Labor Supply Responses To The 1990s Japanese Tax Reforms, Ken Yamada
Labor Supply Responses To The 1990s Japanese Tax Reforms, Ken Yamada
Research Collection School Of Economics
The consumption-leisure choice model implies that an exogenous change in tax rates will induce a change in labor supply. This implication is expected to be important to labor supplied by secondary earners under a progressive tax system when spousal income alters effective marginal tax rates. This paper examines labor supply responses to the income tax changes associated with Japanese tax reforms during the 1990s. The results indicate that the hours-of-work elasticity with respect to the net-of-tax rate is 0.8 for married women.
Risk And The Technology Content Of Fdi: A Dynamic Model, Pao Li Chang, Chia-Hui Lu
Risk And The Technology Content Of Fdi: A Dynamic Model, Pao Li Chang, Chia-Hui Lu
Research Collection School Of Economics
This paper incorporates risk into the FDI decisions of firms. The risk of FDI failure increases with the gap between the South's technology frontier and the technology complexity of a firm's product. This leads to a double-crossing sorting pattern of FDI firms of intermediate technology levels are more likely than others to undertake FDI. It is with the attempt to relax the upper bound of the technology content of FDI, we argue, that many FDI policies are created. The theory's predictions are consistent with the empirical pattern of FDI in China by US and Taiwanese manufacturing firms.
Testing For Multiple Bubbles, Peter C. B. Phillips, Shu-Ping Shi, Jun Yu
Testing For Multiple Bubbles, Peter C. B. Phillips, Shu-Ping Shi, Jun Yu
Research Collection School Of Economics
Identifying explosive bubbles that are characterized by periodically collapsing behavior over time has been a major concern in the literature and is of great importance for practitioners. The complexity of the nonlinear structure in multiple bubble phenomena diminishes the discriminatory power of existing tests, as evidenced in early simulations conducted by Evans (1991). Multiple collapsing bubble episodes within the same sample period make bubble diagnosis particularly difficult and complicate attempts at econometric dating. The present paper systematically investigates these issues and develops new procedures for practical implementation and surveillance strategies by central banks. We show how the testing procedure and …
Bayesian Hypothesis Testing In Latent Variable Models, Yong Li, Jun Yu
Bayesian Hypothesis Testing In Latent Variable Models, Yong Li, Jun Yu
Research Collection School Of Economics
Hypothesis testing using Bayes factors (BFs) is known not to be well defined under the improper prior. In the context of latent variable models, an additional problem with BFs is that they are difficult to compute. In this paper, a new Bayesian method, based on decision theory and the EM algorithm, is introduced to test a point hypothesis in latent variable models. The new statistic is a by-product of the Bayesian MCMC output and, hence, easy to compute. It is shown that the new statistic is easy to interpret and appropriately defined under improper priors because the method employs a …
Specification Sensitivities In Right-Tailed Unit Root Testing, Shu-Ping Shi, Peter C. B. Phillips, Jun Yu
Specification Sensitivities In Right-Tailed Unit Root Testing, Shu-Ping Shi, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
Right-tailed unit root tests have proved promising for detecting exuberance in economic and financial activities. Like left-tailed tests, the limit theory and test performance are sensitive to the null hypothesis and the model specification used in parameter estimation. This paper aims to provide some empirical guidelines for the practical implementation of right-tailed unit root tests, focusing on the sup ADF test of Phillips, Wu and Yu (2011), which implements a right-tailed ADF test repeatedly on a sequence of forward sample recursions. We analyze and compare the limit theory of the sup ADF test under different hypotheses and model specifications. The …
Crowding-Out Effect Of The Current Food Stamp Subsidy Scheme, Yi Zhang
Crowding-Out Effect Of The Current Food Stamp Subsidy Scheme, Yi Zhang
Research Collection School Of Economics
We construct a model to illustrate that the current food stamp subsidy scheme fails to achieve its stated aim due to the crowding-out effect. More specifically, if the household income is sufficiently low, only a corner solution exists, and a full subsidy is needed.

Growth, Opportunity, And Inequality: Some Empirics From Singapore, Kong Weng Ho
Growth, Opportunity, And Inequality: Some Empirics From Singapore, Kong Weng Ho
Research Collection School Of Economics
While the strategy of openness had earned Singapore rapid economic growth, upward social mobility, and possibly decreasing inequality in the early years of development, the more recent years has seen increasing inequality. With this inequality comes an underlying possibly diminished upward inter-generational mobility, due to skill-biased growth processes, skill-biased parental influence, liberalisation in the education industry, and structural changes in the society, which hurt the human capital accumulation of children in families under economic and intra-household stresses. In particular, paternal influence on educational aspirations and attainment is more pronounced than maternal influence. Non-Chinese and youths from disrupted families are worse …
Recent Developments In European Bank Competition, Juliana Yu Sun
Recent Developments In European Bank Competition, Juliana Yu Sun
Research Collection School Of Economics
This paper investigates the degree of bank competition in the euro area, the U.S. and U.K. before and after the recent financial crisis, and revisits the issue whether the introduction of EMU and the euro have had any impact on bank competition. The results suggest that the level of bank competition converged across euro area countries in the wake of the EMU. The recent global financial crisis led to a fall in competition in several countries and especially where large credit and housing booms had preceded the crisis...
Preferences, Prisoners And Private Information: Was Socrates Rational At His Trial?, Brishti Guha
Preferences, Prisoners And Private Information: Was Socrates Rational At His Trial?, Brishti Guha
Research Collection School Of Economics
Using concepts from game theory, political economy, law and economics and the economics of asymmetric information, we describe the economics of one of the most famous trials in history—that of the Athenian philosopher Socrates. We discuss the question of whether Socrates’ actions during his trial were rational, using two different models. Our analysis sheds some light on institutional efficiency in trials that followed the classical Athenian pattern.
Pirates And Traders: Some Economics Of Pirate-Infested Seas, Brishti Guha, Ashok S. Guha
Pirates And Traders: Some Economics Of Pirate-Infested Seas, Brishti Guha, Ashok S. Guha
Research Collection School Of Economics
Even where all agents are risk-neutral, merchants can insure themselves against piracy. Such self-insurance is surprisingly invulnerable to moral hazard. Further, there exist a patrolling intensity and/or penalties for captured pirates which, along with mercantile self-insurance, could eliminate piracy.

Mr Chen Show Mao of the Workers' Party lamented in his speech recently that wages in Singapore are not increasing as fast as the country's gross domestic product growth, highlighting that most of the growth went to corporate profits and wage income for top earners.
Dangerous To Draw Down Reserves, Augustine H. H. Tan
Dangerous To Draw Down Reserves, Augustine H. H. Tan
Research Collection School Of Economics
As at the end of last year, our official reserves stood at $288 billion compared to a gross domestic product of $304 billion and bank deposits (domestic bank units or DBU) of $781 billion. In the event of a financial meltdown, the reserves would be far too small to bail out our banks. During the recent global financial crisis I was very anxious for Singapore when the Monetary Authority of Singapore announced a guarantee (until end last year) for all our DBU deposits of up to $150 billion.

Instrumental Variable Quantile Estimation Of Spatial Autoregressive Models, Liangjun Su, Zhenlin Yang
Instrumental Variable Quantile Estimation Of Spatial Autoregressive Models, Liangjun Su, Zhenlin Yang
Research Collection School Of Economics
We propose a spatial quantile autoregression (SQAR) model, which allows cross-sectional dependence among the responses, unknown heteroscedasticity in the disturbances, and heterogeneous impacts of covariates on different points (quantiles) of a response distribution. The instrumental variable quantile regression (IVQR) method of Chernozhukov and Hansen (2006) is generalized to allow the data to be non-identically distributed and dependent, an IVQR estimator for the SQAR model is then defined, and its asymptotic properties are derived. Simulation results show that this estimator performs well in finite samples at various quantile points. In the special case of spatial median regression, it outperforms the conventional …

Asymptotic Theory For Zero Energy Functionals With Nonparametric Regression Applications, Qiying Wang, Peter C. B. Phillips
Asymptotic Theory For Zero Energy Functionals With Nonparametric Regression Applications, Qiying Wang, Peter C. B. Phillips
Research Collection School Of Economics
A local limit theorem is given for the sample mean of a zero energy function of a nonstationary time series involving twin numerical sequences that pass to infinity. The result is applicable in certain nonparametric kernel density estimation and regression problems where the relevant quantities are functions of both sample size and bandwidth. An interesting outcome of the theory in nonparametric regression is that the linear term is eliminated from the asymptotic bias. In consequence and in contrast to the stationary case, the Nadaraya-Watson estimator has the same limit distribution (to the second order including bias) as the local linear …
Bias In Estimating Multivariate And Univariate Diffusions, Xiaohu Wang, Peter C. B. Phillips, Jun Yu
Bias In Estimating Multivariate And Univariate Diffusions, Xiaohu Wang, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
Multivariate continuous time models are now widely used in economics and finance. Empirical applications typically rely on some process of discretization so that the system may be estimated with discrete data. This paper introduces a framework for discretizing linear multivariate continuous time systems that includes the commonly used Euler and trapezoidal approximations as special cases and leads to a general class of estimators for the mean reversion matrix. Asymptotic distributions and bias formulae are obtained for estimates of the mean reversion parameter. Explicit expressions are given for the discretization bias and its relationship to estimation bias in both multivariate and …
Infinite Density At The Median And The Typical Shape Of Stock Return Distributions, Chirok Han, Jin Seo Cho, Peter C. B. Phillips
Infinite Density At The Median And The Typical Shape Of Stock Return Distributions, Chirok Han, Jin Seo Cho, Peter C. B. Phillips
Research Collection School Of Economics
Statistics are developed to test for the presence of an asymptotic discontinuity (or infinite density or peakedness) in a probability density at the median. The approach makes use of work by Knight (1998) on L(1) estimation asymptotics in conjunction with nonparametric kernel density estimation methods. The size and power of the tests are assessed, and conditions under which the tests have good performance are explored in simulations. The new methods are applied to stock returns of leading companies across major U.S. industry groups. The results confirm the presence of infinite density at the median as a new significant empirical evidence …
The People Want The Fall Of The Regime: Schooling, Political Protest, And The Economy, Filipe R. Campante, Davin Chor
The People Want The Fall Of The Regime: Schooling, Political Protest, And The Economy, Filipe R. Campante, Davin Chor
Research Collection School Of Economics
We provide evidence that economic circumstances are a key intermediating variable for understanding the relationship between schooling and political protest. Using the World Values Survey, we find that individuals with higher levels of schooling, but whose income outcomes fall short of that predicted by their biographical characteristics, in turn display a greater propensity to engage in protest activities. We discuss a number of interpretations that are consistent with this finding, including the idea that economic conditions can affect how individuals trade off the use of their human capital between production and political activities. Our results could also reflect a link …
Decomposing The Changes Of The Divisia Price Index: Application To Inflation In The Philippines, Tomoki Fujii
Decomposing The Changes Of The Divisia Price Index: Application To Inflation In The Philippines, Tomoki Fujii
Research Collection School Of Economics
We propose a method to decompose the logarithmic change of the Divisia price index into the pure price effect, the preference effect and the substitution effect. Our empirical results in the Philippines shows the effects of preference change on the Divisia price index are heterogeneous but positive across all regions and income deciles. However, they are dominated by the pure price effect.
Corrigendum To "A Gaussian Approach For Continuous Time Models Of The Short Term Interest Rate", Peter C. B. Phillips, Jun Yu
Corrigendum To "A Gaussian Approach For Continuous Time Models Of The Short Term Interest Rate", Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
An error is corrected in Yu and Phillips (2001) (Econometrics Journal, 4, 210-224) where a time transformation was used to induce Gaussian disturbances in the discrete time equivalent model. It is shown that the error process in this model is not a martingale and the Dambis, Dubins-Schwarz (DDS) theorem is not directly applicable. However, a detrended error process is a martingale, the DDS theorem is applicable, and the corresponding stopping time correctly induces Gaussianity. We show that the two stopping time sequences differ by O(a2), where a is the pre-specified normalized timing constant.
Wage Subsidies In A Program For Economic Inclusion And Growth, Hian Teck Hoon
Wage Subsidies In A Program For Economic Inclusion And Growth, Hian Teck Hoon
Research Collection School Of Economics
This paper is in three parts. The first part discusses the workings of a wage subsidy scheme in boosting employment and earnings of workers. The second part reviews the empirical evidence on the effectiveness of wage subsidy schemes in countries that have implemented them both as countercyclical policies as well as structural programs to boost long-term earnings and employment of low wage workers. The third part looks at Singapore as a case study of how wage subsidies have been used in a program for generating economic inclusion both in the context of growth as well as in the context of …

Explosive Behavior In The 1990s Nasdaq: When Did Exuberance Escalate Asset Values?, Peter C. B. Phillips, Yangru Wu, Jun Yu
Research Collection School Of Economics
A recursive test procedure is suggested that provides a mechanism for testing explosive behavior, date stamping the origination and collapse of economic exuberance, and providing valid confidence intervals for explosive growth rates. The method involves the recursive implementation of a right-side unit root test and a sup test, both of which are easy to use in practical applications, and some new limit theory for mildly explosive processes. The test procedure is shown to have discriminatory power in detecting periodically collapsing bubbles, thereby overcoming a weakness in earlier applications of unit root tests for economic bubbles. An empirical application to the …

Double-Edged Transparency In Teams, Parimal Bag, Nona Pepito
Double-Edged Transparency In Teams, Parimal Bag, Nona Pepito
Research Collection School Of Economics
In a team project with significant complementarities between various players' individual tasks, news of early success by some encourages others to push ahead with their own tasks while lack of success has the opposite effect. This ex-post disparity in incentives created gives rise to two differing implications, ex ante, for an ideal team transparency. Sometimes it is better to commit to complete secrecy within the team of the various participants' interim progress as it mitigates the negative effect of failures. In some other situations, commitment to full disclosure is better as players are then encouraged to be proactive by exerting …

Payroll Taxes, Wealth And Employment In Neoclassical Theory: Neutrality Or Nonneutrality?, Hian Teck Hoon
Research Collection School Of Economics
The theoretical proposition that temporarily below-normal tax rates on labor this year, when merged with the prospect of reversion to normal rates next year, will encourage households to squeeze more work into this year and to work less in future years is well-founded. This proposition was recently tested anew on Icelandic data and performed well empirically (Bianchi, Gudmundsson, and Zoega 2001). But would a permanent cut in tax rates on labor encourage more work permanently—with no diminution of effectiveness? Conversely, does a permanent increase in tax rates on labor cause a permanent decline in hours worked?
