A Semi-Parametric Estimator For Censored Selection Models With Endogeneity, Myoung-Jae Lee, Francis Vella
A Semi-Parametric Estimator For Censored Selection Models With Endogeneity, Myoung-Jae Lee, Francis Vella
Research Collection School Of Economics
We propose a semi-parametric least-squares estimator for a censored-selection (type 3 tobit) model under the mean independence of the outcome equation error u from the regressors given the selection indicator and its error term ɛ. This assumption is relatively weak in comparison to alternative estimators for this model and allows certain unknown forms of heteroskedasticity, an asymmetric error distribution, and an arbitrary relationship between the u and ɛ. The estimator requires only one-dimensional smoothing on the estimate of ɛ. We generalize the estimator to allow for an endogenous regressor whose equation contains an error w related to u and discuss …
Strategy Meets Evolution: Games Suppliers And Producers Play, Brishti Guha
Strategy Meets Evolution: Games Suppliers And Producers Play, Brishti Guha
Research Collection School Of Economics
Final goods producers, who may be intrinsically honest (a behavioral type) or opportunistic (strategic), play a repeated game of imperfect information with suppliers of an input of variable (and non-verifiable) quality. Returns to cheating are increasing in the proportion of intrinsically honest producers. If producers compete for another scarce input, adverse selection reduces this proportion enough to enforce universal honesty, whether at a high or a low quality equilibrium. This mechanism limits the proportion of behavioral types in the population of producers over a wide range of parameters: despite their inability to compete with opportunists, they are not wholly wiped …
More Efficient Estimation In Nonparametric Regression With Nonparametric Autocorrelated Errors, Liangjun Su, Aman Ullah
More Efficient Estimation In Nonparametric Regression With Nonparametric Autocorrelated Errors, Liangjun Su, Aman Ullah
Research Collection School Of Economics
We define a three-step procedure for more efficient estimation of the nonparametric regression mean with nonparametric autocorrelated errors. The procedure is based upon a nonparametric prewhitening transformation of the dependent variable that has to be estimated from the data by a local polynomial technique. We establish the asymptotic distribution of our estimator under weak dependence conditions and show that it is more efficient than the conventional local polynomial estimator. Furthermore, we consider criterion functions based on the linear exponential family, which include the local polynomial least squares criterion as a special case. Simulation evidence suggests that significant gains can be …
Energy Efficiency And Capacity For Tcp Traffic In Multi-Hop Wireless Networks, Sorav Bansal, Rajeev Shorey, Rajeev Gupta, Archan Misra
Energy Efficiency And Capacity For Tcp Traffic In Multi-Hop Wireless Networks, Sorav Bansal, Rajeev Shorey, Rajeev Gupta, Archan Misra
Research Collection School Of Computing and Information Systems
We study the performance metrics associated with TCP-regulated traffic in multi-hop, wireless networks that use a common physical channel (e.g., IEEE 802.11). In contrast to earlier analyses, we focus simultaneously on two key operating metrics—the energy efficiency and the transport-layer (TCP) throughput. Using analysis and simulations, we show how these metrics are strongly influenced by the radio transmission range of individual nodes. Due to tradeoffs between the individual packet transmission energy and the likelihood of retransmissions, the total energy consumption is a convex function of the number of hops (and hence, of the transmission range). On the other hand, the …
Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding
Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding
Research Collection Lee Kong Chian School Of Business
In an emerging economy, the alternative to government control is often no governance. We investigate the governance structure of government-linked companies (GLCs) in Singapore under the ownership/control structure of Temasek Holdings, the government holding entity, which typically owns substantial cash flow rights but disproportional control rights and exercises no operational control. We compare the financial and market performance of GLCs with non-GLCs, where each has a different set of governance structure, the key difference being government ownership. We show that Singaporean GLCs have higher valuations and better corporate governance than a control group of non-GLCs. The results hold even when …
Hungary: Holding Back The Tiers, Kenneth Benoit
Hungary: Holding Back The Tiers, Kenneth Benoit
Research Collection School of Social Sciences
Hungary has a particularly complicated electoral system: a type of mixed system that incorporates three tiers of seat allocation, the use of a proportional allocation formula, and the allocation of a number of seats by a two-round system in single-member constituencies. Examination of the strategic incentives facing parties explains some surprising outcomes, such as the majoritarian impact on the party system and the possibility of the second strongest party in votes becoming the strongest in seats. Despite its complexity and alleged shortcomings, it is unlikely to be abandoned; it serves the interests of the largest parties, and these effectively wield …
Music And Moral Geographies: Constructions Of "Nation" And Identity In Singapore, Lily Kong
Music And Moral Geographies: Constructions Of "Nation" And Identity In Singapore, Lily Kong
Research Collection School of Social Sciences
In this paper, I attempt to pull together sociological and geographical perspectives in the study of music to understand the ways in which pop and rock music are socio-cultural products with political and moral meanings and implications. I examine state engineering of moral panics, focusing on a case study of pop and rock music in post-independence Singapore. Such engineering is aimed at political and ideological ends, in particular, "nation"- building outcomes. In engineering moral panics through both discursive and legislative acts, the contours of a moral geography are delineated at various spatial scales. First, at the scale of the national …
Moore's Paradoxes And Conscious Belief, John N. Williams
Moore's Paradoxes And Conscious Belief, John N. Williams
Research Collection School of Social Sciences
For Moore, it is a paradox that although I would be absurd in asserting that (it is raining but I don’t believe it is) or that (it is raining but I believe it isn’t), such assertions might be true. But I would be also absurd in judging that the contents of such assertions are true. I argue for the strategy of explaining the absurdity of Moorean assertion in terms of conscious Moorean belief. Only in this way may the pathology of Moorean absurdity be adequately explained in terms of self-contradiction. David Rosenthal disagrees with this strategy. Ironically, his higher-order thought …
How Well Can We Target Resources With Quick-And-Dirty Data?: Empirical Results From Cambodia, Tomoki Fujii
How Well Can We Target Resources With Quick-And-Dirty Data?: Empirical Results From Cambodia, Tomoki Fujii
Research Collection School Of Economics
Proverty reduction is a top priority for international organizations, governments and non-gorvernmental organizations. The aid resources available for poverty reduction are, however, severely constrained in many countries. Minimizing the leakage of aid resources to the non-poor is a key to maximize poverty reduction with the limited amount of resources available. One Way to minimize such leakage to to target resources geographically. That is, policmakers can move resources to the poorest parts of the country. Geographic taregting can quite effective when poverty is unevenly distributed across the country, and this proves to be the case in many countries.
Central Asia's Transition After Fifteen Years: Growth And Policy Choices, Malcolm Dowling, Ganeshan Vignaraja
Central Asia's Transition After Fifteen Years: Growth And Policy Choices, Malcolm Dowling, Ganeshan Vignaraja
Research Collection School Of Economics
This paper presents a coherent and systematic analysis of the collapse and subsequent revival of the Central Asian Republics (CARs) since 1990. The focus is on the pattern of growth and structural change during the cycle of decline and subsequent revival in the CARs which have been inadequately analyzed in the literature on transition. The paper relates economic performance to initial conditions, country characteristics and policies. Within this framework, it proposes a simple typology of policies (including a new Type III set of policies on regional cooperation and industrial competitiveness) and relates them to the cycle of decline and revival …
Central Asia: Mapping Future Prospects, Malcolm Dowling, Ganeshan Wignaraja
Central Asia: Mapping Future Prospects, Malcolm Dowling, Ganeshan Wignaraja
Research Collection School Of Economics
Central Asia has emerged as one of the world’s fastest growing regions since the late 1990s and has shown notable development potential. This is significant for a region comprising largely of small landlocked economies with no access to the sea for trade. Among the advantages, of the region are its high- priced commodities (oil, gas, cotton and gold), reasonable infrastructure and human capital as legacies of Soviet rule; and a strategic location between Asia and Europe. Furthermore, many Central Asian Republics (CARs) have embarked on market-oriented economic reforms to boost economic performance and private sector competitiveness. Central Asia: Mapping Future …
Competition Policy In Indonesia, Malcolm Dowling
Competition Policy In Indonesia, Malcolm Dowling
Research Collection School Of Economics
The Indonesian economy was dominated by the government in the decades of the 1970s and 1980s through its control of major mining, manufacturing and agricultural activities. Hill (2000) estimates that as much as 40% of non-agricultural GDP was accounted for by government entities in the late 1980s There were still a lot of government corporations up until the late 1980s and early 1990s and governmental control over the banking system was still substantial.
Homeostasis And Well Being, Malcolm Dowling, Chin Fang Yap
Homeostasis And Well Being, Malcolm Dowling, Chin Fang Yap
Research Collection School Of Economics
The paper suggests that maintenance of a homeostatic equilibrium provides a rationale for many actions of economic agents. Homeostatic equilibrium has physical, economic, emotional, psychological and environmental dimensions. The characteristics of this equilibrium include feelings of safety, trust, connectedness with friends, family and community, and a predictable and welcoming social and work environment. Individuals generally make decisions that help them move toward and achieve this state of equilibrium. Departure from homeostasis reduces well being and stimulates agents to take actions that will return them to a state of homeostasis. This hypothesis is tested with probit analysis using sample responses from …
Effects Of Technological Improvement In The Ict Producing Sector On Business Activity, Hian Teck Hoon, Edmund S. Phelps
Effects Of Technological Improvement In The Ict Producing Sector On Business Activity, Hian Teck Hoon, Edmund S. Phelps
Research Collection School Of Economics
It seems to be taken for granted by many commentators that the sharp decline in prices of computers, telecommunications equipment and software resulting from the technological improvements in the information and communications technology (ICT)-producing sector is good for jobs and is a major driving force behind the non-inflationary employment miracle and booming stock market in the latter half of the nineties in the U.S. and their recurrence since 2004. We show that, in our model, a technical improvement in the ICT-producing sector by itself cannot explain a simultaneous increase in employment and a rise in firms’ valuation (or Tobin’s Q …
The Micro-Foundations Of Intertemporal Price Discrimination, Winston T. H. Koh
The Micro-Foundations Of Intertemporal Price Discrimination, Winston T. H. Koh
Research Collection School Of Economics
This paper investigates the optimality of intertemporal price discrimination for a durable-good monopoly in a model where infinitely-lived households face an intertemporal budget constraint, and consume both durable goods and non-durable goods. We prove that the optimal price of the durable good is not constant, and may decrease or increase over time. Some households may choose to purchase the durable good at a later date, and pay lower or higher prices, since the gain in discounted utility of consuming more of the non-durable good more than compensates for the loss in utility from delaying the consumption of the durable good. …

Functional Sunspot Equilibria, Shurojit Chatterji, Subir Chattopadhyay
Research Collection School Of Economics
Consider a one step forward looking model where agents believe that the equilibrium values of the state variable are determined by a function whose domain is the current value of the state variable and whose range is the value for the subsequent period. An agent's forecast for the subsequent period uses the belief, where the function that is chosen is allowed to depend on the current realization of an extrinsic random process, and is made with knowledge of the past values of the state variable but not the current value. The paper provides (and characterizes) the conditions for the existence …

This paper proposes a simple consistent nonparametric test of multivariate conditional symmetry based on the principle of characteristic functions. The test statistic is shown to be asymptotically normal under the null and consistent against any conditional asymmetric distributions.
Extending Economic Boundaries And Exporting Expertise: New Evidence On Singapore's Gambit In Indonesia, Vietnam And India, Caroline Yeoh, Siang Yeung Wong
Extending Economic Boundaries And Exporting Expertise: New Evidence On Singapore's Gambit In Indonesia, Vietnam And India, 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 twofold: 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 1 revisits Singapore's flagship projects in Indonesia, Vietnam and India. Evidence from on-site surveys and interviews are presented. This paper contends that progress in these privileged investment zones remains stymied by particular dependencies and challenges in the host environments.
Scalable Authentication Of Mpeg-4 Streams, Yongdong Wu, Robert H. Deng
Scalable Authentication Of Mpeg-4 Streams, Yongdong Wu, Robert H. Deng
Research Collection School Of Computing and Information Systems
This paper presents three scalable and efficient schemes for authenticating MPEG-4 streams: the Flat Authentication Scheme, the Progressive Authentication Scheme, and the Hierarchical Authentication Scheme. All the schemes allow authentication of MPEG-4 streams over lossy networks by integrating seamlessly digital signatures and erasure correction coding with MPEG-4's fine granular scalability. A prominent feature of our schemes is their "sign once, verify many ways" property, i.e., they generate only one digital signature per compressed MPEG-4 object group, but allow clients to verify the authenticity of any down-scaled version of the original signed object group.
Interface Between Ip And Competition Law In Taiwan, Kung-Chung Liu
Interface Between Ip And Competition Law In Taiwan, Kung-Chung Liu
Research Collection Yong Pung How School Of Law
The modernization of Taiwan’s intellectual property (IP) laws has been most marked in the last 10 to 15 years.] During that period, Taiwan also responded to U.S. Section 301 pressure by enacting and enforcing the Fair Trade Act of 1991, a general competition law. The issue of the interface between IP and antitrust law has gradually gained sigdcance in the last couple of years. To some extent, as its development in Taiwan testifies, competition law has circumscribed the scope of IP laws and inacted a spd-over effect on the IP laws. The ramification of competition law in Taiwan with regard …
Design Synthesis From Interaction And State-Based Specifications, Jun Sun, Jin Song Dong
Design Synthesis From Interaction And State-Based Specifications, Jun Sun, Jin Song Dong
Research Collection School Of Computing and Information Systems
Interaction-based and state-based modeling are two complementary approaches of behavior modeling. The former focuses on global interactions between system components. The latter concentrates on the internal states of individual components. Both approaches have been proven useful in practice. One challenging and important research objective is to combine the modeling power of both effectively and then use the combination as the basis for automatic design synthesis. We present a combination of interaction-based and state-based modeling, namely, Live Sequence Charts and Z, for system specification. We then propose a way of generating distributed design from the combinations. Our approach handles systems with …

Fabrication-Tolerant Active-Passive Integration Scheme For Vertically-Coupled Microring Resonators, Chyng Wen Tee, Ka Williams, Rv Penty, Ih White
Research Collection Lee Kong Chian School Of Business
The large-scale photonic integration of microring resonators in three dimensions made possible by recent developments in vertical coupling and wafer bonding technology is shown to be sensitive to lateral mask misalignment for the ring and bus waveguides introduced during the fabrication process. For a typical 20-μm radius, vertically coupled microring calculations reveal a linear relationship between deviation in the coupling coefficient and lateral misalignment. A coupling coefficient reduction of 50% is predicted for a lateral misalignment of 0.3 μm, which is typical for an alignment accuracy limited by the current state-of-the-art mask alignment process. The use of a wide multimode …
The Impact Of Certain And Uncertain Store Promotions On The Decision-Making Process In Product Choices, Cathy Yi Chen
The Impact Of Certain And Uncertain Store Promotions On The Decision-Making Process In Product Choices, Cathy Yi Chen
Research Collection Lee Kong Chian School Of Business
Various store promotions ranging from dollar-off discounts to sweepstakes can induce different affects among consumers. Built on recent studies on the uncertainty of incidental affect, this research examines how promotions differ in the feeling of uncertainty elicited, which, in turn, influence the decision-making process of product choices. Specifically, we demonstrate that “uncertain” promotions (e.g., sweepstakes) can increase the extent of systematic decision-making in a subsequent product choice relative to “certain” promotions (e.g., discount) when the choice is easy. But the pattern is reversed when the choice is difficult. The implications to the incidental affect and promotion research are discussed.
Intraday Stock Prices, Volume, And Duration: A Nonparametric Conditional Density Analysis, Anthony S. Tay, Christopher Ting
Intraday Stock Prices, Volume, And Duration: A Nonparametric Conditional Density Analysis, Anthony S. Tay, Christopher Ting
Research Collection School Of Economics
We investigate the distribution of high-frequency price changes, conditional on trading volume and duration between trades, on four stocks traded on the New York Stock Exchange. The conditional probabilities are estimated nonparametrically using local polynomial regression methods. We find substantial skewness in the distribution of price changes, with the direction of skewness dependent on the sign of trade. We also find that the probability of larger price changes increases with volume, but only for trades that occur with longer durations. The distribution of price changes vary with duration primarily when volume is high.
Does Governance Matter? Yes, No Or Maybe Some Evidence From Developing Asia, M. G. Quibria
Does Governance Matter? Yes, No Or Maybe Some Evidence From Developing Asia, M. G. Quibria
Research Collection School Of Economics
This paper seeks to explore the relationship between economic growth and governance performance in Asian developing economies. This exploration yields some interesting conclusions. First, notwithstanding its tremendous economic achievements, the state of governance in Asia is not stellar by international comparison. Indeed, a majority of these countries seem to suffer from a governance deficit. Second, contrary to our expectation, data do not suggest any strong positive link between governance and growth: paradoxically, countries that exhibit surpluses in governance on average grew much slower than those with deficits. The paper ends with some conjecture about this apparent paradox.
Perceptual Fluency, Attitudes And Choice: Special Session: The Role Of Metacognition In Consumers’ Judgments, Andrew A. Mitchell, Seh-Woong Chung
Perceptual Fluency, Attitudes And Choice: Special Session: The Role Of Metacognition In Consumers’ Judgments, Andrew A. Mitchell, Seh-Woong Chung
Research Collection Lee Kong Chian School Of Business
In a series of studies we examine the relationship between perceptual fluency, attitudes and their accessibility and choice from a limited set of brands. We hypothesize that under these conditions, brand choice is a two-stage process. The first stage is a recognition stage where certain brands will "stand out" in the environment. The second stage is a choice stage, where consumers use information about the brands, which is stored in memory to make a choice.
