Essays On Estimating Firm-Level Production Function With Spatial Dependence, Bo Lin Ng Jul 2024

Essays On Estimating Firm-Level Production Function With Spatial Dependence, Bo Lin Ng

Dissertations and Theses Collection (Open Access)

This dissertation consists of two chapters on the estimation of firm-level production functions when spatial effects are present. In joint work with Pao-Li Chang, chapter 1 focuses on the impacts of global value chains (GVC) on the firm-level outcomes of Singapore. First, we quantify Singapore’s participation in global value chains (GVC) using the export decomposition framework of Borin and Mancini (2019), before using these indicators to analyse how GVC participation affects sectoral-level valueadded and employment. We find that gross exports and foreign final demand have become more important for Singapore’s value-added, largely driven by the Services sectors. We then use …

The Role Of Executive Function In Cognitive Reappraisal: A Meta-Analytic Review, Wei Xing Toh, Jun Sheng Keh, James J. Gross, Laura L. Carstensen Jul 2024

The Role Of Executive Function In Cognitive Reappraisal: A Meta-Analytic Review, Wei Xing Toh, Jun Sheng Keh, James J. Gross, Laura L. Carstensen

Research Collection School of Social Sciences

Cognitive reappraisal refers to the reinterpretation of a situation to alter its emotional meaning. Theoretically, executive functions (EFs), such as inhibition, updating, and shifting, are core elements of reappraisal processes. However, empirical studies have yielded inconsistent evidence as to whether and to what extent EFs are associated with reappraisal. To address this issue, we conducted a meta-analysis of the literature in which 179 effect sizes from 59 independent samples (N = 4,703) were included. Using random-effects metaregression with robust-variance estimates and small-sample corrections, we also examined whether variation in effect sizes could be accounted for by potential moderators, such as …


Relationship Commitment Regulation: Influencing A Partner's Commitment To Achieve One's Commitment Goals, Laura V. Machia, Kenneth Tan, Christopher R. Agnew Jul 2024

Relationship Commitment Regulation: Influencing A Partner's Commitment To Achieve One's Commitment Goals, Laura V. Machia, Kenneth Tan, Christopher R. Agnew

Research Collection School of Social Sciences

We introduce a model of relationship commitment regulation, which describes how romantic partners might use empirically-validated antecedents of commitment level strategically to influence a partner's commitment toward their relationship based on certain commitment goals they have for the relationship. People are generally aware of and relatively accurate with respect to knowing their partner's level of commitment and also have preferences regarding their desired level. We summarize key antecedents of commitment level (i.e., satisfaction level, alternative quality, investment size, future plans, and subjective norms) and then describe how each can be manipulated via relationship maintenance activities to move a partner's commitment …


Report On Findings From Household Needs Study, Paulin T. Straughan, Mathew Mathews Jul 2024

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 …


Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young Jul 2024

Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young

Research Collection School of Social Sciences

The expanding footprint of urban Asian settlements and increasing living standards have put pressure on cemetery sites. Public health narratives and the sanctity associated with death matters in Asian urban landscapes have fed into the rhetoric of cemeteries as undesirable heritage spaces. Often lacking protection, many cemeteries have been exhumed, cleared, and relocated to allow room for new developments and infrastructure, risking the survival of this quiet element of the urban cultural patrimony. Within an Asian context, synergies between nature and cultural heritage preservation are not prevalent in major cities like Singapore, Hong Kong, Tokyo, Manila, Kuala Lumpur, and Bangkok. …


Cash, Crowds, And Cooperation: The Effects Of Population Density And Resource Scarcity On Cooperation In The Dictator Game, Tan Kai Lin, Lynn, Norman P. Li, Kenneth Tan Jul 2024

Cash, Crowds, And Cooperation: The Effects Of Population Density And Resource Scarcity On Cooperation In The Dictator Game, Tan Kai Lin, Lynn, Norman P. Li, Kenneth Tan

Research Collection School of Social Sciences

The adaptive benefits of cooperation among humans have been widely studied. However, is being cooperative always adaptive across various combinations of ecological conditions? Existing work has focused on cultural, inter-, and intra-individual predictors of cooperation yet there is a lack of research on how an individual's ecology may come into play. In this work, we focus on the interaction of two ecological factors—population density and resource scarcity—on cooperation. Population density is often accompanied by social competition for limited resources. We hypothesise that in response to cues of high (versus low) population density, people facing resource-scarcity would adaptively lower their cooperativeness, …


Hot At The Top: The Influence Of Self-Rated Attractiveness On Self-Perceived Status, Lynn K. L. Tan, Michal Folwarczny, Tobias Otterbring, Norman P. Li Jul 2024

Hot At The Top: The Influence Of Self-Rated Attractiveness On Self-Perceived Status, Lynn K. L. Tan, Michal Folwarczny, Tobias Otterbring, Norman P. Li

Research Collection School of Social Sciences

Beautism reflects the phenomenon of a widespread positivity bias that physically attractive people enjoy. This bias results in more attractive people receiving more positive social judgments, interactions, and economic outcomes. However, the literature has largely focused on third-party judgments of physical attractiveness, neglecting examinations of how self-rated attractiveness may predict self-evaluations. We sought to address this gap by examining how self-rated attractiveness predicts self-inferred social status, which is related to a myriad of psychosocial outcomes. Across one pilot test, one cross-sectional study, and a between-subjects experiment, we find converging evidence for the notion that self-rated physical attractiveness positively predicts higher …


Competing With The Platform: Complementor Positioning And Cross-Platform Response To Entry, Aldona Kapacinskaite, Ahmadreza Mostajabi Jul 2024

Competing With The Platform: Complementor Positioning And Cross-Platform Response To Entry, Aldona Kapacinskaite, Ahmadreza Mostajabi

Research Collection Lee Kong Chian School Of Business

Research SummaryThis study contrasts traditional entry dynamics with platform owner entry into a complementor market and examines cross-platform complementor response to competition with the platform. Generalists experience low repositioning cost and are more likely to shift effort away, while specialists focus their effort on the focal platform. We examine Apple's “Files” app entry and find support for our hypotheses: generalists shift effort toward the competing platform, while specialists double down on the focal platform. Moreover, empirically comparing Apple's entry with that of other large firms, we find that only the platform owner elicits a strong complementor response. This article contributes …


Who Profits From Trading Options?, Jianfeng Hu, Antonia Kirilova, Gilbert Seongkyu Park, Doojin Ryu Jul 2024

Who Profits From Trading Options?, Jianfeng Hu, Antonia Kirilova, Gilbert Seongkyu Park, Doojin Ryu

Research Collection Lee Kong Chian School Of Business

We use account-level transaction data to examine trading styles and profitability in a leading derivatives market. Approximately 66% of active retail investors predominantly hold simple, one-sided positions in only one class of options, whereas institutional investors are more likely to use complex strategies. Hypothesizing that the complexity of trading styles reflects investors' skills, we examine the effect of options trading styles on investment performance. We find that retail investors using simple strategies lose to the rest of the market. For both retail and institutional investors, selling volatility is the most successful strategy. We conclude that these style effects are persistent …


A Feasibility-Preserved Quantum Approximate Solver For The Capacitated Vehicle Routing Problem, Ningyi Xie, Xinwei Lee, Dongsheng Cai, Yoshiyuki Saito, Nobuyoshi Asai, Hoong Chuin Lau Jul 2024

A Feasibility-Preserved Quantum Approximate Solver For The Capacitated Vehicle Routing Problem, Ningyi Xie, Xinwei Lee, Dongsheng Cai, Yoshiyuki Saito, Nobuyoshi Asai, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

The Capacitated Vehicle Routing Problem (CVRP) is an NP-optimization problem (NPO) that arises in various fields including transportation and logistics. The CVRP extends from the Vehicle Routing Problem (VRP), aiming to determine the most efficient plan for a fleet of vehicles to deliver goods to a set of customers, subject to the limited carrying capacity of each vehicle. As the number of possible solutions increases exponentially with the number of customers, finding high-quality solutions remains a significant challenge. Recently, the Quantum Approximate Optimization Algorithm (QAOA), a quantum–classical hybrid algorithm, has exhibited enhanced performance in certain combinatorial optimization problems, such as …


Can A Tobin Tax Curb Speculation In The Housing Market? A Study On The Effect In The Primary Market Of Hong Kong Tax Policy, Dinh Tuan Dang Jul 2024

Can A Tobin Tax Curb Speculation In The Housing Market? A Study On The Effect In The Primary Market Of Hong Kong Tax Policy, Dinh Tuan Dang

Dissertations and Theses Collection (Open Access)

This study examines the effect of Special Stamp Duty (SSD) and Buyer's Stamp Duty (BSD) on Hong Kong’s housing prices in the primary market. Using micro transaction data, I show that the Tobin tax policies were not effective in cooling the primary market. The primary market responded differently when facing the two events. Specifically, SSD Phase 1 led to a 9.4% price increase within 6 to 12 months post-implementation, suggesting a lag effect. The introduction of SSD Phase 2 and BSD initially caused a significant 13.1% price surge in the first 6 months, but was followed by a notable 9% …


Health Insurance And The Rise Of Women: Evidence From The New Cooperative Medical Scheme, Xingyu Bai Jul 2024

Health Insurance And The Rise Of Women: Evidence From The New Cooperative Medical Scheme, Xingyu Bai

Dissertations and Theses Collection (Open Access)

Females are traditionally viewed as the primary providers of informal parental care in China, especially in rural areas. We investigate whether health insurance coverage in rural China, the New Cooperative Medical Scheme (NCMS), can unleash more female labor force participation by reducing the burden of informal parental care. Employing a heterogeneity-robust difference-in-differences estimation, we find that the NCMS has a significant positive impact on female labor supply, primarily in non-farm occupations. In contrast, we observe no significant changes in male labor supply. We explore the mechanism by showing that the NCMS significantly decreases both the provision and demand for parental …


Study On The Structural Influence Mechanism Of Robot Construction On Real Estate Project Costs: Moderating Effect Of Management Change, Xiujuan Wei Jul 2024

Study On The Structural Influence Mechanism Of Robot Construction On Real Estate Project Costs: Moderating Effect Of Management Change, Xiujuan Wei

Dissertations and Theses Collection (Open Access)

Cost control in construction is crucial for the survival of real estate enterprises. Especially in the context of cyclical downturns in the real estate industry, it is essential to achieve cost reduction and efficiency improvement in real estate projects. Currently, the widespread application of robotics technology may hold the key to achieving this goal. Robotics technology is widely recognized for its ability to automate tasks and reduce labor costs. However, it also brings about transformative impacts on management, organization, production, and processes, which can paradoxically increase project costs. Unfortunately, there is a lack of research focusing on the impact of …


Transportation, Healthcare Seeking, And Outcomes, Xiao Lin Ong Jul 2024

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 …


Executive Function And Feedback In Regulatory Monitoring: Towards An Understanding Of Flexible And Adaptive Emotion Regulation, Gilaine Rui Ng Jul 2024

Executive Function And Feedback In Regulatory Monitoring: Towards An Understanding Of Flexible And Adaptive Emotion Regulation, Gilaine Rui Ng

Dissertations and Theses Collection (Open Access)

Monitoring is a process which involves attending to feedback regarding the efficacy of ongoing regulatory strategies and determining whether to switch or maintain strategies (i.e., strategy switching or maintenance) in order to maximize adaptive outcomes. While conceptual accounts underscore the critical role of monitoring in flexible and adaptive emotion regulation, empirical research remains scarce, and the cognitive factors which subserve the monitoring process remain unclear and poorly understood. To bridge this gap, we investigate how components of executive function (EF)—a set of cognitive control processes necessary for flexible, goal-directed behavior—would differentially support the monitoring process. Additionally, we examine the extent …


Reading The Candlesticks: An Ok Estimator For Volatility, Jia Li, Dishen Wang, Qiushi Zhang Jul 2024

Reading The Candlesticks: An Ok Estimator For Volatility, Jia Li, Dishen Wang, Qiushi Zhang

Research Collection School Of Economics

We propose an Optimal candlesticK (OK) estimator for the spot volatility using high-frequency candlestick observations. Under a standard infill asymptotic setting, we show that the OK estimator is asymptotically unbiased and has minimal asymptotic variance within a class of linear estimators. Its estimation error can be coupled by a Brownian functional, which permits valid inference. Our theoretical and numerical results suggest that the proposed candlestick-based estimator is much more accurate than the conventional spot volatility estimator based on high-frequency returns. An empirical illustration documents the intraday volatility dynamics of various assets during the Fed chairman's recent congressional testimony.


Bubbly Booms And Welfare, Feng Dong, Yang Jiao, Haoning Sun Jul 2024

Bubbly Booms And Welfare, Feng Dong, Yang Jiao, Haoning Sun

Research Collection School Of Economics

We show the competing effects of a housing bubble on the real economy by developing a multi-sector dynamic model with housing production. On the one hand, firms can sell or collateralize their housing, so a housing bubble helps firms obtain credit to finance their investment and expand production. On the other hand, a boom in the housing sector crowds out labor in the non-housing sector. We show that housing booms can reduce social welfare both in the steady state and in the transitional dynamics only when the production externalities in the non-housing sector are sufficiently large. We quantitatively evaluate our …


Rank-Guaranteed Auctions, Wei He, Jiangtao Li, Weijie Zhong Jul 2024

Rank-Guaranteed Auctions, Wei He, Jiangtao Li, Weijie Zhong

Research Collection School Of Economics

We propose a combinatorial ascending auction that is “approximately” optimal, requiring minimal rationality to achieve this level of optimality, and is robust to strategic and distributional uncertainties. Specifically, the auction is rankguaranteed, meaning that for any menu M and any valuation profile, the ex-post revenue is guaranteed to be at least as high as the highest revenue achievable from feasible allocations, taking the (|M| + 1)th-highest valuation for each bundle as the price. Our analysis highlights a crucial aspect of combinatorial auction design, namely, the design of menus. We provide simple and sufficient menus in various settings.


Coarse Revealed Preference, Gaoji Hu, Jiangtao Li, John K-H Quah, Rui Tang Jul 2024

Coarse Revealed Preference, Gaoji Hu, Jiangtao Li, John K-H Quah, Rui Tang

Research Collection School Of Economics

We propose a novel concept of rationalization, called coarse rationalization, tailored for the analysis of datasets where an agent’s choices are imperfectly observed. We characterize those datasets which are rationalizable in this sense and present an efficient algorithm to verify the characterizing condition. We then demonstrate how our results can be applied through a duality approach to test the rationalizability of datasets with perfectly observed choices but imprecisely observed linear budget sets. For datasets that consist of both perfectly observed feasible sets and choices but are inconsistent with perfect rationality, our results could be used to measure the extent to …


Comparative Analysis Of Hate Speech Detection: Traditional Vs. Deep Learning Approaches, Haibo Pen, Nicole Anne Huiying Teo, Zhaoxia Wang Jul 2024

Comparative Analysis Of Hate Speech Detection: Traditional Vs. Deep Learning Approaches, Haibo Pen, Nicole Anne Huiying Teo, Zhaoxia Wang

Research Collection School Of Computing and Information Systems

Detecting hate speech on social media poses a significant challenge, especially in distinguishing it from offensive language, as learning-based models often struggle due to nuanced differences between them, which leads to frequent misclassifications of hate speech instances, with most research focusing on refining hate speech detection methods. Thus, this paper seeks to know if traditional learning-based methods should still be used, considering the perceived advantages of deep learning in this domain. This is done by investigating advancements in hate speech detection. It involves the utilization of deep learning-based models for detailed hate speech detection tasks and compares the results with …


Toward Effective Secure Code Reviews: An Empirical Study Of Security-Related Coding Weaknesses, Wachiraphan Charoenwet, Patanamon Thongtanunam, Thuan Pham, Christoph Treude Jul 2024

Toward Effective Secure Code Reviews: An Empirical Study Of Security-Related Coding Weaknesses, Wachiraphan Charoenwet, Patanamon Thongtanunam, Thuan Pham, Christoph Treude

Research Collection School Of Computing and Information Systems

Identifying security issues early is encouraged to reduce the latent negative impacts on software systems. Code review is a widely-used method that allows developers to manually inspect modified code, catching security issues during a software development cycle. However, existing code review studies often focus on known vulnerabilities, neglecting coding weaknesses, which can introduce real-world security issues that are more visible through code review. The practices of code reviews in identifying such coding weaknesses are not yet fully investigated. To better understand this, we conducted an empirical case study in two large open-source projects, OpenSSL and PHP. Based on 135,560 code …

We live in a hyperconnected world. Ecosystems and societies are linked across vast distances like never before. The unprecedented movement of people, goods and products and the transfer of capital and information characterise not only the present but also the conceivable future. Use of the term ‘hyperconnected world’ started to gain traction in the literature towards the turn of this millennium. Mainstreaming of the internet across societies led to the exploration of global hyperconnectivity across a range of spheres including business, investment and computing. The term gained further prominence with its use by the World Economic Forum in the early …


Broken Kinship: Family Property Disputes And The Common Intention Constructive Trust In Singapore, Hang Wu Tang Jul 2024

Broken Kinship: Family Property Disputes And The Common Intention Constructive Trust In Singapore, Hang Wu Tang

Research Collection Yong Pung How School Of Law

There has been a proliferation of common intention constructive trust claims in Singapore. The main reason is that families have acquired real estate using their collective earning power without explicitly considering the individual entitlement of each family member. When a dispute arises, the claim is often pleaded as a common intention constructive trust. The complication with applying the law on the common intention constructive trust is that this is an English doctrine developed to deal with a different social context i.e. the breakdown of the relationship between cohabiting couples. In Singapore, the common intention constructive trust applies primarily in a …

Establishing Marine Protected Areas In The Southern Ocean, Lessons For The Bbnj Agreement, Nengye Liu Jul 2024

Establishing Marine Protected Areas In The Southern Ocean, Lessons For The Bbnj Agreement, Nengye Liu

Research Collection Yong Pung How School Of Law

This paper first gives a brief overview of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)’s struggle to establish Antarctic Marine Protected Areas (MPAs). The paper then addresses the question: what lessons can countries learn from CCAMLR's experience in establishing high seas MPAs under the Biodiversity in Areas Beyond National Jurisdiction (BBNJ) Agreement? The paper finds that the final text of the BBNJ Agreement did largely reflect CCAMLR's experience when it comes to MPAs. This is particularly so with respect to 1) clarification of the relationship between conservation and use; 2) the interpretation and application of a …


Gamified Bodies And The Illusory Meaning Of Muscle, Orlando Woods Jul 2024

Gamified Bodies And The Illusory Meaning Of Muscle, Orlando Woods

Research Collection College of Integrative Studies

This paper foregrounds the agency of the body to explore how it is “gamified” in the pursuit of a desired self-image. Gamified bodies are those that are tricked into metabolising in ways that suit the representational aspirations of the self. The aspirations that I consider in this paper are those of muscle, and how individuals trying to build muscle pursue various metabolic tricks to try and overcome, or otherwise suppress, the in-built agency of the body. Exploring and understanding these tricks contributes to feminist understandings of the body generally, and of muscle specifically, and its unruly nonconformity to the gendered …


Insourcing The Smart City: Assembling An Ideo-Technical Ecosystem Of Talent, Skills, And Civic-Mindedness In Singapore, Orlando Woods, Tim Bunnell, Lily Kong Jul 2024

Insourcing The Smart City: Assembling An Ideo-Technical Ecosystem Of Talent, Skills, And Civic-Mindedness In Singapore, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article examines an alternative model of smart city formation, one based on the principle of insourcing technical competencies and capabilities to those responsible for city governance. This model counters the logic of technological outsourcing upon which many assumptions and critiques of the smart city rest, and thus reveals ways in which a more generative discourse can be forged. Drawing on a series of in-depth interviews with senior stakeholders from public and private sector organizations, we develop a case study of Singapore’s Smart Nation initiative. Through coordinated efforts to reorganize the public sector’s technological functions, develop nation-wide skills upgrading programs, …
