Brothers, Sisters, And Support To Older Parents: Separate Spheres Across And Within Support Types?, Christine Ho, Kathleen Mcgarry

Research Collection School Of Economics

Parents in many countries exhibit a strong preference for sons over daughters; a preference that is often observed regarding transfers to children. Here, we ask whether son preference also drives differences in behavior regarding transfers from sons and daughters. We use data from the China Health and Retirement Longitudinal Study (CHARLS) to examine the patterns of giving to parents and find strong evidence of such differentiation. Coresidential support comes almost exclusively from sons as do large transfers, while daughters are more likely to make small transfers. Moreover, crowding-out of financial transfers by siblings occurs primarily within gender: sons give less …

Disagreement In Market Index Options, Guilherme Salome, George Tauchen, Jia Li

Research Collection School Of Economics

We generate new evidence on disagreement among traders in the S&P 500 options market from high-frequency intraday price and volume data. Inference on disagreement is based on a model where investors observe public information but agree to disagree on its interpretation; disagreement among investors is captured by the volume–volatility elasticity. For options, there are two natural variables related to disagreement: moneyness and tenor, which we relate to disagreement about the distribution of the market index at different quantiles and times. The estimated volume–volatility elasticity equals unity for options near the money and close to expiration, which is consistent with the …

Equity In Commerce: Too Much And Too Little?, Man Yip

Research Collection Yong Pung How School Of Law

The interaction and clash between equity and commerce have attracted much attention from judges and academics in recent years. Commercial lawyers may complain about equity introducing uncertainty into commercial endeavours and at times, (mis-)applying the ‘moral standards of the vicarage’ to actors in commercial dealings. However, the objections are not directed at all aspects of equity, but are usually addressed to some ‘disfavoured parts of it’, such as the creation of a new obligation or discretionary remedies. On the other hand, from the perspective of equity lawyers, equity’s interplay with commerce may lead to the contractualisation or commercialisation of equitable …

The Influence Of Subjective Socioeconomic Status On Executive Functions In Middle-Aged And Older Adults, Yu Ping Wong, Hwajin Yang

Research Collection School of Social Sciences

Subjective socioeconomic status (SES) has been shown to influence both psychological and biological outcomes. However, less is known about whether its influence extends to cognitive outcomes. We examined the relation between subjective SES and executive functions (EF)—a set of cognitive control processes—and its underlying mechanisms. By analyzing a nationally representative cohort of middle-aged and older adults (age 40–80) from the MIDUS 2 National Survey and Cognitive Project, we tested a serial mediation model with sense of control and health as sequential mediators. Using structural equation modeling, we found that subjective SES is indirectly related to EF via sense of control …

Ethical Leadership And Employee Unethical Behavior: A Dual-Processing Model, Chenjing Gan, Chi-Ying Cheng, Yandong Chai, Linbo Yang

Research Collection School of Social Sciences

Purpose – This study seeks to apply a dual-processing model to understand how ethical leadership prohibits employee unethical behavior through both employee deontic justice and distributive justice. Design/methodology/approach – A survey research was conducted with 62 supervisors and 244 subordinates of 17 firms collected at 2 time points separated by approximately 3 weeks in People’s Republic of China. Findings – A multilevel modeling analysis was used to test the dual-processing model. The results showed that both employee deontic justice (moral intuition process) and distributive justice (deliberate reasoning process) significantly mediate the negative relationship between ethical leadership and employee unethical behavior. …

Multigenerational Coresidence And Parental Time In Developmental Childcare In China, Cheng Cheng, Menghan Zhao

Research Collection School of Social Sciences

Previous literature has examined how multigenerational coresidence changes parental time in primary childcare. However, much less is known about how coresidence may affect the amount of time parents invest in developmental childcare, which is crucial for children’s education and life chances. Using longitudinal data from the China Family Panel Studies 2010-2018, we examine how parental time investment in developmental childcare varies by household structure and parental and grandparental education. Results suggest that coresidence with maternal grandparents increases mothers’ time in developmental childcare among children with high-educated parents. Moreover, the positive effect of matrilocal residence on maternal time investment is greatest …

Desire For Social Status Affects Marital And Reproductive Attitudes: A Life History Mismatch Perspective, Amy J. Lim, Norman P. Li, Zoi Manesi, Steven L. Neuberg, Mark Van Vugt, Andrea L. Meltzer, Kenneth Tan

Research Collection School of Social Sciences

Modern low fertility is an unresolved paradox. Despite the tremendous financial growth and stability in modern societies, birth rates are steadily dropping. Almost half of the world's population lives in countries with below-replacement fertility and is projected for a continued decline. Drawing on life history theory and an evolutionary mismatch perspective, we propose that desire for social status (which is increasingly experienced by individuals in industrialized, modern societies) is a key factor affecting critical reproductive preferences. Across two experimental studies (total N = 719), we show that activating a desire for status can lead people to prefer reproductive tradeoffs that …

Chinese Global Orders: Socialism, Tradition, And Nation In China-Russia Relations, William A. Callahan

Research Collection School of Social Sciences

While many use rational IR theory to explain Chinese foreign policy behavior, this paper follows global IR to employ interpretivist theory to examine how Chinese elites understand their country’s role in the world. In particular, it explores the Chinese global order ideas of socialism, tradition, and nation through a comparative analysis of how they work in China–Russia relations, especially after China’s 20th Communist Party Congress in 2022. The first section presents a critical analysis of the realist understanding of the China–Russia–U.S. strategic triangle. It argues that the socialist concept of “united front work” better explains Chinese (and Russian) policy in …

Understanding The Dilemma Of Chinese Farmers' Cooperatives: A Chayanov Perspective, Zhanping Hu, Qian Forrest Zhang, John A. Donaldson

Research Collection School of Social Sciences

Chayanov’s The Theory of Peasant Cooperatives has been read as a work advocating the viability and even superiority of peasant cooperatives as compared to capitalist farming, we contend that it actually provides the strongest analysis of why most peasant cooperatives are doomed to fail. Chayanov identified five major obstacles peasant cooperatives face, and those obstacles push cooperatives into a vicious circle. Without powerful state support, it is nearly impossible to break the vicious circle. Based on 65 typical cooperatives from 20 provinces, this paper illustrates how these obstacles that Chayanov identified are precisely the reasons why almost all the cooperatives …

Growing Up Under Mao And Deng: On The Ideological Determinants Of Corporate Policies, Hao Liang, Rong Wang, Haikun Zhu

Research Collection Lee Kong Chian School Of Business

Historically, economic activities have been organized around certain ideologies. We investigate the impact of politicians’ ideology on corporate policies by exploring a unique setting of ideological change—China from Mao to Deng around the 1978 economic reform—in a regression discontinuity framework. We find that the age discontinuity of politicians around 18 years old in 1978, who had already joined the Chinese Communist Party (CCP) or joined soon thereafter and later became municipal paramount leaders, has had a lasting effect on contemporary firm- and city-level policies. In particular, firms in cities with mayors that joined the CCP under the ideological regime of …

Mindfully Outraged: Mindfulness Increases Deontic Retribution For Third-Party Injustice, Adam A. Kay, Theodore Charles Masters-Waage, Jochen Reb, Pavlos A. Vlachos

Research Collection Lee Kong Chian School Of Business

Mindfulness is known to temper negative reactions by both victims and perpetrators of injustice. Accordingly, critics claim that mindfulness numbs people to injustice, raising concerns about its moral implications. Exam-ining how mindful observers respond to third-party injustice, we integrate mindfulness with deontic justice theory to propose that mindfulness does not numb but rather enlivens people to injustice committed by others against others. Results from three studies show that mindfulness heightens moral outrage in witnesses of injustice, particularly when the injustice is only moderate. Although these findings did not replicate with a mindfulness induction, post-hoc analysis in a fourth study reveals …

Leader Apology In The Employee-Organization Relationship: The Roles Of Subordinate Power Distance Belief And Leader Competence, Xingyu Wang, Xueqi Wen, Zihan Liu, Yuzhuo Jiang, Mingyun Huai

Research Collection Lee Kong Chian School Of Business

According to the organizational support theory, leaders’ words and deeds are not only the products of their own will but also a reflection of organizations’ standpoints. We thus focus on leader apology in the case of organizational transgressions and predict that leaders’ apologetic acts are likely to influence employees’ organizationoriented attitudes and behaviors. Specifically, leader apology is hypothesized to positively influence employees’ perception of organizational support, which in turn, is positively associated with employees’ helping and risk taking behavior. Furthermore, drawing upon the organizational support theory that delineates the discretion and value perceived in the employee-organization relationship, we further propose …

Measuring The Learning Effectiveness Of Two Courses In A Program In Accounting Data And Analytics, Clarence Goh, Duan Ning, Magdeleine Lew, Gary Pan, Poh Sun Seow

Research Collection School Of Accountancy

Driven by rapid technological innovation, information technology (IT) is expected to significantly alter the way that accountants work. However, both accounting researchers and practitioners have observed a shortage of accounting professionals who currently possess the relevant technology skillsets to exploit technological advances. In response, the School of Accountancy of a Singapore-based university launched a second major program in Accounting Data and Analytics in 2018. In this study, we examine the learning effectiveness of two courses – Business Data Management and Data Modelling & Visualization – offered as part of the program. Overall, our results suggest that the courses are effective …

How Transformational Leadership Transforms Followers’ Affect And Work Engagement, Benjamin Bader, Michael Gielnik, Ronald Bledow

Research Collection Lee Kong Chian School Of Business

How do episodes of transformational leadership transform followers? To address this question, we build on theories of affective events and affect regulation and develop a research model that explicates a mechanism of the transformation process implicit in transformational leadership theory. Specifically, the model explains how experiencing episodes of transformational leadership transforms (i.e., changes) followers’ positive affect and eventually their work engagement by fulfilling followers’ basic psychological needs. We tested our model in two independent longitudinal samples using daily and weekly measurement designs with 214 (N = 75) and 147 (N = 54) lagged observations, respectively. In support of our model, …

Singapore Management University (Smu): Tracking The Strategy Evolution Of A Start-Up University, Michelle P. Lee, Howard Thomas, Alex Wilson

Research Collection Lee Kong Chian School Of Business

The year 2020 marked the 20th anniversary of the Singapore Management University (SMU). SMU exists in an ecosystem for higher education that is quite unlike what one might find in other parts of the world. The supportive and stable environment the Singapore government provided in terms of its funding and policies meant a more predictable environment within which a university can make long-range planning. Singapore's development since its independence in 1965 has been undergirded by the belief that a strong educational system is the backbone of the country's economic development. The Era of Evolution is a story of both implementation …

Experimental Assessment Of Thermal And Acoustics Interactions On Occupant Comfort In Mixed-Mode Buildings, Yuzhen Peng, Nogista Antanuri, Siu-Kit Lau, Bahador Jebelli, Kardinal Steve Jusuf, Clayton Miller, Ting Yi Teo, Xuan Yun Chua, Adrian Chong

Research Collection College of Integrative Studies

Mixed-mode buildings use natural ventilation (NV) through operable building envelopes (e.g., windows) and mechanical air-conditioning (AC) systems to condition indoor spaces with the goal of energy savings without compromising occupant comfort requirements. As a result, occupants within such buildings experience different thermal and acoustic conditions. In mixed-mode buildings, however, there is no clear guideline on assessing or predicting occupants’ thermal perception (e.g., thermal sensation and acceptability) and the interaction effects between thermal and acoustic comfort. This study investigates thermal and acoustic comfort as well as their interaction effects in mixed-mode buildings under NV and AC modes. A field study was …

Lessons Learned From The Hospital To Home Community Care Program In Singapore And The Supporting Ai Multiple Readmissions Prediction Model, John Abisheganaden, Kheng Hock Lee, Lian Leng Low, Eugene Shum, Han Leong Goh, Christine Gia Lee Ang, Adny An Ta Wee, Steven M. Miller

Research Collection School Of Computing and Information Systems

In a prior practice and policy article published in Healthcare Science, we introduced the deployed application of an artificial intelligence (AI) model to predict longer-term inpatient readmissions to guide community care interventions for patients with complex conditions in the context of Singapore's Hospital to Home (H2H) program that has been operating since 2017. In this follow on practice and policy article, we further elaborate on Singapore's H2H program and care model, and its supporting AI model for multiple readmission prediction, in the following ways: (1) by providing updates on the AI and supporting information systems, (2) by reporting on customer …

Optimization Of Station-Skip In A Cyclic Express Subway Service, Jingfeng Yang, Hai Wang, Jiangang Jin

Research Collection School Of Computing and Information Systems

With rapid population growth and increasing demand for urban mobility, metropolitan areas such as Singapore, Tokyo, and Shanghai are increasingly dependent on public transport systems. Various strategies are proposed to improve the service quality and capacity of bus and subway systems. Express trains—i.e., trains that skip certain stations—are commonly used because they can travel at higher speeds, potentially reduce travel time, and serve more passengers. In this paper, we study cyclic express subway service (CESS), in which express trains provide routine transport service with cyclic (periodic) station-skip patterns that can be used in daily service. We propose an exact Mixed …

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, …

Asset-Rich And Cash-Poor: Which Older Adults Value Reverse Mortgages?, Joelle H. Fong, Olivia S. Mitchell, Benedict S. K. Koh

Research Collection Lee Kong Chian School Of Business

Home equity represents a substantial share of retirement wealth for many older persons, particularly in Asia where national housing policies have encouraged home-ownership. This paper explored the potential for reverse mortgages to help 'asset-rich and cash-poor' older Singaporeans unlock their home equity while ageing in place. The empirical analysis was based on a nationally representative survey of home-owners age 50+ in the 2018 Singapore Life Panel (N = 6,258). Our analyses showed that the average older home-owner holds some 60 per cent of total net wealth in housing equity, suggestive of high demand potential for reverse mortgage products. Nevertheless, actual …

Economic Forecasting In A Pandemic: Some Evidence From Singapore, Hwee Kwan Chow-Tan, Keen Meng Choy

Research Collection School Of Economics

This paper aims to investigate whether the predictive performance and behaviour of professional forecasters are different during the COVID-19 pandemic as compared with the global financial crisis of 2008 and normal times. To this end, we use a survey of professional forecasters in Singapore collated by the central bank to analyse the forecasting records for GDP growth and CPI inflation for the period 2000Q1–2021Q4. We first examine the point forecasts to document the extent of forecast failure duringthe two crises and explore various explanations for it, such as leader-following and herding behaviour. Then, using percentile-based summary measures of probability distribution …

Improved Marginal Likelihood Estimation Via Power Posteriors And Importance Sampling, Yong Li, Nianling Wang, Jun Yu

Research Collection School Of Economics

Power posteriors have become popular in estimating the marginal likelihood of a Bayesian model. A power posterior is referred to as the posterior distribution that is proportional to the likelihood raised to a power b∈[0,1]. Important power-posterior-based algorithms include thermodynamic integration (TI) of Friel and Pettitt (2008) and steppingstone sampling (SS) of Xie et al. (2011). In this paper, it is shown that the Bernstein–von Mises (BvM) theorem holds for power posteriors under regularity conditions. Due to the BvM theorem, power posteriors, when adjusted by the square root of the auxiliary constant, have the same limit distribution as the original …

Friends Can Help: The Effects Of Relationship In The Chinese Book-Building Process, Ting Luo, Wei Luo, Heng Yue, Lu Zhang

Research Collection School Of Accountancy

Using detailed bidding information in Chinese IPO book-building process, we find that institutional investors who have a close relationship with the underwriter are more likely to participate in bidding and their bidding prices are higher, compared to other institutional investors. We also find that related institutional investors bid higher when the underwriter is more likely to need or receive their support. Further analysis suggests that related institutional investors gain some benefits for their support to the underwriter, including receiving more shares in profitable IPOs, better timing their exit from the IPO in the open market, and receiving more optimistic earnings …
