How Federal Pollution Discharge Permits Affect U.S. Water Quality: A Study On Concentrated Animal Feeding Operations, Cloe C. Mueller Aug 2022

How Federal Pollution Discharge Permits Affect U.S. Water Quality: A Study On Concentrated Animal Feeding Operations, Cloe C. Mueller

Theses and Dissertations

This paper uses difference-in-difference regression models to examine how state-level pollution discharge permits on concentrated animal feeding operations affect U.S. water quality. I ultimately deem the permitting to be ineffective at improving water quality, calling attention to the need to re-evaluate the ``socially optimal level of pollution."


Top Of The Order: Modeling The Optimal Locations Of Minor League Baseball Teams, W. Coleman Conley Nov 2014

Top Of The Order: Modeling The Optimal Locations Of Minor League Baseball Teams, W. Coleman Conley

Undergraduate Economic Review

Over the last twenty-five years, minor league baseball franchises have defined firm mobility. Revisiting the work of Michael C. Davis (2006), I construct a logistic regression model to predict which cities house minor league baseball teams. Six variables are tested for inclusion in the model, including population, income level, the number of major-league professional sports teams in a city, five-year population change, and distance from the closest professional team. Based on the model's predicted probabilities, cities are ranked in order of highest probability of having a team at each of the different levels from Class A to Class AAA.


Application Of Sgt Family Distributions In Quasi Maximum Likelihood Estimation, Samuel Dodini Oct 2013

Application Of Sgt Family Distributions In Quasi Maximum Likelihood Estimation, Samuel Dodini

Undergraduate Economic Review

In the classical normal linear regression model, ordinary least squares estimators (OLS) will be consistent and achieve the Cramer-Rao lower bound for any unbiased estimators. This paper examines the impact of several other error distributions on the properties of the OLS estimators. Several different types of example data commonly available to students and researchers in economics are used to illustrate the impact of nonnormality, because, in application, the assumption of normality may not hold in empirical testing. Using maximum likelihood, I demonstrate that flexible probability density functions better model the residual distribution of different types of data, which suggests improvements …


Regression Anatomy, Revealed, Valerio Filoso Jan 2011

Regression Anatomy, Revealed, Valerio Filoso

Valerio Filoso

The Regression Anatomy (RA) theorem (Angrist and Pischke 2009) is an alternative formulation of the Frisch-Waugh-Lovell (FWL) theorem (Frisch and Waugh 1933; Lovell 1963), a key finding in the algebra of OLS multiple regression models. In this paper, we present a command, reganat, to implement graphically the method of RA. This addition complements the built-in Stata command avplot in the validation of linear models, producing bidimensional scatterplots and regression lines obtained controlling for the other covariates, along with sev- eral fine-tuning options. Moreover, the article provides (1) a fully worked-out proof of the RA theorem and (2) an explanation of …
