The Cohort Size‐Wage Relationship in Europe

This paper estimates the impact of cohort size on wages using data on young males in European regions covering 2004–10. The effect of cohort size on wages is identified through an instrumental variables strategy which, in contrast to previous analyses of European data, addresses self‐selection into geographical areas as well as into educational groups. The results suggest that cohort size has a significant negative effect on male wages for individuals with secondary education — the largest group — but not for individuals with less than secondary education or tertiary education. This effect is underestimated if self‐selection into geographical areas is not addressed.     

The Cost of High Unemployment

In response to R. A. B. Leaper's challenge in the last issue of this journal we present a report which we have just prepared for the BBC North-East. We believe that a better understanding of the costs of high unemployment to the country is needed to inform decisions on how much we can afford to pay to tackle the problem. In the final section of the paper we show how this evidence can be of value in costing policy options.
The last detailed costings of unemployment were published in 1982 for the financial year 1981/82. In February 1982 it appears that a political decision was taken not to publish the latest Treasury estimate updating their 1981 calculations. Since then numerous parliamentary questions on the subject have received very limited answers disputing the validity of the whole exercise.     

Psychological and cultural factors in the process of occupational achievement

An eight-equation model embodies the hypothesis that cultural differences among ethnic-religious groups give rise to differences in psychological dispositions, which, though not directly observable, influence occupational achievement, directly or via educational attainment, while being subject to feedback from one or the other of these endogenous variables. Dispositions are reflected in three fallible indicators, constructed from items in a survey interview of native white men in the Detroit area; the survey also secured socioeconomic measures and an estimate of intelligence. The model is block recursive and over-identified. Parameter estimates are secured by a sequence of ordinary least squares and two-stage least squares procedures, after solving out the structural equations to eliminate the unobservable variables. Numerical results do not strongly support the “Protestant Ethic” theory of achievement, but do suggest that the influence of education on occupation is mediated by motivational as well as cognitive and institutional factors.     

A note on deriving rank-dependent utility using additive joint receipts

Luce and Fishburn (1991) derived a general rank-dependent utility model using an operation ⊕ of joint receipt. Their argument rested on an empirically supported property (now) calledsegregation and on the assumption that utility is additive over ⊕. This note generalizes that conclusion to the case where utility need not be additive over ⊕, but rather is of a more general form, which they derived but did not use in their article. Tversky and Kahneman (1992), conjecturing that the joint receipt of two sums of money is simply their sum, criticized that original model because ⊕=+ together with additive utility implies the unacceptable conclusion that the utility of money is proportional to money. In the present generalized theory, if ⊕=+, utility is a negative exponential function of money rather than proportional. Similar results hold for losses. The case of mixed gains and losses is less well understood.     

Institutional Diversity and Performance in African Cotton Sectors

This article analyses the performance of cotton sectors across East, Southern, and West Africa, paying particular attention to the wide diversity of institutional arrangements that they now exhibit. It finds strong support for earlier contentions regarding trade‐offs between competition and coordination, and between the roles of public and private sectors. New insights provide concrete and context‐specific guidance to policy‐makers and stakeholders regarding the key challenges they will face and the risks they will need to manage as they work to improve productivity and ensure an equitable division of benefits within cotton sectors.     

Social work in mental health services: A survey of the field

Abstract

A survey of social workers employed in mental health services was conducted in Victoria in mid-1997. Approximately 300 social workers were identified as working in the sector. About half were employed in adult clinical services, 23% in psychiatric disability services, 12.4% in Child and Adolescent Mental Health Services, and the rest in a range of other services. More than 90% worked in a community based service or team. The number of entry-level (SW I) positions in clinical services was found to have declined over the last ten years from 61 to 14, resulting in a lack of opportunities for social workers to gain experience in base grade positions, and difficulty in recruiting to SW II positions. Major issues of concern reported by social workers included: the lack of accommodation and other community resources for consumers; diminished opportunities for professional development, supervision, and discipline-specific training; lack of professional recognition; increasing workloads; and organisational emphasis on throughput rather than quality.     

A Tale of Two Counties: Natives’ Opinions Toward Immigration in North Carolina1

This article compares native residents’ opinions and perceptions regarding immigration using a representative survey from a pair of matched North Carolina counties – one that experienced recent growth of its foreign-born population and one that did not. Drawing from several theoretical perspectives, including group threat, contact theory, and symbolic politics, we formulate and empirically evaluate several hypotheses. Results provide limited evidence that competition and threat influence formation of opinions about immigration, with modest support for claims that parents with school-aged children harbor more negative views of immigration than their childless counterparts. Except for residents in precarious economic situations, these negative opinions appear unrelated to the immigrant composition of the community. Claims that the media promotes negative views of immigration receive limited support, but this relationship is unrelated to the volume of local immigration. Finally, sustained contacts with foreign-born residents outside work environments are associated with positive views of immigration, but superficial contacts appear to be conducive to anti-immigration sentiments. Political orientation, educational attainment, and indicators of respondents’ tolerance for diversity explain most of the difference between the two counties in overall support for immigration.
