Monetary Policy Surprises, Stock Returns, And Financial And Liquidity Constraints, In An Exchange Rate Monetary Policy System, John M. Sequeira

Research Collection Lee Kong Chian School Of Business

This study examines the impact of monetary policy surprises on the stock price behaviour of a small developed economy, whose monetary policy is based on the exchange rate. We find that monetary policy surprises associated with all contractionary policy levers and a neutral policy lever, have a consistently significant and negative impact on stock returns. In comparison, only monetary policy surprises associated with a downward re-centering policy lever, has a significantly positive effect on stock returns. Using a recalibrated classification system, we also find that monetary policy surprises differ across sectors of the economy. Our results show how monetary policy …

To Stay Or Not To Stay? A Clash Of Arbitration And Insolvency Regimes, Darius Chan, Sidharrth B Rajagopal

Research Collection Yong Pung How School Of Law

In the wake of the global Coronavirus disease 2019 (COVID-19) pandemic, a rise in creditorinitiated winding-up proceedings is likely to be impending in coming years (See e.g., RCMA Asia Pte. Ltd. v. Sun Electric Power Pte. Ltd. [2020] SGHC 205). At the same time, geopolitical developments, such as the scale and ambition of Belt & Road Initiative projects, have raised questions over the issue of debt sustainability. Given the prevalence of arbitration clauses in modern international commercial and project agreements, the interplay and relationship between insolvency and dispute resolution, and especially arbitration, requires careful attention. While the intersections between the …

Much of the work that has been done in the first year has been focused on establishing a good …

An Improved Learnable Evolution Model For Solving Multi-Objective Vehicle Routing Problem With Stochastic Demand, Yunyun Niu, Detian Kong, Rong Wen, Zhiguang Cao, Jianhua Xiao

Research Collection School Of Computing and Information Systems

The multi-objective vehicle routing problem with stochastic demand (MO-VRPSD) is much harder to tackle than other traditional vehicle routing problems (VRPs), due to the uncertainty in customer demands and potentially conflicted objectives. In this paper, we present an improved multi-objective learnable evolution model (IMOLEM) to solve MO-VRPSD with three objectives of travel distance, driver remuneration and number of vehicles. In our method, a machine learning algorithm, i.e., decision tree, is exploited to help find and guide the desirable direction of evolution process. To cope with the key issue of "route failure" caused due to stochastic customer demands, we propose a …

Gp3: Gaussian Process Path Planning For Reliable Shortest Path In Transportation Networks, Hongliang Guo, Xuejie Hou, Zhiguang Cao, Jie Zhang

Research Collection School Of Computing and Information Systems

This paper investigates the reliable shortest path (RSP) problem in Gaussian process (GP) regulated transportation networks. Specifically, the RSP problem that we are targeting at is to minimize the (weighted) linear combination of mean and standard deviation of the path's travel time. With the reasonable assumption that the travel times of the underlying transportation network follow a multi-variate Gaussian distribution, we propose a Gaussian process path planning (GP3) algorithm to calculate the a priori optimal path as the RSP solution. With a series of equivalent RSP problem transformations, we are able to reach a polynomial time complexity algorithm with guaranteed …

On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle

Research Collection College of Integrative Studies

This paper explores popular expectations for and meanings of the U.S. West's environmental future, as articulated through recent artistic representations of the Los Angeles's expansive water provision network. Weaving together material from participant observation and readings of creative works, I show how infrastructural imagery is used to index anxieties about a future of water scarcity. Presenting familiar, currently functional water infrastructures as ruins-in-the-making, these artists use the physical stuff of water provision networks to advance critiques of longstanding modes of development and the material basis of urban-rural relations in the U.S. West. Doing so, these imagined ruins draw the global-scale …

Dynamic Lane Traffic Signal Control With Group Attention And Multi-Timescale Reinforcement Learning, Qize Jiang, Jingze Li, Weiwei Sun, Baihua Zheng

Research Collection School Of Computing and Information Systems

Traffic signal control has achieved significant success with the development of reinforcement learning. However, existing works mainly focus on intersections with normal lanes with fixed outgoing directions. It is noticed that some intersections actually implement dynamic lanes, in addition to normal lanes, to adjust the outgoing directions dynamically. Existing methods fail to coordinate the control of traffic signal and that of dynamic lanes effectively. In addition, they lack proper structures and learning algorithms to make full use of traffic flow prediction, which is essential to set the proper directions for dynamic lanes. Motivated by the ineffectiveness of existing approaches when …

A Critical Review On The Moderating Role Of Contextual Factors In The Associations Between Video Gaming And Well-Being, Andree Hartanto, Verity Yu Qing Lua, Frosch Yi Xuan Quek, Jose C. Yong, Matthew H. S. Ng

Research Collection School of Social Sciences

The appeal of video gaming has undoubtedly withstood the test of time. In view of its increasing popularity, lay people and researchers alike have taken an interest in the psychological consequences of video gaming. However, there seems to be a paradox associated with the effect of video gaming on gamers' well-being—namely, while most video game players cite “fun” as their motivation to play video games, video games continue to hold a notorious reputation among some researchers for being detrimental to mental health and emotional well-being as measured by indicators such as happiness, perceived stress, anxiety, and depressive symptoms. We suggest …

Missing Power: Nostalgia And Disillusionment Among Southern California Water Engineers, Sayd Randle

Research Collection College of Integrative Studies

California's sprawling network of aqueducts and dams is often cited as the embodiment of a high-modernist approach to resource management. But while once widely celebrated, in recent decades this infrastructural system and the institutions that manage it have been the subject of growing criticism and shrinking funding streams. Based on ethnographic research among employees at several California water agencies, this article explores the sense of nostalgia and diminished power experienced by the workers tasked with overseeing these networks. These emic perspectives are frequently articulated in the form of unfavorable comparisons to an imagined past, when the workers believe that their …

Dispositional Optimism As A Buffer Against Emotional Reactivity To Daily Stressors: A Daily Diary Approach, Nadyanna Majeed, Jacinth J. X. Tan, William Tov, Andree Hartanto

Research Collection School of Social Sciences

The current research examined if dispositional optimism buffers against the negative influences of daily stressors on affective experiences, using a daily diary study of two large and nationally-drawn samples of American adults (N = 2,349). Optimism, exposure to daily stressors, and daily positive and negative affect were assessed over eight days. Multilevel modelling revealed that optimism significantly attenuated the associations between daily stressor exposure and negative affect reactivity even after controlling for demographic factors, subjective physical health, and socioeconomic status. However, in a similar analysis, the inclusion of socioeconomic variables fully accounted for the moderating effect of optimism on stress …

Social Mindfulness And Prosociality Vary Across The Globe, Niels J. Van Doesum, Ryan O. Murphy, Marcello Gallucci, E. Aharonov-Majar, U. Athenstaedt, Wing Tung Au, Liying Bai, R. Bohm, I. Bovina, N.R. Buchan, Xiao-Ping Chen, K.B. Dumont, J.B. Englemann, ..., Li, Norman P.

Research Collection School of Social Sciences

Humans are social animals, but not everyone will be mindful of others to the same extent. Individual differences have been found, but would social mindfulness also be shaped by one's location in the world? Expecting cross-national differences to exist, we examined if and how social mindfulness differs across countries. At little to no material cost, social mindfulness typically entails small acts of attention or kindness. Even though fairly common, such low-cost cooperation has received little empirical attention. Measuring social mindfulness across 31 samples from industrialized countries and regions (n = 8,354), we found considerable variation. Among selected country-level variables, greater …

First Among Equals: The First Place Effect And Political Promotion In Multi-Member Plurality Elections, Dean C. Dulay, Laurence Go

Research Collection School of Social Sciences

We study the impact of rank-based decision-making in a multi-member plurality electoral system by examining the decisions of Philippine legislative councilors to run for and win higher office. By focusing on multi-member plurality elections, we identify the effect of rank amongst politicians that hold the same office and received a similar number of votes. To identify the causal effect of rank, we conduct a close-elections RD at the village, municipality, and province levels. Our main result is the first place effect: incumbent first placers are 5–9% (1–4%) more likely to run (win) in future elections than incumbent second placers. …

Media In A Time Of Crisis: Newspaper Coverage Of Covid-19 In East Asia;, Colm A. Fox

Research Collection School of Social Sciences

How have newspapers covered Covid-19 in Asia? To answer this question, I studied East Asian English-language newspapers published between January and July 2020. First, I measured the level of news media attention on Covid-19 among all reports. Second, I analyzed the tone and content of 330 editorials. I divided the analysis into two time periods: the initial crisis breakout period, when the number of infections was rising or high, and the crisis abatement period, when new infections declined to manageable levels. Findings show that although newspapers were slow to begin addressing the pandemic, their early editorials carried an alarming tone, …

Too Cynical To Reconnect: Cynicism Moderates The Effect Of Social Exclusion On Prosociality Through Empathy, Bryan K. C. Choy, Kimin Eom, Norman P. Li

Research Collection School of Social Sciences

Extant findings are mixed on whether social exclusion impacts prosociality. We propose one factor that may underlie the mixed results: Cynicism. Specifically, cynicism may moderate the exclusion-prosociality link by influencing interpersonal empathy. Compared to less cynical individuals, we expected highly cynical individuals who were excluded to experience less empathy and, consequently, less prosocial behavior. Using an online ball-tossing game, participants were randomly assigned to an exclusion or inclusion condition. Consistent with our predictions, the effect of social exclusion on prosociality through empathy was contingent on cynicism, such that only less-cynical individuals responded to exclusion with greater empathy, which, in turn, …

Efficient Estimation Of Integrated Volatility Functionals Under General Volatility Dynamics, Jia Li, Yunxiao Liu

Research Collection School Of Economics

We provide an asymptotic theory for the estimation of a general class of smooth nonlinear integrated volatility functionals. Such functionals are broadly useful for measuring financial risk and estimating economic models using high-frequency transaction data. The theory is valid under general volatility dynamics, which accommodates both Itô semimartingales (e.g., jump-diffusions) and long-memory processes (e.g., fractional Brownian motions). We establish the semiparametric efficiency bound under a nonstandard nonergodic setting with infill asymptotics, and show that the proposed estimator attains this efficiency bound. These results on efficient estimation are further extended to a setting with irregularly sampled data.

Discovery Of Mental Wellness Via Social Analytics For Liveability In An Urban City, Kar Way Tan

Research Collection School Of Computing and Information Systems

Smart cities, are often perceived as urban areas that use technologies to manage resources, improve economy and enhance community livelihood. In this paper, we share an approach which uses multiple sources of data for evidence-based analysis of the public's views, concerns and sentiments on the topic related to mental wellness. We hope to bring forth a better understanding of the existing concerns of the citizens and available social support. Our study leverages on social sensing via text mining and social network analysis to listen to the voices of the citizens through revealed content from web data sources, such as social …

Integrating Empirical Analysis Into Analytical Framework: An Integrated Model Structure For On-Demand Transportation, Yuliu Su, Ying Xu, Costas Courcoubetis, Shih-Fen Cheng

Research Collection School Of Computing and Information Systems

On-demand transportation services have been developing in an irresistible trend since their first launch in public. These services not only transform the urban mobility landscape, but also profoundly change individuals’ travel behavior. In this paper, we propose an integrated model structure which integrates empirical analysis into a discrete choice based analytical framework to investigate a heterogeneous population’s choices on ownership, usage and transportation mode with the presence of ride-hailing. Distinguished from traditional discrete choice models where individuals’ choices are only affected by exogenous variables and are independent of other individuals’ choices, our model extends to capture the endogeneity of supply …

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

Accounting And Finance Lessons In The Time Of Covid-19 – Views From The Pacific Basin, Kuan Yong David Ding, Julie Harrison, Martien Lubberink, Chris Van Staden

Research Collection Lee Kong Chian School Of Business

The COVID-19 pandemic is expected to create the worst economic recession in our lifetime and generate “enormous damage to our health, jobs, and well-being” (OECD, 2020). This special issue focuses on the lessons for accounting and finance policy-makers, practitioners, and academics as a result of the social and economic turmoil that arose in the immediate period following the World Health Organization’s declaration of a pandemic (WHO, 2020). Governments responded to support businesses and economies using various policy tools to support markets, businesses and individuals impacted by the pandemic. It is timely to consider the extent to which policymakers and standard-setters …

Public Sentiment Is Everything: Host-Country Public Sentiment Toward Home Country And Acquisition Ownership During Institutional Transition, Daphne W. Yiu, William P. Wan, Kelly Xing Chen, Xiaocong Tian

Research Collection Lee Kong Chian School Of Business

Under strict scrutiny of public governance primed by international relation tensions, geopolitics, and the rise of social movements and public activism in the globalized economy, public sentiment is exerting increasing pressure on multinational corporations (MNCs). Utilizing the context of inward acquisition, a sensitive cross-border action that often triggers sentiment of host-country nationals, we theorize from the public sentiment perspective and the public thermostat analogy that foreign acquirers will adjust their ownership levels in target firms according to how they perceive to be acceptable and legitimate as expressed by host-country nationals' public sentiment toward their home country. Using a sample of …

Public Cleanliness Satisfaction Survey 2021, Paulin Straughan, Mathews Mathew

Research Collection School of Social Sciences

The Singapore Management University undertook the fourth wave of the Public Cleanliness Satisfaction Survey (PCSS) with 2,007 Singapore resident respondents providing responses to the survey from February 2021 to May 2021, amidst the COVID-19 pandemic.

The 2021 wave of the PCSS continued to reflect the overall satisfaction with public cleanliness in Singapore, similar to the last PCSS in 2019. Majority of survey respondents (92%) were satisfied with the cleanliness of public spaces that they had recently visited, a 1% decrease from the findings in 2019.

There was a substantial drop in satisfaction with the cleanliness of food outlets, with a …

Psychology And The Threat Of Contagion: Feeling Vulnerable To A Disease Moderates The Link Between Xenophobic Thoughts And Support For Ingroup-Protective Actions, Heejung S. Kim, Kimin Eom, Roxie Chuang, David K. Sherman

Research Collection School of Social Sciences

The widespread threat of contagious disease disrupts not only everyday life but also psychological experience. Building on findings regarding xenophobic responses to contagious diseases, this research investigates how perceived vulnerability to a disease moderates the psychological link between people’s xenophobic thoughts and support for ingroup-protective actions. Three datasets collected during the time of Ebola (N = 867) and COVID-19 (Ns = 992 and 926) measured perceived disease risk, group-serving biases (i.e., xenophobic thoughts), and support for restrictive travel policies (i.e., ingroup-protective actions). Using correlational and quasi-experimental analyses, results indicated that for people who perceive greater disease risk, the association between …

Subjective Age And Inflammation Risk In Midlife Adults: Findings From The Midlife In The United States (Midus) Studies, Andree Hartanto, Nadyanna M. Majeed, Wee Qin Ng, Colin Kai Ning Chai, Verity Yu Qing Lua

Research Collection School of Social Sciences

Recent studies have suggested that subjective age—a subjective evaluation of one's own age—is a promising construct in gerontology that may contribute our understanding of risk for immune dysfunction. Nevertheless, studies documenting the association between subjective age and inflammatory biomarkers remain limited and provide mixed findings. In the present study, we revisited the relation between subjective age and systemic inflammation by utilizing a range of well-established inflammatory biomarkers (C-reactive protein, interleukin-6, fibrinogen, E-selectin, and intercellular adhesion molecule 1) through the collection of fasting blood samples before breakfast. In a large-scale dataset of midlife adults (N = 1800), we found some evidence …

Beyond The "Formidable Circle": Race And The Limits Of Democratic Inclusion In Tocqueville's Democracy In America, Christine Dunn Henderson

Research Collection School of Social Sciences

Despite his assertion that the first volume of Democracy in America (1835) would concentrate upon institutions, Tocqueville found himself finishing the draft manuscript in 1834 and unable to conclude his study without discussing race relations in the United States. In the end, he quickly penned a final chapter. That chapter—by far the book’s longest—offers “Some Considerations on the Present State and Probable Future of the Three Races That Inhabit the Territory of the United States.” Tocqueville begins the chapter by acknowledging that its subject “is American without being democratic” (DA, p. 516), and to the extent that it analyzes slavery …

How To Stop Procrastinating When Working From Home, Tina Li Yi Ng, Andree Hartanto
