Set Inference For Semiparametric Discrete Games, Kyoo-Il Kim Sep 2006

Set Inference For Semiparametric Discrete Games, Kyoo-Il Kim

Research Collection School Of Economics

We consider estimation and inference of parameters in discrete games allowing for multiple equilibria, without using an equilibrium selection rule. We do a set inference while a game model can contain infinite dimensional parameters. Examples can include signaling games with discrete types where the type distribution is nonparametrically specified and entry-exit games with partially linear payoffs functions. A consistent set estimator and a confidence interval of a function of parameters are provided in this paper. We note that achieving a consistent point estimation often requires an information reduction. Due to this less use of information, we may end up a …

Semiparametric Estimation Of Signaling Games, Kyoo-Il Kim Sep 2006

Semiparametric Estimation Of Signaling Games, Kyoo-Il Kim

Research Collection School Of Economics

This paper studies an econometric modeling of a signaling game with two players where one player has one of two types. In particular, we develop an estimation strategy that identifies the payoffs structure and the distribution of types from data of observed actions. We can achieve uniqueness of equilibrium using a refinement, which enables us to identify the parameters of interest. In the game, we consider non-strategic public signals about the types. Because the mixing distribution of these signals is nonparametrically specified, we propose to estimate the model using a sieve conditional MLE. We achieve the consistency and the asymptotic …

Video-Based Versus Written Situational Judgment Tests: A Comparison In Terms Of Predictive Validity, Filip Lievens, Paul R. Sackett Sep 2006

Video-Based Versus Written Situational Judgment Tests: A Comparison In Terms Of Predictive Validity, Filip Lievens, Paul R. Sackett

Research Collection Lee Kong Chian School Of Business

In this study, the authors examined whether video-based situational judgment tests (SJTs) have higher predictive validity than written SJTs (keeping verbal content constant). The samples consisted of 1, 159 students who completed a video-based version of an SIT and 1,750 students who completed the same SIT in a written format. The study was conducted in a high stakes testing context. The video-based version of an interpersonally oriented SJT had a lower correlation with cognitive ability than did the written version. It also had higher predictive and incremental validity for predicting interpersonally oriented criteria than did the written version. In this …

Uniform Convergence Rate Of The Snp Density Estimator And Testing For Similarity Of Two Unknown Densities, Kyoo-Il Kim Sep 2006

Uniform Convergence Rate Of The Snp Density Estimator And Testing For Similarity Of Two Unknown Densities, Kyoo-Il Kim

Research Collection School Of Economics

This paper studies the uniform convergence rate of the turncated SNP (semi-nonparametric) density estimator. Using the uniform convergence rate result we obtain, we propose a test statistic testing the equivalence of two unknown densities where two densities are estimated using the SNP estimator and supports of densities are possibly unbounded.

Government Procurement: A View From Asia, Locknie Hsu Sep 2006

Government Procurement: A View From Asia, Locknie Hsu

Research Collection Yong Pung How School Of Law

There is no single approach to government procurement regulation among Asian countries. While some are signatories to the WTO's Government Procurement Agreement (GPA), others are not. Some have deliberate policies which confer preferences on domestic suppliers of goods and services. Even so, some have embarked on changing their GP regimes independently of WTO requirements. Yet others appear to be prepared to make changes in tandem with the negotiation of bilateral or regional free trade agreements. This article examines government procurement from these varied perspectives of Asian countries.

Performance, Growth And Earnings Management, Chi Wen Jevons Lee, Laura Yue Li, Heng Yue Sep 2006

Performance, Growth And Earnings Management, Chi Wen Jevons Lee, Laura Yue Li, Heng Yue

Research Collection School Of Accountancy

We study the relationship between the amount of managed earnings and firms' earnings performance and expected growth in a reporting model, where managers manipulate earnings to influence the valuation of firms' equity while bearing a cost that is increasing and convex in the amount of managed earnings. In the unique revealing equilibrium to the model, firms with higher performance and growth over-report earnings by a larger amount because price responsiveness increases with earnings performance and growth. And earnings quality, defined as the proportion of true economic earnings in total reported earnings, increases with earnings performance but decreases with earnings growth. …

Multivariate Stochastic Volatility Models: Bayesian Estimation And Model Comparison, Jun Yu, Renate Meyer Sep 2006

Multivariate Stochastic Volatility Models: Bayesian Estimation And Model Comparison, Jun Yu, Renate Meyer

Research Collection School Of Economics

In this paper we show that fully likelihood-based estimation and comparison of multivariate stochastic volatility (SV) models can be easily performed via a freely available Bayesian software called WinBUGS. Moreover, we introduce to the literature several new specifications that are natural extensions to certain existing models, one of which allows for time-varying correlation coefficients. Ideas are illustrated by fitting, to a bivariate time series data of weekly exchange rates, nine multivariate SV models, including the specifications with Granger causality in volatility, time-varying correlations, heavy-tailed error distributions, additive factor structure, and multiplicative factor structure. Empirical results suggest that the best specifications …

Relationships, Layoffs, And Organizational Resilience: Airline Industry Responses To September 11, Jody H. Gittell, Kim Cameron, Sandy Lim, Victor Rivas Sep 2006

Relationships, Layoffs, And Organizational Resilience: Airline Industry Responses To September 11, Jody H. Gittell, Kim Cameron, Sandy Lim, Victor Rivas

Research Collection School of Social Sciences

The terrorist attacks of September 11, 2001, affected the U.S. airline industry more than almost any other industry. Certain airlines emerged successful and demonstrated remarkable resilience while others languished. This investigation identifies reasons why some airline companies recovered successfully after the attacks while others struggled. Evidence is provided that layoffs after the crisis, although intended to foster recovery, instead inhibited recovery throughout the 4 years after the crisis. But, layoffs after the crisis were strongly correlated with lack of financial reserves and lack of a viable business model prior to the crisis. Digging deeper, the authors find that having a …

Higher Order Bias Correcting Moment Equation For M-Estimation And Its Higher Order Efficiency, Kyoo-Il Kim Sep 2006

Higher Order Bias Correcting Moment Equation For M-Estimation And Its Higher Order Efficiency, Kyoo-Il Kim

Research Collection School Of Economics

This paper studies an alternative bias correction for the M-estimator, which is obtained by correcting the moment equation in the spirit of Firth (1993). In particular, this paper compares the stochastic expansions of the analytically bias-corrected estimator and the alternative estimator and finds that the third-order stochastic expansions of these two estimators are identical. This implies that at least in terms of the third order stochastic expansion, we cannot improve on the simple one-step bias correction by using the bias correction of moment equations. Though the result in this paper is for a fixed number of parameters, our intuition may …

On The Magnet Effect Of Foreign Direct Investment, Pao Li Chang, Chia-Hui Lu Sep 2006

On The Magnet Effect Of Foreign Direct Investment, Pao Li Chang, Chia-Hui Lu

Research Collection School Of Economics

We extend Antras and Helpman (2004) on firm heterogeneity and organizational choice to a dynamic setting with FDI uncertainty, in which the probability of investment failure decreases with the host country's infrastructure level and increases with the technological complexity facing each firm. Moreover, it decreases over time as the accumulated mass of firms succeeding in FDI increases. We show that a minimum level of infrastructure is required to trigger a first wave of industrial migration. We then formalize the often noted "magnet effect" of FDI - the first wave of industrial migration generates positive externality (information spillover) for subsequent investors, …

An Agent-Based Model Of Crisis-Driven Ethnic Migration, Michael Makowsky, Tamas Makany, Patrick Meier, Jorge Tavares Sep 2006

An Agent-Based Model Of Crisis-Driven Ethnic Migration, Michael Makowsky, Tamas Makany, Patrick Meier, Jorge Tavares

Research Collection Lee Kong Chian School Of Business

The literature on ethnic migration suggests that natural disasters, armed conflict, economics and cultural networks are key drivers of migration. The dearth of georeferenced ethnic data, however, limits the value of econometric analysis. We build an agent-based model to simulate crisis-driven migration. Agents within a multi-ethnic population monitor their spatial environments to formulate perceptions of the risk of being persecuted. The expected utility of staying within a given neighborhood is inversely related to the perceived probability of persecution. Cultural networks temper an agent's security calculus, with strong social ties dampening the human security dilemma. Agents express preferences regarding the different …

Protection For Sale Under Monopolistic Competition: An Empirical Investigation, Pao Li Chang, Myoung-Jae Lee Aug 2006

Protection For Sale Under Monopolistic Competition: An Empirical Investigation, Pao Li Chang, Myoung-Jae Lee

Research Collection School Of Economics

This paper proposes a general empirical framework to estimate the protection-for-sale model, where the protection regime shifts according to a sector's market structure (perfectly or monopolistically competitive). We base the protection structure on Grossman and Helpman (1994) for the subset of perfectly competitive sectors and on Chang (2005) for the subset of monopolistically competitive sectors. The two protection regimes are simultaneously estimated with joint constraints. The results of the J-test consistently reject the homogeneous (perfect competition) protection-for-sale model often adopted in previous literature and suggest a direction of improvement toward the proposed heterogeneous protection structure model.

The Coevolution Of Economic And Political Development, Fali Huang Aug 2006

The Coevolution Of Economic And Political Development, Fali Huang

Research Collection School Of Economics

This paper establishes a simple model of long run economic and political development, which is driven by the inherent technical features of different production factors, and political conflicts among factor owners on how to divide the outputs. The main capital form in economy evolves from land to physical capital and then to human capital, which enables their respective owners (landlords, capitalists, and workers) to gain political powers in the same sequence, shaping the political development path from monarchy to elite ruling and finally to full suffrage. When it is too costly for any group of factor owners to repress others, …

Characterizing Exchange Rate Policy In East Asia: A Reconsideration, Hwee Kwan Chow Aug 2006

Characterizing Exchange Rate Policy In East Asia: A Reconsideration, Hwee Kwan Chow

Research Collection School Of Economics

Frankel and Wei [Frankel, J. A., & Wei, S.-J. (1994). Yen bloc or dollar bloc: Exchange rate policies of the East Asian economies. In I. Takatoshi & A. Krueger (Eds.), Macroeconomic linkages. Chicago: University of Chicago Press] developed and popularized a method for uncovering the implicit weights assigned to major international currencies constituting a currency basket. We extend the methodology in two dimensions: include regional competitive pressure and employ a vector autoregressive (VAR) model to overcome simultaneity bias. With these modifications, we confirm the prominent role of the US dollar in the exchange rate policy of East Asian economies beyond …

The Sociality Of Cultural Industries: Hong Kong's Cultural Policy And Film Industry, Lily Kong Aug 2006

The Sociality Of Cultural Industries: Hong Kong's Cultural Policy And Film Industry, Lily Kong

Research Collection School of Social Sciences

In this article, I explore the sociality of cultural industries by analyzing the film industry in Hong Kong. In particular, the social networks and relationships at multiple scales – across national boundaries, within local settings and on production sets – are examined, revealing their critical role in contributing to the health of the film industry. The risks faced at various steps of the production, marketing and distribution process are ameliorated by trust relations, built up through time between social actors in spontaneous ways. While Hong Kong cultural policy in part seeks to create the social and spatial contexts within which …

The Political Economy Of Poverty Reduction: A Comparative Study Of Two Chinese Provinces, John A. Donaldson Aug 2006

The Political Economy Of Poverty Reduction: A Comparative Study Of Two Chinese Provinces, John A. Donaldson

Research Collection School of Social Sciences

Is growth good for the poor? In theory, yes. As one influential report on China’s “War on Poverty” suggested, ”Obviously robust economic growth helps reduce poverty, as long as the gains are reasonably distributed” (Rozelle et al. 2000). In practice as well, growth is often a crucial ingredient in the poverty reduction recipe. While this relationship is well founded, important exceptions present themselves – some areas grow, but poverty persists; the economies of other areas remain apparently stagnant, yet poverty diminishes. These exceptions, if studied, will not only illuminate further the causal relationship between these two concepts, but also provide …

Richard Rorty And Moral Progress In Global Relations, Eduard Jordaan Aug 2006

Richard Rorty And Moral Progress In Global Relations, Eduard Jordaan

Research Collection School of Social Sciences

Richard Rorty's navigation of the pitfalls of the cosmopolitan-communitarian debate, concern with human suffering, recognition of the contingency of communal identities and relationships, and his endorsement of liberal societies, by definition inclusive and always in search of a greater justice, make it appear as though his thought can guide us towards greater concern for the world's poor. However, this article questions the progressive potential of Rorty's thought. Obstacles to such (global) moral progress include Rorty's unquestioned statism and his focus on internal outsiders who are suffering and/or oppressed, instead of external outsiders beyond national borders; his insistence on a public-private …

Spectral Density Estimation And Robust Hypothesis Testing Using Steep Origin Kernels Without Truncation, Peter C.B Philips, Yixiao Sun, Sainan Jin Aug 2006

Spectral Density Estimation And Robust Hypothesis Testing Using Steep Origin Kernels Without Truncation, Peter C.B Philips, Yixiao Sun, Sainan Jin

Research Collection School Of Economics

A new class of kernels for long-run variance and spectral density estimation is developed by exponentiating traditional quadratic kernels. Depending on whether the exponent parameter is allowed to grow with the sample size, we establish different asymptotic approximations to the sampling distribution of the proposed estimators. When the exponent is passed to infinity with the sample size, the new estimator is consistent and shown to be asymptotically normal. When the exponent is fixed, the new estimator is inconsistent and has a nonstandard limiting distribution. It is shown via Monte Carlo experiments that, when the chosen exponent is small in practical …

History, Identity, And Security: Producing And Consuming Nationalism In China, William A. Callahan Aug 2006

History, Identity, And Security: Producing And Consuming Nationalism In China, William A. Callahan

Research Collection School of Social Sciences

Chinese nationalism has ignited much debate among academics and the general public in both China and the West. Rather than search for the true core of Chinese nationalism, this essay will examine the curious custom of National Humiliation Day as an oblique entry into the politics of identity. The nation is not simply a question of people or territory, the author contends, but of time: the national time scripted by events such as National Humiliation Day. By comparing the differing practices of the holiday as it was celebrated in the early twentieth century and is observed in the early twenty-first …

Knowledges Of The Creative Economy: Towards A Relational Geography Of Diffusion And Adaptation In Asia, Lily Kong, Chris Gibson, Louisa-May Khoo, Anne-Louise Semple Aug 2006

Knowledges Of The Creative Economy: Towards A Relational Geography Of Diffusion And Adaptation In Asia, Lily Kong, Chris Gibson, Louisa-May Khoo, Anne-Louise Semple

Research Collection School of Social Sciences

Recent dialogues in geography and the social sciences have reminded researchers of the extent to which academic and policy knowledges are socially and spatially embedded-that is, they circulate through formal and informal systems of publishing, exchange, commodification and cultural influence. Academic and policy knowledges are, in short, very much a part of the creative economy. In light of this, our paper surveys knowledges of the creative economy itself, as reflected in a geography of industry reports and government policy statements in selected Asian countries. Using a post-positivist framework adapted from diffusion theory, we critically interpret the circulation, mutation and adaptation …

The Law Of International Commercial Arbitration In Singapore, Warren B. Chik Jul 2006

The Law Of International Commercial Arbitration In Singapore, Warren B. Chik

Research Collection Yong Pung How School Of Law

The Singapore dispute resolution landscape entered the new millennium with the reconstruction of the dual carriageway for arbitration. In 2002, the old road to arbitral resolution of disputes ( i.e. , the old Arbitration Act and the old International Arbitration Act ) were reconstructed and what emerged were two updated legislations: the Arbitration Act and the International Arbitration Act . At about the same time, the Singapore International Arbitration Centre (SIAC) also diversified with the introduction of a new set of Domestic Arbitration Rules.

Direct And Indirect Effects Of Third-Party Relationships On Interpersonal Trust, Donald L. Ferrin, Kurt T. Dirks, Pri P. Shah Jul 2006

Direct And Indirect Effects Of Third-Party Relationships On Interpersonal Trust, Donald L. Ferrin, Kurt T. Dirks, Pri P. Shah

Research Collection Lee Kong Chian School Of Business

Past studies of the determinants of interpersonal trust have focused primarily on how trust forms in isolated dyads. Yet within organizations, trust typically develops between individuals who are embedded in a complex web of existing and potential relationships. In this article, the authors identify 3 alternative ways in which a trustor and trustee may be linked to each other via third parties: network closure (linked via social interactions with third parties), trust transferability (linked via trusted third parties), and structural equivalence (linked via the similarity of their relationships with all potential third parties within the organization). Each of these is …

A Modified Family Of Power Transformations, Zhenlin Yang Jul 2006

A Modified Family Of Power Transformations, Zhenlin Yang

Research Collection School Of Economics

A modified family of power transformation, called the dual power transformation, is proposed. The new transformation is shown to possess properties similar to those of the well-known Box-Cox power transformation, but overcomes the long-standing truncation problem of the latter. It generates a rich family of distributions that is seen to be very useful in modeling and analysis of durations and event-times.

Weak Monotonicity Characterizes Deterministic Dominant-Strategy Implementation, Sushil Bikhchandani, Shurojit Chatterji, Ron Lavi, Ahuva Mu'alem, Noam Nisan, Arunava Sen Jul 2006

Weak Monotonicity Characterizes Deterministic Dominant-Strategy Implementation, Sushil Bikhchandani, Shurojit Chatterji, Ron Lavi, Ahuva Mu'alem, Noam Nisan, Arunava Sen

Research Collection School Of Economics

We characterize dominant-strategy incentive compatibility with multidimensional types. A deterministic social choice function is dominant-strategy incentive compatible if and only if it is weakly monotone (W-Mon). The W-Mon requirement is the following: If changing one agent's type (while keeping the types of other agents fixed) changes the outcome under the social choice function, then the resulting difference in utilities of the new and original outcomes evaluated at the new type of this agent must be no less than this difference in utilities evaluated at the original type of this agent.

Exchange-Rate Systems And Interest-Rate Behaviour: The Experience Of Hong Kong And Singapore, Yiu Kuen Tse, Paul S. L. Yip Jul 2006

Exchange-Rate Systems And Interest-Rate Behaviour: The Experience Of Hong Kong And Singapore, Yiu Kuen Tse, Paul S. L. Yip

Research Collection School Of Economics

The Currency Board System in Hong Kong and the monitoring band system in Singapore are important benchmarks for two different exchange-rate systems. In this paper we consider the implications of the two exchange-rate systems on the interest-rate behaviour of the two economies. We examine the domestic–US interest differentials under the two exchange-rate regimes during the Asian Financial Crisis as well as the pre-and post-crisis periods. Using a bivariate generalized autoregressive conditional heteroscedasticity model, we also investigate whether there is any change in the correlation between the domestic and US interest rates due to the Asian Financial Crisis.

'A Hundred Flowers Bloom': The Re-Emergence Of The Chinese Press In Post-Suharto Indonesia, Chang Yau Hoon Jul 2006

'A Hundred Flowers Bloom': The Re-Emergence Of The Chinese Press In Post-Suharto Indonesia, Chang Yau Hoon

Research Collection School of Social Sciences

During the whole 32 years of Suharto’s regime (1966–98), Chinese publications and the use of Chinese language in public were officially banned in Indonesia. As a result, printed matter in Chinese characters that entered Indonesia was classified as ‘prohibited imports’ (Heryanto 1999: 327). This prohibition came to an end after the fall of Suharto, as part of the process of democratization and Reformasi. The post-Suharto era of Reformasi is thus celebrated for the dramatic revival of the freedom of the press and media in Indonesia and many previously banned as well as new publications have emerged since Suharto’s fall. The …

Voter Strategies With Restricted Choice Menus, Kenneth Benoit, Daniela Giannetti, Michael Laver Jul 2006

Voter Strategies With Restricted Choice Menus, Kenneth Benoit, Daniela Giannetti, Michael Laver

Research Collection School of Social Sciences

Mixed-member electoral systems require voters simultaneously to cast ballots in single-member districts (SMD) and multimember, proportional representation (PR) constituencies. It may be that not all parties offer candidates in both electoral contexts, however. In this event would-be voters for some parties may find themselves ‘frustrated’ by the restricted choice menu on offer in the SMD, being effectively forced to split their vote between different parties. Here we explore the different behaviours of frustrated voters in the 1996 mixed-member election to Italy’s Chamber of Deputies, characterizing these as being either in some sense non-strategic (concerned above all with the relative policy …
