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.

The transition from paid to self-employment in Canada: the importance of push factors
TL;DR: The authors found that longer spells of joblessness favour self-employment, workers who collect unemployment benefits between jobs are less likely to become self-employed than are workers who did not, and workers who left their previous, paid jobs involuntarily -i.e., due to layoff -were more likely than those who left voluntarily, but less likely than workers who specified personal reasons for leaving.

Can Habitat Protection Lead to Improvements in Human Well-Being? Evidence from Marine Protected Areas in the Philippines
TL;DR: In this paper, the authors analyzed data from 40 community-based marine protected areas in the Philippines to determine the correlates of win-win versus lose-lose or tradeoff outcomes, measured in terms of children's nutritional status and coral reef health.

The Effect of an Employer Health Insurance Mandate on Health Insurance Coverage and the Demand for Labor: Evidence from Hawaii
TL;DR: This paper examined the long term effects of the only employer health insurance mandate that has ever been enforced in the United States, Hawaii's Prepaid Health Care Act, using a standard supply-demand framework and Current Population Survey data covering the years 1979 to 2005.

Do Reimbursement Delays Discourage Medicaid Participation By Physicians
TL;DR: Examining how Medicaid reimbursement time affects physicians' willingness to accept Medicaid patients finds delays in reimbursement can offset the effects of high Medicaid fees, thereby lowering participation to levels that are closer to those in states with relatively low rates.

Explaining the Deteriorating Entry Earnings of Canada's Immigrant Cohorts, 1966-2000
TL;DR: This article explored the causes of the deterioration in entry earnings of successive cohorts of immigrant men and women, finding that roughly one-third of the degradation is explained by compositional shifts in language ability and region of birth.

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.

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.
