This paper investigates the responsiveness of individuals’ retirement decisions to forward-looking measures of pension accumulations. In contrast to previous research, we use within-person variation in retirement incentives and are able to control for unobserved heterogeneity in tastes for retirement by studying a panel of subjective retirement expectations. We confirm that individuals do respo...

Objective. To pilot test an artificial intelligence (AI) algorithm that selects peer change agents (PCA) to disseminate HIV testing messaging in a population of homeless youth. Methods. We recruited and assessed 62 youth at baseline, 1 month (n = 48), and 3 months (n = 38). A Facebook app collected preliminary social network data. Eleven PCAs selected by AI attended a 1-day training and 7 weekl...

Genotypes may influence the phenotypic associations among IQ, education, and income. To investigate this hypothesis, we believe that the appropriate methodology requires estimation of genetic and environmental influences using data able to separate these influences. The National Longitudinal Survey of Youth (NLSY) is a nationally representative sample that contains genetically-informative fulla...

Research conclusions in the social sciences are increasingly based on meta-analysis, making questions of the accuracy of meta-analysis critical to the integrity of the base of cumulative knowledge. Both fixed effects (FE) and random effects (RE) meta-analysis models have been used widely in published meta-analyses. This article shows that FE models typically manifest a substantial Type I bias i...

This paper uses a linked employer-employee dataset from the Ghanaian manufacturing sector to analyze earnings dispersion in Ghana from 1992 to 2003, a period post extensive economic reforms. I find that variance of earnings increased from 1992 to 1998 and decreased thereafter, resembling an inverted u-shaped relationship. I use analysis of variance and variance decomposition approaches to under...

Decompositions by population subgroups and by income sources represent the traditional techniques for decomposing income inequality. Compared with the classical methodologies, the regression-based method gives the opportunity of quantifying the contribution to the inequality of a set of factors, while taking the correlations among them into account. In this framework, two regression-based decom...
