TLDR
The authors illustrates the danger of spurious regression from this kind of misspecification, using as an example a wage regression estimated on data for individual workers that includes in the specification aggregate regressors for characteristics of geographical states.Abstract:
Many economic researchers have attempted to measure the effect of aggregate market or public policy variables on micro units by merging aggregate data with micro observations by industry, occupation, or geographical location, then using multiple regression or similar statistical models to measure the effect of the aggregate variable on the micro units. The methods are usually based upon the assumption of independent disturbances, which is typically not appropriate for data from populations with grouped structure. Incorrectly using ordinary least squares can lead to standard errors that are seriously biased downward. This note illustrates the danger of spurious regression from this kind of misspecification, using as an example a wage regression estimated on data for individual workers that includes in the specification aggregate regressors for characteristics of geographical states.

Do charter schools skim students or drain resources
Thomas S. Dee,Helen Fu +1 more
TL;DR: The authors found that the introduction of charters in Arizona has increased pupil-teacher ratios in traditional public schools by 6 percent and reduced the proportion of white non-Hispanic students by 2 percent.
The Effects of Institutional Factors on the Success of Community College Students
TL;DR: In this paper, the authors presented a research project, conducted by the Community College Research Center (CCRC) and one component of a Ford Foundation-funded study on minority degree attainment at community colleges, which used institution level data to analyze the effect of community college characteristics on student performance.

The Effect of Crime on Life Satisfaction
Mark A. Cohen,Mark A. Cohen +1 more
TL;DR: This article found that while being burglarized has a large and significant effect on a victim's overall life satisfaction, neither county-level crime rates nor neighborhood safety appear to have very large impacts on daily life satisfaction to the average American.
Are voters better informed when they have a larger say in politics
Matthias Benz,Alois Stutzer +1 more
TL;DR: This paper used a large survey from Switzerland to find evidence that citizens are politically better informed when they have more extended participation rights in the political process, which corroborates theoretical arguments and circumstantial evidence that voter information should be treated as endogenously determined by political institutions.

The cost of fear: shadow pricing the intangible costs of crime
TL;DR: In this article, a cross-sectional crime survey of UK residents was employed to estimate the shadow price of victimization with respect to fear of crime, focusing on the relationship between household income and crime.

TL;DR: The Elements of Econometrics as mentioned in this paper is a textbook for upper-level undergraduate and master's degree courses and may usefully serve as a supplement for traditional Ph.D. courses in economics.
Book
Elements of econometrics
TL;DR: The emphasis is on simplification whenever possible, assuming the readers know college algebra and basic calculus, and Jan Kmenta explains all methods within the simplest framework, and generalizations are presented as logical extensions of simple cases.

Maximum Likelihood Approaches to Variance Component Estimation and to Related Problems
TL;DR: In this paper, the authors proposed a restricted maximum likelihood (reml) approach which takes into account the loss in degrees of freedom resulting from estimating fixed effects, and developed a satisfactory asymptotic theory for estimators of variance components.
Journal ArticleDOI
Random group effects and the precision of regression estimates
TL;DR: The authors analyzes several empirical examples to investigate the applicability of random effects models and the consequences of inappropriately using ordinary least squares (OLS) estimation in the presence of random group effects.
