Social Media Influencers And Instagram Storytelling: Case Study Of Singapore Instagram Influencers, Mark Chong, Gottipati Swapna Dec 2020

Social Media Influencers And Instagram Storytelling: Case Study Of Singapore Instagram Influencers, Mark Chong, Gottipati Swapna

Research Collection Lee Kong Chian School Of Business

While the use of social media influencers (SMIs) by brands is becoming more widespread, the academic literature about SMI communication is still scarce. This is one of the first studies on SMI brand storytelling, using data mining and natural language processing to understand how SMIs tell brand stories on Instagram, what kinds of stories they tell, and the impact they have on follower engagement. The findings show that the "rise-fall" emotional arc was the most common story arc used by SMIs. In addition, SMIs frequently used the first-person perspective and featured themselves as the protagonists in their stories. Last, SMIs …

A negotiation expert and a compensation geek came together to answer some of the toughest salary negotiation questions from the Master of Human Capital Leadership (MHCL) 2020 graduate cohort. We hope that our combined experiences in this field would help shed some light on the complex world of salary negotiations.


The Convergence Of Water, Electricity And Gas Industries: Implications For Ppp Design And Regulation, Sock Yong Phang Dec 2020

The Convergence Of Water, Electricity And Gas Industries: Implications For Ppp Design And Regulation, Sock Yong Phang

Research Collection School Of Economics

In several countries that have privatised their utilities, power and water are separate industries regulated by sector-specific regulators. In a parallel development, desalination has become an important source of water supply in countries where there is a shortage of cheap and clean freshwater. Where the energy source is gas, the use of gas-fired power plants to supply electricity for desalination links the water, electricity and gas industries. We use the case of the financial collapse of an integrated water and power project to illustrate the problems that can arise from such convergence, and to draw lessons for firms, Public-Private Partnerships …


Business Practice Of Social Media - Platform And Customer Service Adoption, Shujing Sun, Yang Gao, Huaxia Rui Dec 2020

Business Practice Of Social Media - Platform And Customer Service Adoption, Shujing Sun, Yang Gao, Huaxia Rui

Research Collection School Of Computing and Information Systems

This paper examines the key drivers in business adoptions of the platform and customer service within the context of social media. We carry out the empirical analyses using the decision trajectories of the international airline industry on Twitter. We find that a firm's decision-making is subject to both peer influence and consumer pressure. Regarding peer influence, we find that the odds of both adoptions increase when the extent of peers' adoption increases. We also identify the distinctive role of consumers. Specifically, before the platform adoption, firms learn about potential consequences from consumer reactions to peers' adoptions. Upon the platform adoption, …


Prediction Of Nocturia In Live Alone Elderly Using Unobtrusive In-Home Sensors, Barry Nuqoba, Hwee-Pink Tan Dec 2020

Prediction Of Nocturia In Live Alone Elderly Using Unobtrusive In-Home Sensors, Barry Nuqoba, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

Nocturia, or the need to void (or urinate) one or more times in the middle of night time sleeping, represents a significant economic burden for individuals and healthcare systems. Although it can be diagnosed in the hospital, most people tend to regard nocturia as a usual event, resulting in underreported diagnosis and treatment. Data from self-reporting via a voiding diary may be irregular and subjective especially among the elderly due to memory problems. This study aims to detect the presence of nocturia through passive in-home monitoring to inform intervention (e.g., seeking diagnosis and treatment) to improve the physical and mental …


The Future Is Urban: The Progressive Renaissance Of The City In Eu Law, De Maartje Visser Dec 2020

The Future Is Urban: The Progressive Renaissance Of The City In Eu Law, De Maartje Visser

Research Collection Yong Pung How School Of Law

For much of the European integration process, local authorities have been on the legal margins. Yet many amongst this group, and cities in particular, consider themselves as important players in realising the Union’s overarching policy objectives. This view is slowly but surely fi nding traction with the EU’s political institutions. This article suggests that the future architecture of the European Union’s (EU’s) operating system will evince a rapprochement between the socio-economic clout of local authorities, notably cities, and their legal-political recognition at Union level. It further suggests that there is room for greater conceptual clarity along two lines when interrogating …


Trusts And Jurisdiction Clauses - Crociani Revisited: Ivanishvili, Bidzina And Others V Credit Suisse Trust Ltd [2020] Sgca 62, Kian Peng Soh Dec 2020

Trusts And Jurisdiction Clauses - Crociani Revisited: Ivanishvili, Bidzina And Others V Credit Suisse Trust Ltd [2020] Sgca 62, Kian Peng Soh

Research Collection Yong Pung How School Of Law

In the recent Singapore Court of Appeal decision of Ivanishvili, Bidzina and others v Credit Suisse Trust Ltd, the court analysed the effect of a forum administration clause in the trust context, holding that while the clause in question was a jurisdiction clause, it was not an exclusive jurisdiction clause governing the dispute between the trustees and beneficiaries.


Local Dominance, Emiliano Catonini, Jingyi Xue Dec 2020

Local Dominance, Emiliano Catonini, Jingyi Xue

SMU Economics and Statistics Working Paper Series

We define a local notion of weak dominance that speaks to the true choice problems among actions in a game tree and does not necessarily require to plan optimally for the future. A strategy is (globally) weakly dominant if and only if it prescribes a locally weakly dominant action at every decision node it reaches, and in this case local weak dominance is characterized by a (wishful-thinking) condition that requires no forward planning. From this local perspective, we identify form of contingent reasoning that are particularly natural, despite the absence of an obviously dominant strategy (Li, 2017). Following this approach, …


Decomposing Duration Dependence: Skill Depreciation Vs. Statistical Discrimination, Ismail Baydur, Jianhuan Xu Dec 2020

Decomposing Duration Dependence: Skill Depreciation Vs. Statistical Discrimination, Ismail Baydur, Jianhuan Xu

Research Collection School Of Economics

This paper develops a random matching model with unobserved worker heterogeneity and learning about worker types from unemployment duration. The model features negative duration dependence that stems from unobserved heterogeneity as well as statistical discrimination and skill depreciation. We estimate our model using micro-level data from Current Population Survey (CPS) and we decompose the contribution of each channel to job finding rates by duration. We find that shutting down statistical discrimination substantially increases the job finding rates of the long-term unemployed while skill depreciation mainly affects the medium-term unemployed.


International Tax Competition And Foreign Direct Investment In The Asia-Pacific Region: A Panel Data Analysis, Chengwei Xu, Alfred M. Wu Dec 2020

International Tax Competition And Foreign Direct Investment In The Asia-Pacific Region: A Panel Data Analysis, Chengwei Xu, Alfred M. Wu

Research Collection School Of Accountancy

Purpose: The purpose of this study is to investigate how a country's competitive tax policy influences its inward foreign direct investments (FDI) in the Asia–Pacific region, even when given particular constraints (e.g., population, public governance, skilled labor, and so on) exist. Design/methodology/approach: The paper uses the system GMM estimation approach to test the hypothesis. Data on FDI, corporate income tax, and various confounding factors were drawn from Ernst and Young's worldwide corporate tax guide, the World Bank, and other sources to create a panel of 28 economies over the period 2000–2016. Findings: The present research confirms the negative association between …


Mediating Consumer Financial Disputes: Financial Industry Disputes Resolution Centre's Unique House Style, Eunice Chua, Beverly Wee Dec 2020

Mediating Consumer Financial Disputes: Financial Industry Disputes Resolution Centre's Unique House Style, Eunice Chua, Beverly Wee

Research Collection Yong Pung How School Of Law

The Financial Industry Disputes Resolution Centre (“FIDReC”) was established in August 2005 with the purpose of providing a low-cost avenue for consumers to resolve their disputes with financial institutions. This article seeks to outline the role of FIDReC and its processes and, at the same time, seeks to define the house style of mediation that has served FIDReC well over the years. This article also highlights some of the different techniques adopted by FIDReC mediators in the course of facilitating the mediation.


What's On Job Seekers' Social Media Sites? A Content Analysis And Effects Of Structure On Recruiter Judgments And Predictive Validity, Liwen Zhang, Chad H. Van Iddekinge, John D. Arnold, Philip L. Roth, Filip Lievens, Stephen E. Lanivich, Samantha L. Jordan Dec 2020

What's On Job Seekers' Social Media Sites? A Content Analysis And Effects Of Structure On Recruiter Judgments And Predictive Validity, Liwen Zhang, Chad H. Van Iddekinge, John D. Arnold, Philip L. Roth, Filip Lievens, Stephen E. Lanivich, Samantha L. Jordan

Research Collection Lee Kong Chian School Of Business

Many organizational representatives review social media (SM) information (e.g., Facebook, Twitter) when recruiting and assessing job applicants. Despite this, very little empirical data exist concerning the SM information available to organizations or whether assessments of such information are a valid predictor of work outcomes. This multi-study investigation examines several critical issues in this emerging area. In Study 1, we conducted a content analysis of job seekers’ Facebook sites (n = 266) and found that these sites often provide demographic variables that U.S. employment laws typically prohibit organizations from using when making personnel decisions (e.g., age, ethnicity, religion), as well as …


Natural Disasters And Domestic Violence: A Study Of The 2015 Nepal Earthquake, Arpita Khanna, Tomoki Fujii Dec 2020

Natural Disasters And Domestic Violence: A Study Of The 2015 Nepal Earthquake, Arpita Khanna, Tomoki Fujii

Research Collection School Of Economics

This study explores the link between exposure to an earthquake and the incidence of intimate partner violence using two rounds of Demographic and Health Surveys data in Nepal. Using a differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in the incidence of intimate partner violence in urban areas, which is attributable to the increase in stress felt by the victims. We argue that the heterogeneity of the impact between the urban and rural areas would be partly due to the differences in the reconstruction processes and assistance provided.


End-User Perceptions Of Success And Failure: Narratives From A Natural Laboratory Of Rural Electrification Projects In Malaysian Borneo, Terry Van Gevelt, T. Zaman, F. George, M.M Bennett, S.D. Fam, J.E. Kim Dec 2020

End-User Perceptions Of Success And Failure: Narratives From A Natural Laboratory Of Rural Electrification Projects In Malaysian Borneo, Terry Van Gevelt, T. Zaman, F. George, M.M Bennett, S.D. Fam, J.E. Kim

Research Collection College of Integrative Studies

Located deep in the Kelabit Highlands in Malaysian Borneo, the remote town of Bario offers us a natural laboratory of rural electrification projects through which to understand end-user perceptions of success and failure, and the factors that contribute to these perceptions. We use a case-study based approach and focus on three off-grid energy projects: a 110 kW mini-hydro power plant; a 12 kW wind turbine system; and a 1.59 MW solar-diesel hybrid system. We find that end-users primarily see the success or failure of a project in technical terms, but that this narrow conceptualization masks important interactions between technical, economic …


Point Optimal Testing With Roots That Are Functionally Local To Unity, Anna Bykhovskaya, Peter C. B. Phillips Dec 2020

Point Optimal Testing With Roots That Are Functionally Local To Unity, Anna Bykhovskaya, Peter C. B. Phillips

Research Collection School Of Economics

Limit theory for regressions involving local to unit roots (LURs) is now used extensively in time series econometric work, establishing power properties for unit root and cointegration tests, assisting the construction of uniform confidence intervals for autoregressive coefficients, and enabling the development of methods robust to departures from unit roots. The present paper shows how to generalize LUR asymptotics to cases where the localized departure from unity is a time varying function rather than a constant. Such a functional local unit root (FLUR) model has much greater generality and encompasses many cases of additional interest that appear in practical work, …


Causal Change Detection In Possibly Integrated Systems: Revisiting The Money-Income Relationship, Shuping Shi, Stan Hurn, Peter C. B. Phillips Dec 2020

Causal Change Detection In Possibly Integrated Systems: Revisiting The Money-Income Relationship, Shuping Shi, Stan Hurn, Peter C. B. Phillips

Research Collection School Of Economics

This paper re-examines changes in the causal link between money and income in the United States over the past half century (1959-2014). Three methods for the data-driven discovery of change points in causal relationships are proposed, all of which can be implemented without prior detrending of the data. These methods are a forward recursive algorithm, a rolling window algorithm, and a recursive evolving algorithm all of which utilize subsample tests of Granger causality within a lagaugmented vector autoregressive framework. The limit distributions for these subsample Wald tests are provided. Bootstrap methods are developed to control family-wise size in the implementation …


Asymptotic Properties Of Least Squares Estimator In Local To Unity Processes With Fractional Gaussian Noises, Xiaohu Wang, Weilin Xiao, Jun Yu Dec 2020

Asymptotic Properties Of Least Squares Estimator In Local To Unity Processes With Fractional Gaussian Noises, Xiaohu Wang, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper derives asymptotic properties of the least squares estimator of the autoregressive parameter in local to unity processes with errors being fractional Gaussian noises with the Hurst parameter H. It is shown that the estimator is consistent when H ∈ (0, 1). Moreover, the rate of convergence is n when H ∈ [0.5, 1). The rate of convergence is n2H when H ∈ (0, 0.5). Furthermore, the limit distribution of the centered least squares estimator depends on H. When H = 0.5, the limit distribution is the same as that obtained in Phillips (1987a) for the local to …


On Strategy-Proofness And The Salience Of Single-Peakedness In A Private Goods Economy, Shurojit Chatterji, Masso Jordi, Serizawa Shigehiro Dec 2020

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

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 where preferences display satiation. We show that if the rule is in addition "desirable", in that it is tops-only, continuous, 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 smilattice single-peakedness). We also provide a converse of this main finding. It turns our that this domain coincides with the one already identified in …


Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang Dec 2020

Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang

Research Collection School Of Economics

This paper studies how the trade liberalization in China changes the firm productivity. We develop a framework to estimate revenue productivity (TFPR) and real productivity (TFPQ) with multi-product firms. We find that the aggregate TFPR increases 30\% from 2002-2007 and TFPQ increases 22\%, suggesting that the observed TFPR increase is mainly driven by real productivity change rather than the markup change. We further decompose the change of productivity into three channels: (1) access to foreign inputs; (2) technology upgrade; (3) resource re-allocation within the firm. We find the most significant channel is the last one, which explains half of the …


Density Of Demand And The Consumer Benefit From Uber, Matthew H. Shapiro Dec 2020

Density Of Demand And The Consumer Benefit From Uber, Matthew H. Shapiro

Research Collection School Of Economics

Uber has attracted the attention of economists and policy makers for its innovations in the taxicab market and its potential for significant consumer welfare gains. The size of this gain depends in part on whether these innovations permit transactions previously costly or infeasible. Using New York City — the largest taxi market in the country — as its context, this paper estimates the level of any technological advantage Uber has over hail taxis in matching to consumers. I combine publicly available transportation data with data scraped from Uber and traffic cameras to estimate a model of the demand for transportation …


Motivation Purity Bias: Expression Of Extrinsic Motivation Undermines Perceived Intrinsic Motivation And Engenders Bias In Selection Decisions, Rellie Derfler-Rozin, Marko Pitesa Dec 2020

Motivation Purity Bias: Expression Of Extrinsic Motivation Undermines Perceived Intrinsic Motivation And Engenders Bias In Selection Decisions, Rellie Derfler-Rozin, Marko Pitesa

Research Collection Lee Kong Chian School Of Business

Organizational selection decisions often involve an exchange of information between candidates and decision makers as to why candidates are motivated to work in the given position. Drawing on popular management myths as our overarching framework, we theorize that candidates’ expressions of extrinsic motivation lead decision makers to infer that the candidate is less intrinsically motivated, leading to bias against such candidates. We term this effect motivation purity bias, and argue that it emerges despite ample evidence, which we review, showing that penalizing expressed extrinsic motivation is not only unfair to candidates but also counterproductive from the standpoint of maximizing future …


Public Relations Education In Singapore: Educating The Next Generation Of Practitioners On Ethics, Eugene Yong Sheng Woon, Augustine Pang Dec 2020

Public Relations Education In Singapore: Educating The Next Generation Of Practitioners On Ethics, Eugene Yong Sheng Woon, Augustine Pang

Research Collection Lee Kong Chian School Of Business

This study examines if PR education adequately prepares students for the workplace, particularly in the practice of ethics in the context of Singapore, which has been described as one of “Asia’s economic tigers” (BBC, 2018). This study, thus, aims to first, elucidate the state of PR education specifically in relation to how PR ethics is taught in Singapore. Second, it examines how ethics education prepares students for the workplace in Singapore. Data comes from examining the syllabi of 14 universities in Singapore, both local and international, and interviews with 20 academics and practitioners. Findings suggest there are varying degrees in …


A Two-Stage Parallel Network Dea Model For Analyzing The Operational Capability Of Container Terminals, Jaehun Park, Byung Kwon Lee, Joyce M. W. Low Dec 2020

A Two-Stage Parallel Network Dea Model For Analyzing The Operational Capability Of Container Terminals, Jaehun Park, Byung Kwon Lee, Joyce M. W. Low

Research Collection Lee Kong Chian School Of Business

This study proposes a systematical approach to evaluate the operational capability of container terminals and discusses the effect of resource usages on operational performances. Two inter-dependent processes (i.e. the loading-discharging (L&D) and the delivery-receiving (D&R) operational processes) with shared/non-shared resources and common/separate productions are examined and characterized as a two-stage parallel network. An evaluation model is developed upon the principles of data envelopment analysis (DEA) to assess the operational capability of the terminals. Using the real-world dataset of 9 container terminals at Port of Busan, comparative performance results are obtained for 5 years spanning across 2014–2018. The proposed model demonstrates …


Covid-19, Coronavirus, Wuhan Virus, Or China Virus? Understanding How To “Do No Harm" When Naming An Infectious Disease, Theodore C. Masters-Waage, Nilotpal Jha, Jochen Reb Dec 2020

Covid-19, Coronavirus, Wuhan Virus, Or China Virus? Understanding How To “Do No Harm" When Naming An Infectious Disease, Theodore C. Masters-Waage, Nilotpal Jha, Jochen Reb

Research Collection Lee Kong Chian School Of Business

When labeling an infectious disease, officially sanctioned scientific names, e.g., “H1N1 virus,” are recommended over place-specific names, e.g., “Spanish flu.” This is due to concerns from policymakers and the WHO that the latter might lead to unintended stigmatization. However, with little empirical support for such negative consequences, authorities might be focusing on limited resources on an overstated issue. This paper empirically investigates the impact of naming against the current backdrop of the 2019-2020 pandemic.


Stay Mindful And Carry On: Mindfulness Neutralizes Covid-19 Stressors On Work Engagement Via Sleep Duration, Michelle Xue Zheng, Theodore Charles Masters-Waage, Jingxian Yao, Yichen Lu, Noriko Tan, Jayanth Narayanan Dec 2020

Stay Mindful And Carry On: Mindfulness Neutralizes Covid-19 Stressors On Work Engagement Via Sleep Duration, Michelle Xue Zheng, Theodore Charles Masters-Waage, Jingxian Yao, Yichen Lu, Noriko Tan, Jayanth Narayanan

Research Collection Lee Kong Chian School Of Business

We examine whether mindfulness can neutralize the negative impact of COVID-19 stressors on employees' sleep duration and work engagement. In Study 1, we conducted a field experiment in Wuhan, China during the lockdown between February 20, 2020, and March 2, 2020, in which we induced state mindfulness by randomly assigning participants to either a daily mindfulness practice or a daily mind-wandering practice. Results showed that the sleep duration of participants in the mindfulness condition, compared with the control condition, was less impacted by COVID-19 stressors (i.e., the increase of infections in the community). In Study 2, in a 10-day daily …


Trading Regularity And Fund Performance: Evidence In Uncertain Markets, Lin Tong, Zhe Zhang Dec 2020

Trading Regularity And Fund Performance: Evidence In Uncertain Markets, Lin Tong, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

High trading regularity funds outperform low trading regularity funds more during periods of low market returns and greater market and economic uncertainty. Their trading also has strong return predictability on stock returns during periods of greater uncertainty. They trade more around news events, and their news related trading predicts stock return stronger during periods of greater uncertainty. They also profit from liquidity provision in highly uncertain market environment. Overall our evidence suggests that high trading regularity funds trade more frequently during periods of high uncertainty when information production and processing skill is more valuable and when the demand for liquidity …


Form And Substance In Singapore Constitutional And Administrative Law, Kenny Chng Dec 2020

Form And Substance In Singapore Constitutional And Administrative Law, Kenny Chng

Research Collection Yong Pung How School Of Law

This paper proposes to study constitutional and administrative law in Singapore through the lenses of Atiyah’s and Summers’ concepts of form and substance in order to discern fruitful avenues for the development of Singapore constitutional and administrative law. While the concepts of form and substance in the context of constitutional law are often associated with constitutional interpretation, they can also be fruitfully applied to other areas of constitutional and administrative law to shed light on the potential trajectories of Singapore law. The intent of this paper is to apply Atiyah’s and Summers’ concepts of form and substance to Singapore constitutional …


Testing For Structural Changes In Factor Models Via A Nonparametric Regression, Liangjun Su, Xia Wang Dec 2020

Testing For Structural Changes In Factor Models Via A Nonparametric Regression, Liangjun Su, Xia Wang

Research Collection School Of Economics

We propose a model-free test for structural changes in factor models. The basic idea is to regress the data on commonly estimated factors by local smoothing and compare the fitted values of time-varying factor loadings with those of time-invariant factor loadings estimated via principal component analysis. By construction, the test is designed to be powerful against both smooth structural changes and sudden structural breaks with a possibly unknown number of breaks and unknown break dates in the factor loadings. No restrictions on the form of alternatives or trimming of boundary regions near the beginning or end of the sample period …


Diagnostic Tests For Homoskedasticity In Spatial Cross-Sectional Or Panel Models, Badi K. Baltagi, Alain Pirotte, Zhenlin Yang Dec 2020

Diagnostic Tests For Homoskedasticity In Spatial Cross-Sectional Or Panel Models, Badi K. Baltagi, Alain Pirotte, Zhenlin Yang

Research Collection School Of Economics

We propose an Adjusted Quasi-Score (AQS) method for constructing tests for homoskedasticity in spatial econometric models. We first obtain an AQS function by adjusting the score-type function from the given model to achieve unbiasedness, and then develop an Outer-Product-of-Martingale-Difference (OPMD) estimate of its variance. In standard problems where a genuine (quasi) score vector is available, the AQS-OPMD method leads to finite sample improved tests over the usual methods. More importantly in non-standard problems where a genuine (quasi) score is not available and the usual methods fail, the proposed AQS-OPMD method provides feasible solutions. The AQS tests are formally derived and …


Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma Dec 2020

Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma

Research Collection School Of Economics

The household registration system (hukou system) in China has hampered rural-urban migration by posing large migration friction. The system has been gradually relaxed in the past few decades, but the reforms have been differential in city size and by the coastal-inland divide. We find a striking contrast in the migration patterns between years 2005 and 2015; rural people tended to move more to the coastal urban region in 2005, but more to the inland urban region in 2015. We calibrate a spatial quantitative model to the world economy in both years with China being divided into the rural, coastal urban, …
