The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …

High Frequency Factor Analysis With Partially Observable Factors, Dachuan Chen, Wenqi Lu, Siyu Xie

Research Collection School Of Economics

This paper considers a novel factor structure – Partially Observable Factor Model – where both observable factors and latent factors exist in the model simultaneously. Such factor structure can make sure both interpretability and goodness-of-fit at the same time. Necessary estimation methodologies for this partially observable factor model are developed in this paper for the high frequency data. The proposed estimation methodology is robust to jumps, microstructure noise and asynchronous observation times simultaneously.When the observable factors are exogenous, we provide the estimation theory for the integrated eigenvalues of the residual covariance matrix, which including the bias-corrected estimator, central limit theorem …

The Role Of Private Law In Promoting Building Safety: The Case Of Singapore, Edward S. W. Ti

Research Collection Yong Pung How School Of Law

Singapore is a tiny granite rock situated just north of the equator. Lacking land, and indeed any kind of natural resource, means that the trend for urban development in the city-state will always be densifi cation; 96 per cent of residents in Singapore already live in multi-owned housing, ie high-rise apartments. 1 Singapore is also a rapidly greying nation. 2 It has been observed that persons over 70 years old are four times more vulnerable in the event of a fi re, 3 and fi re safety is a critical aspect of building safety. Safety features and measures in the …

The Basic Structure In Malaysia: Less Than Meets The Eye, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

At first glance, studying the basic structure doctrine in Malaysia can be frustrating due to its inconsistent judicial treatment. While early cases such as Loh Kooi Choon and Phang Chin Hock rejected the doctrine, it was later accepted in landmark decisions like Sivarasa Rasiah, Semenyih Jaya, and Indira Gandhi. In 2020, scholars such as Jaclyn Neo and Yvonne Tew suggested a judicial embrace of the doctrine and its global trend toward constitutional unamendability. However, the Federal Court’s 2021 decision in Maria Chin Abdullah appeared to reject it once more, illustrating the doctrine’s precarious status. The resurgence seen in Dhinesh a/l …

Digital Economy Innovation In The Indo-Pacific: Towards A 'Singapore Effect'?, J.G. Allen, Qiu Xu Martin Liao

Research Collection Yong Pung How School Of Law

This paper examines the rise of Digital Economy Agreements (DEAs) in the Indo-Pacific as a strategic response to digital trade fragmentation and great power competition. Focusing on Singapore’s leadership, we introduce the ‘Singapore Effect’ – a model of regulatory influence distinct from others, such as the ‘Brussels Effect’ and ‘Beijing Effect.’ Unlike market-driven regulatory diffusion, the Singapore Effect emphasizes interoperability, norm entrepreneurship, and mini-lateralism, enabling middle powers to shape digital trade governance. We analyze DEA formation, implementation challenges in national law, and Singapore’s role as a bridge between diverse regulatory regimes. DEAs’ flexible, modular structure allows for incremental regulatory alignment …

The Crucial Role Of Insolvency Law In Job Creation And Preservation, Andrés F. Martínez, Aurelio Gurrea-Martinez, Harish Natarajan

Research Collection Yong Pung How School Of Law

When companies face financial trouble, potential job losses can be a major risk for people and—depending on the size of the company or industry in trouble—a risk to local or national economies. An efficient insolvency system can mitigate this risk while contributing to the creation of more and better jobs. As jobs are the most critical tool in fighting poverty, a better understanding of the effects of insolvency law on employment is vital for development work.

Relational History: Correcting Temporal Myopia In Social Network Research, Julia Brennecke, Gianluca Carnabuci, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

Scholars have used network concepts and methods to explain a wide range of organizational phenomena. Despite this broad interest, prevalent approaches tend to neglect a critical constitutive dimension of network ties: their history. We invoke the concept of relational history to signify the temporal path and biography of a network tie. We argue that a network tie’s history shapes what the relationship means to the parties involved, what can be accomplished in and through the relationship, and how the relationship might further evolve. In directing the attention of organizational network researchers to the relational history of network ties, we aim …

Han-Wei Liu & Weiping He Australian Banking And Finance Law And Regulation, Chin Seng Bryan Leow, Kwan Ho Lau

Research Collection Library

It is a near-Sisyphean feat to properly set out the myriad interlinking issues in banking and finance law within a jurisdiction, and this is before tackling the accompanying regulatory issues. Pushing that proverbial boulder up the hill requires a firm grounding in the applicable black-letter rules; a good sense of the regulatory theories adopted by the supervisory authorities; and, finally, a keen appreciation of potential problems presented by the constant stream of novel financial products (and technology). In their book Australian Banking and Finance Law and Regulation, Han-Wei Liu and Weiping He have examined the Australian position relating to the …

Why University Libraries Should Not Overlook Research Staff, Bella Ratmelia

Ai Assisted Literature Review Tools For Undergraduates: Restrict, Embrace Or Curate?, Aaron Tay

Research Collection Library

As AI-driven literature review tools become widespread, academic librarians must grapple with a fundamental question—should we ban these tools, selectively curate their use, or embrace them fully? This keynote explores the three competing schools of thought shaping AI’s role in undergraduate literature reviews.

The Restrict school argues that students who have not proven capable of writing quality literature review should be restricted from use of such tools. Much like handing a preschooler a calculator before they understand basic arithmetic will affect the learning of arithmetic, premature use of such tools has the potential to shortcut the research learning process. If …

Stress Reactivity And Sociocultural Learning: More Stress-Reactive Individuals Are Quicker At Learning Sociocultural Norms From Experiential Feedback, Shilpa Madan, Krishna Savani, Pranjal H. Mehta, Desiree Y. Phua, Ying-Yi Hong, Michael W. Morris

Research Collection Lee Kong Chian School Of Business

When interacting with others in unfamiliar sociocultural settings, people need to learn the norms guiding appropriate behavior. The present research investigates an individual difference that helps this kind of learning: stress reactivity. Interactions in an unfamiliar sociocultural setting are stressful, particularly when the actor fails to follow its rules. Although stress is typically considered a liability, more stress-reactive individuals may be more motivated to improve, and, thus, quicker to learn these rules. Consistent with this idea, a pilot study found that people genetically inclined to stress reactivity, as computed by a genetic profile score across 59 single nucleotide polymorphisms on …

Major Customers And Carbon Footprints Along The Supply Chain, Saiying Deng, Tinghua Duan, Frank Weikai Li, Xiaoling Pu

Research Collection Lee Kong Chian School Of Business

This paper examines whether major corporate customers curb corporate carbon emissions along the supply chain. We show that suppliers with a more concentrated customer base have significantly lower carbon emissions. The results are robust to alternative measures of carbon emissions and customer concentration, alternative sample, alternative explanation, and various approaches to mitigate endogeneity concerns. The effect is more pronounced when major customers have made emission-reduction commitment, when they are exposed to greater climate regulatory shocks and risks, and when they become more concerned about regulatory scrutiny. Moreover, the curbing effect of major customers on supplier carbon emissions is stronger when …

Infrastructural Splintering Along The Bri: Catholic Political Ecologies And The Fractious Futures Of Sri Lanka’S Littoral Spaces, Orlando Woods

Research Collection College of Integrative Studies

This article considers the ways in which the material infrastructures of China’s Belt and Road Initiative (BRI) intersect with other infrastructural formations, and how the resulting overlaps can trigger processes of what I call “infrastructural splintering”. These processes cause infrastructure to be experienced in differentiating ways, creating divisive politics where there might once have been unity. Embracing these politics as an analytical starting point undermines the techno-material stability of the BRI, and reveals its more-than-material affects. I illustrate these ideas by developing a case study of the effects of the China-backed Colombo Port City project on Catholic fishing communities that …

Emulating Empire: Washington’S Preoccupation With British Counterinsurgency In Malaya And U.S. Commitment To Vietnam, Wen-Qing Ngoei

Research Collection College of Integrative Studies

This essay examines how Washington’s deep preoccupation with the British-Malayan counterinsurgency tactics–tactics that routed the guerilla fighters of the Malayan Communist Party–shaped US commitment to Vietnam. This US preoccupation, stoked by Britain’s (and Malaya’s) promotion of their counterinsurgency knowledge to US leaders, also influenced the lessons that US analysts and thinkers absorbed from the United States’ defeat in Indochina. Most studies of British-Malayan counterinsurgency and its connection to the Vietnam War fixate upon debating the relevance of the former to the latter and how this bears on US failures in Indochina. However, this essay focuses on the understudied fervor with …

Runtime Backdoor Detection For Federated Learning Via Representational Dissimilarity Analysis, Xiyue Zhang, Xiaoyong Xue, Xiaoning Du, Xiaofei Xie, Yang Liu, Meng Sun

Research Collection School Of Computing and Information Systems

Federated learning (FL), as a powerful learning paradigm, trains a shared model by aggregating model updates from distributed clients. However, the decoupling of model learning from local data makes FL highly vulnerable to backdoor attacks, where a single compromised client can poison the shared model. While recent progress has been made in backdoor detection, existing methods face challenges with detection accuracy and runtime effectiveness, particularly when dealing with complex model architectures. In this work, we propose a novel approach to detecting malicious clients in an accurate, stable, and efficient manner. Our method utilizes a sampling-based network representation method to quantify …

Nexusgs: Sparse View Synthesis With Epipolar Depth Priors In 3d Gaussian Splatting, Yulong Zheng, Zicheng Jiang, Shengfeng He, Yandu Sun, Junyu Dong, Huaidong Zhang, Yong Du

Research Collection School Of Computing and Information Systems

Neural Radiance Field (NeRF) and 3D Gaussian Splatting (3DGS) have noticeably advanced photo-realistic novel view synthesis using images from densely spaced camera viewpoints. However, these methods struggle in few-shot scenarios due to limited supervision. In this paper, we present NexusGS, a 3DGS-based approach that enhances novel view synthesis from sparse-view images by directly embedding depth information into point clouds, without relying on complex manual regularizations. Exploiting the inherent epipolar geometry of 3DGS, our method introduces a novel point cloud densification strategy that initializes 3DGS with a dense point cloud, reducing randomness in point placement while preventing over-smoothing and overfitting. Specifically, …

A Multimodal Fusion Model Leveraging Mlp Mixer And Handcrafted Features-Based Deep Learning Networks For Facial Palsy Detection, Heng Yim Nicole Oo, Min Hun Lee, Jeong Hoon Lim

Research Collection School Of Computing and Information Systems

Algorithmic detection of facial palsy offers the potential to improve current practices, which usually involve labor-intensive and subjective assessments by clinicians. In this paper, we present a multimodal fusion-based deep learning model that utilizes an MLP mixer-based model to process unstructured data (i.e. RGB images or images with facial line segments) and a feed-forward neural network to process structured data (i.e. facial landmark coordinates, features of facial expressions, or handcrafted features) for detecting facial palsy. We then contribute to a study to analyze the effect of different data modalities and the benefits of a multimodal fusion-based approach using videos of …

Reducing Carbon Emissions Through Sustainable Food Consumption: Applying An A-S-I Framework On Beijing Residents, Xuan Yang, Jiaxin Zou, Jingyao Gao, Shu Yang

Student Publications

The food sector represents one of the largest contributors to global climate change, making it urgent for the public to transform their food consumption behavior. However, food consumption behaviors that can facilitate carbon reduction, and how to classify these behaviors from the perspective of behavioral science, have not been deeply explored. This study pioneers a novel categorization of carbon-mitigating food consumption behaviors based on an A-S-I framework (i.e., “Avoid” food loss and waste, “Shift” to low-carbon alternatives, and “Improve” dietary structure). Such a classification not only encompasses the full spectrum of emission-altering behaviors but also enables identification of common determinants …

Acquisition Strategy For Innovation Under Competence-Destroying Change: Empirical Study—Pharmaceutical Company's Biotechnology Company Acquisition, Joo Tae Sung

Dissertations and Theses Collection (Open Access)

In response to declining R&D productivity and successive patent cliffs, pharmaceutical companies are increasingly acquiring biotechnology firms to sustain innovation. These acquisitions often occur under conditions of competence-destroying change, where the acquirer's chemistry-based knowledge base does not overlap with the biotechnology expertise of the target, challenging traditional theories that emphasize absorptive capacity and knowledge similarity.
This study introduces therapeutic knowledge, defined as the acquirer’s expertise in specific disease areas, as a distinct and critical dimension that interacts with both chemistry-based and biotechnology-based knowledge. Using a dataset of 212 observations across therapeutic areas from 80 acquisitions, the analysis uncovers an inverted …

Rationale And Justification Of The Overarching Principles In The Governance Maturity Framework, Janna Wong, Eugene K. B. Tan, Steve Loh

Lien Centre for Social Innovation: Research

This research addresses the lack of a unified framework for measuring the governance maturity of impact organisations across countries with diverse legal landscapes and cultures, which complicates international assessment and collaboration. In response, we propose a governance framework tailored to the legal context of six countries: India, Indonesia, Malaysia, the Philippines, Singapore, and Thailand. Our analysis identifies six overarching principles embedded in the non-profit laws of the six countries: (1) purpose and impact, (2) leadership, (3) integrity, (4) communication, (5) efficacy, and (6) financial transparency and accountability. These six overarching principles form the proposed framework, which was operationalised and further …

On-Demand Scenario Generation For Testing Automated Driving Systems, Songyang Yan, Xiaodong Zhang, Kunkun Hao, Haojie Xin, Yonggang Luo, Jucheng Yang, Ming Fan, Chao Yang, Jun Sun, Zijiang Yang

Research Collection School Of Computing and Information Systems

The safety and reliability of Automated Driving Systems (ADS) are paramount, necessitating rigorous testing methodologies to uncover potential failures before deployment. Traditional testing approaches often prioritize either natural scenario sampling or safety-critical scenario generation, resulting in overly simplistic or unrealistic hazardous tests. In practice, the demand for natural scenarios (e.g., when evaluating the ADS's reliability in real-world conditions), critical scenarios (e.g., when evaluating safety in critical situations), or somewhere in between (e.g., when testing the ADS in regions with less civilized drivers) varies depending on the testing objectives. To address this issue, we propose the On-demand Scenario Generation (OSG) Framework, …

Ef21 With Bells & Whistles: Six Algorithmic Extensions Of Modern Error Feedback, Ilyas Fatkhullin, Igor Sokolov, Eduard Gorbunov, Zhize Li, Peter Richtarik

Research Collection School Of Computing and Information Systems

First proposed by Seide (2014) as a heuristic, error feedback (EF) is a very popular mechanism for enforcing convergence of distributed gradient-based optimization methods enhanced with communication compression strategies based on the application of contractive compression operators. However, existing theory of EF relies on very strong assumptions (e.g., bounded gradients), and provides pessimistic convergence rates (e.g., while the best known rate for EF in the smooth nonconvex regime, and when full gradients are compressed, is O(1/T2/3), the rate of gradient descent in the same regime is O(1/T)). Recently, Richtàrik et al. (2021) proposed a new error feedback mechanism, EF21, based …

Your Past Is My Present: Does Evoking Historical Analogies Change Public Opinion Regarding Foreign Policy?, Anil Menon, Yehonathan Abramson, Dean C. Dulay, Pauline Jones

Research Collection School of Social Sciences

Historical analogies are often employed as tools of public persuasion on security and foreign policies. While existing research points to the potential power of historical analogies on domestic audiences, it has not examined the effect of historical analogies on foreign publics. Using speeches by Ukrainian President Volodymyr Zelensky after Russia’s February 2022 invasion, we investigate whether evoking salient events from the audience country’s past effectively increases popular support for aiding Ukraine. We conducted survey experiments simultaneously in four countries where Zelensky delivered speeches rich in historical analogies – United Kingdom (WWII), United States (Pearl Harbor and 9/11), Germany and Israel …

Advocacy Under Authoritarianism: Civil Society's Impact On Environmental Treaty Ratification In Southeast Asia, Christianna Sirindah Parr

Research Collection School of Social Sciences

Does civil society in competitive authoritarian and authoritarian countries impact environmental policy? Specifically, does civil society speed up the ratification of international environmental treaties? Treaty ratification is a crucial step for translating international commitments to domestic politics. I argue that in competitive authoritarian regimes, where civil society operates under constraints but retains some space for advocacy, more robust civil society accelerates the ratification of environmental treaties compared to states with weaker civil society. These regimes often tolerate civil society pressure on non-threatening issues, such as environmental governance, which allows for strategic concessions without undermining state authority. Focusing on Southeast Asia, …

Predicting Consumers’ Purchase Intention Of Browsed Products: A Study Based On Eye‑Tracking, Feiyan Jia, Choon Ling Sia, Yani Shi, Fiona Fui-Hoon Nah, Keng Siau

Research Collection School Of Computing and Information Systems

Predicting consumers’ purchase intention of browsed products enables sellers to implement nuanced promotion strategies to stimulate purchase. But how can we predict consumers’ purchase intention of browsed products? Our research demonstrates that consumers’ eye movement data collected when they browse products can serve this aim. We train and test the prediction model using logistic regression and random forest algorithms. Using data collected in a laboratory experiment, our empirical results show that both algorithms perform much better than a random guess, and the logistic regression performs slightly better than the random forest. Our findings imply that eye movement data enable sellers …
