Testing Conditional Uncorrelatedness, Liangjun Su, Aman Ullah Mar 2009

Testing Conditional Uncorrelatedness, Liangjun Su, Aman Ullah

Research Collection School Of Economics

We propose a nonparametric test for conditional uncorrelatedness in multiple-equation models such as seemingly unrelated regressions (SURs), multivariate volatility models, and vector autoregressions (VARs). Under the null hypothesis of conditional uncorrelatedness, the test statistic converges to the standard normal distribution asymptotically. We also study the local power property of the test. Simulation shows that the test behaves quite well in finite samples.

Risk, Firm Heterogeneity, And Dynamics Of Fdi Entry, Pao Li Chang, Chia-Hui Lu Mar 2009

Risk, Firm Heterogeneity, And Dynamics Of Fdi Entry, Pao Li Chang, Chia-Hui Lu

Research Collection School Of Economics

We study the dynamics of FDI entry under a setting with firm heterogeneity and FDI uncertainty. The risk of FDI failure depends positively on the complexity of production technology, negatively on the quality of infrastructure in the host country, and evolves over time with the extent of knowledge diffusion. The incorporation of FDI uncertainty leads to a non-monotonic relationship between technology complexity and the timing of FDI entry: firms with intermediate technology levels lead the first wave of FDI, which helps lower the investment uncertainty facing subsequent investors and induces a wider range of FDI entry in the second period. …

Tops-Only Domains, Shurojit Chatterji, Arunava Sen Mar 2009

Tops-Only Domains, Shurojit Chatterji, Arunava Sen

Research Collection School Of Economics

In this paper we consider the standard voting model with a finite set of alternatives A and n voters and address the following question: what are the characteristics of domains D that induce the property that every strategy-proof social choice function f : Dn → A satisfying unanimity, has the tops-only property? We first impose a minimal richness condition which ensures that for every alternative a, there exists an admissible ordering where a is maximal. We identify conditions on D that are sufficient for strategy-proofness and unanimity to imply tops onlyness in the general case of n voters and in …

The Efficiency Of Friendliness: Japanese Corporate Governance Succeeds Again Without Hostile Takeovers, Dan W. Puchniak Mar 2009

The Efficiency Of Friendliness: Japanese Corporate Governance Succeeds Again Without Hostile Takeovers, Dan W. Puchniak

Research Collection Yong Pung How School Of Law

It is widely assumed that hostile takeovers are a prerequisite for an efficient system of corporate governance. This assumption is false. Since the new millennium, Japan has transformed itself from being on the brink of one of the largest economic meltdowns in modern economic history to currently being in the midst of its longest period of postwar economic expansion (2002-2007). This astounding recovery was achieved without a single successful hostile takeover of a major Japanese company. True to its postwar tradition, corporate Japan has successfully restructured through government intervention, bank-driven reallocation of capital, and orchestrated and friendly mergers — the …

Fast Object Search On Road Networks, Ken C. K. Lee, Wang-Chien Lee, Baihua Zheng Mar 2009

Fast Object Search On Road Networks, Ken C. K. Lee, Wang-Chien Lee, Baihua Zheng

Research Collection School Of Computing and Information Systems

In this paper, we present ROAD, a general framework to evaluate Location-Dependent Spatial Queries (LDSQ)s that searches for spatial objects on road networks. By exploiting search space pruning technique and providing a dynamic object mapping mechanism, ROAD is very efficient and flexible for various types of queries, namely, range search and nearest neighbor search, on objects over large-scale networks. ROAD is named after its two components, namely, Route Overlay and Association Directory, designed to address the network traversal and object access aspects of the framework. In ROAD, a large road network is organized as a hierarchy of interconnected regional sub-networks …

Second Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: Organizational Strategies For Crises That Require High And Low Organizational Engagements, Augustine Pang, Yan Jin, Glen T. Cameron Mar 2009

Second Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: Organizational Strategies For Crises That Require High And Low Organizational Engagements, Augustine Pang, Yan Jin, Glen T. Cameron

Research Collection Lee Kong Chian School Of Business

Extending current theories in crisis communication, the authors have developed a moresystemic approach to understanding the role of emotions. The Integrated Crisis Mapping (ICM)model is based on a public-based, emotion-driven perspective where different crises aremapped on two continua, the organization’s engagement in the crisis and primary public’scoping strategy. This second-stage testing, representing the fourth in the series, found that ontop of discovering anxiety as a possible default emotion that publics feel in crises in an earlierstudy, the default response organizations embroiled in crises involving hostile takeovers,accidents, natural disasters, CEO retirement, rumor, and psychopathic acts, tend to adopt isqualified rhetoric-mix stance …

Tapping The Grapevine: A Closer Look At Word-Of-Mouth As A Recruitment Source, Greet Van Hoye, Filip Lievens Mar 2009

Tapping The Grapevine: A Closer Look At Word-Of-Mouth As A Recruitment Source, Greet Van Hoye, Filip Lievens

Research Collection Lee Kong Chian School Of Business

To advance knowledge of word-of-mouth as a company-independent recruitment source, this study draws on conceptualizations of word-of-mouth in the marketing literature. The sample consisted of 612 potential applicants targeted by the Belgian Defense. Consistent with the recipient-source framework, time spent receiving positive word-of-mouth was determined by the traits of the recipient (extraversion and conscientiousness), the characteristics of the source (perceived expertise), and their mutual relationship (tie strength). Only conscientiousness and source expertise were determinants of receiving negative word-of-mouth. In line with the accessibility-diagnosticity model, receiving positive employment information through word-of-mouth early in the recruitment process was positively associated with perceptual …

Compromising On Consideration In Singapore: Gay Choon Ing V Loh Sze Ti Terence Peter, Yihan Goh Mar 2009

Compromising On Consideration In Singapore: Gay Choon Ing V Loh Sze Ti Terence Peter, Yihan Goh

Research Collection Yong Pung How School Of Law

It is not often that a judgment contains a reference to Aristotle’s work or a coda at its conclusion. The recent Singapore Court of Appeal judgment of Gay Choon Ing v Loh Sze Ti Terence Peter (delivered by Andrew Phang JA) contained both, the latter of which an extensive judicial exposition on the difficulties (and tentative solutions) relating to the contractual doctrine of consideration. This re-evaluation of consideration at the slightest opportunity is unsurprising, given the conceptual problems that have afflicted the doctrine.There have been various judicial solutions, generally capable of classification into two distinct types: first, through an internal …

Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee Mar 2009

Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee

Research Collection School of Social Sciences

This article examines how multiracial individuals negotiate their different and sometimes conflicting racial identities. Drawing from previous work on bicultural identity integration (see Benet-Martinez and Haritatos, 2005), we proposed a new construct, multiracial identity integration (MII), to measure individual differences in perceptions of compatibility between multiple racial identities. We found that MII is composed of two independent subscales: that describes whether different racial identities are perceived as disparate, and that describes whether different racial identities are perceived as in conflict. We also found that recalling positive multiracial experiences increased MII, while recalling negative multiracial experiences decreased MII. These findings have …

Intergenerational Earnings Mobility In Singapore And The United States, Irene Y. H. Ng, Xiaoyi Shen, Kong Weng Ho Mar 2009

Intergenerational Earnings Mobility In Singapore And The United States, Irene Y. H. Ng, Xiaoyi Shen, Kong Weng Ho

Research Collection School Of Economics

This study compared intergenerational earnings mobility in Singapore and the United States by replicating the sample criteria in the Singapore National Youth Survey on the U.S. Panel Study of Income Dynamics. The mean estimated earnings elasticities are almost identical: 0.26 in Singapore and 0.28 in the United States. Transformed to 0.44 and 0.47 respectively to reflect permanent status, mobility in the two countries is moderately low compared internationally. The finding of similar mobility is not surprising given that the two countries have similar economic realities, welfare systems, education regimes, and labor structures. Policy makers face the daunting challenge of overcoming …

Make The Implicit Explicit: Affirming Right To Vote In The Constitution Would Pre-Empt The Possibility Of Abuse By Future Govts, Jack Tsen-Ta Lee Feb 2009

Make The Implicit Explicit: Affirming Right To Vote In The Constitution Would Pre-Empt The Possibility Of Abuse By Future Govts, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

There are sound reasons to set out explicitly and entrench in the Singapore Constitution the right to vote and key elements of the way elections are held. While a future government might not remove them entirely, it might derogate from them to the extent that they become unrecognizable.

Can Liquidity Shifts Explain The Lockup Expiration Effect In Stock Returns?, Chandrasekhar Krishnamurti, Avanidhar Subrahmanyam, Tiong Yang Thong Feb 2009

Can Liquidity Shifts Explain The Lockup Expiration Effect In Stock Returns?, Chandrasekhar Krishnamurti, Avanidhar Subrahmanyam, Tiong Yang Thong

Research Collection Lee Kong Chian School Of Business

Several studies on the expiration of IPO lockups document a strong negative reaction even though the unlock event is devoid of any informational content. The empirical finding has remained a conundrum. In this paper, we find that changes in liquidity can account for the observed stock price reaction around lockup expiration. Specifically, firms which show improvement in liquidity subsequent to the unlock day experience positive abnormal returns in the post-expiration period, and vice versa. Another interesting conclusion that emerges from our research is that liquidity changes can predict future abnormal returns. Our results remain robust to the use of alternate …

Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy Feb 2009

Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy

Research Collection School Of Economics

A dynamic factor model is applied to a large panel dataset of Singapore’s macroeconomic variables and global economic indicators with the initial objective of analyzing business cycles in a small open economy. The empirical results suggest that four common factors are present in the quarterly time series, which can broadly be interpreted as world, regional, electronics and domestic economic cycles. The estimated factor model explains well the observed fluctuations in real economic activity and price inflation, leading us to use it in forecasting Singapore’s business cycles. We find that the forecasts generated by the factors are generally more accurate than …

The Dark Triad: Facilitating A Short-Term Mating Strategy In Men, Peter K. Jonason, Norman P. Li, Gregory D. Webster, David P. Schmitt Feb 2009

The Dark Triad: Facilitating A Short-Term Mating Strategy In Men, Peter K. Jonason, Norman P. Li, Gregory D. Webster, David P. Schmitt

Research Collection School of Social Sciences

This survey (N=224) found that characteristics collectively known as the Dark Triad (i.e. narcissism, psychopathy and Machiavellianism) were correlated with various dimensions of short-term mating but not long-term mating. The link between the Dark Triad and short-term mating was stronger for men than for women. The Dark Triad partially mediated the sex difference in short-term mating behaviour. Findings are consistent with a view that the Dark Triad facilitates an exploitative, short-term mating strategy in men. Possible implications, including that Dark Triad traits represent a bundle of individual differences that promote a reproductively adaptive strategy are discussed. Findings are discussed in …

Proclaiming Trade Policy: 'Delegated Unilateral Powers' And The Limits On Presidential Unilateral Enactment Of Trade Policy, Brandon Rottinghaus, Elvin T. Lim Feb 2009

Proclaiming Trade Policy: 'Delegated Unilateral Powers' And The Limits On Presidential Unilateral Enactment Of Trade Policy, Brandon Rottinghaus, Elvin T. Lim

Research Collection School of Social Sciences

This article examines presidential proclamations on trade policy, a category of presidential unilateral power that we call delegated unilateral power that is used frequently in creating or modifying trade policy, between the period1974 and 2006 and tests the boundaries of the explanations predicted by the unilateral powers literature. We also find that the use of proclamations on trade policy is independent of the partisan balance in Congress. The use of proclamations modifying policies was the only tactic that comported with predicted actions from the unilateral presidency. Therefore, contrary to the expectations of the unilateral presidency, presidents are not unrestrained political …

Toward A More Complete Understanding Of The Link Between Multicultural Experience And Creativity, William W. Maddux, Angela K.-Y. Leung, Chi-Yue Chiu, Adam D. Galinsky Feb 2009

Toward A More Complete Understanding Of The Link Between Multicultural Experience And Creativity, William W. Maddux, Angela K.-Y. Leung, Chi-Yue Chiu, Adam D. Galinsky

Research Collection School of Social Sciences

Responds to G. J. Rich's comments on the current author's original article which presented evidence supporting the idea that multicultural experience can facilitate creativity. Rich has argued that our review, although timely and important, was somewhat limited in scope, focusing mostly on smaller forms of creativity ("little c": e.g., paper-and-pencil measures of creativity) as well as on larger forms of multicultural experience ("Big M": e.g., living in a foreign country). We agree with many aspects of Rich's assessment. The issue of whether different forms of multicultural experience can affect Big C creativity is of interest to both scholars and laypeople …

A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu Jan 2009

A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu

Research Collection School of Economics

A general dynamical cluster identification framework including both modeling and computation is developed.The earthquake declustering problem is studied to demonstrate how this framework applies.A stochastic model is proposed for earthquake occurrences that considers the sequence of occurrencesas composed of two parts: earthquake clusters and single earthquakes. We suggest that earthquake clusterscontain a “mother quake” and her “offspring.” Applying the filtering techniques, we use the solution offiltering equations as criteria for declustering. A procedure for calculating maximum likelihood estimations(MLE’s) and the most likely cluster sequence is also presented.

Traditions Of Philanthropic Order, Christine Dunn Henderson Jan 2009

Traditions Of Philanthropic Order, Christine Dunn Henderson

Research Collection School of Social Sciences

Individuals act more or less simultaneously as economic agents, citizens, and participants in civil society. Their interactions and their ways of fulfilling these roles take many forms. Not all of them can be said to be self-organizing, yet in several instances patterns of organization emerge spontaneously without being deliberately designed. Of course, the market economy—or “catallaxy,” as F. A. Hayek called it—remains the best example of such “spontaneous orders.” But there are others. Gus diZerega (2000), for example, has identified science and democracy as being similarly constituted by self-referential, self-organizing (some authors prefer the term autopoietic) processes. In this paper …

Law School And The Making Of The Student Into A Lawyer: Transformation Of First Year Law Students In The National University Of Singapore, Seow Hon Tan Jan 2009

Law School And The Making Of The Student Into A Lawyer: Transformation Of First Year Law Students In The National University Of Singapore, Seow Hon Tan

Research Collection Yong Pung How School Of Law

This paper examines the impact of legal education and law school on the student's moral development and conception of professional identity, through an empirical study of first year law students of the Class of 2010 at the National University of Singapore. The project aims to increase consciousness of how law school remakes students and develops the moral and professional identity of future lawyers, and to facilitate a dialogue that reshapes legal education to achieve its aims. Given that legal education in Singapore is similar to that in other law schools in common law jurisdictions, the analysis is, with allowances for …

Corporate Tax, Capital Structure, And The Accessibility Of Bank Loans: Evidence From China, Liansheng Wu, Heng Yue Jan 2009

Corporate Tax, Capital Structure, And The Accessibility Of Bank Loans: Evidence From China, Liansheng Wu, Heng Yue

Research Collection School Of Accountancy

In this paper, we investigate whether listed firms in China adjust their capital structure in response to an increase in the corporate taxrate. Although theories of capital structure suggest that corporate tax is an important determinant of capital structure, how exogenouschanges of the tax rate affect firms’ leverage decisions has not been fully explored. We examine a unique circumstance in which the Chinesegovernment increased the corporate tax rate of firms that had previously received local government tax rebates. The evidence indicatesthat these firms increased their leverage when the corporate tax rate increased. Further investigation suggests that the adjustment ofleverage was …
