Venture Capital And Economic Growth: An Industry Overview And Singapore's Experience, Francis Koh, Winston T. H. Koh Nov 2002

Venture Capital And Economic Growth: An Industry Overview And Singapore's Experience, Francis Koh, Winston T. H. Koh

Research Collection Lee Kong Chian School Of Business

This paper provides an overview of the venture capital industry, and its development in Asia and Singapore. Venture capital plays an important role in innovation and economic growth. Indeed, the resurgence of the United States as a technology leader is intimately linked to the success of Silicon Valley. As Singapore enters the next phase of economic development, the creation of internal engines of growth is an urgent task. The Singapore government has done much to provide an environment for entrepreneurship to thrive. Its success at replicating the Silicon Valley culture will be important for Singapore's future economic success.

Tax Cuts, Employment And Asset Prices: A Real Intertemporal Model, Hian Teck Hoon, Edmund S. Phelps Nov 2002

Tax Cuts, Employment And Asset Prices: A Real Intertemporal Model, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

We determine the effects of a delayed or immediate tax cut with or without a sunset feature in a real customer-market, nonRicardian economy. Our model incorporates both the supply-sider channel, through which reduced wage income taxes stimulate work effort, as well as the Feldstein-Rubin-Summers channel, through which cuts in income tax, in widening the deficit and thus driving up future short real interest rates, has a chilling effect on present and future investment, so reducing growth and employment on that account. After establishing conditions under which fiscal policy is sustainable, we first show that a delayed tax cut may depress …

Dynamical Evolutionary Psychology: Mapping The Domains Of The New Interactionist Paradigm, Douglas T. Kenrick, Jon K. Maner, Jon Butner, Norman P. Li, D. Vaughn Becker, Mark Schaller Nov 2002

Dynamical Evolutionary Psychology: Mapping The Domains Of The New Interactionist Paradigm, Douglas T. Kenrick, Jon K. Maner, Jon Butner, Norman P. Li, D. Vaughn Becker, Mark Schaller

Research Collection School of Social Sciences

Dynamical systems and evolutionary theories have both been proposed as integrative approaches to psychology. These approaches are typically applied to different sets of questions. Dynamical systems models address the properties of psychological systems as they emerge and change over time; evolutionary models address the specific functions and contents of psychological structures. New insights can be achieved by integrating these two paradigms, and we propose a framework to begin doing so. The framework specifies a set of six evolutionarily fundamental social goals that place predictable constraints on emergent processes within and between individuals, influencing their dynamics over the short-term, and across …

A Corrected Plug-In Method For The Quantile Confidence Interval Of A Transformed Regression, Zhenlin Yang, Yiu Kuen Tse Nov 2002

A Corrected Plug-In Method For The Quantile Confidence Interval Of A Transformed Regression, Zhenlin Yang, Yiu Kuen Tse

Research Collection School Of Economics

In this paper we propose an analytically corrected plug-in method for constructing confidence intervals of the conditional quantiles of a response variable with data transformation. The method can be applied to (i) a general conditional regression quantile, (ii) a general monotonic transformation, and (iii) a transformation model with heteroscedastic errors. Our results extend those in Yang (2002a), in which the median of a response variable under the Box-Cox transformation with homoscedastic errors was considered. A Monte Carlo experiment is conducted to compare the performance of the corrected plug-in method, the plug-in method and the delta method. The corrected plug-in method …

Lay Theories And Evaluation-Based Organization Of Impressions: An Application Of The Memory Search Paradigm, Yuk-Yue Tong, Chi-Yue Chiu Nov 2002

Lay Theories And Evaluation-Based Organization Of Impressions: An Application Of The Memory Search Paradigm, Yuk-Yue Tong, Chi-Yue Chiu

Research Collection School of Social Sciences

People may believe that personal attributes are fixed entities that cannot be changed (hold an entity theory). Alternatively, they may believe that qualities of a person are malleable (hold an incremental theory). In the present research, the authors used Sternberg's (1966) memory search task to examine entity and incremental theorists' cognitive strategies in memory search. It was hypothesized that entity theorists, who have a greater tendency to make spontaneous evaluation of people, would organize impressions in short-term memory according to whether the stimulus persons are positively or negatively evaluated. Next, they might compare the probe only to the stimulus persons …

Market Segmentation And Information Values Of Earnings Announcements: Some Empirical Evidence From An Event Study On The Chinese Stock Market, Yu Gao, Yiu Kuen Tse Oct 2002

Market Segmentation And Information Values Of Earnings Announcements: Some Empirical Evidence From An Event Study On The Chinese Stock Market, Yu Gao, Yiu Kuen Tse

Research Collection School Of Economics

This paper investigates the trading activities of two distinct classes of shareholders, namely, the Chinese domestic investors and the foreign investors in the segmented Chinese A-share and B-share markets, respectively. We conduct an event study on the annual earnings announcements based on two different accounting standards: IAS and PRC GAAP. The earnings announcements based on IAS and PRC GAAP are value relevant. The investors in the B-share market react to both the IAS and PRC GAAP earnings announcements, while the investors in the A-share market pay more attention to the PRC GAAP earnings reports. In the B-share market, positive abnormal …

On The Performance Of Geometric Chart With Estimated Control Limits, Zhenlin Yang, Min Xie, Vellaisamy Kuralmani, Kwok-Leung Tsui Oct 2002

On The Performance Of Geometric Chart With Estimated Control Limits, Zhenlin Yang, Min Xie, Vellaisamy Kuralmani, Kwok-Leung Tsui

Research Collection School Of Economics

The control chart based on the geometric distribution (geometric chart) has been shown to be competitive with p- or np-charts for monitoring the proportion nonconforming, especially for applications in high quality manufacturing environments. However, implementing a geometric chart is often based on the assumption that the in-control proportion nonconforming is known or accurately estimated for a high quality process, an accurate parameter estimate may require a very large sample size that is seldom available. In this paper we investigate the sample size effect when the proportion nonconforming is estimated. An analytical approximation is derived to compute shift detection probabilities and …

Estimation Of Hyperbolic Diffusion Using Mcmc Method, Yiu Kuen Tse, Jun Yu, X. B. Chang Sep 2002

Estimation Of Hyperbolic Diffusion Using Mcmc Method, Yiu Kuen Tse, Jun Yu, X. B. Chang

Research Collection School of Economics

In this paper we propose a Bayesian method for estimating hyperbolic diffusion models. The approach is based on the Markov Chain Monte Carlo (MCMC) method after discretization via the Milstein scheme. Our simulation study shows that the hyperbolic diffusion exhibits many of the stylized facts about asset returns documented in the financial econometrics literature, such as a slowly declining autocorrelation function of absolute returns. We demonstrate that the MCMC method provides a useful tool to analyze hyperbolic diffusions. In particular, quantities of posterior distributions obtained from MCMC outputs can be used for statistical inferences

Social Entrepreneurship In Singapore, Wee Liang Tan, Teck Meng Tan Sep 2002

Social Entrepreneurship In Singapore, Wee Liang Tan, Teck Meng Tan

Research Collection Lee Kong Chian School Of Business

Social entrepreneurship is a new phenomenon in Singapore. Unlike the US, where there are entrepreneurship programs offered at various ACCSB accredited universities such programs do not as yet exist in Asia. The motivations for social entrepreneurship in Asia differ from those in developed countries. While as social entrepreneurship often stem from the social agenda of successful entrepreneurs who are motivated to repay society, the recent trend of social entrepreneurship in Asia may stem from initiatives directed at political liberalisation and the development of civil society on the part of existing governments. The Singapore government in 1997 introduced a series of …

The General Dominance Of Lottery Over Waiting-Line Auction, Winston T. H. Koh, Zhenlin Yang, Lijing Zhu Sep 2002

The General Dominance Of Lottery Over Waiting-Line Auction, Winston T. H. Koh, Zhenlin Yang, Lijing Zhu

Research Collection School Of Economics

This paper examines the allocative efficiency of two popular non-price allocation mechanisms — the lottery (random allocation) and the waiting-line auction (queue system) — for the cases where consumers possess identical time costs (the homogeneous case), and where time costs are correlated with time valuations (the heterogeneous case). We show that the relative efficiency of the two mechanisms depends critically on the scarcity factor (measured by the ratio of the number of objects available for allocation over the number of participants) and on the shape of the distribution of valuations. We obtain a set of analytical results showing that the …

Increasing Transparency In Government, Ann Florini Sep 2002

Increasing Transparency In Government, Ann Florini

Research Collection School of Social Sciences

The article focuses on the transparency in the government and investigates how transparency is related directly to achieving and maintaining international peace, by transforming the security relationship between countries. It also examines transparency's indirect role in contributing to legitimate and effective governance and explores the trends in transparency in national politics, international organizations, and environmental management. Information is the lifeblood of both democracies and markets. Without information, citizens have no basis upon which to evaluate their representatives or voice their opinions, and both elections and the very process of representation become a meaningless sham. Without information, the financial markets upon …

Endogenous Tariff Formation With Intra-Industry Trade, Pao-Li Chang Aug 2002

Endogenous Tariff Formation With Intra-Industry Trade, Pao-Li Chang

Research Collection School Of Economics

Previous theoretical contributions on endogenous tariff formation have focused on trade models with homogeneous goods and constant returns to scale. This paper investigates the political equilibrium of trade policy when economic structure is instead characterized by differentiated products and increasing returns to scale and there exists intra-industry trade. The result shows that endogenous tariffs are positive for all industries with non-negligible shares of world production. However, the level of protection is less than the optimal tariff that would otherwise be imposed by a benevolent government in an unorganized industry, and higher in an organized industry. The protection provided to all …

Interference Between Verbal Concept Formation And Spatial Mental Rotation In Female Subjects, Tamas Makany, Kázmér Karadi, János Kallai, Lynn Nadel Aug 2002

Interference Between Verbal Concept Formation And Spatial Mental Rotation In Female Subjects, Tamas Makany, Kázmér Karadi, János Kallai, Lynn Nadel

Research Collection Lee Kong Chian School Of Business

In this study the relation between spatial cognition and verbal intelligence abilities was examined in case of 52 women. Interference between mental rotation performance and verbal intelligence scores was found. Women with good verbal abilities have lower scores in mental rotation tasks than subjects with poorer verbal abilities. This finding is in accordance with some basic models of a dual-coding system. The spatial functions represented in mental rotation interfered with verbal-based concept formation and lexical knowledge in college women.

Trying To Understand The Different Pieces Of The Construct Validity Puzzle Of Assessment Centers: An Examination Of Assessor And Assessee Effects, Filip Lievens Aug 2002

Trying To Understand The Different Pieces Of The Construct Validity Puzzle Of Assessment Centers: An Examination Of Assessor And Assessee Effects, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This study examined the effects of assessor-related factors (i.e., type of assessor) and assessee-related factors (i.e., type of assessee profile) on the construct validity of assessment center ratings. In particular, 3 types of assessors (26 industrial/organizational [I/O] psychologists, 20 managers, and 27 students), rated assessee performances that varied according to cross-exercise consistency (i.e., relatively inconsistent vs. relatively consistent) and dimension differentiation (relatively undifferentiated vs. relatively differentiated). Construct validity evidence was established for only one assessee profile and only in the I/O psychologist and managerial samples. More generally, these results indicate that 3 factors (poor design, assessor unreliability, and especially cross-situational …

Trust In Leadership: Meta-Analytic Findings And Implications For Research And Practice, Kurt T. Dirks, Donald L. Ferrin Aug 2002

Trust In Leadership: Meta-Analytic Findings And Implications For Research And Practice, Kurt T. Dirks, Donald L. Ferrin

Research Collection Lee Kong Chian School Of Business

In this study, the authors examined the findings and implications of the research on trust in leadership that has been conducted during the past 4 decades. First, the study provides estimates of the primary relationships between trust in leadership and key outcomes, antecedents, and correlates (k = 106). Second, the study explores how specifying the construct with alternative leadership referents (direct leaders vs. organizational leadership) and definitions (types of trust) results in systematically different relationships between trust in leadership and outcomes and antecedents. Direct leaders (e.g., supervisors) appear to be a particularly important referent of trust. Last, a theoretical framework …

Making Justice Sense Of Local-Expatriate Compensation Disparity: Mitigation By Local Referents, Ideological Explanations, And Interpersonal Sensitivity In China-Foreign Joint Ventures, Chao C. Chen, Jaepil Choi, Chu-Cheng Chi Aug 2002

Making Justice Sense Of Local-Expatriate Compensation Disparity: Mitigation By Local Referents, Ideological Explanations, And Interpersonal Sensitivity In China-Foreign Joint Ventures, Chao C. Chen, Jaepil Choi, Chu-Cheng Chi

Research Collection Lee Kong Chian School Of Business

We examined how local employees of international joint ventures (IJVs) perceived disparity between their compensation and foreign expatriates' compensation from equity theory and social justice perspectives. Chinese locals perceived less fairness when comparing their compensation with expatriates' than when comparing it with other locals'. However, fairness vis-a-vis expatriates increased if the locals were compensated higher than their peers in other IJVs or endorsed ideological explanations for expatriates' advantage. Furthermore, expatriates' interpersonal sensitivity toward locals reduced the effect of disparity on perceived fairness. Finally, perceived compensation fairness was related positively to compensation satisfaction but negatively to intentions to quit.

The Evolution And Utilization Of The Gatt/Wto Dispute Settlement Mechanism, Pao Li Chang Aug 2002

The Evolution And Utilization Of The Gatt/Wto Dispute Settlement Mechanism, Pao Li Chang

Research Collection School Of Economics

This paper attempts to study the usage of the GATT/WTO dispute settlement mechanism and to explain its patterns across different regimes and decades, using a unified theoretical model. This study first explores the role of the degree of legal controversy over a panel ruling in determining countries’ incentives to block/appeal a panel report under the GATT/WTO regime. The model is able to explain the surge in blocking incidence during the 1980s over the preceding GATT years and the immense frequency at which the new appellate procedure under the WTO is invoked. Furthermore, a two-sided asymmetric information framework is used to …

A Misspecification-Robust Impulse Response Estimator, Pao Li Chang, Shinichi Sakata Aug 2002

A Misspecification-Robust Impulse Response Estimator, Pao Li Chang, Shinichi Sakata

Research Collection School Of Economics

Impulse response analysis is typically conducted by fitting an autoregression model to a time series and calculating the moving average coefficients implied by the estimated autoregression model. The possible shape and persistence of the impulse response function implied by a parsimonious autoregression specification are very limited. This paper proposes an alternative approach to estimating impulse response function, which is asymptotically valid yet is less sensitive to model misspecifications in small samples. The small sample advantages of the proposed impulse response estimator over the conventional approach is demonstrated by Monte Carlo studies. The large sample validity of the proposed estimator is …

In Search Of Permanent Homes: Singapore's House Churches And The Politics Of Space, Lily Kong Aug 2002

In Search Of Permanent Homes: Singapore's House Churches And The Politics Of Space, Lily Kong

Research Collection School of Social Sciences

This paper focuses on one category of the 'unofficially sacred'-namely, those secular spaces which are used for worship and, in particular, residential spaces which are turned into 'house churches'. Using the case study of a house church in Singapore, the paper examines issues about the politics of religion in urban landscapes in a secular and simultaneously multireligious state. Contrary and in addition to current wisdoms about the politics of religious space, it is argued that various politics are observed: a politics of inclusion; a politics of hybridisation and in-betweenness; a politics of appropriation and nationalisation; and a politics of impermanence …

G-Portal : A Map-Based Digital Library For Distributed Geospatial And Georeferenced Resources, Ee Peng Lim, Dion Hoe-Lian Goh Jul 2002

G-Portal : A Map-Based Digital Library For Distributed Geospatial And Georeferenced Resources, Ee Peng Lim, Dion Hoe-Lian Goh

Research Collection School Of Computing and Information Systems

As the World Wide Web evolves into an immense information network, it is tempting to build new digital library services and expand existing digital library services to make use of web content. In this paper, we present the design and implementation of G-Portal, a web portal that aims to provide digital library services over geospatial and georeferenced content found on the World Wide Web. G-Portal adopts a map-based user interface to visualize and manipulate the distributed geospatial and georeferenced content. Annotation capabilities are supported, allowing users to contribute geospatial and georeferenced objects as well as their associated metadata. The other …

Exchange-Rate Systems And Interest-Rate Behavior: The Experience Of Hong Kong And Singapore, Yiu Kuen Tse, Paul S. L. Yip Jul 2002

Exchange-Rate Systems And Interest-Rate Behavior: The Experience Of Hong Kong And Singapore, Yiu Kuen Tse, Paul S. L. Yip

Research Collection School Of Economics

In this paper we consider the implications of the two different exchange-rate systems in Hong Kong (HK) and Singapore (SP) on the economic performance of these two economies. While HK has a pegged exchange-rate regime under a currency board system (CBS), SP has a managed-float system with monitoring band. We examine whether the managed-float system of SP provides an advantage over the rigid CBS of HK in mitigating the recession caused by the Asian Financial Crisis (AFC), and the implications of the differences in the exchange-rate systems on interest-rate behaviour. Our empirical results show that the monitoring band system in …

The Impact Of Housing Prices On Aggregate Consumption: Evidence From An East Asian City-State, Sock-Yong Phang Jul 2002

The Impact Of Housing Prices On Aggregate Consumption: Evidence From An East Asian City-State, Sock-Yong Phang

Research Collection School Of Economics

Using aggregate consumption data for Singapore, this paper rejects the life-cycle/permanent income and myopia hypotheses as explanations for aggregate consumption behavior. We confirm the presence of liquidity constraints from the asymmetric reaction of consumption to income increases vis-a-vis income declines. When we allow for asymmetric response, anticipated house price increases appear to have a dampening effect on aggregate consumption while declines in expected house price growth also had a negative effect on consumption, although the results are statistically insignificant. There is no evidence that the housing price increases have produced either wealth or collateral enhancement effects on consumption.

A Modified Family Of Power Transformations, Zhenlin Yang Jul 2002

A Modified Family Of Power Transformations, Zhenlin Yang

Research Collection School Of Economics

A modified family of power transformation, called the Dual Power Transformation, is proposed, which overcomes the truncation problem of the Box-Cox power transformation. The new transformation possesses properties similar to those of the Box-Cox power transformation. It generates a rich family of distributions that is seen to be very useful in modeling and analysis of economic durations and medical/engineering event-times. Further, it gives rise to transformed (regression) models such that all the standard asymptotic results of the maximum likelihood theory apply. Empirical results presented are more favorable to the new transformation than to the Box-Cox power transformation in terms of …

Optimal Organizational Design In A Dichotomous-Choice Project Selection Model, Winston T. H. Koh Jul 2002

Optimal Organizational Design In A Dichotomous-Choice Project Selection Model, Winston T. H. Koh

Research Collection School Of Economics

This paper studies collective decision making in the context of a project selection model. We derive the optimal decision architecture when marginal decision costs are present, and investigate the circumstances under which the hierarchy and polyarchy exist as optimal sequential architectures. Our analysis extends previous results on optimal committee decision-making to a sequential setting, and further demonstrates the fragility of the hierarchy and polyarchy as optimal architectures.
