Effect Of Measurement Errors On The Separate And Combined Ratio And Product Estimators In Stratified Random Sampling, Housila P. Singh, Namrata Karpe Nov 2010

Effect Of Measurement Errors On The Separate And Combined Ratio And Product Estimators In Stratified Random Sampling, Housila P. Singh, Namrata Karpe

Journal of Modern Applied Statistical Methods

Separate and combined ratio, product and difference estimators are introduced for population mean μY of a study variable Y using auxiliary variable X in stratified sampling when the observations are contaminated with measurement errors. The bias and mean squared error of the proposed estimators have been derived under large sample approximation and their properties are analyzed. Generalized versions of these estimators are given along with their properties.

Labor And Media: A Strained Relationship, Mac-Z Zurawski Oct 2010

Labor And Media: A Strained Relationship, Mac-Z Zurawski

All Student Theses

The labor movement or union community of America has been in a steady decline for more than a decade. The 1950s saw the pinnacle of success with one-third of the U.S. workforce being unionized. Today only 8% of the private workforce is unionized. One way in which this decline may be perceived as more pronounced is through media alienation. According to journalists across the nation such as Philip M.Dine unions have been alienated by media and its type of union coverage. In this study, I analyze the way in which the New York Times portrays the labor movement during the …

Do Judges Vary In Their Treatment Of Race?, David S. Abrams, Marianne Bertrand, Sendhil Mullainathan Sep 2010

Do Judges Vary In Their Treatment Of Race?, David S. Abrams, Marianne Bertrand, Sendhil Mullainathan

All Faculty Scholarship

Are minorities treated differently by the legal system? Systematic racial differences in case characteristics, many unobservable, make this a difficult question to answer directly. In this paper, we estimate whether judges differ from each other in how they sentence minorities, avoiding potential bias from unobservable case characteristics by exploiting the random assignment of cases to judges. We measure the between-judge variation in the difference in incarceration rates and sentence lengths between African-American and White defendants. We perform a Monte Carlo simulation in order to explicitly construct the appropriate counterfactual, where race does not influence judicial sentencing. In our data set, …

Alternative Technical Efficiency Measures: Skew, Bias And Scale, Qu Feng, William C. Horrace Jun 2010

Alternative Technical Efficiency Measures: Skew, Bias And Scale, Qu Feng, William C. Horrace

Economics - All Scholarship

In the fixed-effects stochastic frontier model an efficiency measure relative to the best firm in the sample is universally employed. This paper considers a new measure relative to the worst firm in the sample. We find that estimates of this measure have smaller bias than those of the traditional measure when the sample consists of many firms near the efficient frontier. Moreover, a two-sided measure relative to both the best and the worst firms is proposed. Simulations suggest that the new measures may be preferred depending on the skewness of the inefficiency distribution and the scale of efficiency differences.

Estimating Hypothetical Bias In Economically Emergent Africa: A Generic Public Good Experiment, Arthur J. Caplan, David Aadland, Anthony Macharia Jan 2010

Estimating Hypothetical Bias In Economically Emergent Africa: A Generic Public Good Experiment, Arthur J. Caplan, David Aadland, Anthony Macharia

Applied Economics Faculty Publications

This paper reports results from a contingent valuation based public good experiment conducted in the African nation of Botswana. In a sample of university students, we find evidence that stated willingness to contribute to a public good in a hypothetical setting is higher than actual contribution levels. However, results from regression analysis suggest that this is true only in the second round of the experiment, when participants making actual contributions have learned to significantly lower their contribution levels. As globalization expands markets, and economies such as Botswana's continue to modernize, there is a growing need to understand how hypothetical bias …

The Paradox Of Emotionality & Competence In Multicultural Competency Training: A Grounded Theory, Jude A. Bergkamp Jan 2010

The Paradox Of Emotionality & Competence In Multicultural Competency Training: A Grounded Theory, Jude A. Bergkamp

Antioch University Dissertations & Theses

The American Psychological Association mandates multicultural competency training as a requirement of accredited doctoral programs. The tripartite model of knowledge, skills, and awareness has been the most consistently cited framework in the last two decades. Although multiple pedagogical methods have been researched, there has yet to be a unified theory developed to link educational techniques to the tripartite domain competencies. Furthermore, there is a dearth of research exploring the various learning factors involved in multicultural competency training. Emotionality is an important factor in obtaining multicultural competency. No unified theory of multicultural education can be developed without incorporating the element of …
