Can Big Data Cure Risk Selection In Healthcare Capitation Program? A Game Theoretical Analysis, Zhaowei She, Turgay Ayer, Daniel Montanera

Research Collection Lee Kong Chian School Of Business

Problem definition: This paper analyzes a market design problem in Medicare Advantage (MA), the largest risk-adjusted capitation payment program in the U.S. healthcare market. Evidence exists that the current MA capitation payment program unintentionally incentivizes health plans to cherry pick profitable patient types, which is referred to as “risk selection”. However, the root causes of the risk selection are not comprehensively understood, which we study in this paper. Academic / Practical Relevance: The existing literature primarily attributes the observed risk selection in MA market to data limitations and low explanatory power (e.g. low R2) of the current risk adjustment design. …

Avoiding Bias In The Search For Implicit Bias, Wilson Cyrus-Lai, Warren Tierney, Christilene Du Plessis, My Nguyen, Michael Schaerer, Elena Giulia Clemente, Eric Luis Uhlmann

Research Collection Lee Kong Chian School Of Business

To revitalize the study of unconscious bias, Gawronski, Ledgerwood, and Eastwick (this issue) propose a paradigm shift away from implicit measures of intergroup attitudes and beliefs. Specifically, researchers should capture discriminatory biases and demonstrate that participants are unaware of the influence of social category cues on their judgments and actions. Individual differences in scores on implicit measures will be useful to predict and better understand implicitly prejudiced behaviors, but the latter should be the collective focus of researchers interested in unconscious biases against social groups.

The Road To A Human-Centred Digital Society: Opportunities, Challenges And Responsibilities For Humans In The Age Of Machines, David De Cremer, Devesh Narayanan, Andreas Deppeler, Mahak Nagpal, Jack Mcguire

Research Collection Lee Kong Chian School Of Business

The growing adoption of intelligent technologies has brought us to a crossroad. The creators of intelligent technologies are acquiring the power to influence a wide variety of outcomes that are important to human end-users. In doing so, those same intelligent technologies are being used to undermine and even actively harm the interests of those same end-users. In the absence of a recalibration, we are almost certainly headed down a path wherein intelligent technologies will primarily serve the interests of developers and owners of technology rather than humankind at large. In an attempt to push for such a recalibration, we present …

Tourgether360: Collaborative Exploration Of 360° Videos Using Pseudo-Spatial Navigation, Kartikaeya Kumar, Lev Poretski, Jianan Li, Anthony Tang

Research Collection School Of Computing and Information Systems

Collaborative exploration of 360 videos with contemporary interfaces is challenging because collaborators do not have awareness of one another's viewing activities. Tourgether360 enhances social exploration of 360° tour videos using a pseudo-spatial navigation technique that provides both an overhead "context" view of the environment as a minimap, as well as a shared pseudo-3D environment for exploring the video. Collaborators are embodied as avatars along a track depending on their position in the video timeline and can point and synchronize their playback. We evaluated the Tourgether360 concept through two studies: first, a comparative study with a simplified version of Tourgether360 with …

Ethical Branding In A Divided World: How Political Orientation Motivates Reactions To Marketplace Transgressions, Thomas Allard, Brent Mcferran

Research Collection Lee Kong Chian School Of Business

In today's marketplace, users (e.g., purchasers, influencers) are increasingly the “face” of brands to potential consumers, increasing the risk for brands should these users act poorly. Across seven studies, we document that political orientation moderates the desire for punishment toward users of ethical (vs. conventional) brands who commit moral transgressions. In response to identical marketplace transgressions, we observe that liberals punish ethical brand users less than conventional brand users. In contrast, conservatives punish the same users of ethical brands more than conventional brand users. We document that this bias stems from how people interpret the inconsistency between the ethical branding …

Commonality In Credit Spread Changes: Dealer Inventory And Intermediary Distress, Zhiguo He, Paymon Khorrami, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

Two intermediary-based factors—a corporate bond dealer inventory measure and a broad intermediary distress measure—explain more than 40% of the puzzling common variation in credit spread changes beyond canonical structural factors. A simple intermediary-based model with partial market segmentation accounts for intermediary factors’ explanatory power and delivers three further implications with empirical support. First, whereas bond sorts on risk-related variables produce monotonic loading patterns on intermediary factors, non-risk-related sorts produce no pattern. Second, dealer inventory comoves with corporate-credit assets only, whereas intermediary distress comoves with both corporate-credit and non-corporate-credit assets. Third, dealers’ inventory responds to (instrumented) bond sales by institutional investors.

Riding Off Into The Sunset: Dual-Class Structure In The Age Of Unicorns Going Public, Hao Liang, Junho Park, Wei Zhang

Research Collection Lee Kong Chian School Of Business

The increasing adoption of dual-class shares (DCS)—an ownership structure that gives corporate insiders greater voting power than other shareholders—among newly listed companies has raisedsignificant governance concerns. We investigate the decision to adopt the DCS structure and itsvalue implications in the recent U.S. IPOs. Using founder cultural traits and Silicon Valley lawfirms as instrumental variables, we find significant post-IPO outperformance by firms adopting DCSwith a sunset clause, especially incapacity-based sunset which stipulates that the DCS will ceaseafter founders’ death, incapacitation or departure, compared to non-DCS firms and DCS firms without sunsets. This outperformance is more pronounced for high-tech firms, after Google’s …

Made In Singapore, Pao-Li Chang, Tran Bao Phuong Nguyen

Research Collection School Of Economics

In this paper, we characterize the position of Singapore in global value chains and identify Singapore’s key upstream and downstream trade partners. We trace how the position of Singapore in global value chains has changed in the past two decades: whether it has moved upstream or downstream, how involved it is in global value chains, how its trend compares with the other major Asian exporters (China, Japan, Korea, Taiwan and Hong Kong), and which key sectors of Singapore play a major role in these global trade networks.

Impact Of Geographical Diversification And Limited Attention On Private Equity Fund Returns, Victor Hock Keong Ong

Dissertations and Theses Collection (Open Access)

This study analyzes the effect of geographical diversification on global private equity (PE) fund returns. I find that there is a negative correlation between geographical diversification and PE fund returns. To establish the causality between geographical diversification and PE fund returns, I employ an instrument variable analysis where the instrument used is the stock market capitalization value of the host country where the PE fund is based. My results apply to Net IRR, multiple and DPI as dependent variables used to proxy for PE fund returns in the main regression model. A one standard deviation increase in geographical diversification results …

An Est Approach To Entrepreneurial Exit In Chinese Family Business: A Case Study Of H Company, Lidian Zhang

Dissertations and Theses Collection (Open Access)

Previous entrepreneurial exit literature has mostly followed a feature-oriented logic by summarizing the impact of industry and company characteristics and entrepreneurs’ personal traits on entrepreneurial exit decisions, disregarding the decision-making process of entrepreneurial exit and the role of key events in advancing the process. This thesis endeavors to explore the determining factors behind entrepreneurial exit decisions of family businesses and the dynamic decision-making process based on Event System Theory (EST) with a single-case study method and a feature-oriented and process-oriented approach.

This study has conducted an in-depth investigation into Company H, which possesses typical features of Chinese private family businesses. …

Cfo Gaps: Determinants And Impact On The Corporate Information Environment, Xia Chen, Na Li, An-Ping Lin

Research Collection School Of Accountancy

A CFO gap arises when the CFO position is left vacant for a period between the departure of the old CFO and the appointment of a new CFO. We find that CFO gaps are fairly common; over the sample period 2004–2016, approximately one-third of CFO turnovers are associated with a CFO gap, lasting on average two quarters and two months. CFO gaps are more likely for firms that face more labor market search frictions and with financial reporting and performance issues, and are less likely for firms with succession plans and with greater growth opportunities. While CFO gaps are not …

Making Virtual Project-Based Learning Work During The Covid-19 Pandemic, Yuanto Kusnadi, Gary Pan, Shankararaman, Venky

Research Collection School Of Accountancy

Project-based learning is an increasingly popular pedagogical approach in university education shown to be effective in fostering problem-solving, analytical, design thinking and teamwork skills. The COVID-19 pandemic has led to universities pivoting from project-based learning (PBL) in the classroom to a virtual learning environment. By examining local student consulting courses conducted virtually in a Singapore University (UNIS) during the COVID-19 pandemic, this study aims to address the knowledge gap in the PBL literature by identifying the roles played by digital literacy - in utilising the digital tools that support virtual learning, in a virtual learning environment. The study also serves …

That's Important, Interesting, And Generative: Winners Of The Amj 2021 Best Paper Award And Research Impact Award, Jennifer Howard-Grenville, Gurneeta Vasudeva, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

Management scholars have long been encouraged to pursue interesting research that causes us to think differently about topics or offers counterintuitive explanations (Colquitt & George, 2011; Davis, 1971). Laszlo Tihanyi, as editor in chief for AMJ, warned of “the potential trade-offs between writing interesting versus important research” in his second FTE (Tihanyi, 2020: 329). He called for “studying problems that are not merely interesting but are relevant to society,” in other words: important. It is fitting, then, that this FTE celebrates and explores our two latest award-winning papers, “The hidden cost of prayer: Religiosity and the gender wage gap” (Sitzmann …

A Consumer Perspective On Managing The Consequences Of Chain Liability, Julia Hartmann, Sebastian Forkmann, Sabine Benoit, Stephan C. Henneberg

Research Collection Lee Kong Chian School Of Business

Consumers tend to hold a focal firm responsible for its suppliers' unsustainable practices (chain liability), suggesting that firms need effective responses that can mitigate negative consumer reactions. In applying psychological contract theory to investigate recovery efforts related to such chain liability, the current study addresses three broad focal firm responses: Do nothing, choose a nonsubstantive response that verbally clarifies its own and the supplier's roles in the incident, or substantively rectify the supplier's wrongdoing with sustainability-focused responses, such as termination, monitoring or development. With a vignette-based experiment, we examine consumer perceptions and behaviors in three stages: before the unsustainable supplier …

The Differential Effects Of Csr And Csi On Consumer Willingness To Pay: Implications For Service Providers And Retailers, Sabine Benoit, Julia Hartmann, Christina Sichtmann, Martin Wetzels

Research Collection Lee Kong Chian School Of Business

Service providers and retailers reselling branded have the discretion to set and adapt prices according to customers’ willingness to pay (WTP). Research often notes markup effects, such that WTP increases in response to corporate social responsibility (CSR) and markdown effects, lowering their WTP for corporate social irresponsibility (CSI). Theory suggests attitude changes to (negative) CSI are stronger than to (positive) CSR, but the extent and whether this difference holds for WTP and across various product types are unknown. Using experimental data, an incentive-compatible measure, and an actual purchase, this article reports on three studies that show that consumers mark up …

Innovation In The Sharing Economy: A Framework And Future Research Agenda, Sabine Benoit, Yonggui Wang, Lefa Teng, Daniel P. Hampson, Xia Li

Research Collection Lee Kong Chian School Of Business

The sharing economy (SE) has been variously described as a disruptive, discontinuous, and social innovation. Now, more than a decade since the emergence of seminal platforms such as Airbnb, and amid heightened competition and macroenvironmental pressures, service innovation has become a strategic priority. Our editorial essay is guided by three objectives. First, as a prelude to this Special Issue, we examine the current state of SE service innovation literature. Despite some important contributions, especially in relation to business model innovation, other salient types of service innovation remain underexplored. Second, we position the contributions of the 13 papers in this Special …

Preservation Technology Investment And Carbon Abatement Strategies In A Supplier-Retailer Cold Chain Based On A Differential Game, Xueli Ma, Ying Zhao, Qian Luo, Qingguo Bai

Research Collection Lee Kong Chian School Of Business

Against the background of a low-carbon economy and the rising environmental awareness, extensive attention has been paid to carbon emissions in the cold chain in academic research and practice. In cold chain operations, consumers’ preference for freshness is also growing, which motivates the investment in preservation technology to improve the freshness of perishable products. However, further investment in preservation technology also increases carbon emissions. Considering these idiosyncratic features in cold chains, we apply a differential game model to examine cold chain members’ preservation technology investment and carbon abatement behaviors from a long-term horizon and dynamic perspective. The equilibrium strategies of …

Misunderstood Menu Metrics: Side-Length Food Sizing Leads To Quantity Underestimation And Overeating, Thomas Allard, Stefano Puntoni

Research Collection Lee Kong Chian School Of Business

This research highlights consumers' failure to understand food sizing communicated using side-length metrics (e.g., 12-inch pizza, 8-inch cake, 2-inch cookie), which are ubiquitous in menus and online interfaces. A series of studies show that describing food size options using side-length metrics leads to food quantity underestimation and food intakes misaligned with consumers' objectives. This robust effect arises because of a linearization heuristic where people do not adequately adjust for the exponential difference in the surface area associated with linear changes in side-length metrics. Choice architecture interventions that replace side-length information with metrics varying linearly with quantities (e.g., surface area, numbers …

Artificial Intelligence, Consumers, And The Experience Economy, Hannah H. Chang, Anirban Mukherjee

Research Collection Lee Kong Chian School Of Business

The term Artificial Intelligence (AI) was first used by McCarthy, Minsky, Rochester, and Shannon in a proposal for a summer research project in 1955 (Solomonoff, 1985). It is widely and commonly defined to be “the science and engineering of making intelligent machines” (McCarthy, 2006). Recent technological advances and methodological developments have made AI pervasive in new marketing offerings, ranging from self-driving cars, intelligent voice assistants such as Amazon’s Alexa, to burger-making robots at restaurants and rack-moving robots inside warehouses such as Amazon’s family of robots (Kiva, Pegasus, Xanthus) and delivery drones. There is optimism, and perhaps even over-optimism, of the …

Using Machine Learning To Extract Insights From Consumer Data, Hannah H. Chang, Anirban Mukherjee

Research Collection Lee Kong Chian School Of Business

Advances in digital technology have led to the digitization of everyday activities of billions of people around the world, generating vast amounts of data on human behavior. From what people buy, to what information they search for, to how they navigate the social, digital, and physical world, human behavior can now be measured at a scale and level of precision that human history has not witnessed before. These developments have created unprecedented opportunities for those interested in understanding observable human behavior–social scientists, businesses, and policymakers—to (re)examine theoretical and substantive questions regarding people’s behavior. Moreover, technology has led to the emergence …
