Reproducibility In Management Science, MiloˇS Fišar, Ben Greiner, Christoph Huber, Elena Katok, Ali I. Ozkes, Hannah H. Chang Dec 2023

Reproducibility In Management Science, MiloˇS Fišar, Ben Greiner, Christoph Huber, Elena Katok, Ali I. Ozkes, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

With the help of more than 700 reviewers, we assess the reproducibility of nearly 500 articles published in the journal Management Science before and after the introduction of a new Data and Code Disclosure policy in 2019. When considering only articles for which data accessibility and hardware and software requirements were not an obstacle for reviewers, the results of more than 95% of articles under the new disclosure policy could be fully or largely computationally reproduced. However, for 29% of articles, at least part of the data set was not accessible to the reviewer. Considering all articles in our sample …


In Search Of Cryptocurrency Failure, Donglian Ma, Jun Tu, Zhaobo Zhu Dec 2023

In Search Of Cryptocurrency Failure, Donglian Ma, Jun Tu, Zhaobo Zhu

Research Collection Lee Kong Chian School Of Business

This paper explores the determinants of cryptocurrency failure and the pricing of crypto failure risk. We document different significant market- and characteristic-based predictors for coin and token failures. The introduction of Bitcoin futures and the outbreak of COVID19 affect the importance of many predictors. Investors require extra return for bearing high failure risk of crypto assets. The return difference across high and low failure risk crypto assets is not explained by the market, size and momentum factors in the cryptocurrency market. Finally, investors benefit from diversifying into high failure risk crypto assets that is little correlated with the stock market.


How Commonality Persists? (Through Investors' Sentiment And Attention), Chyng Wen Tee, Raja Velu, Zhaoque Zhou Dec 2023

How Commonality Persists? (Through Investors' Sentiment And Attention), Chyng Wen Tee, Raja Velu, Zhaoque Zhou

Research Collection Lee Kong Chian School Of Business

Studies on commonality generally attribute the variation in asset returns to the variation in order flows. In this research study, we show that order flows do not predict asset returns, rather their relationship have been static over time. Thus we model both returns and the order flows as endogenous variables, and use investors' sentiment and attention as exogenous factors via a reduced-rank regression. We provide empirical evidence to demonstrate that cross-sectional commonality in attention (sentiment) is linearly (nonlinearly) associated with both returns and order flows at the intraday level, while the sentiment and attention measures themselvesexhibit a nonlinear mutual relationship, …


Going Beyond The Call Of Duty Under Conditions Of Economic Threat: Integrating Life History And Temporal Dilemma Perspectives, Nina Sirola Nov 2023

Going Beyond The Call Of Duty Under Conditions Of Economic Threat: Integrating Life History And Temporal Dilemma Perspectives, Nina Sirola

Research Collection Lee Kong Chian School Of Business

Under conditions of economic threat, such as during economic downturns, organizations can benefit from employees’ willingness to go beyond the call of duty and engage in organization-directed citizenship behavior (OCBO). Yet, such behavior is discretionary and competes for time with employees’ other interests and priorities. I integrate life history theory with the temporal dilemma perspective on organizational citizenship behavior to propose that childhood environments sensitize individuals to prioritize different goals in response to economic threat later in life. Consistent with strategies for responding to threat that are functional in their childhood environments, employees from wealthier backgrounds respond to economic threat …


Tail Risk Hedging: The Search For Cheap Options, Poh Ling Neo, Chyng Wen Tee Nov 2023

Tail Risk Hedging: The Search For Cheap Options, Poh Ling Neo, Chyng Wen Tee

Research Collection Lee Kong Chian School Of Business

The authors find that a simple heuristic of sorting liquid equity options by dollar price to construct a portfolio of cheap put options leads to a surprisingly robust hedge for tail risk – the superior performance holds even when compared against more advanced empirical strategies. Further investigation reveals the asymmetry in market correlation under different market conditions as the mechanism of this robust hedging performance. The cheap options selected by the heuristic comprises of stocks with diverse firm characteristics. The correlation spike accompanying tail risk events leads to the majority of these put options moving into-the-money (ITM), thus compensating the …

A preregistered meta-analysis, including 244 effect sizes from 85 field audits and 361,645 individual job applications, tested for gender bias in hiring practices in female-stereotypical and gender-balanced as well as male-stereotypical jobs from 1976 to 2020. A “red team” of independent experts was recruited to increase the rigor and robustness of our meta-analytic approach. A forecasting survey further examined whether laypeople (n = 499 nationally representative adults) and scientists (n = 312) could predict the results. Forecasters correctly anticipated reductions in discrimination against female candidates over time. However, both scientists and laypeople overestimated the continuation of bias against female candidates. …

He however noted money changers still have a role to play, and shared his views on how money changers can respond to technological disruption.


Physical Frictions And Digital Banking Adoption, Hyun Soo Choi, Roger Loh Nov 2023

Physical Frictions And Digital Banking Adoption, Hyun Soo Choi, Roger Loh

Research Collection Lee Kong Chian School Of Business

The behavioral literature suggests that minor frictions can elicit desirable behavior without obvious coercion. Using closures of ATMs in a densely populated city as an instrument for small frictions to physical banking access, we find that customers affected by ATM closures increase their usage of the bank's digital platform. Other spillover effects of this adoption of financial technology include increases in point-of-sale (POS) transactions, electronic funds transfers, automatic bill payments and savings, and a reduction in cash usage. Our results show that minor frictions can help overcome the status-quo bias and facilitate significant behavior change.

Financial scandals elsewhere have shown that ‘finfluencers’ do not always act in good faith and can mislead their followers.


Rule Violation And Time-To-Enforcement In Weak Institutional Environments: A Good Faith Perspective, Jun Xia, Yusi Jiang, Heli Wang, Yuan Li Nov 2023

Rule Violation And Time-To-Enforcement In Weak Institutional Environments: A Good Faith Perspective, Jun Xia, Yusi Jiang, Heli Wang, Yuan Li

Research Collection Lee Kong Chian School Of Business

Previous studies on corporate misconduct have focused mainly on preventing misconduct or remedying it after detection, but it remains unclear how misconduct can be effectively detected in the first place once it occurs. We apply the good faith perspective in the context of China, which represents a weak institutional environment, and argue that the ability of culpable leaders to conceal information may delay misconduct disclosure because such ability helps maintain the good faith of regulators. Moreover, we argue that because the regulators have faith in professionals (external auditors, institutional investors, and securities analysts) whose skills are in fact often underdeveloped …

Tickets to popular elimination style tournaments (e.g., NFL Super Bowl) are expensive and scarce. Sports organizations sell these tickets well in advance of the final game. Fans hesitate to buy them because they are unsure about whether their favorite team will play in it. We present two alternatives to the current practice: consumer forwards and options. A fan pays a reserve price to secure her team-specific forward ticket. If that team makes it to the final game, the fan must (in the option case, has the choice to) pay an exercise price to purchase the ticket. If the team does …


Maximizing The Benefits Of An On-Demand Workforce: Fill Rate-Based Allocation And Coordination Mechanisms, Tao Lu, Zhichao Zheng, Yuanguang Zhong Nov 2023

Maximizing The Benefits Of An On-Demand Workforce: Fill Rate-Based Allocation And Coordination Mechanisms, Tao Lu, Zhichao Zheng, Yuanguang Zhong

Research Collection Lee Kong Chian School Of Business

Problem definition: With the rapid growth of the gig economy, on-demand staffing platforms have emerged to help companies manage their temporary workforce. This emerging business-to-business context motivates us to study a new form of supply chain coordination problem. We consider a staffing platform managing an on-demand workforce to serve multiple firms facing stochastic labor demand. Before demand realization, each individual firm can hire permanent employees, whereas the platform determines a compensation rate for potential on-demand workers. After knowing the realized demand, firms in need can request on-demand workers from the platform, and then, the platform operator allocates the available on-demand …


Effects Of Framing, Nomenclature, And Aversion To Tampering With Nature On Consumer Acceptance Of Cultivated Meat In Singapore, Mark Chong, Angela K. Y. Leung, Tricia M. Fernandez, Shu Tian Ng Nov 2023

Effects Of Framing, Nomenclature, And Aversion To Tampering With Nature On Consumer Acceptance Of Cultivated Meat In Singapore, Mark Chong, Angela K. Y. Leung, Tricia M. Fernandez, Shu Tian Ng

Research Collection Lee Kong Chian School Of Business

This paper comprises a qualitative (Study 1) and a quantitative phase (Study 2). Study 1 aimed to find out what frames and nomenclature would appeal most to meat eaters – including consumers who have eaten cultivated chicken – in Singapore. It also aimed to discover whether perceptions of cultivated meat's naturalness varied across different age groups. Study 2 assessed which message frame and nomenclature were most effective in fostering consumer acceptance of cultivated meat. In addition, it investigated if age was related to the perception of cultivated meat's naturalness and acceptance, and whether aversion to tampering with nature was negatively …


Immersive Retailing: The In-Store Experience, Henrik Hagtvedt, Chandukala, Sandeep R. Nov 2023

Immersive Retailing: The In-Store Experience, Henrik Hagtvedt, Chandukala, Sandeep R.

Research Collection Lee Kong Chian School Of Business

This conceptual article explores why consumers visit physical stores—despite living in a digital-first world—and presents potential ways for retailers to further encourage offline shopping. Although online retailing tends to offer the greatest convenience, brick-and-mortar outlets can offer an immersive in-store experience that combines convenience and interest. The present exposition considers store features within a 2 × 2 typology of convenience and interest and illustrates how these features contribute, or fail to contribute, to immersive in-store experiences. Other factors, such as ambient stimuli that elicit sensory- and aesthetic pleasure, provide additional paths to immersion. The notions raised may serve as a …


Formal Versus Informal Supervisor Socio-Emotional Support Behaviours And Employee Trust: The Role Of Cultural Power Distance, Jaee Cho, S. Arzu Wasti, Krishna Savani, Hwee Hoon Tan, Michael W. Morris Nov 2023

Formal Versus Informal Supervisor Socio-Emotional Support Behaviours And Employee Trust: The Role Of Cultural Power Distance, Jaee Cho, S. Arzu Wasti, Krishna Savani, Hwee Hoon Tan, Michael W. Morris

Research Collection Lee Kong Chian School Of Business

This research investigates how formal versus informal supervisor support behaviours shape employees' affect- and cognition-based trust across cultures of varying power distance. Using data from in-depth interviews, Study 1 found that trust-enhancing supervisor behaviours were more formal, status conscious and imposing in India (a high power distance culture) than in the Netherlands (a low power distance culture); unlike in India, supervisors acted more like friends or equals with their subordinates in the Netherlands. Using vignettes, Study 2 found that, compared to informal support behaviours, formal support behaviours increased both affect- and cognition-based trust among Indian participants, but among US participants, …


Deploying Business Ecosystems To Cope With Ecological Transformation, Arnoud Cyriel Leo De Meyer Nov 2023

Deploying Business Ecosystems To Cope With Ecological Transformation, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

At a time when businesses must innovate quickly and in support of sustainability, "going it alone" is no longer the most effective or efficient model. Business ecosystems – networks of companies, researchers and other stakeholders each involved in a given value chain – offer an effective route to companies seeking not only to find new advantages, but to drive wider systemic change. When innovation takes place through ecosystems, often, the results are faster to diffuse through an industry or value chain. To address needs of the ecological transformation like the transition to clean fuels, this is exactly what is needed; …

This article discusses the challenges and benefits of managing language dynamics at work, where both standard and hybrid forms of language coexist. It reviews the literature on language-related misunderstanding and its effects on employee outcomes through three pathways: relational, emotional, and informational. It also suggests some interventions to enhance communication effectiveness and foster an inclusive culture in linguistically diverse workplaces.


Conflict Or Alignment? The Role Of Return-Oriented Foreign Shareholders And Domestic Relational Shareholders In Mitigating Earnings Management, Toru Yoshikawa, Ignacio P. Requejo, Asli Colpan, Daisuke Uchida Nov 2023

Conflict Or Alignment? The Role Of Return-Oriented Foreign Shareholders And Domestic Relational Shareholders In Mitigating Earnings Management, Toru Yoshikawa, Ignacio P. Requejo, Asli Colpan, Daisuke Uchida

Research Collection Lee Kong Chian School Of Business

This study investigates the effects of foreign return-oriented shareholders and domestic relational shareholders of Japanese companies on the earnings management behavior of their invested firms when stock option pay is adopted. We theorize that foreign shareholders seek short-term returns and do not engage in close monitoring due to an information disadvantage while domestic shareholders prevent managerial behavior that distorts information disclosure. Our findings show that managers of firms that use stock option pay engage in earnings management to increase their private financial benefits and meet capital markets’ expectations, which allows them to enhance their own reputation. However, this managerial behavior …


Mitigating Industry Contagion Effects From Financial Reporting Fraud: A Competitive Dynamics Perspective Of Non-Errant Rival Firms Exploiting Product-Market Opportunities, Eugene Kang, Nongnapat Thosuwanchot, David Gomulya Nov 2023

Mitigating Industry Contagion Effects From Financial Reporting Fraud: A Competitive Dynamics Perspective Of Non-Errant Rival Firms Exploiting Product-Market Opportunities, Eugene Kang, Nongnapat Thosuwanchot, David Gomulya

Research Collection Lee Kong Chian School Of Business

Existing studies show that financial reporting frauds by errant firms cause declines in stock market valuations for non-errant rival firms (i.e. industry contagion effects). We posit that contagion effects may be mitigated by investors’ expectations of non-errant rivals exploiting product-market opportunities at the expense of errant firms. We apply the competitive dynamics literature to argue that non-errant rivals experience lower contagion effects when they have more available slack to engage in competitive actions. This effect is expected to strengthen when rival firms have previously deployed more resources for research and development and advertising investments or have higher prior market share …

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 …

Demand Pull Versus Resource Push Training Approaches To Entrepreneurship: A Field Experiment, Simone Santamaria, Niloofar Abolfathi, Ishtiag Pasha Mahmood

Research Collection Lee Kong Chian School Of Business

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 Oct 2023

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.


Consumers’ Reaction To Corporate Esg Performance: Evidence From Store Visits, Frank Weikai Li, Frank Weikai Li, Roni Michaely Oct 2023

Consumers’ Reaction To Corporate Esg Performance: Evidence From Store Visits, Frank Weikai Li, Frank Weikai Li, Roni Michaely

Research Collection Lee Kong Chian School Of Business

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 …


Competitive Categorization And Networks: Cognitive Strategic Groups, Tian Han, Abby Ghobadian, Andrew Yim, Ran Tao, Howard Thomas Oct 2023

Competitive Categorization And Networks: Cognitive Strategic Groups, Tian Han, Abby Ghobadian, Andrew Yim, Ran Tao, Howard Thomas

Research Collection Lee Kong Chian School Of Business

Technological advancement compounds the complexity of competitor identification, making it increasingly multi-front and multi-dimensional. Strategic groups are an important unit for competition analysis, typically delineated by firms' characteristic similarities or cognitive maps. Both have inadequacies - the former produces methodological artefacts, and the latter is subject to scale limitations, replicability and managers' cognitive blind spots. Hence, the need for alternatives supplementing the existing approaches. We propose a novel grouping methodology based on news co-mentions, reflecting factual corporate events, executives' and journalists' views, and environmental changes. It yields three advantages. First, news depicts interorganizational relationships, alleviating the concern that strategic groups …

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 Across Borders: A Review Of The Research On Interorganizational Trust In International Business, Tengjian Zou, Gokhan Ertug, Ilya R. P. Cuypers, Donald L. Ferrin

Research Collection Lee Kong Chian School Of Business

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 …


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.
