Promotion Architecture: A Deal Fairness Model Of Restricted Price Promotions, Shangwen Yi, David Hardisty, Dale Griffin, Thomas Allard Aug 2026

Promotion Architecture: A Deal Fairness Model Of Restricted Price Promotions, Shangwen Yi, David Hardisty, Dale Griffin, Thomas Allard

Research Collection Lee Kong Chian School Of Business

This research examines the effectiveness of two common types of restricted price promotions: threshold promotions (conditional on spending more than a threshold amount; e.g., “Get $5 off on orders of $10 or more”) and capped promotions (limited to a maximum dollar value; e.g., “Get 50% off, up to $5 per order”). Results from seven pre-registered studies, including one field study, show that threshold promotions lead to higher purchase intentions and conversion rates (but potentially lower purchase amounts) than comparable capped promotions—even though capped promotions are equivalent in maximal economic savings for the consumer—when the trigger value (the spending amount at …


Gaming The Marketplace: Consumer Opportunism And Beliefs About Societal Hierarchy, Shilpa Madan, Aparna Labroo, Constantine S. Katsikeas Aug 2026

Gaming The Marketplace: Consumer Opportunism And Beliefs About Societal Hierarchy, Shilpa Madan, Aparna Labroo, Constantine S. Katsikeas

Research Collection Lee Kong Chian School Of Business

Consumers often behave opportunistically, taking more than what fair marketplace exchange warrants (e.g., taking excess samples, returning used items). While each individual transgression may be minor, cumulatively they can undermine firm profitability. Thus, addressing consumer opportunism is an important managerial concern. We identify a novel antecedent of consumer opportunism: consumers’ acceptance of societal hierarchy (i.e., power distance belief [PDB]), including firms’ higher position in it than consumers. Nine studies (plus two supplementary studies) employing archival, correlational, and experimental data provide converging evidence that, in marketplace interactions, this belief evokes a need to feel clever (i.e., to feel smart and knowledgeable …


Cycles Of Inequality In The Marketplace: Insights From Macro, Marketer, And Consumer Perspectives, Debora V. Thompson, Amna Kirmani, Rebecca Hamilton, Andy Li, Christilene Du Plessis, Daniel Fernandes, Guillaume Johnson, Brent Mcferren, Jian Ni, Vladmir Pavlov, Francine Petersen, Lisa Scheer, Yan Vieites, Keith Wilcox Jun 2026

Cycles Of Inequality In The Marketplace: Insights From Macro, Marketer, And Consumer Perspectives, Debora V. Thompson, Amna Kirmani, Rebecca Hamilton, Andy Li, Christilene Du Plessis, Daniel Fernandes, Guillaume Johnson, Brent Mcferren, Jian Ni, Vladmir Pavlov, Francine Petersen, Lisa Scheer, Yan Vieites, Keith Wilcox

Seeking inequality via differentiation is a fundamental theme in the marketing literature: consumers derive utility from products that convey socially valued attributes, and marketers target consumers by giving them opportunities to differentiate on socially valued attributes. However, as a large body of evidence shows, inequality can reduce consumer well-being and limit economic growth. In this paper, we take a systemic view of marketplace inequality, examining the interdependence among consumers, marketers, and macro forces in shaping inequality in markets for goods and services. Our broad review of the marketing literature across ten marketing journals and a variety of subdomains within the …


The Downside Of Generosity: How Rare Giving Fosters Stronger Social Connection, Minkwang Jang, Shereen J Chaudhry, Ayelet Fishbach May 2026

The Downside Of Generosity: How Rare Giving Fosters Stronger Social Connection, Minkwang Jang, Shereen J Chaudhry, Ayelet Fishbach

Research Collection Lee Kong Chian School Of Business

Giving serves not only to benefit others and society but also to foster social connections between givers and recipients. However, more giving is not necessarily merrier. This research finds that social connection depends not only on the act of giving but also on how many others receive the gesture from the same giver. Rare givers—those who give to fewer recipients—are perceived as more socially connected to each recipient than broad givers—those who give to many (the rare giving effect). This effect emerges across diverse contexts, including interpersonal gift exchanges in both new and existing relationships and corporate donations. As a …


The Robin Hood Effect In Transgressions Against Firms: How Political Ideology Shapes Consumer Justifications, Jason D. Lin, Anat Keinan, Hannah H. Chang, Donald R. Lehmann Apr 2026

The Robin Hood Effect In Transgressions Against Firms: How Political Ideology Shapes Consumer Justifications, Jason D. Lin, Anat Keinan, Hannah H. Chang, Donald R. Lehmann

Research Collection Lee Kong Chian School Of Business

Consumer transgressions against firms involve moral violations in which consumers take advantage of loopholes in companies’ return and satisfaction-guaranteed policies or the lack of strict enforcement against password sharing, piracy, shoplifting, wardrobing, coupon stacking, promotion abuse, and fraud. Drawing on the timeless tale of Robin Hood, the legendary outlaw who stands up against injustice, the authors demonstrate that consumers use a Robin Hood justification to legitimize their transgressions against firms. Building on moral foundations theory, this research demonstrates that political ideology impacts consumers’ transgression behavior and the perceived morality of these practices. Six studies show that under certain conditions in …


The Asymmetric Effects Of Posting An Online Review On Future Spending And The Dark Side Of Solicitations, Hulya Karaman Feb 2026

The Asymmetric Effects Of Posting An Online Review On Future Spending And The Dark Side Of Solicitations, Hulya Karaman

Research Collection Lee Kong Chian School Of Business

Motivated by the prevalence of online review creation and solicitation, this paper examines whether posting an online review impacts the reviewer’s future spending on the reviewed brand. Identifying the causal effects of posting an online review is challenging because reviewers self-select into posting, making it an endogenous decision. I overcome this challenge by using randomized online review solicitations as an instrument for the endogenous treatment variable of posting an online review and establish that doing so decreases the average future spending by the reviewers on the reviewed brand. Additionally, I show that soliciting customers to post increases their propensity to …


Old Signals, New Era: Reconsidering How Customer Satisfaction And Employee Satisfaction Impact Shareholder Wealth, Cesar Zamudio, Suyun Mah, Vanitha Swaminathan Feb 2026

Old Signals, New Era: Reconsidering How Customer Satisfaction And Employee Satisfaction Impact Shareholder Wealth, Cesar Zamudio, Suyun Mah, Vanitha Swaminathan

Research Collection Lee Kong Chian School Of Business

Extant research suggests that higher levels of customer and employee satisfaction signal a firm’s competitive advantage, resulting in greater firm value. This article advances the understanding of how firms can manage customer satisfaction and employee satisfaction to increase shareholder wealth in a new environment due to the emergence of social media and a new class of retail investors. Drawing from stakeholder theory and signaling theory, we argue that inconsistency in customer satisfaction and employee satisfaction can be informative to investors and lead to greater shareholder wealth in such a new environment. Our findings demonstrate that there is a negative joint …


Fluid Agency In Ai Systems: A Case For Functional Equivalence In Copyright, Patent, And Tort, Anirban Mukherjee, Hannah H. Chang Jan 2026

Fluid Agency In Ai Systems: A Case For Functional Equivalence In Copyright, Patent, And Tort, Anirban Mukherjee, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

Modern Artificial Intelligence (AI) systems exhibit fluid agency in multi-step workflows: lacking human-like consciousness or culpability, yet they display behavior that is (i) stochastic (probabilistic and path‑dependent), (ii) dynamic (co‑evolving with user interaction), and (iii) adaptive (able to reorient across contexts). These properties generate valuable outputs but collapse attribution, irreducibly entangling human and machine inputs. Doctrines that assume traceable provenance—authorship, inventorship, and liability—fracture under this unmappability, yielding ownership gaps and moral “crumple zones.”This Article argues that only functional equivalence stabilizes doctrine under unmappability: Where provenance is indeterminate, legal frameworks should treat human and AI contributions as equivalent for allocating rights …


The Charity Capacity Curse, Shirley (Lijun) Zhang, Thomas Allard, David Hardisty, Shane Wang Jan 2026

The Charity Capacity Curse, Shirley (Lijun) Zhang, Thomas Allard, David Hardisty, Shane Wang

Research Collection Lee Kong Chian School Of Business

Can displays of charity capacity cues paradoxically harm charities' fundraising efforts? Six pre-registered studies provide evidence of a charity capacity curse whereby donors penalize charities for displaying capacity cues, such as human resources capacity, organizational capacity, and financial capacity cues. This curse occurs because donors perceive higher-capacity charities as needing less help. As donors typically donate based on need, they donate less to charities with superior capacity signals. This effect is attenuated when: (1) higher-capacity charities' needs are made salient, and (2) donors reflect on how their decision impacts end-beneficiaries. This research contributes to the literature on effective altruism and …


The Token-Effort Effect: Trivial Redemption Effort Increases Price Promotions Effectiveness, Kuangjie Zhang, Thomas Allard, Nidhi Agrawal, Rajesh Bagchi Dec 2025

The Token-Effort Effect: Trivial Redemption Effort Increases Price Promotions Effectiveness, Kuangjie Zhang, Thomas Allard, Nidhi Agrawal, Rajesh Bagchi

Research Collection Lee Kong Chian School Of Business

This research documents how introducing redemption tasks requiring a token (i.e., trivial) amount of effort—for instance, by asking the consumer to enter a promo code or solve a CAPTCHA to receive a discount—increases price promotion effectiveness compared with equivalent straight discounts (i.e., applied automatically). Eight studies (including two field experiments) and three additional Web Appendix studies provide robust evidence for the beneficial effect of token-effort requirements on redemption rates. This effect occurs because the easy-to-attain redemption task induces a high perceived return on effort. Thus, this effect only occurs when the redemption task requires token-type effort but not when it …


Over-Reliance On Aesthetics? The Appearance-Reveals-Character Lay Theory Increases Consumers’ Devaluation Of Unattractive Produce, Shilpa Madan, Krishna Savani, Gita Venkataramani Johar Dec 2025

Over-Reliance On Aesthetics? The Appearance-Reveals-Character Lay Theory Increases Consumers’ Devaluation Of Unattractive Produce, Shilpa Madan, Krishna Savani, Gita Venkataramani Johar

Research Collection Lee Kong Chian School Of Business

Approximately 40% of all produce is rejected because it appears unattractive, contributing significantly to food waste. Whereas previous research attributes this devaluation to the ugly-is-bad effect, this research identifies an important moderator of consumers’ reliance on this heuristic: the lay theory that a person’s outer appearance reveals their inner character. Specifically, consumers who believe that people’s appearances reveal their character are less willing to accept unattractive (vs. attractive) produce because they generalize their lay theory to produce and are, thus, more likely to infer that unattractive produce is of lower quality. Consumers who do not hold the lay theory do …


The Persistence Of Homophobia In Men’S Friendship Norms, Sherrie Y. Xue, Stephanie C. Lin, Christilene Du Plessis Dec 2025

The Persistence Of Homophobia In Men’S Friendship Norms, Sherrie Y. Xue, Stephanie C. Lin, Christilene Du Plessis

Research Collection Lee Kong Chian School Of Business

Across five studies and one supplementary study (five preregistered; N = 3,215 adults), we found that men, more than women, avoided shared experiences (e.g., going to the movies, sharing food) with individuals of the same gender. Furthermore, persistent societal expectations that men should be unambiguously heterosexual underpinned this pattern: Men felt more apprehensive about signaling same-gender romance in platonic relationships than women did. In turn, romantic prototypicality drove the pattern of men (more than women) avoiding shared activities, above and beyond differences in how hedonic, enjoyable, and feminine the activities were; our findings further suggested that men’s reluctance to share …


Technology Discontinuance: A Systematic Literature Review And Research Agenda, Birgit Altrichter, Sabine Benoit Nov 2025

Technology Discontinuance: A Systematic Literature Review And Research Agenda, Birgit Altrichter, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

Technology discontinuance by users who quit digital services such as social media or lose interest in their devices after a few weeks is a common phenomenon. Yet it has received little research attention; the few studies that address it are scattered across disciplines. Research into customer churn is more prevalent, but it implies switching providers rather than halting usage altogether. By moving beyond discipline-based knowledge boundaries and conducting a systematic literature review, the current article proposes a technology discontinuance framework, which details seven technology discontinuance types (overuse, overload, proficiency, disenchantment, social, circumstantial, and solution) and their drivers. For example, guilt …


Managing The Personalization Paradox: Lessons From Spotify’S Ai Dj, Anirban. Mukherjee, Hannah H. Chang, Jonathan Wibowo Nov 2025

Managing The Personalization Paradox: Lessons From Spotify’S Ai Dj, Anirban. Mukherjee, Hannah H. Chang, Jonathan Wibowo

Research Collection Lee Kong Chian School Of Business

This case study uses Spotify’s AI DJ to examine the “personalization paradox,” where product features designed to deepen user connection can instead cause alienation. An analysis of over 1,400 user comments identifies three core frictions: a perceived loss of user agency, mismanaged expectations for the human-like AI, and a scalability bottleneck that led to repetitive content. Students are placed in the role of a product manager tasked with developing a prioritized roadmap to address these issues, forcing them to grapple with the critical trade-offs between technological capability and user psychology.


Temporal Patterns Of New Product Introductions And Ipo Value: The Importance Of Recency, Dispersion, And Asymmetry, Suyun Mah, Rebecca J. Slotegraaf, Girish Mallapragada Sep 2025

Temporal Patterns Of New Product Introductions And Ipo Value: The Importance Of Recency, Dispersion, And Asymmetry, Suyun Mah, Rebecca J. Slotegraaf, Girish Mallapragada

Research Collection Lee Kong Chian School Of Business

A firm’s innovation activity is often judged by the number and type of new products it launches, but when these products are introduced may be equally important, especially before going public. This research investigates how the temporal pattern of new product introductions (NPIs) influences a firm’s initial public offering (IPO) value. The analysis uses data from 298 firms that went public between 2006 and 2023, and focuses on three patterns of timing: recency (how recently the latest product was launched before the IPO), dispersion (the degree to which NPIs before the IPO are spread out over time), and asymmetry (how …


What Values Best Distinguish The World's Cultures? The Machine Learning-Based Cultural Values Inventory, Abhishek Sheetal, Shilpa Madan, Rui Ling Lee, Krishna Savani Aug 2025

What Values Best Distinguish The World's Cultures? The Machine Learning-Based Cultural Values Inventory, Abhishek Sheetal, Shilpa Madan, Rui Ling Lee, Krishna Savani

Research Collection Lee Kong Chian School Of Business

Scientists studying culture typically focus on a small number of theoretical constructs, such as individualism–collectivism, when seeking to explain cultural differences in psychological tendencies and behaviors. However, existing theories of culture could have missed out on important constructs that are useful for explaining cross-cultural differences. We used an abductive approach combining prediction and explanation to uncover important cultural values. In the prediction phase, based on 594 attitudes, values, and beliefs included in the World Values Survey, a neural network could classify respondents’ nationalities with 90% accuracy in out-of-sample data. In the explanation phase, a feature importance analysis identified the values …

Anatomical Depiction: How Showing A Product's Inner Structure Shapes Product Valuations, Seo Yoon Kang, Junghan Kim, Arun Lakshmanan Jan 2025

Anatomical Depiction: How Showing A Product's Inner Structure Shapes Product Valuations, Seo Yoon Kang, Junghan Kim, Arun Lakshmanan

Research Collection Lee Kong Chian School Of Business

Anatomical depiction is a technique where the product is decomposed into components that are spatially arranged in a layer-by-layer manner to visually explicate its inner structure. The authors demonstrate that anatomical depiction, compared to non-anatomical depiction, enhances product valuation. This effect occurs because anatomical depiction elicits a ‘coming together’ of the inner components in consumers’ minds thereby evoking a gestalt image of the product – a process labeled simulated assemblage. The elicitation of simulated assemblage in turn boosts their confidence in the product’s performance. Two field experiments first demonstrate that anatomical depiction leads to greater engagement in online settings such …


Will Labubu Be A Keeper Like Hello Kitty And Pokémon?, Hannah H. Chang, Joy Zhang Jan 2025

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Associate Professor of Marketing Hannah Chang and Joy Zhang, a student from United World College of South East Asia, explored the unique qualities that enable certain toy fads to transcend trends and become cultural icons. They also examined the rising popularity of Labubu, offering insights into whether it has the potential to achieve enduring icon status comparable to the likes of Hello Kitty.


Predicting Personality Or Prejudice? Facial Inference In The Age Of Artificial Intelligence, Shilpa Madan, Gayoung Park Aug 2024

Predicting Personality Or Prejudice? Facial Inference In The Age Of Artificial Intelligence, Shilpa Madan, Gayoung Park

Research Collection Lee Kong Chian School Of Business

Facial inference, a cornerstone of person perception, has traditionally been studied through human judgments about personality traits and abilities based on people's faces. Recent advances in artificial intelligence (AI) have introduced new dimensions to this field, employing machine learning algorithms to reveal people's character, capabilities, and social outcomes based just on their faces. This review examines recent research on human and AI-based facial inference across psychology, business, computer science, legal, and policy studies to highlight the need for scientific consensus on whether or not people's faces can reveal their inner traits, and urges researchers to address the critical concerns …


Autonomous Stores: How Levels Of In-Store Automation Affect Store Patronage, Sabine Benoit, Birgit Altrichter, Dhruv Grewal, Carl-Philip Ahlbom Jun 2024

Autonomous Stores: How Levels Of In-Store Automation Affect Store Patronage, Sabine Benoit, Birgit Altrichter, Dhruv Grewal, Carl-Philip Ahlbom

Research Collection Lee Kong Chian School Of Business

Autonomous stores operate without needing on -site staff present to support and monitor customers. This study seeks to determine which autonomous stores are most likely to succeed. By adapting convenience theory and drawing on secondary and qualitative data, the authors identify unique features of autonomous stores that constitute convenience dimensions: options for check -in (access convenience), staff support (assistance convenience), check -out (transaction convenience), and to allow customers to check their itemized baskets (verification convenience). Perceptions of convenience, autonomy, and safety explain the influences of unique store features. A conjoint experiment provides a test of the direct effects of each …


The Science Of Creating Brand Associations: A Continuous Trinity Model Linking Brand Associations To Learning Processes, Christilene Du Plessis, Serena D'Hooge, Steven Sweldens Jun 2024

The Science Of Creating Brand Associations: A Continuous Trinity Model Linking Brand Associations To Learning Processes, Christilene Du Plessis, Serena D'Hooge, Steven Sweldens

Research Collection Lee Kong Chian School Of Business

The Continuous Trinity Model (CTM) of brand associations integrates 50 years of consumer learning research with recent conceptualizations of consciousness. Three types of brand associations are proposed at the representational level (expectations, meaning, and affect), corresponding to three types of learning at the process level (predictive learning, referential learning, and direct affect transfer). A core proposition derived from research on automaticity holds that the operating conditions of the learning processes vary on a continuum from mostly System 2 for predictive learning to mostly System 1 for direct affect transfer, with referential learning as a mix of the two. The CTM …


Untangling Influence: The Effect Of Follower-Followee Comparison On Social Media Engagement, Yi Peng, Liling Lu May 2024

Untangling Influence: The Effect Of Follower-Followee Comparison On Social Media Engagement, Yi Peng, Liling Lu

Research Collection Lee Kong Chian School Of Business

Social media platforms and marketers are keen on identifying truly influential creators. Number of followers (i.e., those who follow creators) and number of followees (i.e., those who are followed by creators) serve as cues to infer creators' influence. However, a cue of creators' actual influence is under-addressed and its effect on social media engagement remains to be explored. This research fills the gap in the literature by investigating how the cue of creators' actual influence (i.e., follower-followee comparison) may affect followers' engagement behavior. The study further examines the moderation effects of media-, topic-, and creator-related factors. The present work leverages …


The Dark Side Of Category Expansion: Will Existing Ones Pay The Price?, Qi Yu, Ron Berman, Eric Bradlow Jan 2024

The Dark Side Of Category Expansion: Will Existing Ones Pay The Price?, Qi Yu, Ron Berman, Eric Bradlow

Research Collection Lee Kong Chian School Of Business

Many retailers that manage product assortments believe that “more is better”. We challenge this conventional wisdom by demonstrating that a retailer may face more price-sensitive demand for existing categories after a category expansion. While introducing a new category to a store may increase the demand for the existing ones, this increase sometimes suggests a movement towards the steeper part of the demand curve and an increase in price sensitivity. We build a model of multi-category purchases with transportation costs and generate a series of theoretical predictions of the changes in price sensitivity after category expansion. We then estimate the model …


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


The Persuasive Effect Of Ai-Synthesized Voices, Hannah H. Chang, Anirban Mukherjee Dec 2023

The Persuasive Effect Of Ai-Synthesized Voices, Hannah H. Chang, Anirban Mukherjee

Research Collection Lee Kong Chian School Of Business

Artificial intelligence (AI) technology seeks to emulate humans. One aspect is AI-synthesized voices, used in voice assistants (such as Amazon Alexa, Apple Siri, and Google Assistant) to assistive technologies (such as voiceover narration in product videos). For example, there are currently more than 3.25 billion voice assistants; a number that is expected to touch about 8 billion by next year (i.e., 2023) (Statista 2022). With the extensive availability and enhanced accuracy of AI-synthesized voices, consumer research is starting to examine the impact of AI-synthesized voices on consumer information processing and decision making. The extant literature, however, is relatively limited because …


Leveraging In-Store Technology And Ai: Increasing Customer And Employee Efficiency And Enhancing Their Experiences, Dhruv Grewal, Sabine Benoit, Stephanie Noble, Abhijit Guha, Carl-Philip Ahlbom, Jens Nordfalt Dec 2023

Leveraging In-Store Technology And Ai: Increasing Customer And Employee Efficiency And Enhancing Their Experiences, Dhruv Grewal, Sabine Benoit, Stephanie Noble, Abhijit Guha, Carl-Philip Ahlbom, Jens Nordfalt

Research Collection Lee Kong Chian School Of Business

Due to digital innovations, retailing is undergoing radical changes. Scholars have proposed frameworks to address outcomes of implementing technology e.g., an increased customer experience, efficiency gains, consumer or employee acceptance. Existing frameworks concentrate primarily on the consumer perspective, focus on specific technologies (e.g., AI) and covering the customer journey. In contrast, this paper also focuses on the employee perspective, and how technology influences the employee journey. Since the convenience offered by online retailers puts offline retailers under pressure, this research focuses on in-store technology. Based on a comprehensive review of managerial and academic literature and expert interviews, we propose a …


Cross-Period Impatience: Subjective Financial Periods Explain Time-Inconsistent Choices, Minkwang Jang, Oleg Urminsky Dec 2023

Cross-Period Impatience: Subjective Financial Periods Explain Time-Inconsistent Choices, Minkwang Jang, Oleg Urminsky

Research Collection Lee Kong Chian School Of Business

Inconsistency in consumer time preferences has been well established and used to explain seemingly short-sighted behaviors (e.g., failures of self-control). However, prior research has conflated time-inconsistent preferences (discount rates that vary over time) with present bias (greater discounting when outcomes are delayed specifically from the present, as opposed to from a future time). This research shows that time-inconsistent preferences are reliably observed only when choices are substantially delayed (e.g., months into the future), which cannot be explained by present bias. This seeming puzzle is explained by a novel cross-period discounting framework, which predicts that consumers are more impatient when choosing …


The Dark Side Of The Sharing Economy: A Systematic Literature Review Of Externalities And Their Regulation, Mosaad Mohamed, Sabine Benoit, Chanaka Jayawardhena Nov 2023

The Dark Side Of The Sharing Economy: A Systematic Literature Review Of Externalities And Their Regulation, Mosaad Mohamed, Sabine Benoit, Chanaka Jayawardhena

Research Collection Lee Kong Chian School Of Business

As the sharing economy has grown, externalities, i.e., “dark sides,” have also surfaced. The intricacies surrounding these externalities and their regulatory measures have garnered significant scholarly interest; however, there remains a lack of comprehensive guidance on the appropriate regulatory approaches. Based on a systematic literature review of 99 papers, we provide an overview of two regulatory approaches (government and self-regulation) to address the sharing economy's economic, social, and environmental externalities affecting multiple stakeholders. We show that government regulation entails mechanisms based on avoiding, limiting, and guiding, while self-regulation entails mechanisms related to market entry, operation, and monitoring. We develop an …


Browsing The Aisles Or Browsing The App? How Online Grocery Shopping Is Changing What We Buy, Sai Chand Chintala, Jura Liaukonyte, Nathan Yang Aug 2023

Browsing The Aisles Or Browsing The App? How Online Grocery Shopping Is Changing What We Buy, Sai Chand Chintala, Jura Liaukonyte, Nathan Yang

Research Collection Lee Kong Chian School Of Business

This paper investigates the systematic differences between online and offline grocery shopping baskets using data from approximately two million brick-and-mortar and Instacart trips. We apply unsupervised machine learning algorithms agnostic to the shopping channel to identify what constitutes a typical food shopping trip for each household. We find that food shopping basket variety is significantly lower for online shopping trips as measured by the number of unique food categories and items purchased. Within a given household, the Instacart baskets are more similar to each other as compared with offline baskets with twice as many overlapping items between successive trips to …
