Urban Rail Transit Ppps: Lessons From East Asian Cities, Zheng Chang, Sock Yong Phang Nov 2017

Urban Rail Transit Ppps: Lessons From East Asian Cities, Zheng Chang, Sock Yong Phang

Research Collection School Of Economics

Private sector participation in urban rail transit has proliferated in the past two decades. The large metropolises of East Asia have had decades of experience with private sector participation in the provision of heavy metro services. The design of these public–private partnerships (PPP) are varied. The diverse experiences of Tokyo, Hong Kong, Singapore and Beijing contain valuable lessons for other cities. Using a case study approach, this paper discusses three features of urban rail transitdevelopments in the context of East Asian cities, viz., farebox recovery, land value capture mechanisms, and vertical structure of the industry. Super vertical integration between rail …

The Role Of Macroeconomic, Policy, And Forecaster Uncertainty In Forecast Dispersion, You Li, Anthony S. Tay Nov 2017

The Role Of Macroeconomic, Policy, And Forecaster Uncertainty In Forecast Dispersion, You Li, Anthony S. Tay

Research Collection School Of Economics

We explore the role of uncertainty in explaining dispersion in professional forecasters’ density forecasts of real output growth and inflation. We consider three separate notions of uncertainty: general macroeconomic uncertainty (the fact that macroeconomic variables are easier to forecast at some times than at others), policy uncertainty, and forecaster uncertainty. We find that dispersion in individual density forecasts is related to overall macroeconomic uncertainty and policy uncertainty, while forecaster uncertainty (which we define as the average in the uncertainty expressed by individual forecasters) appears to have little role in forecast dispersion.

Does "America First" Help America? The Impact Of Country Image On Exports And Welfare, Pao-Li Chang, Tomoki Fujii, Wei Jin Nov 2017

Does "America First" Help America? The Impact Of Country Image On Exports And Welfare, Pao-Li Chang, Tomoki Fujii, Wei Jin

Research Collection School Of Economics

This paper estimates the effects of bilateral and time-varying preference bias on trade flows and welfare. We use a unique dataset from the BBC World Opinion Poll that surveys (annually during 2005-2017 with some gaps) the populations from a wide array of countries on their views of whether an evaluated country is having a mainly positive or negative influence in the world. We identify the effects on bilateral preference parameters due to shifts in these country image perceptions, and quantify their general equilibrium effects on bilateral exports and welfare (each time for an evaluated exporting country, assuming that the exporting …

Permanent Price Impact Asymmetry Of Trades With Institutional Constraints, Chiraphol N. Chiyachantana, Pankaj Jain, Christine Jiang, Vivek Sharma Nov 2017

Permanent Price Impact Asymmetry Of Trades With Institutional Constraints, Chiraphol N. Chiyachantana, Pankaj Jain, Christine Jiang, Vivek Sharma

Research Collection Lee Kong Chian School Of Business

Dynamic institutional trading constraints related to capital, diversification, and short-selling asymmetrically affect the incorporation of new information as reflected in the permanent price impact of their trades. The sign of the permanent price impact asymmetry between institutional buys versus sells is positive at the initial stage of a price run-up and reverses due to changing constraints with a prolonged price run-up in a stock. Idiosyncratic volatility, analyst forecast dispersion, trading intensity, price dispersion, and bullish market conditions further sharpen the initial asymmetry, as well as its reversal after a price run-up.

Volatility Spillovers And Linkages In Asian Stock Markets, Hwee Kwan Chow-Tan Nov 2017

Volatility Spillovers And Linkages In Asian Stock Markets, Hwee Kwan Chow-Tan

Research Collection School Of Economics

Diebold-Yilmaz spilloverindexes are computed for weekly return volatilities based on daily benchmarkstock indexes of US, UK and ten Asian countries. We found (i) the strengthening ofoverall volatility spillovers is not a temporary surge but persisted after thecrisis; (ii) the susceptibility ofindividual Asian stock markets to inward volatility transfers is linked to itsdegree of openness; and (iii) the Asian bourses are becoming more importantemitters of financial shocks since the crisis. Rolling regressions on volatilitylinkages reveal the relative dominance of the US over the Japanese and Chinesebourses, and the level of influence on Asian stock markets from the Chinesebourse has risen to …

Random Coefficient Continuous Systems: Testing For Extreme Sample Path Behaviour, Yubo Tao, Peter C. B. Phillips, Jun Yu Nov 2017

Random Coefficient Continuous Systems: Testing For Extreme Sample Path Behaviour, Yubo Tao, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper studies a continuous time dynamic system with a random persistence parameter. The exact discrete time representation is obtained and related to several discrete time random coefficient models currently in the literature. The model distinguishes various forms of unstable and explosive behaviour according to specific regions of the parameter space that open up the potential for testing these forms of extreme behaviour. A two-stage approach that employs realized volatility is proposed for the continuous system estimation, asymptotic theory is developed, and test statistics to identify the different forms of extreme sample path behaviour are proposed. Simulations show that the …

The Weekend Effect In Television Viewership And Prime-Time Scheduling, Jung Won Yeo Nov 2017

The Weekend Effect In Television Viewership And Prime-Time Scheduling, Jung Won Yeo

Research Collection School Of Economics

The observed drops in the ratings of television programs on Fridays and Saturdays are likely a result of two factors: intrinsic contraction in demand for television watching and endogenous scheduling. I decompose the observed weekend effect into the effects from these two factors. To this end, I estimate a viewer choice model that uses aggregate Nielsen ratings data for prime-time network television shows over 11 years. The long span of the data enables me to control for television series qualities. The estimation results reveal that the estimated weekend effect is dampened as the empirical model accounts for variation in the …

Spatiotemporal Identification Of Anomalies In A Wildlife Preserve, Bharadwaj Kishan, Jason Guan Jie Ong, Yanrong Zhang, Tin Seong Kam Oct 2017

Spatiotemporal Identification Of Anomalies In A Wildlife Preserve, Bharadwaj Kishan, Jason Guan Jie Ong, Yanrong Zhang, Tin Seong Kam

Research Collection School Of Computing and Information Systems

The datasets released for the VAST Challenge 2017 comprise vehicle movement data captured with RFID sensors, chemical emission data from factories captured by gas sensors, and image attributes of the wildlife plant health obtained from satellites, all pertaining to a fictional wildlife preserve. Using visual analytics, a compelling hypothesis is established to link the spatiotemporal datasets to the phenomenon, where the count of a bird specimen is found to decline over a given year. Anomalies in vehicle traffic patterns are linked to proximal factory emissions, and further associated with satellite imagery that show proof of degradation in plant quality in …

Combinatorial Auction For Transportation Matching Service: Formulation And Adaptive Large Neighborhood Search Heuristic, Baoxiang Li, Hoong Chuin Lau Oct 2017

Combinatorial Auction For Transportation Matching Service: Formulation And Adaptive Large Neighborhood Search Heuristic, Baoxiang Li, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

This paper considers the problem of matching multiple shippers and multi-transporters for pickups and drop-offs, where the goal is to select a subset of group jobs (shipper bids) that maximizes profit. This is the underlying winner determination problem in an online auction-based vehicle sharing platform that matches transportation demand and supply, particularly in a B2B last-mile setting. Each shipper bid contains multiple jobs, and each job has a weight, volume, pickup location, delivery location and time window. On the other hand, each transporter bid specifies the vehicle capacity, available time periods, and a cost structure. This double-sided auction will be …

Predicting The Brexit Vote By Tracking And Classifying Public Opinion Using Twitter Data, Julio C. Amador Diaz Lopez, Sofia Collignon-Delmar, Kenneth Benoit, Akitaka Matsuo Oct 2017

Predicting The Brexit Vote By Tracking And Classifying Public Opinion Using Twitter Data, Julio C. Amador Diaz Lopez, Sofia Collignon-Delmar, Kenneth Benoit, Akitaka Matsuo

Research Collection School of Social Sciences

We use 23M Tweets related to the EU referendum in the UK to predict the Brexit vote. In particular, we use user-generated labels known as hashtags to build training sets related to the Leave/Remain campaign. Next, we train SVMs in order to classify Tweets. Finally, we compare our results to Internet and telephone polls. This approach not only allows to reduce the time of hand-coding data to create a training set, but also achieves high level of correlations with Internet polls. Our results suggest that Twitter data may be a suitable substitute for Internet polls and may be a useful …

Community Engagement As A Form Of Participatory Governance, Ijlal Naqvi Oct 2017

Community Engagement As A Form Of Participatory Governance, Ijlal Naqvi

Research Collection School of Social Sciences

The Singapore government increasingly conducts a wide-rangingvariety of community engagement, which involve some degree ofpublic participation in government decision-making. These range fromOur Singapore Conversation, a wide-ranging discussion of whatSingaporeans want for their future, to the Colour Your Busescampaign in which citizens could vote on whether public buses shouldbe red or green. While these engagement processes typically informand consult, or occasionally involve deliberation and co-creation, theyrarely — if ever — empower citizens to make consequential decisionsin the manner of Archon Fung and Erik Olin Wright’s concept ofEmpowered Participatory Governance (2003).

Angry Faces Are More Resistant To Forgetting Than Are Happy Faces: Directed Forgetting Effects On The Identity Of Emotional Faces, Peter Kay Chai Tay, Hwajin Yang Oct 2017

Angry Faces Are More Resistant To Forgetting Than Are Happy Faces: Directed Forgetting Effects On The Identity Of Emotional Faces, Peter Kay Chai Tay, Hwajin Yang

Research Collection School of Social Sciences

Using the item-method directed forgetting paradigm (i.e. intentionally forgetting specified information), we examined directed forgetting of facial identity as a function of facial expression and the sex of the expresser and perceiver. Participants were presented with happy and angry male and female faces cued for either forgetting or remembering, and were then asked to recognise previously studied faces from among a series of neutral faces. For each recognised test face, participants also recalled the face’s previously displayed emotional expression. We found that angry faces were more resistant to forgetting than were happy faces. Furthermore, angry expressions on male faces and …

A Graph Database Framework For Covert Network Analysis: An Application To The Islamic State Network In Europe, Alexander Gutfraind, Michael Genkin Oct 2017

A Graph Database Framework For Covert Network Analysis: An Application To The Islamic State Network In Europe, Alexander Gutfraind, Michael Genkin

Research Collection School of Social Sciences

This paper proposes a new framework based on graph database theory for encoding complex data on covert networks, mapping their structure and conducting a sensitivity analysis.The framework is then applied to reconstruct the terrorist network of the 2015-2016 attacks in Paris and Brussels, and related plots in Europe by the Islamic State group (IS). The resulting network was found to be qualitatively different from the ideologically-related Al-Qaeda network, having a lower secrecy and lower mean degree, under different network-generating assumptions.

The Rcep And Its Investment Rules: Learning From Past Chinese Ftas, Heng Wang Oct 2017

The Rcep And Its Investment Rules: Learning From Past Chinese Ftas, Heng Wang

Research Collection Yong Pung How School Of Law

China’s free trade agreements (FTAs) reveal malleability as the most striking feature. The paper analyzes the following questions: what is the trend of China’s fta approach to investment concerning malleability? Is China a rule follower, shaker or maker? How may China approach the Regional Comprehensive Economic Partnership (RCEP) regarding investment? It argues first that the malleability will probably expand from investment protection to investment liberalization. China converges with deep ftas regarding investment protection and may incrementally move to investment liberalization. Second, increased malleability of China’s ftas exists in regulatory autonomy and investor-state dispute settlement. Third, China is likely to be …

Youth Workers' Use Of Facebook For Mediated Pastoralism With Juvenile Delinquents And Youths-At-Risk, Sun Sun Lim

Research Collection College of Integrative Studies

Youth work seeks to rehabilitate juvenile delinquents for re-entry into mainstream society and to prevent youthsat-risk from falling into delinquency, thus necessitating that youth workers assiduously monitor their clients. With the avid use of social media by youths, youth workers must also adopt these communication platforms to reach out to their young clients. Drawing from interviews with youth workers, this study analyses how they use Facebook to communicate with their clients and monitor their activities. Surveillance forms a key thrust of youth workers' professional use of Facebook, enhancing their ability to oversee these youths' personal development for the purposes of …

Board Independence As A Panacea To Tunneling? An Empirical Study Of Related Party Transactions In Hong Kong And Singapore, Christopher C. H. Chen, Wai Yee Wan, Wei Zhang Oct 2017

Board Independence As A Panacea To Tunneling? An Empirical Study Of Related Party Transactions In Hong Kong And Singapore, Christopher C. H. Chen, Wai Yee Wan, Wei Zhang

Research Collection Yong Pung How School Of Law

This article examines the effect of imposing higher board independence requirements on private benefit extraction by corporate management or controlling shareholders in Hong Kong and Singapore. This article shows that higher board independence negatively correlates with fewer related-party transactions (RPT), though in a nonlinear relationship with the marginal effect of higher board independence diminished. However, we find no clear causal effect of Hong Kong's imposition of a minimum board independence threshold in 2012 on reducing tunneling. Our data also show that higher concentration of ownership might not be associated with more tunneling by RPTs. Overall, this research lends support to …

Lord Denning’S Influence On Contract Formation In Singapore: An Overdue Demise?, Chia Ming Lee, Kenny Chng Oct 2017

Lord Denning’S Influence On Contract Formation In Singapore: An Overdue Demise?, Chia Ming Lee, Kenny Chng

Research Collection Yong Pung How School Of Law

In a series of inconsistent decisions by the Singapore courts on contract formation in continuing negotiations cases, Lord Denning’s broad approach—which does away with the traditional offer and acceptance analysis—appears to have been simultaneously adopted and rejected. This article suggests that the continued uncertainty in Singapore regarding the scope of application of the traditional approach and Lord Denning’s approach arises from a conflation of both as being substantially similar. This article further argues that both approaches are conceptually and practically distinct. A better way forward for Singapore law in the area of contract formation in continuing negotiations cases, having regard …

The Essence Of Luxury: An Asian Perspective: Lvmh-Smu Luxury Research Conference 2016, Srinivas K. Reddy, Jin K. Han

Research Collection Lee Kong Chian School Of Business

A number of developments in the luxury market have been attributed to the arrival of luxury products in Asian markets. The modernisation of Japan some decades back paved the way for a growing trend towards imbibing western lifestyles in Asia. Japan’s economic success after the Second World War was a key factor responsible for the introduction of luxury marketing in Asia. In the 1970’s, Japanese tourist-shoppers became a noticeable phenomenon in Europe. The European luxury houses were quick to recognise the opportunity and began setting up branches and luxury outlets in Japan. The Japanese were not only the driving force …

The Relentless Pursuit Of University Rankings Is Creating A Two-Track System, Eng Fong Pang, Linda Lim Oct 2017

The Relentless Pursuit Of University Rankings Is Creating A Two-Track System, Eng Fong Pang, Linda Lim

Research Collection Lee Kong Chian School Of Business

Global university rankings constructed mainly by Western commercial media outlets,like this week’s Quacquarelli Symonds (QS) Asia University Rankings, seem to be a perennial sourceof interest in Singapore.Yet, rankings have well-known limitations.The Ministry of Education (MOE) and university leaders frequently deny that they motivate policy orare a basis for institutional evaluation. But they do provide a convenient way to ascertain ifuniversities meet our aspirations for world-class status.At the same time, because rankings tend to emphasise research publications of global significance,there is some skepticism among academics and the general public everywhere of their value to localcommunities.
