Random Dictatorship Domains, Shurojit Chatterji, Arunava Sen, Huaxia Zeng Jul 2014

Random Dictatorship Domains, Shurojit Chatterji, Arunava Sen, Huaxia Zeng

Research Collection School Of Economics

A domain of preference orderings is a random dictatorship domain if every strategy-proof random social choice function satisfying unanimity defined on the domain is a random dictatorship. Gibbard (1977) showed that the universal domain is a random dictatorship domain. We ask whether an arbitrary dictatorial domain is a random dictatorship domain and show that the answer is negative by constructing dictatorial domains that admit anonymous, unanimous, strategy-proof random social choice functions which are not random dictatorships. Our result applies to the constrained voting model. Lastly, we show that substantial strengthenings of linked domains (a class of dictatorial domains introduced in …

Dynamic Pricing In The Singapore Condominium Market, Eric Fesselmeyer, Haoming Liu Jul 2014

Dynamic Pricing In The Singapore Condominium Market, Eric Fesselmeyer, Haoming Liu

Research Collection College of Integrative Studies

Dynamic pricing strategies are likely an important consideration of Singapore condominium developers because of the durability of condominiums, price transparency, and the long sales period. While we do not observe any systematic relationship between the new sale prices and time of purchase, we do find that quality-adjusted price increases and the quality of units purchased decreases over the new sale period. These results suggest that condominium developers allow early buyers to purchase high quality units at discounted prices but do not extend the price discount to later buyers of low quality units.

Sequential Investment, Hold-Up, And Ownership Structure, Juyuan Zhang, Yi Zhang Jul 2014

Sequential Investment, Hold-Up, And Ownership Structure, Juyuan Zhang, Yi Zhang

Research Collection School Of Economics

We construct a sequential investment model to investigate individual firms’ strategic choices of organizational forms when outsourcing their intermediate products. Our results indicate that as a result of the encouragement effect of sequential complementary investments, sequential investment alleviates the underinvestment caused by the hold-up problem. Thereafter, we analyze the impact of sequential investment on the choice of ownership structure. We show that contrary to the result of the standard property rights theory, strictly complementary assets could be owned separately.

Singapore’S Competitiveness At Risk, Augustine H. H. Tan Jul 2014

Singapore’S Competitiveness At Risk, Augustine H. H. Tan

Research Collection School Of Economics

Singapore’s disappointing second-quarter growth of 2.1 per cent compared with the same period last year has raised concerns about the impact of economic restructuring. When compared with the last quarter, growth even dipped 0.8 per cent. At the same time, productivity performance has been dismal. After rising by 2.2 per cent in 2011, productivity dropped by 1.4 per cent in 2012 and another 0.2 per cent last year.

Lifetime Lexical Variation In Social Media, Lizi Liao, Jing Jiang, Ying Ding, Heyan Huang, Ee Peng Lim Jul 2014

Lifetime Lexical Variation In Social Media, Lizi Liao, Jing Jiang, Ying Ding, Heyan Huang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

As the rapid growth of online social media attracts a large number of Internet users, the large volume of content generated by these users also provides us with an opportunity to study the lexical variation of people of different ages. In this paper, we present a latent variable model that jointly models the lexical content of tweets and Twitter users’ ages. Our model inherently assumes that a topic has not only a word distribution but also an age distribution. We propose a Gibbs-EM algorithm to perform inference on our model. Empirical evaluation shows that our model can learn meaningful age-specific …

Three Essays On Nonstationary Time Series Analysis, Ye Chen Jun 2014

Three Essays On Nonstationary Time Series Analysis, Ye Chen

Dissertations and Theses Collection (Open Access)

Financial and macroeconomic time series data are often nonstationary. My dissertation consists of three essays concerning time series models with nonstationarity. Chapter 1 develops a new jackknife estimator for nonstationary autoregressive model. The remaining two chapters explore the restricted maximum likelihood (REML hereafter) estimation and the restricted maximum likelihood based likelihood ratio test (RLRT hereafter) in predictive regression. Chapter 1 proposes an improved jackknife estimator of the persistence parameter that works for both the discrete time unit root model and the continuous time unit root model. Maximum likelihood estimation of the persistence parameter in the discrete time unit root model …

Does Latitude Hurt While Longitude Kills? Geographical And Temporal Separation In A Large Scale Software Development Project, Patrick Wagstrom, Subhajit Datta Jun 2014

Does Latitude Hurt While Longitude Kills? Geographical And Temporal Separation In A Large Scale Software Development Project, Patrick Wagstrom, Subhajit Datta

Research Collection School Of Computing and Information Systems

Distributed software development allows firms to leverage cost advantages and place work near centers of competency. This distribution comes at a cost -- distributed teams face challenges from differing cultures, skill levels, and a lack of shared working hours. In this paper we examine whether and how geographic and temporal separation in a large scale distributed software development influences developer interactions. We mine the work item trackers for a large commercial software project with a globally distributed development team. We examine both the time to respond and the propensity of individuals to respond and find that when taken together, geographic …

Online Community Transition Detection, Biying Tan, Feida Zhu, Qiang Qu, Siyuan Liu Jun 2014

Online Community Transition Detection, Biying Tan, Feida Zhu, Qiang Qu, Siyuan Liu

Research Collection School Of Computing and Information Systems

Mining user behavior patterns in social networks is of great importance in user behavior analysis, targeted marketing, churn prediction and other applications. However, less effort has been made to study the evolution of user behavior in social communities. In particular, users join and leave communities over time. How to automatically detect the online community transitions of individual users is a research problem of immense practical value yet with great technical challenges. In this paper, we propose an algorithm based on the Minimum Description Length (MDL) principle to trace the evolution of community transition of individual users, adaptive to the noisy …

Socio-Physical Analytics: Challenges & Opportunities, Archan Misra, Kasthuri Jayarajah, Shriguru Nayak, Philips Kokoh Prasetyo, Ee-Peng Lim Jun 2014

Socio-Physical Analytics: Challenges & Opportunities, Archan Misra, Kasthuri Jayarajah, Shriguru Nayak, Philips Kokoh Prasetyo, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

In this paper, we argue for expanded research into an area called Socio-Physical Analytics, that focuses on combining the behavioral insight gained from mobile-sensing based monitoring of physical behavior with the inter-personal relationships and preferences deduced from online social networks. We highlight some of the research challenges in combining these heterogeneous data sources and then describe some examples of our ongoing work (based on real-world data being collected at SMU) that illustrate two aspects of socio-physical analytics: (a) how additional demographic and online analytics based attributes can potentially provide better insights into the preferences and behaviors of individuals or groups …

Crowdsourcing The Policy Cycle, John Prpić, Araz Taeihagh, James Melton Jun 2014

Crowdsourcing The Policy Cycle, John Prpić, Araz Taeihagh, James Melton

Research Collection School of Social Sciences

Crowdsourcing is beginning to be used for policymaking. The “wisdom of crowds” [Surowiecki 2005], and crowdsourcing [Brabham 2008], are seen as new avenues that can shape all kinds of policy, from transportation policy [Nash 2009] to urban planning [Seltzer and Mahmoudi 2013], to climate policy. In general, many have high expectations for positive outcomes with crowdsourcing, and based on both anecdotal and empirical evidence, some of these expectations seem justified [Majchrzak and Malhotra 2013]. Yet, to our knowledge, research has yet to emerge that unpacks the different forms of crowdsourcing in light of each stage of the well-established policy cycle. …

Priming Bush (Vs. Obama) Increases Liking Of American Brands: The Role Of Intersubjectively Important Values, Letty Y. Y. Kwan, Chi-Yue Chiu, Angela K. Y. Leung Jun 2014

Priming Bush (Vs. Obama) Increases Liking Of American Brands: The Role Of Intersubjectively Important Values, Letty Y. Y. Kwan, Chi-Yue Chiu, Angela K. Y. Leung

Research Collection School of Social Sciences

Past research has shown that exposure to cultural symbols can influence personal preferences. The present research extends this finding by showing that cultural symbols acquire their cultural significance in part through their associations with intersubjectively important values—values that are perceived to be prevalent in the culture. In addition, cultural symbols can influence personal preferences through the activation of perceived normative preferences. In Study 1, perceived liking of Bush among Americans was linked to the perceived popularity of intersubjectively important values in the USA. In Study 2, both priming Bush and personal endorsement of intersubjectively important values increased Americans' liking of …

Competing Logics Of Commemoration: Cosmopolitanism And Nationalism In East Asia's History Problem, Hiro Saito, Yoko Wang Jun 2014

Competing Logics Of Commemoration: Cosmopolitanism And Nationalism In East Asia's History Problem, Hiro Saito, Yoko Wang

Research Collection School of Social Sciences

Recent studies in collective memory point to the emergence of cosmopolitan commemoration that takes humanity, rather than nationality, as a primary frame of reference. But these studies have yet to specify how cosmopolitan commemoration emerges and articulates with existing nationalist commemoration. To solve this problem, we examine the “history problem” between Japan and South Korea by focusing on how relevant political and civic actors negotiated cosmopolitanism and nationalism in commemorating Japan’s past colonial rule and wartime atrocities. In light of our historical analysis, we argue that a synthesis of theories of institutional logics and social movements is useful in illuminating …

The Elements Of Effective Program Design: A Two-Level Analysis, Michael Howlett, Ishani Mukherjee, Jeremy Rayner Jun 2014

The Elements Of Effective Program Design: A Two-Level Analysis, Michael Howlett, Ishani Mukherjee, Jeremy Rayner

Research Collection School of Social Sciences

Policy and program design is a major theme of contemporary policy research, aimed at improving the understanding of how the processes, methods and tools of policy-making are employed to better formulate effective policies and pro-grams, and to understand the reasons why such designs are not forthcoming. However while many efforts have been made to evaluate policy design, less work has focused on program designs. This article sets out to fill this gap in knowledge of design practices in policy-making. It outlines the nature of the study of policy design with a particular focus on the nature of programs and the …

A Seed Dataset For A Public, Temporal Data Repository For Energy Informatics Research On Commercial Building Performance, Clayton Miller, Zoltán Nagy, Arno Schlueter Jun 2014

A Seed Dataset For A Public, Temporal Data Repository For Energy Informatics Research On Commercial Building Performance, Clayton Miller, Zoltán Nagy, Arno Schlueter

Research Collection College of Integrative Studies

Building performance research using various informatics techniques has progressed extensively in the last twenty years by advancing the fields of automated fault detection and diagnostics (AFDD), commissioning, data mining, and visualization for commercial buildings. Despite this effort, it has been difficult to understand the effectiveness of different approaches as compared to each other as there is a lack of general, public benchmarking datasets for this industry. We propose a repository in which researchers can release their detailed raw datasets for the purpose of repeatability, benchmarking, and utilization by other researchers. We start this effort through the public release of a …

Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh Jun 2014

Of Accessibility And Applicability: How Heat-Related Primes Affect Belief In “Global Warming” And “Climate Change”, Jonathon P. Schuldt, Sungjong Roh

Research Collection Lee Kong Chian School Of Business


Research shows that exposure to heat-related cues (e.g., warm temperatures, “fry” and “boil”) influences the belief that global warming exists and poses a serious threat to humans. Drawing on social-cognitive principles of concept accessibility and applicability, we hypothesized that these effects may depend on how the issue is framed, given that heat-related concepts are more compatible with “global warming” than “climate change.” Exploring this possibility, we asked campus passersby about their belief in global warming or climate change shortly after a real-life unseasonably cold weather event (i.e., snowfall during Spring; Study 1). A controlled Web experiment …

Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho Jun 2014

Parasocial Relationship Via Reality Tv And Social Media: Its Implications For Celebrity Endorsement, Siyoung Chung, Hichang Cho

Research Collection Lee Kong Chian School Of Business

The purpose of this study was to explore the ways in which audiences build parasocial relationships with media characters via reality TV and social media, and its implications for celebrity endorsement and purchase intentions. Using an online survey, this study collected 401 responses from the Korean Wave fans in Singapore. The results showed that reality TV viewing and SNS use to interact with media characters were positively associated with parasocial relationships between media characters and viewers. Parasocial relationships, in turn, were positively associated with the viewers’ perception of endorser and brand credibility, and purchase intention of the brand endorsed by …

Climate Change And Management: From The Editors, Jennifer Howard-Grenville, Simon J. Buckle, Brian J. Hoskins, Gerard George

Research Collection Lee Kong Chian School Of Business

Climate change is one of the greatest challenges we confront in the 21st century. On current trends, by the end of the century, the warming effect of our greenhouse gas emissions will have taken us far away from pre-industrial climatic conditions. In fact, our climate will be as different from pre-industrial conditions as it was when the Earth emerged from the last ice age some 20,000 years ago. In other words, just over 200 years of human and industrial activity will have wrought fundamental change to our climate system. The rise of organizations and industrialized production has set us on …

Adaptive Nonparametric Regression With Conditional Heteroskedasticity, Sainan Jin, Liangjun Su, Zhijie Xiao Jun 2014

Adaptive Nonparametric Regression With Conditional Heteroskedasticity, Sainan Jin, Liangjun Su, Zhijie Xiao

Research Collection School Of Economics

Vector Autoregression (VAR) has been a standard empirical tool used in macroeconomics and finance. In this paper we discuss how to compare alternative VAR models after they are estimated by Bayesian MCMC methods. In particular we apply a robust version of deviance information criterion (RDIC) recently developed in Li et al. (2014b) to determine the best candidate model. RDIC is a better information criterion than the widely used deviance information criterion (DIC) when latent variables are involved in candidate models. Empirical analysis using US data shows that the optimal model selected by RDIC can be different from that by DIC.

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu Jun 2014

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu

Research Collection School Of Economics

The paper proposes a self-exciting asset pricing model that takes into account cojumps between prices and volatility and self-exciting jump clustering. We employ a dence of self-exciting jump clustering since the 1987 market crash, and its importance Bayesian learning approach to implement real time sequential analysis. We find evidence of self-exciting jump clustering since the 1987 market crash, and its importance becomes more obvious at the onset of the 2008 global financial crisis. It is found that learning affects the tail behaviors of the return distributions and has important implications for risk management, volatility forecasting and option pricing.

Managing Private Vehicles In Asian Cities, Sock-Yong Phang Jun 2014

Managing Private Vehicles In Asian Cities, Sock-Yong Phang

Research Collection School Of Economics

Asia's rapid urbanization and growing incomes have resulted in a corresponding booming market in motor vehicle sales. In 2013, an estimated 18 million new passenger cars were sold in China. Motor vehicle users generate congestion, pollution, accidents, noise and road damage. Yet, in most cities motor vehicle users often do not pay the full social costs and are therefore implicitly subsidized by non-users. According to the Tom Tom Traffic Index, which is based on GPS data, motorists in the worst congested cities in developed countries spend up to 40% more time for peak hour commutes. This level of delay is …

Is The Renminbi East Asia’S Dominant Reference Currency? A Reconsideration, Hwee Kwan Chow Jun 2014

Is The Renminbi East Asia’S Dominant Reference Currency? A Reconsideration, Hwee Kwan Chow

Research Collection School Of Economics

Recent empirical studies show that the Chinese currency renminbi is either becoming or has become a dominant reference currency in Asia. However, the high correlation between the US dollar and renminbi movements hampers the identification of their individual effects on the Asian currencies. In particular, the application of Frankel-Wei regressions to determine the weights of the US dollar and the (unorthogonalized) renminbi in the implicit currency baskets could suffer from endogeneity problems that produce an upward bias in renminbi’s estimated weight. This paper reviews the evidence by applying country-specific VAR models to daily exchange rate data from nine Asian economies …

Specification Sensitivity In Right‐Tailed Unit Root Testing For Explosive Behaviour, Peter C. B. Phillips, Shuping Shi, Jun Yu Jun 2014

Specification Sensitivity In Right‐Tailed Unit Root Testing For Explosive Behaviour, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

This article aims to provide some empirical guidelines for the practical implementation of right-tailed unit root tests, focusing on the recursive right-tailed ADF test of Phillips et al. (2011b). We analyze and compare the limit theory of the recursive test under different hypotheses and model specifications. The size and power properties of the test under various scenarios are examined and some recommendations for empirical practice are given. Some new results on the consistent estimation of localizing drift exponents are obtained, which are useful in assessing model specification. Empirical applications to stock markets illustrate these specification issues and reveal their practical …
