A Nonparametric Poolability Test For Panel Data Models With Cross Section Dependence, Sainan Jin, Liangjun Su
Research Collection School Of Economics
In this article we propose a nonparametric test for poolability in large dimensional semiparametric panel data models with cross-section dependence based on the sieve estimation technique. To construct the test statistic, we only need to estimate the model under the alternative. We establish the asymptotic normal distributions of our test statistic under the null hypothesis of poolability and a sequence of local alternatives, and prove the consistency of our test. We also suggest a bootstrap method as an alternative way to obtain the critical values. A small set of Monte Carlo simulations indicate the test performs reasonably well in finite …

Does Child Sponsorship Have A Positive Impact On The Quality Of Life And Social Behavior Of Sponsored Children? Evidence From Indonesia, Mario Carrillo
Creative Activity and Research Day - CARD
Relaxing internal constraints of individuals at early stages of life is an approach that complements traditional policy interventions aimed to alleviate poverty. The Compassion International child sponsorship program focuses their work on the emotional, social, and spiritual development of sponsored children. This study uses age-eligibility as an instrument for sponsorship to investigate the impacts of child sponsorship on self-esteem, aspirational reference points, aspirational capital, reciprocity and patience. It also implements an innovative way of constructing summary indices using a method proposed by Anderson, M (2008). Results reveal child sponsorship does not have an effect on the sponsored children. In fact, …

An Econometric Analysis Of Anti-Bullying Program Factors On Bullying In Public American Middle Schools And High Schools, Austin B. Beck
Undergraduate Economic Review
This paper seeks to answer the question: “Do typical factors of anti-bullying programs reduce the amount of bullying that takes place in American public middle schools and high schools?” An overview of the literature on bullying and anti-bullying programs is provided. Data from the School Survey on Crime and Safety is analyzed using a probit model. The model is tested for accuracy and the results are analyzed. Parental involvement and out-of-school suspension are found to be significant anti-bullying program factors. Other explanatory variables are also discussed and recommendations for further research are provided.

Public Health Roi: Evidence, Experience And Remaining Questions, Glen P. Mays
Health Management and Policy Presentations
Expanding the delivery of efficacious public health and prevention strategies holds considerable potential for improving health outcomes and constraining costs across the U.S. health system. Unfortunately, lingering certainties about the costs required to expand public health delivery systems and about the health and economic effects of such expansions has muted private and public support for increased public health expenditures. This lecture examines recent evidence from public health services and systems research studies that examine the health and economic value of public health delivery, and identifies remaining research needs for the field.

The Existence Of State Dependence And Switching Costs In The Transition From Myspace To Facebook,

Scripps College
The Existence Of State Dependence And Switching Costs In The Transition From Myspace To Facebook, Taryn M. Ohashi
Scripps Senior Theses
In this paper, I examine the existence and roles of state dependence and switching costs in the mass transition from MySpace to Facebook during the 2007-2008 time period. Using a dataset that compiles individual browsing behavior and a discrete multinomial logit model, I find precise, yet extremely small amounts of state dependence for users of only MySpace, of only Facebook, and users of both MySpace and Facebook. Positive state dependence directly implies the existence of switching costs for each firm. While there is an abundance of literature regarding switching costs in the brick and mortar setting with tangible products and …

Tolls, Exchange Rates, And Northbound International Bridge Traffic: 1990-2006, Thomas M. Fullerton Jr., Angel L. Molina Jr., Adam G. Walke
Border Region Modeling Project
Although there have been a small number of empirical studies that analyze northbound border crossings between Mexico and the United States, very few examine the potential impacts of both tolls and exchange rates on the various traffic categories. This effort attempts to partially fill that gap in the applied economics literature by modeling northbound traffic flows at one of the largest regional economies along the border. Results indicate that business cycle fluctuations, variations in the real exchange rate, and changes in real toll tariffs all influence cross border traffic volumes. Tolls on northbound traffic into the United States are assessed …

Local Linear Gmm Estimation Of Functional Coefficient Iv Models With Application To The Estimation Of Rate Of Return To Schooling, Liangjun Su, Irina Murtazashvili, Aman Ullah
Research Collection School Of Economics
We consider the local linear GMM estimation of functional coe cient models with a mix of discrete and continuous data and in the presence of endogenous regressors. We establish the asymptotic normality of the estimator and derive the optimal instrumental variable that minimizes the asymptotic variance-covariance matrix among the class of all local linear GMM estimators. Data-dependent bandwidth sequences are also allowed for. We propose a nonparametric test for the constancy of the functional coefficients, study its asymptotic properties under the null hypothesis as well as a sequence of local alternatives and global alternatives, and propose a bootstrap version for …
Nonparametric Testing For Asymmetric Information,

Nonparametric Testing For Asymmetric Information, Liangjun Su, Martin Spindler
Research Collection School Of Economics
Asymmetric information is an important phenomenon in many markets and in particular in insurance markets. Testing for asymmetric information has become a very important issue in the literature in the last two decades. Almost all testing procedures that are used in empirical studies are parametric, which may yield misleading conclusions in the case of misspecification of either functional or distributional relationships among the variables of interest. Motivated by the literature on testing conditional independence, we propose a new nonparametric test for asymmetric information, which is applicable in a variety of situations. We demonstrate that the test works reasonably well through …

Testing Monotonicity In Unobservables With Panel Data, Liangjun Su, Stefan Hoderlein, Halbert White
Research Collection School Of Economics
Monotonicity in a scalar unobservable is a crucial identifying assumption for an important class of nonparametric structural models accommodating unobserved heterogeneity. Tests for this monotonicity have previously been unavailable. This paper proposes and analyzes tests for scalar monotonicity using panel data for structures with and without time-varying unobservables, either partially or fully nonseparable between observables and unobservables. Our nonparametric tests are computationally straightforward, have well behaved limiting distributions under the null, are consistent against precisely specified alternatives, and have standard local power properties. We provide straightforward bootstrap methods for inference. Some Monte Carlo experiments show that, for empirically relevant sample …

Collusion Set Detection Using A Quasi Hidden Markov Model, Zhengxiao Wu, Xiaoyu Wu
Research Collection School Of Economics
In stock market, a collusion set is defined as a group of individuals or organizations who act cooperatively with an intention of manipulating security price. Collusion-based malpractices impose large costs on the economy, but few techniques have yet been developed for collusion set detection. In this article, we propose a quasi hidden Markov model (QHMM) approach. In particular, we consider the transactions as a marked point process with hidden states, and we calculate the class conditional probabilities to identify the malicious transactions. The detection algorithms associated with the model are recursive, hence suitable for online monitoring and detection. The QHMM …

What Are The Effects Of Mergers In The U.S. Airline Industry? An Econometric Analysis On Delta-Northwest Merger, Jiajun Liang
The Macalester Review
The Delta-Northwest Merger in 2008 has significantly reshaped the airline market structure and raised public concerns regarding market dominance. In this study, I will employ OLS techniques to examine the effects of merger on airfares, using more than 1,000 observations from 2008 and 2009 airline markets. Results show the belief that unbalanced market share will lead to heightened airfares misleading and unreliable. There is no significant evidence suggesting positive or negative correlations between airport dominance and airfares.
