This study investigates the impact of information technology (IT) on productivity and collaboration patterns in academe. Our data combine information on the diffusion of two noteworthy innovations in IT--BITNET and the Domain Name System (DNS)--with career-history data on research-active life scientists. We analyzed a random sample of 3,114 research-active life scientists from 314 U.S. institutions over a 25-year period and find that the availability of BITNET on a scientist's campus has a positive effect on his or her productivity and collaborative network. Our findings also support the hypothesis of a differential effect of IT across subgroups of the scientific labor force. Women scientists and those working at nonelite institutions benefit more from the availability of IT in terms of overall research output and an increase in the number of new coauthors they work with than do men or individuals at elite institutions. These results suggest that IT is an equalizing force, providing a greater boost to productivity and more collaboration opportunities for scientists who are more marginally positioned in academe.diffusion, innovation, technology, life sciences, professional labor markets, gender

In what percentage of married couples do wives outearn their husbands, and, moreover, how persistent are these patterns? This study systematically examined variation in point-in-time estimates across alternative measures of earnings, definitions of types of couples, and data sources and gauged the persistence of these patterns for a period of three calendar years using data from the 2000 Current Population Survey and the 1996-2000 Survey of Income and Program Participation. Among the findings are that in 19% to 30% of all married couples, wives have higher earnings than their husbands. In 60% of such couples, this arrangement persists over the three-year period; for the rest, this arrangement is transitory.

We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit.
