Research Collection Lee Kong Chian School Of Business

With the rapid advancement of digital finance in China, accessing wealth management services through digital platforms has become considerably convenient. However, the potential impact of digital platform investments on residents' consumption remains a relatively unexplored question. This study addresses this gap by leveraging a unique dataset obtained from one of China's largest fintech companies, encompassing individual-level data on consumption and investment. Our findings indicate that engaging in digital platform investments can indeed stimulate residents' consumption. Importantly, participation in digital platform investment has an inclusive effect, with a more pronounced marginal impact on consumption among low-income residents and in-dividuals residing in …


Commentary: Black Or White? Wrong Or Right? Don't Rush To Take Sides On Complex Issues Such As Israel-Hamas Conflict, Siow-Heng Ong, Benjamin Joshua Ong Oct 2023

In Customer Service, When Is A Full Refund Justified?, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Associate Professor of Marketing Hannah Chang discussed the challenges in achieving balance between making genuine amends for the specific incident and strategic reputation management when customers complain. She also noted the challenges in balancing between offering genuine redress and not setting precedents that encourage unreasonable demands. Assoc Prof Chang also shared how companies can take preventive measures by setting clear policies for refunds or compensation, and monitoring online sentiment to stay ahead of brewing issues, thus allowing businesses to address concerns in real time.


Interpersonal Behavior In Assessment Center Role-Play Exercises: Investigating Structure, Consistency, And Effectiveness, Simon M. Breil, Filip Lievens, Boris Forthmann, Mitla D. Back Sep 2023

Interpersonal Behavior In Assessment Center Role-Play Exercises: Investigating Structure, Consistency, And Effectiveness, Simon M. Breil, Filip Lievens, Boris Forthmann, Mitla D. Back

Research Collection Lee Kong Chian School Of Business

Although the behaviors displayed by assessees are the currency of assessment centers (ACs), they have remained largely unexplored. This is surprising because a better understanding of assessees' behaviors may provide the missing link between research on the determinants of assessee performance and research on the validity of performance ratings. Therefore, this study draws on behavioral personality science to scrutinize the behaviors that assessees express in interpersonal AC exercises. Our goals were to investigate (a) the structure of interpersonal behaviors, (b) the consistency of these behaviors across AC exercises, and (c) their effectiveness. We obtained videotaped performances of 203 assessees who …


Does Abstract Thinking Facilitate Information Processing? Evidence From Financial Analysts, Frank Weikai Li, Rong Wang, Yang Yu, Gloria Yang Yu Sep 2023

Does Abstract Thinking Facilitate Information Processing? Evidence From Financial Analysts, Frank Weikai Li, Rong Wang, Yang Yu, Gloria Yang Yu

Research Collection Lee Kong Chian School Of Business

We study whether abstract thinking – an essential cognitive trait established by psychological and neuroscientific studies – facilitates analysts’ information processing. Exploiting analysts’ questions during earnings calls, we construct an Abstract Thinking Index (ATI) that measures their tendency to involve abstract words, logical reasoning, broader topics, and future outlooks. We find that abstract thinking improves analysts’ forecast accuracy and recommendation informativeness. Consistent with abstract thinking featuring identifying central characteristics and comprehending intangible things, ATI has stronger effects for firms with fundamentals co-moving more with peers and less tangible information. Additional analyses suggest that ATI captures analysts’ cognitive traits rather than …


What Drives The Value Of Financial Analysts’ Advice? The Role Of Earnings And Growth Forecasts, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach Sep 2023

What Drives The Value Of Financial Analysts’ Advice? The Role Of Earnings And Growth Forecasts, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach

Research Collection Lee Kong Chian School Of Business

We offer a parsimonious index at the individual analyst level to measure the extent to which an analyst relies on earnings and long-term growth forecasts in producing her advice. Using this index, we evaluate the contribution of earnings and growth forecasts to the investment value of analysts’ stock recommendations. We find that the fraction of analysts’ advice attributed to forecasts varies considerably across analysts and sectors. The investment value of recommendations is higher for analysts who rely less on their forecasts and more on other sources of information when forming investment advice. Investors recognize the superiority of recommendations from analysts …


Geographic Distance And State's Grip: Information Asymmetry, State Inattention, And Firm Implementation Of State Policy, Xiyi Yang, Heli Wang, Xiaoyu Zhou Sep 2023

Geographic Distance And State's Grip: Information Asymmetry, State Inattention, And Firm Implementation Of State Policy, Xiyi Yang, Heli Wang, Xiaoyu Zhou

Research Collection Lee Kong Chian School Of Business

In this study, we develop the argument that geographic distance between the state and local governments undermines the state's capacity to influence the implementation of state policies by local organizations. Drawing from information economics and the attention-based view, we propose that physical distance reduces the state's monitoring effectiveness through two interrelated mechanisms: information asymmetry and state leaders' inattention to distant issues. Using data of Chinese public firms' implementation of environmental activities between 2008 and 2016, we find that firms conduct fewer environmental activities required by the state when they are regulated by local governments that are more geographically distant to …


Constrained By Localized Attention Focus: The Negative Effect Of Firm-Specific Knowledge On Exploratory Firm Innovation, Bilian Ni Sullivan, Kaixian Mao, Heli Wang Sep 2023

Constrained By Localized Attention Focus: The Negative Effect Of Firm-Specific Knowledge On Exploratory Firm Innovation, Bilian Ni Sullivan, Kaixian Mao, Heli Wang

Research Collection Lee Kong Chian School Of Business

Integrating the resource-based view (RBV) and attention-based view (ABV), this study explores the impact of firm-specific knowledge (FSK) on a firm's exploratory innovation and the role of government support in this process. We argue that firms with a high degree of specificity in their knowledge assets tend to have a more localized attention focus, leading to those firms with less exposure to distant and diverse information and knowledge. Consequently, such firms are likely to have reduced exploratory innovative outputs. However, government resource support could expand a firm's attention focus beyond local searches, mitigating its negative effects. Based on a unique …


Public Sentiments And The Influence Of Information-Seeking Preferences On Knowledge, Attitudes, Death Conversation And Receptiveness Towards Palliative Care: Results From A Nationwide Survey In Singapore, Su Lin Yeo, Raymond Han Lip Ng, Tan Ying Peh, May O. Lwin, Poh Heng Chong, Patricia Soek Hui Neo, Jamie Xuelian Zhou, Angel Lee Sep 2023

Public Sentiments And The Influence Of Information-Seeking Preferences On Knowledge, Attitudes, Death Conversation And Receptiveness Towards Palliative Care: Results From A Nationwide Survey In Singapore, Su Lin Yeo, Raymond Han Lip Ng, Tan Ying Peh, May O. Lwin, Poh Heng Chong, Patricia Soek Hui Neo, Jamie Xuelian Zhou, Angel Lee

Research Collection Lee Kong Chian School Of Business

Background: Low awareness about palliative care among the global public and healthcare communities has been frequently cited as a persistent barrier to palliative care acceptance. Given that knowledge shapes attitudes and encourages receptiveness, it is critical to examine factors that influence the motivation to increase knowledge. Health information-seeking from individuals and media has been identified as a key factor, as the process of accessing and interpreting information to enhance knowledge has been shown to positively impact health behaviours. Objective: Our study aimed to uncover public sentiments toward palliative care in Singapore. A conceptual framework was additionally developed to investigate the …

In a commentary, SMU Associate Professor of Strategy & Entrepreneurship (Education) Kenneth Goh discussed and debunked three groundless myths that get in the way of workforce inclusivity. He also called for companies to seek expert advice from relevant agencies and explore partnerships with institutions of higher learning, such as SMU, to pursue inclusivity in a sustainable manner. He added that SMU provides its students opportunities to work with companies and examine the feasibility of their inclusivity initiatives as part of their coursework.


Overcoming Procrastination: Time Pressure And Positive Affect As Compensatory Routes To Action, Jana Kuhnel, Ronald Bledow, Angela Kuonath Aug 2023

Overcoming Procrastination: Time Pressure And Positive Affect As Compensatory Routes To Action, Jana Kuhnel, Ronald Bledow, Angela Kuonath

Research Collection Lee Kong Chian School Of Business

The current work seeks to identify factors that support action initiation from the theoretical lens of self-regulation. Specifically, we focus on factors that reduce procrastination, the delay of the initiation or completion of activities. We draw from action control theory and propose that positive affect operates as a personal and time pressure as a situational factor that unblock routes to action. High positive affect makes people less prone to procrastination because positive affect reduces behavioral inhibition and facilitates the enactment of intentions. By contrast, when positive affect is low, people depend on time pressure as an action facilitating stimulus. We …


Gender Bias In Cultural Tightness Across The 50 U.S. States And Its Links To Gender Inequality In Leadership And Innovation, Xin Qin, Roy Y. J. Chua, Ling Tan, Wanlu Li, Chen Chen Aug 2023

Gender Bias In Cultural Tightness Across The 50 U.S. States And Its Links To Gender Inequality In Leadership And Innovation, Xin Qin, Roy Y. J. Chua, Ling Tan, Wanlu Li, Chen Chen

Research Collection Lee Kong Chian School Of Business

Cultural tightness theory, which holds that “tight” cultures have rigid norms and sanctions, provides unique insights into cultural variations. However, current theorizing has not analyzed gender differences in cultural tightness. Addressing this gap, this research shows that women are more constrained than men by norms within the same society. By recruiting 15,425 respondents, we mapped state-level gender bias in cultural tightness across the United States. Variability in gender bias in cultural tightness was associated with state-level socio-political factors (religion and political ideology) and gender-related threats. Gender bias in cultural tightness was positively associated with state-level gender inequality in (business and …


Effects Of A Mindfulness-Based Leadership Training On Leadership Behaviors And Effectiveness, Nina Tan, Eva Katharina Peters, Jochen Reb Aug 2023

Effects Of A Mindfulness-Based Leadership Training On Leadership Behaviors And Effectiveness, Nina Tan, Eva Katharina Peters, Jochen Reb

Research Collection Lee Kong Chian School Of Business

Objectives: Organizations increasingly integrate mindfulness elements into their leadership development. However, there is limited evidence supporting the efficacy of mindfulness-based leadership training (MBLT) due to a scarcity of intervention studies. Theoretically, little is known about mediating mechanisms through which MBLT might affect leadership effectiveness. Thus, this research examined whether MBLT can improve leadership effectiveness and whether leadership behaviors mediated this effect.MethodsWe conducted a quasi-experimental study conducted in a real-world setting with an active control condition. Sixty leaders from various industries participated in either a 2-day intensive MBLT workshop followed by three individual coaching sessions over 3 months, or a presentation …

Why Employees Accept Lower Pay At Mission-Oriented Companies, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer Jul 2023

Why Employees Accept Lower Pay At Mission-Oriented Companies, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer

Research Collection Lee Kong Chian School Of Business

Today’s companies are likely to tout how their work benefits human welfare or “makes the world a better place.” Recent research suggests that this may come with a potential financial drawback for workers, as it can inhibit them from negotiating for higher pay. Over five studies, job candidates consistently reported that they worried asking for higher pay from these companies would be seen as greedy or inappropriate. This suggests they are aware of a common bias, known as motivation purity bias, where managers believe employees interested in material rewards of work (such as pay) are less motivated than those motivated …


Workplace Culture Must Emphasise Mutual Respect [In Chinese], Siow-Heng Ong Jul 2023

Workplace Culture Must Emphasise Mutual Respect [In Chinese], Siow-Heng Ong

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Professor of Communication Management (Education) Ong Siow Heng discussed the importance of having a respectful culture in the workplace. He opined that one way to appreciate employees is to provide equitable pay and career advancement opportunities for staff, so that workers will know that their employer respects their contribution. Even though more forms of disrespect for workers are being addressed by law, Prof Ong opined that improving respect for the workers’ dignity is best managed by those in workplace leadership even before relevant laws are passed, especially in areas that cannot be covered by law. He …


Seeking Better Sharpe Ratio Via Bayesian Optimization, Peng Liu Jul 2023

Seeking Better Sharpe Ratio Via Bayesian Optimization, Peng Liu

Research Collection Lee Kong Chian School Of Business

Developing an excellent quantitative trading strategy to obtain a high Sharpe ratio requires optimizing several parameters at the same time. Example parameters include the window length of a moving average sequence, the choice of trading instruments, and the thresholds used to generate trading signals. Simultaneously optimizing all these parameters to seek a high Sharpe ratio is a daunting and time-consuming task, partly because of the unknown mechanism determining the Sharpe ratio. This article proposes using Bayesian optimization to systematically search for the optimal parameter configuration that leads to a high Sharpe ratio. The author shows that the proposed intelligent search …


Growing Up Under Mao And Deng: On The Ideological Determinants Of Corporate Policies, Hao Liang, Rong Wang, Haikun Zhu Jun 2023

Growing Up Under Mao And Deng: On The Ideological Determinants Of Corporate Policies, Hao Liang, Rong Wang, Haikun Zhu

Research Collection Lee Kong Chian School Of Business

Historically, economic activities have been organized around certain ideologies. We investigate the impact of politicians’ ideology on corporate policies by exploring a unique setting of ideological change—China from Mao to Deng around the 1978 economic reform—in a regression discontinuity framework. We find that the age discontinuity of politicians around 18 years old in 1978, who had already joined the Chinese Communist Party (CCP) or joined soon thereafter and later became municipal paramount leaders, has had a lasting effect on contemporary firm- and city-level policies. In particular, firms in cities with mayors that joined the CCP under the ideological regime of …


How Transformational Leadership Transforms Followers’ Affect And Work Engagement, Benjamin Bader, Michael Gielnik, Ronald Bledow Jun 2023

How Transformational Leadership Transforms Followers’ Affect And Work Engagement, Benjamin Bader, Michael Gielnik, Ronald Bledow

Research Collection Lee Kong Chian School Of Business

How do episodes of transformational leadership transform followers? To address this question, we build on theories of affective events and affect regulation and develop a research model that explicates a mechanism of the transformation process implicit in transformational leadership theory. Specifically, the model explains how experiencing episodes of transformational leadership transforms (i.e., changes) followers’ positive affect and eventually their work engagement by fulfilling followers’ basic psychological needs. We tested our model in two independent longitudinal samples using daily and weekly measurement designs with 214 (N = 75) and 147 (N = 54) lagged observations, respectively. In support of our model, …


Singapore Management University (Smu): Tracking The Strategy Evolution Of A Start-Up University, Michelle P. Lee, Howard Thomas, Alex Wilson Jun 2023

Singapore Management University (Smu): Tracking The Strategy Evolution Of A Start-Up University, Michelle P. Lee, Howard Thomas, Alex Wilson

Research Collection Lee Kong Chian School Of Business

The year 2020 marked the 20th anniversary of the Singapore Management University (SMU). SMU exists in an ecosystem for higher education that is quite unlike what one might find in other parts of the world. The supportive and stable environment the Singapore government provided in terms of its funding and policies meant a more predictable environment within which a university can make long-range planning. Singapore's development since its independence in 1965 has been undergirded by the belief that a strong educational system is the backbone of the country's economic development. The Era of Evolution is a story of both implementation …


Mindfully Outraged: Mindfulness Increases Deontic Retribution For Third-Party Injustice, Adam A. Kay, Theodore Charles Masters-Waage, Jochen Reb, Pavlos A. Vlachos Jun 2023

Mindfully Outraged: Mindfulness Increases Deontic Retribution For Third-Party Injustice, Adam A. Kay, Theodore Charles Masters-Waage, Jochen Reb, Pavlos A. Vlachos

Research Collection Lee Kong Chian School Of Business

Mindfulness is known to temper negative reactions by both victims and perpetrators of injustice. Accordingly, critics claim that mindfulness numbs people to injustice, raising concerns about its moral implications. Exam-ining how mindful observers respond to third-party injustice, we integrate mindfulness with deontic justice theory to propose that mindfulness does not numb but rather enlivens people to injustice committed by others against others. Results from three studies show that mindfulness heightens moral outrage in witnesses of injustice, particularly when the injustice is only moderate. Although these findings did not replicate with a mindfulness induction, post-hoc analysis in a fourth study reveals …


Asset-Rich And Cash-Poor: Which Older Adults Value Reverse Mortgages?, Joelle H. Fong, Olivia S. Mitchell, Benedict S. K. Koh May 2023

Asset-Rich And Cash-Poor: Which Older Adults Value Reverse Mortgages?, Joelle H. Fong, Olivia S. Mitchell, Benedict S. K. Koh

Research Collection Lee Kong Chian School Of Business

Home equity represents a substantial share of retirement wealth for many older persons, particularly in Asia where national housing policies have encouraged home-ownership. This paper explored the potential for reverse mortgages to help 'asset-rich and cash-poor' older Singaporeans unlock their home equity while ageing in place. The empirical analysis was based on a nationally representative survey of home-owners age 50+ in the 2018 Singapore Life Panel (N = 6,258). Our analyses showed that the average older home-owner holds some 60 per cent of total net wealth in housing equity, suggestive of high demand potential for reverse mortgage products. Nevertheless, actual …


The Mutual Constitution Of Culture And Psyche: The Bidirectional Relationship Between Individuals’ Perceived Control And Cultural Tightness-Looseness, Anyi Ma, Krishna Savani, Fangzhou Liu, Kenneth Tai, Aaron C. Kay May 2023

The Mutual Constitution Of Culture And Psyche: The Bidirectional Relationship Between Individuals’ Perceived Control And Cultural Tightness-Looseness, Anyi Ma, Krishna Savani, Fangzhou Liu, Kenneth Tai, Aaron C. Kay

Research Collection Lee Kong Chian School Of Business

According to the theory of mutual constitution of culture and psyche, just as culture shapes people, individuals’ psychological states can influence culture. We build on compensatory control theory, which suggests that low personal control can lead people to prefer societal systems that impose order, to examine the mutual constitution of personal control and cultural tightness. Specifically, we tested whether individuals’ lack of personal control increases their preference for tighter cultures as a means of restoring order and predictability, and whether tighter cultures in turn reduce people’s feelings of personal control. Seven studies (five preregistered) with participants from the United States, …


Pay Suppression In Social Impact Contexts: How Framing Work Around The Greater Good Inhibits Job Candidate Compensation Demands, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer May 2023

Pay Suppression In Social Impact Contexts: How Framing Work Around The Greater Good Inhibits Job Candidate Compensation Demands, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer

Research Collection Lee Kong Chian School Of Business

Past research suggests that when organizations communicate the benefits of their work for human welfare—that is, use a social impact framing for work—job candidates are willing to accept lower wages because they expect the work to be personally meaningful. We argue that this explanation overlooks a less socially desirable mechanism by which social impact framing leads to lower compensation demands: the perception among job candidates that requesting higher pay will breach organizational expectations to value work for its intrinsic (rather than extrinsic) rewards, or constitute a motivational norm violation. We find evidence for our theory across five studies: a qualitative …


Arousing Motives Or Eliciting Stories? On The Role Of Pictures In A Picture–Story Exercise, Philipp Schäpers, Stefan Krumm, Filip Lievens, Nikola Stenzel Apr 2023

Arousing Motives Or Eliciting Stories? On The Role Of Pictures In A Picture–Story Exercise, Philipp Schäpers, Stefan Krumm, Filip Lievens, Nikola Stenzel

Research Collection Lee Kong Chian School Of Business

Picture–story exercises (PSE) form a popular measurement approach that has been widely used for the assessment of implicit motives. However, current theorizing offers two diverging perspectives on the role of pictures in PSEs: either to elicit stories or to arouse motives. In the current study, we tested these perspectives in an experimental design. We administered a PSE either with or without pictures. Results from N = 281 participants revealed that the experimental manipulation had a medium to large effect for the affiliation and power motive domains, but no effect for the achievement motive domain. We conclude that the herein chosen …


Covid Time: How Quarantine Affects Feelings Of Elapsed Time, Minju Han, Guy Voichek, Gal Zauberman Apr 2023

Covid Time: How Quarantine Affects Feelings Of Elapsed Time, Minju Han, Guy Voichek, Gal Zauberman

Research Collection Lee Kong Chian School Of Business

The lockdowns imposed in response to the COVID-19 pandemic abruptly upended people's lives and daily structure. In this survey of 1,506 Americans conducted in June 2020, we test how quarantine affects feelings of elapsed time (the subjective temporal distance from an event). We find that feelings of elapsed time are determined either by how people spent their time in quarantine or by how much time since an event was spent in quarantine, depending on whether people are still in quarantine at the time of evaluation. Specifically, whether people quarantined alone and the extent to which they maintained a temporal structure …


Liquidity Constraints, Consumption, And Debt Repayment: Evidence From Macroprudential Policy In Turkey, Sumit Agarwal, Muris Hadzic, Changcheng Song, Yildirim Yildiray Apr 2023

Liquidity Constraints, Consumption, And Debt Repayment: Evidence From Macroprudential Policy In Turkey, Sumit Agarwal, Muris Hadzic, Changcheng Song, Yildirim Yildiray

Research Collection Lee Kong Chian School Of Business

Using account-level credit card data from a large Turkish bank, we study the impact of a unique credit card policy that increases minimum payment on consumption and debt repayment. We show that the policy reduces credit card spending and debt, boosts existing debt repayment, and reduces credit card delinquency. The credit card debt of affected consumers falls on average by 50% two years into the policy’s implementation. An increase in minimum payment has a stronger effect than does a decrease of a similar magnitude. We build a benchmark life cycle model with soft liquidity constraint to explain the reduction in …


Multiple, Speeded Assessments Under Scrutiny: Underlying Theory, Design Considerations, Reliability, And Validity, Christoph N. Herde, Filip Lievens Mar 2023

Multiple, Speeded Assessments Under Scrutiny: Underlying Theory, Design Considerations, Reliability, And Validity, Christoph N. Herde, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Recently, multiple, speeded assessments (e.g., “speeded” or “flash” role-plays) have made rapid inroads into the selection domain. So far, however, the conceptual underpinning and empirical evidence related to these short, fast-paced assessment approaches has been lacking. This raises questions whether these speeded assessments can serve as reliable and valid indicators of future performance. This paper uses the notions of stimulus and response domain sampling to conceptualize multiple, speeded behavioral job simulations as a hybrid of established simulation-based selection methods. Next, we draw upon the thin slices of behavior paradigm to theorize about the quality of ratings made in multiple, speeded …


Exchange-Traded Funds And Real Investment, Constantinos Antoniou, Frank Weikai Li, Xuewen Liu, Avanidhar Subrahmanyam, Chengzhu Sun Mar 2023

Exchange-Traded Funds And Real Investment, Constantinos Antoniou, Frank Weikai Li, Xuewen Liu, Avanidhar Subrahmanyam, Chengzhu Sun

Research Collection Lee Kong Chian School Of Business

We investigate the link between exchange-traded funds and real investment. Cross-sectionally, higher ETF ownership is associated with an increased sensitivity of real investment to Tobin's q and a heightened ability of stock returns to forecast future earnings. Inclusion of stocks in industry ETFs enhances investment-q sensitivity and implies greater incorporation of earnings information into prices prior to public releases. Greater nonmarket ETF ownership leads to increased (reduced) reliance of real investment on own (peers') stock prices. Overall, the evidence is consistent with ETFs positively affecting real investment efficiency via greater flows of information.


Vehicle Rebalancing In A Shared Micromobility System With Rider Crowdsourcing, Ziliang Jin, Yulan Wang, Yun Fong Lim, Kai Pan, Zuo-Jun Max Shen Mar 2023

Vehicle Rebalancing In A Shared Micromobility System With Rider Crowdsourcing, Ziliang Jin, Yulan Wang, Yun Fong Lim, Kai Pan, Zuo-Jun Max Shen

Research Collection Lee Kong Chian School Of Business

Problem definition: Shared micromobility vehicles provide an eco-friendly form of short-distance travel within an urban area. Since customers pick up and drop off vehicles in any service region at any time, such convenience often leads to a severe imbalance between vehicle supply and demand in different service regions. To overcome this, a micromobility operator can crowdsource individual riders with reward incentives in addition to engaging a third-party logistics provider (3PL) to relocate the vehicles. Methodology/results: We construct a time-space network with multiple service regions and formulate a twostage stochastic mixed-integer program considering uncertain customer demands. In the first stage, the …
