We compare the efficacy of two broad approaches to entrepreneurship training: a training prioritizing demand-side activities versus a training prioritizing resource-side activities. We do so by running a field experiment inside a 6-month entrepreneurship program involving 236 early-stage entrepreneurs. Inspired by our training, the first group invested more time interacting with potential customers and developing a deep understanding of customer needs and problems. The other group, in contrast, spent more time identifying and exploiting their core resources such as their network. Our results reveal that the training prioritizing demand-side activities is substantially more effective. At the end of the program, …
Do Underwriters Short-Change Corporations Issuing Bonds?, Jeremy C. Goh, Lisa (Zongfei) Yang
Do Underwriters Short-Change Corporations Issuing Bonds?, Jeremy C. Goh, Lisa (Zongfei) Yang
Research Collection Lee Kong Chian School Of Business
We confirm prior evidence that bonds on average are offered at prices below their immediate post-offer secondary market prices. However, in cases where banks lead–manage their own bond offerings the underpricing is significantly less as compared with other non-self-marketed offerings. These findings are robust across various matched samples and selection models. Our results suggest that the bond offering process is characterized by substantive agency conflicts between shareholders of corporations (issuers) and underwriters.

Using micro-level data on consumer shopping behavior, this paper investigates end-consumers’ attitudes toward firms’ ESG behavior, and as importantly, the ability of consumers to affect firms’ policy concerning sustainability issues. We find that consumers care about firms’ approach toward ESG, and consumers’ behavior can impact firms’ attitudes. Using ESG incidents as a proxy, we find that the reduction in store visits is more pronounced for ESG-conscious consumers, such as those living in democratic counties, and counties with a higher fraction of educated and younger residents. Online shopping interest data yields similar results. Using abnormally hot temperature as a shock to …
In Customer Service, When Is A Full Refund Justified?, Hannah H. Chang
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.

Trust between organizations has been recognized as crucial in international business (IB) and has attracted extensive research attention. Researchers have conceptualized and measured interorganizational trust in multiple ways, investigated numerous determinants and outcomes of interorganizational trust, and explored interorganizational trust in several types of international relationships across a range of country combinations using varied research methodologies. Our review aims to consolidate and advance this literature by focusing on (i) how interorganizational trust has been conceptualized in IB; (ii) how interorganizational trust has been operationalized in IB; (iii) what factors promote or hinder interorganizational trust in IB; (iv) what the outcomes …

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.

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 …

We use account-level transaction data to examine trading styles and profitability in a leading derivatives market. Approximately 66% of active retail investors predominantly hold simple, one-sided positions in only one class of options, whereas institutional investors are more likely to use complex strategies. Hypothesizing that the complexity of trading styles reflects investors' skills, we examine the effect of options trading styles on investment performance. We find that retail investors using simple strategies lose to the rest of the market. For both retail and institutional investors, selling volatility is the most successful strategy. We conclude that these style effects are persistent …
Is Carbon Risk Priced In The Cross-Section Of Corporate Bond Returns?, Tinghua Duan, Frank Weikai Li, Quan Wen
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, …

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
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 …

Dynamic Scheduling With Uncertain Job Types, Zuo-Jun Max Shen, Jingui Xie, Zhichao Zheng, Han Zhou
Research Collection Lee Kong Chian School Of Business
Uncertain job types can arise as a result of predictive or diagnostic inaccuracy in healthcare or repair service systems and unknown preferences in matching service systems. In this paper, we study systems with multiple types of jobs, in which type information is imperfect and will be updated dynamically. Each job has a prior probability of belonging to a certain type which may be predicted by data, models, or experts. A job can only be processed by the right machine, and a job assigned to the wrong machine must be rescheduled. More information is learned from the mismatch, and job type …

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 …

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

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 …

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 …

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 …

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 …

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 …

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 …

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
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 …
