A demand model was developed and applied to a nationally representative sample of unmarried, pregnant teenagers drawn from the National Longitudinal Surveys in order to identify the economic determinants of abortion Measures of the opportunity costs of pregnancy were found to play a major role in the individual's decision to give birth or to abort Economic variables in the analysis included predicted wages, local area unemployment rates, other family income, poverty status, and school enrollment status Other factors found to be significant were age, ethnicity, and religiosity In general, young women in favorable economic circumstances were substantially more likely than others to abort a pregnancy
We examine the effect of unionization on police productivity in large U.S. metropolitan areas. We define police output in the context of a production function model that draws also on the crime literature. We estimate the resulting model using a data set that includes published and unpublished government statistics as well as our own survey of police departments. Results suggest that the effect of unions on police productivity varies according to categories of police performance. In particular, if performance is stratified according to the severity of crimes, unions seem to have an insignificant effect on police productivity with respect to serious crimes. For minor crimes, unionization alters the parameters of police production function, leading to diminished productivity.
Using datafrom the Bureau of Labor Statistics: Historical File, a model of wildcat strike incidence is estimated. The model supports the hypothesis that the incidence of wildcat strikes is related to the underlying relationship between the parties. In addition, national economic and political trends, industry-specific factors, and firm-specific factors have an impact on strike activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
