This paper investigates the extent and ways in which childhood family and neighborhood quality influence later-life health outcomes. The study analyzes the health trajectories of children born between 1950 and 1970 followed through 2005. Data from the Panel Study of Income Dynamics (PSID) spanning four decades are linked with information on neighborhood attributes and school quality resources t...

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...

Thanks to advancements in smart mobile devices and social media platforms, sharing photos and experiences has significantly bridged the authors’ lives, allowing them to stay connected despite distance and other barriers. Most approaches to protect image visual privacy focus on encrypting or permuting image data, which generate unreadable image or highly distorted visual effect and therefore may...

This paper studies the quantitative importance of precautionary wealth accumulation relative to life—cycle saving for retirement. Section 1 examines panel data on earnings from the PSID. Using a bivariate normal model of random effects, we find that second— period—of—life earnings are strongly positively correlated with initial earnings but have a higher variance. Section 2 studies the conseque...

This paper examines, theoretically and empirically, the determinants of collective success in the maintenance of infrastructure projects. The empirical analysis employs primary data collected by the author on 132 community-maintained infrastructure projects in Northern Pakistan. Determinants are grouped into community-specific and project-specific factors, the latter identified using community ...

Despite the growing importance of interregional migration at the local level in rapidly aging society, past literature overlooked the relationship between these two demographic phenomena. To better understand the determinants of interregional migration and its implications for population aging, this study estimated fixed-effects models derived from the gravity model of migration using populatio...
