Is Carbon Risk Priced In The Cross-Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen Sep 2023

Is Carbon Risk Priced In The Cross-Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen

Research Collection Lee Kong Chian School Of Business

This paper examines the pricing of a firm's carbon risk, measured by its carbon emissions intensity, in the cross-section of corporate bond returns. Contrary to the "carbon risk premium" hypothesis, we find bonds of firms with higher carbon emissions intensity earn significantly lower returns. This effect cannot be explained by a comprehensive list of bond characteristics and exposure to known risk factors. Investigating sources of the low carbon premium, we find the underperformance of bonds issued by carbon-intensive firms cannot be fully explained by divestment from institutional investors. Instead, our evidence is most consistent with investor underreaction to carbon risk, …


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 …


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 …


Shrinking Factor Dimension: A Reduced-Rank Approach, Ai He, Dashan Huang, Jiaen Li, Guofu Zhou Sep 2023

Shrinking Factor Dimension: A Reduced-Rank Approach, Ai He, Dashan Huang, Jiaen Li, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

We propose a reduced-rank approach (RRA) to reduce a large number of factors to a few parsimonious ones. In contrast to PCA and PLS, the RRA factors are designed to explain the cross section of stock returns, not to maximize factor variations or factor covariances with returns. Out of 70 factor proxies, we find that five RRA factors outperform the Fama-French (2015) five factors for pricing target portfolios, but performs similarly for pricing individual stocks. Our results suggest that existing factor proxies do not provide enough new information at the stock level beyond the Fama-French (2015) five factors.


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 …


The Information In Asset Fire Sales, Sheng Huang, Matthew C. Ringgenberg, Zhe Zhang Sep 2023

The Information In Asset Fire Sales, Sheng Huang, Matthew C. Ringgenberg, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

Asset prices remain depressed for years following mutual fund fire sales, but little is known about the causes of these price drops. We show that asymmetric information generates price pressure during fire sales. We separate trades into expected trades, which assume fund managers scale down their portfolio, and discretionary trades. We find that discretionary trades contain fundamental information, whereas expected trades do not. Moreover, other traders cannot distinguish between discretionary and expected trades. Our findings help explain the magnitude and persistence of fire sale discounts: fund managers choose which assets to sell, and information asymmetries make it difficult for arbitrageurs …


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 …


Of Headlamps And Marbles: A Motivated Perceptual Approach To The Dynamic And Dialectic Nature Of Fairness, Michael Ramsay Bashshur, Laurie J. Barclay, Marion Fortin Sep 2023

Of Headlamps And Marbles: A Motivated Perceptual Approach To The Dynamic And Dialectic Nature Of Fairness, Michael Ramsay Bashshur, Laurie J. Barclay, Marion Fortin

Research Collection Lee Kong Chian School Of Business

How do people perceive fairness? Recently, fairness scholars have raised important theoretical questions related to what information is used in fairness perceptions, why this information is emphasized, and how fairness perceptions can change over time. Integrating the Brunswikian lens approach with a motivated cognition perspective, we develop the Motivated Perceptual Approach (MPA) to highlight how people can be motivated to selectively perceive and weight cues to form fairness perceptions that align with their motives. However, these motives can change over time and through interaction with motivated others. By illuminating the dynamic and dialectic processes underlying fairness perceptions, the MPA sheds …

Research Collection Lee Kong Chian School Of Business

The authors dive deep into the field of ReFi, a concept that enhances financial practices through decentralization and focuses on environmental and societal systems. The authors highlight several key problems of the space and point out that genuinely disruptive ReFi models are still in their infancy. The good news is that ReFi’s potentials are manifold and exciting. In the not-too-distant future, we might see financial applications backed by blockchain that can enhance data credibility, exchangeability, and transparency to redefine how corporations create and apportion environmental value.


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 …


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 …


The Effect Of Nationalism On Governance Choices In Cross-Border Collaborations, Gokhan Ertug, Ilya R. P. Cuypers, Douglas Dow, Jesper Edman Aug 2023

The Effect Of Nationalism On Governance Choices In Cross-Border Collaborations, Gokhan Ertug, Ilya R. P. Cuypers, Douglas Dow, Jesper Edman

Research Collection Lee Kong Chian School Of Business

We examine how nationalism influences governance choice in cross-border collaborations. While nationalism has historically been within the purview of political scientists, we demonstrate its relevance to management scholars by theorizing how nationalist attitudes and behaviors among decision-makers might shape strategic decisions about collaborations with foreign partners. Drawing on insights from the social psychology literature, we theorize how two attitudes commonly associated with nationalism, i.e., lower levels of trust and an unwillingness to work with foreigners, may increase decision-makers’ concerns about opportunistic behavior and invasiveness in cross-border collaborations. Integrating these insights into two key theories of governance choice, i.e., transaction cost …


Heterogeneous Adaptability: Learning, Cash Resources, And The Fine-Grained Adjustment Of Misaligned Governance, Xavier Martin, Ilya Cuypers Aug 2023

Heterogeneous Adaptability: Learning, Cash Resources, And The Fine-Grained Adjustment Of Misaligned Governance, Xavier Martin, Ilya Cuypers

Research Collection Lee Kong Chian School Of Business

Research Summary: When can a firm make fine-grained adjustments to misaligned subsidiary governance? We examine whether and under what conditions a firm will adapt the equity stake it owns in a subsidiary, enabling improved alignment of the stake with the uncertainty in the local environment. We predict that the rate of adaptation of misaligned equity stakes depends on the experiential and vicarious learning from which the firm can draw, and that these learning effects are contingent on possessing fungible slack resources, specifically cash. Using a sample of 726 Japanese-foreign subsidiaries established in 38 host countries over a 21-year period, we …

The Race To Regeneration: A New Era For Business And Planet, Simon J.D. Schillebeeckx, Ryan Knowles Merrill

Research Collection Lee Kong Chian School Of Business

In an era where the urgency to address environmental and social challenges is paramount, traditional sustainability efforts are no longer enough. Unlike legacy sustainability strategies that revolve around measuring and reducing carbon footprints, regenerative sustainability widens its lens to encompass all facets of our planet’s well-being and focuses on creating positive impact.


Subcontracting And Rework Cost Sharing In Engineering-Procurement-Construction Projects, Zhenzhen Chen, Wanshan Zhu, Pascale Crama Aug 2023

Subcontracting And Rework Cost Sharing In Engineering-Procurement-Construction Projects, Zhenzhen Chen, Wanshan Zhu, Pascale Crama

Research Collection Lee Kong Chian School Of Business

Infrastructure development projects are overwhelmingly managed through engineering–procurement–construction (EPC) contracts, which allow a project end user to shift all project risks to a contractor. Accordingly, the International Federation of Consulting Engineers recommended a contract template based on a lump-sum contract between the end user and main contractor. However, EPC projects often suffer from quality issues due to moral hazard, which is aggravated by the involvement of subcontractors hired by the main contractor to perform parts of the project. Besides, costly rework is frequently needed to achieve the contractually mandated quality. When the main contractor must share some of the subcontractor’s …

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.


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 …

More Voices Persuade: The Attentional Benefits Of Voice Numerosity, Hannah H. Chang, Anirban Mukherjee, Amitava Chattopadhyay

Research Collection Lee Kong Chian School Of Business

The authors posit that in an initial exposure to a broadcast video, hearing different voices narrate (in succession) a persuasive message encourages consumers’ attention and processing of the message, thereby facilitating persuasion; this is referred to as “the voice numerosity effect.” Across four studies (plus validation and replication studies)—including two large-scale, real-world datasets (with more than 11,000 crowdfunding videos and over 3.6 million customer transactions, and more than 1,600 video ads) and two controlled experiments (with over 1,800 participants)—the results provide support for the hypothesized effect. The effect (1) has consequential, economic implications in a real-world marketplace, (2) is more …


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 …

Bayesian Optimization With Switching Cost: Regret Analysis And Lookahead Variants, Peng Liu, Haowei Wang, Wei Qiyu Aug 2023

Bayesian Optimization With Switching Cost: Regret Analysis And Lookahead Variants, Peng Liu, Haowei Wang, Wei Qiyu

Research Collection Lee Kong Chian School Of Business

Bayesian Optimization (BO) has recently received increasing attention due to its efficiency in optimizing expensive-to-evaluate functions. For some practical problems, it is essential to consider the path-dependent switching cost between consecutive sampling locations given a total traveling budget. For example, when using a drone to locate cracks in a building wall or search for lost survivors in the wild, the search path needs to be efficiently planned given the limited battery power of the drone. Tackling such problems requires a careful cost-benefit analysis of candidate locations and balancing exploration and exploitation. In this work, we formulate such a problem as …


Correcting For Range Restriction In Meta-Analysis: A Reply To Oh Et Al. (2023), Paul R. Sackett, Christopher M. Berry, Filip Lievens, Charlene Zhang Aug 2023

Correcting For Range Restriction In Meta-Analysis: A Reply To Oh Et Al. (2023), Paul R. Sackett, Christopher M. Berry, Filip Lievens, Charlene Zhang

Research Collection Lee Kong Chian School Of Business

Oh et al. (2023) question a number of choices made in our article (Sackett et al., 2022); here we respond. They interpret our article as recommending against correcting for range restriction in general in concurrent validation studies; yet, we emphasize that we endorse correction when one has access to the information needed to do so. Our focus was on making range restriction corrections when conducting meta-analyses, where it is common for primary studies to be silent as to the prior basis for selection of the employees later participating in the concurrent validation study. As such, the applicant pool information needed …


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 …

Not A Box Of Nuts And Bolts: Distribution Channels For Specialty Drugs?, Liang Xu, Vidya Mani, Hui Zhao Jul 2023

Not A Box Of Nuts And Bolts: Distribution Channels For Specialty Drugs?, Liang Xu, Vidya Mani, Hui Zhao

Research Collection Lee Kong Chian School Of Business

One of the most important trends in the pharmaceutical industry is the rapid growth of specialty drugs. Specialty drugs, mostly bio based, tend to be high risk, high priced, and more regulated than traditional drugs, resulting in unprecedented challenges in distribution. Such challenges lead to the emergence of specialty distributors (SDs), which, compared with traditional wholesalers (WSs), represent a more controlled channel and carry a smaller variety of drugs. Due to the risky nature of specialty drugs, manufacturers must consider the trade-off between access and control in determining whether to use SDs (partially or exclusively). Using a unique dataset assembled …

Board Governance Of Strategic Change: An Assessment Of The Literature And Avenues For Future Research, Patricia Klamer, Qiwen Yu, Toru Yoshikawa, Michael Hitt

Research Collection Lee Kong Chian School Of Business

Boards of directors play a central role in governing corporate strategic change. We systematically review corporate governance research on strategic change published over the past 40 years, differentiating between strategic change types and board characteristics. We identify three developments: a focus on specific strategic change types, board composition and structure, and North American listed firms as a dominant study context. Yet, our analysis of the literature shows that research on board governance of interrelated strategic changes, on different board roles and behaviour, and on the governance of strategic changes across different contexts remains underdeveloped. To address these research gaps, we …


Perspectives On The Impact, Mission And Purpose Of The Business School, Howard Thomas Jul 2023

Perspectives On The Impact, Mission And Purpose Of The Business School, Howard Thomas

Research Collection Lee Kong Chian School Of Business

The business school has been an important success story in the evolution of the modern university. The concept of how the impact, mission, purpose, and value of a management school should be formulated is often delegated to the dean, faculty and advisory committees in most schools. The British Academy has contributed significantly to the emerging debate on the purpose of a business school by both examining the concept of a purposeful business school in business and management education and, more recently, investigating what, and how, business schools should teach, grow and develop. Greater attention has been directed towards developing more …


Business Schools Should Be Schools Of Management: An Evolutionary Perspective, Kai Peters, Howard Thomas Jul 2023

Business Schools Should Be Schools Of Management: An Evolutionary Perspective, Kai Peters, Howard Thomas

Research Collection Lee Kong Chian School Of Business

This chapter looks at the original driving forces which led to the creation of institutions, particularly in the US, including the vision of their founders which would support our perspective in favour of schools of management. It looks at the years following the Second World War and how the Ford and Carnegie ‘Foundation Reports’ as well as the Cold War led to further evolution away from a school of management to a business school mission. The chapter looks at the period roughly from 1970 to 2000 during which US business school funding, which had been largely provided by the foundations, …


Inventory-Responsive Donor-Management Policy: A Tandem Queueing Network Model, Taozeng Zhu, Nicholas Teck Boon Yeo, Sarah Yini Gao, Gar Goei Loke Jul 2023

Inventory-Responsive Donor-Management Policy: A Tandem Queueing Network Model, Taozeng Zhu, Nicholas Teck Boon Yeo, Sarah Yini Gao, Gar Goei Loke

Research Collection Lee Kong Chian School Of Business

Problem definition: In the blood-donor-management problem, the blood bank incentivizes donors to donate, given blood inventory levels. We propose a model to optimize such incentivization schemes under the context of random demand, blood perishability, observation period between donations, and variability in donor arrivals and dropouts. Methodology/results: We propose an optimization model that simultaneously accounts for the dynamics in the blood inventory and the donor’s donation process, as a coupled queueing network. We adopt the Pipeline Queue paradigm, which leads us to a tractable convex reformulation. The coupled setting requires new methodologies to be developed upon the existing Pipeline Queue framework. …


Managing The Creative Frontier Of Generative Ai: The Novelty-Usefulness Tradeoff, Anirban. Mukherjee, Hannah H. Chang Jul 2023

Managing The Creative Frontier Of Generative Ai: The Novelty-Usefulness Tradeoff, Anirban. Mukherjee, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

In this paper, drawing inspiration from the human creativity literature, we explore the optimal balance between novelty and usefulness in generative Artificial Intelligence (AI) systems. We posit that overemphasizing either aspect can lead to limitations such as hallucinations and memorization. Hallucinations, characterized by AI responses containing random inaccuracies or falsehoods, emerge when models prioritize novelty over usefulness. Memorization, where AI models reproduce content from their training data, results from an excessive focus on usefulness, potentially limiting creativity. To address these challenges, we propose a framework that includes domain-specific analysis, data and transfer learning, user preferences and customization, custom evaluation metrics, …
