Unions and wage inequality

Summary and Conclusions The impact of unions on the structure of wages has recently attracted renewed interest as analysts have struggled to explain the rise in earnings inequality in several industrialized countries. Canada, the United Kingdom, and the United States provide a potentially valuable set of countries for examining this question. All three countries now collect comparable data on wages and union status in their regular labor force surveys. Several features of the collective bargaining institutions of these countries make them suitable for studying the relationship between unions and wage inequality. Bargaining is highly decentralized; there are no general mechanisms for extending collective bargaining provisions beyond the “organized” sector; and the fraction of the work force covered by collective bargaining is relatively modest. Thus it is possible to compare the structure of wages for workers covered by union contracts to those who are not covered, and potentially infer the effect of unions on overall wage inequality.     

Courting LULUs: Characteristics of Suitor and Objector Communities*

Abstract This research examines nonmetropolitan places most likely to support or oppose proposals for locally undesirable land uses (LULUs) involving waste management facilities. Two hypotheses are tested: (1) that relatively remote communities of lower socioeconomic status will be less likely to oppose such proposals; and (2) that support for such proposals is widespread among nonmetropolitan communities because of growth machine activities. Using key informants and secondary data for 166 non‐metropolitan Pennsylvania places, we find that local growth promotion, especially efforts to promote business and industry, is related positively to community experience with plant closings and to proposals for these LULUs. Where these proposals are made, community opposition tends to be present as well, particularly in larger communities and, surprisingly, in those of lower socioeconomic status. The significance of these findings is discussed in terms of the growth machine and the opposition they can provoke to protect the use value of land in a single nonmetropolitan region.     

The Road to Gang Membership: Characteristics of Male Gang and Nongang Members from Ages 10 to 14

This study examined the stability of belonging to a gang in early adolescence, the behaviour profiles, family characteristics, and friendships of nongang and gang members. The subjects in the present study were originally part of a larger sample of boys. One hundred and forty‐two boys who had a complete data set at ages 11, 12, 13, and 14 were selected for the present study. Loglinear analyses indicated that gang membership was stable from ages 13 to 14, but not at earlier ages. Boys were divided into three groups: stable gang members (children who belonged to a gang at ages 13 and 14); unstable gang members (children who belonged to a gang at either age 13 or 14) and nongang members. Repeated analyses of variance indicated that stable gang members had significantly higher scores than nongang members on teacher ratings of fighting behaviour, hyperactivity, inattention and oppositional behaviour, and self‐reported delinquent activities (drug and alcohol use, stealing and vandalism). Peers rated gang members as more aggressive than nongang members. The results are discussed from a developmental perspective.     

Comment

A vector autoregression is a reduced-form representation and therefore would be expected to change when any structural equation in the system changes, regardless of whether economic decisions are forward-looking. Even so, a dynamic simulation of a model with unit roots will exhibit large cumulative errors, making it difficult to detect whether a structural change has indeed occurred.     

Empowering Lesbian,Gay, Bisexual,and Transgender Youth: Lessons Learned From a Safe Schools Summit

ABSTRACT

The bullying of lesbian, gay, bisexual, and transgender (LGBT) youth in schools is a significant problem in the United States. This study examined responses of youth participants at a statewide Safe Schools Summit to a survey of their experiences with school-based violence, harassment, and discrimination, and of the effects of their attendance at the Summit. Quantitative analyses found that 92% of respondents felt “more empowered” following participation in the Summit. Qualitative analyses found several emerging themes related to respondents' experiences with victimization (leading to a sense of powerlessness and attempts at self-protection) and to their experiences at the Summit itself (leading to catharsis, strengthened skills, and a commitment to confront bullies and to make schools safer). A conceptual model of the interaction of these factors is presented and implications for further research and practice are discussed.     

The Function of Credibility in Information Processing for Risk Perception

This study examines how credibility affects the way people process information and how they subsequently perceive risk. Three conceptual areas are brought together in this analysis: the psychometric model of risk perception, Eagly and Chaiken's heuristic-systematic information processing model, and Meyer's credibility index. Data come from a study of risk communication in the circumstance of state health department investigations of suspected cancer clusters (five cases, N = 696). Credibility is assessed for three information sources: state health departments, citizen groups, and industries involved in each case. Higher credibility for industry and the state directly predicts lower risk perception, whereas high credibility for citizen groups predicts greater risk perception. A path model shows that perceiving high credibility for industry and state-and perceiving low credibility for citizen groups-promotes heuristic processing, which in turn is a strong predictor of lower risk perception. Alternately, perceiving industry and the state to have low credibility also promotes greater systematic processing, which consistently leads to perception of greater risk. Between a one-fifth and one-third of the effect of credibility on risk perception is shown to be indirectly transmitted through information processing.     

Noisy Winter: The DDT Controversy in the Years before Silent Spring

Abstract In this paper, we examine three unanticipated findings from a social constructionist analysis of popular media coverage of the pesticide DDT from the years 1944 to 1961. The first unanticipated finding was the early (1945) appearance of negative or cautionary claims in the media source examined, the New York Times. Second, while negative or cautionary claims about the pesticide did constitute a minority voice during this time period, it was nonetheless a persistent voice. The third unanticipated finding was the predominance of the U.S. Department of Agriculture, and the State Agricultural Experiment Stations among those claimsmakers initially cautioning potential users about unintended and potentially deleterious impacts. The concept of "routine monitoring mechanisms" is introduced to explain this third finding. We conclude by considering the potential impact of this coverage on the subsequent development of the controversy.     

A Case Study on the Informational Efficiency of Markets: The Market for Horse Racing in Australia

This paper describes a study of the informational efficiency of the thoroughbred horse racing market in Australia. It is based on the theory of stock market efficiency which explains the process by which information becomes reflected in share prices. In this paper, the theory is applied to the thoroughbred horse racing market to determine the predictive accuracy of alternative informative sources. The results obtained from the study are consistent with the underlying theory:(i) aggregated information (as reflected in a consensus of opinions) is a more accurate prediction of success than less information (as reflected in individual opinions), and;(ii) the most recent information (as reflected in race-time betting odds, known as starting prices) has greater predictive ability than less recent information (as reflected in an earlier consensus of opinions).The study examines predictive accuracy in a gambling context, but does not consider the profitability of alternative prediction processes.
