Limited Attention, Marital Events And Hedge Funds, Yan Lu, Sugata Ray, Melvyn Teo Dec 2016

Limited Attention, Marital Events And Hedge Funds, Yan Lu, Sugata Ray, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

We explore the impact of limited attention by analyzing the performance of hedge fund managers who are distracted by marital events. We find that marriages and divorces are associated with significantly lower fund alpha, during the six-month period surrounding and the two-year period after the event. Busy managers who manage multiple funds and who are not part of a team are more affected by marital transitions. Inattentive managers place fewer active bets relative to their style peers, load more on index stocks, exhibit higher R-squareds with respect to systematic factors, and are more prone to the disposition effect.

Entry Of Copycats Of Luxury Brands, Sarah Yini Gao, Wei Shi Lim, Christopher S. Tang Dec 2016

Entry Of Copycats Of Luxury Brands, Sarah Yini Gao, Wei Shi Lim, Christopher S. Tang

Research Collection Lee Kong Chian School Of Business

We develop a game-theoretic model to examine the entry of copycats and its implications by incorporating two salient features; these features are two product attributes, i.e., physical resemblance and product quality, and two consumer utilities, i.e., consumption utility and status utility. Our equilibrium analysis suggests that copycats with a high physical resemblance but low product quality are more likely to successfully enter the market by defying the deterrence of the incumbent. Furthermore, we show that higher quality can prevent the copycat from successfully entering the market. Finally, we show that the entry of copycats does not always improve consumer surplus …

Appointment Systems Under Service Level Constraints, David Chen, Rowan Wang, Zhenzhen Yan, Saif Benjaafar, Oualid Jouini Dec 2016

Appointment Systems Under Service Level Constraints, David Chen, Rowan Wang, Zhenzhen Yan, Saif Benjaafar, Oualid Jouini

Research Collection Lee Kong Chian School Of Business

We consider a new model of appointment scheduling where customers are given the earliest possible appointment times under the service level constraint that the expected waiting time of each individual customer cannot exceed a given threshold. We apply the theory of majorization to analytically characterize the structure of the optimal appointment schedule. We show that, the optimal inter-appointment times increase with the order of arrivals. That is, the optimal inter-arrival time between two customers later in the arrival process is longer than that between two customers earlier in the arrival process. We study the limiting behavior of our system, and …

The Effect Of Monetary Policy On Bank Wholesale Funding, Hyunsoo Choi, Hyun Soo Choi Dec 2016

The Effect Of Monetary Policy On Bank Wholesale Funding, Hyunsoo Choi, Hyun Soo Choi

Research Collection Lee Kong Chian School Of Business

We study how monetary policy affects the funding composition of the banking sector. When monetary tightening reduces the retail deposit supply due to, for example, a decrease in bank reserves or in money demand, banks try to substitute the deposit outflows with more wholesale funding in order to mitigate the policy impact on their lending. Banks have varying degrees of accessibility to wholesale funding sources because of financial frictions, and those banks that are large or that have a greater reliance on wholesale funding increase their wholesale funding more. As a result, monetary tightening increases both the reliance on and …

Public Hedge Funds, Lin Sun, Melvyn Teo Dec 2016

Public Hedge Funds, Lin Sun, Melvyn Teo

Research Collection Lee Kong Chian School Of Business

Hedge funds managed by listed firms significantly underperform funds managed by unlisted firms. The underperformance is more severe for funds with low manager deltas, poor governance, and no manager co-investment, or managed by firms whose prices are sensitive to earnings news. Notwithstanding the underperformance, listed firms raise more capital and harvest greater fee revenues than do comparable unlisted firms. The results cannot be explained by endogeneity, backfill bias, serial correlation, or manager manipulation, and are consistent with the view that, for asset management firms, going public weakens the alignment between ownership, control, and investment capital, thereby engendering conflicts of interest.

Socially Responsible Firms, Allen Ferrell, Hao Liang, Luc Renneboog Dec 2016

Socially Responsible Firms, Allen Ferrell, Hao Liang, Luc Renneboog

Research Collection Lee Kong Chian School Of Business

In the corporate finance tradition, starting with Berle and Means (1932), corporations should generally be run to maximize shareholder value. The agency view of corporate social responsibility (CSR) considers CSR an agency problem and a waste of corporate resources. Given our identification strategy by means of an instrumental variable approach, we find that well-governed firms that suffer less from agency concerns (less cash abundance, positive pay-for-performance, small control wedge, strong minority protection) engage more in CSR. We also find that a positive relation exists between CSR and value and that CSR attenuates the negative relation between managerial entrenchment and value.

Increase In Takeover Protection And Firm Knowledge Accumulation Strategy, Heli Wang, Shan Zhao, Jinyu He Dec 2016

Increase In Takeover Protection And Firm Knowledge Accumulation Strategy, Heli Wang, Shan Zhao, Jinyu He

Research Collection Lee Kong Chian School Of Business

Research summary: We argue that the extent to which a firm faces takeover threats affects its knowledge structure. In particular, takeover threats may lead to managers' reluctance to adopt a strategy toward firm-specific knowledge accumulation because implementing this strategy requires them to acquire specialized skills, which are at risk under takeover threats. Conversely, takeover protection leads to an increase in firm-specific knowledge. Further, the relationship between takeover protection and firm-specific knowledge is positively moderated by managerial ownership, which helps align managerial interests with those of shareholders. But the relationship is negatively moderated by managerial tenure, as long-tenured managers have already …

Simulations For Crisis Communication: The Use Of Social Media, Siyoung Chung Dec 2016

Simulations For Crisis Communication: The Use Of Social Media, Siyoung Chung

Research Collection Lee Kong Chian School Of Business

Simulations have been widely used in crisis and emergency communication for practitioners but have not reached classrooms in higher education. The purpose of this study was to investigate the effects that simulations using social media have on learning of crisis communication among college students. To explore the effects, a real-time crisis simulation activity using social media are created for 132 undergraduate students enrolled at a business school. Both quantitative and qualitative data collected from pre- and post-simulation surveys are used to investigate the benefits of simulations on learning and identify the challenges the participants experienced.

Short Selling Meets Hedge Fund 13f: An Anatomy Of Informed Demand, Yawen Jiao, Massimo Massa, Hong Zhang Dec 2016

Short Selling Meets Hedge Fund 13f: An Anatomy Of Informed Demand, Yawen Jiao, Massimo Massa, Hong Zhang

Research Collection Lee Kong Chian School Of Business

The existing literature treats the short side (i.e., short selling) and the long side of hedge fund trading (i.e., fund holdings) independently. The two sides, however, complement each other: opposite changes in the two are likely to be driven by information, whereas simultaneous increases (decreases) of the two may be motivated by hedging (unwinding) considerations. We use this intuition to identify informed demand and document that it exhibits highly significant predictive power over returns (approximately 10% per year). We also find that informed demand forecasts future firm fundamentals, suggesting that hedge funds play an important role in information discovery. (C) …

Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong Yang, Cayirli Tugba, Mei Wan Low Dec 2016

Predicting The Performance Of Queues: A Data Analytic Approach, Kum Khiong Yang, Cayirli Tugba, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Existing models of multi-server queues with system transience and non-standard assumptions are either too complex or restricted in their assumptions to be used broadly in practice. This paper proposes using data analytics, combining computer simulation to generate the data and an advanced non-linear regression technique called the Alternating Conditional Expectation (ACE) to construct a set of easy-to-use equations to predict the performance of queues with a scheduled start and end time. Our results show that the equations can accurately predict the queue performance as a function of the number of servers, mean arrival load, session length and service time variability. …

Management Research In Amj: Celebrating Impact While Striving For More, Gerard George Dec 2016

Management Research In Amj: Celebrating Impact While Striving For More, Gerard George

Research Collection Lee Kong Chian School Of Business

Over the years, I have read articles or listened to panel discussions that question the value of management scholarship, and often critiqued its relevance or insightfulness for an applied profession. On occasion, I have sided with those who are more pessimistic of our future as a field. While there are many truths in these commentaries, they might not give adequate credit to the robust knowledge production ecosystem that generates applied insight with scientific rigor. Yes, there is a lot more we can do but we should also celebrate the work we do well. Having read over 4000 manuscripts as an …

Understanding And Tackling Societal Grand Challenges Through Management Research, Gerard George, Jennifer Howard-Grenville, Aparna Joshi, Laszlo Tihanyi Dec 2016

Understanding And Tackling Societal Grand Challenges Through Management Research, Gerard George, Jennifer Howard-Grenville, Aparna Joshi, Laszlo Tihanyi

Research Collection Lee Kong Chian School Of Business

“Grand challenges” are formulations of global problems that can be plausibly addressed through coordinated and collaborative effort. In this Special Research Forum, we showcase management research that examines societal problems that individuals, organizations, communities, and nations face around the world. We develop a framework to guide future research to provide systematic empirical evidence on the formulation, articulation, and implementation of grand challenges. We highlight several factors that likely enhance or suppress the attainment of collective goals, and identify representative research questions for future empirical work. In so doing, we aspire to encourage management scholars to engage in tackling broader societal …

Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia Kong, Chung-Yee Lee, Chung-Piaw Teo, Zhichao Zheng Dec 2016

Appointment Sequencing: Why The Smallest-Variance-First Rule May Not Be Optimal, Qingxia Kong, Chung-Yee Lee, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

We study the design of a healthcare appointment system with a single physician and a group of patients whose service durations are stochastic. The challenge is to find the optimal arrival sequence for a group of mixed patients such that the expected total cost of patient waiting time and physician overtime is minimized. While numerous simulation studies report that sequencing patients by increasing order of variance of service duration (Smallest-Variance-First or SVF rule) performs extremely well in many environments, analytical results on optimal sequencing are known only for two patients. In this paper, we shed light on why it is …

Knowledge Will Set You Free: Financial Awareness And Inclusion In The Bottom Of The Pyramid, Aurobindo Ghosh Nov 2016

Knowledge Will Set You Free: Financial Awareness And Inclusion In The Bottom Of The Pyramid, Aurobindo Ghosh

Research Collection Lee Kong Chian School Of Business

In this project, we explored whether financial literacy and economic awareness alleviates financial exclusion for the general population, particularly the financially underserved sections of the population in Ho Chi Minh City (HCMC) in Vietnam. We overcame the problem of identifying the financially excluded by looking at multiple measures of financial inclusion including frequency of bank use, access to borrowing for business, having a regular savings plan and having some insurance for possible future unfavorable outcomes. Using an innovative principal component (PCA) based method we identified a single score factor that can be construed as an overall measure of the degree …

Can Asians Be Creative?, Chua, Roy Y. J., Jerry Zremski

Research Collection Lee Kong Chian School Of Business

A crotchety American named Henry Ford invented a modern, fast and efficient way to manufacture automobiles and a Japanese man named Eiji Toyoda refined and perfected it. A series of innovators across the western world developed the television - and the tech specialists at Sony, Toshiba and a host of other Asian companies found ways to make TVs better, cheaper, faster. And an idiosyncratic Californian named Steve Jobs invented a company that made a smart phone for the masses - and then outsourced the manufacturing to China. If you detect a pattern here, you are not alone. Asia may be …

Valuation Uncertainty, Market Sentiment And The Informativeness Of Institutional Trades, Lisa Yang, Jeremy Goh, Chiraphol N. Chiyachantana Nov 2016

Valuation Uncertainty, Market Sentiment And The Informativeness Of Institutional Trades, Lisa Yang, Jeremy Goh, Chiraphol N. Chiyachantana

Research Collection Lee Kong Chian School Of Business

Prior studies indicate that institutional investors are informed, in the sense that their trades predict price changes. In this study we show that return predictive ability of institutions arises (after controlling for size, book-to-market, and momentum) mainly from institutional sales of hard-to-value stocks during periods of positive market sentiment. These results support the notion that these stocks tend to be overvalued during periods of bullish market sentiment, and institutions contribute to market efficiency by identifying and trading on these overpriced stocks.

State Ownership And Corporate Innovation Efficiency, Jerry X. Cao, Douglas J. Cumming, Sili Zhou, Lu Zhou Nov 2016

State Ownership And Corporate Innovation Efficiency, Jerry X. Cao, Douglas J. Cumming, Sili Zhou, Lu Zhou

Research Collection Lee Kong Chian School Of Business

The conventional wisdom is that state ownership may hinder patenting through reduced incentives and pronounced agency problems associated with state-owned enterprises (SOEs). Empirical evidence from a variety of contexts, including the U.S., Europe, and China, is consistent with this view, including evidence that shows that reductions in state ownership are associated with an increase in patent counts. In this paper, we investigate the innovative efficiency of Chinese SOEs. Innovative efficiency refers to patents/R&D expenditure, and not patent counts. The data indicate that SOEs, and especially central government SOEs, are substantially more innovatively efficient than non-SOEs. The relative innovative efficiency of …

Least Squares Approximation To The Distribution Of Project Completion Times With Gaussian Uncertainty, Zhichao Zheng, Karthik Natarajan, Chung-Piaw Teo Nov 2016

Least Squares Approximation To The Distribution Of Project Completion Times With Gaussian Uncertainty, Zhichao Zheng, Karthik Natarajan, Chung-Piaw Teo

Research Collection Lee Kong Chian School Of Business

This paper is motivated by the following question: How to construct good approximation for the distribution of the solution value to linear optimization problem when the random objective coefficients follow a multivariate normal distribution? Using Stein’s Identity, we show that the least squares normal approximation of the random optimal value can be computed by estimating the persistency values of the corresponding optimization problem. We further extend our method to construct a least squares quadratic estimator to improve the accuracy of the approximation; in particular, to capture the skewness of the objective. Computational studies show that the new approach provides more …

Days To Cover And Stock Returns, Harrison G. Hong, Frank Weikai Li, Sophie X. Ni, Jose A. Scheinkman, Philip Yan Nov 2016

Days To Cover And Stock Returns, Harrison G. Hong, Frank Weikai Li, Sophie X. Ni, Jose A. Scheinkman, Philip Yan

Research Collection Lee Kong Chian School Of Business

A crowded trade emerges when speculators' positions are large relative to the asset's liquidity, making exit difficult. We study this problem of recent regulatory concern by focusing on short-selling. We show that days to cover (DTC), the ratio of short interest to trading volume, measures the costliness of exiting crowded trades. Crowding is an important concern as short-sellers avoid illiquid stocks, which we establish using an instrumental-variables strategy involving staggered stock market decimalization reforms. Arbitrageurs require a premium to enter into such trades as a strategy shorting high DTC stocks and buying low DTC stocks generates a 1.2% monthly return. …

Blame The Shepherd Not The Sheep: Imitating Higher-Ranking Transgressors Mitigates Punishment For Unethical Behavior, Christopher W. Bauman, Leigh Plunkett Tost, Ong, Madeline Nov 2016

Blame The Shepherd Not The Sheep: Imitating Higher-Ranking Transgressors Mitigates Punishment For Unethical Behavior, Christopher W. Bauman, Leigh Plunkett Tost, Ong, Madeline

Research Collection Lee Kong Chian School Of Business

Do bad role models exonerate others’ unethical behavior? Based on social learning theory and psychologicaltheories of blame, we predicted that unethical behavior by higher-ranking individuals changes howpeople respond to lower-ranking individuals who subsequently commit the same transgression. Fivestudies explored when and why this rank-dependent imitation effect occurs. Across all five studies, wefound that people were less punitive when low-ranking transgressors imitated high-ranking membersof their organization. However, imitation only reduced punishment when the two transgressors werefrom the same organization (Study 2), when the transgressions were highly similar (Study 3), and whenit was unclear whether the initial transgressor was punished (Study 5). …

Bargaining Zone Distortion In Negotiations: The Elusive Power Of Multiple Alternatives, Michael Schaerer, David D. Loschelder, Roderick I. Swaab Nov 2016

Bargaining Zone Distortion In Negotiations: The Elusive Power Of Multiple Alternatives, Michael Schaerer, David D. Loschelder, Roderick I. Swaab

Research Collection Lee Kong Chian School Of Business

We challenge the assumption that having multiple alternatives is always better than a single alternative by showing that negotiators who have additional alternatives ironically exhibit downward-biased perceptions of their own and their opponent’s reservation price, make lower demands, and achieve worse outcomes in distributive negotiations. Five studies demonstrate that the apparent benefits of multiple alternatives are elusive because multiple alternatives led to less ambitious first offers (Studies 1–2) and less profitable agreements (Study 3). This distributive disadvantage emerged because negotiators’ perception of the bargaining zone was more distorted when they had additional (less attractive) alternatives than when they only had …

Interpersonal Dynamics In Assessment Center Exercises: Effects Of Role Player Portrayed Disposition, Tom Oliver, Peter Hausdorf, Filip Lievens, Peter Conlon Nov 2016

Interpersonal Dynamics In Assessment Center Exercises: Effects Of Role Player Portrayed Disposition, Tom Oliver, Peter Hausdorf, Filip Lievens, Peter Conlon

Research Collection Lee Kong Chian School Of Business

Although interpersonal interactions are the mainstay of many assessment center exercises, little is known about how these interactions unfold and affect participant behavior and performance. More specifically, participants interact with role players who have been instructed to demonstrate behavior reflecting specific dispositions as part of the exercise. This study focuses on role player portrayed disposition as a potentially important social demand relevant to participant behavior and performance in interpersonal simulations. We integrate interpersonal theory and trait activation theory to formulate hypotheses about the effects of role player portrayed disposition on participant behavior and performance in 184 interpersonal simulations. A significant …

Decimalization, Ipo Aftermath, And Liquidity, Charlie Charoenwong, David K. Ding, Tiong Yang Thong Nov 2016

Decimalization, Ipo Aftermath, And Liquidity, Charlie Charoenwong, David K. Ding, Tiong Yang Thong

Research Collection Lee Kong Chian School Of Business

We investigate the effect of decimalization on the aftermarket trading of NYSE-listed IPOs. We find that the relation between bid–ask spread and underpricing becomes negative post-decimalization, suggesting that benefits from the increased price competition accrue more to hot IPOs. The quoted depth is generally smaller post-decimalization due to a higher probability of front running, which aggravates the cost of adverse selection and limit order submission. We show that underwriters continue to provide price support but are only willing to cover the initial short position, if profitable to do so. Decimal pricing does not affect the flipping strategy of institutions for …

Informal Institutions And The Geography Of Innovation: An Integrative Perspective, Xuesong Geng, Kenneth G. Huang Nov 2016

Informal Institutions And The Geography Of Innovation: An Integrative Perspective, Xuesong Geng, Kenneth G. Huang

Research Collection Lee Kong Chian School Of Business

Integrating the insights from both institutional theory and economic geography, we develop a new conceptual framework to explain how formal and informal institutions in developing countries influence knowledge exchanges within and across geographical locations, thus affecting entrepreneurs’ and firms’ innovative behaviors and outputs. We suggest that the prevalence of informal institutions in developing countries increases the importance of geographic proximity for knowledge exchanges. At the same time, informal institutions provide alternative channels for maintaining non-local social interactions that facilitate knowledge exchanges among geographically distant firms. Using China as the context, we provide theoretical propositions that illustrate these mechanisms in terms …

Sociability, Golf Courses, And The Performance Of Institutional Investors, Chi Shen Wei, Lei Zhang Oct 2016

Sociability, Golf Courses, And The Performance Of Institutional Investors, Chi Shen Wei, Lei Zhang

Research Collection Lee Kong Chian School Of Business

We hypothesize that prestigious golf courses attract golfers and visitors from across the country, providing greater opportunities for nearby investors to build social connections. Our evidence suggests that institutional investors located near prestigious golf courses earn significantly better benchmark- and risk-adjusted returns. This reflects the benefits of sociability as our findings are stronger for golf courses with reciprocal guest policies that allow wider participation and increase when major golf championships rotate to the state. Their portfolios reveal hallmarks of active trading – higher concentration, greater selectivity, more frequent turnover – and include more distant stocks. To establish a causal link, …

The recent advent of remote sensing, mobile technologies, novel transaction systems, and high performance computing offers opportunities to understand trends, behaviors, and actions in a manner that has not been previously possible. Researchers can thus leverage 'big data' that are generated from a plurality of sources including mobile transactions, wearable technologies, social media, ambient networks, and business transactions. An earlier AMJ editorial explored the potential implications for data science in management research and highlighted questions for management scholarship, and the attendant challenges of data sharing and privacy (George, Haas & Pentland, 2014). This nascent field is evolving rapidly and at …

When Do You Procrastinate? Sleep Quality And Social Lag Jointly Predict Self-Regulatory Failure At Work, Jana Kuhnel, Ronald Bledow, Nicolas Feuerhahn Oct 2016

When Do You Procrastinate? Sleep Quality And Social Lag Jointly Predict Self-Regulatory Failure At Work, Jana Kuhnel, Ronald Bledow, Nicolas Feuerhahn

Research Collection Lee Kong Chian School Of Business

This study investigates antecedents of procrastination, the tendency to delay the initiation or completion of work activities. We examine this phenomenon from a self-regulation perspective and argue that depleted self-regulatory resources are an important pathway to explain why and when employees procrastinate. The restoration of self-regulatory resources during episodes of non-work is a prerequisite for the ability to initiate action at work. As sleep offers the opportunity to replenish self-regulatory resources, employees should procrastinate more after nights with low-quality sleep and shorter sleep duration. We further propose that people's social sleep lag amplifies this relationship. Social sleep lag arises if …
