How Can Substitution And Complementarity Effects Be Leveraged For Broadband Internet Services Strategy?, Gwangjae Jung, Young Soo Kim, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

With growth in mobile Internet services, the relationship between mobile and fixed broadband has become an issue in telecom firm strategy. Previous research focused on aggregate penetration for mobile and fixed broadband services. Our research analyzes the economic relationship between mobile and fixed broadband services at the household level, as a basis for how senior managers should rethink their strategy approach. Using data on broadband services subscriptions, we examine how changes that occur for mobile broadband services bandwidth (MBB) affect changes in fixed broadband bandwidth (FBB) services subscriptions, inclusive of new subscriptions - and vice versa. We explore the different …

Strategic Decision Support System Using Heuristic Algorithm For Practical Outlet Zones Allocation To Dealers In A Beer Supply Distribution Network, Michelle Lee Fong Cheong

Research Collection School Of Computing and Information Systems

We consider a two-echelon beer supply distribution network with the brewer replenishing the dealers and the dealers serving the outlet zones directly, for multiple product types. The allocation of the outlet zones to the dealers will determine the quantity of products the brewer replenishes each dealer, which will in turn impact the total warehousing and transportation costs. The non-linear optimization model formulated is difficult to solve to optimality, and the model itself does not include practical business considerations in the distribution business. A heuristics algorithm is designed and easily implemented using spreadsheets with Visual Basic programming to effectively and efficiently …

Online Portfolio Selection: A Survey, Bin Li, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

Online portfolio selection is a fundamental problem in computational finance, which has been extensively studied across several research communities, including finance, statistics, artificial intelligence, machine learning, and data mining. This article aims to provide a comprehensive survey and a structural understanding of online portfolio selection techniques published in the literature. From an online machine learning perspective, we first formulate online portfolio selection as a sequential decision problem, and then we survey a variety of state-of-the-art approaches, which are grouped into several major categories, including benchmarks, Follow-the-Winner approaches, Follow-the-Loser approaches, Pattern-Matching--based approaches, and Meta-Learning Algorithms. In addition to the problem formulation …

How Can Consumer Preferences Be Leveraged For Targeted Upselling In Cable Tv Services?, Bing Tian Dai

Research Collection School Of Computing and Information Systems

Internet TV has attracted a significant amount of attention from the conventional cable TV service providers, by providing customized TV programs at preferred time slots. The cable TV service providers are seeking to retain their customers by giving them a better experience: by understanding their customers’ preferences and upselling them the right products to cater to their interests. It is not easy to understand customer preferences though, since customers are not able to watch channels to which they have not subscribed. This makes it difficult to predict what they will like to watch, as a result. In this paper, I …

Running And Chasing: The Competition Between Paid Search Marketing And Search Engine Optimization, Kai Li, Mei Lin, Zhangxi Lin, Bo Xing

Research Collection School Of Computing and Information Systems

As search engine is leading the revenue growth in online marketing field, the competition of search engine marketing between paid search marketing (PSM) by search engine providers (SEPs), and search engine optimization (SEO) provided by search engine optimization firms, is white-hot. While PSM is simply for advertisers to buy the top ranks in sponsored links, SEO tries to optimize advertisers' websites by free-riding search engine's organic searching results. This study aims to investigate this competition by analytical modeling regarding organic search quality. We focus on sustainability conditions of SEO firms, investment analysis of SEO firms, and profit analysis of SEP. …

Revisiting The Determinants Of Students' Performance In An Undergraduate Accountancy Degree Programme In Singapore, Poh Sun Seow, Gary Pan, Joanne Siok Wan Tay

Research Collection School Of Accountancy

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

Is The Decline In The Information Content Of Earnings Following Restatements Short-Lived?, Xia Chen, Qiang Cheng, Alvis K. Lo

Research Collection School Of Accountancy

Prior research finds that the decline in the information content of earnings after restatement announcements is short-lived and the earnings response coefficient (ERC) bounces back after three quarters. We re-examine this issue using a more recent and comprehensive sample of restatements. We find that material restatement firms experience a significant decrease in the ERC over a prolonged period—close to three years after restatement announcements. In contrast, other restatement firms experience a decline in the ERC for only one quarter. We further find that among material restatement firms, those that are subject to more credibility concerns and those that do not …

Media Coverage And Firm Valuation: Evidence From China, Jiwei Wang, Kangtao Ye

Research Collection School Of Accountancy

Drawing on both a managerial discipline perspective and an information intermediary perspective, we explore how media coverage of a firm’s controlling shareholder influences firm valuation in corporate China. Using 366 listed family firms in China from 2003 to 2006, we find that firms in which controlling shareholders receive more neutral media reports enjoy higher valuation, whereas negative media reports on controlling shareholders impose adverse effects on firm valuation. Interestingly, favorable media coverage of the controlling shareholders does not enhance firm value. Further analyses reveal that ownership structure and audit quality moderate the relationship between media coverage and firm valuation. Our …

Do Managers Use Meeting Analyst Forecasts To Signal Private Information? Evidence From Patent Citations, Katherine Gunny, Tracey Chunqi Zhang

Research Collection School Of Accountancy

This study examines whether firms manage earnings to meet analyst forecasts to signal superior future performance. Prior research finds that firms use earnings management to just meet analyst forecasts and that these firms have a positive association with future performance (Bartov et al., 2002). There are two potential explanations for the positive association – signaling and attaining benefits that allow for better future performance (i.e., the real benefits explanation). Prior studies cannot provide evidence of signaling because they do not control for the real benefits explanation. Our research design enables us to control for the real benefits explanation because we …

Loan Loss Reserves, Regulatory Capital, And Bank Failures: Evidence From The Recent Economic Crisis, Tee Yong Jeffrey Ng, Sugata Roychowdhury

Research Collection School Of Accountancy

Regulatory capital guidelines allow for loan loss reserves to be added back as capital. The evidence in this paper suggests that the influence of loan loss reserves added back as regulatory capital (hereafter referred to as “add-backs”) on bank risk cannot be explained by either economic principles underlying the notion of capital, or accounting principles underlying the recording of reserves. Specifically, we observe that in sharp contrast to the economic notion of capital as a buffer against bank failure risk, add-backs are positively associated with the risk of bank failure during the recent economic crisis. Further the positive association of …

Seeing Is Believing: Do Analysts Benefit From Site Visits, Qiang Cheng, Fei Du, Xin Wang, Yutao Wang

Research Collection School Of Accountancy

Using the unique data of analysts’ site visits to Chinese listed companies, we examine whether and how analysts’ site visits help improve their forecast performance. We find that the forecast accuracy of analysts improves after they visit the target firms and this improvement still holds after controlling for the concurrent change in the forecast accuracy of analysts who do not conduct site visits. Such an improvement is more pronounced for firms with better corporate governance; for more experienced analysts; and for firms with higher earnings volatility. Moreover, the improvement of forecast accuracy is less pronounced when current site visits are …

Coordinating The Processes Of Resource Enrichment And Capability Deployment: Lessons From It Implementation At A Medium-Sized Accounting Firm, Gary Pan, Sayyen Teoh, Poh Sun Seow

Research Collection School Of Accountancy

The purpose of this paper has been to address the research question of how are the processes of resource enrichment and capability deployment coordinated during information technology (IT) implementation at a small- and medium-sized accounting firm (SMAF)? Increasingly, organizations need to respond to a wide range of IT-based opportunities and pressures. The situation is no different in an accounting firm. Many accounting practitioners have advocated investment in IT to improve accounting firms’ productivity. To date, there are many instances of how IT has radically transformed the nature of accounting practice. Nevertheless, little is known about how IT capability is developed …

The authors offer an in-depth discussion of the possibilities and pitfalls of pursuing social innovation in the context of international development.

Signaling The Green Sell: The Influence Of Eco-Label Source, Argument Specificity, And Product Involvement On Consumer Trust, Lucy Atkinson, Sonny Rosenthal

Research Collection College of Integrative Studies

Consumers cannot verify green attributes directly and must rely on such signals as eco-labels to authenticate claims. Using signaling theory, this study explored which aspects of eco-label design yield more positive effects. The study uses a 2 (argument specificity: specific versus general) × 2 (label source: government versus corporate) × 2 (product involvement: low versus high) experimental design (n = 233). Specific arguments consistently yield greater eco-label trust and positive attitudes toward the product and label source, but only with low-involvement products is source important, with corporate labels yielding more positive attitudes. Findings are discussed in terms of theoretical and …

Bank Valuation In Malaysia: An Empirical Comparison Of Conventional And Interest-Free (Islamic) Banking Models, Charlie Charoenwong, Ramin Cooper Maysami, David K. Ding

Research Collection Lee Kong Chian School Of Business

Islamic banking, according to institute for Islamic Banking and Insurance "refers to a system of banking or banking activity that is consistent with the principles of the Shari'ah (Islamic rulings) and its practical application through the development of Islamic economics. Shari'ah prohibits the payment or acceptance of interest charges (riba) for the lending and accepting of money, as well as carrying out trade and other activities that provide goods or services considered contrary to its principles." The thrust of the current article is to examine the underlying factors and variables that guide the valuation of a sample of five Malaysian …

Perspective-Taking And Willingness To Engage In Intergroup Contact, Cynthia S. Wang, Kenneth Tai, Gillian Ku, Adam D. Galinsky

Research Collection Lee Kong Chian School Of Business

The current research explored whether perspective-taking increases willingness to engage in contact with stereotyped outgroup members. Across three studies, we find that perspective-taking increases willingness to engage in contact with negatively-stereotyped targets. In Study 1, perspective-takers sat closer to, whereas stereotype suppressors sat further from, a hooligan compared to control participants. In Study 2, individual differences in perspective-taking tendencies predicted individuals’ willingness to engage in contact with a hooligan, having effects above and beyond those of empathic concern. Finally, Study 3 demonstrated that perspective-taking’s effects on intergroup contact extend to the target’s group (i.e., another homeless man), but not to …

Ratings Lead You To The Product, Reviews Help You Clinch It? The Dynamics And Impact Of Online Review Sentiments On Products Sales, Nan Hu, Noi Sian Koh, Srinivas K. Reddy

Research Collection Lee Kong Chian School Of Business

It is generally assumed that ratings are a numeric representation of text sentiments and their valences are consistent. This however may not always be true. Using a panel of data on over 4000 books from Amazon.com, we develop a multiple equation model to examine the inter-relationships between ratings, sentiments, and sales. We find that ratings do not have a significant direct impact on sales but have an indirect impact through sentiments. Sentiments, however, have a direct significant impact on sales. Our findings also indicate that the two most accessible types of reviews - most helpful and most recent - play …

Anticipated Regret In Time-Based Work-Family Conflict, Jessica Bagger, Jochen Reb, Andrew Li

Research Collection Lee Kong Chian School Of Business

The primary purpose of this research was to investigate the role of anticipated regret in time-based work-family conflict decisions.

A total of 90 working parents responded to a decision making problem describing a time-based conflict between a work event and a family event. Participants' preference for which event to attend constituted the dependent variable. Independent variables were participants' work and family centralities. Anticipated regret for choosing the work option and anticipated regret for choosing the family option were measured as hypothesized mediators.

Structural equation modeling revealed that anticipated regret for choosing the family option mediated the relationship between work centrality …

Refocusing The Lens: Singapore's Private Enterprises In China, Caroline Yeoh, Wilfred Pow Ngee How, Ye Zhang

Research Collection Lee Kong Chian School Of Business

In recent years, financial and political instabilities have cooled economic growth in many regions. Even in this context, however, areas of strong growth remain; none, arguably, more prominent than ever-developing and increasingly affluent China, which is today a vastly different environment than even several years ago. More than ever, a wealth of opportunity subsists in this ancient land – and businesses must be able to adapt and seize these opportunities. Thus we turn towards Singapore private enterprise in China, to study once more the efficacy of the city-state's internationalization strategies in the context of the private enterprises which must eventually …

Sox, Corporate Transparency, And The Cost Of Debt, Sandro Andrade, Gennaro Bernile, Frederick Hood

Research Collection Lee Kong Chian School Of Business

We investigate the impact of the Sarbanes–Oxley (SOX) Act on the cost of debt through its effect on the reliability of financial reporting. Using Credit Default Swap (CDS) spreads and a structural CDS pricing model, we calibrate a firm-level corporate opacity parameter in the pre- and post-SOX periods. Our analysis shows that corporate opacity and the cost of debt decrease significantly after SOX. The median firm in our sample experiences an 18 bp reduction on its five-year CDS spread as a result of lower opacity following SOX, amounting to total annual savings of $ 844 million for the 252 firms …

Tracking-Error Models For Multiple Benchmarks: Theory And Empirical Performance, Yunchao Xu, Zhichao Zheng, Karthik Natarajan, Chung-Piaw Teo

Research Collection Lee Kong Chian School Of Business

We propose a new multiple-benchmark tracking-error model for portfolio selection problem. The tracking error of a portfolio from a set of benchmark portfolios is defined as the difference between its return and the highest return from the set of benchmarks. We derive closedform solution of our portfolio strategy, whose main component is the sum of the benchmark portfolios weighted by their respective probabilities of attaining the highest return among the portfolios in the benchmark. These probabilities, also known as the persistency values, are less sensitive to estimation errors in the means and covariances. These features help to stabilize the computational …

Transforming Business School Futures: Business Model Innovation And The Continued Search For Academic Legitimacy, Howard Thomas, Eric Cornuel

Research Collection Lee Kong Chian School Of Business

The business school is certainly one of the major success stories in higher education over the last 40 years. Despite this success there have been many more recent comments and criticisms and about the purpose, role and academic stature of business schools. Thomas et al. (2013, pp. 8-9) outline thoroughly the nature of these criticisms in the following manner: “Critics accuse business schools of doing arcane, irrelevant and impractical academic research; doing a poor job of preparing students for management careers; pandering to the market and the media rankings; failing to ask important questions; and in the process of responding …

Financial Reporting Opacity And Expected Crash Risk: Evidence From Implied Volatility Smirks, Jeong-Bon Kim, Liandong Zhang

Research Collection School Of Accountancy

The recent financial crisis has stimulated a renewed interest in understanding the determinants of stock price crash risk (i.e., left tail risk). Recent research shows that opaque financial reports enable managers to hide and accumulate bad news for extended periods. When the accumulated bad news reaches certain tipping point, it will be suddenly released to the market at once, resulting in an abrupt decline in stock price (i.e., a crash). This study extends this line of research by examining the impact of financial reporting opacity on perceived or expected crash risk. Prominent economists, such as Olivier Blanchard, argue that removing …

Beauty And Academic Career, Hai Lu, Yanju Liu, Kevin Veenstra

Research Collection School Of Accountancy

We examine the impact of beauty on the academic career success of tenure-track accounting professors at top business schools in America, and show that beauty plays a significant role. Specifically, after controlling for gender, ethnicity, publication history, work experience, and quality of alma mater, more attractive professors obtain better first school placements post-PhD and are granted tenure in a shorter period of time. Interestingly, there is no incremental benefit of attractiveness for the career progression from associate to full professor. These findings are consistent with our conjecture that when the signal of an individual’s potential is noisy, beauty becomes a …

Stock Liquidity And The Pricing Of Earnings: A Comparison Of China’S Floating And Non-Floating Shares, Jiwei Wang, Kevin Chen, Hongqi Yuan

Research Collection School Of Accountancy

The reform to convert non-floating shares to floating in China provides a setting in which shares are subject to different liquidity constraint. We show that the severity of this constraint is inversely related to the extent to which earnings information is reflected in the share prices. Specifically, before the reform, the transfer prices of non-floating shares reflect much less earnings information than the market prices of floating shares. After the reform, however, both types of transfer reflect more earnings information, although the weights are still less than that found in the market prices. Thus, China's unique setting shows that share …

Governing A Digital Business Ecosystem: Lessons From One.Motoring Portal, Gary Pan, See Liang Foo, Shongye Tan

Research Collection School Of Accountancy

While the IT innovation topic has gathered significant research interests, the existing discourse on IT innovation is centered on internal organizational processes such as IT capability development and organizational learning rather than IT innovation networks as the primary means for achieving superior enterprise performance. This is an important topic because a networked perspective of IT-enabled innovation is a critical dimension for the dynamics of collaborative innovation in today’s networked economy. In particular, the development and implementation of a digital business ecosystem (DBE); a specific type of business ecosystem defined as an IT-enabled business network of entities with differing interests bound …
