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 …

High Sex Ratios And Household Portfolio Choice In China, Wenchao Li, Changcheng Song, Shu Xu, Junjian Yi

Research Collection Lee Kong Chian School Of Business

This paper studies how high sex ratios (more men than women) affect household portfolio choice. Using data from a nationally representative Chinese household finance survey, we find that a 1 standard deviation increase in the sex ratio would raise the stock market participation rate by 2.9 percentage points or 52.2 percent for families with a son relative to families with a daughter. Our estimates imply that rising sex ratios explain around 10 percent of the significant growth in China’s stock market size in recent decades.

Fit To Be Good: Physical Fitness Is Negatively Associated With Deviance, Kenneth Tai, Yuchuan Liu, Marko Pitesa, Sandy Lim, Yew Kwan Tong, Richards Arvey

Research Collection Lee Kong Chian School Of Business

While modern organizations generate economic value, they also produce negative externalities in terms of human physical fitness, such that workers globally are becoming physically unfit. In the current research, we focus on a significant but overlooked indirect cost that lack of physical fitness entails—deviance. In contrast to early (and methodologically limited) research in criminology, which suggests that physically fit people are more likely to behave in a deviant manner, we draw on self-control theory to suggest the opposite: that physically fit people are less likely to engage in deviance. In Study 1, concurrent as well as time-lagged analyses of a …

Correlation-Robust Auction Design, Wei He, Jiangtao Li

Research Collection School Of Economics

We study the design of auctions when the auctioneer has limited statistical information about the joint distribution of the bidders' valuations. More specifically, we consider an auctioneer who has an estimate of the marginal distribution of a generic bidder's valuation but does not have reliable information about the correlation structure. We analyze the performance of mechanisms in terms of the revenue guarantee, that is, the greatest lower bound of revenue across all joint distributions that are consistent with the marginals. A simple auction format, the second-price auction with no reserve price, is shown to be asymptotically optimal, as the number …

Toward Engaged Scholarship: Knowledge Inclusivity And Collaborative Collection Development Between Academic Libraries And Archives And Local Public Communities, Amanda Y. Makula, Laura S. Turner

Copley Library: Faculty Scholarship

In Open and Equitable Scholarly Communications, ACRL calls for more diverse and inclusive collection development (CD) by academic libraries and archives. Meanwhile, higher education is increasingly committing to community-engaged scholarship. This study investigated the extent to which academic libraries and archives are collecting, curating, and/or preserving knowledge produced by their local public communities. Researchers administered an electronic survey to relevant listservs and conducted follow-up interviews to develop a case study of one library’s efforts. Ninety of the initial 118 survey respondents (76%) indicated that their academic library intentionally collects, curates, and/or preserves materials created or owned by the local …

Mindfulness Attenuates Both Emotional And Behavioral Reactions Following Psychological Contract Breach: A Two-Stage Moderated Mediation Model, Samah Shaffakat, Lilian Otaye-Ebede, Jochen Reb, Rajesh Chandwani, Pisitta Vongswasdi

Research Collection Lee Kong Chian School Of Business

Breach of the psychological contract between organization and employee often evokes employee hostility, which in turn can instigate deviant behaviors. We examine whether employee mindfulness attenuates these reactions to psychological contract breach. Specifically, we develop and test a two-stage moderated mediation model in which employee mindfulness moderates the mediational path from psychological contract breach via hostility to deviance by attenuating both emotional and behavioral reactions. Findings across four studies (with 872 employee participants) both measuring and manipulating breach and mindfulness demonstrate substantial support for the proposed model. Further analyses including alternative moderators, mediators, and dependent variables provide evidence for discriminatory …

Assessing Gender Parity In Intrahousehold Allocation Of Educational Resources: Evidence From Bangladesh, Sijia Xu, Abu S. Shonchoy, Tomoki Fujii

Research Collection School Of Economics

Gender parity in education—an important global development goal—has been primarily measured through school enrollment, and the gender parity in education quality has received limited attention until recently. We address this issue by highlighting the intrahousehold allocation of education expenditure. We extend the hurdle model into a three-part model to enable decomposition of households’ education decisions into enrollment, total education expenditure, and share of the total education expenditure on the core component, or items relating to the quality of education such as private tutoring. We apply this model to four rounds of nationally representative household surveys from Bangladesh, a country that …

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 …

Occupation Density Estimation For Noisy High-Frequency Data, Congshan Zhang, Jia Li, Tim Bollerslev

Research Collection School Of Economics

This paper studies the nonparametric estimation of occupation densities for semimartingale processes observed with noise. As leading examples we consider the stochastic volatility of a latent efficient price process, the volatility of the latent noise that separates the efficient price from the actually observed price, and nonlinear transformations of these processes. Our estimation methods are decidedly nonparametric and consist of two steps: the estimation of the spot price and noise volatility processes based on pre-averaging techniques and in-fill asymptotic arguments, followed by a kernel-type estimation of the occupation densities. Our spot volatility estimates attain the optimal rate of convergence, and …

Conditional Superior Predictive Ability, Jia Li, Zhipeng Liao, Rogier Quaedvlieg

Research Collection School Of Economics

This article proposes a test for the conditional superior predictive ability (CSPA) of a family of forecasting methods with respect to a benchmark. The test is functional in nature: under the null hypothesis, the benchmark’s conditional expected loss is no more than those of the competitors, uniformly across all conditioning states. By inverting the CSPA tests for a set of benchmarks, we obtain confidence sets for the uniformly most superior method. The econometric inference pertains to testing conditional moment inequalities for time series data with general serial dependence, and we justify its asymptotic validity using a uniform non-parametric inference method …

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 …

Bank, Stock Market Efficiency And Economic Growth: Panel Data Evidence From Asean-5, Asia-5 And Oecd-7 Countries, Swee Liang Tan

Research Collection School Of Economics

This paper estimates bank and stock market efficiency associations with real per capita GDP growth by examining panel-data across three different regions using Beck-Katz Panel-Corrected Standard Errors (PCSE) regression. It allows heteroskedastic and/or contemporaneously correlated disturbances across panels, with to specify a common first-order autocorrelation within the panel. The results suggest efficiency effects on growth is not unambiguous. The results suggest a threshold beyond which increase in bank overhead cost hurts economic growth, for developing countries. Likewise, there is a threshold beyond which increase in stock market turnover ratio hurts economic growth, for developed countries. One policy implication of the …

Congestion Costs And Scheduling Preferences Of Car Commuters In California: Estimates Using Big Data, Jinwon Kim, Jucheol Moon

Mineta Transportation Institute

On average, California car commuters waste 4–5 minutes per morning commute due to congestion. Multiplied across all California car commuters, those few minutes entail a yearly total of approximately 2.3 billion hours of time wasted, costing 6 billion dollars. The objective of this study is to quantify congestion costs and determine how commuters adapt to the level of congestion they face (i.e., commuters’ scheduling utility functions). To that end, this research developed a model of trip scheduling under congestion to construct California commuters’ travel-time profiles, i.e., the menu of travel times that each individual would likely face according to alternate …

The Effects Of Physician Retirement On Patient Outcomes: Anticipation And Disruption, Xuan Zhang

Research Collection School Of Economics

The physician retirement rate in the United States is increasing as the population ages. I use an event study model allowing for anticipation to evaluate the effects of primary care physician (PCP) retirement on elderly adults’ health care utilization and quality of care. I find that, despite moderate anticipatory effects, PCP retirement results in an approximately $572 increase in total Medicare costs per beneficiary in the first 1.5 years post-retirement and an over 10% increase in detection of new chronic conditions. Heterogeneity analyses show that the increase in costs is disproportionately driven by the retirement of solo practitioners; Medicare beneficiaries …

Declining Discount Rates In Singapore's Market For Privately Developed Apartments, Eric Fesselmeyer, Haoming Liu, Alberto Salvo

Research Collection College of Integrative Studies

Singapore's market for new privately developed apartments exhibits wide quasi-experimental variation in ownership tenure. We develop an empirical model in which prices are decomposed into the utility of housing services and a factor that shifts with asset tenure and the discount rate schedule, which we discipline to vary smoothly over time. We estimate discount rates that decline over time and, to accommodate the observed price differences, fall to 0.5-1.5% p.a. by year 400. The finding that households making sizable transactions do not entirely discount benefits accruing centuries from today is relevant, with the appropriate risk adjustment, for evaluating climate-change investments.

Technical Report: Reviewing The Relationships Between Urban Morphological Variables And Outdoor Thermal Comfort (Otc) To Assess Comfort Implication Of Densification For Singapore, Shreya Banerjee, Ngai Yan Ching, Sin Kang Yik

Research Collection College of Integrative Studies

Majority thermal comfort studies focus on exploring the relationships between subjective parameters such as personal, physiological, psychological, and behavioral attributes and how they shape Outdoor Thermal Comfort (OTC). Although some attempts have been made to analyze the impact of urban morphological variables, but few have explored the effect of urban densification on OTC. Assessing the impact of density attributes is especially important for highly dense cities such as Singapore. Keeping this in consideration, ths study aims to provide a review-based analysis connecting OTC and various density related morphological variables. Firstly, this report analyses existing literature to provide snapshots on various …

Optimizing Multimodal Transportation Access To Support Commuting Among Low-Income Transit Riders With Social Distancing, Shailesh Chandra, Vivek Mishra

Mineta Transportation Institute

During the COVID-19 pandemic, LA Metro has encouraged social distancing among passengers—especially at stations of high-demand routes—and has increased fixed-route transit (FRT) services. However, potential impacts of social distancing on the performance of FRT services remain mostly unknown. This research evaluates the accessibility of FRT buses with social distancing using the ridership data collected on four FRT routes: 105, 108, 111, and 115 of the LA Metro's A Line stations located in low-income neighborhoods. This research shows that social distancing of six feet can impact FRT's accessibility to destination stations, and maximum accessibility is achieved only for a certain number …

A Posterior-Based Wald-Type Statistic For Hypothesis Testing, Yong Li, Xiaobin Liu, Tao Zeng, Jun Yu

Research Collection School Of Economics

A new Wald-type statistic is proposed for hypothesis testing based on Bayesian posterior distributions under the correct model specification. The new statistic can be explained as a posterior version of the Wald statistic and has several nice properties. First, it is well-defined under improper prior distributions. Second, it avoids Jeffreys–Lindley–Bartlett’s paradox. Third, under the null hypothesis and repeated sampling, it follows a χ2" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; display: inline-block; line-height: normal; font-size: 16.2px; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;">χ2 …

Examining The Effects Of Precision Scheduled Railroading On Intercity Passenger And High-Speed Rail Service, John G. Green, Francis J. Miller

Mineta Transportation Institute

More than just scheduling terminal-to-terminal trips for trains, “Precision Scheduled Railroading” (PSR) creates entire point-to-point trip plans for individual railroad shipments. Since precision execution was first put into practice, the benefits to shipment arrival reliability and to freight railroads’ profitability have been demonstrated by its use in several Class One freight railroads. However, the effects of the PSR operating strategy on passenger railway operations in shared freight/passenger corridors has not been studied in detail. This research examines the effects of PSR railroad operations on passenger railways, including measuring “Host Railroad Minutes of Delay per 10,000 Train-Miles” and “On-Time Performance” of …

Examining The Effects Of A Bike And E-Bike Lending Program On Commuting Behavior, Dillon T. Fitch, Zeyu Gao, Lucy Noble, Terry Mac

Mineta Transportation Institute

In 2015, Google added a new transportation demand management (TDM) program to increase bike commuting to their two main campuses in Mountain View and Sunnyvale, California. An initial survey of employees indicated that bike ownership and worry about maintenance were primary bicycling barriers. With this information, Google began a program that loaned high-quality electric-assisted and conventional bicycles for a period of six months at no cost to interested employees. This research evaluates the effectiveness of the program at changing travel behavior to the corporate campuses by using self-reported and smartphone-integrated travel data. The lending program at Google represents one of, …

Electronic Theses and Dissertations

In this quantitative secondary analysis, the purpose was to examine the nature of disruptive physician behavior (DPB) from the support staff and patient perspectives. Healthcare staffing shortages existed prior to the global pandemic and have increased, creating importance for employee retention and recruitment. I wanted to understand the impact of physician behavior on staff turnover rates in a private oncology practice, its effect on patient satisfaction rates, and to compare these rates of physicians that display DPB with physicians that do not display this behavior in a private hematology oncology community outpatient setting in the Southwest United States. To answer …

The Impact Of Ride-Hail Surge Factors On Taxi Bookings, Sumit Agarwal, Ben Charoenwong, Shih-Fen Cheng, Jussi Keppo

Research Collection School Of Computing and Information Systems

We study the role of ride-hailing surge factors on the allocative efficiency of taxis by combining a reduced-form estimation with structural analyses using machine-learning-based demand predictions. Where other research study the effect of entry on incumbent taxis, we use higher frequency granular data to study how location-time-specific surge factors affect taxi bookings to bound the effect of customer decisions while accounting for various confounding variables. We find that even in a unique market like Singapore, where incumbent taxi companies have app-based booking systems similar to those from ride-hailing companies like Uber, the estimated upper bound on the cross-platform substitution between …

Staff Matters: Is Our Practice Required To Mandate Employee Vaccination For Covid-19?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This Staff Matters Column addresses the confusion surrounding COVID-19 vaccination mandates for private dental practices. Following the U.S. Supreme Court's decision, the Centers for Medicare and Medicaid Services (CMS) vaccine mandate was upheld. However, the CMS rule, clarified through FAQs, applies to specific health care facilities accepting Medicare or Medicaid funding and does not include private dental practices. The article navigates the nuances of the CMS rule, emphasizing its impact on certain health care settings rather than private dental practices, offering clarity on vaccination requirements for dental professionals.

Does Anxiety Moderate The Relationship Between Adhd Inattention Symptoms And Cognitive Flow States?, Anna S. Hall, Dorthie Cross

Psychophysiological Predictors Of Change In Emotion Dysregulation 6 Months After Traumatic Injury, Jacklynn M. Fitzgerald, Sydney Clare Timmer-Murillo, Claire Sheeran, Hailey Begg, Morgan Christoph, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Emotional dysregulation that occurs after trauma conveys risk for multiple disorders, including posttraumatic stress disorder, depression, and anxiety. Psychophysiological data (e.g., skin conductance level [SCL]) may be a useful biomarker for quantifying emotion dysregulation given that autonomic nervous system (ANS)-mediated arousal may underlie this feature. In this longitudinal study, we tested whether SCL collected following a single-incident traumatic injury could predict changes in emotion dysregulation over 6 months. Sixty-six adults were recruited from the emergency department; SCL was quantified during an active trauma narrative, in which participants re-told their traumatic event to a research staff member, as well as a …
