Tests Of Transformation In Nonlinear Regression, Zhenlin Yang, Gemai Chen Sep 2004

Tests Of Transformation In Nonlinear Regression, Zhenlin Yang, Gemai Chen

Research Collection School Of Economics

This paper presents three versions of the Lagrange multiplier (LM) tests of transformation in nonlinear regression: (i) LM test based on expected information, (ii) LM test based on Hessian, and (iii) the LM test based on gradient. All three tests can be easily implemented through a nonlinear least squares procedure. Simulation results show that, in terms of finite sample performance, the LM test based on expected information is the best, followed by the LM test based on Hessian and then the LM test based on gradient. The LM test based on gradient can perform rather poorly. An example is given …

The Making Of An Innovator, Hian Teck Hoon Sep 2004

The Making Of An Innovator, Hian Teck Hoon

Research Collection School Of Economics

Innovators experiment with things to come up with new ideas to improve the quality of existing products, develop differentiated or new products and re-organise business processes to lower costs. In a big corporation, there might be a whole R&D department where innovators are employed to design new blueprints so the company can constantly make new offerings. But innovators can also be found in small enterprises tinkering with recipes, for example, to win new customers. Innovators no doubt derive pleasure from their creative work. Yet, in modern economies, they must be employed in a firm that successfully translates their innovative activity …

Future Fiscal And Budgetary Shocks, Hian Teck Hoon, Edmund S. Phelps Sep 2004

Future Fiscal And Budgetary Shocks, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

We study here the effects of future tax and budgetary shocks on present levels of economic activity and real interest rates in a nonmonetary and possibly non-Ricardian economy. The paper first takes up an (unanticipated) temporary tax cut to be effective on a given future date—a delayed debt bomb. The sudden prospect of this future-dated shock causes at once a drop in the (unit) value placed on the firms’ business asset, the customer, and accordingly on the price of shares—with the result that the hourly wage, hours worked and GDP drop in tandem. This paradox of reduced activity through announcement …

Is The Good Life The Easy Life?, Christie N. Scollon, Laura A. King Sep 2004

Is The Good Life The Easy Life?, Christie N. Scollon, Laura A. King

Research Collection School of Social Sciences

Three studies examined folk concepts of the good life. Participants rated the desirability and moral goodness of a life as a function of the happiness, meaning, and effort experienced. Happiness and meaning were solid predictors of the good life, replicating King and Napa (1998). Study 1 (N = 381) included wealth as an additional factor. Results showed little desire for exorbitant (over moderate) wealth, but also a desire to avoid poverty. When effort was operationalized as number of hours worked, respondents desired the easy life, particularly at moderate levels of income. When effort was operationalized as effortful engagement (Study 2), …

Models Of Electoral System Change, Kenneth Benoit Sep 2004

Models Of Electoral System Change, Kenneth Benoit

Research Collection School of Social Sciences

Electoral systems are commonly treated as exogenous determinants of political party systems, yet our theoretical understanding remains limited as to how these institutions themselves are determined. Part of the problem lies with the subject matter itself: electoral system change is frequently idiosyncratic, often occurring during episodes of exceptional political change. Yet another aspect of the problem is that explanations of electoral system change frequently occur piecemeal in application to specific cases, without systematic or comparative development. Addressing both problems, I first survey the existing literature to develop a comprehensive typology of explanations of electoral system change and persistence. I then …

The Antecedents Of Value Creation In Singapore Corporation, Wee Liang Tan, Teck Meng Tan Sep 2004

The Antecedents Of Value Creation In Singapore Corporation, Wee Liang Tan, Teck Meng Tan

Research Collection Lee Kong Chian School Of Business

The impetus for value creation has led to greater interest in encouraging entrepreneurship within organizations (intrapreneurship). The intrapreneurship literature reveals general agreement that organizational entrepreneurship flourishes where the environmental conditions of an organization are most favorable. However, there is little empirical research examining the relationship of the organizational climate and the intentions of employees to be intrapreneurs, and their actual participation in such activities. This paper reports a study on the elements of organizational climate on intrapreneurship attitudes, intentions and actions on the part of middle managers in corporations in Singapore.

The Politics Of Wto Enforcement Mechanism, Pao Li Chang Aug 2004

The Politics Of Wto Enforcement Mechanism, Pao Li Chang

Research Collection School Of Economics

This paper attempts to develop a formal economic framework to analyze the influences of domestic political considerations by democratic governments in shaping the WTO enforcement outcomes following a violation ruling against the defendant. Since a different mix of import and export sectors in the defendant and complainant country will benefit from the various potential enforcement outcomes, they become competing forces which steer the strategic interactions between the disputing governments. The results of the paper illustrate the complainant's strategy in selecting the retaliation list, and the likelihood of the defendant's compliance or compensation in response to the proposed or foreseeable retaliation, …

The Optimal Design Of Fallible Organizations: Invariance Of Optimal Decision Criterion And Uniqueness Of Hierarchy And Polyarchy Structures, Winston T. H. Koh Aug 2004

The Optimal Design Of Fallible Organizations: Invariance Of Optimal Decision Criterion And Uniqueness Of Hierarchy And Polyarchy Structures, Winston T. H. Koh

Research Collection School Of Economics

We present a general framework to study the project selection problem in an organization of fallible decision-makers. We show that when the organizational size and the majority rule for project acceptance are optimized simultaneously, the optimal quality of decision-making, as determined by the decision criterion, is invariant, and depends only on the expertise of decision-makers. This result clarifies that the circumstances under which the decision-making quality varies with the organizational structure are situations where the organizational size or majority rule is restricted from reaching the optimal level. Moreover, in contrast to earlier findings in the literature that the hierarchy and …

Board Structure, Political Influence And Firm Performance - An Empirical Study On Publicly Listed Firms In China, Dongping Han, Fusheng Wang, Heng Yue Aug 2004

Board Structure, Political Influence And Firm Performance - An Empirical Study On Publicly Listed Firms In China, Dongping Han, Fusheng Wang, Heng Yue

Research Collection School Of Accountancy

The board of directors is the cornerstone of any effective corporate governance system. A well-structured board can effectively monitor and motivate management of a company for the benefit of the company's shareholders. This paper investigates the relationship between board structure and firm performance using a sample of 490 publicly listed firms in China. The characteristics of board structure we examined include: board size, inside/outside/independent directors, CEO/Chair duality, stock holdings of directors, the rewards to directors and aged directors. We find significant relationship between firm performance and three characteristics: the rewards to director, the stock holdings of directors and the existence …

Transport Logistics Planning With Service-Level Constraints, Hoong Chuin Lau, K. M. Ng, Xintao Wu Jul 2004

Transport Logistics Planning With Service-Level Constraints, Hoong Chuin Lau, K. M. Ng, Xintao Wu

Research Collection School Of Computing and Information Systems

In this paper, we study a logistics problem arising in military transport planning. A military organization operates a large fleet of vehicles in a depot to serve the requests of various operational units. Each request has a fixed start and end time, and is served by a prescribed number of vehicles. We address the following two problems: (1) how many vehicles are at least needed to meet a given service level of requests; and (2) suppose we allow each request to shift its start time by a constant duration, call all the requests be met? A Niche genetic algorithm, together …

The Eu And The Npt: Testing The New European Nonproliferation Strategy, Clara Portela Jul 2004

The Eu And The Npt: Testing The New European Nonproliferation Strategy, Clara Portela

Research Collection School of Social Sciences

Only a few years ago, the idea that the European Union (EU) could become a significant actor in the nuclear nonproliferation regime would have met with great scepticism. An organisation comprising nuclear weapon states (NWS) along with non-nuclear weapons states (NNWS) - some of who are disarmament-minded - would have been considered incapable of framing any common response to nuclear proliferation. And yet, today we find that the EU is establishing itself as an actor in the field of nonproliferation of weapons of mass destruction (WMD), and that it has even developed a Strategy to guide its endeavours.This article will …

The Impact Of Culture On Accounting Choices: Can Cultural Conservatism Explain Accounting Conservatism?, Tony Kang, Lian Fen Lee, Jeffrey Ng, Joanne Tay Jul 2004

The Impact Of Culture On Accounting Choices: Can Cultural Conservatism Explain Accounting Conservatism?, Tony Kang, Lian Fen Lee, Jeffrey Ng, Joanne Tay

Research Collection School Of Accountancy

We explore the extent to which cultural conservatism explains accounting conservatism. Our primary measure for accounting conservatism is the magnitude of non-operating accruals, which are highly discretionary in nature. Culture permeates values and attitudes, and thus governs many aspects of human behavior. Hence it is likely to affect managers’ accounting choice behaviors. However, there is surprisingly little evidence on the association between the two types of conservatism in the literature. Using a sample of 800 firms originating from 21 countries during the nine-year period from 1993 to 2001, we find strong evidence that the managers in more conservative cultural environments …

Estimation Of Hyperbolic Diffusion Using Markov Chain Monte Carlo Method, Yiu Kuen Tse, Xibin Zhang, Jun Yu Jul 2004

Estimation Of Hyperbolic Diffusion Using Markov Chain Monte Carlo Method, Yiu Kuen Tse, Xibin Zhang, Jun Yu

Research Collection School Of Economics

In this paper we propose a Bayesian method to estimate the hyperbolic diffusion model. The approach is based on the Markov chain Monte Carlo (MCMC) method with the likelihood of the discretized process as the approximate posterior likelihood. We demonstrate that the MCMC method Provides a useful tool in analysing hyperbolic diffusions. In particular, quantities of posterior distributions obtained from the MCMC outputs can be used for statistical inference. The MCMC method based on the Milstein scheme is unsatisfactory. Our simulation study shows that the hyperbolic diffusion exhibits many of the stylized facts about asset returns documented in the discrete-time …

Singapore's Foray Into Bangalore, India: An Empirical Review, Amrit Vaidyanath, Caroline Yeoh, Siang Yeung Wong Jul 2004

Singapore's Foray Into Bangalore, India: An Empirical Review, Amrit Vaidyanath, Caroline Yeoh, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

Singapore’s regionalization stratagem led to the establishment of industrial parks in China, India and several South-East Asian countries. The strategic intent behind these overseas projects was two-fold: exporting Singapore’s competencies such as management know-how, technological capabilities and corrupt-free administration to regions where such positive factors were lacking and secondly, exploiting comparative advantages that each region had to offer. This paper investigates Singapore’s foray into India, through the technology park in Bangalore. It evaluates the location specific benefits of the site, primarily in terms of abundant and low-cost labor resources. Accompanied by empirical findings, this study finds that, while location-specific merits …

Exporting Expertise: A Note On Singapore's Gambit In Bangalore, India, Caroline Yeoh, Amrit Vaidyanath, Siang Yeung Wong Jul 2004

Exporting Expertise: A Note On Singapore's Gambit In Bangalore, India, Caroline Yeoh, Amrit Vaidyanath, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

Infrastructure can be unreliable and administration subject to corruption in Asia’s rapidly emerging economies. This context presented Singapore with unique opportunities to export its ‘positive reputation’ to locations where these attributes are less certain, through the provision of superior infrastructure, the ability to negotiate investment concessions and, where existing, through the links to influential business groups in the investment location. This strategic initiative is premised on the perception that Singapore’s good relations with multinationals, as well as “connections” with Asian business networks, will give the industrial-township projects a marketing advantage. To complement the extensive literature on Singapore’s flagship projects in …

Forecasting The Global Electronics Cycle With Leading Indicators: A Var Approach, Hwee Kwan Chow Jul 2004

Forecasting The Global Electronics Cycle With Leading Indicators: A Var Approach, Hwee Kwan Chow

Research Collection School Of Economics

Developments in the global electronics industry are typically monitored by tracking indicators that span a whole spectrum of activities in the sector. However, these indicators invariably give mixed signals at each point in time, thereby hampering efforts at prediction. In this paper, we propose a unified framework for forecasting the global electronics cycle by constructing a VAR model that captures the economic interactions between leading indicators representing expectations, orders, inventories and prices. The ability of the indicators to presage world semiconductor sales is first demonstrated by Granger causality tests. The VAR model is then used to derive the dynamic paths …

Monotonicity Conditions And Inequality Imputation For Sample-Selection And Non-Response Problems, Myoung-Jae Lee Jul 2004

Monotonicity Conditions And Inequality Imputation For Sample-Selection And Non-Response Problems, Myoung-Jae Lee

Research Collection School Of Economics

Under a sample selection or non-response problem, where a response variable y is observed only when a condition δ = 1 is met, the identified mean E(y|δ = 1) is not equal to the desired mean E(y). But the monotonicity condition E(y|δ = 1) ≤ E(y|δ = 0) yields an informative bound E(y|δ = 1) ≤ E(y), which is enough for certain inferences. For example, in a majority voting with δ being the vote-turnout, it is enough to know if E(y) > 0.5 or not, for which E(y|δ = 1) > 0.5 is sufficient under the monotonicity. The main question is then …

Embedded Co-Operation In The Context Of Singapore's Investment Enclaves In Indonesia And Vietnam: A Strategy Reconsidered, Caroline Yeoh, Siang Yeung Wong Jul 2004

Embedded Co-Operation In The Context Of Singapore's Investment Enclaves In Indonesia And Vietnam: A Strategy Reconsidered, Caroline Yeoh, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

Regional industrial development projects - development packages assembled, administered and promoted by consortia of sovereign national governments - are new players in the global competition for foreign investments. Singapore's flagship projects in China have received much attention. Our paper reports on Singapore's lesser-known projects in Indonesia and Vietnam. The strategic intent of these transborder industrialization initiatives is to set in place a configuration for the city-state to restructure its domestic industries, and yet retain important linkages with production centers in low-cost environments. The effectiveness of this stratagem is evaluated from the perspectives of the tenant firms, as well as from …

Expectations Formation And Forecasting Of Vehicle Demand: An Empirical Study Of The Vehicle Quota Auctions In Singapore, Sing-Fat Chu, Winston T. H. Koh, Yiu Kuen Tse Jun 2004

Expectations Formation And Forecasting Of Vehicle Demand: An Empirical Study Of The Vehicle Quota Auctions In Singapore, Sing-Fat Chu, Winston T. H. Koh, Yiu Kuen Tse

Research Collection School Of Economics

This paper studies expectations formation and forecasting of vehicle demand in Singapore under the vehicle quota system. Under the system, a car buyer must first bid for a vehicle license in monthly auctions in order to purchase a new car. We construct an econometric model to test the hypothesis that past bid distributions of the license auctions contain information that car buyers can use to update their expectations about the intensity of market demand, forecast license premiums and formulate their bidding strategies in future auctions. Our empirical analysis indicates that past bid distributions have a good degree of predictive power …

On Leverage In A Stochastic Volatility Model, Jun Yu Jun 2004

On Leverage In A Stochastic Volatility Model, Jun Yu

Research Collection School Of Economics

This paper is concerned with specification for modelling financial leverage effect in the context of stochastic volatility (SV) models. Two alternative specifications co-exist in the literature. One is the Euler approximation to the well known continuous time SV model with leverage effect and the other is the discrete time SV model of Jacquier, Polson and Rossi (2004, Journal of Econometrics, forthcoming). Using a Gaussian nonlinear state space form with uncorrelated measurement and transition errors, I show that it is easy to interpret the leverage effect in the conventional model whereas it is not clear how to obtain the leverage effect …

Multiple Testing To Establish Superiority/Equivalence Of A New Treatment Compared With K Standard Treatments For Unbalanced Designs, Koon Shing Kwong, Siu Hung Cheung, Wai-Sum Chan Jun 2004

Multiple Testing To Establish Superiority/Equivalence Of A New Treatment Compared With K Standard Treatments For Unbalanced Designs, Koon Shing Kwong, Siu Hung Cheung, Wai-Sum Chan

Research Collection School Of Economics

In clinical studies, multiple superiority/equivalence testing procedures can be applied to classify a new treatment as superior, equivalent (same therapeutic effect), or inferior to each set of standard treatments. Previous stepwise approaches (Dunnett and Tamhane, 1997, Statistics in Medicine 16, 2489–2506; Kwong, 2001, Journal of Statistical Planning and Inference 97, 359–366) are only appropriate for balanced designs. Unfortunately, the construction of similar tests for unbalanced designs is far more complex, with two major difficulties: (i) the ordering of test statistics for superiority may not be the same as the ordering of test statistics for equivalence; and (ii) the correlation structure …

The Case For Clumsiness, Michael Thompson, Marco Verweij Jun 2004

The Case For Clumsiness, Michael Thompson, Marco Verweij

Research Collection School of Social Sciences

Most climatologists agree that by burning fossil fuels and engaging in other forms of consumption and production we are increasing the amount of greenhouse gases that float around in the atmosphere. These gases, in trapping some of the sun’s heat, warm the earth and enable life. The trouble is, some predict, that if we continue to accumulate those gases, over the course of the new century the average temperature on earth will rise and local climates will change, with possibly catastrophic consequences. Will this indeed happen? If so, should we do something about it? And if yes, what and when? …

The Singapore "Advantage" In India: A Perception Or A Premium?, Alexandra Si-Lan Wee, Ai Lin Leong, Caroline Yeoh

Research Collection Lee Kong Chian School Of Business

Singapore’s regionalisation strategy has been applied in various countries, such as China, Vietnam and India, through the establishment of industrial parks. The parks are marketed as a winning combination of the host country’s unique location advantages and Singapore style efficiency and management know-how. Singapore’s foray into India was marked by the setting up of the ITPL in Bangalore, and furthered by its venture into a future phase of HITEC City, based on her success in Bangalore. However, with global businesses shifting interests towards India, and competing industrial parks emerging to meet the increasing demand, ITPL is faced with stiff competition …
