Factors That Contribute to Becoming Unbanked

The proportion of US families that are unbanked (i.e., have no type of checking or savings account) has steadily declined for more than two decades. Nonetheless, more than nine million families still do not participate in the financial mainstream, and roughly half these unbanked families previously held a traditional bank account. This study uses the 2004 longitudinal Survey of Income Program Participation to examine the dynamic process within which changes in families' circumstances contribute to their becoming unbanked. Our findings suggest that families are significantly more likely to become unbanked when there is a decline in family income, loss of employment, or loss of health insurance coverage. Race and ethnicity, level of education or family income, and marital or housing status are also important determinants of whether families participate in the financial mainstream or not. To our knowledge, this is the first analysis of the dynamic process by which families change bank status.     

Discrimination Against Prounion Job Applicants

This study analyzes 95 unfair labor practices involving pre-employment discrimination against union adherents. The cases were heard either by the National Labor Relations Board or U.S. Court of Appeals between 1976 and 1986. Nonsupervisory, unskilled applicants who suffer preemployment discrimination by employers that display antiunion sentiments during union organizing campaigns have a lower probability of winning their cases than to skilled applicants. Pre-employment screening of job applications with prounion backgrounds or attitudes is often part of a larger pattern of unfair labor practices by management. The Dotson administration also supported management's rejection of prounion applicants at a significantly higher rate than did other NLRB administrations.     

Improving Productivity and Quality Through Collaboration

This study examines the impact of joint labor-management activities on perceived changes in productivity and quality, while controlling for the exercise of relative power options. Ordered probit estimates yield general support for the central proposition that the greater the intensity of joint activities, the greater the productivity and quality improvements. Mixed results are obtained regarding the impact of capital substitution, subcontracting, and concession bargaining on performance in collaborative settings.     

Labor Market Discrimination against Women with Disabilities

This article estimates the extent of wage discrimination and, for the first time, the employment effects of wage discrimination, against women with disabilities. In 1984, more than one-half of the offer wage differential between disabled and nondisabled women is attributable to discrimination, but the absolute wage differential is small. The results suggest that wage discrimination related to disability tends to be most severe for a relatively small group of women with impairments against which prejudice is most intense. There is a large difference between the employment rates of disabled and nondisabled women but only a small part of the differential is attributable to the disincentive effects of wage discrimination. The results also show that women with disabilities face a double burden of gender- and disability-related discrimination, but do not show that gender-related discrimination is worse for women who have a disability.     

Heteroskedasticity in Stock Returns

We use predictions of aggregate stock return variances from daily data to estimate time-varying monthly variances for size-ranked portfolios. We propose and estimate a single factor model of heteroskedasticity for portfolio returns. This model implies time-varying betas. Implications of heteroskedasticity and time-varying betas for tests of the capital asset pricing model (CAPM) are then documented. Accounting for heteroskedasticity increases the evidence that risk-adjusted returns are related to firm size. We also estimate a constant correlation model. Portfolio volatilities predicted by this model are similar to those predicted by more complex multivariate generalized-autoregressive-conditional-heteroskedasticity (GARCH) procedures.
