From Tools To Toolkits In Policy Design Studies: The New Design Orientation Towards Policy Formulation Research, Michael Howlett, Ishani Mukherjee, Jun Jie Woo

Research Collection School of Social Sciences

A roadmap for `new policy design' studies now exists in the orientation which has emerged in recent years towards the formulation of complex policy mixes.The new design orientation focuses on bundles or portfolios of tools and the interactive effects which occur when multiple tools are used over time in policy packages designed to address multiple goals, and upon more complex multi-policy and multi-level design contexts.This review article examines the differences between the `old' instrument orientation and the `new' design one, setting out the current research agenda in this field and its rationale.

New Directions In Hydro-Climatic Histories: Observational Data Recovery, Proxy Records And The Atmospheric Circulation Reconstructions Over The Earth (Acre) Initiative In Southeast Asia, Fiona Williamson, Rob Allan, Adam Switzer, Johnny C. L. Chan, Robert James Wasson, Rosanne D'Arrigo, Richard Gartner

Research Collection School of Social Sciences

The value of historic observational weather data for reconstructing long-term climate patterns and the detailed analysis of extreme weather events has long been recognized (Le Roy Ladurie, 1972; Lamb, 1977). In some regions however, observational data has not been kept regularly over time, or its preservation and archiving has not been considered a priority by governmental agencies. This has been a particular problem in Southeast Asia where there has been no systematic country-by-country method of keeping or preserving such data, the keeping of data only reaches back a few decades, or where instability has threatened the survival of historic records. …

Institutional Change Versus Resilience: A Study Of An Incorporation Of Independent Directors In Singapore Banks, Lai Si Tsui-Auch, Toru Yoshikawa

Research Collection Lee Kong Chian School Of Business

We examine how Anglo-American capital market logic penetrated into Singapore where relational logic tends to guide business activities and illustrate how domestic banks reacted to this imported logic in the corporate governance field. We argue that the banks’ ability to accommodate competing logics was enhanced by state agencies’ willingness to modify Anglo-American standards to fit the local context. Given the resulting institutional ambiguities in rules, local banks, while incorporating higher outside representation on their boards, reinterpreted the meaning of independence and emphasized the resource provision role rather than the monitoring function of outside directors. The resultant institutional change has been …

Is Comfort Food Really Good For The Soul? A Replication Of Troisi And Gabriel's (2011) Study 2, Lay See Ong, Hans Ijzerman, Ka Yee Angela Leung

Research Collection School of Social Sciences

We report the results of three high-powered replications of Troisi and Gabriel's (2011) idea that writing about comfort food reduces feelings of loneliness amongst securely attached individuals after a belongingness threat. We conducted our studies amongst a large group of participants (Total N = 649) amongst American (MTurk), Dutch (Tilburg University; TiU), and Singaporean (Singapore Management University; SMU) samples. Participants first completed an attachment style scale, followed by writing two essays for manipulating a sense of belongingness and salience of comfort food, and then reporting their loneliness levels. We did not confirm the overall effect over all three countries. However, …

Impacts Of Beijing Bus Rapid Transit On Pre-Owned Home Values, Hao Pang, Junfeng Jiao

Research Collection College of Integrative Studies

Bus Rapid Transit (BRT) has gained increasing popularity worldwide in the last few decades. However, few studies have investigated BRT’s impacts on property values in Chinese cities. This research, taking BRT route 1 (BRT1) and BRT route 3 (BRT3) in Beijing as examples, showed that proximity to BRT3 stops is weakly related to pre-owned home prices along the route, whereas BRT1 has induced a significant price premium. For BRT1, the impact is not linear. Specifically, pre-owned home prices for homes within 5–10 minutes’ walking distance to BRT stations is 5.35% higher than those located closer to or farther away. The …

Financial Health And Corporate Performance Of Listed Manufacturing Companies In Hong Kong And Singapore – A Comparative Study Of The Two Asian Tigers, Foo S.L.

Research Collection School Of Accountancy

Hong Kong and Singapore are two leading economies in Asia Pacific. This study examines the relationship between the financial health, as measured by the Altman Z-Score, and corporate performance, as measured by the Return on Equity (ROE), of listed manufacturing companies in these two markets. A linear regression was conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a fourteen-year period are also analyzed. The analysis covers the period from 2000 to 2013(inclusive) and yielded a statistically positive correlation between ROE and the Z-Score for both markets. Singapore and Hong Kong …

Disaggregating Activities Of Daily Living Limitations For Predicting Nursing Home Admission, Joelle H. Y. Fong, Olivia S. Mitchell, Benedict S. K. Koh

Research Collection Lee Kong Chian School Of Business

Objective: To examine whether disaggregated activities of daily living (ADL) limitations better predict the risk of nursing home admission compared to conventionally used ADL disability counts. Data Sources: We used panel data from the Health and Retirement Study (HRS) for years 1998–2010. The HRS is a nationally representative survey of adults older than 50 years (n = 18,801). Study Design: We fitted Cox regressions in a continuous time survival model with age at first nursing home admission as the outcome. Time-varying ADL disability types were the key explanatory variables. Principal Findings: Of the six ADL limitations, bathing difficulty emerged as …

Does The Obligation To Obtain The Consent Of A Third Party Extend To Taking Further Steps After Rejection?, Yihan Goh

Research Collection Yong Pung How School Of Law

The question posed in the Court of Appeal case of The One Suites Pte Ltd v Pacific Motor Credit (Pte) Ltd [2015] SGCA 21 (“The One Suites”) was whether an obligation to use all reasonable endeavours to obtain the consent of a third party extends to taking further steps after the third party had refused to give such consent. To this, the Court, with Andrew Phang Boon Leong JA writing its grounds of decision, answered, “it depends but largely no”. More precisely, the Court said that while there almost invariably will be an implied obligation to use all reasonable endeavours …

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

Research Collection School Of Economics

We consider the problem of determining the number of factors and selecting the proper regressors in linear dynamic panel data models with interactive fixed effects. Based on the preliminary estimates of the slope parameters and factors a la Bai and Ng (2009) and Moon andWeidner (2014a), we propose a method for simultaneous selection of regressors and factors and estimation through the method of adaptive group Lasso (least absolute shrinkage and selection operator). We show that with probability approaching one, our method can correctly select all relevant regressors and factors and shrink the coefficients of irrelevant regressors and redundant factors to …

Welfare-To-Work Reform And Intergenerational Support: Grandmothers' Response To The 1996 Prwora, Ho, Christine

Research Collection School Of Economics

The 1996 Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA; Pub. L. 104-193) in the United States aimed at encouraging work among low-income mothers with children below age 18. In this study, the author used a sample of 2,843 intergenerational family observations from the Health and Retirement Study to estimate the effects of the reform on single grandmothers who are related to those mothers. The results suggest that the reform decreased time transfers but increased money transfers from grandmothers. The results are consistent with an intergenerational family support network where higher child care subsidies motivated the family to shift away …

Home Prices And Inequality: Singapore Versus Other Global Superstar Cities, Sock Yong Phang

Research Collection School Of Economics

The Global City concept originates from the work of sociologist Saskia Sassen, which dates back to the 1980s. In an age of globalisation, division of labour is international in scope and production activities are distributed across the world. A global city is a significant point where the internationally oriented financial and producer services that make the global economy run choose to agglomerate.

A Combined Approach To The Inference Of Conditional Factor Models, Yan Li, Liangjun Su, Yuewa Xu

Research Collection School Of Economics

This article develops a new methodology for estimating and testing conditional factor models in finance. We propose a two-stage procedure that naturally unifies the two existing approaches in the finance literature-the parametric approach and the nonparametric approach. Our combined approach possesses important advantages over both methods. Using our two-stage combined estimator, we derive new test statistics for investigating key hypotheses in the context of conditional factor models. Our tests can be performed on a single asset or jointly across multiple assets. We further propose a novel test to directly check whether the parametric model used in our first stage is …

Optimal Jackknife For Unit Root Models, Ye Chen, Jun Yu

Research Collection School Of Economics

A new jackknife method is introduced to remove the first order bias in unit root models. It is optimal in the sense that it minimizes the variance among all the jackknife estimators of the form considered in Phillips and Yu (2005) and Chambers and Kyriacou (2013) after the number of subsamples is selected. Simulations show that the new jackknife reduces the variance of that of Chambers and Kyriacou by about 10% for any selected number of subsamples without compromising bias reduction. The results continue to hold true in near unit root models. (C) 2014 Elsevier B.V. All rights reserved.

Inefficiency In The Shadow Of Unobservable Reservation Payoffs, Madhav S. Aney

Research Collection School Of Economics

This paper considers the problem of allocating an object between two players in an environment with one sided asymmetric information when their reservation payoffs depend on the type of the informed player, causing the reservation payoff of the uninformed player to be unobservable to her. Inefficiency arises naturally in this setting and can be characterized by a simple condition on the reservation payoffs that is necessary and sufficient. I derive the necessary and sufficient condition for the existence of an implementable allocation that at least weakly dominates the reservation payoffs. Under a mild assumption on the distribution of types, I …

Electric Vehicles With A Battery Switching Station: Adoption And Environmental Impact, Buket Avci, Karan Girotra, Serguei Netessine

Research Collection Lee Kong Chian School Of Business

The transportation sector's carbon footprint and dependence on oil are of deep concern to policy makers in many countries. Use of all-electric drive trains is arguably the most realistic medium-term solution to address these concerns. However, motorist anxiety induced by an electric vehicle's limited range and high battery cost have constrained consumer adoption. A novel switching-station-based solution is touted as a promising remedy. Vehicles use standardized batteries that, when depleted, can be switched for fully charged batteries at switching stations, and motorists only pay for battery use. We build a model that highlights the key mechanisms driving adoption and use …

West Meets East: New Concepts And Theories, Harry G. Barkema, Xiao-Ping Chen, Gerard George, Yadong Luo, Anne S. Tsui

Research Collection Lee Kong Chian School Of Business

Management scholarship has grown tremendously over the past 60 years. Most of our paradigms originated from North America in the 1950s to the 1980s, inspired by the empirical phenomena and cultural, philosophical, and research traditions of the time. Here following, we highlight the contextual differences between the East and the West in terms of institutions, philosophies, and cultural values and how they are manifest in contemporary management practices. Inspired by theory development in management studies over time, we offer insights into the conditions facilitating new theories, and how these might apply to emergent theories from the East. We discuss the …

Lag Length Selection For Unit Root Tests In The Presence Of Nonstationary Volatility, Giuseppe Cavaliere, Peter C. B. Phillips, Stephan Smeekes, A. M. Robert Taylor

Research Collection School Of Economics

A number of recent papers have focused on the problem of testing for a unit root in the case where the driving shocks may be unconditionally heteroskedastic. These papers have, however, taken the lag length in the unit root test regression to be a deterministic function of the sample size, rather than data-determined, the latter being standard empirical practice. We investigate the finite sample impact of unconditional heteroskedasticity on conventional data-dependent lag selection methods in augmented Dickey–Fuller type regressions and propose new lag selection criteria which allow for unconditional heteroskedasticity. Standard lag selection methods are shown to have a tendency …

Nonparametric Predictive Regression, Ioannis Kasparis, Elena Andreou, Peter C. B. Phillips

Research Collection School Of Economics

A unifying framework for inference is developed in predictive regressions where the predictor has unknown integration properties and may be stationary or nonstationary. Two easily implemented nonparametric F-tests are proposed. The limit distribution of these predictive tests is nuisance parameter free and holds for a wide range of predictors including stationary as well as non-stationary fractional and near unit root processes. Asymptotic theory and simulations show that the proposed tests are more powerful than existing parametric predictability tests when deviations from unity are large or the predictive regression is nonlinear. Empirical illustrations to monthly SP500 stock returns data are provided. …

Forensically Discovering Simulation Feedback Knowledge From A Campus Energy Information System, Clayton Miller, Arno Schlueter

Research Collection College of Integrative Studies

Simulation model calibration has been long identified as a key means of reconciling the consumption and efficiency characteristics of buildings. A key step in this process is the creation of the actual diversity factor profiles for occupancy and various energy end uses such as lighting, plug-loads, and HVAC. Creation of these model inputs is conventionally a tedious process of site surveys, interviews or temporary sensor installation. Sometimes measured energy data can be used to create these schedules, however there are many challenges, especially when the sensor network available is large or unorganized. This paper describes a process applying a series …

Review Selection Using Micro-Reviews, Thanh-Son Nguyen, Hady W. Lauw, Panayiotis Tsaparas

Research Collection School Of Computing and Information Systems

Given the proliferation of review content, and the fact that reviews are highly diverse and often unnecessarily verbose, users frequently face the problem of selecting the appropriate reviews to consume. Micro-reviews are emerging as a new type of online review content in the social media. Micro-reviews are posted by users of check-in services such as Foursquare. They are concise (up to 200 characters long) and highly focused, in contrast to the comprehensive and verbose reviews. In this paper, we propose a novel mining problem, which brings together these two disparate sources of review content. Specifically, we use coverage of micro-reviews …

Measuring User Influence, Susceptibility And Cynicalness In Sentiment Diffusion, Roy Ka-Wei Lee, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Diffusion in social networks is an important research topic lately due to massive amount of information shared on social media and Web. As information diffuses, users express sentiments which can affect the sentiments of others. In this paper, we analyze how users reinforce or modify sentiment of one another based on a set of inter-dependent latent user factors as they are engaged in diffusion of event information. We introduce these sentiment-based latent user factors, namely influence, susceptibility and cynicalness. We also propose the ISC model to relate the three factors together and develop an iterative computation approach to …
