Navigating Unemployment Without Unemployment Insurance: Evidence From Singapore, Kim, Lanjie Wang

Research Collection School Of Economics

This study investigates the short-term impacts of unemployment among older workers (aged 50–62) in Singapore, a setting with-out public unemployment insurance. Using monthly panel data from the Singapore Life Panel, we analyse dynamic effects onmajor life outcomes such as income, spending, health, and subjective wellbeing over 2 years post-unemployment. Our findingsreveal substantial initial earnings losses with incomplete recovery: income remains 50.7% below pre-unemployment levels after24 months. Despite this persistent income gap, total household expenditure declines by 9.8% on average over 2 years (rangingfrom 7% to 16% across months). The implied two-year marginal propensity to consume is about 0.182, smaller than …

The Effect Of Vaccine Mandates On Disease Spread: Evidence From College Covid-19 Mandates, Riley K. Acton, Wenjia Cao, Emily E. Cook, Scott A. Imberman, Michael F. Lovenheim

Research Collection School Of Economics

Nearly 700 4-year U.S. colleges mandated students receive COVID-19 vaccinations in fall 2021. Using data on college policies and county health, we estimate how mandates affect surrounding communities. Event studies from August to November 2021 show that mandates covering all colleges in a county reduced COVID-19 deaths by 5.6 per 100,000 persons, a 4.6% reduction in the U.S. total during this period. Mandates reduced COVID cases by 504 and ICU admissions by 16.2 per 100,000, though we see no statistically significant impact on hospitalizations. Impacts are larger in counties with larger college populations and low estimated ex-ante student vaccination rates.

Social Mobility Beliefs Predict Competence Stereotype Gaps Between The Poor And Rich, Gregory Tee Hng Tan

Dissertations and Theses Collection (Open Access)

The poor tend to be viewed as less competent than the rich. This dissertation examined whether social mobility beliefs shape perceived rich-poor competence gaps. When society is seen as highly mobile, people may attribute economic outcomes to internal abilities than external constraints, thereby widening the rich-poor competence gap. Conversely, perceiving low mobility may shift explanations away from internal abilities toward external constraints and narrow the gap. Four studies tested this theory. Study 1 examined the relationships between self-reported mobility beliefs, attributions, and competence of rich and poor targets among Singapore and UK participants. While higher mobility beliefs predicted stronger internal …

The Unintended Consequences Of International Student Shortage: Evidence From South Korea, Chung-Yoon Choi, Syngjoo Choi, Seonghoon Kim, Jongkwan Lee

Research Collection School Of Economics

We study the role of international students in the higher education sector and the local economy by exploiting a policy reform in South Korea that restricted the admission of foreign students to local universities. By comparing the pre- and post-reform differences across universities with different pre-reform shares of international student enrollment, we show that an international student shortage resulting from this policy reform significantly worsened the financial outcomes of universities and consequently led to reduced investment in their students. We also document that a reduction in the number of international students in local areas decreased native employment, mainly in low-skilled …

Patent Regime Shift And Firm Innovation Strategy: Evidence From The Second Amendment To China's Patent Law, Tony W. Tong, Wenlong He, Liang Chen, Zi-Lin He, Jiangyong Lu

Research Collection Lee Kong Chian School Of Business

Research Summary: While changes in intellectual property rights (IPR) protection significantly shape firm innovation, the mechanisms driving firms' responses remain poorly understood. Leveraging the Second Amendment to China's Patent Law, which strengthens appropriability particularly for state-owned enterprises (SOEs), as a natural experiment, we show that stronger IPR has mixed effects on SOEs' innovation. While SOEs increase the rate of innovation subsequent to the Amendment, they shift the direction of innovation toward more familiar areas in which they face a lesser need to adjust existing routines. This directional change suggests a quality decline in SOEs' innovation that may be attributed to …

Through The Lens Of Clarity: Perceived Organizational Tightness Boosts Creativity For Men, But Not For Women, Grace J. H. Lim, Roy Y. J. Chua

Research Collection Lee Kong Chian School Of Business

A commonly held perspective in the cultural tightness literature is that cultural tightness tends to negatively impact creativity. Yet some findings indicate that this relationship is not strictly negative and that a more nuanced perspective should be considered. Drawing on social information processing (SIP) theory and social role theory, we build theory on how the perception of organizational cultural tightness can increase creativity for some employees, but not for others. Specifically, we propose that perceived organizational tightness—the extent to which one perceives that an organization is characterized by strong norms and sanctions for deviation—increases clarity on creativity evaluation standards and …

Late-Night And Early-Morning Train Scheduling With Non-Traffic Hour Maintenance Window In Urban Rail Transit Systems, Yaochen Ma, Hai Yang, Hai Wang

Research Collection School Of Computing and Information Systems

Regular maintenance during non-traffic hours (NTH) is vital for the resilience of urban rail transit (URT) systems, yet an insufficient NTH maintenance window poses a challenge for URT systems in various cities. For instance, the Hong Kong MTR Corporation has noted that the required NTH maintenance time often exceeds the available window, prompting service adjustments such as earlier late-night closures and/or later early-morning starts. To address this challenge, this study develops an optimal scheduling framework that links late-night and early-morning URT services through the NTH maintenance window requirement to maximize public welfare. A Decoupled Optimization Model (DOM) first derives closed-form …

Modeling And Forecasting Intraday Spot Volatility, Adam Clements, Daniel P. A. Preve

Research Collection School Of Economics

We propose a multiple-equation regression-based method for modeling and forecasting intraday spot volatility. In this approach, intraday intervals are treated as individual time series, deviating from the common practice of treating the data as one continuous sample. Our empirical study, which spans more than two decades and encompasses six US blue-chip stocks, employs the recent OK volatility estimator developed by Li, Wang, and Zhang (2024) to expose the dynamics of latent intraday spot volatility over time. We demonstrate that the proposed method effectively captures the intricate dynamics of intraday spot volatility and find strong evidence that it outperforms a competing …

Occupation Ladders Over The Business Cycle, Ismail Baydur, Toshihiko Mukoyama

Research Collection School Of Economics

This paper studies occupational mobility over the business cycle. We divide occupations into two broad groups, “attractive” and “nonattractive”, where we label an occupation attractive if the total net inflow into this occupation through job-to-job transition is positive. We measure total net inflows into both occupation groups. We measure these inflows separately for job-to-job transitions and transitions from unemployment to employment. We find that the net inflow from nonattractive to attractive occupations through job-to-job transitions slows during recessions. The net inflow through transitions from unemployment has a similar cyclicality. This finding suggests a novel cost of recession: during recessions, workers …

How Do Sectoral Shocks Shape Future Gdp?, Paul Ho, Danial Lashkari, Pierre-Daniel Sarte

Research Collection School Of Economics

A production sector’s size, as measured by its Domar weight, captures the contemporaneous aggregate effect of its productivity shocks. Any future aggregate effects, however, depend on that sector’s participation in the investment network. We derive a dynamic generalization of Hulten’s theorem in an environment with intermediate-input and investment networks. This generalization, implied by production efficiency alone, decomposes each sector’s Domar weight into an impact and a propagation component. The relative size of these components then determines how persistent the aggregate effects of sectoral shocks are, but cannot be known absent information on the economy’s production structure. We show in a …

Sustainable Rural Development Under Ecological Civilization: Two Mountains Theory, “Green Rural Revival”, And Post-Productivist Transition In Zhejiang, Qian Forrest Zhang, Jianzhang Luo, Li Zhou

Research Collection School of Social Sciences

Existing studies of China’s overarching ideological framework for national development, “Ecological Civilization”, have focused narrowly on environmental governance; how it reshapes sustainable rural development remains underexplored. This paper pursues two analytically distinct tasks. First, it reconstructs the policy history of how President Xi Jinping’s “Two Mountains” theory was incorporated into the Eco-civilization framework and how Zhejiang Province’s “Green Rural Revival” (GRR) program, as a lived example of Eco-civilization, was elevated as the national template for rural development in 2024. Second, drawing on three cases from a sample of 21 villages in Zhejiang, it identifies three core practices of GRR and …

Online Planning Of Power Flows For Power Systems Against Bushfires Using Spatial Context, Jianyu Xu, Qiuzhuang Sun, Yang Yang, Huadong Mo, Daoyi Dong

Research Collection College of Integrative Studies

A power station or transmission line can be affected due to bushfires, increasing operation costs. We study a fundamental but challenging problem of planning the optimal power flow (OPF) for power systems under bushfires. We develop a model to capture the stochastic nature of bushfire spread based on Moore’s neighborhood model and propose an online optimization modeling framework to sequentially plan power flows in the electricity network. Our framework assumes that bushfire spread is non-stationary over time and that the spread and containment probabilities are unknown. To address these challenges, we develop a contextual online learning algorithm that treats the …

The Allure Of A Slow Life Strategy: How Mating Context And Ecological Harshness Shape Mate Preferences, Lynn K. L. Tan, Nicole Ruiying Chen, Kenneth Tan, Norman P. Li

Research Collection School of Social Sciences

Although mate preferences have been extensively studied across various factors such as physical attractiveness or social status, their connection to life history strategy remains underexplored. Specifically, do individuals prefer mates who display signs of a fast or slow strategy? And what might qualify these preferences? Drawing from life history theory, we suggest that mate preferences are sensitive to cues of prospective mates' life history strategy, and that these preferences are malleable and shaped by ecological conditions. We hypothesize that in general, individuals will favor slow (versus fast) strategists as a mate. This is because modern environments are generally defined by …

Personal Goal Facilitation, Burnout And Work Engagement: The Role Of Self-Discrepancy, Jacinth Jia Xin Tan, Bek Wuay Tang

Research Collection School of Social Sciences

Employees who perceive greater personal goal facilitation through work (PGFW) experience lower burnout and higher work engagement. This research examined whether self-discrepancies and emotional experiences explain these relationships across two cross-sectional studies involving a nationally representative sample of working adults (Study 1; N = 889) and a sample of public school teachers (Study 2; N = 228) in Singapore. Participants listed personal goals and rated how much their jobs facilitated these goals, alongside measures of self-discrepancy, emotions, burnout, and engagement. Across both samples, higher PGFW predicted lower burnout and greater engagement. These associations were consistently explained by lower ideal self-discrepancy …
