Speculating On Home Improvements, Hyun Soo Choi, Harrison Hong, Jose Scheinkman Mar 2014

Speculating On Home Improvements, Hyun Soo Choi, Harrison Hong, Jose Scheinkman

Research Collection Lee Kong Chian School Of Business

We develop a speculation-based theory of home improvements. Housing services are produced from a mix of land and structures. Homeowners have an option to increase their structures (i.e. make improvements) holding fixed their land. Speculative improvements arise because overconfident homeowners mistakenly believe they can add to structures for a lower cost than a competitive construction industry. Improvements are increasing and convex in home prices. There is excessive home remodeling in equilibrium. And the change in the recoup ratio (the ratio of resale value of improvements to construction costs) is negatively correlated with construction cost growth controlling for home price appreciation. …

Forecasting The Equity Risk Premium: The Role Of Technical Indicators, Christopher J. Neely, David E. Rapach, Jun Tu, Guofu Zhou Mar 2014

Forecasting The Equity Risk Premium: The Role Of Technical Indicators, Christopher J. Neely, David E. Rapach, Jun Tu, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

Academic research relies extensively on macroeconomic variables to forecast the U.S. equity risk premium, with relatively little attention paid to the technical indicators widely employed by practitioners. Our paper fills this gap by comparing the predictive ability of technical indicators with that of macroeconomic variables. Technical indicators display statistically and economically significant in-sample and out-of-sample predictive power, matching or exceeding that of macroeconomic variables. Furthermore, technical indicators and macroeconomic variables provide complementary information over the business cycle: technical indicators better detect the typical decline in the equity risk premium near business-cycle peaks, whereas macroeconomic variables more readily pick up the …

Distributionally Robust Mixed Integer Linear Programs: Persistency Models With Applications, Xiaobo Li, Karthik Natarajan, Chung-Piaw Teo, Zhichao Zheng Mar 2014

Distributionally Robust Mixed Integer Linear Programs: Persistency Models With Applications, Xiaobo Li, Karthik Natarajan, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

In this paper, we review recent advances in the distributional analysis of mixed integer linear programs with random objective coefficients. Suppose that the probability distribution of the objective coefficients is incompletely specified and characterized through partial moment information. Conic programming methods have been recently used to find distributionally robust bounds for the expected optimal value of mixed integer linear programs over the set of all distributions with the given moment information. These methods also provide additional information on the probability that a binary variable attains a value of 1 in the optimal solution for 0–1 integer linear programs. This probability …

Examining The Growth Of Digital Wireless Phone Technology: A Take-Off Theory Analysis, Angsana A. Techatassanasoontorn, Robert J. Kauffman Feb 2014

Examining The Growth Of Digital Wireless Phone Technology: A Take-Off Theory Analysis, Angsana A. Techatassanasoontorn, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

The early phase of diffusion plays a critical role in determining information technology (IT) success in a market. Takeoff, the transition point from the introduction to the growth phase in the IT life cycle, is viewed as an acid test for whether a technology will succeed. We develop a theory to understand global takeoff for digital wireless phones that can be extended to other technologies with related characteristics. Drawing on technology dominance and product life cycle theories, we build a model that consists of standards, market competition, technology costs, and technology substitution to explain takeoff and subsequent market penetration growth. …

Managerial Agency Costs Of Socialistic Internal Capital Markets: Empirical Evidence From China, Jiwei Wang, Kangtao Ye Feb 2014

Managerial Agency Costs Of Socialistic Internal Capital Markets: Empirical Evidence From China, Jiwei Wang, Kangtao Ye

Research Collection School Of Accountancy

This study provides empirical evidence of managerial agency costs in socialistic internal capital markets. Listed Chinese companies are required to disclose the amount of resources that are reallocated to other firms of the parent company, which provides us with a direct measure of the socialistic subsidization of weak member firms by strong member firms within a business group. We hypothesize that in strong member firms, managerial compensation is less sensitive to firm performance because cross-subsidization makes it difficult for group CEOs to hold the managers in strong firms accountable for their own firms' performance, and also increases the noise in …

Pricing Strategy For Cloud Computing Services, Jianhui Huang Feb 2014

Pricing Strategy For Cloud Computing Services, Jianhui Huang

Dissertations and Theses Collection (Open Access)

The cloud computing services market exhibits unique characteristics such as instant accessibility, fluctuating demand and supply, and interruptible service provision. Various pricing mechanisms exist in current industry practice. None of these pricing mechanisms, however, is comprehensive enough to capture all these features in a way that allows the vendors to optimize resource allocation. This dissertation identifies key factors related to cloud computing pricing, and examines their interplays. This research uses multiple approaches, including a market survey, game theory modeling, simulation, lab experiments and econometric modeling, to analyze the pricing strategy of cloud services vendors. A field study of a representative …

The Price Discovery Puzzle In Offshore Yuan Trading: Different Contributions For Different Contracts, David K. Ding, Yiuman Tse, Michael R. Williams Feb 2014

The Price Discovery Puzzle In Offshore Yuan Trading: Different Contributions For Different Contracts, David K. Ding, Yiuman Tse, Michael R. Williams

Research Collection Lee Kong Chian School Of Business

The People's Bank of China (PBC) lifted yuan trading restrictions in July of 2010 that led to offshore yuan spot trading in Hong Kong. Based on causality analyses, we find that price discovery is absent between the onshore and offshore spot markets. However, we document the presence of price discovery between onshore spot and offshore nondeliverable forward (NDF) rates. These seemingly inconsistent results present a puzzle wherein one offshore market appears to be more informationally integrated with the onshore market than another. We conclude that price discovery differences in the offshore markets stem from the offshore spot and forward contracts …

The Power Of The Weak, Martin Gargiulo, Gokhan Ertug Feb 2014

The Power Of The Weak, Martin Gargiulo, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

Weak organizational actors can overcome the consequences of their dependence by securing the control of valuable resources or by embedding dependence relationships into social networks. While these strategies may not eliminate the underlying dependence, they can curtail the ability or the willingness of the stronger party to use power. Embedding strategies, however, can also have unintended consequences. Because the network structures that confer power to the weak are inherently more stable, they can persist beyond the point of being beneficial, trapping weak actors into unsuitable network structures. The power of the weak can thus become the weakness of the strong.

Personality And Group Performance: The Importance Of Personality Composition And Work Tasks, Amit Kramer, Devasheesh P. Bhave, Tiffany D. Johnson Feb 2014

Personality And Group Performance: The Importance Of Personality Composition And Work Tasks, Amit Kramer, Devasheesh P. Bhave, Tiffany D. Johnson

Research Collection Lee Kong Chian School Of Business

We examine whether group members’ Big Five personality composition (variability, minimum, and maximum) affects the group’s performance. We employed an experimental design where participants were paid based on their performance in two different group-based experimental tasks: an additive task (where group performance is based on the sum of efforts of all group members) and a conjunctive task (where group performance is based on the performance of the weakest group member). Results indicate that variability in extraversion is positively related to group performance on the additive task but not on the conjunctive task. Conversely, neuroticism maximum score is negatively related to …

Emotional Intelligence Predicts Success In Medical School, Nele Libbrecht, Filip Lievens, Bernd Carette, Stephane Cote Feb 2014

Emotional Intelligence Predicts Success In Medical School, Nele Libbrecht, Filip Lievens, Bernd Carette, Stephane Cote

Research Collection Lee Kong Chian School Of Business

Accumulating evidence suggests that effective communication and interpersonal sensitivity during interactions between doctors and patients impact therapeutic outcomes. There is an important need to identify predictors of these behaviors, because traditional tests used in medical admissions offer limited predictions of "bedside manners" in medical practice. This study examined whether emotional intelligence would predict the performance of 367 medical students in medical school courses on communication and interpersonal sensitivity. One of the dimensions of emotional intelligence, the ability to regulate emotions, predicted performance in courses on communication and interpersonal sensitivity over the next 3 years of medical school, over and above …

Exploring The Locus Of Invention: The Dynamics Of Network Communities And Firms' Invention Productivity, Maxim Sytch, Adam Tatarynowicz Feb 2014

Exploring The Locus Of Invention: The Dynamics Of Network Communities And Firms' Invention Productivity, Maxim Sytch, Adam Tatarynowicz

Research Collection Lee Kong Chian School Of Business

Departing from prior research analyzing the implications of social structure for actors' outcomes by applying either an ego network or a global network perspective, this study examines the implications of network communities for the invention productivity of firms. Network communities represent dense and nonoverlapping structural groups of actors in a social system. A network community lens helps identify new ways to study firms' access to diverse knowledge inputs in a dynamic system of interorganizational relationships. Specifically, we examine how the membership dynamics of a network community affect the invention productivity of member firms by either enabling or constraining access to …

Systematic Reflection: Implications For Learning From Failures And Successes, Shmuel Ellis, Bernd Carette, Frederik Anseel, Filip Lievens Feb 2014

Systematic Reflection: Implications For Learning From Failures And Successes, Shmuel Ellis, Bernd Carette, Frederik Anseel, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Drawing on a growing stream of empirical findings that runs across different psychological domains, we demonstrated that systematic reflection stands out as a prominent tool for learning from experience. For decades, failed experiences have been considered the most powerful learning sources. Despite the theoretical and practical relevance, few researchers have investigated whether people can also learn from their successes. We showed that through systematic reflection, people can learn from both their successes and their failures. Studies have further shown that the effectiveness of systematic reflection depends on situational (e.g., reflection focus) and person-based (e.g., conscientiousness) factors. Given today's unrelenting pace …

New Bounds For The Price Of Anarchy Under Nonlinear And Asymmetric Cost, Deren Han, Jie Sun, Marcus Ang Feb 2014

New Bounds For The Price Of Anarchy Under Nonlinear And Asymmetric Cost, Deren Han, Jie Sun, Marcus Ang

Research Collection Lee Kong Chian School Of Business

We derive new bounds for the price of anarchy under nonlinear and asymmetric costs. The bounds depend on an additional factor called the intrinsic cost of the system and therefore tend to be more accurate than the current bounds that are dependent only on the degree of asymmetry of the Jacobian and the degree of the nonlinearity of the cost function.

Rethinking Management Scholarship: From The Editors, Gerard George Feb 2014

Rethinking Management Scholarship: From The Editors, Gerard George

Research Collection Lee Kong Chian School Of Business

Rethinking management scholarship is perhaps a tad bit bold as an opening statement for the 20th editorial team of the Academy of Management Journal, but it does capture the spirit and aspiration of the incoming team. It is not that this team intends to recast decades of cumulative knowledge, but instead the goal is to experiment on what we as an Academy collectively consider as good empirical research and the way in which we examine or present management scholarship. Our proposal is not quite as drastic as it might sound; perhaps what is new is how we plan to articulate …

Leading Mindfully: Two Studies Of The Influence Of Supervisor Trait Mindfulness On Employee Well-Being And Performance, Jochen Reb, Jayanth Narayanan, Sankalp Chaturvedi Feb 2014

Leading Mindfully: Two Studies Of The Influence Of Supervisor Trait Mindfulness On Employee Well-Being And Performance, Jochen Reb, Jayanth Narayanan, Sankalp Chaturvedi

Research Collection Lee Kong Chian School Of Business

This research examines the influence of leaders’ mindfulness on employee well-being and performance. We hypothesized that supervisors’ trait mindfulness is positively associated with different facets of employee well-being, such as job satisfaction and need satisfaction, and different dimensions of employee performance, such as in-role performance and organizational citizenship behaviors. We also explored whether one measure of employee well-being, psychological need satisfaction, plays a mediating role in the relation between supervisor mindfulness and employee performance. We tested these predictions in two studies using data from both supervisors and their subordinates. Results were consistent with our hypotheses. Overall, this research contributes to …

Reading Between The Lines: Financial Reporting, Implied Corporate Social Responsibility And Corporate Financial Performance, C. Ferreira, David K. Ding, U. Wongchoti

Research Collection Lee Kong Chian School Of Business

We provide one of the first analyses of corporate social responsibility (CSR) and firm performance using only annual financial reports. We document a link between corporate financial performance (CFP) and CSR, although this is not always positive. Specifically, we investigate whether CSR performance can be implied from financial reporting and provide evidence that CSR information implied by financial reports have a significant association with CFP. Furthermore, we provide the first comprehensive study of CSR reporting and link it with CFP in New Zealand.

Comparison As Incentive: Newsvendor Decisions In A Social Context, Buket Avci, Zeina Loutfi, Jurgen Mihm, Elena Belavina, Steffen Keck

Research Collection Lee Kong Chian School Of Business

Explicit formal mechanisms dominate the discussion about incentives in Operations Management, yet many other mechanisms exist. Social comparison between peers may provide strong implicit incentives for individuals. Social comparison arises naturally in all social settings and may thus be unintended; however, many companies deliberately use it to motivate employees. In this study, we model a social context in which purchasers evaluate their performance relative to their peers; a feeling of inferiority results in a negative contribution to utility, whereas a feeling of superiority results in a positive contribution. We find that social comparison induces characteristic deviations from the newsvendor optimum …

The Limits Of The Market-Wide Limits Of Arbitrage: Insights From The Dynamics Of 100 Anomalies, Hieiko Jacobs Jan 2014

The Limits Of The Market-Wide Limits Of Arbitrage: Insights From The Dynamics Of 100 Anomalies, Hieiko Jacobs

Research Collection BNP Paribas Hedge Fund Centre

Are anomalies strongest when limits of arbitrage are widely considered to be greatest? We empirically explore this theoretically deducted prediction. We first identify, categorize, and replicate 100 anomalies in the cross-section of expected equity returns. We then comprehensively study their dynamic interaction with popular proxies for time-varying market-level arbitrage conditions. Our findings reveal a surprisingly weak role of commonly employed measures of market-wide arbitrage risks and constraints. Even though this “big picture” evidence is by no means conclusive, our findings might potentially be best interpreted as supporting the growing literature which uncovers some shortcomings of the limits to arbitrage argument.

Click fraud - the deliberate clicking on advertisements with no real interest on the product or service offered - is one of the most daunting problems in online advertising. Building an elective fraud detection method is thus pivotal for online advertising businesses. We organized a Fraud Detection in Mobile Advertising (FDMA) 2012 Competition, opening the opportunity for participants to work on real-world fraud data from BuzzCity Pte. Ltd., a global mobile advertising company based in Singapore. In particular, the task is to identify fraudulent publishers who generate illegitimate clicks, and distinguish them from normal publishers. The competition was held from …
