Similar But Not Quite The Same: Differential Unique Associations Of Trait Fear And Trait Anxiety With Inhibitory Control, Wei Xing Toh, Hwajin Yang Mar 2020

Similar But Not Quite The Same: Differential Unique Associations Of Trait Fear And Trait Anxiety With Inhibitory Control, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

Given the dearth of research regarding the relations of trait fear and trait anxiety to cognitive control processes, we sought to investigate how trait fear and trait anxiety are uniquely related to inhibitory control, which is a crucial component of the regulatory processes that inhibit inappropriate responses that interfere with goal achievement. Given that inhibitory control tasks are often plagued by task-impurity issues, we employed a latent variable approach based on multiple measures of inhibitory control. We found that trait fear and trait anxiety are related but separable constructs that, when their shared variance was controlled for, predicted inhibitory control …

Refusal Bias In Hiv Data From The Demographic And Health Surveys: Evaluation, Critique And Recommendations, Oyelola A. Adegboye, Tomoki Fujii, Denis H. Y. Leung Mar 2020

Refusal Bias In Hiv Data From The Demographic And Health Surveys: Evaluation, Critique And Recommendations, Oyelola A. Adegboye, Tomoki Fujii, Denis H. Y. Leung

Research Collection School Of Economics

Non-response is a commonly encountered problem in many population-based surveys. Broadly speaking, non-response can be due to refusal or failure to contact the sample units. Although both types of non-response may lead to bias, there is much evidence to indicate that it is much easier to reduce the proportion of non-contacts than to do the same with refusals. In this article, we use data collected from a nationally representative survey under the Demographic and Health Surveys program to study non-response due to refusals to HIV testing in Malawi. We review existing estimation methods and propose novel approaches to the estimation …

Tackling Regional Climate Change Impacts And Food Security Issues: A Critical Analysis Across Asean, Pif, And Saarc, Md. Saidul Islam, Edson Kieu Mar 2020

Tackling Regional Climate Change Impacts And Food Security Issues: A Critical Analysis Across Asean, Pif, And Saarc, Md. Saidul Islam, Edson Kieu

Research Collection Lee Kong Chian School Of Business

Climate change and food security issues are multi-faceted and transcend across national boundaries. Therefore, this paper begins with the premise that regional organizations are optimally positioned to address climate change and food security issues while actively engaging global partners to slow down or reverse current trajectories. However, the potential of regional organizations to play a central role in mitigating these vital concerns has not been realized. In this paper, we focus on three regional organizations—the Association of Southeast Asian Nations (ASEAN), the Pacific Islands Forum (PIF), and the South Asian Association for Regional Cooperation (SAARC) and set out to investigate …

Specification Tests For Temporal Heterogeneity In Spatial Panel Data Models With Fixed Effects, Yuhong Xu, Zhenlin Yang Mar 2020

Specification Tests For Temporal Heterogeneity In Spatial Panel Data Models With Fixed Effects, Yuhong Xu, Zhenlin Yang

Research Collection School Of Economics

We propose adjusted quasi score (AQS) tests for testing the existence of temporal heterogeneity in slope and spatial parameters in spatial panel data (SPD) models, allowing for the presence of individual-specific and/or time-specific fixed effects (or in general intercept heterogeneity). The SPD model with spatial lag is treated in detail by first considering the model with individual fixed effects only, and then extending it to the model with both individual and time fixed effects. Two types of AQS tests (naïve and robust) are proposed, and their asymptotic properties are presented. These tests are then fully extended to SPD models with …

Common Power Laws For Cities And Spatial Fractal Structures, Tomoya Mori, Tony E. Smith, Wen-Tai Hsu Mar 2020

Common Power Laws For Cities And Spatial Fractal Structures, Tomoya Mori, Tony E. Smith, Wen-Tai Hsu

Research Collection School Of Economics

City-size distributions are known to be well approximated by power laws across a wide range of countries. But such distributions are also meaningful at other spatial scales, such as within certain regions of a country. Using data from China, France, Germany, India, Japan, and the United States, we first document that large cities are significantly more spaced out than would be expected by chance alone. We next construct spatial hierarchies for countries by first partitioning geographic space using a given number of their largest cities as cell centers and then continuing this partitioning procedure within each cell recursively. We find …

Hybrid Stochastic Local Unit Roots, Offer Lieberman, Peter C. B. Phillips Mar 2020

Hybrid Stochastic Local Unit Roots, Offer Lieberman, Peter C. B. Phillips

Research Collection School Of Economics

Two approaches have dominated formulations designed to capture small departures from unit root autoregressions. The first involves deterministic departures that include local-to-unity (LUR) and mildly (or moderately) integrated (MI) specifications where departures shrink to zero as the sample size n -> infinity. The second approach allows for stochastic departures from unity, leading to stochastic unit root (STUR) specifications. This paper introduces a hybrid local stochastic unit root (LSTUR) specification that has both LUR and STUR components and allows for endogeneity in the time varying coefficient that introduces structural elements to the autoregression. This hybrid model generates trajectories that, upon normalization, …

Random Assignment Of Bundles, Shurojit Chatterji, Peng Liu Mar 2020

Random Assignment Of Bundles, Shurojit Chatterji, Peng Liu

Research Collection School Of Economics

We propose a model studying the random assignments of bundles with no free disposal. The key difference between our model and the one where objects are allocated (see Bogomolnaia and Moulin (2001)) is one of feasibility. The implications of this difference are significant. Firstly, the characterization of sd-efficient random assignments is more complex. Secondly, we are able to identify a preference restriction, called essential monotonicity, under which the random serial dictatorship rule (extended to the setting with bundles) is equivalent to the probabilistic serial rule (extended to the setting with bundles). This equivalence implies the existence of a rule on …

Welfare Consequences Of Access To Health Insurance For Rural Households: Evidence From The New Cooperative Medical Scheme In China, Jessica Ya Sun Mar 2020

Welfare Consequences Of Access To Health Insurance For Rural Households: Evidence From The New Cooperative Medical Scheme In China, Jessica Ya Sun

Research Collection School Of Economics

This study evaluates the welfare benefits of the New Cooperative Medical Scheme (NCMS), the main public health insurance plan for the rural population in China. The findings show that the value of the NCMS to recipients is slightly lower than the government's costs of implementation, ranging from 0.79 to 0.97 per RMB of the resource cost of the NCMS. The estimated moral hazard costs are low compared with the total benefits. It is also estimated that the benefits originating from the NCMS's insurance function only constitute 20% of the total benefits, suggesting a need for higher generosity levels among rural …

Multiple Speed Assessments: Theory, Practice, And Research Evidence, Christoph N. Herde, Filip Lievens Mar 2020

Multiple Speed Assessments: Theory, Practice, And Research Evidence, Christoph N. Herde, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This paper presents Multiple Speed Assessments as an umbrella term to encompass a variety of approaches that include multiple (e.g., 20), short (e.g., 3 min), and often integrated interpersonal simulations to elicit overt behavior in a standardized way across participants. Multiple Speed Assessments can be used to get insight into the behavioral repertoire of a target person in situations sampled from a predefined target domain and their intraindividual variability across these situations. This paper outlines the characteristics and theoretical basis of Multiple Speed Assessments. We also discuss various already existing examples of Multiple Speed Assessments (Objective Structured Clinical Examinations, Multiple …

Time-Series Momentum: Is It There?, Dashan Huang, Jiangyuan Li, Liyao Wang, Guofu Zhou Mar 2020

Time-Series Momentum: Is It There?, Dashan Huang, Jiangyuan Li, Liyao Wang, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

Time-series momentum (TSM) refers to the predictability of the past 12-month return on the next one-month return, and is the focus of several recent influential studies. This paper shows, however, that asset-by-asset time-series regressions reveal little evidence of TSM, both in- and out-of-sample. While the t-statistic in a pooled regression appears large, it is not statistically reliable as it is less than the critical values of parametric and non-parametric bootstraps. From an investment perspective, the TSM strategy is profitable, but its performance is virtually the same as that of a similar strategy that is based on historical sample mean and …

"I Like It, But I Don't Use It": Impact Of Carsharing Business Models On Usage Intentions In The Sharing Economy, Ruediger Hahn, Felix Ostertag, Adrian Lehr, Marion Buettgen, Sabine Benoit Mar 2020

"I Like It, But I Don't Use It": Impact Of Carsharing Business Models On Usage Intentions In The Sharing Economy, Ruediger Hahn, Felix Ostertag, Adrian Lehr, Marion Buettgen, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

Carsharing is often promoted as a potentially environmental-friendly alternative to individual car ownership. However, various carsharing programs have displayed limited success in the past. An initial field study of a new carsharing service is such a story of failure: The introduction of this new service at a medium-sized German university generated unexpectedly low adoption rates so that the service was eventually scaled down and then suspended. Quantitative field study results as well as additional qualitative focus groups reveal that missing compatibility is a key barrier to adoption. Drawing on extant conceptual frameworks of user participation in sharing business models, a …

Estimation Of Fixed Effects Spatial Dynamic Panel Data Models With Small T And Unknown Heteroskedasticity, Liyao Li, Zhenlin Yang Mar 2020

Estimation Of Fixed Effects Spatial Dynamic Panel Data Models With Small T And Unknown Heteroskedasticity, Liyao Li, Zhenlin Yang

Research Collection School Of Economics

We consider the estimation and inference of fixed effects (FE) spatial dynamic panel data (SDPD) models under small T and unknown heteroskedasticity by extending the M-estimation strategy for homoskedastic FE-SDPD model of Yang (2018, Journal of Econometrics). Unbiased estimating equations are obtained by adjusting the conditional quasi-score functions given the initial observations, leading to M-estimators that are free from the initial conditions and robust against unknown cross-sectional heteroskedasticity. Consistency and asymptotic normality of the proposed M-estimator are established. The standard errors are obtained by representing the estimating equations as sums of martingale differences. Monte Carlo results show that the proposed …

Sustainable Cooperation In International Trade: A Quantitative Analysis, Yuan Mei Mar 2020

Sustainable Cooperation In International Trade: A Quantitative Analysis, Yuan Mei

Research Collection School Of Economics

How does the presence of multilateral institutions affect the sustainability of trade-policy cooperation? Do free-trade agreements make multilateral cooperation less sustainable? Will countries be more likely to deviate from negotiated tariffs when more trade liberalization realizes in the future? These questions have been studied in theory literature using models that feature repeated games, but have yet to be quantitatively analyzed. In this paper, I propose a methodology to quantitatively characterize the equilibrium strategies on tariffs of various nations in a widely used repeated-game framework. I then apply this methodology to address these questions from a quantitative perspective. The numerical results …

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy Mar 2020

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy

Research Collection School Of Economics

We use contemporaneous and retrospective panel datasets to examine the household-level relationship between fertility and access to electricity in Bangladesh. We find that access to electricity reduces fertility by about 0.2 children over a period of five years or total fertility rate by about 1.2 in most estimates. This finding is robust with respect to the choice of the estimation method, the choice of sample, and potential presence of endogeneity. The finding also corroborates the theoretical predictions on time use and consumption pattern derived from our model of electrification and fertility. The results also suggest that television is an important …

Examining The Cross-Cultural Validity Of The Positive Affect And Negative Affect Schedule Between An Asian (Singaporean) Sample And A Western (American) Sample, Sean Teck Hao Lee, Andree Hartanto, Jose C. Yong, Brandon Koh, Angela K. Y. Leung Mar 2020

Examining The Cross-Cultural Validity Of The Positive Affect And Negative Affect Schedule Between An Asian (Singaporean) Sample And A Western (American) Sample, Sean Teck Hao Lee, Andree Hartanto, Jose C. Yong, Brandon Koh, Angela K. Y. Leung

Research Collection School of Social Sciences

The positive affect and negative affect schedule (PANAS) is a popular measure of positive (PA) and negative affectivity (NA). Developed and validated in Western contexts, the 20-item scale has been frequently administered on respondents from Asian countries with the assumption of cross-cultural measurement invariance. We examine this assumption via a rigorous multigroup confirmatory factor analysis, which allows us to assess between-group differences in both strength of scale item-to-latent factor relationship (metric invariance test) and mean of each scale item (scalar invariance test), on a large sample of 1,065 respondents recruited from Singapore (Asian sample) and the United States (Western sample). …

Translation Of: Interview With Jacques Derrida: The Western Question Of "Forgiveness" And The Intercultural Relation, Ning Zhang, Steven Burik Mar 2020

Translation Of: Interview With Jacques Derrida: The Western Question Of "Forgiveness" And The Intercultural Relation, Ning Zhang, Steven Burik

Research Collection School of Social Sciences

These two interviews with Jacques Derrida were conducted by Ning Zhang in 1999 and 2000, respectively, in preparation for the publication of his book Writing and Difference in Chinese and his first academic trip to China in 2001. In the first interview, Jacques Derrida tries to clarify the ethical concerns with regard to his deconstructive analysis of Western traditions, through his critical reading of the concept of forgiveness. In this interview he gives us a clearer insight into his ideas about the problem of intercultural exchange, especially concerning questions of translation, translatability, and untranslatability, as central issues of his work. …

Translation Of: Place: Derrida And Nishitani, Rolf Elberfeld, Steven Burik Mar 2020

Translation Of: Place: Derrida And Nishitani, Rolf Elberfeld, Steven Burik

Research Collection School of Social Sciences

In his works Chora [Derrida, Jacques. 1993. Khôra. Paris: Galilée] and “Comment ne pas parler? Denegations” Derrida used the metaphor chora from Plato’s Timaeus (49a and following) to continue his struggle with the metaphysics of presence. In 1926 Nishida, the founder of the Japanese Kyōto School, used the same metaphor to create a new foundation of philosophy. Nishitani, a disciple of Nishida, developed the work of Nishida in close connection to Zen Buddhist experiences. Derrida tries to show the limits of language within the game of language, whereas Nishitani starts from an experience beyond language, but tries to make …

Why Do Businesses Grow Faster In Urban Areas Than In Rural Areas?, Lee, Jungho, Jianhuan Xu Mar 2020

Why Do Businesses Grow Faster In Urban Areas Than In Rural Areas?, Lee, Jungho, Jianhuan Xu

Research Collection School Of Economics

We document that growth of business earnings is mostly observed among young firmsin metro areas. Three explanations are considered: metro areas attract more-productiveentrepreneurs, and reaching the optimal size takes time due to borrowing constraints;metro areas provide better learning opportunities; and high operating costs in metroareas allow only the productive firms to survive. We use a firm-dynamics model with alocation choice to quantify the extent to which the three theories explain the data. Wefind the first two theories largely explain the high growth among metro, young firms. Ourmodel also suggests the distortion in entrepreneurs’ location choice can induce substantialwelfare loss.

Skbi Big 5 Survey 2020 February, Singapore Management University Feb 2020

Skbi Big 5 Survey 2020 February, Singapore Management University

Sim Kee Boon Institute for Financial Economics

On balance, our overall read of the latest multiyear Big5 survey results implies the following economy-at-risk scale (least to most): India, US, Euro Area, Japan and China (i.e., India’s economy might be least at-risk, while China is deemed to be most at-risk). Broadly, survey participants expect the risk assessment to GDP growth to be skewed to the downside in 2020 followed by a more balanced backdrop in 2021. But participants seem to be more divided, with most responses favoring “downside” or/and “balanced” risks, on the 2022 growth environment. The risks to headline inflation in 2020, however, appear to be more …

Economic And Environmental Implications Of Biomass Commercialization In Agricultural Processing, Bin Li, Onur Boyabatli, Buket Avci Feb 2020

Economic And Environmental Implications Of Biomass Commercialization In Agricultural Processing, Bin Li, Onur Boyabatli, Buket Avci

Research Collection Lee Kong Chian School of Business

Motivated by the agricultural industries, this paper studies the economic and environmental implications of biomass commercialization; that is, converting organic waste into a saleable product, from the perspective of a processor that uses a commodity input to produce both a commodity output and biomass. We characterize the economic value of biomass commercializa- tion and examine how input and output spot price uncertainties affect this value. Using a model calibration, we find that lower input spot price variability or higher output spot price variabil- ity or correlation between the two spot prices increases this value for a typical palm oil mill. …

Neural Approximate Dynamic Programming For On-Demand Ride-Pooling, Sanket Shah, Meghna Lowalekar, Pradeep Varakantham Feb 2020

Neural Approximate Dynamic Programming For On-Demand Ride-Pooling, Sanket Shah, Meghna Lowalekar, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

On-demand ride-pooling (e.g., UberPool, LyftLine, GrabShare) has recently become popular because of its ability to lower costs for passengers while simultaneously increasing revenue for drivers and aggregation companies (e.g., Uber). Unlike in Taxi on Demand (ToD) services – where a vehicle is assigned one passenger at a time – in on-demand ride-pooling, each vehicle must simultaneously serve multiple passengers with heterogeneous origin and destination pairs without violating any quality constraints. To ensure near real-time response, existing solutions to the real-time ride-pooling problem are myopic in that they optimise the objective (e.g., maximise the number of passengers served) for the current …

Research Collection School Of Accountancy

This paper is the first to investigate the role of work-life balance in financial analysts’ performance and career advancement. Using a large sample of Glassdoor reviews by financial analysts, we find a significant non-linear relation between work-life balance satisfaction and analyst performance and analyst career advancement. Specifically, when work-life balance satisfaction is relatively low, an increase in work-life balance is associated with better analyst performance and career advancement; however, when perceived work-life balance is already high, a further increase in work-life balance is associated with worse analyst performance and career advancement.
