Value Relevance Of Blog Visibility, Nan Hu, Ling Liu, Arindam Tripathy, Lee J. Yao Dec 2011

Value Relevance Of Blog Visibility, Nan Hu, Ling Liu, Arindam Tripathy, Lee J. Yao

Research Collection School Of Computing and Information Systems

This study empirically examines the effect of a non-traditional information source, namely a firm's blog visibility on the capital market valuation of firms. After controlling for earnings, book value of equity and other value relevant variables, such as traditional media exposure, R&D spending, and advertising expense, we find a positive association between a firm's blog visibility and its capital market valuation. In addition, we find blog visibility Grange causes trading, not vice versa. Our findings indicate that non-traditional information sources such as blogs help disseminate information and influence consumers' investment decisions by capturing their attention.

The Valuation Of User-Generated Content: A Structural, Stylistic And Semantic Analysis Of Online Reviews, Noi Sian Koh Dec 2011

The Valuation Of User-Generated Content: A Structural, Stylistic And Semantic Analysis Of Online Reviews, Noi Sian Koh

Dissertations and Theses Collection (Open Access)

The ability and ease for users to create and publish content has provided vast amount of online product reviews. However, the amount of data is overwhelmingly large and unstructured, making information difficult to quantify. This creates challenge in understanding how online reviews affect consumers’ purchase decisions. In my dissertation, I explore the structural, stylistic and semantic content of online reviews. Firstly, I present a measurement that quantifies sentiments with respect to a multi-point scale and conduct a systematic study on the impact of online reviews on product sales. Using the sentiment metrics generated, I estimate the weight that customers place …

Corporate Philanthropy And Corporate Financial Performance: The Roles Of Social Response And Political Access, Heli Wang, Cuili Qian Dec 2011

Corporate Philanthropy And Corporate Financial Performance: The Roles Of Social Response And Political Access, Heli Wang, Cuili Qian

Research Collection Lee Kong Chian School Of Business

Corporate philanthropy is expected to positively affect firm financial performance because it helps firms gain sociopolitical legitimacy, which enables them to elicit positive stakeholder responses and to gain political access. The positive philanthropy-performance relationship is stronger for firms with greater public visibility and for those with better past performance, as philanthropy by these firms gains more positive stakeholder responses. Firms that are not government-owned or politically well connected were shown to benefit more from philanthropy, as gaining political resources is more critical for such firms. Empirical analyses using data on Chinese firms listed on stock exchanges from 2001 to 2006 …

Stochastic Capacity Investment And Flexible Vs. Dedicated Technology Choice In Imperfect Capital Markets, Onur Boyabatli, L. Bertil Toktay Dec 2011

Stochastic Capacity Investment And Flexible Vs. Dedicated Technology Choice In Imperfect Capital Markets, Onur Boyabatli, L. Bertil Toktay

Research Collection Lee Kong Chian School Of Business

This paper analyzes the impact of endogenous credit terms under capital market imperfections in a capacity investment setting. We model a monopolist firm that decides on its technology choice (flexible versus dedicated) and capacity level under demand uncertainty. Differing from the majority of the stochastic capacity investment literature, we assume that the firm is budget constrained and can relax its budget constraint by borrowing from a creditor. The creditor offers technology-specific loan contracts to the firm, after which the firm makes its technology choice and subsequent decisions. Capital market imperfections impose financing frictions on the firm. Our analysis contributes to …

Longevity Risk Management In Singapore's National Pension System, Joelle H. Y. Fong, Olivia S. Mitchell, Benedict S. K. Koh Dec 2011

Longevity Risk Management In Singapore's National Pension System, Joelle H. Y. Fong, Olivia S. Mitchell, Benedict S. K. Koh

Research Collection Lee Kong Chian School Of Business

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore’s Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public sector provider for such annuities. This article evaluates the money’s worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market.

Social Networks And The Desire To Save Face: A Case From Singapore, Michael A. Netzley, Akanksha Rath Dec 2011

Social Networks And The Desire To Save Face: A Case From Singapore, Michael A. Netzley, Akanksha Rath

Research Collection Lee Kong Chian School Of Business

For five years, corporate communication undergraduates have maintained a wiki as a final course and community service project. Using Web 2.0 platforms to crowdsource and curate content, they learn to employ online communications for work purposes. When the course was launched in 2007, the dominant social media narrative invited educators to embrace a technological optimism with sub-themes of open communication, sharing, and co-creation. By 2011, student feedback had compelled the instructor to consider the limits of technological optimism and revise the course. Specifically, Singaporean students have displayed a need to save face online, which has led to a localized teaching …

Assessing The Impact Of Recommendation Agents On On-Line Consumer Unplanned Purchase Behavior, R. Eric Hostler, Victoria Y. Yoon, Zhiling Guo, Tor Guimaraes, Guisseppi Forgionne Dec 2011

Assessing The Impact Of Recommendation Agents On On-Line Consumer Unplanned Purchase Behavior, R. Eric Hostler, Victoria Y. Yoon, Zhiling Guo, Tor Guimaraes, Guisseppi Forgionne

Research Collection School Of Computing and Information Systems

Recommendation agents (RAs) have been used by many Internet businesses such as Amazon and Netflix. However, few authors have studied how consumer behavior is affected by those that make suggestions to online consumers based on their recent shopping behavior. Fewer still have examined the role that RAs play in influencing impulse purchasing decisions online. Our study developed a theoretical model to illustrate the impact of RAs on online consumer behavior. The model was tested through an online shopping simulation which used a collaborative filtering based product RA. Particular attention was paid to the effects of an RA on consumer behavior; …

A Multiechelon Inventory Problem With Secondary Market Sales, Alexandar Angelus Dec 2011

A Multiechelon Inventory Problem With Secondary Market Sales, Alexandar Angelus

Research Collection Lee Kong Chian School Of Business

We consider a finite-horizon, multiechelon inventory system in which the surplus of stock can be sold (i.e., disposed) in the secondary markets at each stage in the system. What are called nested echelon order-up-to policies are shown to be optimal for jointly managing inventory replenishments and secondary market sales. Under a general restriction on model parameters, we establish that it is optimal not to both sell off excess stock and replenish inventory. Secondary market sales complicate the structure of the system, so that the classical Clark and Scarf echelon reformulation no longer allows for the decomposition of the objective function …

Technical Note: Cellular Bucket Brigades, Yun Fong Lim Dec 2011

Technical Note: Cellular Bucket Brigades, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

Workers in a bucket brigade production system perform unproductive travel when they walk to get more work from their colleagues. We introduce a new design of bucket brigades to reduce unproductive travel. Under the new design, each worker works on one side of an aisle when he proceeds in one direction and works on the other side when he proceeds in the reverse direction. We propose simple rules for workers to share work under the new design and find a sufficient condition for the system to self-balance. Numerical examples suggest that the improvement in throughput by the new design can …

Charting Your Financial Goals, Benedict Koh Dec 2011

Charting Your Financial Goals, Benedict Koh

Research Collection Lee Kong Chian School Of Business

Every one of us has financial goals but not many of us know how to go about achieving them. We often lack investment knowledge or expertise to design an investment plan that optimises our savings. Consequently, we adopt the default approach of leaving all our savings in bank deposits. By doing so, we have already made an asset allocation decision, one that is very conservative. Over time, we soon realise that this conservative investment plan is simply not working as our savings are not compounding fast enough to keep up with inflation. We need to invest more wisely so that …

Modeling Multichannel Home Video Demand In The U.S. Motion Picture Industry, Anirban Mukherjee, Vrinda Kadiyali Dec 2011

Modeling Multichannel Home Video Demand In The U.S. Motion Picture Industry, Anirban Mukherjee, Vrinda Kadiyali

Research Collection Lee Kong Chian School Of Business

The U.S. motion picture industry has become increasingly reliant on posttheatrical channel profits. Two often-cited drivers of these profits are cross-channel substitution among posttheatrical channels and seasonality in consumer preferences for any movie. The authors use a differentiated products version of the multiplicative competitive interaction model to investigate these two phenomena. They estimate the model using data from 2000 and 2001 on two posttheatrical channels in the U.S. market: purchase and rental home viewing channels. Contrary to expectations based on business press commentary, after controlling for seasonality and movie attributes, the authors find low cross-channel price and availability elasticity for …

Dealing With The Threats Inherent In Unproctored Internet Testing Of Cognitive Ability: Results From A Large-Scale Operational Test Program, Filip Lievens, Eugene Burke Dec 2011

Dealing With The Threats Inherent In Unproctored Internet Testing Of Cognitive Ability: Results From A Large-Scale Operational Test Program, Filip Lievens, Eugene Burke

Research Collection Lee Kong Chian School Of Business

There is little information available about operational systems of unproctored Internet testing (UIT) of cognitive ability and how they deal with the threats inherent in UIT. This descriptive study provides a much-needed empirical examination of a large-scale operational UIT system of cognitive ability that implemented test design and verification testing for increasing test security and honest responding. Test security evaluations showed item exposure and test overlap rates were acceptable. Aberrant score evaluations revealed that negative score change (higher unproctored scores than proctored ones) was negligible. Implications for UIT research are discussed.

From Primordial Soup To Platform-Based Competition: Exploring The Emergence Of Products, Systems, And Platforms, C. Jason Woodard, Eric K. Clemons Dec 2011

From Primordial Soup To Platform-Based Competition: Exploring The Emergence Of Products, Systems, And Platforms, C. Jason Woodard, Eric K. Clemons

Research Collection School Of Computing and Information Systems

We use an agent-based NK model to explore the conditions under which standard platforms emerge among competing products. Our findings were inconclusive. We find that the usual Darwinian conditions needed for the emergence of complexity are sufficient to yield a limited reliance upon platforms with a core of common components, simply because evolution causes the population to converge on a set of products that contain combinations that "work well," yielding what we call "coincidental platform emergence." Economies of scale yield more use of common components, or "production platform emergence." Positive participation externalities initially induce the highest degree of platform emergence …

Four Perspectives On Architectural Strategy, C. Jason Woodard, Joel West Dec 2011

Four Perspectives On Architectural Strategy, C. Jason Woodard, Joel West

Research Collection School Of Computing and Information Systems

A recurring theme in the literature on technology and organizations is the concept of mirroring, which posits a duality between technological and organizational design decisions. In this paper we highlight a second, orthogonal duality between components and interfaces: designers of both products and organizations must decide what information to hide within component boundaries and what to expose to other designers. Although the component-interface duality appears in many settings, it presents especially vexing strategic challenges in the design and production of complex digital artifacts. We present a typology of four interlinked perspectives on these kinds of strategic design problems, and discuss …

Content Contribution Under Revenue Sharing And Reputation Concern In Social Media: The Case Of Youtube, Qian Tang, Bin Gu, Andrew B. Whinston Dec 2011

Content Contribution Under Revenue Sharing And Reputation Concern In Social Media: The Case Of Youtube, Qian Tang, Bin Gu, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

A key feature of social media is that it allows individuals and businesses to contribute contents for public viewing. However, little is known about how content providers derive payoffs from such activities. In this study, we build a dynamic structural model to recover the utility function for content providers. Our model distinguishes short-term payoffs based on ad revenue sharing from long-term payoffs driven by content providers’ reputation. The model was estimated using a panel data of 914 top 1000 providers and 381 randomly selected providers on YouTube from Jun 7th, 2010, to Aug 7th, 2011. The two different sets of …

Agile Innovation Management, Arcot Desai Narasimhalu

Research Collection School Of Computing and Information Systems

The volume and velocity of innovations are on the increase resulting in increased pressures on every company for attaining, retaining and increasing its market leadership. Many companies need to retool their innovation management processes to address two agility related objectives in order to survive and grow in such a rapidly changing innovation environment. The first objective would be the ability to assemble an innovation team within the shortest possible time. This can only be satisfied by companies that are capable of forming innovation teams rather quickly. The related second objective would be to reduce the I2M (Idea to Market) cycle …

A competent tax system should meet an economy's fiscal needs, but that cannot exist without a tax design that understands, pre-empts, and ultimately shapes human behaviours. Drawing from the UK's Mirrlees Review, Richard Blundell, research director at the London-based Institute of Fiscal Studies, delivered a lecture at Singapore Management University's School of Economics on the principles of the tax reform, and the challenges that await governments in formulating a coherent and economically efficient tax structure.

Singapore: Building A Future Without Cheap Oil, Knowledge@Smu

Knowledge@SMU

Singapore’s past success at building a world-class economy launched on the back of a hugely successful oil refining and trading system could count for little as it confronts the threats of the increasing scarcity and cost of energy supply. In a book commissioned by the International Trading Institute@SMU, 'Singapore, The Energy Economy: From The First Refinery To The End Of Cheap Oil, 1960 to 2010', author Ng Weng Hoong argues that Singapore’s single-minded focus on growing the economy while assuming that the supply of energy and natural resources will always be cheap and plentiful leaves the city-state increasingly vulnerable and …

Knowledge@SMU

Social networks offer up a goldmine of information. Save for privacy concerns, it has never before been easier for researchers to understand the needs and wants of their subjects or to examine links between the likes and dislikes of connected individuals. Going beyond the report of human quirks over the internet, however, web 2.0 data has practical uses too, especially for professionals in finance and marketing. At the 3rd International Conference on Social Informatics, hosted by SMU's School of Information Systems, academics discussed the hurdles and real-world benefits of data mining.

Supporting Global Metals Markets: The Role Of The London Metals Exchange, Knowledge@Smu

Knowledge@SMU

Most people would expect automobiles and electronics, comprised of many important metal parts, to be sold at relatively stable prices. Little do consumers appreciate, however, the backend market mechanisms that keep these prices stable. A prospective car buyer does not have to monitor his or her dream car's daily price fluctuations, for example, precisely because the parts that go into its manufacture maintain steady prices. This is, in part, the doing of metal exchanges that regulate the demand and supply of metals. Liz Milan, managing director of the London Metals Exchange Asia, explained this and more at a seminar organised …

In Search Of A Different Accounting Graduate: Entry-Point Determinants Of Students’ Performance In An Undergraduate Accountancy Degree Programme In Singapore, Poh Sun Seow, Pan, Gary, Siok Wan Joanne Tay

Research Collection School Of Accountancy

This study investigates the association of prior academic achievement, admission interview, critical thinking, mathematical aptitude, gender and age with successful academic performance in an undergraduate accountancy degree programme at a Singapore university. The purpose of revisiting the determinants of academic performance is twofold: firstly, university accounting education in Singapore has changed greatly since Koh and Koh’s earlier study (1999), so this study examines if determinants previously identified as significant continue to be so in the new setting; secondly, the study tests the usefulness of admission interview in identifying applicants who achieve subsequent academic success. All the data on students’ performance …
