Case Comment: A New Framework For The Implication Of Terms In Fact, Yihan Goh Dec 2013

Case Comment: A New Framework For The Implication Of Terms In Fact, Yihan Goh

Research Collection School Of Law

In Sembcorp Marine Ltd v PPL Holdings Pte Ltd the Singapore Court of Appeal once again reaffirmed the Singapore courts’ rejection of the approach adopted by Lord Hoffmann in Attorney General of Belize v Belize Telecom Ltd which characterised the implication of a term in fact as a process of contractual interpretation. What may be of interest to practitioners and academics of common law jurisdictions wrestling with the implications of the Belize approach is the Court of Appeal’s prescription of ‘a three-step process’ for the implication of terms in fact, which is accompanied by an in-depth discussion of various ...

What You Want Is Not What You Get: Predicting Sharing Policies For Text-Based Content On Facebook, Arunesh Sinha, Yan Li, Lujo Bauer Dec 2013

What You Want Is Not What You Get: Predicting Sharing Policies For Text-Based Content On Facebook, Arunesh Sinha, Yan Li, Lujo Bauer

Research Collection Lee Kong Chian School Of Business

As the amount of content users publish on social networking sites rises, so do the danger and costs of inadvertently sharing content with an unintended audience. Studies repeatedly show that users frequently misconfigure their policies or misunderstand the privacy features offered by social networks. A way to mitigate these problems is to develop automated tools to assist users in correctly setting their policy. This paper explores the viability of one such approach: we examine the extent to which machine learning can be used to deduce users' sharing preferences for content posted on Facebook. To generate data on which to evaluate ...


The Fiduciary Doctrine As A New Pathway: An Alternative Approach To Analysing Native Customary Rights In Sarawak, Hang Wu Tang Dec 2013

The Fiduciary Doctrine As A New Pathway: An Alternative Approach To Analysing Native Customary Rights In Sarawak, Hang Wu Tang

Research Collection School Of Law

This paper explores the use of the fiduciary doctrine whereby the state is conceived as a fiduciary vis-à-vis her native peoples and attendant equitable remedies are made available for the native customary rights over land in Sarawak. Thus far, most challenges to extinguishment of native customary rights in Sarawak have proceeded on constitutional grounds, with little success. This article draws on the jurisprudence of fiduciary law in other parts of the Commonwealth and argues that this is a viable alternative cause of action against the state.


Quasi-Maximum Likelihood Estimation For Spatial Panel Data Regressions, Zhenlin Yang Dec 2013

Quasi-Maximum Likelihood Estimation For Spatial Panel Data Regressions, Zhenlin Yang

Research Collection School Of Economics

This article considers quasi-maximum likelihood estimations (QMLE) for two spatial panel data regression models: mixed effects model with spatial errors and transformed mixed effects model (where response and covariates are transformed) with spatial errors. One aim of transformation is to normalize the data, thus the transformed models are more robust with respect to the normality assumption compared with the standard ones. QMLE method provides additional protection against violation of normality assumption. Asymptotic properties of the QMLEs are investigated. Numerical illustrations are provided.


Minimum Investment Requirement, Financial Integration And Economic (In)Stability: A Refinement To Matsuyama (2004), Haiping Zhang Dec 2013

Minimum Investment Requirement, Financial Integration And Economic (In)Stability: A Refinement To Matsuyama (2004), Haiping Zhang

Research Collection School Of Economics

This note proposes a simple, more precise, necessary condition for symmetry breaking in Matsuyama (Financial Market Globalization, Symmetry-Breaking, and Endogenous Inequality of Nations, Econometrica, 2004 ), i.e., the positive interest rate response to income changes, which essentially arises from the assumptions of financial frictions and minimum investment size requirement of individual projects. This condition also holds under the more general settings. Thus, this note o ers an empirically testable hypothesis, i.e., Matsuyama's symmetry breaking is more likely, if the interest rate response to income changes is positive and sufficiently large.


Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips Dec 2013

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips

Research Collection School Of Economics

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized regression techniques. We focus on linear models where the slope parameters are heterogeneous across groups but homogenous within a group and the group membership is unknown. Two approaches are considered -- penalized least squares (PLS) for models without endogenous regressors, and penalized GMM (PGMM) for models with endogeneity. In both cases we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and consistent estimation in a single step ...


In Search Of The Impactful And The Interesting: Swings Of The Pendulum?, Timothy Adrian Robert Clark, Steven W. Floyd, Mike Wright Dec 2013

In Search Of The Impactful And The Interesting: Swings Of The Pendulum?, Timothy Adrian Robert Clark, Steven W. Floyd, Mike Wright

Research Collection Lee Kong Chian School Of Business

In this article we reflect on our time as editors of JMS during the period 2003-09. First we describe the context as we saw it on assuming editorship of the Journal and the actions that we took to improve the quality of scholarship published in the journal in order to set JMS on the trajectory to become a world-leading Journal. We articulate our view of what quality means in this context and observe that we eschewed the USA-Europe divide. Rather, to be publishable, all papers had to meet the highest standards relative to their epistemological assumptions. Finally, we address two ...


Social Media Hype In Times Of Crises: Nature, Characteristics And Impact On Organizations, Augustine Pang Dec 2013

Social Media Hype In Times Of Crises: Nature, Characteristics And Impact On Organizations, Augustine Pang

Research Collection Lee Kong Chian School Of Business

This article extends Vasterman’s (2005) concept of media hype by analyzing how it applies in the social media context. It then develops the concept of social media hype, its nature, characteristics through examination of five cases that attracted much social media attention. Social media hype can be defined as a netizen-generated hype that causes huge interest that is triggered by a key event and sustained by a self-reinforcing quality in its ability for users to engage in conversation. It involves a trigger event, followed by interest waves, and sustaining of the interests on different social media platforms. In response ...


Testing Homogeneity In Panel Data Models With Interactive Fixed Effects, Liangjun Su, Qihui Chen Dec 2013

Testing Homogeneity In Panel Data Models With Interactive Fixed Effects, Liangjun Su, Qihui Chen

Research Collection School Of Economics

This paper proposes a residual-based LM test for slope homogeneity in large dimensional panel data models with interactive fixed effects. We first run the panel regression under the null to obtain the restricted residuals, and then use them to construct our LM test statistic. We show that after being appropriately centered and scaled, our test statistic is asymptotically normally distributed under the null and a sequence of Pitman local alternatives. The asymptotic distributional theories are established under fairly general conditions which allow for both lagged dependent variables and conditional heteroskedasticity of unknown form by relying on the concept of conditional ...


Testing For Indirect Reciprocity In Charitable Activities, Christine Ho Dec 2013

Testing For Indirect Reciprocity In Charitable Activities, Christine Ho

Research Collection School Of Economics

We propose a test of indirect reciprocity using US data on charitable activities in terms of both time and money. We find that expecting help from friends or relatives in the future positively affects the probability and the amount of charitable activities performed.


Contrasting Perspectives On China's Rare Earths Policies: Reframing The Debate Through A Stakeholder Lens, Leslie Hayes-Labruto, Simon J.D. Schillebeeckx, Mark Workman, Nilay Shah Dec 2013

Contrasting Perspectives On China's Rare Earths Policies: Reframing The Debate Through A Stakeholder Lens, Leslie Hayes-Labruto, Simon J.D. Schillebeeckx, Mark Workman, Nilay Shah

Research Collection Lee Kong Chian School Of Business

This article critically compares China's rare earth policy with perspectives upheld in the rest of the world (ROW). We introduce rare earth elements and their importance for energy and present how China and the ROW are framing the policy debate. We find strongly dissonant views with regards to motives for foreign direct investment, China's two-tiered pricing structure and its questionable innovation potential. Using the metaphor of "China Inc.", we compare the Chinese government to a socially responsible corporation that aims to balance the needs of its internal stakeholders with the demands from a resource-dependent world. We find that ...


A State Space Model Approach To Integrated Covariance Matrix Estimation With High Frequency Data, Cheng Liu, Cheng Yong Tang Dec 2013

A State Space Model Approach To Integrated Covariance Matrix Estimation With High Frequency Data, Cheng Liu, Cheng Yong Tang

Research Collection Lee Kong Chian School Of Business

We consider a state space model approach forhigh frequency financial data analysis. An expectationmaximization(EM) algorithm is developed for estimatingthe integrated covariance matrix of the assets. The statespace model with the EM algorithm can handle noisy financialdata with correlated microstructure noises. Difficultydue to asynchronous and irregularly spaced trading data ofmultiple assets can be naturally overcome by consideringthe problem in a scenario with missing data. Since the statespace model approach requires no data synchronization, norecord in the financial data is deleted so that it efficientlyincorporates information from all observations. Empiricaldata analysis supports the general specification of the statespace model, and simulations ...


Topicsketch: Real-Time Bursty Topic Detection From Twitter, Wei Xie, Feida Zhu, Jing Jiang, Ee Peng Lim, Ke Wang Dec 2013

Topicsketch: Real-Time Bursty Topic Detection From Twitter, Wei Xie, Feida Zhu, Jing Jiang, Ee Peng Lim, Ke Wang

Research Collection School Of Information Systems

Twitter has become one of the largest platforms for users around the world to share anything happening around them with friends and beyond. A bursty topic in Twitter is one that triggers a surge of relevant tweets within a short time, which often reflects important events of mass interest. How to leverage Twitter for early detection of bursty topics has therefore become an important research problem with immense practical value. Despite the wealth of research work on topic modeling and analysis in Twitter, it remains a huge challenge to detect bursty topics in real-time. As existing methods can hardly scale ...


Two Formulas For Success In Social Media: Social Learning And Network Effects, Liangfei Qiu, Qian Tang, Andrew B. Whinston Dec 2013

Two Formulas For Success In Social Media: Social Learning And Network Effects, Liangfei Qiu, Qian Tang, Andrew B. Whinston

Research Collection School Of Information Systems

This paper examines social learning and network effects that are particularly important for online videos, considering the limited marketing campaigns of user-generated content. Rather than combining both social learning and network effects under the umbrella of social contagion or peer influence, we develop a theoretical model and empirically identify social learning and network effects separately. Using a unique data set from YouTube, we find that both mechanisms have statistically and economically significant effects on video views, and which mechanism dominates depends on the specific video type.

The Court of Appeal affirmed the High Court’s ruling that the applicant had no locus standito challenge the compatibility of a loan made by the Government to the InternationalMonetary Fund with Art 144(1) of the Constitution. On the interpretation of Art 144(1), therewas no prima facie case of reasonable suspicion that such incompatibility existed. Moreover,the applicant did not have sufficient interest in the matter.


From Emotions To Shared Values, David Chan Dec 2013

From Emotions To Shared Values, David Chan

Research Collection School of Social Sciences

In an invited commentary, SMU director of Behavioural Sciences Institute Professor David Chan noted that although the negative emotions that dominated 2013 have led to some positive outcomes, emotions cannot be the foundation for society’s progress. Professor Chan suggested that, moving forward, Singapore should focus on three shared values (integrity, fairness, social harmony) and three guiding principles (rule of law, accountability, people-centricity).


Recruiting The All-Female Rani Of Jhansi Regiment: Subhas Chandra Bose And Dr Lakshmi Swaminadhan, Tobias Frederik Rettig Dec 2013

Recruiting The All-Female Rani Of Jhansi Regiment: Subhas Chandra Bose And Dr Lakshmi Swaminadhan, Tobias Frederik Rettig

Research Collection School of Social Sciences

The recruitment of the all-female Rani of Jhansi Regiment of the Indian National Army in Japanese-controlled Singapore and Malaya, with a particular focus on the period between the first female guard of honour on 12 July 1943 through to the opening of the regiment's main camp in Singapore on 22 October 1943, has to date been insufficiently studied. Starting with the conception of the Regiment in an Axis submarine by the Indian nationalist leader Subhas CHANdra Bose (1897–1945), this paper examines the ideas and figures that inspired the regiment and the role of Bose and Dr Lakshmi Swaminadhan ...


Predictive Regression Under Various Degrees Of Persistence And Robust Long-Horizon Regression, Peter C. B. Phillips, Ji Hyung Lee Dec 2013

Predictive Regression Under Various Degrees Of Persistence And Robust Long-Horizon Regression, Peter C. B. Phillips, Ji Hyung Lee

Research Collection School Of Economics

The paper proposes a novel inference procedure for long-horizon predictive regression with persistent regressors, allowing the autoregressive roots to lie in a wide vicinity of unity. The invalidity of conventional tests when regressors are persistent has led to a large literature dealing with inference in predictive regressions with local to unity regressors. Magdalinos and Phillips (2009b) recently developed a new framework of extended IV procedures (IVX) that enables robtist chi-square testing for a wider class of persistent regressors. We extend this robust procedure to an even wider parameter space in the vicinity of unity and apply the methods to long-horizon ...


Detecting Well-Being Via Computerized Content Analysis Of Brief Diary Entries, William Tov, Kok Leong Ng, Han Lin, Lin Qiu Dec 2013

Detecting Well-Being Via Computerized Content Analysis Of Brief Diary Entries, William Tov, Kok Leong Ng, Han Lin, Lin Qiu

Research Collection School of Social Sciences

Two studies evaluated the correspondence between self-reported well-being and codings of emotion and life content by the Linguistic Inquiry and Word Count (LIWC; Pennebaker, Booth, & Francis, 2011). Open-ended diary responses were collected from 206 participants daily for 3 weeks (Study 1) and from 139 participants twice a week for 8 weeks (Study 2). LIWC negative emotion consistently correlated with self-reported negative emotion. LIWC positive emotion correlated with self-reported positive emotion in Study 1 but not in Study 2. No correlations were observed with global life satisfaction. Using a co-occurrence coding method to combine LIWC emotion codings with life-content codings, we ...


Financial Reporting Quality Of Chinese Reverse Merger Firms: The Reverse Merger Effect Or The China Effect?, Kun-Chih Chen, Qiang Cheng, Ying Chou Lin, Yu-Chen Lin, Xing Xiao Dec 2013

Financial Reporting Quality Of Chinese Reverse Merger Firms: The Reverse Merger Effect Or The China Effect?, Kun-Chih Chen, Qiang Cheng, Ying Chou Lin, Yu-Chen Lin, Xing Xiao

Research Collection School Of Accountancy

In this paper, we examine why Chinese reverse merger (RM) firms have lower financial reporting quality. We find that while U.S. RM firms have similar financial reporting quality as matched U.S. IPO firms, Chinese RM firms exhibit lower financial reporting quality than Chinese ADR firms. We further find that Chinese RM firms exhibit lower financial reporting quality than U.S. RM firms. These results indicate that the use of RM process is associated with poor financial reporting quality only in firms from China, where the legal enforcement is weaker than U.S. In addition, we find that compared ...

Corporate Social Responsibility – An Idealistic Goal Or A Reality?, Singapore Management University Nov 2013

Corporate Social Responsibility – An Idealistic Goal Or A Reality?, Singapore Management University

Perspectives@SMU

Despite widespread discussion on CSR, there continues to be much disagreement around what constitutes CSR, and how to define it. In addition, the term is often used interchangeably with notions such as corporate responsibility, corporate citizenship, triple-bottom line, sustainability, creating shared value, and in some cases, corporate ethics and governance. However, all of these ideas point in the same direction: a sharp escalation in the social roles corporations are expected to play today.


Estimation Of Time Varying Adjusted Probability Of Informed Trading And Probability Of Symmetric Order-Flow Shock, Daniel Preve, Yiu Kuen Tse Nov 2013

Estimation Of Time Varying Adjusted Probability Of Informed Trading And Probability Of Symmetric Order-Flow Shock, Daniel Preve, Yiu Kuen Tse

Research Collection School Of Economics

Recently Duarte and Young (2009) study the probability of informed trading (PIN) proposed by Easley et al. (2002) and decompose it into two parts: the adjusted PIN (APIN) as a measure of asymmetric information and the probability of symmetric order-flow shock (PSOS) as a measure of illiquidity. They provide some cross-section estimates of these measures using daily data over annual periods. In this paper we propose a method to estimate daily APIN and PSOS by extending the method in Tay et al. (2009) using high-frequency transaction data. Our empirical results show that while PIN is positively contemporaneously correlated with variance ...
