Factors influencing women's decision to leave an organization following childbirth

The purpose of this study was to understand the reasons why college-educated women leave organizations after childbirth. Results from 228 women who participated in a study of intention to work following childbirth indicated specific work and family factors that differentiated mothers who returned to work from mothers who stayed home after childbirth. Comparisons were also made between women who had a child and those who anticipated having a child. The findings are discussed in terms of their implications for organizational policy makers.     

Estimating Systematic Risk Using Time Varying Distributions

This article proposes a dynamic vector GARCH model for the estimation of time-varying betas. The model allows the conditional variances and the conditional covariance between individual portfolio returns and market portfolio returns to respond asymmetrically to past innovations depending on their sign. Covariances tend to be higher during market declines. There is substantial time variation in betas but the evidence on beta asymmetry is mixed. Specifically, in 50% of the cases betas are higher during market declines and for the remaining 50% the opposite is true. A time series analysis of estimated time varying betas reveals that they follow stationary mean-reverting processes. The average degree of persistence is approximately four days. It is also found that the static market model overstates non-market or, unsystematic risk by more than 10%. On the basis of an array of diagnostics it is confirmed that the vector GARCH model provides a richer framework for the analysis of the dynamics of systematic risk.
