The econometrics of female labor supply and children

This is a survey of applied econometric research on the effects of children on female labor supply. Reasons for interest in the topic, and a basic model and terminology, are reviewed. Concerns are raised about the possible endogeneity of child status variables, and about the instrumental variables approach for dealing with this problem. Alternative ways of conceptualizing and estimating child status effects are considered, together with selected empirical evidence. Relevant developments from the household demand literature are summarized. Basic issues of model choice are also discussed.     

Ninth-Grade Students' Attitudes Toward Nontraditional Occupations

Partner Choice and the Differential Retreat From Marriage

The contemporary retreat from marriage in the United States has had a differential impact across socioeconomic and racial groups. Here, 1990 marriage rates and propensities for Virginia, North Carolina, and Wisconsin are analyzed regarding (a) the likelihood that persons in different groups ever marry and (b) patterns of partner choice with respect to race and educational level. Marriage remains strong in most race‐education groups but is substantially lower among Blacks and among those with less than 12 years of education. Patterns of partner choice have shifted to show greater symmetry between the educational levels of brides and grooms. Changes have been modest with regard to the level and pattern of interracial (Black‐White) marriage. Marriage is increasingly a union of equals, but a union chosen more by Whites than by Blacks and more by the well educated than by the poorly educated.     

The merton thesis: Oetinger and German Pietism,a significant negative case

The Merton thesis identifies two movements — English Puritanism and German Pietism — as causally significant in the development of the scientific revolution of the 17th and 18th centuries. It attributes this connection to a strong compatibility between the values of ascetic Protestantism and those associated with modern science. This article questions Merton's conclusion regarding one of these movements, German Pietism, by arguing that the Pietist ethos stood in sharp conflict with what Merton has called the normative structure of science. One manifestation of this conflict involves Friedrich Oetinger's articulation of a contending religious-mystical conception of science, which assigned a central place to feeling, intuition, the role of the divine, and a qualitative approach to nature. This conception of science, it is argued, provides the clearest indication of the conceptual and valuative distance that tended to separate Pietists from the new science of the 17th and 18th centuries.An earlier version of this article was presented at the 1990 meeting of the Society for the Scientific Study of Religion, in Virginia Beach.     

Seasonal patterns of fertility measures: theory and data

The distribution of births by month exhibits a seasonal pattern in most populations. The monthly marital fertility rate for an area of Bangladesh provides a good example of the seasonal periodicity. Seasonal patterns of measures of reproduction in a population of married women are considered. Equations are developed that predict the seasonal patterns of these alternative measures under the assumption that the fertility rate (R) follows a trigonometric curve. This is followed by an empirical analysis of the measures in a Bangladesh population that has a pronounced seasonal fertility. The investigation is intended both to validate the theoretical framework developed in the 1st part of the paper as well as to determine whether seasonal variation in actual populations is sufficiently large to affect the alternative measures significantly. 4 measures are considered: pregnancy prevalence (PP)--the proportion of married women who are pregnant at the survey date; mean open birth interval (MOI)--the time from the last live birth to the date of the survey for parous women and from the time of marriage to the date of the survey for nulliparous women; mean closed interval-birth (MCIB)--the mean interval between the last 2 live births for married women who have a birth in the period immediately preceding the survey date; and mean closed interval-woman (MCIW)--the mean interval between the last 2 live births for women who have had at least 2 children by the time of the survey. It is assumed that the seasonal pattern of the fertility rate of a population follows a cosine curve and that there is no trend in annual fertility from year to year. The lag and relative variability of the other measures are considered in comparison with the fertility rate curve. The predictions from this theoretical effort, when compared with observed patterns and trigonometric regression results for each measure in data from Bangladesh, are shown to be quite accurate. The figure and regression results show that R, PP, and MOI have definite seasonal periodicity, but MCIB and MCIW do not display any seasonal patterns. If there is a secular trend in fertility in addition to seasonality, these relationships between the seasonal patterns of the measures may no longer hold. There is a disadvantage to using closed interval measures, for they are unable to detect effects of limiting of childbearing in a population since they are based only on information from women who have births.     

Contraceptive behavior among unmarried young women: A theoretical framework for research

Adoption of the most effective methods of contraception requires individual decision-making and negotiation with contraceptive providers. In order to take account of both behavioral elements, a two-dimensional framework for understanding contraceptive adoption and continuation by unmarried young is proposed, incorporating a "social-psychological model" of individual decision-making and an "interpersonal model" of factors affecting provider-client interaction. The social-psychological model is based on an earlier value-expectancy theory of behavior motivation as applied to health-related behaviors. The interpersonal model is derived from conflict-bargaining perspectives on professional-client interaction; it is suggested that expectations for this interaction are based on a limited number of internalized "models": the "professional"; the "bureaucratic"; the "commercial"; and the "parental." Insofar as client and professional "models" disagree, communication may break down and client understanding and/or acceptance of provider advice cannot be assured. The components of the social-psychological and interpersonal models are described in detail, and a combined framework is proposed.

LIMITED ASSET MARKET PARTICIPATION AND THE EURO AREA CRISIS: AN EMPIRICAL DSGE MODEL

We estimate a medium‐scale dynamic stochastic general equilibrium model for the Euro area with limited asset market participation (LAMP). Our results suggest that in the recent European Monetary Union years LAMP is particularly sizable (39% during 1993–2012) and important to understand business cycle features. The Bayes factor and the forecasting performance show that the LAMP model is preferred to its representative household counterpart. In the representative agent model the risk premium shock is the main driver of output volatility in order to match consumption correlation with output. In the LAMP model this role is played by the investment‐specific shock, because non‐Ricardian households introduce a Keynesian multiplier effect and raise the correlation between consumption and investments. We also detect the contractionary role of monetary policy shocks during the post‐2007 years. In this period consumption of non‐Ricardian households fell dramatically, but this outcome might have been avoided by a more aggressive policy stance. (JEL C11, C13, C32, E21, E32, E37)
