Harnessing Digitalization For Sustainable Economic Development: Insights For Asia, John Beirne, David Fernandez
Harnessing Digitalization For Sustainable Economic Development: Insights For Asia, John Beirne, David Fernandez
Research Collection Lee Kong Chian School Of Business
Digitalization has helped to transform economies by enhancing competitiveness and productivity across a wide range of sectors. The use of big data and the rise of online platforms have accelerated this process over the past decade. In addition, the adoption of digital solutions in the face of social distancing and lockdown measures introduced due to the coronavirus disease 2019 (COVID-19) pandemic has been integral to the economic recovery process. The shift to a digitalized economy has also reduced barriers to market entry for firms, lowered inequality, and led to a promotion of social and economic inclusion. Advances in digital technology …

Research Collection Lee Kong Chian School Of Business
Acute kidney injury (AKI) is a frequent complication of cardiac surgery, which can lead to higher mortality and long-term renal function impairment. The effect of perioperative renin-angiotensin system inhibitors (RASi) therapy on AKI incidence in patients undergoing cardiac surgery remains controversial. We reviewed related studies in PubMed, Scopus, and Cochrane Library from inception to February 2020. Two randomized controlled trials and 21 cohort studies were included in the meta-analysis, involving 76,321 participants. The pooled odds ratio and 95% confidence interval were calculated using the DerSimonian and Laird random-effects model. The results showed no significant association between perioperative RASi therapy and …

Toward A Model Of Hardiness Development: The Effect Of Hope On Hardiness, Chin Heng Low, Paul Heng Leong Lim, Kevin Koh
Research Collection Lee Kong Chian School Of Business
Hardiness has been proven to help with the management of psychological stress. It is an important state-like personality dimension that individuals can develop to cope with stressors. However, there is currently insufficient understanding on why hardiness develops in people. Through an exploratory study based on 55 undergraduate university students who worked on an international consulting project in return for grades, this research examines the relationship between individuals’ hardiness components of commitment, control and challenge and hope components of willpower and waypower. It is found that individuals’ hope components may be positively related to specific hardiness components. This bears considerable theoretical …

Over the last year, Singapore firms have faced unforeseen market disruptions created by the Covid-19 pandemic. Worldwide country lockdowns, supply chain disruptions, and restrictions on business operations due to public health and safety measures posed non-trivial challenges. Many companies scampered to find alternative sources of revenue and ramp up their efforts at digitalisation - or risk the possibility of business closure.
Cross-Cryptocurrency Return Predictability, Li Guo, Bo Sang, Jun Tu, Yu Wang
Cross-Cryptocurrency Return Predictability, Li Guo, Bo Sang, Jun Tu, Yu Wang
Research Collection Lee Kong Chian School Of Business
Using the minute-frequency data on Binance, we find strong evidence of cross-cryptocurrency return predictability. The lagged returns of other cryptocurrencies serve as significant predictors of focal cryptocurrencies up to ten minutes, in line with slow information diffusion. The results are robust across various methods, including the adaptive LASSO and principal component analysis. Furthermore, a long-short portfolio formed on the past returns of cryptocurrencies can generate a daily return of 2.16% out-of-sample after accounting for transaction costs, indicating sizable economic value of cross-cryptocurrency return predictability.
Follow The Smoke: The Pollution Haven Effect On Global Sourcing, Heather Berry, Aseem Kaul, Narae Lee
Follow The Smoke: The Pollution Haven Effect On Global Sourcing, Heather Berry, Aseem Kaul, Narae Lee
Research Collection Lee Kong Chian School Of Business
Research abstract: We examine whether and how foreign environmental standards influence global sourcing decisions. Taking a question-driven approach, we find a negative association between the stringency of a country's environmental standards and its share in US imports for 82 manufacturing industries across 77 countries between 2006 and 2016. This pollution haven effect holds not only for sourcing from owned foreign operations (offshore integration), but also for sourcing from unrelated third parties abroad (offshore outsourcing), and is stronger in industries with high toxic emissions and low technological intensity. These results are robust across alternative measures of environmental stringency and to using …
The Curse Of The Original: How And When Heritage Branding Reduces Consumer Evaluations Of Enhanced Products, Minju Han, George E. Newman, Rosanna K. Smith, Ravi Dhar
The Curse Of The Original: How And When Heritage Branding Reduces Consumer Evaluations Of Enhanced Products, Minju Han, George E. Newman, Rosanna K. Smith, Ravi Dhar
Research Collection Lee Kong Chian School Of Business
Heritage branding is a common marketing strategy that has been shown to increase product appeal. Here, we find that certain forms of heritage branding can also have potentially negative consequences by leading consumers to react negatively to changes made to the brand’s original, flagship product—even if those changes objectively improve it. We demonstrate that when firms engage in heritage branding that emphasizes a brand’s longevity, consumers evaluate enhanced products less favorably than the original versions of those same products due to decreased perceptions of continuity authenticity. We demonstrate this effect across a variety of product domains (e.g., cosmetics, cookware, and …
Stock Return Prediction Using Financial News: A Unified Sequence Model Based On Hierarchical Attention And Long-Short Term Memory Networks, Haoling Chen, Peng Liu
Stock Return Prediction Using Financial News: A Unified Sequence Model Based On Hierarchical Attention And Long-Short Term Memory Networks, Haoling Chen, Peng Liu
Research Collection Lee Kong Chian School Of Business
Stock return prediction has been a hot topic in both research and industry given its potential for large financial gain. The return signal, apart from its inherent volatility and complexity, is often accompanied by a multitude of noises, such as other stocks’ performance, macroeconomic factors and financial news, etc. To better characterize these factors, we propose a new model that consists of two levels of sequence: an NLP-based module to capture the sequential nature of words and sentences in the financial news, and a time-series-based module to exploit the sequential nature of adjacent observations in the stock price. In this …

The world has witnessed an e-commerce boom in the past 2 decades, and Asia-Pacific is now driving the latest wave of growth. The Covid-19 pandemic has further accelerated consumers' growing preference for online consumption, with the Asia-Pacific region raking US$230 billion in online retail sales in 2020. This article is adapted from the authors' teaching case study - Alibaba Cainiao's Smart Green Logistics Strategy: Good for the Earth, Good for the Business.
Artificial Intelligence As Augmenting Automation: Implications For Employment, F. Ted Tschang, Esteve Almirall
Artificial Intelligence As Augmenting Automation: Implications For Employment, F. Ted Tschang, Esteve Almirall
Research Collection Lee Kong Chian School Of Business
There has been great concern in recent years that artificial intelligence (AI) may cause widespread unemployment, but proponents say that AI augments existing jobs. Both of these positions have substance, but there is a need is to articulate the mechanisms by which AI may actually do both, and in the process, transform work and business organizations alike. We use economic studies showing past transformations automation wrought on the structure of employment and skills (such as the favouring of nonroutine skills) to articulate a ground for discussion. We then use case evidence of AI and automation to show how AI is …

Smart Manufacturing And Its Implications For Singapore's Smes, Thomas Menkhoff, Surianarayanan Gopalakrishnan
Research Collection Lee Kong Chian School Of Business
While Covid-19 and the climate catastrophe continue to make headlines, local small and medium-sized enterprises (SMEs) are quietly setting the gears of Smart Manufacturing in motion with a strategic focus on digitising and automating production processes powered by "Industry 4.0" (I4.0) ready business models. A shared view among several interviewees we talked to recently in the context of an ongoing study on the impact of I4.0 on the business models of local manufacturers is that Industrial Internet-of-Things (IIoT), machine learning, visual computing, automation and digital twining are deemed of great importance for the long-term competitiveness of Singapore's manufacturing ecosystem on …
Volatility Timing Under Low-Volatility Strategy, Poh Ling Neo, Chyng Wen Tee
Volatility Timing Under Low-Volatility Strategy, Poh Ling Neo, Chyng Wen Tee
Research Collection Lee Kong Chian School Of Business
The authors show that the slope of the volatility decile portfolio’s return profile contains valuable information that can be used to time volatility under different market conditions in the United States. During good (bad) market conditions, the high- (low-) volatility portfolio produces the highest return. The authors proceed to devise a volatility timing strategy based on statistical tests on the slope of the volatility decile portfolio’s return profile. Volatility timing is achieved by being aggressive during strong growth periods and conservative during market downturns. Superior performance is obtained, with an additional return of 4.1% observed in the volatility timing strategy, …

Carlos Ghosn: The Rise And Fall Of An Automobile Legend, Jochen Reb, Abhijeet K. Vadera, Sin Mei Cheah
Research Collection Lee Kong Chian School Of Business
Was it politics, greed, or hubris that led to Carlos Ghosn's downfall? On December 29, 2019, disgraced auto titan Carlos Ghosn (rhymes with ‘tone’) made an audacious escape from house arrest in Tokyo, where he had been detained on financial impropriety charges. Of all the places imaginable, Ghosn hid in a huge case for musical instruments, which was then loaded onto an aeroplane as cargo. Dubbed as “one of the most brazen and well-orchestrated escape acts in recent history, involving a dizzying array of hotel meet-ups, bullet train travel, fake personas, and the chartering of a private jet”, it was …

The global COVID-19 pandemic is now in its second year, and we are fast approaching the third. The year 2021 has brought some hope that vaccination will lead to the end of the pandemic. But it has also brought a more infectious variant of COVID-19 and multiple waves of surging cases that show no immediate sign of disappearing. As the pandemic continues to impact global societies and economies, it is imperative that we study its impact to try and understand how it will affect us in both the short-term and long-term. While the longer-term impacts are still unknown, there is …
Algorithmic Transparency, Jian Sun
Algorithmic Transparency, Jian Sun
Research Collection Lee Kong Chian School Of Business
I study the optimal algorithmic disclosure in a lending market where lenders use a predictive algorithm to mitigate adverse selection. The predictive algorithm is unobservable to borrowers and uses a manipulable borrower feature as input. A regulator maximizes market efficiency by disclosing information about the statistical properties of variables embedded in the predictive algorithm to borrowers. Under the optimal disclosure policy, the posterior belief consists of two disjoint regions in which the borrower feature is more relevant and less relevant in predicting borrower quality, respectively. The optimal disclosure policy differentiates posterior lending market equilibria by the equilibrium data manipulation levels. …
Corporate Sustainability Has Failed: Digitizing Regeneration May Still Save Us, Simon J.D. Schillebeeckx
Corporate Sustainability Has Failed: Digitizing Regeneration May Still Save Us, Simon J.D. Schillebeeckx
Research Collection Lee Kong Chian School Of Business
The author proposes a focus on regeneration as a way for small carbon footprint firms (e.g., consulting, financial services firms) to make a positive sustainability impact. He highlights that service industry firms can proactively contribute to the regeneration of common pool resources, such as forests and lakes, which often become neglected or overused. What makes regeneration different compared to more traditional donations to a conservation nonprofit is the use of digital technology that enables an organization to lay claim to the ecosystem benefits it generates through its support. The digitization of benefits claims provides a transparent accounting system for environmental …

Going Far Together By Being Here Now: Mindfulness Increases Cooperation In Negotiations, Theodore Charles Masters-Waage, Jared Nai, Jochen Reb, Samantha Sim, Jayanth Narayanan, Noriko Tan
Research Collection Lee Kong Chian School Of Business
Integrating theorizing across the mindfulness and negotiation literatures, we hypothesize that mindfulness increases cooperation in negotiations. We further propose that processes of self-transcendence, self-regulation, and self-awareness mediate this effect. We test these hypotheses in five studies across different forms of cooperation, in both distributive and integrative negotiation contexts, and for both measured and experimentally induced mindfulness. In Study 1a, individuals higher on measured state mindfulness displayed greater cooperative orientation measured as preference for pareto-optimal agreements. In Study 1b, experimentally induced mindfulness led to greater cooperative orientation measured as the recall of cooperative heuristics. In Study 2, a distributive (fixed-sum) negotiation, …

Socially Responsible Corporate Customers, Rui Dai, Hao Liang, Lilian Ng
Research Collection Lee Kong Chian School Of Business
Corporate customers are an important stakeholder in global supply chains. We employ several unique international databases to test whether socially responsible corporate customers can infuse similar socially responsible business behavior in suppliers. Our findings suggest a unilateral effect on corporate social responsibility (CSR) only from customers to suppliers, an evidence further supported by exogenous variation in customers’ close-call CSR proposals and by product scandals. Customers exert influence on suppliers’ CSR through positive assortative matching and their decision-making process. Enhanced collaborative CSR efforts help improve operational efficiency and firm valuation of both customers and suppliers but increase only the customers’ future …

In a digital economy characterized by high volumes of information and ideas, many of which could be contradictory to one another, employees high in dialectical thinking should be well poised to connect disparate ideas to generate creative solutions for business problems. Yet, it is unclear whether dialectical thinking as a creativity-relevant skill can be realized in naturalistic workplace settings, given past mixed findings and the lack of field studies. We propose that supervisors’ leadership styles are important moderators that can unlock employees’ creativity potential in dialectical thinking. Additionally, we compare the activating effect of transformational leadership and the inhibiting effect …

Joint News, Attention Spillover, And Market Returns Predictability, Li Guo, Lin Peng, Yubo Tao, Jun Tu
Research Collection Lee Kong Chian School Of Business
We analyze over 2.6 million news articles and propose a novel measure of joint news coverage of firms. The measure strongly and negatively predicts market returns, with a monthly R-squared of 3.93% in sample and 6.52% out of sample. The relation is causal, robust to existing predictors, and is especially strong when market uncertainty is high or when market frictions are large. At the firm level, joint news coverage is associated with a 20.3% increase in EDGAR downloads by new IPs from the investor bases of the other covered firms. Our evidence suggests that joint news triggers investor attention spillover …
Platform-Dependent Entrepreneurs: Participants In An Expanding Universe Of Platforms?, F. Ted Tschang
Platform-Dependent Entrepreneurs: Participants In An Expanding Universe Of Platforms?, F. Ted Tschang
Research Collection Lee Kong Chian School Of Business
The article Platform-dependent entrepreneurs: Power asymmetries, risks, and strategies in the platform economy drew on the intermediary business model to review the damaging actions that platform firms may employ with entrepreneurs. This exchange argues that platform firms may treat entrepreneurs differently on other platform types-particularly ones where complex relationships may cause participants and platforms to become mutually dependent, or where the platform's position depends less on extracting revenue directly from participants. I suggest that particular business models might facilitate the use of alternative strategic actions that are more benign toward entrepreneurs. These situations can determine additional boundary conditions for this …

Esg And The Market Return, Ran Chang, Liya Chu, Jun Tu, Bohui Zhang, Guofu Zhou
Research Collection Lee Kong Chian School Of Business
We propose an environmental, social, and governance (ESG) index. We find that it has significant power in predicting the stock market risk premium, both in- and out-of-sample, and delivers sizable economic gains for mean-variance investors in asset allocation. Although the index is extracted by using the PLS method, its predictability is robust to using alternative machine learning tools. We find further that the aggregate of environmental variables captures short-term forecasting power, while that of social or governance captures long-term. The predictive power of the ESG index stems from both cash flow and discount rate channels.

Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low
Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low
Research Collection Lee Kong Chian School Of Business
Capacity sharing among neighboring terminals offer a means to meet increasing or unexpected demand for cargo-handling without additional capital investment. This study proposes a model for capacity requirement planning of major resources, such as quay cranes (QCs), storage space, and gate, in multiterminal port operations where demand is time dependent. A resource profile simulation is run to generate random events across the terminals and estimate the capacity requirement in the form of workload distributions on port resources over time-shifts. The effects on workload requirement, arising from multiterminal cooperation, are subsequently evaluated in consideration of different container flows among terminals. Experimental …

We build on recent examinations questioning the quality of online information about probiotic products by studying the themes of content, detecting virtual communities and identifying key influencers in social media using data science techniques. We conducted topic modelling (n = 36,715 tweets) and longitudinal social network analysis (n = 17,834 tweets) of probiotic chatter on Twitter from 2009–17. We used Latent Dirichlet Allocation (LDA) to build the topic models and network analysis tool Gephi for building yearly graphs. We identified the top 10 topics of probiotics-related communication on Twitter and a constant rise in communication activity. However the number of …

Air Pollution, Behavioral Bias, And The Disposition Effect In China, Jennifer (Jie) Li, Massimo Massa, Hong Zhang, Jian Zhang
Research Collection Lee Kong Chian School Of Business
Inspired by the recent health science findings that air pollution affects mental health and cognition, we examine whether air pollution can intensify the cognitive bias observed in the financial markets. Based on a proprietary data set obtained from a large Chinese mutual fund family consisting of complete trading information for more than 773,198 ac-counts in 247 cities, we find that air pollution significantly increases investors' disposition effects. Analysis based on two plausible exogenous variations in air quality (the vast dissi-pation of air pollution caused by strong winds and the Huai River policy) supports a causal interpretation. Mood regulation provides a …

Most managers understand that empowering employees to voice their opinions can help companies innovate and uncover their own shortcomings. However, this understanding does not seem to translate into action. Research shows that over 85% of employees remain silent on crucial matters because they worry about being viewed negatively. How can managers encourage employees to speak their minds at work? The authors’ new research identified a novel method to encourage employees to exercise their voice: creating a company culture that emphasizes the idea of choice. They found that employees were more likely to share their ideas and opinions at a company …

We Are On The Way: Analysis Of On-Demand Ride-Hailing Systems, Guiyun Feng, Guangwen Kong, Zizhuo Wang
Research Collection Lee Kong Chian School Of Business
Problem definition: Recently, there has been a rapid rise of on-demand ride-hailing platforms, such as Uber and Didi, which allow passengers with smartphones to submit trip requests and match them to drivers based on their locations and drivers’ availability. This increased demand has raised questions about how such a new matching mechanism will affect the efficiency of the transportation system—in particular, whether it will help reduce passengers’ average waiting time compared with traditional street-hailing systems. Academic/practical relevance: The on-demand ride-hailing problem has gained much academic interest recently. The results we find in the ride-hailing system have a significant …
