Instance Based Attribute Identification In Database Integration, Ee Peng Lim, Cecil Chua, Roger Hsiang-Li Chiang Jan 2003

Instance Based Attribute Identification In Database Integration, Ee Peng Lim, Cecil Chua, Roger Hsiang-Li Chiang

Research Collection School Of Computing and Information Systems

Most research on attribute identification in database integration has focused on integrating attributes using schema and summary information derived from the attribute values. No research has attempted to fully explore the use of attribute values to perform attribute identification. We propose an attribute identification method that employs schema and summary instance information as well as properties of attributes derived from their instances. Unlike other attribute identification methods that match only single attributes, our method matches attribute groups for integration. Because our attribute identification method fully explores data instances, it can identify corresponding attributes to be integrated even when schema information …

Effects Of Electronic Trading On The Hang Seng Index Futures Market, Joseph Fung, Donald Lien, Yiuman Tse, Yiu Kuen Tse Jan 2003

Effects Of Electronic Trading On The Hang Seng Index Futures Market, Joseph Fung, Donald Lien, Yiuman Tse, Yiu Kuen Tse

Research Collection School Of Economics

This paper investigates the effects of the migration of the Hang Seng Index futures from open-outcry trading to electronic trading. Using trade data over a window of six months we find evidence that, after the migration, the bid-ask spread of the futures contract decreases and the contribution of the futures price in information transmission increases. Furthermore, the asymmetry in volatility spillover reduces and the open interests of the futures market become smaller. These results suggest that the anonymity in trading and the higher speed of order execution in the electronic trading system attract informed traders to the futures market and …

Education, Technological Progress And Economic Growth, Winston T. H. Koh, Hing-Man Leung Jan 2003

Education, Technological Progress And Economic Growth, Winston T. H. Koh, Hing-Man Leung

Research Collection School Of Economics

An important role of education – and the resultant accumulation of human capital – for a less-developed economy is to facilitate technology diffusion in order for it to catch up with developed economies. This paper presents a model linking education, the accumulation of physical capital and technological progress. In the model, investment in education and the accumulation of physical capital are complementary, and intertwine with the technology progress through related effects on technology diffusion and the expansion of the technology frontier. The allocation of effort to education, the optimal savings rate and the technology gap are endogenously determined in the …

Competitiveness And Price Convergence On The Internet: Evidence From The Online Dvd Market, Xiaolin Xing, Fang Fang Tang, Zhenlin Yang Jan 2003

Competitiveness And Price Convergence On The Internet: Evidence From The Online Dvd Market, Xiaolin Xing, Fang Fang Tang, Zhenlin Yang

Research Collection School Of Economics

We compare the pricing behavior between online branches of traditional retailers (MCR) and pure Internet retailers (Dotcom) in the DVD market. Based on a set of panel data from July 5, 2000 to June 11, 2001, we find that the average price of the MCRs is about 11.2% higher than that of the Dotcoms. Further statistical analyses on the market dynamics of price trends show that the prices of the Dotcoms went up with time much faster than the prices of the MCRs, which points to a possibility that eventually both types of retailers may charge similar prices on average. …

External Debt And Worsening Business Cycles In Less Developed Countries, Hing-Man Leung Jan 2003

External Debt And Worsening Business Cycles In Less Developed Countries, Hing-Man Leung

Research Collection School Of Economics

Less developed countries (LDCs) have seen considerable business cycles in recent decades. At the same time they have significantly increased their external-debt-to-GDP ratios. It seems natural to suspect that increased indebtedness and the amplified cycles are linked. The paper presents a simple macroeconomic model to formalize this connection. External debt is the novelty of this model. The paper's main contribution is to calibrate the dynamic parameter using the World Development Indicator. It is found that the LDC dynamic behavior is generally non-oscillatory. Alarmingly though, the dynamic convergent system in the 1970s has been replaced by one of divergence.

Strategic Development Of Airport And Rail Infrastructure: The Case Of Singapore, Sock-Yong Phang Jan 2003

Strategic Development Of Airport And Rail Infrastructure: The Case Of Singapore, Sock-Yong Phang

Research Collection School Of Economics

This article recounts how a number of strategic infrastructure investment decisions in airport and rail development taken by the Singapore government were at variance with recommendations emerging from cost-benefit analysis, but were considered necessary to support external competitiveness. This link between infrastructure provision and economic development may require decision makers to assess the trade-off between prudent macro-economic planning and efficient micro-economic management for major projects. In the case of airport hubs, the most difficult assessment might be the game consideration of how much, and how far ahead, excess capacity is needed to ensure the dominance of the hub.

Exclusion Bias In Sample-Selection Model Estimators, Myoung-Jae Lee Jan 2003

Exclusion Bias In Sample-Selection Model Estimators, Myoung-Jae Lee

Research Collection School Of Economics

Exclusion restrictions are routinely used in sample-selection models with selection and outcome equations. A false restriction, however, can cause an exclusion bias for the outcome equation estimator. In this paper, the specific form of the exclusion bias is derived for various sample-selection model estimators. Furthermore, it is shown that the outcome equation parameters for regressors with zero coefficients in the selection equation are immune to exclusion bias if only one regressor is excluded. Exclusion bias, or a lack thereof, is verified through a simulation study with the regressors taken from Mroz (1987). JEL Classification Numbers: C24, C34. [ABSTRACT FROM AUTHOR]

The Elasticity Of Substitution And Endogenous Growth, Hing-Man Leung Jan 2003

The Elasticity Of Substitution And Endogenous Growth, Hing-Man Leung

Research Collection School Of Economics

The endogenous growth literature focuses exclusively on Cobb-Douglas. Elasticities other than unity are ignored. A recent paper by Klump and Grandville (2000) examined other elasticities but assumed an exogenous saving rate. By contrast, this paper studies elasticity and endogenous growth. Endogeneity is important since elasticity preserves capital’s productivity and encourages saving. Two models are presented. The first assumes exogenous technological change. We find elasticity to have a positive level effect on income. No rate of growth effect is found. The second model allows learning by doing from capital accumulation. In addition to the level effect, rate of growth effects are …

Incentive Compatibility In Multi-Unit Auctions, Sushil Bikhchandani, Shurojit Chatterji, Arunava Sen Jan 2003

Incentive Compatibility In Multi-Unit Auctions, Sushil Bikhchandani, Shurojit Chatterji, Arunava Sen

Research Collection School Of Economics

We characterize incentive compatibility in multi-unit auctions with multi-dimensional types. An allocation mechanism is incentive compatible if and only if it is nondecreasing in marginal utilities (NDMU). The notion of incentive compatibility we adopt is dominant strategy in private value models and ex post incentive compatibility in models with interdependent values. NDMU is the following requirement: if changing one buyer’s type, while keeping everyone else’s types the same, changes this buyer’s allocation then the new allocation must be relatively more attractive (or relatively less unattractive) to this buyer. We also establish a price characterization of incentive compatible mechanisms.

Analyzing Erp Implementation At A Public University Using The Innovation Strategy Model, Keng Siau, J. Messersmith Jan 2003

Analyzing Erp Implementation At A Public University Using The Innovation Strategy Model, Keng Siau, J. Messersmith

Research Collection School Of Computing and Information Systems

Enterprise Resource Planning (ERP) systems have revolutionized the way companies are using information technology in their businesses. ERP was created in an effort to streamline business processes and has proven to be successful in many operations. Unfortunately, not all ERP implementations have met expectations. One way that businesses may be able to increase success rates is to embrace creativity and innovation in their ERP implementations. For businesses to do this, they must first understand how creativity originates and how that creativity can be integrated into business solutions. This article presents a case study that examines the ERP implementation at a …

Global Trends In Mediation, Nadja Alexander Jan 2003

Global Trends In Mediation, Nadja Alexander

Research Collection Yong Pung How School Of Law

Mediation is a process both new, in terms of its emergence in the legal arena, and old in terms of its timeless universality. From its birth in the western world, mediation has travelled a winding and often challenging path through common law and then civil law jurisdictions. Suggestions that mediation would be nothing more than a short-lived fad have been short-lived themselves. At the same time many critical questions about mediation process, mediation structures and environment, and mediation outcomes have yet to be explored from a global and comparative perspective.The civil law/ common law dichotomy has always been a fascination …

Performance Measurement Framework For Hierarchical Text Classification, Ee Peng Lim, Aixin Sun, Wee-Keong Ng Jan 2003

Performance Measurement Framework For Hierarchical Text Classification, Ee Peng Lim, Aixin Sun, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

Hierarchical text classification or simply hierarchical classification refers to assigning a document to one or more suitable categories from a hierarchical category space. In our literature survey, we have found that the existing hierarchical classification experiments used a variety of measures to evaluate performance. These performance measures often assume independence between categories and do not consider documents misclassified into categories that are similar or not far from the correct categories in the category tree. In this paper, we therefore propose new performance measures for hierarchical classification. The proposed performance measures consist of category similarity measures and distance-based measures that consider …

Validity And Obligation In Natural Law Theory, Seow Hon Tan Jan 2003

Validity And Obligation In Natural Law Theory, Seow Hon Tan

Research Collection Yong Pung How School Of Law

The relation between law and morality is a point of contention amongst legal philosophers. There are several issues: first, the extent to which law should incorporate moral standards; second, the effect of moral status on legal validity (the "validity question"); third, the effect of legal validity on the obligation created by the law (the "obedience question"). Because most positivists concede that it is desirable for law to accord with notions of justice and morals and that law often incorporates morals, the first issue features less prominently in the positivism-natural law debate. This article examines John Finnis's views on the latter …

A New Node Centroid Algorithm For Bandwidth Minimization, Brian Rodrigues, F. Xiao, A. Lim Jan 2003

A New Node Centroid Algorithm For Bandwidth Minimization, Brian Rodrigues, F. Xiao, A. Lim

Research Collection Lee Kong Chian School Of Business

We propose a Node Centroid method with Hill-Climbing to solve the well-known matrix band-width minimization problem, which is to permute rows and columns of the matrix to minimize its bandwidth. Many heuristics have been developed for this NP-complete problem including the Cuthill-McKee (CM) and the Gibbs, Poole and Stockmeyer (GPS) algorithms. Recently, heuristics such as Simulated Annealing, Tabu Search and GRASP have been used, where Tabu Search and the GRASP with Path Relinking have achieved significantly better solution quality than the CM and GPS algorithms. Experimentation shows that the Node Centroid method achieves the best solution quality when compared with …

The Use Of Rewards To Increase And Decrease Trust: Mediating Processes And Differential Effects, Donald L. Ferrin, Kurt T. Dirks Jan 2003

The Use Of Rewards To Increase And Decrease Trust: Mediating Processes And Differential Effects, Donald L. Ferrin, Kurt T. Dirks

Research Collection Lee Kong Chian School Of Business

Hypotheses asserting that reward structures - an omnipresent element of the work context - have a strong influence on interpersonal trust are tested, and the cognitive and behavioral routes through which the effects may occur are explored. Specifically, attribution theory is used to identify several core processes including social perception, self-perception, and attributional biases that may explain trust development. A 3 x 2 experimental design in a problem-solving task was used to examine the hypotheses. The results suggest that reward structures have a strong influence on trust, and that the effect is mediated by causal schemas, suspicion effects, and self-perception. …

Legal Issues Under Wto Rules On The Closer Economic Partnership Arrangement (Cepa) Between Mainland China And Hong Kong, Henry S. Gao Jan 2003

Legal Issues Under Wto Rules On The Closer Economic Partnership Arrangement (Cepa) Between Mainland China And Hong Kong, Henry S. Gao

Research Collection Yong Pung How School Of Law

On 29 June 2003, the Central Government of the People's Republic of China (the Mainland) and the Hong Kong Special Administrative Region (HKSAR) signed the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA). As the first Regional Trade Agreement (RTA) for both sides, the CEPA provides a model for China to use the arrangements allowed under the rules of the World Trade Organization (WTO) to further trade liberalisation and promote economic development. This is a commendable endeavour. However, due to the complexity of the relevant rules of the WTO, caution must be exercised in the formulation and implementation of …

The Integrated Networks Model: Explaining Resource Allocations In Networked Markets, Judy K. Frels, Tasadduq Shervani, Rajendra Kumar Srivastava Jan 2003

The Integrated Networks Model: Explaining Resource Allocations In Networked Markets, Judy K. Frels, Tasadduq Shervani, Rajendra Kumar Srivastava

Research Collection Lee Kong Chian School Of Business

The last decade has witnessed a shift from a focus on the value created by a single firm and product to an examination of the value created by networks of firms (or product ecosystems) in which assets are comingled with external entities. The authors examine these market-based assets in the context of network markets and propose an Integrated Networks model in which three types of networks—user, complements, and producer—add value or enhance the attractiveness of the associated focal product. The authors empirically test the proposed model by surveying information technology professionals on their resource allocation decisions regarding the Unix and …

Are All Rivals Affected Equally By Bond Rating Downgrades?, Gary L. Caton, Jeremy Goh Jan 2003

Are All Rivals Affected Equally By Bond Rating Downgrades?, Gary L. Caton, Jeremy Goh

Research Collection Lee Kong Chian School Of Business

We use revisions in analysts' earnings forecasts to examine how the bad news associated with a bond rating downgrade gets transferred from the downgraded company to its rivals. In general, we find that stock analysts revise their earnings expectations downward for rivals of companies with downgraded debt. However, the significance of the revision is limited to rivals of downgraded companies with non-investment grade debt only. For the rivals of companies with investment grade debt, we find no significant forecast revisions. We hypothesize that this differential impact is due to differing levels of market visibility. This is consistent with our finding …

The Effect Of Taxes On The Pricing Of Defaultable Debt, Kian Guan Lim, Fenghua Song, Mitchell Craig Warachka Jan 2003

The Effect Of Taxes On The Pricing Of Defaultable Debt, Kian Guan Lim, Fenghua Song, Mitchell Craig Warachka

Research Collection Lee Kong Chian School Of Business

Empirical studies have documented the dependence of corporate credit spreads on default risk, equity premiums, and taxes. However, taxes have previously not been incorporated into reduced-form credit risk models. Therefore, we first extend the existing literature by considering a default intensity that depends on taxes as well as the default-free short rate and a market index. Consequently, we establish a theoretical basis to explain previous empirical findings regarding the significant impact of taxation on defaultable bond prices. Unlike previous models, tax implications for defaultable debt cannot be constructed from a sum of tax effects on zero coupon bonds. Our empirical …
