Editorial Introduction: Re-Envisioning Education In A Globalizing World, Hiro Saito Dec 2019

Editorial Introduction: Re-Envisioning Education In A Globalizing World, Hiro Saito

Research Collection School of Social Sciences

This special issue focuses on education as a crucial factor mediating the relationship between youth and globalization. Specifically, four papers collectively explore how education can be re-envisioned from the following vantage point: the use of technology to foreground the fundamentally interconnected nature of today’s world; the help of mindfulness to deepen the awareness of such interconnectedness and cultivate acommitment to collective well-being; the role of activism to produce more critical knowledge and transformational solidarity for social justice on a global scale; at the same time, the necessity of reflexivity to examine one’s own ontological and epistemological assumptions before attempting any …

An Ai Approach To Measuring Financial Risk, Lining Yu, Wolfgang Karl Hardle, Lukas Borke, Thijs Benschop Dec 2019

An Ai Approach To Measuring Financial Risk, Lining Yu, Wolfgang Karl Hardle, Lukas Borke, Thijs Benschop

Sim Kee Boon Institute for Financial Economics

AI artificial intelligence brings about new quantitative techniques to assess the state of an economy. Here, we describe a new measure for systemic risk: the Financial Risk Meter (FRM). This measure is based on the penalization parameter (λ" role="presentation" style="box-sizing: border-box; display: inline; font-style: normal; font-weight: normal; line-height: normal; font-size: 18px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">λλ) of a linear quantile lasso regression. The FRM is calculated by taking the average …

The Unexpected Activeness Of Passive Investors: A Worldwide Analysis Of Etfs, Si Cheng, Massimo Massa, Hong Zhang Dec 2019

The Unexpected Activeness Of Passive Investors: A Worldwide Analysis Of Etfs, Si Cheng, Massimo Massa, Hong Zhang

Research Collection Lee Kong Chian School Of Business

The global ETF industry provides more complicated investment vehicles than low-cost index trackers. Instead, we find that the real investments of ETFs may deviate from their benchmarks to leverage informational advantages (which leads to a surprising stock-selection ability) and to help affiliated OEFs through cross-trading. These effects are more prevalent in ETFs domiciled in Europe. Moreover, ETF flows seem to respond to additional risk. These results have important normative implications for consumer protection and financial stability. (JEL G20)

The Future Development Of Reits In China, Jia Sun Dec 2019

The Future Development Of Reits In China, Jia Sun

Dissertations and Theses Collection (Open Access)

Real Estate Investment Trust (REIT) is a type of trust fund or corporation that pools the funds of a large number of investors by issuing a certificate of income and invest the raised funds in real estate projects that are managed by a specialized investment institution. The real estate investment risk is moderate, and the rent is stable, but the capital threshold is high, and it is difficult for small and medium investors to enter the market. The invention of REITs aims to solve this problem, through the collection of funds, so that small and medium investors can enter the …

Un Treaty On Mediation Signed In Singapore, Nadja Alexander, Shou Yu Chong Dec 2019

Un Treaty On Mediation Signed In Singapore, Nadja Alexander, Shou Yu Chong

Research Collection Yong Pung How School Of Law

The Singapore Convention on Mediation is a multilateral treaty which offers a legal framework facilitating the circulation of international mediated settlement agreements (iMSAs) across national borders. The Singapore Convention achieves this by elevating iMSAs to the status of a new type of legal instrument recognised in international law: neither a contract nor a consent arbitral award, iMSAs that fall within the scope of, and that satisfy the conditions within, the Singapore Convention enjoy a unique status. As outlined below, the new Convention establishes a system for the recognition and enforcement of commercial iMSAs. This report is a follow up to …

Singapore Case Note: Enforceability Of Settlement Agreements, Nadja Alexander, Shou Yu Chong Dec 2019

Singapore Case Note: Enforceability Of Settlement Agreements, Nadja Alexander, Shou Yu Chong

Research Collection Yong Pung How School Of Law

Since the signing of the Singapore Convention on Mediation in August this year, there has been an increased interest on the enforceability of settlement agreements, particularly those arising from mediation. The case of Law Chau Loon v Alphire Group Pte Ltd [2019] SGHC 275 from the Singapore High Court provides us with some general legal principles to consider when a settlement agreement is drafted. Although mediation did not take place between the parties in dispute, the principles stated by the High Court here remain relevant to the drafting of binding mediated settlement agreements (MSAs). This case is essential reading for …

Politics And Policy: Chinese Money And Its Impact On The Regulation Of Residential Property In The West, Edward Seng Wei Ti Dec 2019

Politics And Policy: Chinese Money And Its Impact On The Regulation Of Residential Property In The West, Edward Seng Wei Ti

Research Collection Yong Pung How School Of Law

The narrative of Chinese real estate investors in some western jurisdictions reads like this: China has in recent decades, enjoyed burgeoning wealth creation across all strata in society. Chinese buyers are attracted to a ‘westernised’ education for their children, an agreeable and law-abiding civic society all whilst living in a clean and pleasant environment. Western real estate markets are seen as safe havens and bringing about portfolio diversification. This flood of Chinese wealth has impacted residential housing markets resulting in locals being outpriced. To combat unaffordability and housing shortages, governments have had no choice but to impose regulatory measures preventing …

The Role Of Career And Wage Incentives In Labor Productivity: Evidence From A Two-Stage Field Experiment In Malawi, Hyuncheol Kim, Seonghoon Kim, Thomas Kim Dec 2019

The Role Of Career And Wage Incentives In Labor Productivity: Evidence From A Two-Stage Field Experiment In Malawi, Hyuncheol Kim, Seonghoon Kim, Thomas Kim

Research Collection School Of Economics

We study how career and wage incentives affect labor productivity through self-selection and incentive effect channels using a two-stage field experiment in Malawi. First, recent secondary school graduates were hired with either career or wage incentives. After employment, a half of workers with career incentives randomly received wage incentives, and a half of workers with wage incentives randomly received career incentives. Career incentives attract higher-performing workers than wage incentives, but do not increase productivity conditional on selection. Wage incentives increase productivity for those recruited through career incentives. Observable characteristics are limited in explaining selection effects of entry-level workers.

Growth Effects Of Additive And Multiplicative Robots Alongside Conventional Machines, Hian Teck Hoon Dec 2019

Growth Effects Of Additive And Multiplicative Robots Alongside Conventional Machines, Hian Teck Hoon

Research Collection School Of Economics

We study the effects of introducing two different types of robots (additive and multiplicative) in an infinitely lived one-sector aggregative model with malleable capital on wages. The wage effects of these two polar cases are dramatically different. Given malleable capital that can be retrofitted for use either as conventional machines or as robots, we show that when it is profitable for firms to adopt additive robots in the production process, the real wage drops on impact and remains permanently at the lower level even as total malleable capital accumulates. However, when multiplicative robots are adopted, we show that while the …

Do Real Estate Agents Have Information Advantages In Housing Markets?, Sumit Agarwal, Jia He, Tien Foo Sing, Changcheng Song Dec 2019

Do Real Estate Agents Have Information Advantages In Housing Markets?, Sumit Agarwal, Jia He, Tien Foo Sing, Changcheng Song

Research Collection Lee Kong Chian School Of Business

We use a large housing transaction data set in Singapore to study whether real estate agents use information advantages to buy houses at bargain prices. Agents bought their own houses at prices that are 2.54% lower than comparable houses bought by other buyers. Consistent with information asymmetries, agent buyers have more information advantages in less informative environments, and agent buyers are more likely to buy houses from agent sellers. Agent discounts are from both “cherry picking” and bargaining power, and bargaining power contributes more to the agent discounts. Agents’ advantage consists in their information of available houses and previous purchase …

Climbing The Corporate Ladder And Within-Person Changes In Narcissism: Reciprocal Relationships Over Two Decades, Bart Wille, Joeri Hofmans, Filip Lievens, Mitja D. Back, Filip De Fruyt Dec 2019

Climbing The Corporate Ladder And Within-Person Changes In Narcissism: Reciprocal Relationships Over Two Decades, Bart Wille, Joeri Hofmans, Filip Lievens, Mitja D. Back, Filip De Fruyt

Research Collection Lee Kong Chian School Of Business

Prior research demonstrated that narcissism fosters the attainment of higher managerial ranks in organizations. However, it is not known whether climbing the corporate ladder also fosters the development of narcissism over time. Whereas prior work consistently adopted a unidirectional perspective on narcissism and career attainment, this study presents and tests a bidirectional perspective, incorporating long-term development in narcissism in relation to and in response to long-term upward mobility. To this end, a cohort of highly educated professionals was assessed three times over a 22-year time frame. Extended latent difference score modeling showed that, over the entire interval, within-person changes in …

Study Group Travel Behaviour Patterns From Large-Scale Smart Card Data, Xiancai Tian, Baihua Zheng Dec 2019

Study Group Travel Behaviour Patterns From Large-Scale Smart Card Data, Xiancai Tian, Baihua Zheng

Research Collection School Of Computing and Information Systems

In this paper, we aim at studying the group travel behaviour (GTB) patterns from large-scale auto fare collection (AFC) data. GTB is defined as two or more commuters intentionally and regularly traveling together from an origin to a destination. We propose a method to identify GTB accurately and efficiently and apply our method to the Singapore AFC dataset to reveal the GTB patterns of Singapore commuters. The case study proves that our method is able to identify GTB patterns more accurately and efficiently than the state-of-the-art.

Tuning Networks For Prosocial Behavior: From Senseless Swarms To Smart Mobs [Commentary], Sun Sun Lim, Roland Bouffanais Dec 2019

Tuning Networks For Prosocial Behavior: From Senseless Swarms To Smart Mobs [Commentary], Sun Sun Lim, Roland Bouffanais

Research Collection College of Integrative Studies

Social media have been seen to accelerate the spread of negative content such as disinformation and hate speech, often unleashing a reckless herd mentality within networks, further aggravated by malicious entities using bots for amplification. So far, the response to this emerging global crisis has centered around social media platform companies making reactive moves that appear to have greater symbolic value than practical utility. Proposes a solution to favor prosocial behavior via social networks.

Sieve Estimation Of Time-Varying Panel Data Models With Latent Structures, Liangjun Su, Xia Wang, Sainan Jin Dec 2019

Sieve Estimation Of Time-Varying Panel Data Models With Latent Structures, Liangjun Su, Xia Wang, Sainan Jin

Research Collection School Of Economics

We propose a heterogeneous time-varying panel data model with a latent group structure that allows the coefficients to vary over both individuals and time. We assume that the coefficients change smoothly over time and form different unobserved groups. When treated as smooth functions of time, the individual functional coefficients are heterogeneous across groups but homogeneous within a group. We propose a penalized-sieve-estimation-based classifier-Lasso (C-Lasso) procedure to identify the individuals’ membership and to estimate the group-specific functional coefficients in a single step. The classification exhibits the desirable property of uniform consistency. The C-Lasso estimators and their post-Lasso versions achieve the oracle …

Detecting Financial Collapse And Ballooning Sovereign Risk, Peter C. B. Phillips, Sp Shi Dec 2019

Detecting Financial Collapse And Ballooning Sovereign Risk, Peter C. B. Phillips, Sp Shi

Research Collection School Of Economics

This paper proposes a new model for capturing discontinuities in the underlying financial environment that can lead to abrupt falls, but not necessarily sustained monotonic falls, in asset prices. This notion of price dynamics is consistent with existing understanding of market crashes, which allows for a mix of market responses that are not universally negative. The model may be interpreted as a martingale composed with a randomized drift process that is designed to capture various asymmetric drivers of market sentiment. In particular, the model is capable of generating realistic patterns of price meltdowns and bond yield inflations that constitute major …

Individual Differences In Executive Function And Reappraisal: A Latent-Variable Analysis, Wei Xing Toh Dec 2019

Individual Differences In Executive Function And Reappraisal: A Latent-Variable Analysis, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Cognitive reappraisal is an adaptive emotion regulation strategy that positively impacts various facets of adaptive functioning (e.g., interpersonal relations, subjective well-being). Although reappraisal implicates cognitive processing, a clear consensus concerning the cognitive underpinnings of reappraisal has not yet been reached. Therefore, we examined how executive function (EF)—i.e., three general-purpose control abilities comprising working memory, inhibition, and shifting—are associated with performance-based reappraisal ability and self-reported reappraisal frequency. Using a latent-variable approach, we found that the shared variance among EF tasks (i.e., common EF)—a general goal-management ability that facilitates the active maintenance of task goals—significantly predicted reappraisal ability, but not reappraisal frequency. …

Of Promoting Networking And Protecting Privacy: Effects Of Defaults And Regulatory Focus On Social Media Users’ Preference Settings, Hichang Cho, Sungjong Roh, Byungho Park Dec 2019

Of Promoting Networking And Protecting Privacy: Effects Of Defaults And Regulatory Focus On Social Media Users’ Preference Settings, Hichang Cho, Sungjong Roh, Byungho Park

Research Collection Lee Kong Chian School Of Business

Privacy research has debated whether privacy decision-making is determined by users' stable preferences (i.e., individual traits), privacy calculus (i.e., cost-benefit analysis), or “responses on the spot” that vary across contexts. This study focuses on two factors—default setting as a contextual factor and regulatory focus as an individual difference factor—and examines the degree to which these factors affect social media users' decision-making when using privacy preference settings in a fictitious social networking site. The results, based on two experimental studies (study 1, n = 414; study 2, n = 213), show that default settings significantly affect users' privacy preferences, such that …

Unlocking Pre-1850 Instrumental Meteorological Records: A Global Inventory, Stefan Bronnimann, Rob Allan, Linden Ashcroft, Saba Baer, Mariano Barriendos, Fiona Williamson, Et Al Dec 2019

Unlocking Pre-1850 Instrumental Meteorological Records: A Global Inventory, Stefan Bronnimann, Rob Allan, Linden Ashcroft, Saba Baer, Mariano Barriendos, Fiona Williamson, Et Al

Research Collection School of Social Sciences

A global inventory of early instrumental meteorological measurements is compiled. It comprises thousands of series, many of which have not been digitized, pointing to the potential of weather data rescue.Instrumental meteorological measurements from periods prior to the start of national weather services are designated “early instrumental data”. They have played an important role in climate research as they allow daily-to-decadal variability and changes of temperature, pressure, and precipitation, including extremes, to be addressed. Early instrumental data can also help place 21st century climatic changes into a historical context such as to define pre-industrial climate and its variability. Until recently, the …

Research Collection School of Social Sciences

The strength of sexual selection on secondary sexual traits varies depending on prevailing economic and ecological conditions. In humans, cross-cultural evidence suggests women’s preferences for men’s testosterone dependent masculine facial traits are stronger under conditions where health is compromised, male mortality rates are higher and economic development is higher. Here we use a sample of 4483 exclusively heterosexual women from 34 countries and employ mixed effects modelling to test how social, ecological and economic variables predict women’s facial masculinity preferences. We report women’s preferences for more masculine looking men are stronger in countries with higher sociosexuality and where national health …

“Daughter” As A Positionality And The Gendered Politics Of Taking Parents Into The Field, Menusha De Silva, Kanchan Gandhi Dec 2019

“Daughter” As A Positionality And The Gendered Politics Of Taking Parents Into The Field, Menusha De Silva, Kanchan Gandhi

Research Collection School of Social Sciences

Research on gendered politics of the field has delved into the practices of accompaniment and its implications on research and knowledge production, particularly through the case of researchers’ children and partners. In comparison, the tendency to seek assistance from parents is neglected within the scholarship. Drawing on the PhD fieldwork experiences of two researchers in their “native” country, specifically a Sri Lankan researcher conducting fieldwork in Sri Lanka and a North Indian scholar researching in South India, the paper reveals parents’ contribution to the research process, in terms of enhancing researcher credibility, facilitating contact‐making and access, and providing emotional and …

Har Testing For Spurious Regression In Trend, Peter C. B. Phillips, Xiaohu Wang, Yonghui Zhang Dec 2019

Har Testing For Spurious Regression In Trend, Peter C. B. Phillips, Xiaohu Wang, Yonghui Zhang

Research Collection School Of Economics

The usual t test, the t test based on heteroskedasticity and autocorrelation consistent (HAC) covariance matrix estimators, and the heteroskedasticity and autocorrelation robust (HAR) test are three statistics that are widely used in applied econometric work. The use of these significance tests in trend regression is of particular interest given the potential for spurious relationships in trend formulations. Following a longstanding tradition in the spurious regression literature, this paper investigates the asymptotic and finite sample properties of these test statistics in several spurious regression contexts, including regression of stochastic trends on time polynomials and regressions among independent random walks. Concordant …

Uniform Inference In Panel Autoregression, John C. Chao, Peter C. B. Phillips Dec 2019

Uniform Inference In Panel Autoregression, John C. Chao, Peter C. B. Phillips

Research Collection School Of Economics

This paper considers estimation and inference concerning the autoregressive coefficient (rho) in a panel autoregression for which the degree of persistence in the time dimension is unknown. Our main objective is to construct confidence intervals for rho that are asymptotically valid, having asymptotic coverage probability at least that of the nominal level uniformly over the parameter space. The starting point for our confidence procedure is the estimating equation of the Anderson-Hsiao (AH) IV procedure. It is well known that the AH IV estimation suffers from weak instrumentation when rho is near unity. But it is not so well known that …

What’S Love Got To Do With It?: Passion And Inequality At Work, Aliya Hamid Rao, Megan Tobias Neely Dec 2019

What’S Love Got To Do With It?: Passion And Inequality At Work, Aliya Hamid Rao, Megan Tobias Neely

Research Collection School of Social Sciences

Emotion has become an increasingly important aspect of work in the 21st century. In this article, we take stock of the extant literature delineating the role of emotions, especially passion as a cultural schema, in white‐collar workplaces. Scholars have covered extensive ground on emotions at work, but the role of passion remains an underexplored yet significant area. Drawing from recent developments in research on white‐collar work, we argue that the passion schema has become a critical marker in the labor market for sorting individuals into occupations, hiring and promotion within organizations, and assigning value to people's labor. Emergent research suggests …

Imaginary Conquests: Folktales, Film, And The Japanese Empire In Asia, Richard M Davis Dec 2019

Imaginary Conquests: Folktales, Film, And The Japanese Empire In Asia, Richard M Davis

Research Collection School of Social Sciences

This article highlights three family-targeted films made under the wartime Japanese empire: Yamamoto Kajir ō ’s musical comedy Songokū (1940) and Seo Mitsuyo’s animated Momotarō films, Sea Eagles (1943) and Divine Warriors of the Sea (1945). Significantly, these films are based on two fantastical premodern stories—the Chinese novel Journey to the West and the Japanese Momotarō legend, respectively—whose quest narratives map onto Japan’s contemporaneous military expansion into mainland China and the islands of the South Pacific. Despite the films’ seeming alignment with ultranationalist ideology, I argue that the geopolitical trajectories of their narratives are rendered ambiguous by their various reception …

The contribution examines critical developments of the Chinese (Taiwan) Yearbook of International Law and Affairs and its contribution to the ‘Grotian moment’ in Asia. The Yearbook is the first publication specialized in international law in Greater China, a Chinese-speaking region that includes Mainland China, Taiwan, Hong Kong and Macau. The founding of the Yearbook in 1981 was a response to the unique status of the Republic of China (ROC) rendered after its loss of representation in the United Nations under General Assembly Resolution 2758 of 1971. Over the past 40 years, the Yearbook has become an intellectual depository of research …

Optimal Control For Transboundary Pollution Under Ecological Compensation: A Stochastic Differential Game Approach, Ke Jiang, Ryan Knowles Merrill, Daming You, Pan Pan Dec 2019

Optimal Control For Transboundary Pollution Under Ecological Compensation: A Stochastic Differential Game Approach, Ke Jiang, Ryan Knowles Merrill, Daming You, Pan Pan

Research Collection Lee Kong Chian School Of Business

To account for previously ignored, yet widely observed uncertainty in nature's capability to replenish the natural environment in ways that should inform ideal design of ecological compensation (EC) regimes, this study constructs a stochastic differential game (SDG) model to analyze transboundary pollution control options between a compensating and compensated region. Equilibrium strategies in the stochastic, two player game inform optimal control theory and reveal a welfare distribution mechanism to form the basis of an improved cooperative game contract. A case-based numerical example serves to verify the theoretical results and supports three key insights. First, accounting for various random disturbance factors, …

For Ye Have The Poor Always With You: Exploring China's Latest War On Poverty, John A. Donaldson Dec 2019

For Ye Have The Poor Always With You: Exploring China's Latest War On Poverty, John A. Donaldson

Research Collection School of Social Sciences

John Donaldson’s section discusses Xi Jinping’s ambitious pledge to end poverty in China by 2020, toward which the CCP has deployed a locally adaptable set of policies that have mobilized actors in the public and private sectors and tied officials’ performance to success in poverty reduction. The Party understands that poverty—a manifestation of a severe inability to provide a good life for the people—represents a concerning indictment of the regime’s legitimacy overall. This paper fills in an analytic gap among Western sources regarding these programs, which have to date seen well over fifty billion dollars of poverty alleviation funding disbursed …

Appmod: Helping Older Adults Manage Mobile Security With Online Social Help, Zhiyuan Wan, Lingfeng Bao, Debin Gao, Eran Toch, Xin Xia, Tamir Mendel, David Lo

Research Collection School Of Computing and Information Systems

The rapid adoption of Smartphone devices has caused increasing security and privacy risks and breaches. Catching up with ever-evolving contemporary smartphone technology challenges leads older adults (aged 50+) to reduce or to abandon their use of mobile technology. To tackle this problem, we present AppMoD, a community-based approach that allows delegation of security and privacy decisions a trusted social connection, such as a family member or a close friend. The trusted social connection can assist in the appropriate decision or make it on behalf of the user. We implement the approach as an Android app and describe the results of …

Long-Term Index Fund Ownership And Stock Returns, Ekkehart Boehmer, Wanshan Song, Ashish Tiwari, Zhe Zhang Dec 2019

Long-Term Index Fund Ownership And Stock Returns, Ekkehart Boehmer, Wanshan Song, Ashish Tiwari, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

We examine the implications of stock ownership by index funds for shareholder value. Consistent with recent findings that stock ownership by passive funds contributes to improved governance, we document a strong positive relation between the duration of passive fund holdings and subsequent stock performance. This positive relation is more pronounced for firms with recent poor performance, and for smaller firms and firms with higher allocation weights in passive funds’ portfolios. Our results support the view that index funds, although passive in their investment decisions, successfully contribute to long-term value creation by actively engaging with firms on matters of governance.
