Does Child Sponsorship Have A Positive Impact On The Quality Of Life And Social Behavior Of Sponsored Children? Evidence From Indonesia, Mario Carrillo Apr 2013

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, …

Public Health Roi: Evidence, Experience And Remaining Questions, Glen P. Mays Apr 2013

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, Taryn M. Ohashi Apr 2013

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 Apr 2013

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 Apr 2013

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, Liangjun Su, Martin Spindler Apr 2013

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 Apr 2013

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 Apr 2013

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 Mar 2013

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.

Bias In The Mean Reversion Estimator In Continuous-Time Gaussian And Lévy Processes, Yong Bao, Aman Ullah, Yun Wang, Jun Yu Mar 2013

Bias In The Mean Reversion Estimator In Continuous-Time Gaussian And Lévy Processes, Yong Bao, Aman Ullah, Yun Wang, Jun Yu

Research Collection School Of Economics

Continuous-time Levy processes have become increasingly popular in the asset pricing literature and estimation of the mean reversion parameter has attracted attention recently. This paper develops the approximate nite-sample bias of the ordinary least squares or quasi maximum likelihood estimator of the mean reversion parameter in continuous-time Levy processes. Simulations show that in general the approximate bias works well in capturing the true bias of the mean reversion estimator under difference scenarios. However, when the time span is small and the mean reversion parameter is approaching its lower bound, we find it more difficult to approximate well the nite-sample bias.

Estimating The Health And Economic Effects Of Public Health Spending, Glen P. Mays Feb 2013

Estimating The Health And Economic Effects Of Public Health Spending, Glen P. Mays

Health Management and Policy Presentations

Preventable health conditions account for more than 75% of the $2.7 trillion spent annually on health care in the U.S., yet less than 5% of these expenditures are devoted to public health programs and services that are designed to prevent and control disease and injury rather than to treat the downstream consequences of these conditions. Such limited expenditures in public health may contribute to the higher rates of preventable morbidity, mortality and excess medical costs experienced in the U.S. compared to other high-income countries. In this presentation, I update previous estimates of the health effects and medical cost offsets associated …

Physical Infrastructure And Economic Growth In El Paso: 1976-2009, Thomas M. Fullerton Jr., Azucena González Monzón, Adam G. Walke Feb 2013

Physical Infrastructure And Economic Growth In El Paso: 1976-2009, Thomas M. Fullerton Jr., Azucena González Monzón, Adam G. Walke

Border Region Modeling Project

Prior research on the impacts of public capital stocks on economic growth has generally employed either national macroeconomic or multi-jurisdictional regional data. This study attempts to contribute to this area of the discipline by utilizing time series data for a single metropolitan economy. To allow for both short-run and long-run effects, an error correction modeling framework is used for the empirical analysis. Because comprehensive public infrastructure stocks are not published for El Paso, Texas, estimates for those variables are calculated using information regarding annual public capital investment data. Estimation results indicate that physical infrastructure investment may disrupt short-run economic growth, …

Standardized Lm Tests For Spatial Error Dependence In Linear Or Panel Regressions, Badi H. Baltagi, Zhenlin Yang Feb 2013

Standardized Lm Tests For Spatial Error Dependence In Linear Or Panel Regressions, Badi H. Baltagi, Zhenlin Yang

Research Collection School Of Economics

The robustness of the Lagrange Multiplier (LM) tests for spatial error dependence of Burridge (1980) and Born and Breitung (2011) for the linear regression model, and Anselin (1988) and Debarsy and Etur (2010) for the panel regression model with random or fixed effects are examined. While all tests are asymptotically robust against distributional mis‐specification, their finite sample behaviour may be sensitive to the spatial layout. To overcome this shortcoming, standardized LM tests are suggested. Monte Carlo results show that the new tests possess good finite sample properties. An important observation made throughout this study is that the LM tests for …

A Nonparametric Goodness-Of-Fit-Based Test For Conditional Heteroskedasticity, Liangjun Su, Aman Ullah Feb 2013

A Nonparametric Goodness-Of-Fit-Based Test For Conditional Heteroskedasticity, Liangjun Su, Aman Ullah

Research Collection School Of Economics

In this paper we propose a new nonparametric test for conditional heteroskedasticity based on a measure of nonparametric goodness-of-fit (R2) that is obtained from the local polynomial regression of the residuals from a parametric regression on some covariates. We show that after being appropriately standardized, the nonparametric R2 is asymptotically normally distributed under the null hypothesis and a sequence of Pitman local alternatives. We also prove the consistency of the test and propose a bootstrap method to obtain the bootstrap p-values. We conduct a small set of simulations and compare our test with some popular parametric and nonparametric tests in …

The Relationship Between Inequality And Economic Growth: Evidence From Latin America, Amanda Gallagher Jan 2013

The Relationship Between Inequality And Economic Growth: Evidence From Latin America, Amanda Gallagher

Empirical Economic Bulletin, An Undergraduate Journal

This paper investigates the complex relationship between income inequality and economic growth in the Latin American region. This study conducts an empirical analysis using economic growth as the dependent variable, to determine the impact inequality has on economic growth. This study uses panel data from countries in Latin America over the time period of 1994-2009. The empirical results show a negative relationship between inequality and economic growth in the Latin American region. In addition, the level of government expenditure and taxation in the countries impact economic growth.
