Digital Ecosystems And Data Regulation, Andrew Rhodes, Jidong Zhou, Junjie Zhou

Cowles Foundation Discussion Papers

This paper develops a framework in which a multiproduct ecosystem competes with multiple single-product firms in both price and innovation. The ecosystem can use data from one product to improve the quality of its other products. We use the framework to study three regulatory policies aimed at leveling the playing field. Restricting the ecosystem’s cross-product data usage, or forcing it to share data with single-product firms, benefits those firms and induces them to innovate more. However, these policies also dampen the ecosystem’s incentive to collect data and innovate, potentially raising prices. Consumers are better off only when single-product firms are …

Initial-Condition-Robust Inference In Autoregressive Models, Donald W. K. Andrews, Ming Li, Yapeng Zheng

Cowles Foundation Discussion Papers

This paper considers confidence intervals (CIs) for the autoregressive (AR) parameter in an AR model with an AR parameter that may be close or equal to one. Existing CIs rely on the assumption of a stationary or fixed initial condition to obtain correct asymptotic coverage and good finite sample coverage. When this assumption fails, their coverage can be quite poor. In this paper, we introduce a new CI for the AR parameter whose coverage probability is completely robust to the initial condition, both asymptotically and in finite samples. This CI pays only a small price in terms of its length …

Willingness To Travel With Endogenous Distance: Evidence From The Changing Retail Landscape, Yue Cao, Judith Chevalier, Jessie Handbury, Hayden Parsley, Kevin Williams

Cowles Foundation Discussion Papers

Economists often use variation in consumers’ distance from services as a source of demand variation. This approach typically treats consumer-supplier distance as exogenous, despite suppliers strategically choosing locations. We develop a novel class of instruments to address this endogeneity. These instruments exploit the spatial distribution of consumer demographics and can be constructed from standard cross-sectional data, making them useful in a variety of spatial applications. Our preferred instruments use the income composition of concentric discs centered on the Central Business District. Applying these instruments to smartphone geolocation data for millions of devices across 18 metropolitan areas, we estimate consumer preferences …

Border Perceptions: Security And Immigration In The South Texas Borderlands, Carla Angulo-Pasel, Mi-Son Kim, Adrien A. Halliez

School of Political Science, Public Affairs, Legal and Security Studies Faculty Publications

With the Trump administration, we witnessed a hardening of border security policy and practices. Trump used his leadership and celebrity to explicitly attack and criminalize “undocumented” migrants with a discourse of threat, danger, invasion, crisis. Policywise, he took steps to further securitize the borderlands. In this paper, we examine how public opinion has differed with regards to the support or opposition to these hard security policies, especially in borderland areas when compared to the overall national population. The aim of this paper is to examine this difference by directing our attention to the Rio Grande Valley (RGV), a borderlands region …

Marx And Engels On Prisons And Capitalism, James Parisot

Sociology Faculty Publications

This paper rethinks Marx and Engels’ comments on imprisonment and capitalism. While there has been a tendency to suggest the authors’ comments on crime and punishment were peripheral and secondary to their major projects, such as Marx’s Capital, this paper claims, in fact, their writings on incarceration were guided by their shared theoretical project which included historicizing systems of punishment as correlating with modes of production. Also, while more has been written on their ideas of criminality, instead, this paper excavates their thoughts on prisons, which have often been neglected. Overall, it shows there has been a tendency to …

How Do Social Isolation And Loneliness Vary By Age?, Jihye Baek, Cal J. Halvorsen

Harvey A. Friedman Center for Aging

Social isolation and loneliness, which are experienced by many older adults, can negatively impact health and well-being. Although often used interchangeably, social isolation is defined as an objective lack of social ties (e.g., number of close family members or friends) and loneliness as an internal sense of disconnection (e.g., feeling alone even when surrounded by others). Because social relationships, health, and life circumstances change as we age, patterns of social isolation and loneliness may differ by age group. Therefore, this research brief asks, How do patterns of social isolation and loneliness differ across age groups among community-dwelling older adults? 

Derivation Of An Updated Brief Multivariable Prediction Model To Detect Panic-Related Anxiety In Emergency Department Patients With Cardiopulmonary Complaints, Sharon C. Sung, Felicia J. L. Ang, Arul Earnest, Leslie E. C. Lim, Shreshtha Jolly, Gilaine Rui Ng, A. John Rush, Marcus E. H. Ong

Research Collection School of Social Sciences

Background Patients with panic related-anxiety (i.e., panic attacks or panic disorder) frequently present to emergency departments (EDs) with cardiopulmonary complaints but are often undiagnosed, which can lead to recurrent visits and prolonged distress. This study aimed to derive a new symptom-based multivariable diagnostic prediction model to detect panic-related anxiety in ED patients with cardiopulmonary symptoms.Methods We conducted a single-blind prospective derivation study over 15 months in the ED of a major tertiary hospital in Singapore. Patients presenting with symptoms of palpitations, chest pain, dizziness, or difficulty breathing were assessed using the Structured Clinical Interview for DSM Disorders (SCID) to diagnose …

Essays On Public Policy And Health Outcomes: Unintended Consequences And The Cost Of Influence, Wenhan Yan

Dissertations and Theses Collection (Open Access)

This dissertation investigates the complex behavioral responses to public policy shifts and institutional cues, quantifying their intended and unintended societal impacts. Across two distinct empirical contexts, this research examines how individuals adapt their risk profiles when signals from political or legal authorities change and how these adaptations generate measurable externalities.

The first chapter, "From Punishment to Treatment: Unintended Social Impacts of Changing Drug Policies," shifts the focus to the intersection of health policy and criminal justice. This chapter evaluates the sudden transition from punitive drug enforcement to health-oriented decriminalization, utilizing the 2021 State v. Blake decision in Washington as a …

The Impacts Of Political Leaders’ Social Capital On Policy Success: The Case Of Local Food Systems, In Hae Noh, Beomgeun Cho, April M. Roggio, Luis F. Luna-Reyes

Research Collection School of Social Sciences

Network approaches to collaborative leadership suggest that local leaders’ success depends on activities that connect their organization to diverse stakeholders and resources. Drawing on the literature on managerial networking and a mixed-methods approach that includes 38 semi-structured interviews and a survey of 185 New York State municipal leaders, we explore the impact of leaders’ networking efforts on food access and security in their communities. We hypothesize that different forms of leaders’ social capital (bridging, bonding, and linking) has an impact on policy success. Our results suggest that only bridging social capital has an impact on food access. We conclude with …

Examining The Effects Of Viewing Nature And Animal Smartphone Wallpapers On Affect, Behaviour, And Cognition: A Randomised Cross-Over Trial, Nadyanna M. Majeed, Nicole R. Y. Chen, Adalia Y. H. Goh, Meilan Hu, Kenneth J. J. Koh, Yuolmae H. G. Ang, Andree Hartanto

Research Collection School of Social Sciences

This study aims to investigate the effects of different smartphone lock screen wallpapers on weekly perceived well-being, procrastination, and productivity in young adults. Through a pre-registered within-subject experiment, 60 participants were exposed to three smartphone wallpaper conditions: nature, animal, and neutral (control). Each participant experienced each condition over three weeks, with the order of conditions counterbalanced. Using Frequentist and Bayesian analyses, we did not find any differences between conditions across the pre-registered confirmatory outcomes (i.e., life satisfaction, positive affect, negative affect, stress, productivity, and procrastination). Exploratory outcomes related to lock screen engagement, however, revealed some meaningful effects. Animal-themed smartphone wallpapers …

Navigating Climate Change In Carbon Negative Bhutan: Insights From Policy Influencers And Comparison To The Wider Himalayan Region, Tashi Dorji, Angus Morrison-Saunders, David Blake

Research outputs 2022 to 2026

Climate change is one of the most pressing global challenges and spares no nation. Bhutan, as the only carbon negative country in the world, is no exception and being in the Himalayas – a region warming faster than the global average – further intensifies climate risks. This study explores how Bhutan navigates climate change through the perspectives of 41 policy influencers, including politicians, civil servants, and leaders from nongovernment organisations and the media. The findings are compared with scientific literature from the broader Himalayan region to identify shared vulnerabilities (e.g., glacial lake outburst floods, water scarcity, and agricultural disruptions) and …

Beyond Resilience: The Case For Regenerative, Restorative Cities, Lily Kong

Research Collection School of Social Sciences

In a commentary, SMU President Professor Lily Kong mentioned that at the City Dialogues event, co-convened by SMU and Urban Innovation Vienna, participants agreed that cities must equip their residents to withstand shocks and thrive in an evolving urban environment. Prof Kong said resilient cities anticipate, adapt and respond effectively to disruptions, which involves attention not only to physical infrastructure, but also to social cohesion and institutional foresight. She said that embedding sustainability into urban design is fundamental to ensuring cities flourish in a world of climate uncertainty and resource constraints. She added that the value of urban resilience lies …

Counter-Urbanization In China: A Systematic Review Toward A Comprehensive Typology, Chengxue Yang, Qian Forrest Zhang

Research Collection School of Social Sciences

Drawing on a systematic review of both international and Chinese-language scholarship on counter-urbanization in China, this article proposes a comprehensive typology of counter-urbanization migrations—consisting of eight types of new migrants—based on the diverse motivations driving such migration. We build a bilingual corpus of 273 research papers published between the 1970s and 2025. Integrating bibliometric mapping and qualitative synthesis, we conduct a systematic review to trace the temporal evolution and thematic diversification of counter-urbanization research. The review reveals persistent conceptual ambiguity surrounding counter-urbanization in the Chinese context, which this study addresses by conceptually distinguishing counter-urbanization from suburban expansion, population decentralization, and …

Asia’S Future Will Be Won By Soft Power, Not Force, Lily Kong

Research Collection School of Social Sciences

Lily Kong argues that while force remains essential to deter aggression and manage worst-case scenarios, military strength may prevent defeat, but it rarely produces legitimacy. When hard power dominates the strategic imagination, volatility rises and markets suffer. Soft power – the ability to influence countries through persuasion, attraction and legitimacy – has become a strategic asset, she writes. It shapes expectations, lowers baseline tensions, and creates off-ramps in moments of crisis, often determining whether tensions escalate, how long crises last, and how much economic damage they inflict. Prof Kong believes that in a nuclear-armed, economically interdependent Asia, the real test …

Dual Self-Construal Integration (Dsci) And Romantic Relationships In Singapore: Enhancing Romantic Relationship Satisfaction Through Creativity, Kenneth Tan, Chi-Ying Cheng, Gloria J. Lai, Daniel Ho

Research Collection School of Social Sciences

Research has shown that independent vs. interdependent self-construals are largely shaped by culture and can predict the endorsement of distinct relational schemes when dealing with close others. Intriguingly, individuals exposed to both Eastern and Western cultures can develop both independent and interdependent self-construals and possess the two seemingly conflicting self-construals simultaneously. What is less explored is how different management of both independent and interdependent self-construals influence individuals' navigation of relational schemas in their romantic relationships. The current research examines the influence of how one's dual self-construal integration (DSCI)—an individual difference measure that captures the degree to which individuals perceive independent …

Projecting Inflation Tail Risks In A Small Open Economy: Some Evidence From Singapore, Hwee Kwan Chow-Tan, Jordan Lee

Research Collection School Of Economics

This study empirically assesses the drivers of risks to the inflation outlook for a small open economy like Singapore. We apply the inflation-at-risk framework of López-Salido and Loria (2020) and incorporate projections from the Survey of Professional Forecasters (SPF) as point forecasts of inflation. Our findings show that macro-financial risk factors—shaped by Singapore’s openness, role as a financial hub, and exchange rate–centered monetary policy framework—enter nonlinearly into inflation risk models and exert differentiated effects. Foreign price pressures heighten upside risks, and exchange rate policy has proven effective at mitigating them. Tighter global financial conditions amplify inflation risks through cost-push channels, …

New Asymptotics Applied To Functional Coefficient Regression And Climate Sensitivity Analysis, Qiying Wang, Peter C. B. Phillips, Ying Wang

Research Collection School Of Economics

A general asymptotic theory is established for sample cross moments of nonstationary time series, allowing for long-range dependence and local unit roots. The theory provides a substantial extension of earlier results on nonparametric regression that include near-cointegrated nonparametric regression as well as spurious nonparametric regression. Many new models are covered by the limit theory, among which are functional coefficient regressions in which both regressors and the functional covariate are nonstationary. Simulations show finite sample performance matching well with the asymptotic theory and having broad relevance to applications, while revealing how dual nonstationarity in regressors and covariates raises sensitivity to bandwidth …

Existence Of Equilibrium Mechanisms In Generalized Principal-Agent Problems With Interacting Teams, Brian Roberson

ESI Working Papers

We study incentive design when multiple principals simultaneously design mechanisms for their respective teams in environments with strategic spillovers. In this environment, each principal’s set of incentive-compatible mechanisms—those that satisfy their own agents’ incentive compatibility constraints— depends on the mechanisms offered by the other teams. Following a classic example by Myerson (1982), such games may lack equilibrium due to discontinuities in the correspondence of incentive-compatible mechanisms. We establish general conditions for equilibrium existence by introducing a novel approach that involves tracking both the outcome distributions along the truthful-obedient path and the sets of outcome distributions achievable through unilateral deviations, thereby …

Son Finds Long-Lost Photo Of His Father Beside Amelia Earhart, Thanks To Gsu Library’S Special Collections, Roy Cummings

Georgia Library Quarterly

While exploring the Digital Library of Georgia, Daniel Brown discovered a long-lost photograph of his father standing beside Amelia Earhart at Atlanta’s Candler Field in 1934. The image confirmed a story his father told for decades but never had proof of. The rediscovery highlights how digitized archival collections preserve history while unexpectedly reconnecting families with their own past.

Uncertain Search With Knowledge Transfer, Woonghee Tim Huh, Michael Jong Kim, Meichun Lin

Research Collection Lee Kong Chian School Of Business

We consider a sequential search over a group of similar alternatives. The individual value of an alternative contains two components, an observable utility and an idiosyncratic value. Observable utilities share an unknown population distribution, which captures the similarity across the alternatives and allows for knowledge transfer within the group. Once a decision maker encounters an alternative, its utility is revealed immediately, whereas the idiosyncratic value is unobservable and needs to be learned by sampling. The goal is to select an alternative with the highest individual value while accounting for the sampling and search costs. A novel feature of this problem …
