Interpersonal Dynamics In Assessment Center Exercises: Effects Of Role Player Portrayed Disposition, Tom Oliver, Peter Hausdorf, Filip Lievens, Peter Conlon

Research Collection Lee Kong Chian School Of Business

Although interpersonal interactions are the mainstay of many assessment center exercises, little is known about how these interactions unfold and affect participant behavior and performance. More specifically, participants interact with role players who have been instructed to demonstrate behavior reflecting specific dispositions as part of the exercise. This study focuses on role player portrayed disposition as a potentially important social demand relevant to participant behavior and performance in interpersonal simulations. We integrate interpersonal theory and trait activation theory to formulate hypotheses about the effects of role player portrayed disposition on participant behavior and performance in 184 interpersonal simulations. A significant …

Can Asians Be Creative?, Chua, Roy Y. J., Jerry Zremski

Research Collection Lee Kong Chian School Of Business

A crotchety American named Henry Ford invented a modern, fast and efficient way to manufacture automobiles and a Japanese man named Eiji Toyoda refined and perfected it. A series of innovators across the western world developed the television - and the tech specialists at Sony, Toshiba and a host of other Asian companies found ways to make TVs better, cheaper, faster. And an idiosyncratic Californian named Steve Jobs invented a company that made a smart phone for the masses - and then outsourced the manufacturing to China. If you detect a pattern here, you are not alone. Asia may be …

Bargaining Zone Distortion In Negotiations: The Elusive Power Of Multiple Alternatives, Michael Schaerer, David D. Loschelder, Roderick I. Swaab

Research Collection Lee Kong Chian School Of Business

We challenge the assumption that having multiple alternatives is always better than a single alternative by showing that negotiators who have additional alternatives ironically exhibit downward-biased perceptions of their own and their opponent’s reservation price, make lower demands, and achieve worse outcomes in distributive negotiations. Five studies demonstrate that the apparent benefits of multiple alternatives are elusive because multiple alternatives led to less ambitious first offers (Studies 1–2) and less profitable agreements (Study 3). This distributive disadvantage emerged because negotiators’ perception of the bargaining zone was more distorted when they had additional (less attractive) alternatives than when they only had …

Days To Cover And Stock Returns, Harrison G. Hong, Frank Weikai Li, Sophie X. Ni, Jose A. Scheinkman, Philip Yan

Research Collection Lee Kong Chian School Of Business

A crowded trade emerges when speculators' positions are large relative to the asset's liquidity, making exit difficult. We study this problem of recent regulatory concern by focusing on short-selling. We show that days to cover (DTC), the ratio of short interest to trading volume, measures the costliness of exiting crowded trades. Crowding is an important concern as short-sellers avoid illiquid stocks, which we establish using an instrumental-variables strategy involving staggered stock market decimalization reforms. Arbitrageurs require a premium to enter into such trades as a strategy shorting high DTC stocks and buying low DTC stocks generates a 1.2% monthly return. …

Homogeneity Pursuit In Panel Data Models: Theory And Applications, Wuyi Wang, Peter C. B. Phillips, Liangjun Su

Research Collection School Of Economics

This paper studies estimation of a panel data model with latent structures where individuals can be classified into different groups where slope parameters are homogeneous within the same group but heterogeneous across groups. To identify the unknown group structure of vector parameters, we design an algorithm called Panel-CARDS which is a systematic extension of the CARDS procedure proposed by Ke, Fan, and Wu (2015) in a cross section framework. The extension addresses the problem of comparing vector coefficients in a panel model for homogeneity and introduces a new concept of controlled classification of multidimensional quantities called the segmentation net. We …

Asymptotically Refined Score And Gof Tests For Inverse Gaussian Models, Anthony F. Desmond, Zhenlin Yang

Research Collection School Of Economics

The score test and the GOF test for the inverse Gaussian distribution, in particular the latter, are known to have large size distortion and hence unreliable power when referring to the asymptotic critical values. We show in this paper that with the appropriately bootstrapped critical values, these tests become second-order accurate, with size distortion being essentially eliminated and power more reliable. Two major generalizations of the score test are made: one is to allow the data to be right-censored, and the other is to allow the existence of covariate effects. A data mapping method is introduced for the bootstrap to …

Shrinkage Estimation Of Covariance Matrix For Portfolio Choice With High Frequency Data, Cheng Liu, Ningning Xia, Jun Yu

Research Collection School Of Economics

This paper examines the usefulness of high frequency data in estimating the covariancematrix for portfolio choice when the portfolio size is large. A computationally convenientnonlinear shrinkage estimator for the integrated covariance (ICV) matrix of financial as-sets is developed in two steps. The eigenvectors of the ICV are first constructed from adesigned time variation adjusted realized covariance matrix of noise-free log-returns of rel-atively low frequency data. Then the regularized eigenvalues of the ICV are estimated byquasi-maximum likelihood based on high frequency data. The estimator is always positivedefinite and its inverse is the estimator of the inverse of ICV. It minimizes the …

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips

Research Collection School Of Economics

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are consideredpenalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and …

Semiparametric Single Index Panel Data Models With Interactive Fixed Effects: Theory And Practice, Guohua Feng, Bin Peng, Liangjun Su, Thomas Tao Yang

Research Collection School Of Economics

In this paper, we propose a single-index panel data model with unobserved multiple interactive fixed effects. This model has the advantages of being flexible and of being able to allow for common shocks and their heterogeneous impacts on cross sections, thus making it suitable for the investigation of many economic issues. We derive asymptotic theories for both the case where the link function is integrable and the case where the link function is non-integrable. Our Monte Carlo simulations show that our methodology works well for large N and T cases. In our empirical application, we illustrate our model by analyzing …

Invitation Strategy For Cutting Edge Industries Through Mncs And Global Talents: The Case Of Singapore, Kim Song Tan

Research Collection School Of Economics

Singapore presents an interesting case of how a country achieves dynamic economic development and innovation through the "invitation" strategy of a business hub. Despite being a small city-state with limited domestic market size and no meaningful hinterland or natural resources to speak of, Singapore has managed to transform its economy dramatically over the past 50 years by leveraging the strengths of other economies. Specifically, it has been able to attract (or "invite") various types of productive resources, including foreign capital, foreign technology and foreign workers (both skilled and unskilled) to make up for what it lacks. This has helped Singapore …

Bias Correction And Refined Inferences For Fixed Effects Spatial Panel Data Models, Zhenlin Yang, Jihai Yu, Shew Fan Liu

Research Collection School Of Economics

This paper first presents simple methods for conducting up to third-order bias and variance corrections for the quasi maximum likelihood (QML) estimators of the spatial parameter(s) in the fixed effects spatial panel data (FE-SPD) models. Then, it shows how the bias and variance corrections lead to refined t-ratios for spatial effects and for covariate effects. The implementation of these corrections depends on the proposed bootstrap methods of which validity is established. Monte Carlo results reveal that (i) the QML estimators of the spatial parameters can be quite biased, (ii) a second-order bias correction effectively removes the bias, and (iii) the …

On David Miller On Immigration Control, Chandran Kukathas

Research Collection School of Social Sciences

David Miller offers a liberal realist defence of immigration control grounded in cosmopolitan ideals of self-determination, fairness and integration. But a commitment to liberal values requires a commitment to more open borders than he admits. A part of the problem is that the notion of open borders Miller criticises is under-theorised. A deeper problem is that immigration control itself is inconsistent with important liberal values – notably the values of freedom and equality. This is a concern because it is the freedom and equality not only of immigrants but also of citizens that is threatened by the closing of borders.

Coll-App-Orating With Students: Ibeacons And Ar And Gamification, Oh My!, Jiaxin Low

Research Collection Library

Freshmen at Singapore Management University are required to attend library orientation in person before their first term. Traditional workshops were replaced in 2012 by LibQuest, a problem-based activity which received positive feedback from students.

However, due to increasing sizes of each freshmen cohort, we started considering alternatives which were more scalable and sustainable.

In 2015, we collaborated with a student team from the School of Information Systems on a Proof of Concept: a mobile app that allows on-demand library orientation.

In the app, users are tasked to capture “monsters” scattered throughout the library. The app alerts users if there are …

Housing Policies In Singapore, Phang Sock Yong, Matthias Helble

Research Collection School of Economics

Singapore has developed a unique housing system, with three-quarters of its housing stock built by the Housing & Development Board (HDB) and homeownership financed through Central Provident Fund (CPF) savings. As a result, the country’s homeownership rate of 90% is one of the highest among market economies. At different stages of its economic development, the Government of Singapore was faced with a different set of housing problems. An integrated land–housing supply and financing framework was established in the 1960s to solve the severe housing shortage. By the 1990s, the challenge was that of renewing aging estates and creating a market …

Achieving Economic And Environmental Sustainabilities In Urban Consolidation Center With Bicriteria Auction, Stephanus Daniel Handoko, Hoong Chuin Lau, Shih-Fen Cheng

Research Collection School Of Computing and Information Systems

Consolidation lies at the heart of the last-mile logistics problem. Urban consolidation centers (UCCs) have been set up to facilitate such consolidation all over the world. To the best of our knowledge, most-if not all-of the UCCs operate on volume-based fixed-rate charges. To achieve environmental sustainability while ensuring economic sustainability in urban logistics, we propose, in this paper, a bicriteria auction mechanism for the automated assignment of last-mile delivery orders to transport resources. We formulate and solve the winner determination problem of the auction as a biobjective programming model. We then present a systematic way to generate the Pareto frontier …

Tracking Virality And Susceptibility In Social Media, Tuan Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

In social media, the magnitude of information propagation hinges on the virality and susceptibility of users spreading and receiving the information respectively, as well as the virality of information items. These users' and items' behavioral factors evolve dynamically at the same time interacting with one another. Previous works however measure the factors statically and independently in a restricted case: each user has only a single adoption on each item, and/or users' exposure to items are observable. In this work, we investigate the inter-relationship among the factors and users' multiple adoptions on items to propose both new static and temporal models …

Technology-Mediated Synchronous Virtual Education: An Empirical Study, Xiaofeng Chen, Keng Siau

Research Collection School Of Computing and Information Systems

Many higher education institutions have used Internet technology to develop virtual education for a new generation of college students. In this research, the authors assessed the relative effectiveness of two technology-mediated learning environments for synchronous higher education compared to a traditional face-to-face learning environment. Specifically, they assessed the effects of these three learning environments on interactivity, perceived learning, and satisfaction when different instructional strategies were used. The authors' findings suggest that learning environments interact with instructional strategies to affect the learners' perception of learning and satisfaction. Their findings also support the proposition that the new generation of college students prefer …

A Closer Look At The Hedonics Of Everyday Meaning And Satisfaction, William Tov, Huey Woon Lee

Research Collection School of Social Sciences

Contrasts between eudaimonic well-being and hedonic well-being often compare meaning and happiness. Less work has examined the extent to which meaning and satisfaction can be distinguished. Across five diary studies (N = 923) and a large cross-sectional survey (N = 1471), we examined the affective profile of meaning and satisfaction in everyday life. Using response surface methodology, both judgments were modeled as a joint function of positive (PA) and negative (NA) affect. Affective discrepancy (preponderance of PA over NA) was more strongly associated with satisfaction than meaning. In general, meaning correlated less with affect than satisfaction, but the …

Conceptual Representation Changes In Indonesian-English Bilinguals, Andree Hartanto, Lidia Suarez

Research Collection School of Social Sciences

This study investigated conceptual representations changes in bilinguals. Participants were Indonesian-English bilinguals (dominant in Indonesian, with different levels of English proficiency) and a control group composed of English-dominant bilinguals. All completed a gender decision task, in which participants decided whether English words referred to a male or female person or animal. In order to explore conceptual representations, we divided the words into gender-specific and gender-ambiguous words. Gender-specific words were words in which conceptual representations contained gender as a defining feature, in both English and Indonesian (e.g., uncle). In contrast, gender-ambiguous words were words in which gender was a defining feature …

Mimicking Religion As Coping Strategy: The Emergence Of The Bell-Curve God In Singapore, Lily Kong

Are European Union Sanctions “Targeted”?, Clara Portela

Research Collection School of Social Sciences

The emergence of targeted sanctions in the mid-1990s was due to the humanitarian impact of embargoes, which were deemed unacceptable and compelled senders to shift to measures designed to affect only wrongdoers. Twenty years on, the present paper considers the extent to which autonomous sanctions are designed to affect those individuals and elites responsible for the behaviour the EU aims to condemn. How faithful has the EU remained to this concept in its sanctions policy? The enquiry scrutinizes diverse practices in three established sanctions strands of the EU, development aid suspensions, Common Foreign and Security Policy (CFSP) sanctions and Generalised …

Cultural Variability In The Link Between Environmental Concern And Support For Environmental Action, Kimin Eom, Heejung S. Kim, David K. Sherman, Keiko Ishii

Research Collection School of Social Sciences

Research on sustainability behaviors has been based on the assumption that increasing personal concerns about the environment will increase proenvironmental action. We tested whether this assumption is more applicable to individualistic cultures than to collectivistic cultures. In Study 1, we compared 47 countries (N = 57,268) and found that they varied considerably in the degree to which environmental concern predicted support for proenvironmental action. National-level individualism explained the between-nation variability above and beyond the effects of other cultural values and independently of person-level individualism. In Study 2, we compared individualistic and collectivistic nations (United States vs. Japan; N = 251) …
