude a negative risk-return relation solely based on the models that are identified in the first step through a variety of diagnostic tests as relatively “better” models. However, it has not been shown in their study whether the evidence supporting their first-step model selection decision is significant or not. To the extent the strength …

Regret In Cancer-Related Decisions, Terry Connolly, Jochen Reb Jul 2005

Regret In Cancer-Related Decisions, Terry Connolly, Jochen Reb

Research Collection Lee Kong Chian School Of Business

Decision-related regret is a negative emotion associated with thinking about a past or future choice. The thinking component generally takes the form of a wish that things were otherwise and involves a comparison of what actually did or will take place with some better alternative--a counterfactual thought. For predecisional (anticipated) regret, the thinking involves a mental simulation of the outcomes that might result from different choice options. Prior research has focused on regret associated with decision outcomes, addressing especially (a) the comparison outcome selected and (b) whether the outcome resulted from action or inaction. More recent research examines regret associated …

Staying Ahead Of The Competition: Insights From Singapore's Manufacturing Enclave In Vietnam, Caroline Yeoh, Di Kun Goh, Wilfred Pow Ngee How Jul 2005

Staying Ahead Of The Competition: Insights From Singapore's Manufacturing Enclave In Vietnam, Caroline Yeoh, Di Kun Goh, Wilfred Pow Ngee How

Research Collection Lee Kong Chian School Of Business

The apparent success of Singapore-styled industrial parks in attracting foreign investments into the emerging Asian economies to capitalize on cheap and abundant resources has led, pari passu, to a mushrooming of similarly-patterned competitor parks in close proximity to the flagship projects. Many of the competitor parks offer either similar or comparable facilities, lower rates, or, in some cases, both. The ensuing dynamic competitive interactions between the competitor parks and the Singapore-styled parks have forced a re-examination of the viability of the Singapore advantage in navigating the economics of competition, and in sustaining competitive advantage. The Vietnam-Singapore Industrial Park (VSIP), unsurprisingly, …

How Much You Watch, How Much You Pay, Yongdong Wu, Hwee Hwa Pang, Robert H. Deng Jul 2005

How Much You Watch, How Much You Pay, Yongdong Wu, Hwee Hwa Pang, Robert H. Deng

Research Collection School Of Computing and Information Systems

This paper presents a pay-video scheme that manages video stream, key stream and payment stream efficiently. In our scheme, the owner segments a video into fragments and encrypts them with independent keys. The keys are generated with a novel concept called as hash interval, where each hash interval discloses a range of numbers without disclosing any information on numbers outside of the range. The video fragments are then broadcast on one or more channels. A buyer can purchase the keys to decrypt any fragments and, within each fragment, any desired quality level. The accompanying payment protocol is integrated with the …

Why Is Management A Cliché?, Stefano Harney Jul 2005

Why Is Management A Cliché?, Stefano Harney

Research Collection Lee Kong Chian School Of Business

This article introduces the term demotics of management by asking why so much management literature reads like a cliché. Typically this question has been approached by seeing the cliché as strategic. This article instead views the cliché as symptomatic. It marks a growing problem—how can management track labor out of the workplace and into the realm of social reproduction, a realm that is increasingly, with the tendency of immaterial labor, directly productive. This problem has produced not only the explosion of popular management literature, particularly in the United States, in the last 20 years, but also what might be called …

Enclaves For Enterprise: An Empirical Study Of Singapore's Industrial Parks In Indonesia, Vietnam And China, Caroline Yeoh, Wilfred Pow Ngee How, Ai Lin Leong

Research Collection Lee Kong Chian School Of Business

The dynamics of globalization have prompted governments to re-examine accustomed policies, and search for alternative strategies, in order to re-position their economies for the future. This paper explores the spatial context of state involvement in the new economics of competition, with the focus on Singapore’s much publicized, and controversial, orchestration of its state enterprise network to encapsulate economic space for Singapore-based firms to expand into the Asian region. This strategic initiative is promulgated on the exportability of Singapore’s ‘state credibility’, systemic and operational efficiencies, and technological competencies, to locations where these attributes are less certain. A logit model is applied …

Do Suppliers Benefit From Collaborative Relationships With Large Retailers? An Empirical Investigation Of Efficient Consumer Response Adoption, Daniel Corsten, Nirmalya Kumar Jul 2005

Do Suppliers Benefit From Collaborative Relationships With Large Retailers? An Empirical Investigation Of Efficient Consumer Response Adoption, Daniel Corsten, Nirmalya Kumar

Research Collection Lee Kong Chian School Of Business

Collaborative manufacturer-retailer relationships based on efficient consumer response (ECR) have become ubiquitous over the past decade. Yet academic studies of ECR adoption and its impact on marketing relationships are relatively scarce. Inspired by the relational view of competitive advantage, the authors empirically investigate whether the extent to which suppliers of a major retailer adopt ECR has a beneficial impact on their outcomes. The results demonstrate that whereas ECR adoption has a positive impact on supplier economic performance and capability development, it also generates greater perceptions of negative inequity on the part of the supplier. However, retailer capabilities and supplier trust …

Jackknifing Bond Option Prices, Peter C. B. Phillips, Jun Yu Jun 2005

Jackknifing Bond Option Prices, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

Prices of interest rate derivative securities depend crucially on the mean reversion parameters of the underlying diffusions. These parameters are subject to estimation bias when standard methods are used. The estimation bias can be substantial even in very large samples and much more serious than the discretization bias, and it translates into a bias in pricing bond options and other derivative securities that is important in practical work. This article proposes a very general and computationally inexpensive method of bias reduction that is based on Quenouille's (1956; Biometrika, 43, 353-360) jackknife. We show how the method can be applied directly …

A Two-Stage Realized Volatility Approach To The Estimation For Diffusion Processes From Discrete Observations, Peter C. B. Phillips, Jun Yu Jun 2005

A Two-Stage Realized Volatility Approach To The Estimation For Diffusion Processes From Discrete Observations, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper motivates and introduces a two-stage method for estimating diffusion processes based on discretely sampled observations. In the first stage we make use of the feasible central limit theory for realized volatility, as recently developed in Barndorff-Nielsen and Shephard (2002), to provide a regression model for estimating the parameters in the diffusion function. In the second stage the in-fill likelihood function is derived by means of the Girsanov theorem and then used to estimate the parameters in the drift function. Consistency and asymptotic distribution theory for these estimates are established in various contexts. The finite sample performance of the …

The Effect Of Remanufacturing On Procurement Decisions For Resellers In Secondary Markets, Andreas Robotis, Shantanu Bhattacharya, Luk N. Van Wassenhove Jun 2005

The Effect Of Remanufacturing On Procurement Decisions For Resellers In Secondary Markets, Andreas Robotis, Shantanu Bhattacharya, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

The role of remanufacturing as a competitive tool for firms has been reflected in a number of studies to show that remanufacturing can reduce the unit cost of production by reusing components. However, the fact that remanufacturing can be used as a strategic tool for serving secondary markets as well has not been acknowledged in the literature. In this paper, we study the use of remanufacturing as a tool to serve secondary markets. Specifically, we model the case of a reseller who procures used products based on an older generation of technology from an advanced market and then uses one …

Interaction Of Technology Choice And Financial Risk Management Under Costly External Financing, Onur Boyabatli, L. Beril Toktay Jun 2005

Interaction Of Technology Choice And Financial Risk Management Under Costly External Financing, Onur Boyabatli, L. Beril Toktay

Research Collection Lee Kong Chian School Of Business

This paper analyzes the integrated operational and financial risk management portfolio of a firm that determines whether to use flexible or dedicated technology and whether to undertake financial risk management or not. The risk management value of flexible technology is due to its risk pooling benefit under demand uncertainty. The financial risk management motivation comes from the existence of deadweight costs of external financing due to capital market imperfections. Financial risk management has a fixed cost, while technology investment incurs both fixed and variable costs. The firm's limited budget, which depends partly on a tradable asset, can be increased by …
