Interviewers' Sensitivity To Impression Management Tactics In Structured Interviews, Filip Lievens, Helga Peeters Jan 2008

Interviewers' Sensitivity To Impression Management Tactics In Structured Interviews, Filip Lievens, Helga Peeters

Research Collection Lee Kong Chian School Of Business

This study examines interviewers' sensitivity to impression management in structured interviews by determining the relative importance that interviewers attach to ( verbal and nonverbal) impression management as compared to the relative importance that they attach to predetermined competencies. Two samples of interviewers ( 55 Master I/O psychology students and 18 professional interviewers) watched and evaluated videotaped interviewees who were instructed to put their best foot forward. Results of relative weight analyses showed that the importance of verbal and nonverbal impression management tactics was relatively small as compared to the importance attached to job-related competencies. The type of interview format had …

Personnel Selection, Paul R. Sackett, Filip Lievens Jan 2008

Personnel Selection, Paul R. Sackett, Filip Lievens

Research Collection Lee Kong Chian School Of Business

We review developments in personnel selection since the previous review by Hough & Oswald (2000) in the Annual Review of Psycholog. We organize the review around a taxonomic structure of possible bases for improved selection, which includes (a) better understanding of the criterion domain and criterion measurement, (b) improved measurement of existing predictor methods or constructs, (c) identification and measurement of new predictor methods or constructs, (d) improved identification of features that moderate or mediate predictor-criterion relationships, (e) clearer understanding of the relationship between predictors or between predictors and criteria (e.g., via meta-analytic synthesis), (f) identification and prediction of new …

The Role Of The Board And Its Interaction With The Successor's Human Capital In The Asian Family Enterprise, Soo-Hoon Lee, Phillip H. Phan, Toru Yoshikawa Jan 2008

The Role Of The Board And Its Interaction With The Successor's Human Capital In The Asian Family Enterprise, Soo-Hoon Lee, Phillip H. Phan, Toru Yoshikawa

Research Collection Lee Kong Chian School Of Business

This study examined the human and social capital factors associated with higher post-succession firm performance in family enterprises in Singapore. We also investigated the moderating influence of the board of directors in terms of its service role as stewards of the enterprise. We found that a successor's industry experience and diversity of network ties were positively associated with firm performance and boards that focused their role as advisors to the successor enhanced post-succession firm performance.

Implications Of Transaction Costs For The Post-Earnings-Announcement Drift, Jeffrey Ng, Rodrigo Verdi, Tjomme Rusticus Jan 2008

Implications Of Transaction Costs For The Post-Earnings-Announcement Drift, Jeffrey Ng, Rodrigo Verdi, Tjomme Rusticus

Research Collection School Of Accountancy

This paper examines the effect of transaction costs on the post–earnings announcement drift (PEAD). Using standard market microstructure features we show that transaction costs constrain the informed trades that are necessary to incorporate earnings information into price. This implies weaker return responses at the time of the earnings announcement and higher subsequent returns drift for firms with higher transaction costs. Consistent with this prediction, we find that earnings response coefficients are lower for firms with higher transaction costs. Using portfolio analyses, we find that the profits of implementing the PEAD trading strategy are significantly reduced by transaction costs. In addition, …

The Framing And Evaluation Of Multiple Hypotheses, Theodore J. Mock, Arnold Wright, Rajendra P. Srivastava, Hai Lu Jan 2008

The Framing And Evaluation Of Multiple Hypotheses, Theodore J. Mock, Arnold Wright, Rajendra P. Srivastava, Hai Lu

Research Collection School Of Accountancy

This study provides exploratory evidence on auditors’ framing and evaluation of hypotheses, identifies implications for improving audit decision-making and facilitates the interpretation of prior research. Prior studies usually assume hypotheses to be framed as mutually exclusive and exhaustive. However, both verbal protocol evidence and probability assessments reveal that in a realistic case most auditors frame the hypotheses as a non-mutually exclusive and exhaustive set of causes. Further, auditor probability assessments tend to reflect multiple causes. Finally, exploratory analyses indicate auditors have difficulty in updating assessments consistent with the perceived interrelationships between hypotheses.

Multi-Echelon Repairable Item Inventory System With Limited Repair Capacity Under Nonstationary Demands, Hoong Chuin Lau, Huawei Song Jan 2008

Multi-Echelon Repairable Item Inventory System With Limited Repair Capacity Under Nonstationary Demands, Hoong Chuin Lau, Huawei Song

Research Collection School Of Computing and Information Systems

Classical multi-echelon repairable item inventory models are based either on steady-state analysis or infinite repair capacity, which may not work well in situations when the demand is nonstationary, or repair capacity is limited. In this paper, we propose an analytical model for evaluating system performance that works well under limited repair capacity and nonstationary demands. Following the METRIC methodology, we then develop an optimisation algorithm to solve the corrective maintenance problem in military logistics. Experimental results show that our approach yields good solutions efficiently. This work has also resulted in a software that has been field-tested by a military organisation.

Enhancing Recursive Supervised Learning Using Clustering And Combinatorial Optimization (Rsl-Cc), Kiruthika Ramanathan, Sheng Uei Guan Jan 2008

Enhancing Recursive Supervised Learning Using Clustering And Combinatorial Optimization (Rsl-Cc), Kiruthika Ramanathan, Sheng Uei Guan

Research Collection School Of Computing and Information Systems

The use of a team of weak learners to learn a dataset has been shown better than the use of one single strong learner. In fact, the idea is so successful that boosting, an algorithm combining several weak learners for supervised learning, has been considered to be one of the best off-the-shelf classifiers. However, some problems still remain, including determining the optimal number of weak learners and the overfitting of data. In an earlier work, we developed the RPHP algorithm which solves both these problems by using a combination of genetic algorithm, weak learner and pattern distributor. In this paper, …

Flirting With A Flourish, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

Sophistication is a French invention. The French are masters when it comes to nurturing, and more importantly, selling sophistication. Think of some expensive (and therefore classy) brands. Chances are that more than half of the ones that spring to mind would be French. And the other half would be distinctly French-sounding wannabes.

A Growth-Theoretic Empirical Analysis Of Simultaneity In Cross-National E-Commerce Development, Shu-Chun Ho, Robert J. Kauffman, Ting-Peng Liang Jan 2008

A Growth-Theoretic Empirical Analysis Of Simultaneity In Cross-National E-Commerce Development, Shu-Chun Ho, Robert J. Kauffman, Ting-Peng Liang

Research Collection School Of Computing and Information Systems

The emergence of information and communication technologies infrastructure has transformed the global economy. The development of information technology infrastructure is limited to some developed countries though. This research explores the role of information technology infrastructure in B2C e-commerce growth at the country-level from the perspective of growth theory in economics. We propose a hybrid exogenous and endogenous growth model to explain e-commerce growth. We estimate a panel data model that incorporates the direct effects of e-commerce infrastructure and other key explanatory variables. We further specify a simultaneous effects model that permits the analysis of reverse causality in the association between …

Face Annotation Using Transductive Kernel Fisher Discriminant, Jianke Zhu, Steven C. H. Hoi, Michael R. Lyu Jan 2008

Face Annotation Using Transductive Kernel Fisher Discriminant, Jianke Zhu, Steven C. H. Hoi, Michael R. Lyu

Research Collection School Of Computing and Information Systems

Face annotation in images and videos enjoys many potential applications in multimedia information retrieval. Face annotation usually requires many training data labeled by hand in order to build effective classifiers. This is particularly challenging when annotating faces on large-scale collections of media data, in which huge labeling efforts would be very expensive. As a result, traditional supervised face annotation methods often suffer from insufficient training data. To attack this challenge, in this paper, we propose a novel Transductive Kernel Fisher Discriminant (TKFD) scheme for face annotation, which outperforms traditional supervised annotation methods with few training data. The main idea of …

Probabilistic Sales Forecasting For Small And Medium-Size Business Operations, Randall E. Duran Jan 2008

Probabilistic Sales Forecasting For Small And Medium-Size Business Operations, Randall E. Duran

Research Collection School Of Computing and Information Systems

One of the most important aspects of operating a business is the forecasting of sales and allocation of resources to fulfill sales. Sales assessments are usually based on mental models that are not well defined, may be biased, and are difficult to refine and improve over time. Defining sales forecasting models for small- and medium-size business operations is especially difficult when the number of sales events is small but the revenue per sales event is large. This chapter reviews the challenges of sales forecasting in this environment and describes how incomplete and potentially suspect information can be used to produce …

A Union Of Gender Equality And Pragmatic Patriarchy: International Marriages And Citizenship Laws In Singapore, Eugene K. B. Tan Jan 2008

A Union Of Gender Equality And Pragmatic Patriarchy: International Marriages And Citizenship Laws In Singapore, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

As a patriarchal society, government policies, societal norms and government regulations in Singapore mirror that normative ideal. Citizenship status and rights along gender lines, manifested in the legal recognition of children of international marriages, reflected this reality for much of Singapore's independence. However, the onslaught of globalization, the rise in international marriages, disconcerting declining birth rates, and an acceptance of 'foreign talent' have given the economic imperative and demographic impulse to grant citizenship (by descent) to a person born outside Singapore whose father or mother is a citizen of Singapore, by birth, registration or descent. Previously, such a person would …

Anarcho-Multiculturalism: The Pure Theory Of Liberalism, Chandran Kukathas

Research Collection School of Social Sciences

Most modern states today are, at least to some degree, culturally diverse.Trade, tourism, international dialogue among scholars, scientists, and artists,and the movement of skilled labor—as well as migration—have ensured thatfew countries do not contain within them significant numbers of people fromalien cultures. The one cultural minority found almost everywhere is the international frequent flyer. Many societies today are multicultural because theyare open to a diversity of peoples who come and go and, sometimes, stay.

Harmful Help: The Costs Of Backing Up Behavior In Teams, Christopher M. Barnes, J. R. Hollenbeck, David Turley Wagner, D. S. Derue, J. D. Nahrgang, K. M. Schwind Jan 2008

Harmful Help: The Costs Of Backing Up Behavior In Teams, Christopher M. Barnes, J. R. Hollenbeck, David Turley Wagner, D. S. Derue, J. D. Nahrgang, K. M. Schwind

Research Collection Lee Kong Chian School Of Business

Prior research on backing-up behavior has indicated that it is beneficial to teams (C. O. L. H. Porter, 2005; C. O. L. H. Porter et al., 2003). This literature has focused on how backing-up behavior aids backup recipients in tasks in which workload is unevenly distributed among team members. The authors of the present study examined different contexts of workload distribution and found that, in addition to the initial benefits to backup recipients, there are initial and subsequent costs. Backing-up behavior leads backup providers to neglect their own taskwork, especially when workload is evenly distributed. Team members who receive high …

The Effect Of Rivals When Firms Emerge From Bankruptcy, Gary L. Caton, Jeffrey Donaldson, Jeremy Goh Jan 2008

The Effect Of Rivals When Firms Emerge From Bankruptcy, Gary L. Caton, Jeffrey Donaldson, Jeremy Goh

Research Collection Lee Kong Chian School Of Business

Studies on the announcement effects of bankruptcy filings have found that when a firm files for Chapter 11 bankruptcy protection its shareholders suffer significant losses. A recent paper extends these findings by investigating the announcement effect on rival companies, while another examines the equity performance of firms emerging from bankruptcy. We combine these two lines of inquiry by examining the effect on rivals when a firm emerges from the protection of Chapter 11. We find both significant negative stock market returns and significant negative revisions in analysts’ earnings forecasts for rivals of successfully reorganized companies.

Birth Spacing Effect On Children's Attainments: Indentification Using Instrument Variables, Jing Xie Jan 2008

Birth Spacing Effect On Children's Attainments: Indentification Using Instrument Variables, Jing Xie

Dissertations and Theses Collection (Open Access)

In this study, I address the relationship between an often overlooked dimension of family structure--the spacing between children's births--and the degree of children's attainments such as Mathematics, Reading Cognition and Reading Comprehension. Comparing to the results of OLS estimation, 2SLS Estimation using Twin and Catholic as Instrument Variables shows less significant effects on children's attainments. Hausman Test shows that OLS estimators are not consistent with 2SLS estimators, which means there is endogenous problem in OLS estimation. As the result in 2SLS shows the different spacing effects in different spacing groups, it is possible to use nonlinear estimation (quadratic form of …

Test For Infinite Variance In Stock Returns, Xian Ning Yan Jan 2008

Test For Infinite Variance In Stock Returns, Xian Ning Yan

Dissertations and Theses Collection (Open Access)

The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory. We compare the performances of the adaptive Hill's estimator and the Smith's estimator for the tail index using Monte Carlo simulations for both i.i.d data and dependent data. The simulation results show that the Hill's estimator with adaptive data-based truncation number performs better in both cases. It has not only smaller bias but also smaller MSE when the true tail index …

The Cross-Section Of Stock Return And Volatility, Hongchao Han Jan 2008

The Cross-Section Of Stock Return And Volatility, Hongchao Han

Dissertations and Theses Collection (Open Access)

There has been increasing research on the cross-sectional relation between stock return and volatility. Conclusions are, however, mixed, partially because volatility or variance is modeled or parameterized in various ways. This paper, by using the Jiang and Tian (2005)'s model-free method, estimates daily option implied volatility for all US individual stocks from 1996:01 to 2006:04, and then employs this information to extract monthly volatilities and their idiosyncratic parts for cross-sectional regression analyses. We follow the Fama and French (1992) cross-sectional regression procedure and show that each of the 4 monthly measures of change of total volatility, total volatility, expected idiosyncratic …

The Impact Of Credit Watch And Bond Rating Changes On Abnormal Stock Returns For Non-Usa Domiciled Corporations, Benjamin Boon Ching Ee Jan 2008

The Impact Of Credit Watch And Bond Rating Changes On Abnormal Stock Returns For Non-Usa Domiciled Corporations, Benjamin Boon Ching Ee

Dissertations and Theses Collection (Open Access)

In this paper, we investigate whether credit watches and bond rating changes issued by Moodys' and S&P Credit Rating Agencies provide significant new information to investors for Non-USA domiciled corporations. We also examine whether the stock related cumulative abnormal return (CAR) differs according to the classification of the country of domicile (emerging or developed) of the corporation, and varies by state of the local stock market during the time of the rating event.
We find that on average, negative credit watches as well as long term rating downgrades result in significant stock related CAR for Non-USA domiciled 4 corporations. However, …

Rational And Boundedly Rational Behavior In Sender-Receiver Games, Massimiliano Landi, Domenico Colucci Jan 2008

Rational And Boundedly Rational Behavior In Sender-Receiver Games, Massimiliano Landi, Domenico Colucci

Research Collection School Of Economics

The authors investigate the strategic rationale behind the message sent by Osama bin Laden on the eve of the 2004 U.S. Presidential elections. They model this situation as a signaling game in which a population of receivers takes a binary choice, the outcome is decided by majority rule, sender and receivers have conflicting interests, and there is uncertainty about both players’ degree of rationality. They characterize the structure of the sequential equilibria of the game as a function of the parameters governing the uncertainty and find that in all pure strategy equilibria, the outcome most preferred by the rational sender …

Target Saving In An Overlapping Generations Model, Ashok S. Guha, Brishti Guha Jan 2008

Target Saving In An Overlapping Generations Model, Ashok S. Guha, Brishti Guha

Research Collection School Of Economics

We examine a model in which the utility function has been engineered so that it is optimal for consumers to aim for a fixed target level of retirement resources. In this case consumption displays excess sensitivity to current income as well as perfect old age insurance. In an overlapping generations model, this leads naturally to multiple and unstable equilibria. Under static expectations, it also leads to a well-defined dynamics, including possible historical traps, implosions involving ever-diminishing capital stock and ever-increasing interest rates, and the feasibility of optimal one-time interventions.

Two-Sample Estimation Of Poverty Rates For Disabled People: An Application To Tanzania, Tomoki Fujii Jan 2008

Two-Sample Estimation Of Poverty Rates For Disabled People: An Application To Tanzania, Tomoki Fujii

Research Collection School Of Economics

Estimating poverty measures for disabled people in developing countries is di cult, partly because relevant data are not available. We develop two methods to estimate poverty by the disability status of the household head. We extend the small-area estimation proposed by Elbers, Lanjouw and Lanjouw (2002, 2003) so that we can run a regression on head's disability status even when such information is unavailable in the survey. We do so by aggregation and by moment adjusted two sample instrumental variable estimation. Our results from Tanzania show that both methods work well, and that disability is indeed associated with poverty.

Education And Trade, Pao Li Chang, Fali Huang Jan 2008

Education And Trade, Pao Li Chang, Fali Huang

Research Collection School Of Economics

This paper examines the inherent link between a countryís education system and its comparative advantage in trade. It suggests that di§erences in education systems across countries are probably a stable equilibrium result that is compatible with and reinforced by trade patterns. In equilibrium, two distinct types of countries emerge, one that exports creativity-intensive products and has an education system encouraging diversity (as illustrated by the US), and the other one that exports high-quality manufactured products and has an education system promoting homogeneity in student quality (as illustrated by Japan). Our Öndings present a novel explanation for the coexistence of low …

Optimal Bandwidth Selection In Heteroskedasticity-Autocorrelation Robust Testing, Yixiao Sun, Peter C. B. Phillips, Sainan Jin Jan 2008

Optimal Bandwidth Selection In Heteroskedasticity-Autocorrelation Robust Testing, Yixiao Sun, Peter C. B. Phillips, Sainan Jin

Research Collection School Of Economics

This paper considers studentized tests in time series regressions with nonparametrically autocorrelated errors. The studentization is based on robust standard errors with truncation lag M = bT for some constant b ∈ (0, 1] and sample size T. It is shown that the nonstandard fixed-b limit distributions of such nonparametrically studentized tests provide more accurate approximations to the finite sample distributions than the standard small-b limit distribution. We further show that, for typical economic time series, the optimal bandwidth that minimizes a weighted average of type I and type II errors is larger by an order of magnitude than the …

Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips Jan 2008

Adaptive Estimation Of Autoregressive Models With Time-Varying Variances, Ke-Li Xu, Peter C. B. Phillips

Research Collection School Of Economics

Stable autoregressive models are considered with martingale differences errors scaled by an unknown nonparametric time-varying function generating heterogeneity. An important special case involves structural change in the error variance, but in most practical cases the pattern of variance change over time is unknown and may involve shifts at unknown discrete points in time, continuous evolution or combinations of the two. This paper develops kernel-based estimators of the residual variances and associated adaptive least squares (ALS) estimators of the autoregressive coefficients. Simulations show that efficiency gains are achieved by the adaptive procedure.
