Essays On Empirical Asset Pricing, Qi Fan

Dissertations and Theses Collection (Open Access)

My dissertation consists of three studies on how investor behavior affects the outcomes in financial markets. The first study focuses on the investors’ limited capacity on processing the complicated information transmitted through interconnected firms. The other two studies explore the investor heterogeneity on preferred time of trading, due to their personal traits or irrational judgements on the market conditions.

In Chapter 2, I focus on the return predictability across economically linked firms, due to investor limited attention. I document significant outperformance of stocks whose industry peers currently experience salient (attention-grabbing) gains, especially for those with strong social ties. The long-short …

Essays On Labor And Family Economics, Yutao Wang

Dissertations and Theses Collection (Open Access)

This dissertation comprises three chapters that investigate the trade-offs between the quantity and quality of children, as well as trade-offs between female labor supply and family formation.

The first chapter investigates how family size shapes child migration in China, where most rural families have at least two children, and nearly 50% of children have migrant parents. We propose a model showing that, conditional on family size, boys and girls are equally likely to migrate with parents to cities. However, in societies with strong son preference, daughters' migration may still be constrained as they tend to have more siblings, and larger …

Flow Experience In Immersive Tourism Performance: Antecedents And Tourists’ Satisfaction, Xiaoli Zhu

Dissertations and Theses Collection (Open Access)

With the deep integration of culture and tourism, immersive tourism performance has emerged as a new form of experiential consumption and has gradually become an essential vehicle for shaping destination branding and enhancing tourists’ cultural identity. By breaking the boundaries of traditional stages and integrating spatial construction, narrative mechanisms, and multidimensional interactive experiences, immersive performances create a sense of presence and immersion for tourists. This study focuses on the mechanism influencing tourists’ flow experience and satisfaction in immersive tourism performances. A theoretical model incorporating authenticity, interactivity, sense of presence, and value congruence was constructed and tested to reveal how multidimensional …

Estimation And Inference In A Possibly Multicointegrated System With A Fixed Number Of Instruments, Yixiao Sun, Peter C. B. Phillips, Igor L. Kheifets

Research Collection School Of Economics

This paper shows that the mixed normal asymptotic limit of the trend IV estimator with a fixed number of deterministic instruments (fTIV) holds in both singular (multicointegrated) and nonsingular cointegration systems, thereby relaxing the exogeneity condition in (Phillips and Kheifets, 2024, Theorem 1(ii)). The mixed normality of the limiting distribution of fTIV allows for asymptotically pivotal F and t tests about the cointegration parameters and for simple efficiency comparisons of the estimators for different numbers K of instruments, as well as comparisons with the trend IV estimator when K→∞ with the sample size.

Statistical Inference For Noisy Matrix Completion Incorporating Auxiliary Information, Shujie Ma, Po-Yao Niu, Yichong Zhang, Yinchu Zhu

Research Collection School Of Economics

This article investigates statistical inference for noisy matrix completion in a semi-supervised model when auxiliary covariates are available. The model consists of two parts. One part is a low-rank matrix induced by unobserved latent factors; the other part models the effects of the observed covariates through a coefficient matrix which is composed of high-dimensional column vectors. We model the observational pattern of the responses through a logistic regression of the covariates, and allow its probability to go to zero as the sample size increases. We apply an iterative least squares (LS) estimation approach in our considered context. The iterative LS …

Digital Twin Dynamics: Employee’S Willingness To Adopt Ai Digital-Twin In A Craftsmanship Environment, Seow Hoon Tee

Dissertations and Theses Collection (Open Access)

Singapore’s manufacturing sector, contributing 22% to the nation’s GDP, is undergoing a strategic transformation under the Manufacturing 2030 vision, which aims to increase sector value by 50%. However, a critical challenge emerges in the widening age gap among craftsmen, particularly between 30 and 50 years old, misaligning with succession planning efforts. As senior craftsmen approach retirement, the urgency to transfer specialized expertise significantly increases. In response, initiatives such as the National AI Strategy (NAIS) 2.0 and Industry 5.0 efforts by the Singapore Manufacturing Federation (SMF) and Advanced Remanufacturing and Technology Centre (ARTC) emphasize AI-driven solutions to enhance knowledge retention and …

On Strategy-Proofness And The Salience Of Single-Peakedness In A Private Goods Allotment Problem, Shurojit Chatterji, Jordi Masso, Shigehiro Serizawa

Research Collection School Of Economics

We consider strategy-proof rules operating on a rich domain of preference profiles in a set up where multiple private goods have to be assigned to a set of agents with entitlements and where preferences display satiation. We show that if the rule is in addition tops-only, same-sided and individually rational with respect to the entitlements, then the preferences in the domain have to satisfy a variant of single-peakedness (referred to as multi-dimensional single-peakedness relative to the entitlements). We also provide a converse of this main finding. It turns out that this domain coincides with the one already identified in a …

Food Self-Sufficiency And Building-Integrated Urban Agriculture: Lessons From Singapore, Tomoki Fujii, Christoph Waibel, Xinyi Du, Zhongming Shi

Research Collection School Of Economics

Singapore aims to achieve 30 percent food self-sufficiency by 2030, known as the 30-by-30 target, and this paper reviews Singapore’s changing landscape for urban agriculture and its recent progress towards the 30-by-30 goal, highlighting key challenges such as land constraints, high production costs, and resource limitations. Building-integrated agriculture (BIA), which utilizes building surfaces such as rooftops, façades, and balconies for food production within urban environments, is examined as a potential way to increase self-sufficiency through a simulation. Despite the BIA’s potential, practical issues—including regulatory concerns and infrastructure limitations—must be addressed before it can be implemented at scale. Insights from Singapore’s …

By leveraging innovative technologies, fintech companies can reduce transaction costs, address information asymmetry issues and streamline processes such as customer evaluation and risk assessment. This strategic collaboration between banks and fintech firms can lead to improved efficiency and effectiveness in financial services, such as pressuring traditional banks to innovate in areas such as customer interface and processes, ultimately boosting economic growth.

Subway, Collaborative Matching, And Innovation, Yumi Koh, Li Jing, Jianhuan Xu

Research Collection School Of Economics

Using rapid expansion of the Beijing subway from 2000 to 2018, we analyze its impact on collaborative matches in innovations. We find that an hour reduction in travel time between a pair of locations in Beijing brought 14.85% to 37.69% increase in collaborated patents. Far-apart location pairs were more affected, and the local average causal response is approximately 34.92% to 82.29%. The effect is mainly driven by increased matches among highly productive innovators. The entry of new innovators, relocation of existing innovators, and collaborations among low-productive innovators also contribute to the increase in collaborative matches, especially in the long run.

How Do Insurance Companies Manage Reserves? Evidence From Reserve Errors Across Lines Of Business And Accident Years, Jing Rong Goh, Shinichi Kamiya, Pingyi Lou

Research Collection School Of Economics

We study the question of how insurance companies manage reserves. Specifically, we investigate how managerial incentives affect insurers’ reserving practice across lines of business (LOBs) and accident years (AYs). Because the tax discount factor the tax authority assigns varies across LOBs and AYs, insurers with stronger tax-saving incentives will be inclined to manage reserves across both LOBs and AYs. In contrast, since the Risk Based Capital (RBC) regime specifies different industry worst-case factors across LOBs, insurers with stronger incentives to increase their RBC ratio will be inclined to manage reserves across LOBs. Regarding income-smoothing incentives, only the overall level (and …

Consumption Responses To Income Shocks Through Lottery Winning, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

We study the effects of lottery winning on consumption spending using newly available household survey data in Singapore. We find strong consumption responses to a transitory income shock via lottery wins. Lottery winners spend about half of their prizes within 12 months of winning. We show that consumption responses are stronger among households with more binding liquidity constraints and less risk aversion, which is consistent with the standard life-cycle model. The strong consumption response suggests that fiscal stimulus policies or other public transfer programs could be an effective means of boosting consumption spending of the economy in the short run.

Something In The Air: Does Air Pollution Affect Fund Managers’ Carbon Divestment?, Thanh Huynh, Frank Weikai Li, Ying Xia

Research Collection Lee Kong Chian School Of Business

We examine whether fund managers overestimate carbon risk when they are exposed to local air pollution. We find that air pollution causes managers to underweight stocks of high-emission firms. The effects are stronger for less salient scopes of carbon emissions, among managers located in pro-environmental states, and among those likely to be surprised by air pollution—consistent with the idea that managers revise their beliefs about climate-transition risk following their exposure to air pollution. Carbon-intensive stocks sold by managers who are exposed to air pollution subsequently outperform stocks that they buy, suggesting that such underweighting is costly to fund investors.

Bogging Down Investors: An Unintended Consequence Of Litigation Risk, Siwen Fu, Ke Wang, Liandong Zhang, Liu Zheng

Research Collection School Of Accountancy

Securities litigation risk is a well-recognized yet underexplored source of financial reporting complexity or unreadability. This study examines the effect of litigation risk on the readability of corporate financial reports. The 1999 Silicon Graphics Inc. (SGI) court ruling unexpectedly reduced litigation risk for firms within the Ninth Circuit Court’s jurisdiction. Using a difference-in-differences design centered on the SGI court ruling, we find that, while the readability of financial reports generally declines over the sample period, treated firms in the Ninth Circuit experience a comparatively smaller decline in readability than control firms in other states after the ruling. Put differently, treated …

The Gender Wage Gap In An Online Labor Market: The Cost Of Interruptions, Abi Adams, Kotaro Hara, Kristy Milland, Chris Callison-Burch

Research Collection School Of Computing and Information Systems

This paper analyses gender differences in working patterns and wages on Amazon Mechanical Turk, a popular online labour platform. Using information on 2 million tasks, we find no gender differences in task selection nor experience. Nonetheless, women earn 20% less per hour on average. Gender differences in working patterns are a significant driver of this wage gap. Women are more likely to interrupt their working time on the platform with consequences for their task completion speed. A follow-up survey shows that the gender differences in working patterns and hourly wages are concentrated amongst workers with children.

Young Women In Cities: Urbanization And Gender-Biased Migration, Yumi Koh, Jing Li, Yifan Wu, Junjian Yi, Hanzhe Zhang

Research Collection School Of Economics

Young women outnumber young men in cities in many countries during periods of economic growth and urbanization. This gender imbalance among young urbanites is more pronounced in larger cities. We use the gradual rollout of Special Economic Zones across China as a quasi-experiment to establish the causal impact of urbanization on gender-differentiated incentives to migrate. We highlight the role of the marriage market in increasing rural women’s chance of marrying and marrying up in urban areas during rapid urbanization.

Redesigning Home Reversion Products To Empower Retirement For Singapore's Public Flat Owners, Koon Shing Kwong, Jing Rong Goh, Jordan Jie Xin Lee, Ting Lin Collin Chua

Research Collection School Of Economics

This paper introduces an innovative sell-type home reversion product aimed at monetizing Singapore’s public flats, serving as a new alternative to the existing Singapore Lease Buyback Scheme (LBS). This new product not only retains the LBS’s guaranteed period of residence in the property along with life annuity incomes but also enhances the product features to meet specific homeowner needs, including the ability to age in place, flexibility in retaining part of the property, options for bequests, and guaranteed principal return. By incorporating these additional features, the new product seeks to stimulate greater demand for monetizing public flats among asset-rich but …

Gauging Growth Risk In An International Financial Centre: Some Evidence From Singapore, Hwee Kwan Chow

Research Collection School Of Economics

This paper applies the growth-at-risk framework proposed by Adrian et al. (2019) to Singapore, an international financial centre whereby financial shocks are intermediated away quickly. We gauge near-term risks around growth projections taken from the survey of professional forecasters by accounting for financial stress in both local and global financial markets, as well as worldwide economic uncertainty. The conditioning variables are first linked to future growth through quantile regressions, and the estimated quantiles are fitted with skew t-distributions to produce full predictive distributions. Scenario analysis reveals that greater local financial strain tends to widen the uncertainty of growth outlook, higher …

Bank Competition Amid Digital Disruption: Implications For Financial Inclusion, Erica Xuewei Jiang, Yang Gloria Yu, Jinyuan Zhang

Sim Kee Boon Institute for Financial Economics

We study how digital disruption impacts bank competition, considering consumers’ heterogeneous digital preferences. We find that the rollout of 3G networks contracts bank branch networks and leads to divergence in branching and pricing strategies across banks. These developments benefit young consumers but increase the unbanked rate for poorer and older consumers. A structural model shows that the higher perceived digital quality by younger borrowers mainly prompts these adjustments, causing significant surplus losses for older savers. Counterfactual exercises illustrate that subsidizing older savers opting for mobile banking effectively offsets these disparities at minimal cost, facilitating a smoother digital transition.

The Scale Question As An Urban Question: The Making Of Homo Urbanicus Amid State Entrepreneurialism, Yong Zhang

Research Collection College of Integrative Studies

This research bridges two influential strands of literature on urban China—state entrepreneurialism and homo urbanicus (城市人). By revisiting how China’s post-reform urban transformation has unfolded and connecting it to current development strategies, this research provides a fresh perspective on the country’s urbanization processes and their implications for future governance. The analysis proposes an alternative periodization of three phases: anti-migration urbanism, anti-settlement urbanism, and anti-civitas urbanism. Beyond understanding urbanization as a crisis-driven, state-rescaling phenomenon pivoting around the blending of state and market forces, this research repositions the concept of homo urbanicus, or the urban citizen, as central to understanding the urban …

On The Decomposability Of Fractional Allocations, Shurojit Chatterji, Peng Liu

Research Collection School Of Economics

A common practice in dealing with the allocation of indivisible objects is to treat them as infinitely divisible and specify a fractional allocation, which is then implemented as a lottery on integer allocations that are feasible. The question we study is whether an arbitrary fractional allocation can be decomposed as a lottery on an arbitrary set of feasible integer allocations. The main result is a characterization of decomposable fractional allocations, that is obtained by transforming the decomposability problem into a maximum flow problem. We also provide a separate necessary condition for decomposability.

Is Subjective Well-Being Insured Against Income Shocks? Evidence From 20-Year Panel Data In South Korea, Jiyeon Ahn, Taehyun Ahn, Kim

Research Collection School Of Economics

Using 20 years of nationally representative panel data in South Korea, we estimate how life satisfaction responds to income shocks. We document that unexpected income changes significantly impact an individual's life satisfaction, and the magnitudes depend on the persistence of income shocks. We find that permanent income shocks substantially penetrate life satisfaction, while transitory income shocks have minimal impact. We also find that life satisfaction regarding external factors such as family income and leisure activities is more sensitive to income shocks than life satisfaction related to social relationships. Our findings imply that it is critical for the government to address …

Universal Return And Factor Timing, Poh Ling Neo, Chyng Wen Tee, Jeroen Kerkhof

Research Collection Lee Kong Chian School Of Business

The authors highlight the shortcomings of commonly used performance graphs in assessing and comparing investment returns. This paper's main conceptual contribution is the introduction of Universal Return (UR) - a visual method to evaluate and rank investment strategies that challenges the traditional focus on raw performance statistics. The authors argue that the ranking of investment performance when viewed from a pool of investors over different entry time is more important than its overall absolute returns, as it better aligns investment analysis with the needs of investors, who are primarily concerned with identifying currently successful strategies or managers rather than dwelling …

What Have Corporations Got To Do With It? A Political Economy Approach To Organizations And Climate Change, Annika Rieger

Research Collection School of Social Sciences

Ecological issues are often seen as only one of the many “problems” societies face today, even though they go deep and affect everything – from physical disruption and displacement to perhaps more subtle long-term changes in temperature, flora, and fauna that alter the face of the planet and the norms of everyday life. As a result of this view, the study of the environment has been siloed into the realm of “environmental sciences” with a few “environmental fill-in-the-social-science-blank” subfields scattered about. This is not to say that only “environmental” problems are important, but that across all disciplines and subfields, greater …

An Empirical Test Of Auction Efficiency: Evidence From Mbs Auctions Of The Federal Reserve, Pietro Bonadi, Ali Hortacsu, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

PurposeWe estimate the marginal cost curve of each dealer in each auction, based on structural models of the multiunit discriminatory-price auction.Design/methodology/approachAuction theory has ambiguous implications regarding the relative performance of three formats of multiunit auctions: uniform-price, discriminatory-price and Vickrey auctions. We evaluate the performance of these three auction formats using bid-level data of the Federal Reserve’s purchase auctions of agency MBS from June 2014 through November 2014.FindingsOur results suggest that neither uniform-price nor Vickrey auctions outperform discriminatory-price auctions in terms of the total expenditure. However, Vickrey auctions outperform discriminatory-price auctions in terms of efficiency, with the efficiency gain around 0.74% …

A Practical Guide To Driving Financial Inclusion Through Cbdcs, Heng Wang

Research Collection Yong Pung How School Of Law

Welcome back to our blog series exploring the potential that central bank digital currencies (CBDCs) hold to positively impact individuals that are currently unserved or underserved by financial systems globally. Together with Professor Wang, we first delved into the challenges and opportunities of driving financial inclusion, and how CBDCs could serve as an important mechanism in ensuring that no one is excluded from financial services – or our increasingly digital economies and societies. In our second blog we then examined how CBDCs can be intentionally designed to drive financial inclusion. In this third and final piece, Professor Wang offers a …

Optimal Har Inference, Liyu Dou

Research Collection School Of Economics

This paper addresses the problem of deriving heteroskedasticity and autocorrelation robust (HAR) inference for a scalar parameter of interest, under the assumption of a known upper bound on data persistence. Finite-sample optimal tests are derived within the Gaussian location model, revealing that robustness-efficiency tradeoffs are primarily determined by the maximal persistence. With a suitable adjustment to the critical value, the equal-weighted cosine (EWC) test emerges as nearly optimal, wherein the long-run variance is estimated through projections onto q type II cosines. This approach establishes a direct link between the choice of q and persistence assumptions, accompanied by adjustments to the …
