The Implications Of Technology Networks On Diffusion And Economic Growth, Hing-Man Leung Jul 2002

The Implications Of Technology Networks On Diffusion And Economic Growth, Hing-Man Leung

Research Collection School Of Economics

After the record-breaking run of high-speed growth in the United States during the late 1990s, a pressing question is Has anything fundamental changed in our growth engine? This paper examines an IT-led endogenous growth model driven by technology diffusion. Diffusion is in turn driven by network effect embodied in new technologies. The equilibrium long-term growth rate is however found to be independent of such technology networks. A novelty in our model is that innovation is discontinuous and it is separated by periods of diffusion. This (IT) network-diffusion is shown to be Sigmoid, and diffusion speed is slower than socially optimal.

Leadership Antecedents Of Informal Knowledge Acquisition And Dissemination, Siu Loon Hoe, Steve Mcshane Jul 2002

Leadership Antecedents Of Informal Knowledge Acquisition And Dissemination, Siu Loon Hoe, Steve Mcshane

Research Collection School Of Computing and Information Systems

Knowledge management is emerging as one of the leading influences on an organisation’s survival and competitive advantage (Blumentritt & Johnston 1999). Knowledge management is concerned with the effective acquisition, sharing, storage and utilisation of knowledge (Huber 1991; Saffady 1998). Corporate leaders are increasingly aware of the notion that an organisation’s long-term survival depends on its ability to generate new knowledge and continuously learn from the environment. The importance of a superior organisational learning capability as a source of competitive advantage is a common refrain among both managers and scholars (e.g. Kohli & Jaworski 1990; Nonaka 1991; Quinn 1992; Slater & …

Structural Change And Lead-Lag Relationship Between The Nikkei Spot Index And Futures Price: A Genetic Programming Approach, Donald Lien, Yiu Kuen Tse, X. B. Chang Jun 2002

Structural Change And Lead-Lag Relationship Between The Nikkei Spot Index And Futures Price: A Genetic Programming Approach, Donald Lien, Yiu Kuen Tse, X. B. Chang

Research Collection School of Economics

In this paper we adopt a nonparametric genetic programming approach to identify the structural changes in the Nikkei spot index and futures price. Due to the dominance of the “normal” period in sample size, the lead-lag relationship identified in the spot-futures system based on conventional methods such as test for Granger causality pertains to the normal period and may not be applicable in the “extreme” period. Using genetic programming we identify the lead-lag relationship based on the chronological ordering of the structural changes in the spot and futures markets. Our results show that in recent periods, major market changes originated …

Strategic Development Of Airport And Rail Infrastructure: The Case Of Singapore, Sock-Yong Phang Jun 2002

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.

How Should We Interpret Evidence Of Time Varying Conditional Skewness?, Gamini Premaratne, Anthony S. Tay Jun 2002

How Should We Interpret Evidence Of Time Varying Conditional Skewness?, Gamini Premaratne, Anthony S. Tay

Research Collection School Of Economics

Several recent articles report evidence of predictability in the skewness of equity returns, raising hopes that predictability in third moments will be useful for forecasting the probability of tail events. The evidence is unfortunately difficult to interpret, partly because they were obtained mainly from parametric models of time-varying conditional skewness, and because little is known about the behavior of such models, for instance, when there are outliers. We investigate a non-parametric approach to testing for predictability in skewness. Specifically, we explore the size and power of a Runs tests, and compare this approach with other tests. A re-examination of daily …

The Necessities And Luxuries Of Mate Preferences: Testing The Tradeoffs, Norman P. Li, J. Michael Bailey, Douglas T. Kenrick, Joan A. W. Linsenmeier Jun 2002

The Necessities And Luxuries Of Mate Preferences: Testing The Tradeoffs, Norman P. Li, J. Michael Bailey, Douglas T. Kenrick, Joan A. W. Linsenmeier

Research Collection School of Social Sciences

Social exchange and evolutionary models of mate selection incorporate economic assumptions but have not considered a key distinction between necessities and luxuries. This distinction can clarify an apparent paradox: Status and attractiveness, though emphasized by many researchers, are not typically rated highly by research participants. Three studies supported the hypothesis that women and men first ensure sufficient levels of necessities in potential mates before considering many other characteristics rated as more important in prior surveys. In Studies 1 and 2, participants designed ideal long-term mates, purchasing various characteristics with 3 different budgets. Study 3 used a mate-screening paradigm and showed …

Growth And Volatility, Hing-Man Leung Jun 2002

Growth And Volatility, Hing-Man Leung

Research Collection School Of Economics

This paper has two objectives. First, to establish empirically a U-shaped relation between GDP growth rate and income volatility. The backward as well as the fast-growing countries have had extensive volatility; but developed nations by contrast have enjoyed much more stable income. Second, to present a macroeconomic model to study how growth and volatility evolve together. The twin endogenous variables are financial liberalization interacting with liquidity constraints. Opening LDC financial markets could raise or lower their long-term income and growth rates, depending on the severity of existing liquidity constraints. Financial liberalization and removing financial market imperfections unambiguously worsen income volatility.

Equality And Diversity, Chandran Kukathas Jun 2002

Equality And Diversity, Chandran Kukathas

Research Collection School of Social Sciences

The foundations of human inequality lie in the fact of human diversity, or in the human tendency to differentiate from some while associating with others to form groups. The diversity which results from association and differentiation makes equality unattainable. Diversity and equality are incompatible, and attempts to promote one can only be made at the expense of the other. In these circumstances, we should abandon the ideal of equality as incapable of offering us an adequate understanding of the nature of the good society.

Client Perspectives Of Multicultural Counselling Competence: A Qualitative Examination, Donald B. Pope-Davis, Rebecca L. Toporek, Lideth Ortega-Villalobos, Daniela P. Ligiero, Christopher S. Brittan-Powell, William Liu, Michael R. Bashshur, Jamila N. Codrington, Christopher T. H. Liang May 2002

Client Perspectives Of Multicultural Counselling Competence: A Qualitative Examination, Donald B. Pope-Davis, Rebecca L. Toporek, Lideth Ortega-Villalobos, Daniela P. Ligiero, Christopher S. Brittan-Powell, William Liu, Michael R. Bashshur, Jamila N. Codrington, Christopher T. H. Liang

Research Collection Lee Kong Chian School Of Business

Multicultural competence is a burgeoning area of research in counseling psychology. However, there has been little focus on understanding multicultural competence from the perspective of clients. This study used qualitative interviews and grounded theory to develop a model of clients’ perspectives of multicultural counseling. The resulting model suggested that clients’ experiences of multicultural counseling were contingent on their self-identified needs and on how well they felt the counselor met these needs. Moreover, clients appeared to actively manage and moderate the extent to which culture was broached in counseling based on a host of conditions including counseling relationship, salience of identity, …

Investing In Hedge Funds: Risks, Returns And Pitfalls, Dong Hong, David Kuo Chuen Lee, Kok Fai Phoon May 2002

Investing In Hedge Funds: Risks, Returns And Pitfalls, Dong Hong, David Kuo Chuen Lee, Kok Fai Phoon

Research Collection Lee Kong Chian School Of Business

Hedge funds are collective investment vehicles fast becoming popular with high net worth individuals as well as institutional investors. These are funds that are often established with a special legal status that allows their investment managers a free hand to use derivatives, short sell, and exploit leverage to raise returns and cushion risk. Given that that they have substantial latitude to invest, it is instructive to examine the performance of hedge funds compared to other forms of managed funds. This paper provides an overview of hedge funds and discusses their empirical risk and return profiles. It also poses some concerns …

Is Public Space Suited To Co-Operative Inquiry?, Sor-Hoon Tan May 2002

Is Public Space Suited To Co-Operative Inquiry?, Sor-Hoon Tan

Research Collection School of Social Sciences

This article questions the nature of the philosophical commitment to the problem of 'the public' in modernity. To what extent does the natural form of the public determine the use and value of the instruments of pragmatism in the public-private divide. In this interpretation, John Dewey's ideas about 'the public' are presented in terms of how to solve a specific problem through what he sees as 'co-operative inquiry'. The article also examines the role of public space in the process of democratization through the potential of co-operative inquiry. More often than not, it appears that the politics of public space …

Potential For Floating Offshore Wind Energy In Japanese Waters, A. R. Henderson, R. Leutz, Tomoki Fujii May 2002

Potential For Floating Offshore Wind Energy In Japanese Waters, A. R. Henderson, R. Leutz, Tomoki Fujii

Research Collection School Of Economics

The prospects for large scale commercialisation of sea-bed-mounted offshore windfarms are currently excellent, with the existing small-scale prototype windfarms currently being joined by the first large-scale parks in the shallow seas off the Danish, German, Swedish, Dutch, Belgian, British and Irish coasts. However other countries, including Japan, have much more limited regions of the shallow waters suitable for such developments and hence other concepts will also need to be utilised if offshore wind energy is also to become a major source of energy there.

Markov Chains In Predictive Models Of Currency Crises - With Applications To Southeast Asia, Roberto S. Mariano, Abdul G. Abiad, Gultekin Bulent, Tayyeb Shabbir, Augustine H. H. Tan May 2002

Markov Chains In Predictive Models Of Currency Crises - With Applications To Southeast Asia, Roberto S. Mariano, Abdul G. Abiad, Gultekin Bulent, Tayyeb Shabbir, Augustine H. H. Tan

Research Collection School Of Economics

The decade of the 1990s was marked by an unusual number of financial and economic crises such as the attack on the European Monetary System in 1992-93, the Mexican peso crisis in 1994-95, the Asian crisis in 1997, the Russian default in 1998 and its spillover to Latin America. The Turkish currency and banking crisis in 2001 and the recent difficulties in Argentina indicate that financial crises are still part of the current economic events. In the wake of such developments, there has been a resurgence of interest in early warning systems that can anticipate the likely occurrence of such …

A Class Of Nonlinear Stochastic Volatility Models, Jun Yu, Zhenlin Yang Apr 2002

A Class Of Nonlinear Stochastic Volatility Models, Jun Yu, Zhenlin Yang

Research Collection School Of Economics

This paper proposes a class of nonlinear stochastic volatility models based on the Box-Cox transformation which offers an alternative to the one introduced in Andersen (1994). The proposed class encompasses many parametric stochastic volatility models that have appeared in the literature, including the well known lognormal stochastic volatility model, and has an advantage in the ease with which different specifications on stochastic volatility can be tested. In addition, the functional form of transformation which induces marginal normality of volatility is obtained as a byproduct of this general way of modeling stochastic volatility. The efficient method of moments approach is used …

A New Coincident Index Of Business Cycles Based On Monthly And Quarterly Series, Roberto S. Mariano, Yasutomo Murasawa Apr 2002

A New Coincident Index Of Business Cycles Based On Monthly And Quarterly Series, Roberto S. Mariano, Yasutomo Murasawa

Research Collection School Of Economics

Popular monthly coincident indices of business cycles, e.g. the composite index and the Stock-Watson coincident index, have two shortcomings. First, they ignore information contained in quarterly indicator such as real GPD. Second, they lack economic interpretation; hence the heights of peaks and the depths of troughs depend on the choice of an index. This paper extends the Stock-Watson coincident index by applying maximum likelihood factor analysis to a mixed-frequency series of quarterly real GDP and monthly coincident business cycle indicators. The resulting index is related to latent monthly real GDP.

Endogenous Growth And The Manufacturing Revolution, Hing-Man Leung Mar 2002

Endogenous Growth And The Manufacturing Revolution, Hing-Man Leung

Research Collection School Of Economics

Manufacturing is undergoing a revolution. Teamwork, job-rotation, multitasking are superseding the Taylorist mode of organization. The skilled workforce, armed with automated machines, is gradually substituting and replacing the unskilled. At the same time the U.S. economy is experiencing record breaking growth. Is faster growth a consequence of this manufacturing revolution? We study this by inserting dynamic career choice into endogenous growth by human capital accumulation. The answer is affirmative: The gradual substitution of the unskilled by the skilled boosts the long-term growth trend. The model also explains worsening wage inequality between as well as within the skilled groups.

Less Developed Country Business Cycles, Hing-Man Leung Mar 2002

Less Developed Country Business Cycles, Hing-Man Leung

Research Collection School Of Economics

Less developed countries (LDCs) have experienced considerable business cycles in recent decades. This coincides with significant increases in their external debt to GDP ratios. Recent theoretical credit cycles literature suggests that indebtedness, and the resulting liquidity constraints, could explain LDC business cycles. This paper builds a macroeconomic model to trace the LDC income paths. In this model indebtedness and liquidity constraints reduce aggregate investment. We use the World Data (1995) to calibrate for the convergence parameter. It is found that LDC cycles are convergent and non-oscillatory, and indebtedness delays the return to long-term steady state income.

Networked Growth, Hing-Man Leung Mar 2002

Networked Growth, Hing-Man Leung

Research Collection School Of Economics

This paper searches for a new growth engine in the new Info-Tech economy. IT-network effects are incorporated into Romer’s (1990) framework. Network effects support long-term steady state growth in per capita variables even without innovation, and growth rate increases with network externalities. Networked growth is sub-optimal, so should we break up an IT monopoly? To answer this we compare monopoly, Cournot and Bertrand set-ups. Cournot always ranks last socially, but Bertrand can be superior to monopoly if network effects are strong. When network interacts with Romer’s endogenous innovation, growth rate increases, probably by up to a percentage point per year.

The Endogeneity Problem In Electoral Studies: A Critical Re-Examination Of Duverger's Mechanical Effect, Kenneth Benoit Mar 2002

The Endogeneity Problem In Electoral Studies: A Critical Re-Examination Of Duverger's Mechanical Effect, Kenneth Benoit

Research Collection School of Social Sciences

Studies of electoral law consequences typically treat electoral laws as exogenous factors affecting political party systems, even while acknowledging that political parties often tailor electoral institutions to suit their own distributional needs. This study represents a departure from that approach, directly examining one aspect of the endogeneity of electoral systems: the endogeneity of Duverger's ‘mechanical’ effect. Theory clearly posits that the Duvergerian ‘psychological’ effect of electoral rules occurs in anticipation of their reductive mechanical effect, yet in empirical models this endogenous character is typically ignored. In this paper I formalize the two types of Duvergerian effects of electoral laws in …

Isotonic Designs For Phase I Trials, Denis H. Y. Leung, You-Gan Wang Feb 2002

Isotonic Designs For Phase I Trials, Denis H. Y. Leung, You-Gan Wang

Research Collection School Of Economics

The purpose of a phase I trial in cancer is to determine the level (dose) of the treatment under study that has an acceptable level of adverse effects. Although substantial progress has recently been made in this area using parametric approaches, the method that is widely used is based on treating small cohorts of patients at escalating doses until the frequency of toxicities seen at a dose exceeds a predefined tolerable toxicity rate. This method is popular because of its simplicity and freedom from parametric assumptions. In this paper, we consider cases in which it is undesirable to assume a …

The American People In Crisis: A Content Analysis, Roderick P. Hart, Sharon E. Jarvis, Elvin T. Lim Feb 2002

The American People In Crisis: A Content Analysis, Roderick P. Hart, Sharon E. Jarvis, Elvin T. Lim

Research Collection School of Social Sciences

This study examines how images of the American electorate were deployed after the11 September 2001 terrorism incident and during the Clinton impeachment. Transcripts of congressional proceedings, news coverage, and presidential campaign addresses were analyzed to determine how the phrase the American people was used during these two crises and in unrelated presidential campaign speeches. The analysis considered the roles, actions, qualities, and circumstances ascribed to the people, as well as the time orientation and the forces aligned against the people. The results show that (1) relative to presidential campaign rhetoric, both crises resulted in greater concentration on the electorate; (2) …

Endogenous Growth And Equilibrium Unemployment In A North-South Model Of The World Economy, Hian Teck Hoon Feb 2002

Endogenous Growth And Equilibrium Unemployment In A North-South Model Of The World Economy, Hian Teck Hoon

Research Collection School Of Economics

A North-South model is developed which incorporates an endogenous rate of equilibrium unemployment in the North in the context of long-run growth. It is shown how increases in the size of public debt and unemployment compensation financed by payroll taxation, all measured relative to productivity, raise the Northern natural rate of unemployment and, consequently, reduce the global rate of long-run growth. The effect of the shocks is also to drive down the rate of employment expansion in the South. A set of the fundamental determinants of the world terms of trade is obtained, which includes policy parameters.

Five Trends In Presidential Rhetoric: An Analysis Of Rhetoric From George Washington To Bill Clinton, Elvin T. Lim Feb 2002

Five Trends In Presidential Rhetoric: An Analysis Of Rhetoric From George Washington To Bill Clinton, Elvin T. Lim

Research Collection School of Social Sciences

Several political scientists have argued that the presidential recourse to public rhetoric as a mode of political influence in the twentieth century represents a significant departure from a pre-twentieth-century institutional norm where “going public” was both rare and frowned upon. This article looks specifically at the changes in the substance of rhetoric that have accompanied this alleged institutional transformation. Applying computer-assisted content analysis to all the inaugural addresses and annual messages delivered between 1789 and 2000, the author identifies and explores five significant changes in twentieth-century presidential rhetoric that would qualifiedly support the thesis of institutional transformation in its rhetorical …

French Military Policies In The Aftermath Of The Yên Bay Mutiny, 1930: Old Security Dilemmas Return To The Surface, Tobias Frederik Rettig Jan 2002

French Military Policies In The Aftermath Of The Yên Bay Mutiny, 1930: Old Security Dilemmas Return To The Surface, Tobias Frederik Rettig

Research Collection School of Social Sciences

This paper provides a brief summary of the Yên Bay mutiny of 10 February 1930, before examining its links to a wider insurrectionary attempt by the Vietnamese Nationalist Party in parts of Tonkin and the reasons why the attempted insurrection was to begin at Yên Bay but not in other garrison towns. It then places the mutiny in a context in which the use of Vietnamese soldiers in French service was necessary in order to maintain French supremacy as a colonial and protectorate power in French Indo-China. But instead of focusing on the mutiny itself and its causes, the main …

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.
