Persistent Advantage or Disadvantage?: Evidence in Support of the Intergenerational Drag Hypothesis

By utilizing the Integrated Public Use Microdata Series (IPUMS) and a measure of occupational prestige (OCCSCORE) as a labor market outcome, the authors examine variations in the degree of labor market discrimination faced by several ethnic and racial groups in the United States between 1880 and 1990. Results demonstrate that the sharpest decline in labor market discrimination against blacks occurred between 1960 and 1980. For black males the extent of labor market discrimination was greater in all census years in IPUMS after 1880 until 1970, evidence contradicting the conventional expectation that market-based discrimination will decline progressively over time by dint of competitive pressure. Finally, after replicating George Borjas' ethnic capital exercise, the authors pool the 1880, 1900, and 1910 data to determine the relative magnitude of a group's gains and losses in occupational prestige due to group advantage or disadvantage in human capital endowments and due to favorable or unfavorable treatment (nepotism or discrimination) of those endowments in the labor market. The authors then examine statistically whether the group human capital advantage or disadvantage and group exposure to nepotism or discrimination at the turn of the century affects labor market outcomes for their descendants today. Results indicate strong effects of the past on present labor market outcomes. Hence, the essence of the study is the statistical demonstration that there are significant and detectable effects on current generations of the labor market experiences of their racial/ethnic ancestors.     

Conceptualizing Professionalism

A bstract The main argument presented here is that economics provides a necessary but not sufficient analysis of professionalism. A sufficient analysis can only be generated by recognizing the sociological significance of professionals, and in particular the institutionalization of a professional ethic. In this way we suggest that economics needs sociology to provide an effective conceptualization of professionalism as a form of organization and as a mode of behavior. Equally, however, sociology needs economics, because while the sociological context provides an explanation of the way power is institutionalized, an economic focus is necessary to maintain a role for individual agency. These arguments are illustrated with a discussion of the historical and institutional complexities of professional organization; we look particularly at nursing and certain routinized areas of legal work and accountancy.     

Nixon’s desperate attempt to fight inflation

Because of continuing Inflation and rising unemployment, Americans were beginning to feel rather frustrated with the Nlxon Administration for their non-actions on the economic front. As an answer to this growing feeling of anxiety the US-President introduced an economic programme which has caused quite a stir in the USA as well as abroad. The author’s intent is to discuss the national and International effects the Nlxon programme will probably have.     

A simulation model for evaluating a set of emergency vehicle base locations: development, validation, and usage.

This paper describes our experiences in developing a simulation model for evaluating a set of emergency response vehicle base locations. The project was undertaken jointly by the University of Arizona and the Tucson Fire Department. The issues of model development, data collection, model validation, and experimentation are discussed. The critical nature of the problem and the clients' lack of experience with mathematical models, made model validation the major step in gaining user acceptance. We show that looking solely at standard performance statistics such as the calls successfully serviced, may lead to the acceptance of an invalid model. We also show that the high level of detail used in many simulation models for evaluating base locations is unnecessary in the current case. An analysis evaluating two alternative sets of locations for the Tucson system is discussed.
