The Image Of Psychology Programs: The Value Of The Instrumental-Symbolic Framework, Greet Van Hoye, Filip Lievens, Britt De Soete, Nele Libbrecht, Eveline Schollaert, Dimphna Baligant Jul 2014

The Image Of Psychology Programs: The Value Of The Instrumental-Symbolic Framework, Greet Van Hoye, Filip Lievens, Britt De Soete, Nele Libbrecht, Eveline Schollaert, Dimphna Baligant

Research Collection Lee Kong Chian School Of Business

As competition for funding and students intensifies, it becomes increasingly important for psychology programs to have an image that is attractive and makes them stand out from other programs. The current study uses the instrumental-symbolic framework from the marketing domain to determine the image of different master's programs in psychology and examines how these image dimensions relate to student attraction and competitor differentiation. The samples consist of both potential students (N = 114) and current students (N = 68) of three psychology programs at a Belgian university: industrial and organizational psychology, clinical psychology, and experimental psychology. The results demonstrate that …

Cellular Bucket Brigades On U-Lines With Discrete Work Stations, Yun Fong Lim, Yue Wu Jul 2014

Cellular Bucket Brigades On U-Lines With Discrete Work Stations, Yun Fong Lim, Yue Wu

Research Collection Lee Kong Chian School Of Business

It is challenging to maximize and maintain productivity of a U-line with discrete stations under the impact of variability. This is because maximizing productivity requires assigning workers to suitable tasks and maintaining productivity requires sufficient flexibility in task assignment to absorb the impact of variability. To achieve this goal, we propose an operating protocol to coordinate workers on the U-line. Under the protocol the system can be configured such that its productivity is maximized. Workers are allowed to dynamically share work so that the system can effectively absorb the impact of variability. Analysis based on a deterministic model shows that …

Within-Person Variability In Job Performance: An Integrative Review And Research Agenda, Reeshad S. Dalal, Devasheesh P. Bhave, John Fiset Jul 2014

Within-Person Variability In Job Performance: An Integrative Review And Research Agenda, Reeshad S. Dalal, Devasheesh P. Bhave, John Fiset

Research Collection Lee Kong Chian School Of Business

Although both researchers and practitioners know that an employee’s performance varies over time within a job, this within-person performance variability is not well understood and in fact is often treated as error. In the current paper, we first identify the importance of a within-person approach to job performance and then review several extant theories of within-person performance variability that, despite vastly different foci, converge on the contention that job performance is dynamic rather than static. We compare and contrast the theories along several common metrics and thereby facilitate a discussion of commonalities, differences, and theory elaboration. In so doing, we …

Dynamic Pricing In The Singapore Condominium Market, Eric Fesselmeyer, Haoming Liu Jul 2014

Dynamic Pricing In The Singapore Condominium Market, Eric Fesselmeyer, Haoming Liu

Research Collection College of Integrative Studies

Dynamic pricing strategies are likely an important consideration of Singapore condominium developers because of the durability of condominiums, price transparency, and the long sales period. While we do not observe any systematic relationship between the new sale prices and time of purchase, we do find that quality-adjusted price increases and the quality of units purchased decreases over the new sale period. These results suggest that condominium developers allow early buyers to purchase high quality units at discounted prices but do not extend the price discount to later buyers of low quality units.

Board Interlock Networks And The Use Of Relative Performance Evaluation, Qian Hao, Nan Hu, Ling Liu, Lee J. Yao Jul 2014

Board Interlock Networks And The Use Of Relative Performance Evaluation, Qian Hao, Nan Hu, Ling Liu, Lee J. Yao

Research Collection School Of Computing and Information Systems

Purpose - The purpose of this paper is to explore how networks of boards of directors affect relative performance evaluation (RPE) in chief executive officer (CEO) compensation. Design/methodology/approach - In this study, the authors propose that an interlocking network is an important inter-corporate setting, which has a bearing on whether boards decide to use RPE in CEO compensation. They adopt four typical graph measures to depict the centrality/position of each board in the interlock network: degree, betweenness, eigenvector and closeness, and study their impacts on RPE use. Findings - The authors find that firms that have more connected board members …

Near-Optimal Nonmyopic Contact Center Planning Using Dual Decomposition, Akshat Kumar, Sudhanshu Singh, Pranav Gupta, Gyana Parija Jul 2014

Near-Optimal Nonmyopic Contact Center Planning Using Dual Decomposition, Akshat Kumar, Sudhanshu Singh, Pranav Gupta, Gyana Parija

Research Collection School Of Computing and Information Systems

We address the problem of minimizing staffing cost in a contact center subject to service level requirements over multiple weeks. We handle both the capacity planning and agent schedule generation aspect of this problem. Our work incorporates two unique business requirements. First, we develop techniques that can provide near-optimal staffing for 247 contact centers over long term, upto eight weeks, rather than planning myopically on a week-on-week basis. Second, our approach is usable in an online interactive setting in which staffing managers using our system expect high quality plans within a short time period. Results on large real world and …

Societal Trust And Corporate Tax Avoidance, Kiridaran Kanagaretnam, Jimmy Lee, Chee Yeow Lim, Gerald J. Lobo Jun 2014

Societal Trust And Corporate Tax Avoidance, Kiridaran Kanagaretnam, Jimmy Lee, Chee Yeow Lim, Gerald J. Lobo

Research Collection School Of Accountancy

Using an international sample of firms and a country-level index for societal trust, we study how differences in trust across countries relate to corporate tax avoidance. Consistent with our prediction, we find strong evidence that societal trust is negatively associated with corporate tax avoidance by firms, even after controlling for other determinants such as home country tax system characteristics. We also explore the effects of three country-level institutional characteristics – level of investor protection, disclosure requirement, and tax enforcement – on the relation between societal trust and tax avoidance. We predict and find that the effects of trust on tax …

The Risk-Relevance Of Securitizations During The Recent Financial Crisis, Yiwei Dou, Yanju Liu, Gordon Richardson, Dushyantkumar Vyas Jun 2014

The Risk-Relevance Of Securitizations During The Recent Financial Crisis, Yiwei Dou, Yanju Liu, Gordon Richardson, Dushyantkumar Vyas

Research Collection School Of Accountancy

We investigate changes in the risk-relevance of securitized subprime, other nonconforming, and commercial mortgages for sponsor-originators during the recent financial crisis. Using the volatility of realized stock returns, option-implied volatility, and credit spreads, we observe a pronounced increase in the risk-relevance of subprime securitizations as early as 2006. Furthermore, reflecting the evolution of the financial crisis in waves, we find that investors recognized the increased credit risk of other nonconforming and commercial mortgage securitizations as the financial crisis progressed. Additional analyses show that risk-relevance varies cross-sectionally with structural characteristics such as monoline credit-enhancement and the presence of special servicers for …

Industry-Based Style Investing, Russell Jame, Qing Tong Jun 2014

Industry-Based Style Investing, Russell Jame, Qing Tong

Research Collection Lee Kong Chian School Of Business

Motivated by the style investing model of Barberis and Shleifer (2003), we examine the industry-wide investment decisions of retail investors. We find that retail investor industry demand is highly correlated and strongly related to past industry returns. Moreover, industries heavily bought by retail investors over the past year significantly underperform industries heavily sold over the subsequent year. Similarly, stocks in industries heavily bought by retail investors underperform stocks in industries heavily sold, even after controlling for firm-level demand. Our results suggest that industry-wide categorization influences the investment decisions of retail investors and has a significant impact on asset prices.

Activist Directors: Determinants And Consequences, Ian D Gow, Sa-Pyung Sean Shin, Suraj Srinivasan Jun 2014

Activist Directors: Determinants And Consequences, Ian D Gow, Sa-Pyung Sean Shin, Suraj Srinivasan

Research Collection School Of Accountancy

This paper examines the determinants and consequences of hedge fund activism with a focuson activist directors, i.e., those directors appointed in response to demands by activists.Using a sample of 1,969 activism events over the period 2004–2012, we identify 824 activistdirectors. We find that activists are more likely to gain board seats at smaller firms and thosewith weaker stock price performance. Activists remain as shareholders longer when they haveboard seats, with holding periods consistent with conventional notions of “long-term” institutionalinvestors. As in prior research, we find positive announcement-period returns of around4–5% when a firm is targeted by activists, and a 2% …

Managers' Pay Duration And Voluntary Disclosures, Qiang Cheng, Young Jun Cho, Jae Bum Kim Jun 2014

Managers' Pay Duration And Voluntary Disclosures, Qiang Cheng, Young Jun Cho, Jae Bum Kim

Research Collection School Of Accountancy

In this paper, we examine the effect of managers’ pay duration on firms’ voluntary disclosures. Pay duration refers to the average period that it takes for managers’ annual compensation to vest. We hypothesize and find that pay duration can incentivize managers to provide more bad news earnings forecasts. This result holds after controlling for the level of stock-based compensation and the endogeneity of pay duration. In addition, we find that the effect of pay duration is more pronounced for firms with weaker governance and for firms with a more opaque information environment, where the marginal benefits of additional disclosures are …

The Triangular Relationship Between Audit Committee Characteristics, Audit Inputs, And Financial Reporting Quality, Jae Bum Kim, Benjamin Segal, Dan Segal, Yoonseok Zang Jun 2014

The Triangular Relationship Between Audit Committee Characteristics, Audit Inputs, And Financial Reporting Quality, Jae Bum Kim, Benjamin Segal, Dan Segal, Yoonseok Zang

Research Collection School Of Accountancy

Using the exogenous reforms to audit committees mandated by the Sarbanes-Oxley Act of 2002 and a difference-in-difference approach, we examine the impact of changes in audit committee attributes (financial expertise, size, and independence) on firms’ audit inputs and financial reporting quality. Firms directly affected by the reforms experienced a larger improvement in audit inputs (measured by audit fees and the appointment of an industry specialist auditor) and a larger increase in financial reporting quality (measured by restatements of financial reports) relative to firms that were already compliant. Importantly, we find that the decline in restatements is not related to the …

Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh Jun 2014

Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh

Research Collection Lee Kong Chian School Of Business


Research shows that exposure to heat-related cues (e.g., warm temperatures, “fry” and “boil”) influences the belief that global warming exists and poses a serious threat to humans. Drawing on social-cognitive principles of concept accessibility and applicability, we hypothesized that these effects may depend on how the issue is framed, given that heat-related concepts are more compatible with “global warming” than “climate change.” Exploring this possibility, we asked campus passersby about their belief in global warming or climate change shortly after a real-life unseasonably cold weather event (i.e., snowfall during Spring; Study 1). A controlled Web experiment …

Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho Jun 2014

Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho

Research Collection Lee Kong Chian School Of Business

The purpose of this study was to explore the ways in which audiences build parasocial relationships with media characters via reality TV and social media, and its implications for celebrity endorsement and purchase intentions. Using an online survey, this study collected 401 responses from the Korean Wave fans in Singapore. The results showed that reality TV viewing and SNS use to interact with media characters were positively associated with parasocial relationships between media characters and viewers. Parasocial relationships, in turn, were positively associated with the viewers’ perception of endorser and brand credibility, and purchase intention of the brand endorsed by …

Climate Change And Management: From The Editors, Jennifer Howard-Grenville, Simon J. Buckle, Brian J. Hoskins, Gerard George

Research Collection Lee Kong Chian School Of Business

Climate change is one of the greatest challenges we confront in the 21st century. On current trends, by the end of the century, the warming effect of our greenhouse gas emissions will have taken us far away from pre-industrial climatic conditions. In fact, our climate will be as different from pre-industrial conditions as it was when the Earth emerged from the last ice age some 20,000 years ago. In other words, just over 200 years of human and industrial activity will have wrought fundamental change to our climate system. The rise of organizations and industrialized production has set us on …

Modeling Queues With Simulation Versus M/M/C Models, Kum Khiong Yang, Joyce M. W. Low, Cayirli Tugba Jun 2014

Modeling Queues With Simulation Versus M/M/C Models, Kum Khiong Yang, Joyce M. W. Low, Cayirli Tugba

Research Collection Lee Kong Chian School Of Business

This paper examines the performance of single-queue service systems using a combination of computer simulation and M/M/C queuing models. Our results show that the accuracy of M/M/C models is significantly affected by the assumptions supporting the models. Managers should therefore exercise caution in using the M/M/C models for designing queuing systems when the models’ assumptions are violated. Our results show that cost-centric and servicecentric firms should manage their queues differently. While cost-centric firms should target higher arrival load, single service session, and front-loaded arrival pattern for higher efficiency, service-centric firms should strive for lower arrival load, multiple short sessions and …

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu Jun 2014

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu

Research Collection School Of Economics

The paper proposes a self-exciting asset pricing model that takes into account cojumps between prices and volatility and self-exciting jump clustering. We employ a dence of self-exciting jump clustering since the 1987 market crash, and its importance Bayesian learning approach to implement real time sequential analysis. We find evidence of self-exciting jump clustering since the 1987 market crash, and its importance becomes more obvious at the onset of the 2008 global financial crisis. It is found that learning affects the tail behaviors of the return distributions and has important implications for risk management, volatility forecasting and option pricing.

Robust Two-Stage Stochastic Linear Programs With Moment Constraints, Sarah Yini Gao, Lingchen Kong, Jie Sun Jun 2014

Robust Two-Stage Stochastic Linear Programs With Moment Constraints, Sarah Yini Gao, Lingchen Kong, Jie Sun

Research Collection Lee Kong Chian School Of Business

We consider the two-stage stochastic linear programming model, in which the recourse function is a worst case expected value over a set of probabilistic distributions. These distributions share the same first- and second-order moments. By using duality of semi-infinite programming and assuming knowledge on extreme points of the dual polyhedron of the constraints, we show that a deterministic equivalence of the two-stage problem is a second-order cone optimization problem. Numerical examples are presented to show non-conservativeness and computational advantage of this approach.

Service Systems With Finite And Heterogeneous Customer Arrivals, Rowan Wang, Oualid Jouini, Saif Benjaafar Jun 2014

Service Systems With Finite And Heterogeneous Customer Arrivals, Rowan Wang, Oualid Jouini, Saif Benjaafar

Research Collection Lee Kong Chian School Of Business

We consider service systems with a finite number of customer arrivals, where customer interarrival times and service times are both stochastic and heterogeneous. Applications of such systems are numerous and include systems where arrivals are driven by events or service completions in serial processes as well as systems where servers are subject to learning or fatigue. Using an embedded Markov chain approach, we characterize the waiting time distribution for each customer, from which we obtain various performance measures of interest, including the expected waiting time of a specific customer, the expected waiting time of an arbitrary customer, and the expected …

Credit Watch Placement And Security Price Behavior Around Bond Rating Revisions, Chiraphol N. Chiyachantana, Eakapat Manitkajornkit, Nareerat Taechapiroontong Jun 2014

Credit Watch Placement And Security Price Behavior Around Bond Rating Revisions, Chiraphol N. Chiyachantana, Eakapat Manitkajornkit, Nareerat Taechapiroontong

Research Collection Lee Kong Chian School Of Business

This study examines the informational role of credit watch placement in the overall bond rating process from 1992 to 2006. The paper uses standard event study to examine the market reaction of the whole process of credit rating change which includes credit watch placement, transitional period, and actual rating change. The authors find that the act of a company’s bond being put on both positive and negative credit watch placements are associated with significant abnormal returns in the company’s stock while negative credit watch placement helps reduce the negative market reaction on the actual rating downgrade. The paper shows that …

Cost Growth And Stock Returns, Dashan Huang, Fuwei Jiang, Jun Tu, Guofu Zhou Jun 2014

Cost Growth And Stock Returns, Dashan Huang, Fuwei Jiang, Jun Tu, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

In this paper, we examine the valuation implications of cost behavior, and find that firms with high growth rate in operating costs generate substantially lower future stock returns than those with low cost growth. A spread portfolio of long stocks with low cost growth and short stocks with high cost growth earns an average abnormal return of 12% per year. This strategy is robust over time, across market capitalization, and to control for alternative anomalies and risks. Cost growth is strongly associated with deterioration in a firm’s future profitability, which investors appear failing to incorporate into valuation. In addition, the …

Does Latitude Hurt While Longitude Kills? Geographical And Temporal Separation In A Large Scale Software Development Project, Patrick Wagstrom, Subhajit Datta

Research Collection School Of Computing and Information Systems

Distributed software development allows firms to leverage cost advantages and place work near centers of competency. This distribution comes at a cost -- distributed teams face challenges from differing cultures, skill levels, and a lack of shared working hours. In this paper we examine whether and how geographic and temporal separation in a large scale distributed software development influences developer interactions. We mine the work item trackers for a large commercial software project with a globally distributed development team. We examine both the time to respond and the propensity of individuals to respond and find that when taken together, geographic …

Paths Of Influence For Innovations In Financial Is And Technology Ecosystems, Jun Liu, Robert John Kauffman, Dan Ma Jun 2014

Paths Of Influence For Innovations In Financial Is And Technology Ecosystems, Jun Liu, Robert John Kauffman, Dan Ma

Research Collection School Of Computing and Information Systems

Predicting technological innovations in financial information systems (IS) and technology ecosystems has been challenging for technology forecasters and industry analysts due to their underlying complexity. Technology-based financial innovations over the past four decades, such as programmed trading in the 1980s, risk-adjusted return on capital-based financial risk management systems in the 1990s, high-frequency trading and Internet banking in 2000s, and now mobile payments in the 2010s, have all led to transformations in the financial services industry. What basis can be identified to predict such new innovations? And what areas of financial services will they affect? This study applies the technology ecosystem …
