Dynamic Advantage, Stephen Richard Wyatt

Dissertations and Theses Collection (Open Access)

Approximately eighty per cent of the value of most listed firms is driven by expectations of their future earning stream. Yet past and current period results are decreasingly relevant as indicators of future performance as the speed of change in business, technology, trends and markets increases. For many companies instability is the new norm, agility and preparing for future changes are essential capabilities.

This research, drawing on experiences of 30 global corporations, shows that far from being giants with slow reactions, several global corporations are able to leverage their extensive networks and their participation in a wide diversity of market …

On The Edge Of Disruption, David K. C. Lee

Research Collection Lee Kong Chian School Of Business

The financial system is on the verge of massive disruption. Innovative competitors operating on sleek business models and offering new alternative services are entering at the bottom of the market, where gross margins are low and latent demand is high. As these new entrants scale and progress through higher market segments, they will erode incumbent pricing power.

Testing For Multiple Bubbles: Historical Episodes Of Exuberance And Collapse In The S&P 500, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

Recent work on econometric detection mechanisms has shown the effectiveness of recursive procedures in identifying and dating financial bubbles in real time. These procedures are useful as warning alerts in surveillance strategies conducted by central banks and fiscal regulators with real-time data. Use of these methods over long historical periods presents a more serious econometric challenge due to the complexity of the nonlinear structure and break mechanisms that are inherent in multiple-bubble phenomena within the same sample period. To meet this challenge, this article develops a new recursive flexible window method that is better suited for practical implementation with long …

Intelligshop: Enabling Intelligent Shopping In Malls Through Location-Based Augmented Reality, Aditi Adhikari, Vincent W. Zheng, Hong Cao, Miao Lin, Yuan Fang, Kevin Chen-Chuan Chang

Research Collection School Of Computing and Information Systems

Shopping experience is important for both citizens and tourists. We present IntelligShop, a novel location-based augmented reality application that supports intelligent shopping experience in malls. As the key functionality, IntelligShop provides an augmented reality interface-people can simply use ubiquitous smartphones to face mall retailers, then IntelligShop will automatically recognize the retailers and fetch their online reviews from various sources (including blogs, forums and publicly accessible social media) to display on the phones. Technically, IntelligShop addresses two challenging data mining problems, including robust feature learning to support heterogeneous smartphones in localization and learning to query for automatically gathering the retailer content …

Testing For Multiple Bubbles: Limit Theory Of Real-Time Detectors, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

This article provides the limit theory of real-time dating algorithms for bubble detection that were suggested in Phillips, Wu, and Yu (PWY; International Economic Review 52 [2011], 201-26) and in a companion paper by the present authors (Phillips, Shi, and Yu, 2015; PSY; International Economic Review 56 [2015a], 1099-1134. Bubbles are modeled using mildly explosive bubble episodes that are embedded within longer periods where the data evolve as a stochastic trend, thereby capturing normal market behavior as well as exuberance and collapse. Both the PWY and PSY estimates rely on recursive right-tailed unit root tests (each with a different recursive …

Cointegration Of Matched Home Purchases And Rental Price Indexes: Evidence From Singapore, Badi H. Baltagi, Jing Li

Research Collection School Of Economics

This paper exploits the homogeneity feature of the Singapore private residential condominium market and constructs matched home purchase price and rental price series using the repeated sales method. These matched series allow us to conduct time series analysis to examine the long-term present value relationship in the housing market. Three key findings are obtained. First, we fail to establish a cointegrating relationship between the home purchase price and rental price based on nationally estimated indexes. Second, area-specific indexes demonstrate strong cross-correlations, invalidating the use of first generation panel unit root tests that ignore these cross-correlations. Third, Pesaran's CIPS test indicates …

Inquiring Into Activist Publics In Chronic Environmental Issues: Use Of The Mutual Gains Approach For Breaking A Deadlock, Soojin Kim, Jeong-Nam Kim, Laishan Tam, Gwang Tae Kim

Research Collection Lee Kong Chian School Of Business

This study aims to understand different publics’ communicative behaviors for problem solving surrounding an oil spill issue in Korea. Specifically, it explores the differences between chronic activists and other types of publics who were affected by this chronic environmental issue. A total of 24 interviews were conducted, from which five different types of publics were identified. The findings suggest that the majority of activists who are currently working on the issue are closed-chronic activists, which are slightly different from Ni and Kim’s findings on chronic activists’ communicative behaviors. Interviews were also conducted with five communication experts to propose viable conflict …

A Risk- And Complexity-Rating Framework For Investment Products, Benedict S. K. Koh, Francis Koh, David K. C. Lee, Kian Guan Lim, David Ng, Kok Fai Phoon

Research Collection Lee Kong Chian School Of Business

Many investors who bought such investments as Lehman Brothers’ minibonds did not understand the products’ complicated features. This fact suggests that if the inherent risk and complexity of products’ structure are not clearly understood by investors, they will be unable to make informed decisions. Some practitioners have recently attempted to calibrate product complexity. The authors propose a framework for classifying investment product risk and complexity separately with a list of factors that contribute to these attributes. They demonstrate the framework’s simplicity and usefulness in helping investors make informed decisions, showing that it can be used to calibrate a variety of …

How Kinetic Property Shapes Novelty Perceptions, Junghan Kim, Arun Lakshmanan

Research Collection Lee Kong Chian School Of Business

This article demonstrates a new substantive finding: that kinetic property in advertising, defined as direction changes in the paths of moving on-screen ad elements, enhances consumer judgments of product novelty. Across six studies, the authors first outline an inference-based theory as to why the novelty-enhancing effect of kinetic property manifests: kinetic property generates impressions of how visually lively an ad is, which leads to inferences of product atypicality and, consequently, higher novelty judgments. Second, they demonstrate boundary conditions by showing that (1) the positive effect for kinetic property is evident with incremental (and not radical) innovations, (2) the effect dissipates …

The Bright Side Of Political Uncertainty: The Case Of R&D, Julian Atanassov, Brandon Julio, Tiecheng Leng

Research Collection Lee Kong Chian School Of Business

We examine the relationship between political uncertainty and R&D investment by exploiting the timing of U.S. gubernatorial elections as a source of plausibly exogenous variation in uncertainty. In contrast to the literature documenting negative effects of political uncertainty on real investment, we find that uncertainty over government policy encourages firm-level R&D. Firms increase R&D investments by an average of 4.6% in election years relative to non-election years. The uncertainty effect is stronger in hotly contested elections, in politically sensitive and hard-to-innovate industries, and in firms subject to higher growth options and greater product market competition. Our findings suggest that, as …

The Brief Aggression Questionnaire: Reliability, Validity, And Structure, Gregory D. Webster, C. Nathan Dewall, Richard S. Pond, Timothy Deckman, Peter K. Jonason, Bonnie M. Le, Austin Lee Nichols, Tatiana Orozco Schember, Laura C. Crysel, Benjamin S. Crosier, C. Veronica Smith, Elizabeth Layne Paddock

Research Collection Lee Kong Chian School Of Business

In contexts that increasingly demand brief self-report measures (e.g., experience sampling, longitudinal and field studies), researchers seek succinct surveys that maintain reliability and validity. One such measure is the 12-item Brief Aggression Questionnaire (BAQ; Webster et al., 2014), which uses 4 3-item subscales: Physical Aggression, Verbal Aggression, Anger, and Hostility. Although prior work suggests the BAQ's scores are reliable and valid, we addressed some lingering concerns. Across 3 studies (N = 1,279), we found that the BAQ had a 4-factor structure, possessed long-term test–retest reliability across 12 weeks, predicted differences in behavioral aggression over time in a laboratory experiment, …

Competition Of The Informed: Does The Presence Of Short Sellers Affect Insider Selling?, Massimo Massa, Wenlan Qian, Weibiao Xu, Hong Zhang

Research Collection Lee Kong Chian School Of Business

We study how the presence of short sellers affects the incentives of the insiders to trade on negative information. We show it induces insiders to sell more (shares from their existing stakes) and trade faster to preempt the potential competition from short sellers. An experiment and instrumental variable analysis confirm this causal relationship. The effects are stronger for "opportunistic" (i.e., more informed) insider trades and when short sellers' attention is high. Return predictability of insider sales only occurs in stocks with high short-selling potential, suggesting that short sellers indirectly enhance the speed of information dissemination by accelerating trading by insiders. …

New Approach To Density Estimation And Application To Value-At-Risk, Kian Guan Lim, Hao Cheng, Nelson K. L. Yap

Research Collection Lee Kong Chian School Of Business

The key contribution in this paper is to provide a new approach in estimating the physical distribution of the underlying asset return by using a quadratic Radon-Nikodym derivative function. The latter function transforms a fitted Variance Gamma risk-neutral distribution that is obtained from traded option prices. The generality of the VG distribution helps to avoid unnecessary mis-specification bias. The estimated empirical distribution is then used to find the risk measure of VaR. We show that possible underestimation of VaR risk using existing methods is largely not due to VaR itself but perhaps due to mis-specification errors which we minimize in …

Institutional Trading During A Wave Of Corporate Scandals: 'Perfect Payday'?, Gennaro Bernile, Johan Sulaeman, Qin Wang

Research Collection Lee Kong Chian School Of Business

This paper examines the role of institutional trading during the option backdating scandal of 2006-2007. Unlike their inability to anticipate other corporate events, institutional investors as a group display negative abnormal trading imbalances (i.e., buy minus sell volumes) in anticipation of firm-specific backdating exposures. Consistent with informed trading, the underlying trades earn positive abnormal short- and long-term profits. Moreover, the negative abnormal imbalances are larger in magnitude when backdating is likely a more severe issue. Local institutions, in particular, display negative trading imbalances earlier in event-time and earn consistently higher trading profits than non-local institutions. Although we find some evidence …

Navigating The “Patent-Cliff”: The Role Of Corporate Real Estate In The Life Science Industry, Clarence Goh

Research Collection School Of Accountancy

The Life Science industry is standing on the edge of a “patent cliff.” In 2015, the world’s biggest pharmaceutical firms stand to lose up to US$47.5 billion in revenues from the expiry of the patents of some of their biggest blockbuster drugs. For example, Celebrex – an arthritis drug which contributed almost US$3 billion to Pfizer’s revenues in 2014 – is set to see its patent expire later this year, opening it up to competition from “generic” alternatives which are often sold at much cheaper prices.

Innovations In Financial Is And Technology Ecosystems: High-Frequency Trading Systems In The Equity Market, Robert J. Kauffman, Jun Liu, Dan Ma

Research Collection School Of Computing and Information Systems

Technology-based financial innovations over the past four decades have led to transformations in the financial markets. Understanding technological innovations in financial information systems (IS) and technologies has been challenging for technology consultants and financial industry practitioners due to the underlying complexities though. In this article, we propose an ecosystem analysis approach by extending the technology ecosystem paths of influence model (Adomavicius et al., 2008a) to incorporate stakeholder actions, considering both supply-side and demand-side forces for technological change. Our ecosystem model brings together three original core elements: technology components, technology-based services, and technology-supported business infrastructures. We also contribute a fourth new …

Enhancing Students' Learning Process Through Interactive Digital Media: New Opportunities For Collaborative Learning, Benjamin Gan, Thomas Menkhoff, Richard R. Smith

Research Collection School Of Computing and Information Systems

In this paper, we describe and review several examples of web technology-enabled teaching and learning approaches at undergraduate level in an Asian institution of higher learning. We begin by reporting on experiences made in the context of an iPad-enabled mobile learning project conducted during a Knowl- edge Management course (excursion) in support of the university’s technology-enabled learning vision. This is followed by reflections on the deployment of a collaborative social learning platform website (Edmodo), wiki- and web page-creation tools (Google Site), animated videos, etc. in elective courses on leadership and human capital management. Finally, we describe a proven project-based learning …

Gender Research In Amj: An Overview Of Five Decades Of Empirical Research And Calls To Action, Aparna Joshi, Brett Neely, Cynthia Emrich, Dorothy Griffiths, Gerard George

Research Collection Lee Kong Chian School Of Business

Fifteen years into the 21st century, gender equality appears to be at the forefront of the global humanitarian agenda. As a co-recipient of the 2014 Nobel Peace Prize, Malala Yousafzai became a symbol for the rights of women and girls to obtain an education. In the same year, the United Nations launched the “HeForShe” campaign, which views men and boys as advocates and stakeholders in the campaign for gender equality around the world. Globally, equitable access to education and employment has been recognized as not only a “women’s issue” but as a human rights issue (UN Women, 2014).

Trading Costs On The Stock Exchange Of Thailand, Nattawut Jenwittayaroje, Charlie Charoenwong, David K. Ding, Yung Chiang Yang

Research Collection Lee Kong Chian School Of Business

This study examines the components of trading costs incurred in trading large and liquid stocks listed on the Stock Exchange of Thailand. We find that aggressive orders pay an immediacy price measured by price impact, whereas executed passive orders gain the immediacy price. We also find a sizable opportunity cost from the unexecuted portion of a limit order that more than offsets the benefit obtained from the partial fulfillment of the order. The total trading cost, which includes price impact and opportunity cost, is positively related to order size and stock price volatility, but negatively associated with firm size, stock …

Incorporating Microblogging (“Tweeting”) In Higher Education: Lessons Learnt In A Knowledge Management Course, Thomas Menkhoff, Yue Wah Chua, Magnus L. Bengtsson, C. Jason Woodard, Benjamin Gan

Research Collection Lee Kong Chian School Of Business

This paper features a competency-enhancing social networking application which provides a solution for the dilemma of non-participating (non-engaged) students in class: ‘pedagogical tweeting’. Twitter’s micro-blogging service enables both instructors and students to send and read messages (tweets) of up to 140 characters, incl. links to blogs, web pages, photos, videos, etc. As Twitter can be accessed from a website, via applications on PC/Mac, iPhone, Android phones, etc., it represents an effective tool to engage students, e.g. by taking up questions during in-class and out-of-class discussions or by providing advice on assignments etc. Students in turn can generate their own learning …

Endogenous Network Effects, Platform Pricing And Market Liquidity, Mei Lin, Ruhai Wu, Wen Zhou

Research Collection School Of Computing and Information Systems

This paper examines a monopoly platform's two-sided pricing strategies in a setting with seller competition, which gives rise to not only positive cross-side network effects between buyers and sellers, but also a negative same-side network effect among sellers. We show that platform pricing depends crucially on the characteristics associated with market liquidity, which contrasts with the previous studies that point to the two sides' relative demand elasticities and/or network effects. A market is said to be more liquid when it has less friction, resulting in a larger total surplus for the platform economy and hence greater equilibrium entry on both …
