Decoding Gpt Mania In Chinese Stock Market, Yan Ma, Nan Hu, Shuyang Jia

Research Collection School Of Computing and Information Systems

This study investigates the impact of investor attention on stock market reactions to ChatGPT using dialogues on the Chinese interactive investor platforms (IIPs). We measure investor attention by the number of investors’ questions toward ChatGPT on the IIPs and categorize the firms’ answers as Investing, Speculative, and Absent. The research reveals positive and statistically significant market reactions surrounding the initial questions that occur before firm responses. Positive abnormal returns are also observed around the initial answer dates, with Investing firms evoking the highest market response, followed by Speculative firms, and Absent firms exhibiting the lowest reactions. Our results suggest that …

Digitally Connected, Evolutionarily Wired: An Evolutionary Mismatch Perspective On Digital Work, Mark Van Vugt, Stephen M. Colarelli, Norman P. Li

Research Collection School of Social Sciences

This paper makes the case for an evolutionary mismatch between digital work and the way human ancestors engaged in work. Psychological adaptations for producing things that early humans needed to survive and thrive, such as cognitive mechanisms for obtaining and processing food, toolmaking, and learning valuable working skills, evolved in the context of small networks of hunter–gatherers. These adaptations are central to understanding the significance of work in human evolution. Evolutionary mismatches operate when novel environments cue ancestral adaptations in ways that no longer provide adaptive benefits. We argue that digital work, although efficient and productive, is misaligned with some …

Post-Productivism And Rural Revitalization In China: Drivers And Outcomes, Meiling Wu, Qian Forrest Zhang, John A. Donaldson

Research Collection School of Social Sciences

We propose that post-productivism offers a useful analytical framework for understanding the multi-scalar and diverse changes that are taking place in China’s rural revitalization. As a theoretical framework that emerged from the study of rural changes in the Global North, the applicability of post-productivism in the Global South has been contested. This paper offers the first comprehensive analysis of the emergence of post-productivism in rural China and uses post-productivism as a framework to conceptualize a wide range of changes in China’s rural revitalization. We conceptually clarify the driving forces that give rise to post-productivism and the outcomes these drivers produce. …

The Interaction Effects Of Fintech And Bank Lending On Growth: Evidence From The Asean Region, Tan Swee Liang

Research Collection School Of Economics

This study examined the interaction effects of traditional bank lending and emerging fintech credit on economic growth in six ASEAN economies from 2013 to 2020. Using a two-way fixed effects (FE) model and the panel-corrected standard error (PCSE) method, the study found a statistically significant and positive interaction effect between bank lending and fintech credit. Specifically, fintech credit became increasingly important in shaping economic growth as bank lending ratios exceeded a certain threshold. Countries with high bank lending ratios experienced greater GDP per capita growth when accompanied by greater fintech credit. These findings suggest that policies supporting fintech development alongside …

How Can Cbdcs Be Designed To Drive Financial Inclusion?, Heng Wang

Research Collection Yong Pung How School Of Law

As a new form of national currency, central bank digital currencies (CBDCs) hold the potential to be a transformative innovation that can enhance financial inclusion. However, the realization of this potential is very much contingent on their design. The realization of the benefit is also influenced by the barriers to financial inclusion that were identified in our first blog such as financial literacy, digital divide, and complexity.

Reachability-Aware Fair Influence Maximization, Wenyue Ma, Maximilian K. Egger, Andreas Pavlogiannis, Yuchen Li, Panagiotis Karras

Research Collection School Of Computing and Information Systems

How can we ensure that an information dissemination campaign reaches every corner of society and also achieves high overall reach? The problem of maximizing the spread of influence over a social network has commonly been considered with an aggregate objective. Less attention has been paid to achieving equality of opportunity, reducing information barriers, and ensuring that everyone in the network has a fair chance to be reached. To that end, the fairness objective aims to maximize the minimum probability of reaching an individual. To address this inapproximable problem, past research has proposed heuristics, which, however, perform less well when the …

Ten Years As Boundary Object: The Search For Identity And Belonging As 'Hongkongers', John Lowe, Darlene Machell Espena, George Wong

Research Collection College of Integrative Studies

This article examines the complex process of symbolic boundary-making of ‘Hongkonger’ cultural identities through the lens of the controversial 2015 film Ten Years, which is a celebrated omnibus production comprised of five short segments that picture a dystopic end to Hong Kong’s cherished way of life in the year 2025. The article is premised on an interdisciplinary approach engaging with cultural studies and film studies. On one hand, it explores how Ten Years functioned as a boundary object, a vast terrain within which cultural identities of what it means to be a Hongkonger are constructed, banished, imagined, and performed under …

Integration Of Urban Climate Research Within The Global Climate Change Discourse, Negin Nazarian, Benjamin Bechtel, Gerald Mills, Melissa Anne Hart, Ariane Middel, E. Scott Krayenhoff, Gaby S. Langendijk, Lei Zhao, Andy Pitman, Winston T. L. Chow

Research Collection College of Integrative Studies

Global climate science needs to address a fundamental challenge: the mismatch between the scales of anthropogenic processes driving change and the resulting climate impacts. While projected climate changes and impacts are global in extent, the drivers of this change, and the exposure to its impacts, are concentrated in densely populated urban areas. Despite occupying only 1–3% of the land, urban areas are home to most of the world’s population and responsible for ~70% of current greenhouse gas emissions [1]. By 2050, an additional 2.5 billion people are expected to live in urban areas, with up to 90% of this growth …

Retirement And Life Satisfaction Among Middle-Aged And Older Adults: A Piecewise Growth Mixture Analysis, Jonathan L. Chia, Andree Hartanto, William Tov

Research Collection School of Social Sciences

Retirement represents a significant life transition typically occurring in later adulthood, often accompanied by substantial lifestyle changes. Several theoretical frameworks suggest that these changes present both opportunities and challenges for well-being, and the extent to which individuals experience positive versus negative well-being outcomes may be influenced by various factors. To study such heterogeneity in retirement experiences, researchers have embraced person-centered methodologies. Yet, some previous studies have not robustly delineated retirement- from age-related changes in well-being, accounted for statistical uncertainties, or examined these diverse experiences outside of a Western context. These limitations preclude conclusions about the diverse experience of retirement. Using …

Falsehoods, Foreign Interference, And Compelled Speech In Singapore, Kenny Chng

Research Collection Yong Pung How School Of Law

Online misinformation endangers the infrastructure of fact essential to public discourse and presents an even greater threat where it is being utilised as a weapon by hostile state actors. In recognition of these dangers, Singapore has implemented legal measures to combat online misinformation, enacting in quick succession the Protection from Online Falsehoods and Manipulation Act (POFMA) and the Foreign Interference (Countermeasures) Act (FICA). These statutes open up novel frontiers of development for Singapore's free speech jurisprudence. Indeed, these statutes confer upon government authorities the power to compel the authors of certain material to display notices stating that the material contains …

How Can Malaysian Courts Consistently Perform Meaningful Constitutional Rights Review? Lessons From Past Cases And The Way Forward, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

In the past, Malaysian courts performing constitutional rights review played a merely clerical role, applying a test that was trivially easy for legislation to pass. Then a more rigorous proportionality test took root. However, the Federal Court in the 2020 case of Letitia Bosman whittled the test down again, and the courts once more played a minimal role in checking state action. The reasons for this cannot be explained merely by diversity in judicial philosophy or political contextual factors. Rather, the near-demise of proportionality (and, with it, robust constitutional review) was made possible by a lack of a clear sense …

My Manager Endorsed My Coworkers’ Voice: Understanding Observers’ Positive And Negative Reactions To Managerial Endorsement Of Coworker Voice., Emily Poulton, Szu-Han Joanna Lin, Shereen Fatimah, Cony Ho, Lance Ferris, Russell Johnson

Research Collection Lee Kong Chian School Of Business

Research on managerial voice endorsement has primarily focused on the processes and conditions through which voicers receive their managers’ endorsement. We shift this focus away from the voicers, focusing instead on the dual reactions that endorsement generates for observing employees. Drawing from an approach-avoidance framework, we propose that managerial endorsement of coworker voice could be perceived as a positive and negative stimulus for observers, prompting them to approach opportunities and avoid threats, respectively. Results from a pre-registered experiment and a multi-wave, multi-source field study revealed that managerial endorsement of coworker voice was positively related to observers’ voice instrumentality, thus prompting …

Geographic Links And Predictable Returns, Zuben Jin, Frank Weikai Li

Research Collection Lee Kong Chian School Of Business

Using establishment-level data of U.S. public firms, we construct a novel measure of geographic linkage between firms. We show that the returns of geography-linked firms have strong predictive power for focal firm returns and fundamentals. This effect is distinct from other cross-firm return predictability and is not easily attributable to risk-based explanations. It is more pronounced for focal firms that receive lower investor attention, are more costly to arbitrage, and during high sentiment periods. The cross-firm information spillovers and return predictability are also stronger for geographic peers with economic linkages and with positive information. Our results are broadly consistent with …

The Partnership Question As A Scale Question: Extending The Theorization Of Entrepreneurial Urbanism In China, Yong Zhang

Research Collection College of Integrative Studies

In this article I examine recent theoretical and empirical exchanges around partnership-based urban governance between North Atlantic and Chinese academics and policymakers. I argue that the latest wave of de jure private–public partnerships in urban China reflects an ongoing process of governance rescaling beyond conventional entrepreneurial urbanism theory. I propose an analytical framework that foregrounds successive experimental partnerships as tensions between institutional continuity and change arising from rescaling. In this study I examine variegated actually existing partnerships in Jiyuan, China, to identify generalizable ideal types of partnership-driven governance rescaling. I conclude by suggesting to enhance the theorization of entrepreneurial urbanism …

Anopas: Practical Anonymous Transit Pass From Group Signatures With Time-Bound Keys, Rui Shi, Yang Yang, Yingjiu Li, Huamin Feng, Hwee Hwa Pang, Robert H. Deng

Research Collection School Of Computing and Information Systems

An anonymous transit pass system allows passengers to access transport services within fixed time periods, with their privileges automatically deactivating upon time expiration. Although existing transit pass systems are deployable on powerful devices like PCs, their adaptation to more user-friendly devices, such as mobile phones with smart cards, is inefficient due to their reliance on heavy-weight operations like bilinear maps. In this paper, we introduce an innovative anonymous transit pass system, dubbed Anopas, optimized for deployment on mobile phones with smart cards, where the smart card is responsible for crucial lightweight operations and the mobile phone handles key-independent and time-consuming …

Path-Choice-Constrained Bus Bridging Design Under Urban Rail Transit Disruptions, Yiyang Zhu, Jian Gang Jin, Hai Wang

Research Collection School Of Computing and Information Systems

Although urban rail transit systems play a crucial role in urban mobility, they frequently suffer from unexpected disruptions due to power loss, severe weather, equipment failure, and other factors that cause significant disruptions in passenger travel and, in turn, socioeconomic losses. To alleviate the inconvenience of affected passengers, bus bridging services are often provided when rail service has been suspended. Prior research has yielded various methodologies for effective bus bridging services; however, they are mainly based on the strong assumption that passengers must follow predetermined bus bridging routes. Less attention is paid to passengers’ path choice behaviors, which could affect …

Optimization Of Customer Service And Driver Dispatch Areas For On-Demand Food Delivery, Jingfeng Yang, Hoong Chuin Lau, Hai Wang

Research Collection School Of Computing and Information Systems

With the rapid development and popularization of mobile and wireless communication technologies, on-demand food delivery (OFD) platforms have been able to connect restaurants, customers, and drivers in real time, drastically changing dining and food delivery services. Motivated by the critical need for supply and demand management in the on-demand food delivery market, we focus on the optimization of customer service area and driver dispatch area for on-demand food delivery services. Specifically, for each restaurant, the platform needs to decide the (1) customer service area (CSA), i.e., the surrounding area within which customers can see the restaurant’s information and order food …

Cross-Exchange Crypto Risk: A High-Frequency Dynamic Network Perspective, Yifu Wang, Wanbo Lu, Min-Bin Liu, Rui Ren, Wolfgang Karl Hardle

Sim Kee Boon Institute for Financial Economics

Cross-exchange crypto trading presents inherent risks, particularly for centralized exchanges. Investors observe exacerbating crypto volatility and counterparty risk and would like to quantify these elements of crypto trades. The multiple exchanges require a multivariate view on the structures of risk spillover across exchanges. Here, a Multivariate Heterogeneous AutoRegression (MHAR) model is designed and analyzed, accommodating the stylized facts of crypto markets, including 24/7 trading and the long-memory effect on return variations. The proposed MHAR approach clearly reveals the intensity of interconnectedness among exchanges during extreme events, e.g., the Bitcoin market. Additionally, one observes extremely volatile eigenvector centralities of Futures Exchange …

Transportation, Healthcare Seeking, And Outcomes, Xiao Lin Ong

Dissertations and Theses Collection (Open Access)

Advancements in engineering and transportation technology have integrated commuting into modern living. Most studies on transportation infrastructure, such as roads and railways, focus on economic outcomes. This paper examines an overlooked outcome of transportation connectivity: access to medical care. We study the role transportation networks play in determining patients’ treatment location choices. Specifically, we aim to study 1) why patients travel to begin with, 2) how do patients choose where to go for treatment, and 3) how travel times can affect patients’ travel decisions. To do so, we develop a dynamic discrete choice, spatial model and provide empirical estimates. We …

Report On Findings From Household Needs Study, Paulin T. Straughan, Mathew Mathews

ROSA Research Briefs

The Household Needs Study (HNS) aimed to capture public perspectives on essential items and activities that are deemed necessary for a normal life in Singapore and to understand the extent to which Singaporeans are able to access these items and activities. To do so, the study adopted the Living Standards Approach (Saunders, Naidoo & Wong, 2022), which purports that individuals experience relative deprivation and/or social exclusion if they do not have access to items and activities that are deemed to be essential by society. In this study, a survey was conducted with a nationally representative sample of around 4,000 respondents …
