Gamifying An Assessment Method: What Signals Are Organizations Sending To Applicants?, Konstantina Georgiou, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Purpose: The paper aims to expand the authors' knowledge on gamification and the signals sent on behalf of the organization when gamified assessments are used. The authors examine the mechanisms through which the use of gamification into an assessment method may increase the attractiveness of an organization as a prospective employer. Design/methodology/approach: The first study examines, following a longitudinal design, the signals that an organization sends to applicants about the organization's symbolic traits (e.g. innovativeness), through the characteristics of a gamified assessment, in terms of enjoyment and flow and impact on organizational attractiveness. Upon clarifying this mechanism, the second study …

Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang

Research Collection Lee Kong Chian School Of Business

Capital expenditures of U.S. public firms, relative to total assets, decrease by more than half from 1980 to 2020. The decline is pervasive across industries and firms of different characteristics and cannot be explained by the usual determinants of investment and many other seemingly plausible reasons. The decline is consistent with the transformation in production technology — firms rely more on intangible capital and less on fixed assets in production. Industry-level analyses yield supporting evidence. We observe similar declining trend in capital expenditure in other developed countries but not in most emerging markets.

Understanding The Impact Of Emotional Support On Mental Health Resilience Of The Community In The Social Media In Covid-19 Pandemic, Xuan Hu, Yanqing Song, Ruilin Zhu, Shuang He, Bowen Zhou, Xuelian Li, Han Bao, Shan Shen, Bingsheng Liu

Research Collection Lee Kong Chian School Of Business

Background: Emotional support in social media can act as a buffer against the negative impact of affective disorders. However, empirical evidence relating to emotional support in social media and how it influences the wider public remains scanty. The objective of this study is therefore to conduct a prototype investigation into the translation mechanism of emotional support in social media, providing empirical evidence for practitioners to use to tackle mental health issues for the wider public. Methods: A regression model is proposed to examine the relationship between perceived and received emotional support. Received emotional support is set as the dependent variable …

Order Constraints In Optimal Transport, Fabian Lim, Laura Wynter, Shiau Hong Lim

Research Collection School Of Computing and Information Systems

Optimal transport is a framework for comparing measures whereby a cost is incurred for transporting one measure to another. Recent works have aimed to improve optimal transport plans through the introduction of various forms of structure. We introduce novel order constraints into the optimal transport formulation to allow for the incorporation of structure. We define an efficient method for obtaining explainable solutions to the new formulation that scales far better than standard approaches. The theoretical properties of the method are provided. We demonstrate experimentally that order constraints improve explainability using the e-SNLI (Stanford Natural Language Inference) dataset that includes human-annotated …

Time Dependent Orienteering Problem With Time Windows And Service Time Dependent Profits, M. Khodadadian, A. Divsalar, C. Verbeeck, Aldy Gunawan, P. Vansteenwegen

Research Collection School Of Computing and Information Systems

This paper addresses the time dependent orienteering problem with time windows and service time dependent profits (TDOPTW-STP). In the TDOPTW-STP, each vertex is assigned a minimum and a maximum service time and the profit collected at each vertex increases linearly with the service time. The goal is to maximize the total collected profit by determining a subset of vertices to be visited and assigning appropriate service time to each vertex, considering a given time budget and time windows. Moreover, travel times are dependent of the departure times. To solve this problem, a mixed integer linear model is formulated and a …

Engaging Individuals In Disease Prevention Behaviours During A Pandemic, Su Lin Yeo, Smu Office Of Research

Research@SMU Infographics

While research has shown that individuals’ belief in a dangerous world can lead to disease prevention behaviours, the combined effects of this belief and the perception of the effectiveness of government’s messages in adopting disease prevention behaviours were not known previously. The COVID-19 pandemic has provided SMU Associate Professor Yeo Su Lin and her collaborators the opportunity to study the influence of the two constructs and the effectiveness in driving disease prevention behaviours.

Asean-Korea Strategic Partnership In New Asian Regionalism, Rachel Liting Chang

Centre for Commercial Law in Asia

Over the past two decades, Asia has witnessed increasing regional trade integration with the rapid increase of free trade agreements (FTAs), constituting almost half of global trade pacts. Such a phenomenon has been said to give rise to “new Asian regionalism”, which is defined as a fundamental change in the multilateral trading system. It is a novel and normative integration process which focuses on ASEAN, and in particular the ASEAN Plus Six framework underlying Asia’s increasing economic power.

Spatial Panel Data Models: Unbalanced Panel, Threshold Effect And Network Structure, Xiaoyu Meng

Dissertations and Theses Collection (Open Access)

This thesis studies the estimation and inference problems for spatial panel data models when the panels are unbalanced, when the panels contain threshold effects, or when the panels contain time-varying network structures. These three scenarios divide the thesis naturally into three chapters.

The first chapter considers estimation and inferences for fixed effects spatial panel data models based on unbalanced panels that result from randomly missing spatial units. The unbalanced nature of the panel data renders the standard method of estimation inapplicable. In this chapter, we proposed an M-estimation method where the estimating functions are obtained by adjusting the concentrated quasi …

Under What Circumstances Are Chinese Entrepreneurs Reluctant To Go Public, Ting Huang

Dissertations and Theses Collection (Open Access)

As secondary stock markets often overestimate corporate value, many Chinese entrepreneurs seek to achieve their wealth targets by going public. However, some companies in China do not want to go public. This paper utilises multi-case research methods to develop theories about which factors lead to corporate reluctance to go public. Case studies show that compared with entrepreneurs with lower shareholdings, entrepreneurs with higher shareholdings have stronger long-term orientations and a greater desire for control and are more reluctant to go public. Industry characteristics affect entrepreneurs’ long-term orientation, desire for control, and early listing experience, thus influencing their listing decision-making. Empirical …

Gauging The Acceptance Of Contact Tracing Technology: An Empirical Study Of Singapore Residents’ Concerns With Sharing Their Information And Willingness To Trust, Ee-Ing Ong, Wee Ling Loo

Research Collection Yong Pung How School Of Law

In response to the COVID-19 pandemic, governments began implementing various forms of contact tracing technology. Singapore’s implementation of its contact tracing technology, TraceTogether, however, was met with significant concern by its population, with regard to privacy and data security. This concern did not fit with the general perception that Singaporeans have a high level of trust in its government. We explore this disconnect, using responses to our survey (conducted pre-COVID-19) in which we asked participants about their level of concern with the government and business collecting certain categories of personal data. The results show that respondents had less concern with …

A Cross-Country Investigation Of Social Image Motivation And Acceptance Of Lab-Grown Meat In Singapore And The United States, Mark Chong, Angela K. Y. Leung, Verity Lua

Research Collection Lee Kong Chian School Of Business

This research has three goals. First, it sets out to compare consumer acceptance of lab-grown meat in the U.S. and in Singapore. Second, it seeks to explain the difference in Americans' and Singaporeans' acceptance of lab-grown meat by examining their eating motivations. Specifically, we focused on social image motivations – the motivations to present oneself positively in social contexts. Third, this study also aims to assess if exposure to information about lab-grown meat communicated by celebrity versus expert social media influencers (SMIs) can impact people's acceptance of lab-grown meat products. Our analysis showed that Singaporean participants had greater acceptance of …

Essays On Social Choice And Implementation Theory, Paulo Daniel Salles Ramos

Dissertations and Theses Collection (Open Access)

We present here three essays. The first two are about Social Choice Theory and explore under what domain restrictions is possible to obtain a Social Choice Function that is Well Behaved as well as Monotonic, and what other characteristics can be inferred about such functions on that domain. The last essay is about Implementation Theory and explore how to obtain a more compelling form of implementation than pure Nash Equilibrium for finite environments using finite mechanisms.

Three Essays On Development Economics And Human Capital, Arpita Khanna

Dissertations and Theses Collection (Open Access)

In the first chapter, we estimate the impact of exposure to the 2015 Nepal Earthquake on intimate partner violence with two rounds of Demographic and Health Surveys data. Using differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in intimate partner violence in the urban areas but not in the rural areas. This is possibly due to an increase in the stress felt by the victims. We also offer some evidence that the impact heterogeneity between the urban and rural areas is attributable to the differences in the reconstruction processes and assistance …

Bayesian And Machine Learning Methods With Applications In Asset Pricing, Yaohan Chen

Dissertations and Theses Collection (Open Access)

The dissertation consists of three essays on asset pricing by constructing new data set and developing new methodologies. In the first chapter, we conduct empirical studies on the volatility-managed portfolios in the Chinese stock market. Using data from the Chinese stock market, we have found that the main empirical findings in Moreira and Muir (2017) break down. Based on the empirical findings, we exploit a comprehensive set of $99$ equity strategies in the Chinese stock market to analyze the value of managed portfolios. Based on these $99$ equity trading strategies, we find that there exists no systematic gain from scaling …

Essays On Long Memory Time Series And Panel Models, Shuyao Ke

Dissertations and Theses Collection (Open Access)

This dissertation studies different long memory models. The first chapter considers a time series regression model where both the regressors and error term are locally stationary long memory processes with time-varying memory parameters, and the regression coefficients are also allowed to be time-varying. We consider a frequency-domain least squares estimator with kernelized discrete Fourier transform and derive its pointwise asymptotic normality and uniform consistency. A specification test on the constancy of coefficients is provided. The second chapter studies a linear regression panel data model with interactive fixed effects where the regressors, factors and idiosyncratic error terms are all stationary but …

Effects Of Positive Reappraisal And Self-Distancing On Meaning-Making In Negative Experiences, Yong Hao Clement Lau

Dissertations and Theses Collection (Open Access)

Scant research has investigated the impact of common daily adversities on one’s sense of meaning, and how one can cope and find meaning in these distressing events. Drawing on the meaning-making model and tripartite model of meaning, this study sought to examine how using a combination of coping strategies (i.e., positive reappraisal and self-distancing) can help individuals to derive greater situational meaning (i.e., meaning from the experience), greater global meaning (i.e., meaning in life)—across three facets (i.e., coherence, significance, and purpose). Specifically, it is proposed that the effects of positive reappraisal on promoting meaning would be enhanced by adopting a …

Information Sources, Perceived Personal Experience, And Climate Change Beliefs, Sonny Rosenthal

Research Collection College of Integrative Studies

This study proposes and tests a model of serial mediation based on the norm activation model and value-belief-norm theory. It argues that beliefs about climate change are related to perceived personal experience, which is related to the use of different information sources. Structural equation modeling of survey data from 1084 adult residents of Singapore found mixed support for three hypotheses. Results showed that perceived personal experience of climate change was related to the use of traditional media (β = 0.20), social media (β = 0.16), and interpersonal sources (β = 0.13), but not institutional sources. Perceived personal experience of climate …

The Anti-Money Laundering Framework For Precious Stones And Metals Dealers In Singapore, Vincent Ooi

Research Collection Yong Pung How School Of Law

Precious stones and metals have commonly been used throughout the world as a conduit for terrorism and money laundering activities. Such illicit use of these assets has called for its much-needed attention from a regulatory perspective. This is particularly relevant in a financial haven such as Singapore. Accordingly, this article seeks to explore how several of the most common trading and investment activities involving precious stones and metals in Singapore are regulated.

Linking Creativity To Psychological Well-Being: Theoretical Insights From Instrumental Emotion Regulation, Angela K. Y. Leung, Brandon Koh, Riyang Phang, Sean T. H. Lee, Tengjiao Huang

Research Collection School of Social Sciences

Research has recognized that people regulate their emotions not only for seeking pleasurable experiences but also for receiving instrumental gains. We draw on the theoretical framework of instrumental emotion regulation (IER; Tamir, 2005, 2009) to shed new light on the relationships among creativity, emotion, and psychological well-being. We outline propositions that explain why there are concurrent creative and well-being benefits when people experience emotional states that are consistent with their personality trait (e.g., worrisome emotions being consistent with trait neuroticism) even if such trait-consistent emotions are negative. The IER perspective offers new interpretations of the creativity—well-being relationship through motivating a …

Helping-Seeking Tendencies And Subjective Well-Being: A Cross-Cultural Comparison Of The United States And Japan, Verity Yu Qing Lua, Nadyannam N. Majeed, Andree Hartanto, Angela K. Y. Leung

Research Collection School of Social Sciences

Help-seeking is commonly conceived as an instrumental behavior that improves people’s subjective well-being. However, most findings supporting a positive association between help-seeking and subjective well-being are observed in independence-preferring countries. Drawing from research demonstrating that the pathways to subjective well-being are culturally divergent, we posit that help-seeking tendencies may be detrimental to subjective well-being for members in interdependence-preferring countries where norms for preserving relational harmony and face concerns are prevalent. This study tested the moderating role of country in the relationship between help-seeking tendencies and subjective well-being using data from 5,068 American and Japanese participants. Results revealed that although help-seeking …

Start-Up Firms And Corporate Culture: Evidence From Advertised Corporate Culture, Jungho Lee

Research Collection School Of Economics

I document advertised corporate culture among start-up firms from an online job board. Two corporate-culture types emerge, one that concerns the well-being of em- ployees (worker-centered culture) and another that emphasizes other values, such as cus- tomers, firms, and markets (firm-centered culture). The worker-centered culture attracts 20% more applications than the other culture type. Firms advertising the worker-centered culture exploit worker preference by paying 5% lower salaries than measurably similar jobs. Using a standard model of business creation, I show financially constrained start- ups are incentivized to advocate popular culture, even though doing so is not optimal without financial constraints.

A Consistent Specification Test For Dynamic Quantile Models, Peter Horvath, Jia Li, Zhipeng Liao, Andrew J. Patton

Research Collection School Of Economics

Correct specification of a conditional quantile model implies that a particular conditional moment is equal to zero. We nonparametrically estimate the conditional moment function via series regression and test whether it is identically zero using uniform functional inference. Our approach is theoretically justified via a strong Gaussian approximation for statistics of growing dimensions in a general time series setting. We propose a novel bootstrap method in this nonstandard context and show that it significantly outperforms the benchmark asymptotic approximation in finite samples, especially for tail quantiles such as Value-at-Risk (VaR). We use the proposed new test to study the VaR …

Weak Identification Of Long Memory With Implications For Inference, Jia Li, Peter C. B. Phillips, Shuping Shi, Jun Yu

Research Collection School Of Economics

This paper explores weak identification issues arising in commonly used models of economic and financial time series. Two highly popular configurations are shown to be asymptotically observationally equivalent: one with long memory and weak autoregressive dynamics, the other with antipersistent shocks and a near-unit autoregressive root. We develop a data-driven semiparametric and identification-robust approach to inference that reveals such ambiguities and documents the prevalence of weak identification in many realized volatility and trading volume series. The identification-robust empirical evidence generally favors long memory dynamics in volatility and volume, a conclusion that is corroborated using social-media news flow data.

Win: How Public Entrepreneurship Can Transform The Developing World, Tomoki Fujii

Research Collection School Of Economics

This book provides a story about the Infrastructure Development Company Limited (IDCOL) written from the perspective of its first full-time Chief Executive Officer. For those who have never heard of IDCOL, it was created in 1997 by the Government of Bangladesh as a nonbank financial institution to fill the financial gap for developing medium- to large-scale infrastructure. IDCOL had a very modest start with a nominal paid-up capital of less than US$2,000, but its capital, equity, and reserves increased to US$110 million by 2020. During this massive expansion, IDCOL met various challenges. This book gives an account of these challenges …

Comparative Lessons In Sectional Title Laws: Mitigating Urban Inequality In South Africa, Edward S. W. Ti

Research Collection Yong Pung How School Of Law

Urban inequality in South Africa is a formidable problem that is linked to the injustices of its historical apartheid past. This paper identifies sectional titles, a form of property ownership where proprietors wholly own their apartment unit while co-owning the land and common property, as critical to providing more affordable housing. Sectional title schemes mitigate urban inequality by giving a greater proportion of the country the opportunity to own legally secure, well-located dwellings while serving as a platform where communal living could take place. Two suggestions how sectional title legislation can further alleviate aspects of urban inequality are made (1) …
