Essays In The Economics Of Education, Breyon J. Williams

Theses and Dissertations

I examine, separately, the impact of three education programs on student achievement, using difference-in-differences and difference-in-difference-in-differences designs. First, I examine whether spillover benefits on achievement exist from preschool. I estimate the effect of exposure to a South Carolina preschool program that targets disadvantaged four-year-olds on students’ test scores in grades 3 through 5, where exposure means residing in a school district once the program was made available and disadvantaged students are those eligible for free or reduced-price lunch or Medicaid. I find that exposure to the preschool program not only increases the math and reading scores of targeted students, but …

Analyzing Unemployment, Education-Occupation Mismatch, And Immigrant’S Participation In The Us Labor Market, Riyadh Naeem Arooq Arooq

Dissertations

Analyzing the factors that determine any labor market’s outcomes is important. That is because the results of these analyses can help policy makers to adopt effective labor market policies, and thus achieve the best outcomes of that labor market. In this study, I analyze three important factors: unemployment, education-occupation mismatch, and immigrants’ participation in the US labor market.

First, I analyze the problem of slow decline in the rate of U.S. unemployment after the last recessions. In this chapter, I examine whether the slow movement in U.S. unemployment is due to cyclical or structural factors. I contribute to the literature …

The Evolution Of State Higher Education Public Funding Policy, Angela Rogers

Senior Theses

In the past several decades, public colleges and universities have increasingly struggled to fund all of the programs demanded of them as states slowly drain funding from their coffers. This discussion will examine different policies and frameworks that have been used by states to determine funding for their public institutions. Different factors that will be considered include political relationships, governance structures, and accountability models. The political trend of “free college” will also be considered. Then, the discussion will narrow to South Carolina funding policy, how it has changed over the years, and what the current challenges are. A policy proposal …

Examining Grad Plus: Value And Cost, Accesslex Institute

AccessLex Institute Research

This report, the first in a two-part series, uses federal data to show that the primary criticisms of the Grad PLUS program—rising institutional education costs and potential cost to the federal government—are either nonexistent or massively overblown.

Random Coefficient Continuous Systems: Testing For Extreme Sample Path Behavior, Yubo Tao, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper studies a continuous time dynamic system with a random persistence parameter. The exact discrete time representation is obtained and related to several discrete time random coefficient models currently in the literature. The model distinguishes various forms of unstable and explosive behavior according to specific regions of the parameter space that open up the potential for testing these forms of extreme behavior. A two-stage approach that employs realized volatility is proposed for the continuous system estimation, asymptotic theory is developed, and test statistics to identify the different forms of extreme sample path behavior are proposed. Simulations show that the …

Common Threshold In Quantile Regressions With An Application To Pricing For Reputation, Liangjun Su, Pai Xu

Research Collection School Of Economics

The paper develops a systematic estimation and inference procedure for quantile regression models where there may exist a common threshold effect across different quantile indices. We first propose a sup-Wald test for the existence of a threshold effect, and then study the asymptotic properties of the estimators in a threshold quantile regression model under the shrinking-threshold-effect framework. We consider several tests for the presence of a common threshold value across different quantile indices and obtain their limiting distributions. We apply our methodology to study the pricing strategy for reputation via the use of a dataset from Taobao.com. In our economic …

Asymptotic Theory For Rough Fractional Vasicek Models, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper extends the asymptotic theory for the fractional Vasicek model developed in Xiao and Yu (2018) from the case where H ∈ (1/2, 1) to the case where H ∈ (0, 1/2). It is found that the asymptotic theory of the persistence parameter (k) critically depends on the sign of k. Moreover, if k > 0, the asymptotic distribution for the estimator of k is different when H ∈ (0, 1/2) from that when H ∈ (1/2, 1).

Rank Tests At Jump Events, Jia Li, Viktor Todorov, George Tauchen, Huidi. Lin

Research Collection School Of Economics

We propose a test for the rank of a cross-section of processes at a set of jump events. The jump events are either specific known times or are random and associated with jumps of some process. The test is formed from discretely sampled data on a fixed time interval with asymptotically shrinking mesh. In the first step, we form nonparametric estimates of the jump events via thresholding techniques. We then compute the eigenvalues of the outer product of the cross-section of increments at the identified jump events. The test for rank r is based on the asymptotic behavior of the …

Sieve Estimation Of Time-Varying Panel Data Models With Latent Structures, Liangjun Su, Xia Wang, Sainan Jin

Research Collection School Of Economics

We propose a heterogeneous time-varying panel data model with a latent group structure that allows the coefficients to vary over both individuals and time. We assume that the coefficients change smoothly over time and form different unobserved groups. When treated as smooth functions of time, the individual functional coefficients are heterogeneous across groups but homogeneous within a group. We propose a penalized-sieve-estimation-based classifier-Lasso (C-Lasso) procedure to identify the individuals’ membership and to estimate the group-specific functional coefficients in a single step. The classification exhibits the desirable property of uniform consistency. The C-Lasso estimators and their post-Lasso versions achieve the oracle …

Building An Equitable And Inclusive City Through Housing Policies: Singapore’S Experience, Sock Yong Phang

Research Collection School Of Economics

Inequality is an age-old concern. In recent years, the rise of income inequality has received worldwide media and policy attention, beginning with the Occupy movement of 2011-2012 and a wave of notable scholastic books such as Stiglitz (2012), Piketty (2014), and Atkinson (2015). Piketty’s Capital in the 21st Century, an unlikely bestseller, contained a vast amount of data showing that the rich are taking rising shares of income and wealth in the advanced economies. Piketty’s approach towards capital and wealth is an aggregative one, and he does not treat real estate or land as a different or distinct form of …

Illusion Of Gender Parity In Education: Intrahousehold Resource Allocation In Bangladesh, Sijia Xu, Abu S. Shonchoy, Tomoki Fujii

Research Collection School Of Economics

A target in the Millennium Development Goals—gender parity in all levels of education—is widely considered to have been attained. However, measuring gender parity only through school enrollment is misleading, as girls may lag behind boys in other educational measures. We investigate this with four rounds of surveys from Bangladesh by decomposing households’ education decisions into enrollment, education expenditure, and share of the education expenditure allocated for the quality of education like private tutoring. We find a strong profemale bias in school enrollment but promale bias in the other two decisions. This contradirectional gender bias is unique to Bangladesh and partly …

Robustly Optimal Reserve Price, Wei He, Jiangtao Li

Research Collection School Of Economics

We study a robust version of the single-unit auction problem. The auctioneer has confidence in her estimate of the marginal distribution of a generic bidder's valuation, but does not have reliable information about the joint distribution. In this setting, we analyze the performance of second-price auctions with reserve prices in terms of revenue guarantee, that is, the greatest lower bound of revenue across all joint distributions that are consistent with the marginals. For any finite number of bidders, we solve for the robustly optimal reserve price that generates the highest revenue guarantee. Our analysis has interesting implications in large markets. …

Weak Σ-Convergence: Theory And Applications, Jianning Kong, Peter C. B. Phillips, Donggyu Sul

Research Collection School Of Economics

The concept of relative convergence, which requires the ratio of two time series to converge to unity in the long run, explains convergent behavior when series share commonly divergent stochastic or deterministic trend components. Relative convergence of this type does not necessarily hold when series share common time decay patterns measured by evaporating rather than divergent trend behavior. To capture convergent behavior in panel data that do not involve stochastic or divergent deterministic trends, we introduce the notion of weak σ-convergence, whereby cross section variation in the panel decreases over time. The paper formalizes this concept and proposes a simple-to-implement …

Inference In Partially Identified Panel Data Models With Interactive Fixed Effects, Shengjie Hong, Liangjun Su, Yaqi Wang

Research Collection School Of Economics

This paper develops methods for statistical inferences in a partially identified nonparametric panel data model with endogeneity and interactive fixed effects. We consider the case where the number of cross-sectional units (N) is large and the number of time series periods (T).as well as the number of unobserved common factors (R) are fixed. Under some normalization rules, wecan concentrateout thelarge dimen-sional parameter vector of factor loadings and specify a set of conditional moment restriction that are involved with only the finite dimensional factor parameters along with the infinite dimensional nonpara-metric component. For a conjectured restriction on the parameter, we consider …

M-Estimators Of U-Processes With A Change-Point Due To A Covariate Threshold, Lili Tan, Yichong Zhang

Research Collection School Of Economics

Economic theory often predicts a “tipping point” effect due to multiple equilibria. Linear threshold regressions estimate the “tipping point” by assuming at the same time that the response variable is linear in an index of covariates. However, economic theory rarely imposes a specific functional form, but rather predicts a monotonic relationship between the response variable and the index. We propose new, rank-based, estimators for both the “tipping point” and other regression coefficients, exploiting only the monotonicity condition. We derive the asymptotic properties of these estimators by establishing a more general result for M-estimators of U-processes with a change-point due to …
