Moving Beyond Entry Modes: Toward A New Paradigm Of International Involvement In An Era Of Digitalization And Global Transitions, Noman Shaheer, Sali Li, Liang Chen, Keith D. Brouthers, Dan Li, Peter Liesch Jun 2026

Moving Beyond Entry Modes: Toward A New Paradigm Of International Involvement In An Era Of Digitalization And Global Transitions, Noman Shaheer, Sali Li, Liang Chen, Keith D. Brouthers, Dan Li, Peter Liesch

Research Collection Lee Kong Chian School Of Business

We seek to reconceptualize internationalization strategy by shifting focus from static, single-entry mode choices to dynamic constellations of multiple involvement modes. In an era of rapid technological change enabled by artificial intelligence, blockchain, and robotics, geopolitical volatility fueled by trade wars and violent conflicts, and increasing sustainability demands, multinational corporations (MNCs) need to rethink how they are involved with diverse stakeholder expectations, prioritize flexibility and reversibility, and embed co-creation and legitimacy alongside efficiency. Extending Brouthers et al. (2022), we integrate transaction cost economics with resource-based, institutional, opportunity, and ecosystem perspectives to explain how MNCs configure and reconfigure various constellations of …


Attention To Detail: How Do Information Users Process Exhibits In Form 10-K?, Stephanie F. Cheng, Yimeng Li, Pengkai Lin Jun 2026

Attention To Detail: How Do Information Users Process Exhibits In Form 10-K?, Stephanie F. Cheng, Yimeng Li, Pengkai Lin

Research Collection School Of Accountancy

Form 10-K offers a setting for studying how users process complex, multi-layered disclosures: managerial narratives in the main file alongside separate exhibits, such as contracts and certifications, that provide unfiltered detail. Drawing on rational inattention theory, we investigate how users allocate limited attention across these components. Users typically begin with the main file and selectively access exhibits when the main file appears shorter, less readable, or less confident, indicating higher perceived information loss. This pattern strengthens for exhibits that offer more detail on topics discussed in the main file and among institutional investors and time-constrained users. Exhibit access persists beyond …


From Gaming To Politics: The Impact Of Political Chatter By Social Media Influencers On Consumer Engagement With Non-Political Content, Mahdi Niknejad Moghadam Jun 2026

From Gaming To Politics: The Impact Of Political Chatter By Social Media Influencers On Consumer Engagement With Non-Political Content, Mahdi Niknejad Moghadam

Marketing Faculty Publications and Presentations

Social media influencers (SMIs) have become integral to digital marketing, shaping consumer perceptions and promoting products and services. While some SMIs are dedicated to political content or develop such content occasionally, nonpolitical SMIs may also engage in political chatter within their usual content. This study examines the effects of such chatter on consumer engagement by focusing on gaming SMIs. The main analysis is based on a dataset of 43,892 videos from 200 SMIs. The findings indicate that, overall, political chatter intensity in non-political content negatively impacts user engagement. However, this adverse effect is mitigated when SMIs express negative emotions, i.e., …


“Megadeal” Subsidies, Local Spillovers And Corporate Innovation, Yoojin Lee, Shaphan Ng, Aruhn Venkat Jun 2026

“Megadeal” Subsidies, Local Spillovers And Corporate Innovation, Yoojin Lee, Shaphan Ng, Aruhn Venkat

Research Collection School Of Accountancy

We examine whether the largest place-based, firm-specific corporate subsidies (“Megadeals”) awarded by state and local governments affect local firms’ innovation. First, we document that 1) subsidy firms innovate in the subsidized county and 2) subsidy firms bring inventors from other counties into the subsidized county, consistent with subsidy firms generating new knowledge locally. In our main test, we use a stacked cohort design with stringent fixed effects to document that local firms increase patenting following a Megadeal. Cross-sectionally, effects are increasing 1) in subsidy firm innovativeness, 2) in the technological closeness of subsidy firms and local firms, 3) when subsidy …

Patent Analyses And Technology Forecasting: Advances Into Artificial Intelligence Technologies, Sarah Over, Emma Jiren Wang, M. Shehryar Khan Jun 2026

Patent Analyses And Technology Forecasting: Advances Into Artificial Intelligence Technologies, Sarah Over, Emma Jiren Wang, M. Shehryar Khan

Journal of the Patent and Trademark Resource Center Association

For several decades, patents have been utilized in analyzing technology and forecasting future trends. Historically, this has been done via keywords, citations, and some bibliometric approaches. The efficiency that is promised by artificial intelligence (AI), machine learning, natural language processing, and related technologies has also heavily entered the domain of intellectual property. There is a growing body of research that is using AI technologies to analyze, learn, and make predictions for patents. Some of the most common applications in practice are those that assist searchers and examiners in review of patents. Journals such as World Patent Information have even developed …


Hallucinations And Hits: Generative Ai Patent Searching Performance, Pitfalls, And Library Best Practices, Aidan J. Whitlock, Denise A. Wetzel Jun 2026

Hallucinations And Hits: Generative Ai Patent Searching Performance, Pitfalls, And Library Best Practices, Aidan J. Whitlock, Denise A. Wetzel

Journal of the Patent and Trademark Resource Center Association

One of the most challenging aspects for inventors seeking to obtain a patent is conducting an effective preliminary prior art search. The process requires specialized skills and experience to assess the relevant information that many novice inventors do not possess. However, artificial intelligence (AI) tools and Large Language Models (LLMs) offer potential new ways of accessing legal and technical expertise. This study surveys five popular publicly available LLMs ability to aid in conducting a preliminary prior art search. A list of best practices and strategies for using AI tools to conduct preliminary patent searches are outlined at the conclusion of …


Mass Produced: Using Local Historical Patents And Trademarks As Outreach Tools, Brendan Kelly, Rebecca Reznik-Zellen, Lisa Di Valentino Jun 2026

Mass Produced: Using Local Historical Patents And Trademarks As Outreach Tools, Brendan Kelly, Rebecca Reznik-Zellen, Lisa Di Valentino

Journal of the Patent and Trademark Resource Center Association

Historical patents and trademarks are an effective way to showcase the industries critical to the development of a region. The UMass Patent and Trademark Resource Center, based out of the Science and Engineering Library of the University of Massachusetts Amherst, created an exhibit focusing on four different industries integral to the development of Western Mass, and the patents and trademarks associated with them. We hosted an opening reception attended by campus members interested in innovation and entrepreneurship, as well as community patrons interested in the industrial history of the region. As many regions around the United States have their own …


Strategic Intent And International Corporate Entrepreneurship: The Role Of Learning Climate And Entrepreneurial Leadership In A Developing Economy, Maytha Al Ali, Muhammad Usman, Ilknur Ozturk Jun 2026

Strategic Intent And International Corporate Entrepreneurship: The Role Of Learning Climate And Entrepreneurial Leadership In A Developing Economy, Maytha Al Ali, Muhammad Usman, Ilknur Ozturk

All Works

In today's fast-paced global economy, born-global SMEs must rapidly develop strategic capabilities to compete on the international stage. Understanding how these firms cultivate entrepreneurial behavior across borders is critical for sustaining competitive advantage. However, limited research has systematically examined the mechanisms and boundary conditions through which strategic intent translates into international entrepreneurial outcomes, particularly in developing economy contexts such as Pakistan. Drawing on dynamic capabilities theory, this study explores how the strategic intent of born-global firms drives international corporate entrepreneurship (ICE). We propose that a supportive learning climate acts as a key mechanism through which strategic intent translates into ICE. …


Homelessness And Business: Perception, Affect And Opportunity, Asatur Nor-Ashkarian Jun 2026

Homelessness And Business: Perception, Affect And Opportunity, Asatur Nor-Ashkarian

University Honors Theses

This thesis examines the relationship between business owners and individuals experiencing homelessness within urban commercial districts in the United States, arguing that the dynamic is shaped primarily by spatial concentration, uneven power structures, economic pressure, and public framing rather than simple conflict between competing interests. Drawing on stakeholder analysis, business perception surveys, a mixed-methods study, and an original content analysis of 50 news articles spanning 23 states, this thesis identifies a consistent pattern: business owners broadly perceive homeless presence as negatively impacting safety, cleanliness, and consumer behavior. Local news media reinforces those perceptions through predominantly negative framing of homeless individuals. …

News Media Coverage Of Measure Ula: How The Story Of La’S Big Project To Address Homelessness And Affordable Housing Got Sidetracked By The Story Of Big Real Estate, Christopher R. Martin

Faculty Publications

“Measure ULA,” named after United to House LA, was approved by voters in Los Angeles in 2022 to create a dedicated, long-term funding source for solutions to homelessness in LA, including funding the construction of affordable homes and preventing homelessness by helping tenants stay in their homes. The funding would come from a new tax on the most expensive real estate transactions in L.A. (i.e., mansion tax), and would affect fewer than 4% of all property transactions. At the end of three years of local news coverage about Measure ULA from the Los Angeles Times and LAist, the news audience …

Mda Insurance: Why You Need A Financial Safety Net — Just In Case, Craig Start Jun 2026

Mda Insurance: Why You Need A Financial Safety Net — Just In Case, Craig Start

The Journal of the Michigan Dental Association

Craig Start, President of MDA Insurance, emphasizes the critical need for dental professionals to have a comprehensive plan for career-ending injuries or illnesses. He outlines a necessary financial safety net that includes life insurance for heirs, disability income insurance to maintain personal lifestyle, and business overhead expense insurance to protect practice value. The article provides data showing many individuals are underinsured and urges dentists to obtain professional reviews of their insurance portfolios to protect against unpredictable risks.


Staff Matters: How Much Time Off Should I Give For Bereavement?, Jodi Schafer Sphr, Shrm-Scp Jun 2026

Staff Matters: How Much Time Off Should I Give For Bereavement?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

Author Jodi Schafer provides guidance for dental practices on developing clear and consistent bereavement leave policies. She notes that while no federal law requires bereavement leave, standard employer practice typically offers three to five days for immediate family members. The article emphasizes balancing compassion for grieving employees with the operational needs of the practice. Key considerations include whether leave is paid, the definition of covered relationships, and the importance of flexibility, as grief often extends beyond a formal leave period.


Option Market Value-Based Reaction And Anticipation Of Corporate-Related Decisions By The United States Supreme Court., Yehuda Davis, Suresh Govindaraj, Yi Liu, Kate Suslava Jun 2026

Option Market Value-Based Reaction And Anticipation Of Corporate-Related Decisions By The United States Supreme Court., Yehuda Davis, Suresh Govindaraj, Yi Liu, Kate Suslava

Faculty Journal Articles

Our paper studies the option market reactions to judicial decisions in the United States Supreme Court (SCOTUS) relating to cases where at least one party involved is a public firm. Prior research finds the stock market is unable to anticipate SCOTUS's actions and registers a significant negative stock market reaction to the grant of certiorari (acceptance of a petition to review a lower court's decision) for respondents and, surprisingly, for petitioners as well. We show the negative price reaction for both petitioner and respondent firms is a consequence of increased uncertainty. We also provide evidence that on the day certiorari …

From Framework To Practice: Insights About Aligning Foundation Impact And Strategic Positioning In A Trust-Based Philanthropy Era, Nancy Pole, Marie-Andrée Mbengue-Reiver, Anne Loranger-King Jun 2026

From Framework To Practice: Insights About Aligning Foundation Impact And Strategic Positioning In A Trust-Based Philanthropy Era, Nancy Pole, Marie-Andrée Mbengue-Reiver, Anne Loranger-King

The Foundation Review

This article examines how a framework revealing foundations’ distinct orientations towards social impact has been used in practice, illustrating the tool’s utility and areas for refinement through one foundation’s experience.

Originally developed for Quebec’s philanthropic ecosystem, the heuristic positions foundations along two continua: strategic posture (problem-solving versus communitysupporting) and impact focus (grantee outcomes versus foundation outcomes), creating four impact orientation quadrants.

The case reveals productive tensions when different parts of a foundation occupy different quadrants. They are particularly acute for public foundations accountable simultaneously to donors, grantees, government funders, and communities.

These insights inform future framework iterations with a view …


Paying For Participation: Equitable Compensation Models For Community Co-Researchers, Jamie Zimmerman, Prabhneet Girn Jun 2026

Paying For Participation: Equitable Compensation Models For Community Co-Researchers, Jamie Zimmerman, Prabhneet Girn

The Foundation Review

Community-engaged research is increasingly central to philanthropic practice, yet funders rarely provide guidance for compensating community members who participate as co-researchers. This gap is especially pronounced for youth, who often face administrative, legal, and developmental constraints that complicate what “fair pay” looks like in practice.

This article presents findings from a mixed-methods comparative case study of three youth participatory action-research projects involving 44 youth ages 16–24 across varied organizational settings. Data were collected through youth surveys, focus groups, staff interviews, financial analysis, and document review.

Findings show that each model carries distinct trade-offs related to feasibility, transparency, and administrative capacity, …


How, For Whom, And Under What Conditions: Using A Causal Pathways Approach To Support The Goals Of Philanthropic Evaluation, Drew Koleros, Sophie Bright, Dana Harrison, Megan Shoji, Tina Fletcher Jun 2026

How, For Whom, And Under What Conditions: Using A Causal Pathways Approach To Support The Goals Of Philanthropic Evaluation, Drew Koleros, Sophie Bright, Dana Harrison, Megan Shoji, Tina Fletcher

The Foundation Review

Causal pathways approaches are gaining traction as evaluators seek methods that move beyond descriptive analysis to rigorously explain how, for whom, and under what conditions change occurs in complex systems. Yet there remains limited practical guidance on how to operationalize these approaches in real-world philanthropic contexts or assess their quality.

This article addresses these gaps through a case study of an evaluation taking a causal pathways approach that examines students’ experiences in four virtual and hybrid K–12 learning models. Using a realist evaluation design within a broader causal pathways orientation, the authors collaboratively developed theories of change, iteratively tested and …

Conference Calls And Information Spillover: The Role Of Analyst Participation, Amanda Awyong, Young Jun Cho, Holly I. Yang Jun 2026

Conference Calls And Information Spillover: The Role Of Analyst Participation, Amanda Awyong, Young Jun Cho, Holly I. Yang

Research Collection School Of Accountancy

We examine the role of conference calls in creating information spillover within firms. We find that analyst participation in conference calls is positively associated with subsequent revisions in management forecasts, consistent with analysts' questions prompting managers to collect additional information. We find that this effect strengthens when analysts pose more questions on new topics and when they ask questions with abnormally positive or negative tones. We also find that analyst participation has greater effects when analysts have more experience and higher forecasting ability. Further analyses demonstrate that analyst participation is associated with higher accuracy in subsequently revised forecasts. Overall, our …


Beyond The Shelf: How Reallocating Shelf Space To Emerging Brands Enhances Store Performance Through Dynamic Brand-Level Effects, Jesse Core, Ho Kim Jun 2026

Beyond The Shelf: How Reallocating Shelf Space To Emerging Brands Enhances Store Performance Through Dynamic Brand-Level Effects, Jesse Core, Ho Kim

Journal of Applied Marketing Theory

This study examines the effects of reallocating shelf space from established to emerging brands in the flavored malt beverage category, a fast-moving, impulse-driven product category. Using a 13-week field experiment in 16 U.S. grocery stores (six treated, ten control), we reallocated one shelf facing from an established to an emerging brand for four weeks before reverting the shelves to their original configuration. Then we analyzed weekly SKU-level data on sales with fixed-effects panel regressions. Results show that the shelf-space reallocation increased category sales by 21.2% during treatment and 27.6% after reversion, revealing persistent gains. At the brand level, emerging brands …


Marketing As Practice: Resolving The Hunt-Anderson Stalemate Through Practice Theory, Stephen A. Lemay, Martin Svendsen Jun 2026

Marketing As Practice: Resolving The Hunt-Anderson Stalemate Through Practice Theory, Stephen A. Lemay, Martin Svendsen

Journal of Applied Marketing Theory

This paper revisits methodological debates in marketing theory, tracing the progression from Sidney Levy’s work on symbolic consumption to the Hunt–Anderson empiricist–relativist debate. We argue that this debate rests on a category error: marketing has been misclassified as either a science or an interpretive discipline. Drawing on contemporary practice theory, we reconceptualize marketing as a professional practice oriented toward creating and managing exchange relationships within cultural contexts. This perspective resolves the Hunt–Anderson stalemate, clarifies the epistemological foundations of Consumer Culture Theory (CCT) and Transformative Consumer Research (TCR), and generates distinct research questions and methods. Through comparative exemplars, we show how …

“I” Or “We” In Times Of Crises: Should Marketers Use Individualist Or Collectivist Language When Times Are Tough?, Milad Hour, Golshad Parsimoghadam, Ali Jamei

Journal of Applied Marketing Theory

During the pandemic, as people dealt with fatalities, lockdowns, and the psychological impact of reduced social interactions, some marketing messages still captured significant public attention. What was the key element contributing to the success of these communications during such challenging times? This study focuses on the role of collectivism as a stress-coping mechanism included within marketing communications. Analyzing approximately 56,000 brand-generated posts on Platform X, the research examines how the use of collectivist language (e.g., we, us, etc.) relates to message likability, particularly as the pandemic nears its peak. The findings reveal that collectivist terms are positively associated with the …


Essays On Behavioral Aspects Of Retail Operations, Ceren Gultekin Jun 2026

Essays On Behavioral Aspects Of Retail Operations, Ceren Gultekin

Dissertations, Theses, and Capstone Projects

This dissertation combines a structured literature review on availability signaling in retail with two analytical chapters on inventory disclosure. The literature review incorporates the design and key insights of a systematic review and identifies directions for future research. Inventory disclosure is a form of availability signaling through which retailers strategically communicate stock levels to influence consumer buy-now-or-wait decisions. To mitigate strategic purchase deferrals, retailers may share low stock to create urgency or mask high stock to prevent consumers from relying on abundance. Despite its importance for profitability, academic findings and industry practices vary widely, ranging from consistent sharing to consistent …

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

Research Collection Lee Kong Chian School Of Business

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 …

We empirically examine how trust asymmetry between countries can impact the cross-border merger outcome. Differing trust perceptions between acquirer and target countries can increase the complexities of deal negotiations and integration, constraining the successful deal completion and outcome. We find, in a comprehensive global sample of 56 countries spanning 37 years, that higher trust asymmetries between the acquirer and target countries significantly increases the cross-border merger withdrawal intensity and reduces the expected synergy gains. Moreover, the adverse effects of trust asymmetry are significantly attenuated by the quality of institutions in both countries. Our results hold after employing various empirical techniques …

This study applies machine learning models such as TabNet, XGBoost, CatBoost, Support Vector Machines, a Multilayer Perceptron, and Logistic Regression to predict takeover-rumor accuracy using a proprietary dataset of 2074 rumor articles with identifiable target firms, screened from over 30,000 news articles from January 2002 to December 2011. In the raw feature (no-PCA) specification, Logistic Regression and TabNet perform similarly. After addressing class imbalance and applying dimensionality reduction (PCA), TabNet materially outperforms Logistic Regression and delivers economically meaningful gains: A TabNet-based long-short strategy earns higher average monthly abnormal returns than a Logistic Regression strategy at both horizons, 1.148% versus 0.773% …
