An Inertial Triple-Projection Algorithm For Solving The Split Feasibility Problems, Yazheng Dang, Marcus Ang, Jie Sun Mar 2023

An Inertial Triple-Projection Algorithm For Solving The Split Feasibility Problems, Yazheng Dang, Marcus Ang, Jie Sun

Research Collection Lee Kong Chian School Of Business

This paper proposes a new inertial triple-projection algorithm for solving the split feasibility problem (SFP).The process of projections is divided into three parts. Each part adopts a different variable stepsize to obtain its projection point, which is different from the existing extragradient methods. Flexible rules are employed for selecting the stepsizes and the inertial technique is used for improving the convergence. Convergence results are proven. Numerical experiments show that the proposed method converges more quickly than the general CQ algorithm.


Impact Of Geographical Diversification And Limited Attention On Private Equity Fund Returns, Victor Ong Feb 2023

Impact Of Geographical Diversification And Limited Attention On Private Equity Fund Returns, Victor Ong

Research Collection Lee Kong Chian School Of Business

This article analyzes the effect of geographical diversification on global private equity (PE) fund returns. We find that there is a negative correlation between geographical diversification and PE fund returns. To establish the causality between geographical diversification and PE fund returns, we employ an instrumental variable analysis where the instrument used is the stock market capitalization of the host country where the PE fund is based. Our results apply to Net IRR, TVPI and DPI as dependent variables used to proxy for PE fund returns in the main regression model. A one standard deviation increase in geographical diversification results in …


R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee Jan 2023

R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee

Research Collection School Of Economics

This paper investigates the extent to which a regulatory environment for R&D subsidies shapes the magnitude and direction of R&D subsidies set by a government and consequent innovation paths. When the WTO adopted a permissive regulatory environment, we find that the Korean government increased R&D subsidies significantly (89.21%) and selectively so for firms and industries with higher returns. Recipient firms conducted less basic research and more development research. Improvements in innovations were mostly incremental and minor. However, such changes did not persist once the WTO switched to a restrictive regulatory environment. Our findings show that the regulatory environment imposed by …

Presidential Economic Approval Rating And The Cross-Section Of Stock Returns, Zilin Chen, Zhi Da, Dashan Huang, Liyao Wang Jan 2023

Presidential Economic Approval Rating And The Cross-Section Of Stock Returns, Zilin Chen, Zhi Da, Dashan Huang, Liyao Wang

Research Collection Lee Kong Chian School Of Business

We construct a monthly presidential economic approval rating (PEAR) index from 1981 to 2019, by averaging ratings on the president’s handling of the economy across various national polls. In the cross-section, stocks with high betas to changes in the PEAR index significantly under-perform those with low betas by 1.00% per month in the future, on a risk-adjusted basis. The low PEAR beta premium persists up to one year, and is present in various sub-samples and even in other G7 countries. PEAR beta dynamically reveals a firm’s perceived alignment to the incumbent president’s economic policies and investors seem to misprice such …


An Exponential Cone Programming Approach For Managing Electric Vehicle Charging, Li Chen, Long He, Yangfang (Helen) Zhou Jan 2023

An Exponential Cone Programming Approach For Managing Electric Vehicle Charging, Li Chen, Long He, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

To support the rapid growth in global electric vehicle adoption, public charging of electric vehicles is crucial. We study the problem of an electric vehicle charging service provider, which faces (1) stochastic arrival of customers with distinctive arrival and departure times, and energy requirements as well as (2) a total electricity cost including demand charges, costs related to the highest per-period electricity used in a finite horizon. We formulate its problem of scheduling vehicle charging to minimize the expected total cost as a stochastic program (SP). As this SP is large-scale, we solve it using exponential cone program (ECP) approximations. …


The Livingston Survey 2022, S. Anderson, B. Bovino, M. Brown, Thomas Lam, Et Al Dec 2022

The Livingston Survey 2022, S. Anderson, B. Bovino, M. Brown, Thomas Lam, Et Al

Sim Kee Boon Institute for Financial Economics

The 16 participants in the December Livingston Survey weakened their forecasts for real GDP growth, compared with their projections in the June 2022 survey. The forecasters, who are surveyed by the Federal Reserve Bank of Philadelphia twice a year, expect 2.0 percent annualized growth in real GDP during the second half of 2022. They project 0.4 percent annualized growth over the first half of 2023. The forecasters predict that real GDP will continue to decline and reach -1.0 percent annualized growth in the second half of 2023.


Does Abstract Thinking Facilitate Information Processing? Evidence From Financial Analysts, Frank Weikai Li, Rong Wang, Yang Yu, Gloria Yang Yu Dec 2022

Does Abstract Thinking Facilitate Information Processing? Evidence From Financial Analysts, Frank Weikai Li, Rong Wang, Yang Yu, Gloria Yang Yu

Research Collection Lee Kong Chian School Of Business

We study whether abstract thinking – an essential cognitive trait established by psychological and neuroscientific studies – facilitates analysts’ information processing. Exploiting analysts’ questions during earnings calls, we construct an Abstract Thinking Index (ATI) that measures their tendency to involve abstract words, logical reasoning, broader topics, and future outlooks. We find that abstract thinking improves analysts’ forecast accuracy and recommendation informativeness. Consistent with abstract thinking featuring identifying central characteristics and comprehending intangible things, ATI has stronger effects for firms with fundamentals co-moving more with peers and less tangible information. Additional analyses suggest that ATI captures analysts’ cognitive traits rather than …


Pickup And Multi-Delivery Problem With Time Windows, Pham Tuan Anh, Aldy Gunawan, Vincent F. Yu, Tuan C. Chau Dec 2022

Pickup And Multi-Delivery Problem With Time Windows, Pham Tuan Anh, Aldy Gunawan, Vincent F. Yu, Tuan C. Chau

Research Collection School Of Computing and Information Systems

This paper addresses a new variant of Pickup and Delivery Problem with Time Windows (PDPTW) for enhancing customer satisfaction. In particular, a huge number of requests is served in the system, where each request includes a pickup node and several delivery nodes instead of a pair of pickup and delivery nodes. It is named Pickup and Multi-Delivery Problem with Time Windows (PMDPTW). A mixed-integer programming model is formulated with the objective of minimizing total travel costs. Computational experiments are conducted to test the correctness of the model with a newly generated benchmark based on the PDPTW benchmark instances. Results show …


What Should Streamers Communicate In Livestream E-Commerce? The Effects Of Social Interactions On Live Streaming Performance, Danyang Song, Xi Chen, Zhiling Guo, Xiao Liu Liu, Ruijin. Jin Dec 2022

What Should Streamers Communicate In Livestream E-Commerce? The Effects Of Social Interactions On Live Streaming Performance, Danyang Song, Xi Chen, Zhiling Guo, Xiao Liu Liu, Ruijin. Jin

Research Collection School Of Computing and Information Systems

Compared with traditional e-commerce, livestreaming e-commerce is characterized by direct and intimate communication between streamers and consumers that stimulates instant social interactions. This study focuses on streamers’ three types of information exchange (i.e., product information, social conversation, and social solicitation) and examines their roles in driving both short-term and long-term livestreaming performance (i.e., sales and customer base growth). We find that the informational role of product information (nonpromotional and promotional) is beneficial not only to sales performance, but also to the growth of the customer base. We also find that social conversation has a relationship-building effect that positively impacts both …


The Value Of Fiduciary Duties: Evidence From En Bloc Sales In Singapore, Jianfeng Hu, Kelvin F. K. Low, Wei Zhang Dec 2022

The Value Of Fiduciary Duties: Evidence From En Bloc Sales In Singapore, Jianfeng Hu, Kelvin F. K. Low, Wei Zhang

Research Collection Lee Kong Chian School Of Business

This paper examines the impact of fiduciary duties on collective asset sales in the case of owners acting as delegates for other owners, thereby potentially inducing conflicts of interests. Our identification strategy exploits a unique legal shock in Singapore, which established fiduciary duties in those transactions in the real estate market known colloquially as en bloc sales. The imposition of fiduciary duties caused the price premium of units sold via en bloc sales to increase over units ineligible for en bloc sale, as well as over units that, although eligible for en bloc sale, are sold individually. In addition, this …


Learning From Manipulable Signals, Mehmet Ekmekci, Leandrro Gorno, Lucas Maestri, Jian Sun, Dong Wei Dec 2022

Learning From Manipulable Signals, Mehmet Ekmekci, Leandrro Gorno, Lucas Maestri, Jian Sun, Dong Wei

Research Collection Lee Kong Chian School Of Business

We study a dynamic stopping game between a principal and an agent. The agent is privately informed about his type. The principal learns about the agent’s type from a noisy performance measure, which can be manipulated by the agent via a costly and hidden action. We fully characterize the unique Markov equilibrium of this game. We find that terminations/ market crashes are often preceded by a spike in (expected) performance. Our model also predicts that, due to endogenous signal manipulation, too much transparency can inhibit learning. As the players get arbitrarily patient, the principal elicits no useful information from the …


Avoiding Bias In The Search For Implicit Bias, Wilson Cyrus-Lai, Warren Tierney, Christilene Du Plessis, My Nguyen, Michael Schaerer, Elena Giulia Clemente, Eric Luis Uhlmann Nov 2022

Avoiding Bias In The Search For Implicit Bias, Wilson Cyrus-Lai, Warren Tierney, Christilene Du Plessis, My Nguyen, Michael Schaerer, Elena Giulia Clemente, Eric Luis Uhlmann

Research Collection Lee Kong Chian School Of Business

To revitalize the study of unconscious bias, Gawronski, Ledgerwood, and Eastwick (this issue) propose a paradigm shift away from implicit measures of intergroup attitudes and beliefs. Specifically, researchers should capture discriminatory biases and demonstrate that participants are unaware of the influence of social category cues on their judgments and actions. Individual differences in scores on implicit measures will be useful to predict and better understand implicitly prejudiced behaviors, but the latter should be the collective focus of researchers interested in unconscious biases against social groups.


Board Governance Of Strategic Change: An Assessment Of The Literature And Avenues For Future Research, Patricia Klamer, Qiwen Yu, Toru Yoshikawa, Michael Hitt Nov 2022

Board Governance Of Strategic Change: An Assessment Of The Literature And Avenues For Future Research, Patricia Klamer, Qiwen Yu, Toru Yoshikawa, Michael Hitt

Research Collection Lee Kong Chian School Of Business

Boards of directors play a central role in governing corporate strategic change.We systematically review corporate governance research on strategic changepublished over the past 40 years, differentiating between strategic change typesand board characteristics. We identify three developments: a focus on specificstrategic change types, board composition and structure, and North Americanlisted firms as a dominant study context. Yet, our analysis of the literature showsthat research on board governance of interrelated strategic changes, on differ-ent board roles and behaviour, and on the governance of strategic changes acrossdifferent contexts remains underdeveloped. To address these research gaps, wesuggest three future research avenues: (1) examining how …


Governance, Risk And Compliance (Grc) In Digital Transformation: Investor Views, Clarence Goh, Yuanto Kusnadi, Gary Pan, Poh Sun Seow Nov 2022

Governance, Risk And Compliance (Grc) In Digital Transformation: Investor Views, Clarence Goh, Yuanto Kusnadi, Gary Pan, Poh Sun Seow

Research Collection School Of Accountancy

Companies are embracing digital transformation to enhance their competitiveness. Existing studies show that it is important for companies to manage the governance, risk, and compliance (GRC) aspects of their digital transformation initiatives. While companies are increasingly understanding the importance of the role of GRC in digital transformation, it is unclear from the investors’ views. Thus, this study examines whether investors are placing importance on the role of GRC in digital transformation for their investment decisions. The results show that investors care about the GRC aspects of digital transformation initiatives undertaken by companies. The findings of this study are consistent with …


More Voices Persuade: The Attentional Benefits Of Voice Numerosity, Hannah H. Chang, Anirban Mukherjee, Amitava Chattopadhyay Oct 2022

More Voices Persuade: The Attentional Benefits Of Voice Numerosity, Hannah H. Chang, Anirban Mukherjee, Amitava Chattopadhyay

Research Collection Lee Kong Chian School Of Business

The authors posit that in an initial exposure to a broadcast video, hearing different voices narrate (in succession) a persuasive message encourages consumers’ attention and processing of the message, thereby facilitating persuasion; this is referred to as “the voice numerosity effect.” Across four studies (plus validation and replication studies)—including two large-scale, real-world datasets (with more than 11,000 crowdfunding videos and over 3.6 million customer transactions, and more than 1,600 video ads) and two controlled experiments (with over 1,800 participants)—the results provide support for the hypothesized effect. The effect (1) has consequential, economic implications in a real-world marketplace, (2) is more …

Investigating Accessibility Challenges And Opportunities For Users With Low Vision Disabilities In Customer-To-Customer (C2c) Marketplaces, Bektur Ryskeldiev, Kotaro Hara, Mariko Kobayashi, Koki Kusano Oct 2022

Investigating Accessibility Challenges And Opportunities For Users With Low Vision Disabilities In Customer-To-Customer (C2c) Marketplaces, Bektur Ryskeldiev, Kotaro Hara, Mariko Kobayashi, Koki Kusano

Research Collection School Of Computing and Information Systems

Inaccessible e-commerce websites and mobile applications exclude people with visual impairments (PVI) from online shopping. Customer-to-customer (C2C) marketplaces, a form of e-commerce where trading happens not between businesses and customers but between customers, could pose a unique set of challenges in the interactions that the platform brings about. Through online questionnaire and remote interviews, we investigate problems experienced by people with low vision disabilities in common C2C scenarios. Our study with low vision participants (N = 12) reveal both previously known general accessibility issues (e.g., web and mobile interface accessibility) and C2C specific accessibility issues (e.g., inability to confirm item …


What Machines Can't Do (Yet) In Real Work Settings, Thomas H. Davenport, Steven M. Miller Oct 2022

What Machines Can't Do (Yet) In Real Work Settings, Thomas H. Davenport, Steven M. Miller

Research Collection School Of Computing and Information Systems

AI systems may perform well in the research lab or under highly controlled application settings, but they still needed human help in the types of real world work settings we researched for a new book, Working With AI: Real Stories of Human-Machine Collaboration. Human workers were very much in evidence across our 30 case studies. In this article, we use those examples to illustrate our list of AI-enabled activities that still require human assistance. These are activities where organizations need to continue to invest in human capital, and where practitioners can expect job continuity for the immediate future


Field Experiments In Operations Management, Yang Gao, Meng Li, Shujing Sun Oct 2022

Field Experiments In Operations Management, Yang Gao, Meng Li, Shujing Sun

Research Collection School Of Computing and Information Systems

While the field experiment is a powerful and well-established method to investigate causal relationships, operations management (OM) has embraced this methodology only in recent years. This paper provides a comprehensive review of the existing OM literature leveraging field experiments and serves as a one-stop guide for future application of field experiments in the OM area. We start by recapping the characteristics that distinguish field experiments from other common types of experiments and organizing the relevant OM studies by topic. Corresponding to the commonly overlooked issues in field experiment-based OM studies, we then provide a detailed roadmap, ranging from experimental design …

Misunderstood Menu Metrics: Side-Length Food Sizing Leads To Quantity Underestimation And Overeating, Thomas Allard, Stefano Puntoni Oct 2022

Misunderstood Menu Metrics: Side-Length Food Sizing Leads To Quantity Underestimation And Overeating, Thomas Allard, Stefano Puntoni

Research Collection Lee Kong Chian School Of Business

This research highlights consumers' failure to understand food sizing communicated using side-length metrics (e.g., 12-inch pizza, 8-inch cake, 2-inch cookie), which are ubiquitous in menus and online interfaces. A series of studies show that describing food size options using side-length metrics leads to food quantity underestimation and food intakes misaligned with consumers' objectives. This robust effect arises because of a linearization heuristic where people do not adequately adjust for the exponential difference in the surface area associated with linear changes in side-length metrics. Choice architecture interventions that replace side-length information with metrics varying linearly with quantities (e.g., surface area, numbers …


Networking Fast And Slow: The Role Of Speed In Tie Formation, Julia Brennecke, Gokhan Ertug, Tom Elfring Oct 2022

Networking Fast And Slow: The Role Of Speed In Tie Formation, Julia Brennecke, Gokhan Ertug, Tom Elfring

Research Collection Lee Kong Chian School Of Business

Growing interest in network dynamics has led to insights about patterns of network change, drivers of tie formation, and the temporal unfolding of the consequences of networks. To this area of inquiry, we introduce networking speed – the time it takes for individuals to form a network tie – as an important but so far largely overlooked aspect. We develop a theory of networking speed that explains how different catalysts enable professionals to introduce variation into the speed with which they form interpersonal network ties. We discuss how such variation in the speed with which ties have been formed influences …


Artificial Intelligence, Consumers, And The Experience Economy, Hannah H. Chang, Anirban Mukherjee Oct 2022

Artificial Intelligence, Consumers, And The Experience Economy, Hannah H. Chang, Anirban Mukherjee

Research Collection Lee Kong Chian School Of Business

The term Artificial Intelligence (AI) was first used by McCarthy, Minsky, Rochester, and Shannon in a proposal for a summer research project in 1955 (Solomonoff, 1985). It is widely and commonly defined to be “the science and engineering of making intelligent machines” (McCarthy, 2006). Recent technological advances and methodological developments have made AI pervasive in new marketing offerings, ranging from self-driving cars, intelligent voice assistants such as Amazon’s Alexa, to burger-making robots at restaurants and rack-moving robots inside warehouses such as Amazon’s family of robots (Kiva, Pegasus, Xanthus) and delivery drones. There is optimism, and perhaps even over-optimism, of the …

Using Machine Learning To Extract Insights From Consumer Data, Hannah H. Chang, Anirban Mukherjee

Research Collection Lee Kong Chian School Of Business

Advances in digital technology have led to the digitization of everyday activities of billions of people around the world, generating vast amounts of data on human behavior. From what people buy, to what information they search for, to how they navigate the social, digital, and physical world, human behavior can now be measured at a scale and level of precision that human history has not witnessed before. These developments have created unprecedented opportunities for those interested in understanding observable human behavior–social scientists, businesses, and policymakers—to (re)examine theoretical and substantive questions regarding people’s behavior. Moreover, technology has led to the emergence …


Local, Yet Global: Implications Of Caste For Mnes And International Business, Hari Bapuji, Snehanjali Chrispal, Balagopal Vissa, Gokhan Ertug Oct 2022

Local, Yet Global: Implications Of Caste For Mnes And International Business, Hari Bapuji, Snehanjali Chrispal, Balagopal Vissa, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

Caste is an informal institution that influences socioeconomic action in many contexts. It is becoming increasingly evident that international business research, practice, and policy need to programmatically address caste. To facilitate this endeavour, we review the limited research in IB that has addressed caste, and theorize caste as a distinct informal institution by distinguishing it from systems of stratification like race, class, and gender. In addition, we propose a parsimonious framework to highlight the implications of caste for Indian and non-Indian MNEsin their Indian and global operations. In doing this, we focus on implications with respect to the internal organization …


The Mutual Constitution Of Culture And Psyche: The Bidirectional Relationship Between Individuals’ Perceived Control And Cultural Tightness-Looseness, Anyi Ma, Krishna Savani, Fangzhou Liu, Kenneth Tai, Aaron C. Kay Oct 2022

The Mutual Constitution Of Culture And Psyche: The Bidirectional Relationship Between Individuals’ Perceived Control And Cultural Tightness-Looseness, Anyi Ma, Krishna Savani, Fangzhou Liu, Kenneth Tai, Aaron C. Kay

Research Collection Lee Kong Chian School Of Business

According to the theory of mutual constitution of culture and psyche, just as culture shapes people, individuals’ psychological states can influence culture. We build on compensatory control theory, which suggests that low personal control can lead people to prefer societal systems that impose order, to examine the mutual constitution of personal control and cultural tightness. Specifically, we tested whether individuals’ lack of personal control increases their preference for tighter cultures as a means of restoring order and predictability, and whether tighter cultures in turn reduce people’s feelings of personal control. Seven studies (five preregistered) with participants from the United States, …


Shrinking Factor Dimension: A Reduced-Rank Approach, Dashan Huang Oct 2022

Shrinking Factor Dimension: A Reduced-Rank Approach, Dashan Huang

Research Collection Lee Kong Chian School Of Business

We propose a reduced-rank approach (RRA) to reduce a large number of factors to a few parsimonious ones. In contrast to PCA and PLS, the RRA factors are designed to explain the cross section of stock returns, not to maximize factor variations or factor covariances with returns. Out of 70 factor proxies, we find that five RRA factors outperform the Fama-French (2015) five factors for pricing target portfolios, but performs similarly for pricing individual stocks. Our results suggest that existing factor proxies do not provide enough new information at the stock level beyond the Fama-French (2015) five factors.
