Black-White Segregation, Discrimination, and Home Ownership

The effect of discrimination on black-white racial segregation is studied using a confidential supplement of the Panel Study of Income Dynamics (PSID). Audit studies reveal that the rate of discrimination in rental housing is substantially higher than in owner-occupied housing. Thus, a variable indicating home ownership is used to proxy for the discrimination rate faced by blacks. The fixed-effects estimates of segregation imply that home ownership is associated with a decline in black-white segregation. This effect decreases slightly at higher income levels but increases substantially with the education of the head of household. Evidence is presented that the effect of discrimination on segregation disappears in cross-sectional data but reappears when using a panel and controlling for fixed-effects. The findings of this study suggest that increased government enforcement of fair housing laws may have a quantitatively different effect on different segments of society and that future research on racial segregation should emphasize the use of panel, as opposed to cross-sectional, data.housing, discrimination, segregation, DeRango

A Note on Commutes and the Spatial Mismatch Hypothesis

A number of empirical studies have tested the spatial mismatch hypothesis by examining the commuting times of blacks and whites. This note points out that the link between spatial mismatch and commuting times may be weak when employment probabilities decline as the distance from job site to residence increases. A simple spatial model of urban employment is developed in which a fixed number of agents live in the central city. Two examples are presented in which increased spatial mismatch may either increase or decrease the average commuting time of central city minorities, depending on the rate at which employment probabilities decline with distance.unemployment, insurance, compensation, older, workers, O'Leary, Wandner

Macromolecular Interactome of Tetrahymena CHD Family Chromatin Remodelers

Tetrahymena thermophila undergoes RNA-guided, DNA elimination during development. Bioinformatic and functional analyses on tChd family chromatin remodelers suggest the proteins are candidate DNA and RNA binding proteins. In vivo and in vitro functional analyses on tChd3 and tChd7 identified diverse macromolecular interactions throughout the lifecycle. Chd3 bound a novel protein named Miz1, which is a candidate E3 SUMO ligase. Chd3 and Miz1 co-localize to vegetatively repressed PDD1, and may regulate transcription via epigenetic SUMOylation of chromatin. Chd7 binds (un)modified H3K36, and highly transcribed genes during vegetative growth. This binding may regulate transcriptional turnover by Chd7-mediated reading of the acetyl/methyl status at H3K36. In vitro analyses suggest Chd7 binds poly(G) RNAs. G-rich sequences are transcribed during RNA-guided DNA elimination events, and Chd7 may be involved during this part of Tetrahymena development. These analyses provide a glimpse into how RNAs and epigenetics orchestrate chromatin dynamics, in complex eukaryotic regulatory mechanisms
