Aggregate male and female labor force participation functions: An analysis of structural differences, 1947–1977

The hypothesis that the structure of the forces that affect male and female labor force participation rates are distinct has been corroborated in numerous studies using microdata. This paper examines the validity of this structural distinctiveness hypothesis in the context of aggregate, time series data on male and female labor force participation in the post-World War II United States. Standard economic and sociological theories are used to specify sex-specific participation functions that contain indexes of the sex-specific general opportunity for employment, the sex-specific rates of participation in the armed forces and in postsecondary schooling institutions, the average real wage rate, the average number of hours worked, and the fertility rate. It is found that the female rate is more responsive than the male rate to the general employment opportunities and average hours indexes, but less responsive to the wage rate. Also, the female rate responds positively to the armed forces participation and college enrollment rates, whereas the male rate is negatively related to these indexes. However, no evidence is found for another component of the structural distinctiveness hypothesis, namely, that the fertility rate bears a consistent negative relationship to the female participation rate. While this relationship may have held during the early postwar years, it seems to have been substantially attentuated since the early 1960s. Prospects for convergence of the male and female participation functions are evaluated. Although current social trends suggest that the female function eventually will resemble more closely the male funtion, it is concluded that substantial sex differences are likely to persist for at least another decade. Implications of this for the structure of the labor force participation functions used in macroeconometric forecasting models are discussed.     

Alternatives and options in computer content analysis

First developed in the early 1960s, computer content analysis methods stimulated renewed interest in the quantitative analysis of verbal materials. Continued research and development of such methods produced a range of current alternatives and options. Investigators can choose between advanced systems varying widely in amount of theoretical prestructuring required and complexity of units of analysis, or they can devise less complex systems built upon basic work processing programs.     

Deception in simple voting games

The calculations of sophisticated voters who successively eliminate undesirable strategies are analyzed in three-person voting games in which one voter with complete information can, as a deceiver, induce the other two voters with incomplete information to vote in such a way as to ensure a better outcome than the deceiver could ensure in a game of complete information. Deception which is “tacit,” wherein a deceiver votes consistently with his announced preference scale, is distinguished from deception which is “revealed,” wherein a deceiver's action deviates from his announced preference scale. Among the conclusions drawn from the study is that revealed deception is generally a more potent tool than tacit deception in securing a more-preferred outcome, and deception opportunities are greater the more disagreement there is among the nondeceivers.     

Youth service caseworkers: Social and legal factors affecting their recommendation to place youths in secure care facilities

This study examines the effects of social and legal variables on youth service caseworkers' recommendation to place youths in a secure care setting. While the findings of this study indicate that caseworkers' recommendation to place youths in such a facility is primarily influenced by their juvenile delinquency or legal background characteristics, the social variable “family composition” has a significant impact on the recommendation. This suggests that caseworkers view single-parent families as less capable than two-parent families of managing youths' serious delinquency problems and, therefore, are more likely to recommend youths from single-parent families for secure care placement consideration. The fact that legal variables are the strongest predictors of secure care decision outcomes indicates that objective criteria are being used to determine which youths to consider for secure care placement. Also, it is found that the more offenses that are committed the more likely that one will be a violent offense. This finding implies that the issue of serious juvenile delinquency should be examined and dealt with from a broad juvenile justice perspective directed at prevention as opposed to a limited focus on only the secure care process.     

Road signs in ethical quicksand

This commentary highlights some of the major moral and ethical dilemmas illustrated by authors in this special issue. From an ethical viewpoint, the complexity of evaluation activities is likened to “quicksand” terrain in which directional or warning signs should be erected to aid personal choices when such issues are encountered. However, even previous training and personal introspection are inadequate to completely avoid, circumvent, or handle a specific situation because of its complexity and the competing values inherent in ethical choices.     

Recursive models for categorical data

Standard methods for recursive models with continuous endogenous variables are extended to models with categorical endogenous variables. The concept of a reduced-form equation is generalized in a natural way to cover nonlinear regression functions and, in particular, models with categorical endogenous variables. Maximum-likelihood estimation and asymptotic chi-square tests are described. Two numerical examples are presented: a linear recursive two-equation model for all-categorical data, and a combined linear and logit three-equation recursive model with both categorical and continuous endogenous variables. Limitations of the present work and directions for further extension are noted.
