THE EFFECT OF PARENTAL EMPLOYMENT ON CHILD SCHOOLING

This paper presents a model that provides conditions under which a causal interpretation can be given to the association between childhood parental employment and subsequent educational attainments of children. The key parameter comes from theconditional demand function for children's future earning capacity. Its identification rests on having data on siblings and assumptions about the timing of parents' knowledge of their children's endowments. In addition to sibling differences, the useof a fixed‐effects instrumental‐variables estimator identifies the parameter under weaker conditions. Empirical analysis informed by the model reveals a negative and significant effect on the child's educational attainment of the months of the mother's full‐time employment when the child was aged 0–5. The effect of the mother's part‐time employment is smaller and less well determined, but again negative. These results suggest that the substitution effect of the mother's employment dominates the income effects. Stronger adverse effects are found for children of less‐educated mothers.

Consumer perspectives on the African sharptooth catfish in rural and urban areas of the Northern Province

This study evaluated consumer behavioural patterns in relation to meat products, with special reference to the African sharptooth catfish, in the Northern Province. Personal interviews were conducted in rural Ga‐Mamphaka and urban Giyani. The major meat type purchased was found to be chicken (71 per cent in the rural and 46 per cent in the urban community). The sharptooth catfish was found to be acceptable to the majority of respondents, both urban (69 per cent) and rural (57 per cent). Most respondents also indicated that they would like to purchase canned catfish. A potential market for catfish would seem to exist at a price competitive with that of chicken.     

Time costs,aspirations and the effect of economic growth on German fertility

Recent research has shown strong support for the model of reproductive behavior derived from the new home economics, and it is shown in this discussion that the evidence from the Federal Republic of Germany is consistent with the new home economics model. There is little support for Easterlin's relative economic hypothesis, but there is limited endorsement for model which adds the influence of experience based material aspirations to the new home economics model. Easterlin's relative income model is reviewed before directing attention to the new home economics model and an explanation of fertility movements in West Germany. The new home economics model focuses on the family division of labor between home activities and work outside the home. The marked decline in German fertility during the 1970s is mostly attributable to factors such as expanding women's earning capacities which increased the importance of 2 earner families, who have a different family division of labor and possibly preferences biased towards "quality" of children rather than numbers. Also, real wage growth lagged behind the growth in experience based aspirations, and this drop in relative income is more dramatic if it is presumed that material aspirations are based upon the family's income experienced by a young adult during his/her adolescence, rather than just the father's earnings. The mother's contribution to family income will contribute to her family's actual standard of living and the desired standard of living of her children. The labor force participation rates of married, middle-aged German women increased markedly during the 1st half of the 1950s, thus tending to enhance the increase in the standard of living desired by the young adults reaching marrying and childbearing ages in the mid-1960s. The analysis indicates that if there is not a substantial reduction in the proportion of young married women in the labor force, fertility will move countercyclically. In that there must be some floor to fertility, one should be cautious of using these parameter estimates considerably outside the 1950-1977 period. Nonetheless, the estimates indicate that economic growth will not bring a substantial rise in German fertility, and, outside the unlikely situation of sustained economic decline, fertility will remain low.     

Welfare benefits and the duration of single parenthood

The authors examine the contention that the provision of welfare benefits to single parents increases the number of single parents and the duration of single parenthood. Data are from the Women and Employment Survey, which collected marital, childbearing, and employment data from 5,320 women aged 16-59 in the United Kingdom in 1980. The results indicate that welfare benefits exercise no significant effect on the duration of single parenthood.     

On the economics of trials: adversarial process, evidence, and equilibrium bias

The adversarial provision of evidence is modeled as a game inwhich two parties engage in strategic sequential search. Anaxiomatic approach is used to characterize a court's decisionbased on the evidence provided. Although this process treatsthe evidence submissions in an unbiased way, the equilibriumoutcome may still exhibit bias. Bias arises from differencesin the cost of sampling or asymmetry in the sampling distribution.In a multistage model, a prodefendant bias arises in the firststage from a divergence between the parties' stakes. Finally,the adversarial process generates additional costs that screenout some otherwise meritorious cases.
