The peer effects literature has established that peers impact each other in the classroom through academic achievement and cognitive ability, but not explored many alternative channels. This paper examines how non-cognitive traits of an individual’s learning outcomes. I estimate a linear-in-means model models with additional terms accounting for “Big Five” personality traits. Controlling select...

Although each statistical unit on which measurements are taken is unique typically there is not enough information available to account totally for its uniqueness. Therefore heterogeneity among units has to be limited by structural assumptions. One classical approach is to use random effects models, which assume that heterogeneity can be described by distributional assumptions. However, inferen...

The “secondary effects” doctrine allows municipalities to zone, or otherwise regulate, sexually oriented businesses like strip clubs. Negative “secondary effects” (externalities) justify limiting First Amendment protection of speech conducted inside strip clubs. We utilize a repeat sales regression model of housing prices to estimate the causal effect of strip clubs on nearby residential proper...

Leg length discrepancy can be noticed commonly in the general population occurring naturally without any secondary side effects it also can be noticed in some patient after surgical treatment of fractures or joint replacement surgery. The presence of this discrepancy can be assessed clinically and can be precisely measured using imaging techniques. LLD can badly affect the lower back, pelvis, h...

Copyright © 1994, AAAI. 0738-4602-1994 / $2.00 ■ To integrate robotics into society, it is first necessary to measure and analyze current societal responses to areas within robotics. This article is the second in a continuing series of reports on the societal effects of various aspects of robotics. In my previous article, I discussed the problems of sensor abuse and outlined a program of treatm...

Meta-analysis is a standard statistical method used to combine the conclusions of individual studies that are related and the results of single study alone can not answered to deal with issues. The data are summarized by one or more outcome measure estimates along with their standard errors. The multivariate model and the variations between studies are not considered in most articles. Here we d...

This paper sheds some light on the problems associated with random effects gravity approaches. Arguments for the superiority of a fixed effects model are given both along intuitive and econometric lines based on a Hausman test.  2000 Elsevier Science S.A. All rights reserved.

This paper uses data drawn from the English Football League to model separate hazard rates for club managers for the 2001/2, 2002/3 and 2003/4 seasons. On average over the three seasons, approximately one-third of managers involuntarily exited employment status with their club. We model the hazard using a standard logistic model exploiting information on the spell at risk rather than the indivi...
