China’S New Law On Exploration And Exploitation Of Resources In The International Seabed Area Of 2016, Nengye Liu, Rakhyun Kim Jan 2016

China’S New Law On Exploration And Exploitation Of Resources In The International Seabed Area Of 2016, Nengye Liu, Rakhyun Kim

Research Collection Yong Pung How School Of Law

Despite its rich metallic mineral resources on land,1 the People’s Republic of China (China) has been actively exploring for deep seabed minerals in the international seabed area (the Area).2 The legal framework is provided by the United Nations Convention on the Law of the Sea (LOSC).3 China and the Russian Federation are the only States currently sponsoring exploration of all three types of deep seabed mineral deposit in the Area (polymetallic nodules in the Clarion-Clipperton Fracture Zone, seafloor massive sulphides in the South West Indian Ridge, the Central Indian Ridge, and the Mid-Atlantic Ridge, and cobalt-rich ferromanganese crusts in the …

A Tale Of Two Option Markets: Pricing Kernels And Volatility Risk, Zhaogang Song, Dacheng Xiu Jan 2016

A Tale Of Two Option Markets: Pricing Kernels And Volatility Risk, Zhaogang Song, Dacheng Xiu

Research Collection Lee Kong Chian School Of Business

Using both S&P 500 option and recently introduced VIX option prices, we study pricing kernels and their dependence on multiple volatility factors. We first propose nonparametric estimates of marginal pricing kernels, conditional on the VIX and the slope of the variance swap term structure. Our estimates highlight the state-dependence nature of the pricing kernels. In particular, conditioning on volatility factors, the pricing kernel of market returns exhibit a downward sloping shape up to the extreme end of the right tail. Moreover, the volatility pricing kernel features a striking U-shape, implying that investors have high marginal utility in both high and …

The Word Outside And The Pictures In Our Heads: Contingent Framing Effects Of Labels On Health Policy Preferences By Political Ideology, Sungjong Roh, Jeff Niederdeppe Jan 2016

The Word Outside And The Pictures In Our Heads: Contingent Framing Effects Of Labels On Health Policy Preferences By Political Ideology, Sungjong Roh, Jeff Niederdeppe

Research Collection Lee Kong Chian School Of Business

This study uses data from systematic Web image search results and two randomized survey experiments to analyze how frames commonly used in public debates about health issues, oper- ationalized here as alternative word choices, influence public support for health policy reforms. In Study 1, analyses of Bing (N = 1,719), Google (N = 1,872), and Yahoo Images (N = 1,657) search results suggest that the images returned from the search query “sugar-sweetened beverage” are more likely to evoke health-related concepts than images returned from a search query about “soda.” In contrast, “soda” search queries were more likely to incorporate brand-related …

Robust Information Cascade With Endogenous Ordering, Yi Zhang Jan 2016

Robust Information Cascade With Endogenous Ordering, Yi Zhang

Research Collection School Of Economics

We analyze a sequential decision model with endogenous ordering in which decision makers are allowed to choose the time of acting (exercising a risky investment option) or waiting. We show the existence of a unique symmetric equilibrium and characterize information cascade under endogenous ordering. Further, if there are two or more risky investment options, individuals tend to wait longer with competition. Hence, we could end up with a dilemma: more options might be worse.

New Distribution Theory For The Estimation Of Structural Break Point In Mean, Liang Jiang, Xiaohu Wang, Jun Yu Jan 2016

New Distribution Theory For The Estimation Of Structural Break Point In Mean, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

Based on the Girsanov theorem, this paper first obtains the exact distribution of the maximum likelihood estimator of structural break point in a continuous time model. The exact distribution is asymmetric and tri-modal, indicating that the estimator is seriously biased. These two properties are also found in the finite sample distribution of the least squares estimator of structural break point in the discrete time model. The paper then builds a continuous time approximation to the discrete time model and develops an in-fill asymptotic theory for the least squares estimator. The obtained in-fill asymptotic distribution is asymmetric and tri-modal and delivers …

Meritocracy Voting: Measuring The Unmeasurable, Peter C. B. Phillips Jan 2016

Meritocracy Voting: Measuring The Unmeasurable, Peter C. B. Phillips

Research Collection School Of Economics

Learned societies commonly carry out selection processes to add new fellows to an existing fellowship. Criteria vary across societies but are typically based on subjective judgments concerning the merit of individuals who are nominated for fellowships. These subjective assessments may be made by existing fellows as they vote in elections to determine the new fellows or they may be decided by a selection committee of fellows and officers of the society who determine merit after reviewing nominations and written assessments. Human judgment inevitably plays a central role in these determinations and, notwithstanding its limitations, is usually regarded as being a …

Shrinkage Estimation Of Dynamic Panel Data Models With Interactive Fixed Effects, Xun Lu, Liangjun Su Jan 2016

Shrinkage Estimation Of Dynamic Panel Data Models With Interactive Fixed Effects, Xun Lu, Liangjun Su

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 (2009) and Moon and Weidner (2015), 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 zero. …

Semiparametric Estimation Of Partially Linear Dynamic Panel Data Models With Fixed Effects, Liangjun Su, Yonghui Zhang Jan 2016

Semiparametric Estimation Of Partially Linear Dynamic Panel Data Models With Fixed Effects, Liangjun Su, Yonghui Zhang

Research Collection School Of Economics

In this paper, we study a partially linear dynamic panel data model with fixed effects, where either exogenous or endogenous variables or both enter the linear part, and the lagged-dependent variable together with some other exogenous variables enter the nonparametric part. Two types of estimation methods are proposed for the first-differenced model. One is composed of a semiparametric GMM estimator for the finite-dimensional parameter θ and a local polynomial estimator for the infinite-dimensional parameter m based on the empirical solutions to Fredholm integral equations of the second kind, and the other is a sieve IV estimate of the parametric and …

Inference In Near-Singular Regression, Peter C. B. Phillips Jan 2016

Inference In Near-Singular Regression, Peter C. B. Phillips

Research Collection School Of Economics

This paper considers stationary regression models with near-collinear regressors. Limit theory is developed for regression estimates and test statistics in cases where the signal matrix is nearly singular in finite samples and is asymptotically degenerate. Examples include models that involve evaporating trends in the regressors that arise in conditions such as growth convergence. Structural equation models are also considered and limit theory is derived for the corresponding instrumental variable (IV) estimator, Wald test statistic, and overidentification test when the regressors are endogenous. It is shown that near-singular designs of the type considered here are not completely fatal to least squares …

Hot Property In New Zealand: Empirical Evidence Of Housing Bubbles In The Metropolitan Centres, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips Jan 2016

Hot Property In New Zealand: Empirical Evidence Of Housing Bubbles In The Metropolitan Centres, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips

Research Collection School Of Economics

Using recently developed statistical methods for testing and dating exuberant behaviour in asset prices we document evidence of episodic bubbles in the New Zealand property market over the past two decades. The results show clear evidence of a broad-based New Zealand housing bubble that began in 2003 and collapsed over mid-2007 to early 2008 with the onset of the worldwide recession and the financial crisis. New methods of analysing market contagion are also developed and are used to examine spillovers from the Auckland property market to the other metropolitan centres. Evidence from the latest data reveals that the greater Auckland …

Audience Segmentation For Campaign Design: Addressing Climate Change In Singapore, Benjamin H. Detenber, Sonny Rosenthal, Youqing Liao, Shirley S. Ho Jan 2016

Audience Segmentation For Campaign Design: Addressing Climate Change In Singapore, Benjamin H. Detenber, Sonny Rosenthal, Youqing Liao, Shirley S. Ho

Research Collection College of Integrative Studies

A nationally representative telephone survey (n = 1,006) was conducted to understand how different groups of Singaporeans regard the issue of climate change and their inclination toward action in dealing with it. We measured attitudes, knowledge, and perceptions of the problem of climate change and the role of various stakeholders in addressing it. The data were subjected to a latent class analysis to produce three distinctive segments of the population: the concerned, the disengaged, and the passive. These segments stand in contrast to those discovered in the United States, Australia, Germany, and India and suggest different strategies for public engagement …

3for2: Realizing Spatial, Material, And Energy Savings Through Integrated Design, Arno Schlueter, Adam Rysanek, Clayton Miller, Jovan Pantelic, Forrest Meggers, Matthias Mast, Marcel Bruelisauer, Chen Kian Wee

Research Collection College of Integrative Studies

As the world adapts to dual trends of climate change and urbanization, tall office buildings in hot and humid climate zones near the equator are among the prime candidates for a significant change in design approach. Though many individualized improvements to operating systems, envelopes and material selections have been introduced in recent years, it is generally agreed a holistic approach is needed to truly capitalize on the smaller-scale innovations. With a focus on reducing the necessary size of the services plenum, in this paper, an alternative paradigm for the optimization of space, material, and energy use in buildings is presented: …

A Comparison Of Fundamental Network Formation Principles Between Offline And Online Friends On Twitter, Felicia Natali, Feida Zhu Jan 2016

A Comparison Of Fundamental Network Formation Principles Between Offline And Online Friends On Twitter, Felicia Natali, Feida Zhu

Research Collection School Of Computing and Information Systems

We investigate the differences between how some of the fundamental principles of network formation apply among offline friends and how they apply among online friends on Twitter. We consider three fundamental principles of network formation proposed by Schaefer et al.: reciprocity, popularity, and triadic closure. Overall, we discover that these principles mainly apply to offline friends on Twitter. Based on how these principles apply to offline versus online friends, we formulate rules to predict offline friendship on Twitter. We compare our algorithm with popular machine learning algorithms and Xiewei’s random walk algorithm. Our algorithm beats the machine learning algorithms on …

Ideas, Interests And Practical Authority In Reform Politics: Decentralization Reform In South Korea In The 2000s, Yooil Bae Jan 2016

Ideas, Interests And Practical Authority In Reform Politics: Decentralization Reform In South Korea In The 2000s, Yooil Bae

Research Collection School of Social Sciences

This paper explains the reason why the hitherto statist country, Korea, has carried out significant decentralization since the 2000s. In explaining the motivation for decentralization, extant literature has focused on the role of parties, bureaucratic politics, democratization, or territorial interests. Yet there is still limited explanation of how the decentralization laws in Korea could be successfully passed in the 2000s, while cental stakeholders still persisted. By tracing the process of decentralization reform in the 2000s, this article demonstrates how structural factors created favourable circumstances and discursive background for institutional change, and how the idea of decentralization, through the idea diffusion …

How The Eu Learned To Love Sanctions, Clara Portela Jan 2016

How The Eu Learned To Love Sanctions, Clara Portela

Research Collection School of Social Sciences

It is only recently that the European public has woken up to the sue of sanctions in EU foreign policy, though they have been employed since the early 1980s. They became more frequent following the 1992 establishment of the Common Foreign and Security Policy (CFSP), the EU's intergovernmental forum for foreign policy coordination.

In A Funk Over Trump, David Chan Jan 2016

In A Funk Over Trump, David Chan

Research Collection School of Social Sciences

Cynicism, for instance about startling turns in global affairs, can be toxic. A dose of healthy scepticism is a much better approach. Trust is an important foundation in interactions between people, and this applies in relationships between friends, employee and employer, or citizens and the government. At the government level, recent surprise world events, such as Brexit, when Britons voted to leave the European Union, and last week's election of anti-establishment figure Donald Trump to the United States presidency, suggest a disruption of that foundation of trust. One challenge from such a turn of events is the rise of cynicism. …

Public Vs. Private Schooling As A Route To Universal Basic Education: A Comparison Of China And India, William C. Smith, Devin K. Joshi Jan 2016

Public Vs. Private Schooling As A Route To Universal Basic Education: A Comparison Of China And India, William C. Smith, Devin K. Joshi

Research Collection School of Social Sciences

This article examines whether focusing primarily on public schooling can lead to more rapid achievement of universal basic education (UBE) than relying on a mixture of public and private schooling. Through a structured, focused comparison, we find China's greater emphasis on public schooling has contributed to higher enrollment, attendance, graduation rates, gender parity, and proportion of students entering higher education than India, the country with the world's largest private sector in primary and secondary education. This comparison suggests that greater emphasis on public schooling in developing countries may lead to more rapid UBE attainment than encouraging privatization.

Achieving Regulatory Excellence In The Agri-Food Biotechnology Sector: Building Policy Capacity, Michael Howlett, Ishani Mukherjee Jan 2016

Achieving Regulatory Excellence In The Agri-Food Biotechnology Sector: Building Policy Capacity, Michael Howlett, Ishani Mukherjee

Research Collection School of Social Sciences

What capacities are needed on the part of policymakers in areas such as the agri-food biotechnology sector in order to attain excellence at the individual, organisational and systemic levels of regulatory operation? To address this question, this paper draws upon work recently carried out on regulatory excellence by the Penn Programme on Regulation and couples it with recent studies on how to build policy capacity. Derived from a multi-jurisdiction, multi-sector review of regulation, the Penn programme identified three core areas or `pillars' of regulatory excellence - namely, stellar competence, empathic engagement and utmost integrity -which reflect the kinds of individual …

Of Minds, Morals, And Methods: Combining Moral Meteorology And Disaster Relief In Historiography Of China’S Disaster Management, Wee-Kiat Lim Dec 2015

Of Minds, Morals, And Methods: Combining Moral Meteorology And Disaster Relief In Historiography Of China’S Disaster Management, Wee-Kiat Lim

CCX Research

In this working paper, I argue that disaster management in high Qing period can be better understood by simultaneously considering the historiographies of how governing elites understood disasters at the metaphysical level and the administration of disaster relief. During High Qing late imperial China, the regime encountered rapid changes in population, economy, and environment. Following how environmental historian Mark Elvin describes the prevalent ideology that guided Chinese governing elites on implicating human conduct with the manifestation of disasters as “moral meteorology”, I link it to the granary system so as to underscore how these two related but separate streams of …

Capstone Projects Mining System For Insights And Recommendations, Melvrivk Aik Chun Goh, Swapna Gottipati, Venky Shankararaman Dec 2015

Capstone Projects Mining System For Insights And Recommendations, Melvrivk Aik Chun Goh, Swapna Gottipati, Venky Shankararaman

Research Collection School Of Computing and Information Systems

In this paper, we present a classification based system to discover knowledge and trends in higher education students’ projects. Essentially, the educational capstone projects provide an opportunity for students to apply what they have learned and prepare themselves for industry needs. Therefore mining such projects gives insights of students’ experiences as well as industry project requirements and trends. In particular, we mine capstone projects executed by Information Systems students to discover patterns and insights related to people, organization, domain, industry needs and time. We build a capstone projects mining system (CPMS) based on classification models that leverage text mining, natural …

7 'Pc' Ways To Make People-Centric Policies, David Chan Dec 2015

7 'Pc' Ways To Make People-Centric Policies, David Chan

Research Collection School of Social Sciences

If asked to describe 2015 for Singapore, I would summarise it as "a people-centric year". For just about everyone - politicians, civil servants, community leaders, academics, journalists, social activists or the public itself - the attention was centred on issues that matter to the people. It may seem obvious that being people-centric should characterise how Singapore goes about things. But when people-centricity is driven by populist concerns or political correctness, the outcomes can be self-defeating at best and disastrous at worst. It is important that individuals, communities and the Government, who adopt the ideal of being people-centric, know what it …

Moocs And Crowdsourcing: Massive Courses And Massive Resources, John Prpić, James Melton, Araz Taeihagh, Terry Anderson Dec 2015

Moocs And Crowdsourcing: Massive Courses And Massive Resources, John Prpić, James Melton, Araz Taeihagh, Terry Anderson

Research Collection School of Social Sciences

Premised upon the observation that MOOC and crowdsourcing phenomena share several important characteristics, including IT mediation, large-scale human participation, and varying levels of openness to participants, this work systematizes a comparison of MOOC and crowdsourcing phenomena along these salient dimensions. In doing so, we learn that both domains share further common traits, including similarities in IT structures, knowledge generating capabilities, presence of intermediary service providers, and techniques designed to attract and maintain participant activity. Stemming directly from this analysis, we discuss new directions for future research in both fields and draw out actionable implications for practitioners and researchers in both …

Economic Status And Old-Age Health In Poverty-Stricken Myanmar, Bussarawan Teerawichitchainan, John Knodel Dec 2015

Economic Status And Old-Age Health In Poverty-Stricken Myanmar, Bussarawan Teerawichitchainan, John Knodel

Research Collection School of Social Sciences

Objective: We examine the association between poverty, economic inequality, and health among elderly in Myanmar. Method: We analyze 2012 data from Myanmar’s first representative survey of older adults to investigate how health indicators vary across wealth quintiles as measured by household possessions and housing quality. Results: Poverty and poor health are pervasive. Self-assessed health, sensory impairment, and functional limitation consistently improve with higher wealth levels regardless of socio-demographic controls. Differentials in self-rated health and sensory impairment between the bottom and second quintiles are clearly evident, suggesting that relative economic inequality matters even among very poor elders and that a small …

The Situation Of Thailand’S Older Population: An Update Based On The 2014 Survey Of Older Persons In Thailand, John Knodel, Bussarawan Teerawichitchainan, Vipan Prachuabmoh, Wiraporn Pothisiri

Research Collection School of Social Sciences

Population ageing and the well-being of older persons are major emerging challenges for families, communities and government in Thailand as in much of Asia. The Thai government has been giving very serious attention to ageing issues. This was clearly indicated by the adoption of the Second National Plan for Older Persons covering 2002-2021, the prominence of ageing issues in the 2012-16 National Economic and Social Development Plan, and a 2015 establishment of the Department of Older Persons with expanded authority to carry out programs to support elderly Thais. Furthermore, the Old Age Allowance program was expanded in 2009 into a …
