Small And Medium Enterprises In Singapore And The New Economy, Boon Chye Lee, Wee Liang Tan Jan 2002

Small And Medium Enterprises In Singapore And The New Economy, Boon Chye Lee, Wee Liang Tan

Research Collection Lee Kong Chian School Of Business

From its earliest days as a British outpost, Singapore has relied heavily for its economic survival on its position as an entrepot trading centre. In the first decades after independence in 1965, economic strategy was focused on building infrastructure, attracting foreign direct investment, and export-led growth. The political commitment to openness in both trade and capital — and, more recently, labour — is one of the key features of a strategy that has delivered remarkable returns in terms of the economic well-being of the people of Singapore. Between 1961 and 1996 GDP per capita grew at an average rate of …

An Examination Of The Accuracy Of Slogans Related To Assessment Centres, Filip Lievens Jan 2002

An Examination Of The Accuracy Of Slogans Related To Assessment Centres, Filip Lievens

Research Collection Lee Kong Chian School Of Business

To diffuse new management fads or to promote existing management practices slogans are often used. In this study eight slogans regarding assessment centres were retrieved from brochures of consultancy agencies and were compared to empirical research. These slogans were that assessment centres work, are expensive, fair, have a potent influence on candidates, protide insight into candidates' personality, and are not prone to trainability effects. Other slogans include that trained assessors speak the same language and that candidate reactions are positive. Resulting from this comparison a more fine-grained picture of the strengths and weaknesses of assessment centres emerges. In particular, it …

Component-Based Development Using Uml, L. Zhao, Keng Siau Jan 2002

Component-Based Development Using Uml, L. Zhao, Keng Siau

Research Collection School Of Computing and Information Systems

Component-based software development (CBD) is a potential breakthrough for software engineering. Unified Modeling Language (UML) can potentially facilitate CBD design and modeling. Although many research projects concentrate on the conceptual interrelation of UML and CBD, few incorporate actual component frameworks into the discussion, which is critical for real-world software system design and modeling. This paper reviews component-based development, including the use of UML for modeling CBD. The paper then discusses the means by which UML extension mechanisms can be used to better support the popular component framework -- CORBA. Two other important component frameworks, DCOM and Web Services, are also …

Anatomy Of A Coupling Query In A Web Warehouse, Sourav S. Bhowmick, Sanjay Kumar Madria, Wee-Keong Ng, Ee Peng Lim Jan 2002

Anatomy Of A Coupling Query In A Web Warehouse, Sourav S. Bhowmick, Sanjay Kumar Madria, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

To populate a data warehouse specifically designed for Web data, i.e. web warehouse, it is imperative to harness relevant documents from the Web. In this paper, we describe a query mechanism called coupling query to glean relevant Web data in the context of our web warehousing system called Warehouse Of Web Data (WHOWEDA). Coupling query may be used for querying both HTML and XML documents. Some of the important features of our query mechanism are ability to query metadata, content, internal and external (hyperlink) structure of Web documents based on partial knowledge, ability to express constraints on tag attributes and …

Using Real Options Analysis For Evaluating Uncertain Investments In Information Technology: Insights From The Icis 2001 Debate, Paul P. Tallon, Robert J. Kauffman, Henry C. Lucas, Andrew B. Whinston, Kevin Zhu Jan 2002

Using Real Options Analysis For Evaluating Uncertain Investments In Information Technology: Insights From The Icis 2001 Debate, Paul P. Tallon, Robert J. Kauffman, Henry C. Lucas, Andrew B. Whinston, Kevin Zhu

Research Collection School Of Computing and Information Systems

Business and information systems (IS) executives continue to grapple with issues of risk and uncertainty in evaluating investments in information technology (IT). Despite the use of net present value (NPV) and other investment appraisal techniques, executives are often forced to rely on instinct when finalizing IT investment decisions. Recognizing the shortcomings of NPV, real options analysis has been suggested as an alternative approach, one that considers the risks associated with an investment while recognizing the ability of corporations to defer an investment until a later period or to make a partial investment instead. Responding to a growing interest in real …

Scaling Up Information Services For Development: A Framework Of Increasing Returns For Telecenters, Ted Tschang, Mathurot Chuladul, Thuy Thu Le Jan 2002

Scaling Up Information Services For Development: A Framework Of Increasing Returns For Telecenters, Ted Tschang, Mathurot Chuladul, Thuy Thu Le

Research Collection Lee Kong Chian School Of Business

Telecentres are an important type of information and communication technology (ICT) system particularly assisting rural and urban communities in developing countries, but the focus is often put on social development, sometimes on static economic returns, and rarely on dynamic economic aspects. This paper develops a basis for understanding the factors behind financial success in a dynamic setting based on the concept of increasing returns. This is applied to telecentres according to the stage of maturity of their information services. The framework is illustrated with literature- and interview-based cases, and will help an understanding of ways in which telecentres can scale-up …

Locating Tds In Policy Spaces: The Computational Text Analysis Of Dáil Speeches, Michael Laver, Kenneth Benoit Jan 2002

Locating Tds In Policy Spaces: The Computational Text Analysis Of Dáil Speeches, Michael Laver, Kenneth Benoit

Research Collection School of Social Sciences

This article adapts a new technique for the computerised analysis of political texts, previously used to analyse party manifestos, to the analysis of speeches made in a legislature. The benefits of computerised text analysis come from the ability to analyse, for the first time, complex and daunting electronic sources of text, such as the parliamentary record. This allows the systematic estimation of the policy positions of individual political actors, with huge benefits both for theory development and empirical analysis. In this article, the technique is used to analyse all 58 English language speeches made in the October 1991 confidence debate …

Barriers To The Advancement Of Modern Food Retail Formats: Theory And Measurement, Arieh Goldman, Seshan Ramaswami, Robert E. Krider Jan 2002

Barriers To The Advancement Of Modern Food Retail Formats: Theory And Measurement, Arieh Goldman, Seshan Ramaswami, Robert E. Krider

Research Collection Lee Kong Chian School Of Business

The recent expansion of global food retailers into emerging economies has made the study of food retail modernization especially relevant at this time. We present a framework to analyze limitations to market share growth of retail formats based on diffusion across consumer segments and by product category. We then propose a measurement approach, based on consumer surveys, that quantifies the impact of these processes on supermarket market share. Food retail modernization is then examined in Hong Kong by this approach for two points in time. In a 1995 diagnostic study, we find that geographic and economic segment diffusion of supermarkets …

A Small-Sample Overlapping Variance-Ratio Test, Yiu Kuen Tse, K. W. Ng, Xibin Zhang Jan 2002

A Small-Sample Overlapping Variance-Ratio Test, Yiu Kuen Tse, K. W. Ng, Xibin Zhang

Research Collection School Of Economics

The null distribution of the overlapping variance-ratio (OVR) test of the random-walk hypothesis is known to be downward biased and skewed to the right in small samples. As shown by Lo and MacKinlay (1989), the test under-rejects the null on the left tail seriously when the sample size is small. This unfortunate property adversely affects the applicability of the OVR test to macroeconomic time series, which usually have rather small samples. In this paper we propose a modified overlapping variance-ratio statistic and derive its exact mean under the normality assumption. We propose to approximate the small-sample distribution of the modified …

How Does Spousal Education Matter? Some Evidence From Cambodia, Tomoki Fujii, Sophal Ear Jan 2002

How Does Spousal Education Matter? Some Evidence From Cambodia, Tomoki Fujii, Sophal Ear

Research Collection School Of Economics

An econometric analysis of the World Food Programme Civil Insecurity Baseline Survey (1998) and Cambodia Socio-Economic Survey (1999) data is undertaken to examine the role of education and literacy in explaining household expenditure, as hypothesized in human capital theory where education is an investment with returns in the form of income. Explanatory variables were selected from a large set of observed variables by a systematic procedure to avoid the bias arising from arbitrary model selection. Spousal education and literacy are found to be significant explanatory variables in the determination of household expenditure, exceeding even the coefficients attached to the head …

Empirical Characteristic Function In Time Series Estimation, J. Knight, Jun Yu Jan 2002

Empirical Characteristic Function In Time Series Estimation, J. Knight, Jun Yu

Research Collection School Of Economics

Policymakers seeking to design efficient and smoothly functioning pension systems for their aging workforces are beginning to acknowledge the key importance of administrative expenses when formulating rules for pension plan structure and fee disclosure requirements. This study explores the links between retirement plan offerings and pension expenses for a wide range of private and public sector pension plan types, using an invaluable new data set on two thousand Australian pension funds. Our analysis indicates how pension plan design can strongly influence plan expenses and consequently eventual retirement security.

A Multivariate Generalized Autoregressive Conditional Heteroscedasticity Model With Time-Varying Correlations, Yiu Kuen Tse, Albert K.C. Tsui Jan 2002

A Multivariate Generalized Autoregressive Conditional Heteroscedasticity Model With Time-Varying Correlations, Yiu Kuen Tse, Albert K.C. Tsui

Research Collection School Of Economics

In this article we propose a new multivariate generalized autoregressive conditional heteroscedasticity (MGARCH) model with time-varying correlations. We adopt the vech representation based on the conditional variances and the conditional correlations. Whereas each conditional-variance term is assumed to follow a univariate GARCH formulation, the conditional-correlation matrix is postulated to follow an autoregressive moving average type of analog. Our new model retains the intuition and interpretation of the univariate GARCH model and yet satisfies the positive-definite condition as found in the constant-correlation and Baba-Engle-Kraft-Kroner models We report some Monte Carlo results on the finite-sample distributions of the maximum likelihood estimate of …

Forecasting Volatility In The New Zealand Stock Market, Jun Yu Jan 2002

Forecasting Volatility In The New Zealand Stock Market, Jun Yu

Research Collection School Of Economics

This study evaluates the performance of nine alternative models for predicting stock price volatility using daily New Zealand data. The competing models contain both simple models such as the random walk and smoothing models and complex models such as ARCH-type models and a stochastic volatility model. Four different measures are used to evaluate the forecasting accuracy. The main results are the following: (1) the stochastic volatility model provides the best performance among all the candidates; (2) ARCH-type models can perform well or badly depending on the form chosen: the performance of the GARCH(3,2) model, the best model within the ARCH …

A Gaussian Approach For Continuous Time Models Of Short Term Interest Rates, Jun Yu, Peter C. B. Phillips Jan 2002

A Gaussian Approach For Continuous Time Models Of Short Term Interest Rates, Jun Yu, Peter C. B. Phillips

Research Collection School Of Economics

This paper proposes a Gaussian estimator for nonlinear continuous time models of the short-term interest rate. The approach is based on a stopping time argument that produces a normalizing transformation facilitating the use of a Gaussian likelihood. A Monte Carlo study shows that the finite-sample performance of the proposed procedure offers an improvement over the discrete approximation method proposed by Nowman (1997). An empirical application to US and British interest rates is given.

Monitoring Process Variability With Symmetric Control Limits, Zhenlin Yang Jan 2002

Monitoring Process Variability With Symmetric Control Limits, Zhenlin Yang

Research Collection School Of Economics

Control charts for monitoring process variability, such as the R-chart and S-chart, do not have symmetric probability limits as the distribution of the sample variability is not normal. Hence, the usual zone rules can not be applied although it is still desirable to be able to use the information from more than one point in decision making. In this paper, a modified S-chart based on an optimal normalizing transformation of the sample variance is first introduced. The new chart is shown to have approximate symmetric probability limits and hence can be interpreted in the same way as that of a …

Trademark Exhaustion In The European Union: Community-Wide Or International? The Saga Continues, Irene Calboli Jan 2002

Trademark Exhaustion In The European Union: Community-Wide Or International? The Saga Continues, Irene Calboli

Research Collection Yong Pung How School Of Law

This Article analyzes the principle of "trademark exhaustion" or "first-sale rule" in the European Union (EU), with particular attention to the language and different interpretations of Article 7(1) of the First Council Directive 89 104 EEC of December 21, 1988. Traditionally, most jurisdictions define the extent of trademark exhaustion as either "national" or "international" exhaustion, depending on whether the rights granted by a mark are considered exhausted only in the domestic territory or also in foreign jurisdictions. Because of its nature as a regional integration of sovereign countries, the EU has historically favored a compromising approach toward the issue, and …

Internationalised Criminal Trial And Access To Justice, Mark Findlay Jan 2002

Internationalised Criminal Trial And Access To Justice, Mark Findlay

Research Collection Yong Pung How School Of Law

The influence of a human rights paradigm over the recent development of local and regional criminal justice concerns throughout Europe is indisputable. Essential to this is the commitment that crucial lay parties within the justice process (such as the accused and the victims) should have adequate access to common procedural protections of criminal justice. This paper takes this trend and measures its influence on the development of international criminal justice, the trial in particular. At the very least we argue that parallel concerns about fair trial in the international procedural context will endorse the importance of a fair trial paradigm …

Contract Law, Andrew Phang Jan 2002

Contract Law, Andrew Phang

Research Collection Yong Pung How School Of Law

As expected, the number of Singapore cases during the year under review impacting the law of contract is enormous. As I have mentioned in previous reviews, this is due to the fact that the law of contract permeates virtually all areas of the law of obligations – and, on occasion, beyond as well. I will therefore adopt the approach which has been adopted during previous years: which is to focus, in the main, on general principles. There have – as we shall see – been a few cases that are of especial significance. Not surprisingly, given the fact that the …

Mistake In Contract Law —Two Recent Cases, Andrew Phang Jan 2002

Mistake In Contract Law —Two Recent Cases, Andrew Phang

Research Collection Yong Pung How School Of Law

The doctrine of mistake in contract law has had a chequered history. Indeed, its very existence has been questioned (see, e.g., Slade, (1954) 70 L.Q.R. 385 and Atiyah and Bennion, (1961) 24 M.L.R. 421). But, like a bad penny that will not go away, the doctrine remains stubbornly embedded in the contractual landscape and has in fact witnessed a small revival of sorts in recent years (see, e.g., Clarion Ltd. v. National Provident Institution [2000] 2 All E.R. 265 (noted Phang, (2002) 1 J.O.R. 21)).

On Justificiation And Method In Law Reform: The Contracts (Rights Of Third Parties) Act 1999, Andrew Phang Jan 2002

On Justificiation And Method In Law Reform: The Contracts (Rights Of Third Parties) Act 1999, Andrew Phang

Research Collection Yong Pung How School Of Law

The present article, whilst focusing on the English Contracts (Rights of Third Parties) Act 1999, does not canvass the more specific details of that Act which have been dealt with quite comprehensively elsewhere. The focus of this article is broader and is dual in nature. It will examine, first, the justification for the 1999 Act and, in particular, attempts to respond to the critique that the Act is wholly anathema to the underlying justification of the doctrine of privity itself. It will also consider whether or not the 1999 Act is an effective improvement over the existing (as well as …

Market Power In Chinese Taipei: Laws, Policies And Treatments, Kung-Chung Liu, Yun-Peng Chu Jan 2002

Market Power In Chinese Taipei: Laws, Policies And Treatments, Kung-Chung Liu, Yun-Peng Chu

Research Collection Yong Pung How School Of Law

The experience of Chinese Taipei shows that opening up a previously protected market to new entrants can be a more effective and reliable way to enhance competition than regulating the behavior of dominant or monopolistic firms. Moreover, when opening up the market, the liberalizing measures adopted by government should be market-structure-neutral. That is, it should not try to dictate the direction and results of market competition. A more pressure-resistant mechanism should be designed to deal with market power, taking the form of a regime that is cross-sector, independent and collective in its decision-making, such as has been the case with …

Knowledge Management Mechanisms In E-Commerce: A Study Of Online Retailing And Auction Sites, Fiona Fui-Hoon Nah, Keng Siau, Yuhong Tian, Min Ling

Research Collection School Of Computing and Information Systems

Knowledge management is vital to a company's success in this e-commerce era. Not only has the topic of knowledge management attracted much research attention lately, but the management of customer knowledge is also becoming increasingly important. Despite its significance, few research studies have systematically investigated knowledge management in the e-commerce context. None of the studies we reviewed looked at how knowledge management mechanisms were employed in e-commerce. This research presents a comprehensive analysis of the knowledge management mechanisms employed by 14 e-commerce sites that were rated as being the best by Gomez.com, an independent Internet quality measurement firm. Specifically, we …
