Algorithms, Leadership, And Morality: Why A Mere Human Effect Drives The Preference For Human Over Algorithmic Leadership, Jack Mcguire, David De Cremer

Research Collection Lee Kong Chian School Of Business

Algorithms are increasingly making decisions in organizations that carry moral consequences and such decisions are considered to be ordinarily made by leaders. An important consideration to be made by organizations is therefore whether adopting algorithms in this domain will be accepted by employees and whether this practice will harm their reputation. Considering this emergent phenomenon, we set out to examine employees’ perceptions about (a) algorithmic decision-making systems employed to occupy leadership roles and make moral decisions in organizations, and (b) the reputation of organizations that employ such systems. Furthermore, we examine the extent to which the decision agent needs to …

Learning-Based Stock Trending Prediction By Incorporating Technical Indicators And Social Media Sentiment, Zhaoxia Wang, Zhenda Hu, Fang Li, Seng-Beng Ho, Erik Cambria

Research Collection School Of Computing and Information Systems

Stock trending prediction is a challenging task due to its dynamic and nonlinear characteristics. With the development of social platform and artificial intelligence (AI), incorporating timely news and social media information into stock trending models becomes possible. However, most of the existing works focus on classification or regression problems when predicting stock market trending without fully considering the effects of different influence factors in different phases. To address this gap, this research solves stock trending prediction problem utilizing both technical indicators and sentiments of the social media text as influence factors in different situations. A 3-phase hybrid model is proposed …

Dissertations and Theses Collection (Open Access)

With the increasing popularity of short video marketing in business world, understanding how to engage short video viewers has attracted the attention from both academics and practitioners. Prior studies on short videos mainly focus on how characteristics of users or the attributes of video content affect marketing effectiveness. As a heuristic cue of short video content, the video title is expected to grab viewers’ attention thereby playing an important role in influencing viewers’ attitudes towards the short video consumption. Drawing on signaling theory, I propose that the characteristics of short video titles, such as the length, the sentiment strength, and …

Dissertations and Theses Collection (Open Access)

The COVID-19 pandemic and complex global circumstances have prompted a heightened level of apprehension about food security in Singapore. With a land area of slightly over 700 square kilometers, of which a mere 1% is dedicated to agricultural purposes, Singapore's overall level of food self-sufficiency is less than 10%. Historically, Singapore has relied on imports to address its food deficits. However, due to the pandemic's impact and geopolitical tensions, which have resulted in instability within the global supply chain, Singapore is now compelled to re-evaluate its approach to food security. Consequently, there has been a substantial focus on exploring strategies …

Research Collection Lee Kong Chian School Of Business

Background: Interpersonal primary care continuity or chronic condition continuity (CCC) is associated with improved health outcomes. Ambulatory care-sensitive conditions (ACSC) are best managed in a primary care setting, and chronic ACSC (CACSC) require management over time. However, current measures do not measure continuity for specific conditions or the impact of continuity for chronic conditions on health outcomes. The purpose of this study was to design a novel measure of CCC for CACSC in primary care and determine its association with health care utilization. Methods: We conducted a cross-sectional analysis of continuously enrolled, nondual eligible adult Medicaid enrollees with a diagnosis …

Research On The Relationship Between Service-Oriented Manufacturing Platforms And Customer Enterprise Innovation — Evidence From The 3d Printing Industry, Donglai Zhao

Dissertations and Theses Collection (Open Access)

Micro, small and medium-sized enterprises (MSMEs) are highly flexible and creative and play a significant role in the national economy and in employment, innovation, and entrepreneurship. However, due to their relatively small size, low technical level, lack of funds and talent, and backward management, they generally face development predicaments, such as the pressure to survive and weak anti-risk abilities. Therefore, in addition to leveraging their initiative to develop their competitive strength, making full use of external public service resources has become one approach MSMEs can take to find a way out of such predicaments. Various service-oriented manufacturing platform enterprises have …

Attracting, deploying, motivating, developing and retaining talented employees is a corporate norm for meeting organisational goals. Proper human resource processes through rigorous mapping of employees according to the performance-potential matrix allow the grading of employees against peer groups to establish talent pools for development and internal succession planning.

Mindfulness originates from 2,500-year-old Buddhist spiritual practices and has a rare combination of spirituality and science. Eastern perspective originates from Asian traditions focusing on the self-regulation …

The Impact Of Subordinates’ Proactive Personality On Empowering Leadership, Xin Zhan

Dissertations and Theses Collection (Open Access)

Research has documented numerous benefits of proactive personality for employees’ job outcomes. However, the success of proactive employees largely depends on their leaders’ empowerment. Extant research has focused on the bright side of proactive personality for inducing empowerment, without considering its risks. We thus have an incomplete understanding of the effects of employees’ proactive personality on empowering leadership. I take a balanced perspective on proactive personality and propose that proactive personality has an inverted U-shaped relationship with empowering leadership, such that empowering leadership is highest when proactive personality is at a moderate level. I argue that leader-member exchange (LMX) mediates …

Regulating By New Technology: The Impacts Of The Sec Data Analytics On The Sec Investigations, Tian Deng

Dissertations and Theses Collection (Open Access)

Despite the Securities and Exchange Commission’s (SEC) growing emphasis on data analytics in recent years, there is scant research about whether the investment in data analytics accomplishes its objective of enhancing enforcement efficiency. This study examines the effects of the SEC regional offices’ use of data analytics on their investigation outcomes. The utilization of data analytics reduces information processing costs, thereby streamlining the enforcement process as a whole. I find that the SEC’s use of data analytics is associated with a 12% increase in the SEC’s investigation success rate. Such an improvement is greater for firms whose disclosure are more …

Informational Content Of Factor Structures In Simultaneous Discrete Response Models, Shakeeb Khan, Arnaud Maurel, Yichong Zhang

Research Collection School Of Economics

We study the informational content of factor structures in discrete triangular systems. Factor structures have been employed in a variety of settings in cross sectional and panel data models, and in this paper we attempt to formally quantify their informational content in a bivariate system often employed in the treatment effects literature. Our main findings are that under the factor structures often imposed in the literature, point identification of parameters of interest, such as both the treatment effect and the factor load, is attainable under weaker assumptions than usually required in these systems. For example, we show is that an …

Research Collection Yong Pung How School Of Law

This article explains in detail the legal issues surrounding the recent ABSD audit and how exactly the general anti-avoidance rule and the stamp duty avoidance surcharge in the Stamp Duties Act 1929 can be invoked by the IRAS.The article highlights the fact that it may not be enough for a property buyer to show that the '99-to-1' holding was intended to enable the buyer to qualify for a home loan and not 'for stamp duty avoidance'. The property buyer must be able to answer the additional question of why the transfer of the property is 'staggered' in two stages and …

Arousing Motives Or Eliciting Stories? On The Role Of Pictures In A Picture–Story Exercise, Philipp Schäpers, Stefan Krumm, Filip Lievens, Nikola Stenzel

Research Collection Lee Kong Chian School Of Business

Picture–story exercises (PSE) form a popular measurement approach that has been widely used for the assessment of implicit motives. However, current theorizing offers two diverging perspectives on the role of pictures in PSEs: either to elicit stories or to arouse motives. In the current study, we tested these perspectives in an experimental design. We administered a PSE either with or without pictures. Results from N = 281 participants revealed that the experimental manipulation had a medium to large effect for the affiliation and power motive domains, but no effect for the achievement motive domain. We conclude that the herein chosen …

The Effect Of Social Skills On Analyst Performance, Cong Cong Li, An-Ping Lin, Hai Lu

Research Collection School Of Accountancy

Social skills are important but difficult to measure. So far, few empirical studies have examined the effect of social skills on the performance of professionals. Using the number of LinkedIn connections as a proxy for social skills, we investigate the effect of financial analysts' social skills on their performance. We use multiple ways to validate the measure of social skills and show that analysts with better social skills produce more accurate earnings forecasts and that their stock recommendations elicit stronger market reactions. Furthermore, these socially skilled analysts are more likely to be voted as All-Star Analysts. This study provides the …

Covid Time: How Quarantine Affects Feelings Of Elapsed Time, Minju Han, Guy Voichek, Gal Zauberman

Research Collection Lee Kong Chian School Of Business

The lockdowns imposed in response to the COVID-19 pandemic abruptly upended people's lives and daily structure. In this survey of 1,506 Americans conducted in June 2020, we test how quarantine affects feelings of elapsed time (the subjective temporal distance from an event). We find that feelings of elapsed time are determined either by how people spent their time in quarantine or by how much time since an event was spent in quarantine, depending on whether people are still in quarantine at the time of evaluation. Specifically, whether people quarantined alone and the extent to which they maintained a temporal structure …

Knowledge, Skills, And Workforce Development: Commentary On Ackerman, Frederick L. Oswald, Karyssa A. Courey, Zihan Liu

Research Collection Lee Kong Chian School Of Business

Ackerman (2023) proposed incorporating a more comprehensive range of knowledge and skills into the conceptualization and operationalization of intelligence beyond traditional assessments. In agreeing with and extending this proposition, the current commentary focuses on the specific context of workforce development and highlights three critical considerations: (a) the development of knowledge and skills at different life stages of education and work, (b) the role of social contexts in knowledge and skill acquisition, and (c) quantitative and qualitative approaches to understanding and assessing a broader set of knowledge and skills in light of ongoing changes in the workplace. Overall, we encourage greater …

Multinational Family Firms’ Internationalization Depth And Breadth Following The Global Financial Crisis, Sebastian P. L. Fourné, Miriam Zschoche, Christian Schwens, Reddi Kotha

Research Collection Lee Kong Chian School Of Business

This study examines how large family firms react to a macroeconomic shock in terms of their internationalization depth and breadth. Building on new internalization theory and acknowledging the dysfunctional manifestations of bifurcation bias in large family-owned MNEs, we argue that an unexpected shock induces family firms to recombine their family firm-specific resources with their thus far underutilized or unequally treated nonfamily resources. This recombination allows most family firms to economize on bifurcation bias and leverage their resources as firm-specific advantages (FSAs) resulting in an increased depth and breadth of internationalization post shock (while some of them may continue to suffer …

Liquidity Constraints, Consumption, And Debt Repayment: Evidence From Macroprudential Policy In Turkey, Sumit Agarwal, Muris Hadzic, Changcheng Song, Yildirim Yildiray

Research Collection Lee Kong Chian School Of Business

Using account-level credit card data from a large Turkish bank, we study the impact of a unique credit card policy that increases minimum payment on consumption and debt repayment. We show that the policy reduces credit card spending and debt, boosts existing debt repayment, and reduces credit card delinquency. The credit card debt of affected consumers falls on average by 50% two years into the policy’s implementation. An increase in minimum payment has a stronger effect than does a decrease of a similar magnitude. We build a benchmark life cycle model with soft liquidity constraint to explain the reduction in …

Code Will Tell: Visual Identification Of Ponzi Schemes On Ethereum, Xiaolin Wen, Kim Siang Yeo, Yong Wang, Ling Cheng, Feida Zhu, Min Zhu

Research Collection School Of Computing and Information Systems

Ethereum has become a popular blockchain with smart contracts for investors nowadays. Due to the decentralization and anonymity of Ethereum, Ponzi schemes have been easily deployed and caused significant losses to investors. However, there are still no explainable and effective methods to help investors easily identify Ponzi schemes and validate whether a smart contract is actually a Ponzi scheme. To fill the research gap, we propose PonziLens, a novel visualization approach to help investors achieve early identification of Ponzi schemes by investigating the operation codes of smart contracts. Specifically, we conduct symbolic execution of opcode and extract the control flow …

Hedging Cryptos With Bitcoin Futures, Francis Liu, Natalie Packham, Meng-Jou Lu, Wolfgang Karl Haerdle

Sim Kee Boon Institute for Financial Economics

The introduction of derivatives on Bitcoin enables investors to hedge risk exposures in cryptocurrencies. Because of volatility swings and jumps in cryptocurrency prices, the traditional variance-based approach to obtain hedge ratios may not be suitable for hedgers. In this work, we consider two extensions of the traditional approach: first, different dependence structures are modelled by different copulae, such as the Gaussian, Student-t, Normal Inverse Gaussian and Archimedean copulae; second, different risk measures, such as value-at-risk, expected shortfall and spectral risk measures are employed to find the optimal hedge ratio. Extensive out-of-sample tests using the data from the time …
