Testing Alphas In Conditional Time-Varying Factor Models With High Dimensional Assets, Shujie Ma, Wei Lan, Liangjun Su, Chih-Ling Tsai

Research Collection School Of Economics

For conditional time-varying factor models with high dimensional assets, this article proposes a high dimensional alpha (HDA) test to assess whether there exist abnormal returns on securities (or portfolios) over the theoretical expected returns. To employ this test effectively, a constant coefficient test is also introduced. It examines the validity of constant alphas and factor loadings. Simulation studies and an empirical example are presented to illustrate the finite sample performance and the usefulness of the proposed tests. Using the HDA test, the empirical example demonstrates that the FF three-factor model (Fama and French, 1993) is better than CAPM (Sharpe, 1964) …

Competition, Markups, And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade in a model with head-to-head competition using Chinese firm-level data from Economic Censuses in 1995 and 2004. We find a significant reduction in trade cost during this period, and total gains from such improved openness during this period is 7.1%. The gains are decomposed into a Ricardian component and two pro-competitive ones. The pro-competitive effects account for 20% of the total gains. Moreover, the total gains from trade are 13 − 31% larger than what would result from the formula provided by ACR (Arkolakis et al., 2012), which nests a …

Strong Consistency Of Spectral Clustering For Stochastic Block Models, Liangjun Su, Wuyi Wang, Yichong Zhang

Research Collection School Of Economics

In this paper we prove the strong consistency of several methods based on the spectral clustering techniques that are widely used to study the community detection problem in stochastic block models (SBMs). We show that under some weak conditions on the minimal degree, the number of communities, and the eigenvalues of the probability block matrix, the K-means algorithm applied to the eigenvectors of the graph Laplacian associated with its first few largest eigenvalues can classify all individuals into the true community uniformly correctly almost surely. Extensions to both regularized spectral clustering and degree-corrected SBMs are also considered. We illustrate the …

Singapore In The Global Value Chains, Pao-Li Chang, Tran Bao Phuong Nguyen

Research Collection School Of Economics

In this chapter, we analyze the participation of Singapore in the global value chains (GVC): how much of its gross exports are GVC-related trade, how downstream it is, and which countries are its key upstream and downstream trade partners. This is done at both the country aggregate and at the sector level. New formulas are proposed in the gross export decomposition framework of Koopman, Wang and Wei (2014) and Borin and Mancini (2017), to characterize a country/industry’s downstreamness in the GVC and the importance of each trade partner in its backward/forward linkages. Singapore is found to start off with a …

Rationalizable Incentives: Interim Implementation Of Sets In Rationalizable Strategies, Takashi Kunimoto, Roberto Serrano

Research Collection School Of Economics

This paper investigates rationalizable implementation of social choice sets (SCSs) in incomplete information environments. We identify rationalizable incentive compatibility (RIC) as its key condition, argue by means of example that RIC is strictly weaker than the standard Bayesian incentive compatibility (BIC), and show that RIC reduces to BIC when we only consider single-valued SCSs (i.e., social choice functions or SCFs). We next identify additional necessary conditions and, essentially closing the gap be-tween necessity and sufficiency, obtain a sufficiency result for rationalizable implementation in general environments. We also characterize a well-studied class of economic environments in which RIC is essentially the …

Political Financing Reform: Politics, Policies, And Patronage In Malaysia, Sebastian Carl Dettman, Edmund Terence Gomez

Research Collection School of Social Sciences

This article analyses the evolution of political finance reform debates in Malaysia, one of the world’s most durable electoral authoritarian regimes. While the reliance of the dominant party, UMNO, on unfettered resources remained unchanged, crises in Malaysia’s political environment allowed civil society actors to concretise abstract debates over reform into specific proposals. Drawing from interviews, public statements and observation, two distinct periods in this reform debate are analysed: after Najib Razak assumed power in 2009, following the unprecedented electoral success of the opposition during the 2008 general election; and after the 1MDB scandal broke in 2015. In both periods, civil …

Commentary: What Lies Ahead? Considering The Future Of A ‘New’ Vietnamese Higher Education, Yasmin Y. Ortiga

Research Collection School of Social Sciences

In this commentary, Ortiga discusses two main tensions in how the authors in this volume portray the future of Vietnamese higher education. The first tension is the issue of autonomy or how universities must redefine their purpose and role in Vietnamese society as the state loosens its monopoly over higher education. Meanwhile, the second tension is the issue of privatisation or whether for-profit corporations and private agencies should play an increasing role in providing higher education services in the country. In reflecting on the future, Ortiga compares the case of Vietnam to higher education systems in neighbouring countries like the …

Geography, Trade And Power-Law Phenomena, Pao-Li Chang, Wen-Tai Hsu

Research Collection School Of Economics

This article reviews interrelated power-law phenomena in geography and trade. Given the empirical evidence on the gravity equation in trade flows across countries and regions, its theoretical underpinnings are reviewed. The gravity equation amounts to saying that trade flows follow a power law in distance (or geographic barriers). It is concluded that in the environment with firm heterogeneity, the power law in firm size is the key condition for the gravity equation to arise. A distribution is said to follow a power law if its tail probability follows a power function in the distribution’s right tail. The second part of …

Model Selection For Explosive Models, Yubo Tao, Jun Yu

Research Collection School Of Economics

This chapter examines the limit properties of information criteria (such as AIC, BIC, and HQIC) for distinguishing between the unit-root (UR) model and the various kinds of explosive models. The explosive models include the local-to-unit-root model from the explosive side the mildly explosive (ME) model, and the regular explosive model. Initial conditions with different orders of magnitude are considered. Both the OLS estimator and the indirect inference estimator are studied. It is found that BIC and HQIC, but not AIC, consistently select the UR model when data come from the UR model. When data come from the local-to-unit-root model from …

China’S Regulatory Approach To The Sharing Economy: A Perspective On Ride-Hailing, Huiqin Jiang, Heng Wang

Research Collection Yong Pung How School Of Law

While the sharing economy brings significant social benefits in China, it comes with regulatory challenges that are novel and unpredictable. How should regulators handle these challenges? This paper offers fresh insights into the regulatory approach to the ride-hailing industry, the most comprehensively regulated sharing industry in China. A historical review identifies three regulatory approaches deployed to date: self-regulation, market-based regulation and government regulation. Self-regulation relies on the platforms with incentive to provide better service for greater profit, and to deal with sharing-specific challenges. Market-based regulation invites rivals to keep a watchful eye on other players, in order to enhance their …

Cross-Border Regulation Of Securities Markets In Asean, Wai Yee Wan

Research Collection Yong Pung How School Of Law

How does cross-border regulation of securities markets work in Association of South East Asian Nations (ASEAN)? How closely are the securities markets coordinated within ASEAN from the regulatory perspective? What is the optimal regulatory model of integration of securities markets that balances the economic benefits of integration and yet minimizes the risks of contagion and advances the state’s national goals? The issues posed by these questions are important against the background of strong growth of the Asian economies and Asian capital markets, and how the ASEAN states can take advantage of such growth to facilitate economic growth. According to the …

Article 152 Of The Singapore Constitution: The Past, Present, And Future Of Multiracial Recognition, Inclusion, And Accommodation, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

The bicentennial commemoration consists of a year-long series of events to mark the 200^th anniversary of the arrival of Sir Stamford Raffles in Singapore on 29 January 1819. The arrival of the British resulted in the creation of Singapore as a free port and marked the economic, physical, and social transformation of the island, which continues today. Yet, the irony is that the bicentennial commemoration also deliberately seeks to shed light and focus on a more distant past: The half-millennia before Singapore was colonialised and when Singapore was known as Temasek and seen as part of the Nusantara.

Land Of The Falling "Poison Pill" Understanding Defensive Measures In Japan On Their Own Terms, Alan K. Koh, Masafumi Nakahigashi, Dan W. Puchniak

Research Collection Yong Pung How School Of Law

Embraced by United States ("U.S.") managers in the 1980s as a lifeline in a sea of hostile takeovers, the poison pill fundamentally altered the trajectory of American corporate governance. When a hostile takeover wave seemed imminent in Japan in the mid-2000s, Japanese boards appeared to embrace this American invention with equal enthusiasm. Japan's experience should have been a ringing endorsement for the utility of American corporate governance solutions in foreign jurisdictions -but it was not to be. Japan's unique interpretation of the "poison pill" that was so eagerly adopted by Japanese companies in the mid-to-late 2000s has turned out to …

Spatial Multi-Objective Land Use Optimization Toward Livability Based On Boundary-Based Genetic Algorithm: A Case Study In Singapore, Kai Cao, Muyang Liu, Shu Wang, Mengqi Liu, Wenting Zhang, Qiang Meng, Bo Huang

Research Collection School Of Computing and Information Systems

In this research, the concept of livability has been quantitatively and comprehensively reviewed and interpreted to contribute to spatial multi-objective land use optimization modelling. In addition, a multi-objective land use optimization model was constructed using goal programming and a weighted-sum approach, followed by a boundary-based genetic algorithm adapted to help address the spatial multi-objective land use optimization problem. Furthermore, the model is successfully and effectively applied to the case study in the Central Region of Queenstown Planning Area of Singapore towards livability. In the case study, the experiments based on equal weights and experiments based on different weights combination have …

Emoco: Visual Analysis Of Emotion Coherence In Presentation Videos, Haipeng Zeng, Xingbo Wang, Aoyu Wu, Yong Wang, Quan Li, Alex Endert, Huamin Qu

Research Collection School Of Computing and Information Systems

Emotions play a key role in human communication and public presentations. Human emotions are usually expressed through multiple modalities. Therefore, exploring multimodal emotions and their coherence is of great value for understanding emotional expressions in presentations and improving presentation skills. However, manually watching and studying presentation videos is often tedious and time-consuming. There is a lack of tool support to help conduct an efficient and in-depth multi-level analysis. Thus, in this paper, we introduce EmoCo, an interactive visual analytics system to facilitate efficient analysis of emotion coherence across facial, text, and audio modalities in presentation videos. Our visualization system features …

Development Of An Overarching Transboundary Geospatial Framework : Selected Regimes In Perspective, Bryan Buxton-Barnor

World Maritime University Ph.D. Dissertations

In the maritime industry, a significant number of emerging and complex challenges occurring, has engaged limited attention and tenuous governance structures that can hardly deal with such complexities. Hence, the need for practitioners to seek innovative planning approaches for addressing such complexities, particularly the cumulative impacts on the marine environment. Such swelling effect, cannot be overemphasized in the Gulf of Guinea marine region which lies between Cape Lopez in Gabon and Cape Palmas in Liberia. This region, has a long history of conflicting marine uses and unresolved disputes. Prior to 2020, three adjacent nations in this region have engaged in …

Laterality Of Eye Use By Bottlenose (Tursiops Truncatus) And Rough-Toothed (Steno Bredanensis) Dolphins While Viewing Predictable And Unpredictable Stimuli, Malin Lilley, Amber J. De Vere, Deirdre Yeater

Psychology Faculty Publications

Laterality of eye use has been increasingly studied in cetaceans. Research supports that many cetacean species keep prey on the right side while feeding and preferentially view unfamiliar objects with the right eye. In contrast, the left eye has been used more by calves while in close proximity to their mothers. Despite some discrepancies across and within species, laterality of eye use generally indicates functional specialization of brain hemispheres in cetaceans. The present study aimed to examine laterality of eye use in bottlenose dolphins (Tursiops truncatus) and rough-toothed dolphins (Steno bredanensis) under managed care. Subjects were video-recorded through an underwater …

School of Medicine Publications

Following publication of our two articles [1, 2], a critique of the methodology of Phenotype-Genotype Many-to-Many Relations Analysis (PGMRA) [1, 3, 4] questioned the validity of our results from the perspective of polygenic risk scores (PRS) [5]. We appreciate the importance of these questions, and here provide a concise discussion of the assumptions and mathematical constraints of both approaches. We thank this commentator and others who have discussed our articles with us for their thoughtful questions and critiques

“I See You Have Been Convicted Of A Felony; Can You Tell Me About That?” Workforce Development Challenges For Restorative Citizens Seeking Employment, Terrance Hinton

All Faculty and Staff Scholarship

Incarceration has been an issue nationwide in the United States for decades due to policies from the 1970s, 1980s, and 1990s that lead to mass increases in incarceration. In the past decade, several states have overhauled their criminal sentencing and prison structure to lower prison populations. This has resulted in the release of thousands of restorative citizens and has expanded the need for reentry services. Released individuals who have been incarcerated face a number of social, political, and economic barriers that prevent them from re-entering society successfully. The inability to obtain employment is often cited as one of the most …

Feminist Action Against Pornography In Japan: Unexpected Success In An Unlikely Place, Caroline Norma, Seiya Morita

Dignity: A Journal of Analysis of Exploitation and Violence

In late 2016 a feminist movement against problems of commercial sexual exploitation, and especially issues of coerced pornography filming, arose in Japan. This article describes the history of this movement as it mobilized to combat human rights violations perpetrated by the country’s pornographers. The movement’s success came not spontaneously or haphazardly; in fact, it was orchestrated earlier over a full decade-and-a-half by activists who persevered in researching and highlighting pornography’s harms in a civil environment of hostility, isolation and social derision, even among progressive groups and individuals. The Anti-Pornography and Prostitution Research Group (APP) was particularly prominent in this history. …

The Morning Meeting: Fostering A Participatory Democracy Begins With Youth In Public Education, Rebecca C. Tilhou

Teaching & Learning Faculty Publications

There is a faltering sense of democracy in America's current political climate due to polarized opinions about leadership's decisions and antagonistic political parties. John Dewey (1916) proposed that education is the place to foster democracy, as schools can provide a platform to actively engage students in authentic democratic experiences that will empower them to act democratically beyond the walls of the school. The democratic schools that emerged during the Free School Movement of the 1960s and 1970s embody Dewey's philosophy, specifically with the shared governance occurring in their School Meetings. Unfortunately, American public education's present preoccupation with standardization, proficiency scores, …

Teaching & Learning Faculty Publications

The COVID-19 induced school shutdown dramatically decreased students’ hands-on STEM learning opportunities. An NSF-funded program partnering preservice teachers and undergraduate engineering students to teach robotics to fifth graders was adapted to a virtual format via Zoom. A case study intimately explored one team’s experience as they engineered bio-inspired robots over five weekly sessions. Zoom recordings, written reflections, and lesson slides were analyzed to describe how the virtual context shaped the lesson and influenced the preservice teacher’s experience. All three participants successfully engineered a robotic flower indicating hands-on robotics instruction is feasible in an online format. The virtual context increased the …

High Tech, High Risk: Tech Ethics Lessons For The Covid-19 Pandemic Response, Emanuel Moss, Jacob Metcalf

Publications and Research

The COVID-19 pandemic has, in a matter of a few short months, drastically reshaped society around the world. Because of the growing perception of machine learning as a technology capable of addressing large problems at scale, machine learning applications have been seen as desirable interventions in mitigating the risks of the pandemic disease. However, machine learning, like many tools of technocratic governance, is deeply implicated in the social production and distribution of risk and the role of machine learning in the production of risk must be considered as engineers and other technologists develop tools for the current crisis. This paper …

Role Of Art In International Relations : Analysis Of The Key Operational Patterns On The Example Of French Cultural Cluster, Maria Meshcherskaya

MA Theses

Reflecting on the role of art in the socio-cultural context would be unfair not to notice its unconventional nature of the transformation, definition, and understanding, depending on the time, place, and society, which would start the dispute. Yet, there is still no one answer or guide on how does art work as a singular system, using multiple mediums for translating, spreading, and sharing values from one culture to the another, without destroying origins of the message, but organically adopting it for the new environment. Luckily there is a set of tendencies kept by centuries, analysis of which might bring a …

A Five-Sample Confirmatory Factor Analytic Study Of Burnout-Depression Overlap, Renzo Bianchi, Irvin Sam Schonfeld, Jay Verkuilen

Publications and Research

Objective: It has been asserted that burnout—a condition ascribed to unresolvable job stress—should not be mistaken for a depressive syndrome. In this confirmatory factor analytic study, the validity of this assertion was examined.

Methods: Five samples of employed individuals, recruited in Switzerland and France, were mobilized for this study (N = 3,113). Burnout symptoms were assessed with the Shirom–Melamed Burnout Measure, the Maslach Burnout Inventory (MBI)—General Survey, and the MBI for Educators. Depressive symptoms were measured with the PHQ‐9.

Results: In all five samples, the latent factors pertaining to burnout’s components correlated on average more highly with the latent Depression …

Integrating Social Emotional Skill Development Throughout College Access Program Activities: A Profile Of The Princeton University Preparatory Program, Catherine M. Millett, Marisol J. C. Kevelson

Journal of College Access

In a prior study we demonstrated that college access program participants have positive views of the extent to which the program supports the development of their social and emotional skills and related college help-seeking behaviors in college. In this follow-up study, we explore the extent to which participant views vary by length of participation in the program in high school (i.e., dosage) and the extent to which alumni enrolled in college differ from college graduate alumni in their perceptions of the influences of the college access program. Results reveal that a multi-year college access program may influence different social and …

Achieving An Equitable Transition To Open Access For Researchers In Lower And Middle-Income Countries, Andrea Powell, Rob Johnson, Rachel Herbert

Copyright, Fair Use, Scholarly Communication, etc.

Introduction

The origins of this White Paper can be traced to a discussion started in mid-2019 between a number of scholarly publishers and the Publisher Coordinator for Research4Life (a role that is supported financially by the STM Association). These interlocutors voiced concern that while the publishing and research communities in the developed world were making steady and positive progress towards universal Open Access based on a ‘pay to publish’ model, those same communities in the less developed lower and middle-income countries (often referred to as the “Global South”) were being excluded from these discussions. Following discussions at the STM Board …
