Impact Of Restrictive Red Blood Cell Transfusion Strategy On Thrombosis-Related Events: A Meta-Analysis And Systematic Review, Mairehaba Maimaitiming, Chenxiao Zhang, Jingui Xie, Zhichao Zheng, Haidong Luo, Oon Cheong Ooi Mar 2022

Impact Of Restrictive Red Blood Cell Transfusion Strategy On Thrombosis-Related Events: A Meta-Analysis And Systematic Review, Mairehaba Maimaitiming, Chenxiao Zhang, Jingui Xie, Zhichao Zheng, Haidong Luo, Oon Cheong Ooi

Research Collection Lee Kong Chian School Of Business

Background and Objectives There is an ongoing controversy regarding the risks of restrictive and liberal red blood cell (RBC) transfusion strategies. This meta-analysis assessed whether transfusion at a lower threshold was superior to transfusion at a higher threshold, with regard to thrombosis-related events, that is, whether these outcomes can benefit from a restrictive transfusion strategy is debated. Materials and Methods We searched PubMed, Cochrane Central Register of Controlled Trials and Scopus from inception up to 31 July 2021. We included randomized controlled trials (RCTs) in any clinical setting that evaluated the effects of restrictive versus liberal RBC transfusion in adults. …


Forced Moves And Home Maintenance: The Amplifying Effects Of Mortgage Payment Burden On Underwater Homeowners, John Harding, Li Jing, Stuart Rosenthal, Xirui Zhang Mar 2022

Forced Moves And Home Maintenance: The Amplifying Effects Of Mortgage Payment Burden On Underwater Homeowners, John Harding, Li Jing, Stuart Rosenthal, Xirui Zhang

Research Collection School Of Economics

Although the adverse effect of high loan to value ratios (LTV) on mortgage default is known, the potential amplifying effect of high payment-to-income (PTI) ratios that can force families out of their homes has received limited attention. High PTI and LTV can also add to default costs by discouraging home maintenance. Using the 1985-2013 AHS panel, we show that high PTI prompts families to move and especially so for households with LTV above 120%. This lends support for policies like HAMP and HARP that seek to reduce forced moves and mortgage default by lowering mortgage payment burden for financially stressed …


The Economy Of Time, The Rationalisation Of Resources: Discipline, Desire And Deferred Value In The Playing Of Gacha Games, Orlando Woods Mar 2022

The Economy Of Time, The Rationalisation Of Resources: Discipline, Desire And Deferred Value In The Playing Of Gacha Games, Orlando Woods

Research Collection School of Social Sciences

This paper offers a counterpoint to existing research that explores the associations between gacha games and gambling. Whilst existing research tends to advance a view that playing these games is equivalent to gambling, I contend that such assertions rest on analyses that focus almost exclusively on investing money in the game. Moreover, they tend to view the game as separate from the structuring forces of everyday life. Arguing that players are embedded within a double structural frame that moderates the extent of seemingly ‘irrational’ playing behaviours, I reinterpret grinding as a form of temporal investment that is motivated by more …


The Resilience Of Diversified Clusters: Reconfiguring Commodity Networks In Rural China During The Covid-19 Pandemic, Zhanping Hu, Qian Forrest Zhang Mar 2022

The Resilience Of Diversified Clusters: Reconfiguring Commodity Networks In Rural China During The Covid-19 Pandemic, Zhanping Hu, Qian Forrest Zhang

Research Collection School of Social Sciences

We conceptualize typical rural communities in China as diversified economic clusters. In normal times, economic actors in these communities rarely cooperate with each other, but are integrated into separate commodity chains. These “diversified clusters”, however, show resilience and flexibility when an external shock—the COVID-19 pandemic—disrupts the spatial connections throughout the existing commodity chains. In this study, we use primary field data collected from one typical rural community in Northern China to show how economic diversity, aided by social networks and space-shrinking technologies, allowed for the vertical commodity chains to be reconfigured temporarily into localized horizontal commodity networks to cope with …


Coordinated Delivery To Shopping Malls With Limited Docking Capacity, Ruidian Song, Hoong Chuin Lau, Xue Luo, Lei Zhao Mar 2022

Coordinated Delivery To Shopping Malls With Limited Docking Capacity, Ruidian Song, Hoong Chuin Lau, Xue Luo, Lei Zhao

Research Collection School Of Computing and Information Systems

Shopping malls are densely located in major cities such as Singapore and Hong Kong. Tenants in these shopping malls generate a large number of freight orders to their contracted logistics service providers, who independently plan their own delivery schedules. These uncoordinated deliveries and limited docking capacity jointly cause congestion at the shopping malls. A delivery coordination platform centrally plans the vehicle routes for the logistics service providers and simultaneously schedules the dock time slots at the shopping malls for the delivery orders. Vehicle routing and dock scheduling decisions need to be made jointly against the backdrop of travel time and …


The Effects Of Conflict Type And Conflict Expression Intensity On Conflict Management, Gergana Todorova, Kenneth T. Goh, Laurie Weingart Mar 2022

The Effects Of Conflict Type And Conflict Expression Intensity On Conflict Management, Gergana Todorova, Kenneth T. Goh, Laurie Weingart

Research Collection Lee Kong Chian School Of Business

Purpose: This paper aims to add to the current knowledge about conflict management by examining the relationships between conflict type, conflict expression intensity and the use of the conflict management approach. Design/methodology/approach: The authors test theory-based hypotheses using a field study of new product development teams in an interdisciplinary Masters program (Study 1) and an experimental vignette study (Study 2). Findings: Results show that people are more likely to respond to task conflict and conflicts expressed with less intensity using collectivistic conflict management approaches (i.e. problem-solving, compromising and yielding), and to relationship conflicts and conflicts expressed with higher intensity through …


It's So Boring - Or Is It? Examining The Role Of Mindfulness For Work Performance And Attitudes In Monotonous Jobs, Andreas Wihler, Ute R. Hulsheger, Jochen Reb, Jochen I. Menges Mar 2022

It's So Boring - Or Is It? Examining The Role Of Mindfulness For Work Performance And Attitudes In Monotonous Jobs, Andreas Wihler, Ute R. Hulsheger, Jochen Reb, Jochen I. Menges

Research Collection Lee Kong Chian School Of Business

We examine the role of employee mindfulness in the context of highly monotonous work conditions. Integrating research on task monotony with theorizing on mindfulness, we hypothesized that mindfulness is negatively associated with the extent to which employees feel generally bored by their jobs. We further hypothesized that this lower employee boredom would relate to downstream outcomes in the form of job attitudes (job satisfaction and turnover intentions) and task performance. We examined both objective task performance quality and quantity to shed light on the complexity of the mindfulness-task performance relation, which has so far mostly been investigated using subjective supervisor …


Human-Algorithm Collaboration Works Best If Humans Lead (Because It Is Fair!), David De Cremer, Jack Mcguire Mar 2022

Human-Algorithm Collaboration Works Best If Humans Lead (Because It Is Fair!), David De Cremer, Jack Mcguire

Research Collection Lee Kong Chian School Of Business

Autonomous algorithms are increasingly being used by organizations to reach ever increasing heights of organizational efficiency. The emerging business model of today therefore appears to be one where autonomous algorithms are gradually expanding their occupation into becoming a leading decision-maker, and humans by default become increasingly more subordinate to such decisions. We address the question of whether this business perspective is consistent with the sort of collaboration employees want to have with algorithms at work. We explored this question by investigating in what way humans preferred to collaborate with algorithms when making decisions. Using two experimental studies (Study 1, n …


Insider Sales Under The Threat Of Short Sellers: New Hypothesis And New Tests, Kemin Wang, Rencheng Wang, K. C. John Wei, Bohui Zhang, Yi Zhou Mar 2022

Insider Sales Under The Threat Of Short Sellers: New Hypothesis And New Tests, Kemin Wang, Rencheng Wang, K. C. John Wei, Bohui Zhang, Yi Zhou

Research Collection School Of Accountancy

Using the Regulation SHO program as a quasi-experiment, we document that the threat of short selling has a negative effect on the volume of opportunistic insider selling and a positive effect on its profitability for each transaction. These effects are stronger among firms with higher litigation risk, greater media coverage, and executives who have more of their firms' stock-related holdings. We further find robust evidence when we extend the analyses to short selling deregulations in the Chinese and Hong Kong stock exchanges. Overall, our findings suggest that short sellers play a disciplinary role in opportunistic insider selling.


Does The Dna Of Business Schools Need To Change?, Arnoud Cyriel Leo De Meyer Mar 2022

Does The Dna Of Business Schools Need To Change?, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

The causes, effects and consequences concern corporate governance and organisational management as much as political conflict, environmental sustainability and foreign diplomacy. In Business Schools on an Innovation Mission, a report released by the Association to Advance Collegiate Schools of Business in May 2010, management and leadership were clearly positioned, side-by-side with science and technology, as vital components to the innovation value chain. The business world exists as an eco-system of business, government, NGOs and non-profits, each interlocking. To be truly a "School for Business" it is also important to build strong relationships and strategic partnerships with the business world. In …

Expected Return, Volume, And Mispricing, Yufeng Han, Dashan Huang, Dayong Huang, Guofu Zhou Mar 2022

Expected Return, Volume, And Mispricing, Yufeng Han, Dashan Huang, Dayong Huang, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

We find that expected return is related to trading volume positively among underpriced stocks but negatively among overpriced stocks. As such, trading volume amplifies mispricing. Our results are robust to alternative mispricing and trading volume measures, alternative portfolio formation methods, and controlling for variables that are known to have amplification effects on mispricing. By attributing trading volume to investor disagreement, we show that our results are consistent with the recent theoretical model of Atmaz and Basak (2018) in that investor disagreement predicts stock returns conditional on expectation bias.


Scaled Pca: A New Approach To Dimension Reduction, Dashan Huang, Fuwei Jiang, Kunpeng Li, Guoshi Tong, Guofu Zhou Mar 2022

Scaled Pca: A New Approach To Dimension Reduction, Dashan Huang, Fuwei Jiang, Kunpeng Li, Guoshi Tong, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

This paper proposes a novel supervised learning technique for forecasting: scaled principal component analysis (sPCA). The sPCA improves the traditional principal component analysis (PCA) by scaling each predictor with its predictive slope on the target to be forecasted. Unlike the PCA that maximizes the common variation of the predictors, the sPCA assigns more weight to those predictors with stronger forecasting power. In a general factor framework, we show that, under some appropriate conditions on data, the sPCA forecast beats the PCA forecast, and when these conditions break down, extensive simulations indicate that the sPCA still has a large chance to …


Mapping Consumer's Cross-Device Usage For Online Search: Mobile- Vs. Pc-Based Search In The Purchase Decision Process, Sangman Han, Jin K. Han, Il Im, Sung In Jung, Jung Won Lee Mar 2022

Mapping Consumer's Cross-Device Usage For Online Search: Mobile- Vs. Pc-Based Search In The Purchase Decision Process, Sangman Han, Jin K. Han, Il Im, Sung In Jung, Jung Won Lee

Research Collection Lee Kong Chian School Of Business

The ubiquity of both mobile devices and PC’s has enabled the modern-day consumer to engage in cross-platform online searches as a new norm. The accumulated knowledge on cross-device search behavior to date, however, emanates largely from industry reports and at an aggregate level. To better understand the individual consumer’s purchase decision process, we set out to investigate contingencies of what (subject of search), how (device of choice), and when (stage in the buying decision). To this end, we utilize a panel data consisting of clickstream from mobile and PC searches, coupled with entropy-based metric to chart the breadth and depth …


On The Test Accuracy And Effective Control Of The Covid-19 Pandemic: A Case Study In Singapore, Guang Cheng, Sarah Yini Gao, Yancheng Yuan, Chenxiao Zhang, Zhichao Zheng Mar 2022

On The Test Accuracy And Effective Control Of The Covid-19 Pandemic: A Case Study In Singapore, Guang Cheng, Sarah Yini Gao, Yancheng Yuan, Chenxiao Zhang, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

This study examines the impact of coronavirus disease 2019 (COVID-19) test accuracy (i.e., sensitivity and specificity) on the progression of the pandemic under two scenarios of limited and unlimited test capacity. We extend the classic susceptible–exposed–infectious–recovered model to incorporate test accuracy and compare the progression of the pandemic under various sensitivities and specificities. We find that high-sensitivity tests effectively reduce the total number of infections only with sufficient testing capacity. Nevertheless, with limited test capacity and a relatively high cross-infection rate, the total number of infected cases may increase when sensitivity is above a certain threshold. Despite the potential for …

Financial Intermediaries And Contagion In Market Efficiency: The Case Of Etfs, Claire Yurong Hong, Frank Weikai Li, Avanidhar Subrahmanyam

Research Collection Lee Kong Chian School Of Business

Capital constraints of financial intermediaries can affect liquidity provision. We investigate whether these constraints spillover and consequently cause contagion in the degree of market efficiency across assets managed by a common intermediary. Specifically, we provide evidence of strong comovement in pricing gaps between ETFs and their constituents for ETFs served by the same lead market maker (LMM). The effects are stronger for ETFs that are more illiquid and volatile, when the underlying constituents of the ETFs are more costly to arbitrage, and for LMMs with more constrained capital. Using extreme disruptions in debt markets during COVID-19 as an experiment, we …


How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo Mar 2022

How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo

Research Collection Lee Kong Chian School Of Business

This paper presents new evidence on the economic role of private equity buyouts by exploiting the staggered adoption of the constructive fraud provision by U.S. state courts. The law unintentionally shifts the credit default risk borne by existing unsecured creditors of the buyout target to the selling shareholders and lenders in the form of ex-post litigation risk, thereby discouraging buyout activity. Using a difference-in-differences framework, I find that firms raise less capital, reduce payouts and investments, and form alliances with employees. Firms also avoid positive NPV projects that carry too much risk. These findings are consistent with managers enjoying a …


R&D Consortia In Competitive Supply Chains, Pascale Crama, Gaoyan Lu, Yi Xu Mar 2022

R&D Consortia In Competitive Supply Chains, Pascale Crama, Gaoyan Lu, Yi Xu

Research Collection Lee Kong Chian School Of Business

R&D consortia, which coordinate R&D activities of their member firms, have been successful in many industries. We study a model with two competing supply chains each consisting of a manufacturer and a supplier. The manufacturers compete in the final product market, and can conduct R&D to reduce unit product costs of their final products. The R&D can be done in three different ways: by the two manufacturers independently, by them jointly in a horizontal R&D consortium, or by the supplier and the manufacturer jointly in each supply chain in two vertical R&D consortia. We find that as compared to independent …

Customers want AR. But managers must have a proper understanding of how AR can help their brand before they invest in the technology. AR helps in entertaining and educating customers while also aiding them in evaluating products. AR can also promote online channel adoption while also encouraging category expansion. AR also benefits products that are less popular, less mainstream, and more expensive. But AR can also be expensive, time-consuming, and difficult to implement. Despite consumer demand, retailers must understand the costs and challenges associated with AR adoption before embarking on significant projects.

Research Collection Lee Kong Chian School Of Business

A key challenge in the resource allocation problem is to find near-optimal policies to serve different customers with random demands/revenues, using a fixed pool of capacity (properly configured). In this paper, we study the properties of three classes of allocation policies-responsive (with perfect hindsight), adaptive (with information updates), and anticipative (with forecast information) policies. These policies differ in how the information on actual demand and revenue of each customer is being revealed and integrated into the allocation decisions. We show that the analysis of these policies can be unified through the notion of "persistency" (or service level) values-the probability that …

This special issue includes several papers that focus on green and ethical finance. The climate change challenge has raised important questions about the financial sector's role in realizing a carbon-neutral global economy. The global financial crisis also brought critical ethical and governance questions for financial sector actors to the forefront. Such developments have together increased attention to environmental, social and governance (ESG) issues among financial sector practitioners, regulators, and investors. Recently, there has been an increasing focus of finance researchers on issues related to ESG and climate change, reflected also in the increasing number of submissions and published papers in …


Externalization In The Platform Economy: Social Platforms And Institutions, Liang Chen, Sali Li, Jiang Wei, Yang Yang Mar 2022

Externalization In The Platform Economy: Social Platforms And Institutions, Liang Chen, Sali Li, Jiang Wei, Yang Yang

Research Collection Lee Kong Chian School Of Business

The growing platform economy has revived the debate on the applicability of internalization theory in contemporary contexts. In moving this debate forward, we draw on insights from hybrids research and property rights theory to complement the internalization school. Our core contribution lies in a reconceptualization of platforms as a hybrid organizational form enabling the exchange of property rights between platform owners and complementors. Using social platforms as an example, we propose that improvement in a host country's intellectual property protection will increase the multinational platform's (MNP) level of internalization, and that the platform firm's governance capabilities may weaken the effect …

Digital payment has become one of the most popular payment methods all around the world, especially in countries that witnessed the rapid development of internet. As a traditional financial institution, commercial banks have been impacted by newly developed payment technology since third payment platforms have attracted customers to use the digital payment for daily consumption, transferring, and even investment. This paper focuses on analyzing whether and how the commercial banks in China have been affected by digital payment by using empirical methods. Systematic Generalized Method of Moments (SYS-GMM) is used to test the relationship between the productivity of commercial banks …


Estimating Financial Information Asymmetry In Real Estate Transactions In China: An Application Of Two-Tier Frontier Model, Ganlin Pu, Ying Zhang, Li-Chen Chou Mar 2022

Estimating Financial Information Asymmetry In Real Estate Transactions In China: An Application Of Two-Tier Frontier Model, Ganlin Pu, Ying Zhang, Li-Chen Chou

Research Collection School Of Computing and Information Systems

This study applies the two-tier stochastic frontier model to estimate the distribution of housing transaction information in Hangzhou, Wenzhou, Ningbo, and Jinhua (four cities in Zhejiang Province, China) during the year 2018, to analyze the difference in the price information acquired by the buyers and sellers in the transaction, and the effect of information asymmetry on the transaction price. The empirical results show that in each city, during the housing transaction process, the supplier has more complete information about house prices than consumers, and can therefore implement price discrimination strategies in setting service prices. Due to the disadvantage in acquired …
