The effects of gender control on fertility and children's consumption

Effects of sex preference on investments in children‘s human capital, bequests and fertility are studied, with and without sex selection, in a model based on parental altruism. Both pure sex preference, a feature of the parental utility function, and indirect preference, which arises from gender-related differences in earnings opportunities, are examined. When there is no gender control the impact of pure sex preference is seen in smaller consumption for daughters than for sons. However, when gender control is exerted, sex preference raises the sex ratio and it is possible that sisters may, on average, consume no less than their more numerous brothers. In an example of the model with specific functional forms, parents who practise gender control have larger families than if sex selection techniques were unavailable. The effect is magnified if sons‘ earnings opportunities are better than daughters‘. JEL classification: D11, J13, J16 Received August 31, 1995 / Accepted May 2, 1996     

Economic advice as a vocation: symbioses of scientific and political authority

Academic economists perform an important function in advising politicians and state bureaucrats, lending them epistemological authority. This creates a challenge of institutional design and of professional vocation, of how these experts can combine their commitment to scientific analysis with their commitment towards their governmental patrons. This article examines the case of anti-trust economics, in which government economists are encouraged to remain as academically engaged as possible, so that their advice will be - or appear to be - unpolluted by political or bureaucratic pressures. Yet this ideal is constantly compromised by the fact that the economists are nevertheless government employees, working beneath lawyers. Max Weber's concept of a 'vocation' is adopted to explore this tension, and his two lectures, 'Science as a Vocation' and 'Politics as a Vocation' are read side by side, to consider this core dilemma of academic policy advisors.     

An influence method for outlier detection applied to time series traffic data

The work of Chernick et al. (1982) is extended to form a quantitative outlier detection statistic for use with time series data. The statistic is formed from the squared elements of the influence function matrix, where each element of the matrix gives the influence on the theoretical autocorrelation function at lag k (pk) of a pair of obser vations at time lag k. The approximate first four moments for the statistic are derived and, by fitting Johnson curves to these theoretical moments, critical points are also produced. The statistic is also used to form the basis of an adjustment procedure to treat outliers or estimate missing values in the time series. The nuclear power data of Chernick et al. and the traffic count data of the Department of Transport are used for practical illustration.     

Family matters: a discussion of the Bangladeshi and Pakistani extended family and community in supporting the children's education

This paper looks beyond an individualised type of parental involvement and discusses the role of the extended family in relation to school. We draw on the different social capital theories to explain its implications and also to discuss its efficacy. Our focus is on the Bangladeshi community and the Pakistani community in two towns in the North East of England. British South Asian parents are variously accused of having too high educational expectations of their children or not being interested at all and that Pakistani and Bangladeshi parents in particular have no or limited relationships with their children's schools. In this paper we demonstrate that parental involvement in these two communities resides not simply in the hands of the parents but within the wider family. We challenge the deficit model of British South Asian families as indifferent to the education of their children and we identify the potential resource of the extended family.     

Personal concepts of stability in the second half of life

The study contributes to the conceptualization of stability in the development of later life by answering four questions: Are there certain concepts of no-change in the population of aging adults? What are the issues that people combine with the idea of no-change? Are the issues of different importance for different groups? What kind of time perspective is expressed in their expectations of no-change?Stability expectations were investigated within a representative sample of about 2934 Germans aged 40–85 who live independently in the community. By means of a sentence completion instrument subjects provided spontaneous statements about self and life conceptions.Content analysis indicated clearly two different concepts of stability among the respondents in the second half of life: One concerns the continuation of gains, the other the maintenance of the status quo. One third of the expectations deals with further gains. Two thirds of the statements, however, refers to the maintenance of the status quo. Expected maintenance of the status quo showed a strong association with older age. In terms of Raynor's [Raynor, J. O. (1982). A theory of personal functioning and change. In J. O. Raynor & E. Entin (Eds.), Motivation, career striving and aging (pp. 249-302). Washington: Hemisphere Publishing Corporation] theory of the time-bound sense of self, the concept ‘continuation of gains’ reflects a future sense of self, while the concept ‘maintenance of the status quo’ refers to a more present sense of self.
