How To Make Online Auctions More Successful – For Both Sellers And Buyers, Knowledge@Smu
Knowledge@SMU
With the growing popularity of the Internet and digital communication, the efficiency of the online auction has attracted increasing attention. In an article titled, “The Value of Reputation: Evidence from Online Auctions,” four scholars at Beijing University - Zhou Lian, Zhang Weiying, Gu Quanlin and Shen Yi – use data provided by Eachnet, a Chinese online auction company with the biggest market share in China before being acquired by eBay in 2003, to analyze the various factors that contribute to a successful online auction.

Will Google And Baidu's Arrival Reshape The Mobile Search Industry In China?, Knowledge@Smu
Knowledge@SMU
China Mobile, China’s largest cell phone carrier, and Google, the world’s largest search engine, announced in January a “mobile search” partnership in China. Nine days later, China Unicom, China’s second-largest cell-phone carrier, reportedly entered into talks with Baidu, the Chinese search engine, about developing a similar alliance in China. The news marked the spread of search-engine warfare from computers to cell phones. For both Baidu and Google, a partnership with mobile operators is expected to help them win a significant number of subscribers in a short period of time. Will Google and Baidu’s arrival reshape the mobile search industry in …
Valuing Information Technology Infrastructures: A Growth Options Approach, Qizhi Dai, Robert J. Kauffman, Salvatore T. March
Valuing Information Technology Infrastructures: A Growth Options Approach, Qizhi Dai, Robert J. Kauffman, Salvatore T. March
Research Collection School Of Computing and Information Systems
Decisions to invest in information technology (IT) infrastructure are often made based on an assessment of its immediate value to the organization. However, an important source of value comes from the fact that such technologies have the potential to be leveraged in the development of future applications. From a real options perspective, IT infrastructure investments create growth options that can be exercised if and when an organization decides to develop systems to provide new or enhanced IT capabilities. We present an analytical model based on real options that shows the process by which this potential is converted into business value, …
Employer Branding In The Belgian Army: The Importance Of Instrumental And Symbolic Beliefs For Potential Applicants, Actual Applicants, And Military Employees, Filip Lievens
Research Collection Lee Kong Chian School Of Business
This study conceptualizes employer brand as a package of instrumental and symbolic attributes. Using a sample of 955 individuals (429 potential applicants, 392 actual applicants, and 134 military employees), we examine the relative importance of instrumental and symbolic employer brand beliefs across different groups of individuals: potential applicants, actual applicants, and military employees (with less than three years of tenure). Results show that instrumental attributes explain greater variance in the Army's attractiveness as an employer among actual applicants compared to potential applicants or employees. In all three groups, symbolic trait inferences explain a similar portion of the variance. In addition, …
Realized Daily Variance Of S&P500 Cash Index: A Revaluation Of Stylized Facts, Shirley J. Huang, Qianqiu Liu, Jun Yu
Realized Daily Variance Of S&P500 Cash Index: A Revaluation Of Stylized Facts, Shirley J. Huang, Qianqiu Liu, Jun Yu
Research Collection Lee Kong Chian School Of Business
In this paper, the realized daily variance is obtained from intraday transaction prices of the S&P 500 cash index over the period from January 1993 to December 2004. When constructing realized daily variance, market microstructure noise is taken into account using a technique proposed by Zhang, Mykland, and Ait-Sahalia (2005). The time series properties of realized daily variance are compared with those of variance estimates obtained from parametric GARCH and stochastic volatility models. Unconditional and dynamic properties concerning the realized daily variance are examined, the relationship between realized variance and returns is investigated, and the stylized facts concerning realized daily …
Organizational Identity And Employer Image: Towards A Unifying Framework, Filip Lievens, Greet Van Hoye, Frederik Anseel
Organizational Identity And Employer Image: Towards A Unifying Framework, Filip Lievens, Greet Van Hoye, Frederik Anseel
Research Collection Lee Kong Chian School Of Business
This study aims to bridge two research streams that have evolved relatively apart from each other, namely the research streams on organizational identity and on employer branding (employer image). In particular, we posit that it is crucial to examine which factors company outsiders (applicants) as well as company insiders (employees) associate with a given employer. To this end, this study uses the instrumental-symbolic framework to study factors relating to both employer image and organizational identity of the Belgian Army. Two samples are used: a sample of 258 Army applicants and a sample of 179 military employees. Results show that both …
Public Disclosure And Private Decisions: The Case Of Equity Market Execution Quality, Ekkehart Boehmer, Robert Jennings, Li Wei
Public Disclosure And Private Decisions: The Case Of Equity Market Execution Quality, Ekkehart Boehmer, Robert Jennings, Li Wei
Research Collection Lee Kong Chian School Of Business
In 2001, the Securities and Exchange Commission (SEC) required market centers to publish monthly execution-quality reports in an effort to spur competition for order flow between markets. Using samples of stocks trading on several markets, we investigate whether past execution quality affects order-routing decisions and whether the new disclosure requirements influence this relationship. We find that routing decisions are associated with execution quality; markets reporting low execution costs and fast fills subsequently receive more orders. Moreover, the reports themselves appear to provide information that was unavailable previously. Our results are consistent with active competition for order flow that can be …
Evaluating Dynamic Performance: The Influence Of Salient Gestalt Characteristics On Performance Ratings, Jochen Reb, Russell Cropanzano
Evaluating Dynamic Performance: The Influence Of Salient Gestalt Characteristics On Performance Ratings, Jochen Reb, Russell Cropanzano
Research Collection Lee Kong Chian School Of Business
It is well recognized that performance changes over time. However, the effect of these changes on overall assessments of performance is largely unknown. In a laboratory experiment, we examined the influence of salient Gestalt characteristics of a dynamic performance profile on supervisory ratings. We manipulated performance trend (flat, linear-improving, linear-deteriorating, U-shaped, and ∩-shaped), performance variation (small, large), and performance mean (negative, zero, positive) within subjects and display format (graphic, tabular) between subjects. Participants received and evaluated information about the weekly performance of different employees over a simulated 26-week period. Results showed strong main effects on performance ratings of both performance …
A Comparison Of Cross Training Policies In Different Job Shops, Kum Khiong Yang
A Comparison Of Cross Training Policies In Different Job Shops, Kum Khiong Yang
Research Collection Lee Kong Chian School Of Business
This research compares a set of cross-training policies represented by different numbers of cross-trained workers, additional skills per cross-trained worker, and additional machines. The policies are evaluated in job shops, represented by different efficiency losses, labour utilization, variability in processing times, and worker absenteeism. Our results show that adding one machine in each department and cross-training one or two workers from each department with one additional skill is generally sufficient to realize most of the benefits of cross-training. Cross-training is thus beneficial in most job shops, unless the cost of the minimal training and spare machines is high. Our results …

A Cautionary Note On The Effects Of Range Restriction On Predictor Intercorrelations, Paul R. Sackett, Filip Lievens, Christopher M. Berry, Richard N. Landers
A Cautionary Note On The Effects Of Range Restriction On Predictor Intercorrelations, Paul R. Sackett, Filip Lievens, Christopher M. Berry, Richard N. Landers
Research Collection Lee Kong Chian School Of Business
The purpose of this research report is to highlight a unique set of issues that arise when considering the effects of range restriction in the context of estimating predictor intercorrelations. Three approaches are used to illustrate the issue: simulation, a concrete applied example, and a reanalysis of a meta-analysis of ability-interview correlations. The general conclusion is that a predictor intercorrelation can differ dramatically from the population value when both predictors are used in a composite that is used operationally for selection. The compensatory nature of a composite means that low scorers on one predictor can only obtain high scores on …

Research Collection Lee Kong Chian School Of Business
Management consultants are a significant social and economic force. Few people, whether as citizens or members oforganizations, will have escaped the impact of their interventions. A survey revealed that 97 percent of the top 200 companies in the U.K. and U.S. have used management consultants. The spectacular growth of the industry in the last fiftyyears is evidenced by the fact that somewhere in the regionof 80 percent of firms currently operating were establishedafter 1980. The ratio of consultants to managers, as this bookdemonstrates, has grown from one to a hundred in 1965 toone to thirteen in 1995. In this clearly …
An Examination Of Strategies For Encouraging Feedback Interest After Career Assessment, Frederik Anseel, Filip Lievens
An Examination Of Strategies For Encouraging Feedback Interest After Career Assessment, Frederik Anseel, Filip Lievens
Research Collection Lee Kong Chian School Of Business
This study examines how feedback interest after career assessment can be influenced by changing individuals' beliefs about the importance and modifiability of the various performance dimensions. In an experiment, 82 master students completed a computerized assessment tool developed for assessing managerial potential. Results showed that participants in the experimental condition were more interested in feedback about important dimensions as opposed to unimportant dimensions and were more interested in feedback about nonmodifiable dimensions as opposed to modifiable dimensions. These findings might assist career counselors and organizations in designing strategies that direct feedback interest toward performance dimensions that are most important for …
Investing In Hedge Funds When Returns Are Predictable, Doron Avramov, Robert Kosowski, Narayan Y. Naik, Melvyn Teo
Investing In Hedge Funds When Returns Are Predictable, Doron Avramov, Robert Kosowski, Narayan Y. Naik, Melvyn Teo
Research Collection BNP Paribas Hedge Fund Centre
This paper evaluates hedge fund performance through portfolio strategies that incorporate predictability in managerial skills, fund risk loadings, and benchmark returns. Incorporating predictability substantially improves performance for the entire universe of hedge funds as well as for various investment styles. The outperformance is strongest during market downturns when the marginal utility of consumption is relatively high. Moreover, the major source of investment profitability is predictability in managerial skills. In particular, long-only strategies that incorporate predictability in managerial skills outperform their Fung and Hsieh (2004) benchmarks by over 17 percent per year. The economic value of predictability obtains for different rebalancing …
Foreign Funds Spy Hidden Bounties In Indian Distressed Assets, Knowledge@Smu
Foreign Funds Spy Hidden Bounties In Indian Distressed Assets, Knowledge@Smu
Knowledge@SMU
Foreign funds are garnering a sizable presence in India's nascent market for distressed assets, which is currently estimated between $45 billion and $55 billion. India's economic boom offers pockets of opportunity for investors to buy underperforming assets such as cement and sugar plants, revive them with fresh capital or liquidate them to profit handsomely. A big driver for this growing market is the government's move to purge the financial system of sick assets accumulated over decades, but obstacles include the absence of a developed corporate debt market, limits on foreign investments and procedural bottlenecks. India Knowledge@Wharton spoke to key participants …

Mike Mccue's Vision For The Convergence Of The Phone And The Web, Knowledge@Smu
Knowledge@SMU
When Mike McCue founded Tellme in 1999, its initial product was a voice-driven information service, what might be termed a "voice portal." Today, the company's voice-recognition systems power directory assistance services from AT&T, Verizon and Cingular along with automated 800-number customer help lines at companies like Merrill Lynch and Federal Express. But McCue still harbors dreams of a broader voice-driven web, one which will provide consumers with new ways of using the phone to interact with the universe of information. He discussed this vision, and others, during a recent interview with Knowledge@Wharton in Tellme's Mountain View, Calif., offices.

Sustaining Corporate Growth Requires 'Big I' And 'Small I' Innovation, Knowledge@Smu
Knowledge@SMU
All companies, from major multinationals to start-ups, face a common challenge: how to keep growing. These firms find it difficult to sustain growth because they become risk averse, opting for safer incremental product and service improvements instead of more rewarding, but riskier, major initiatives, according to a study by Wharton marketing professor George S. Day. Companies, Day says, need to better understand the risks inherent in different levels of innovation and achieve a balance between BIG I innovation and small i innovation.

Hampered by poor infrastructure, bureaucratic red tape and restrictive labor laws, Indian manufacturing has failed to make its presence felt globally. But that is rapidly changing, say experts from Boston Consulting Group and Wharton. More and more multinationals are setting up manufacturing operations in India, attracted by India's burgeoning domestic market and its relatively low-cost, highly skilled workforce.

Microsoft's Vista operating system should give the company a revenue stream that will run for years, but experts at Wharton say the January 30 launch of the consumer versions of Microsoft's flagship software may be among the last of its kind -- a product sold for a flat fee in a shrink-wrapped box. Indeed, many wonder if the software business model that has made Microsoft so dominant may begin to fade as new software business models -- from open source to advertising supported -- gain increasing traction.

It sounds like something from a futuristic TV thriller: American spies thwarting a terrorist plot through a shared online community modeled after Wikipedia, the free user-created, web-based encyclopedia. But Anthony D. Williams, co-author of the new book, Wikinomics: How Mass Collaboration Changes Everything, recently told a conference at Wharton's Mack Center for Technological Innovation that this online community of spies already exists -- along with a host of other activist-oriented web sites that are changing the rules of the global economy.

Why Hedge Funds Are Looking To India For Greater Upside Potential, Knowledge@Smu
Knowledge@SMU
A few years ago, hedge funds were barely on the radar screen in the Indian marketplace, and they were highly secretive investment vehicles even in the U.S. Today, it's a different story. As big returns are no longer easy to come by in domestic markets, international hedge funds are increasingly looking to countries like India and evaluating investment opportunities and the potential gains to be made. To understand what factors affect their success, India Knowledge@Wharton talked to experts from Wharton and elsewhere about the attractiveness -- as well as the risks -- of the Indian marketplace for hedge funds.

Logistics Network Design With Supplier Consolidation Hubs And Multiple Shipment Options, Michelle L. F. Cheong, Rohit Bhatnagar, Stephen C. Graves
Research Collection School Of Computing and Information Systems
An important service provided by third-party logistics (3PL) firms is to manage the inbound logistics of raw materials and components from multiple suppliers to several manufacturing plants. A key challenge for these 3PL firms is to determine how to coordinate and consolidate the transportation flow, so as to get the best overall logistics performance. One tactic is to establish consolidation hubs that collect shipments from several suppliers, consolidate these shipments, and direct the consolidated shipments to the appropriate manufacturing plant. We consider the network design problem to implement this tactic, namely deciding the number, location and operation of consolidation hubs …

Business Output And Business Experience: Evidence From China's Nongovernmental Businesses, Liangjun Su
Research Collection School Of Economics
We study the application of the Solow growth model in China's non-governmental businesses and propose a reasonable modification for it. Our analysis indicates that business experience is closely tied to the output of China's non-governmental businesses. Our major findings include: (1) the business experience has little overall impact on the elasticity of output with respect to labour; (2) the business experience has a large impact on the elasticity of output with respect to capital and the elasticity increases as the business experience increases; (3) the adjusted Solow residual that reflects technological progress exhibits a negative relationship with the business experience, …

On Stiffness In Affine Asset Pricing Models, Shirley Junying Huang, Jun Yu
Research Collection Lee Kong Chian School Of Business
Economic and econometric analysis of continuous-time affine asset pricing models often necessitates solving systems of ordinary differential equations (ODEs) numerically. Explicit RungeûKutta (ERK) methods have been suggested to solve these ODEs both in the theoretical finance literature and in the financial econometrics literature. In this paper we show that under many empirically relevant circumstances the ODEs involve stiffness, a phenomenon which leads to some practical difficulties for numerical methods with a finite region of absolute stability, including the whole class of ERK methods. The difficulties are highlighted in the present paper in the context of pricing zero-coupon bonds as well …

A Cardan’S Discriminant Approach To Predicting Currency Crashes, Benedict Seng Kee Koh, Wai Mun Fong, Fabrice Chan
Research Collection Lee Kong Chian School Of Business
This paper models large swings in exchange rates by introducing nonlinearity via the generalized normal (GEN) distribution [Lye, J.N., Martin, V.L., 1993. Robust estimation, nonnormalities and generalized exponential distributions. Journal of the American Statistical Association 88, 261-267]. As the distribution allows for bimodality, a switch between modes may give rise to currency crashes. A statistic known as Cardan's discriminant, based on the shape parameters of the GEN, is used to detect bimodality. The Cardan's discriminant is found to reliably predict currency crashes for eight emerging countries and generate relatively low false signals for stable currencies.
Why Global Banks Are Banking On India, Knowledge@Smu
Why Global Banks Are Banking On India, Knowledge@Smu
Knowledge@SMU
Foreign banks are aggressively expanding in India, both organically and through acquisitions. After playing along the sidelines in the country for more than 100 years, they have galvanized themselves to secure their share -- and more -- of the new action in the rapidly growing economy and a boom in high-profit consumer lending. India's central bank has outlined the roadmap for foreign players to grow, while the banking industry's robust fundamentals and crisis-free track record are other draws. To be sure, the entrenched public sector banks don't relish the charge of foreign banks. But the real rivals on the competing …

With the development of a market economy in China, private companies have attracted more attention from academic researchers. For example, scholars Wang Xuanyu, Li Xingchun and Chen Ling analyzed Guangdong Huadi Group, a well-known Chinese manufacturer of household appliances based in Guangdong, a province in south China, in order to identify those factors that contribute to the success of a non-family business. The results of their study are in a paper titled, “Capital Joint-Venture and Trust Expansion--Research on non-family Entrepreneurial Partnership”.

The 'Myth Of Market Share': Can Focusing Too Much On The Competition Harm Profitability?, Knowledge@Smu
Knowledge@SMU
Business has long been likened to warfare, according to Wharton marketing professor Scott Armstrong, so it is hardly surprising that companies strive to beat their competitors and wrest away as much market share as possible. But such efforts not only waste time and energy, they can actually be detrimental to the firm's profitability, according to Armstrong. Based on new research and examples from today's business environment, Armstrong and co-author Kesten Green suggest that overemphasis on market share is the wrong approach. --------------------------------------------------------------------------------

For Microsoft, 2006 was a year of new product introductions: the Windows Vista operating system, a new version of Office and the Zune music player, to name a few. For Microsoft CEO Steve Ballmer -- who spoke at Wharton recently as part of the school's Leadership Lecture series -- these new products serve as a reminder of his goals: Convince customers that Microsoft's latest products are ground-breaking, transform a company with $44 billion in sales into an agile innovator, compete against new business models and recruit enough talent to keep the software giant relevant 25 years from now.
