We measure sources of racial inequality in stockbroker pay. Pay differences arise from sales differences. We measure the extent to which sales differences are due to performance‐support bias, whereby African American brokers receive weaker firm supports, or to forces outside the firm, including client access, selection, and consumer discrimination. Data on firm policies are matched to sales results. Data on self‐generation of accounts measure access to wealthy clients. Sales generated from accounts with sales histories show racial differences in sales arising from selection or consumer discrimination.

We examine temporary workers (temps), their choices, and growth in temporary employment. We find that some people choose a temporary job because they desire greater schedule flexibility, particularly students and women with children. For most, however, weaker permanent job opportunities drive them into temporary positions. Using the 1995 and 1997 Current Population Surveys (CPS) we find that both the percentage of the work force in temporary jobs and the absolute number of temps declined when applying a new CPS-based measure of temporary. This is in stark contrast to the rising percentage found in several previous studies when looking only at workers in personnel supply services and clearly questions prior claims and concerns about growth in the temporary work force.

BackgroundThe Fox gene family comprises a large and functionally diverse group offorkhead-related transcriptional regulators, many of which are essential for metazoan embryogenesis and physiology. Defining conserved functional domains that mediate the transcriptional activity of Fox proteins will contribute to a comprehensive understanding of the biological function of Fox family genes.ResultsSystematic analysis of 458 protein sequences of the metazoan Fox family was performed to identify the presence of the engrailed homology-1 motif (eh1), a motif known to mediate physical interaction with transcriptional corepressors of the TLE/Groucho family. Greater than 50% of Fox proteins contain sequences with high similarity to the eh1 motif, including ten of the nineteen Fox subclasses (A, B, C, D, E, G, H, I, L, and Q) and Fox proteins of early divergent species such as marine sponge. The eh1 motif is not detected in Fox proteins of the F, J, K, M, N, O, P, R and S subclasses, or in yeast Fox proteins. The eh1-like motifs are positioned C-terminal to the winged helix DNA-binding domain in all subclasses except for FoxG proteins, which have an N-terminal motif. Two similar eh1-like motifs are found in the zebrafish FoxQ1 and in FoxG proteins of sea urchin and amphioxus. The identification of eh1-like motifs by manual sequence alignment was validated by statistical analyses of the Swiss protein database, confirming a high frequency of occurrence of eh1-like sequences in Fox family proteins. Structural predictions suggest that the majority of identified eh1-like motifs are short α-helices, and wheel modeling revealed an amphipathicity that supports this secondary structure prediction.ConclusionA search for eh1 Groucho interaction motifs in the Fox gene family has identified eh1-like sequences in greater than 50% of Fox proteins. The results predict a physical and functional interaction of TLE/Groucho corepressors with many members of the Fox family of transcriptional regulators. Given the functional importance of the eh1 motif in transcriptional regulation, our annotation of this motif in the Fox gene family will facilitate further study of the diverse transcriptional and regulatory roles of Fox family proteins.
