THE EFFECTS OF LEAD TIME ON PLANT TIMING AND SIZE

An important issue in planning capacity expansion under uncertain demand is the effect of lead time on the timing of plant construction. Our model helps decide whether (1) plant construction is initiated after a certain deficit is accumulated, or (2) plant construction is initiated ahead of demand when a certain capacity surplus is reached. In addition to our analytical results, we present computational results to show that it is economically attractive to delay plant construction beyond the time when existing excess capacity becomes fully absorbed, with relatively short construction lead time.     

Unequal networks: comparing the pre‐migration overseas networks of Indonesian and Filipino migrant domestic workers

Previous studies of Asian migrant domestic workers' pre‐migration overseas networks have tended to be ethnographic, small‐n case studies such that it is unclear if network differences between migrants are due to individual‐ or country‐level differences or both. This article draws from an original survey of 1,206 Filipino and Indonesian domestic workers in Singapore and Hong Kong to reveal statistically significant differences in the pre‐migration overseas networks of these two nationality groups even after controlling for migrants' educational attainment, marital status, employment status, age, year of first migration, and survey location. Multiple regression analysis highlights how Filipino respondents are more likely than Indonesian respondents to have known existing migrants prior to their first migration from their homeland. Filipino respondents' overseas networks are also significantly larger, more geographically dispersed, and comprise more white‐collar contacts. These findings open up new terrain for migration scholars to study the impact of these nationality‐based network differences on the two groups' divergent migration experiences and aspirations.     

U.S. CREDIT UNIONS: SURVIVAL,CONSOLIDATION, AND GROWTH

This study uses hazard function estimations and time‐series and cross‐sectional growth regressions to examine the impact of exit through merger and acquisition (M&A) or failure, and internally generated growth, on the firm‐size distribution within the U.S. credit union sector. Consolidation through M&A was the principal cause of a reduction in the number of credit unions, but impact on concentration was small. Divergence between the average internally generated growth of smaller and larger credit unions was the principal driver of the rise in concentration. (JEL G21)

Mortality following conjugal bereavement,Belgium 1991-96: The unexpected effect of education

This paper examines excess mortality following spousal bereavement by time since bereavement, sex, age, and education. The main hypothesis challenged is that higher education buffers the harmful effects of spousal loss. Using a log-rate model, death-rate ratios (widowed/married) are estimated for 49,849 and 126,746 Belgian widowers and widows and an equal number of non-bereaved controls matched to the bereaved on their socio-demographic characteristics. The hypothesis that the more educated suffer less excess mortality is not supported. Although higher educational levels are associated with lower mortality in general, they do not alleviate the effects of bereavement. On the contrary, in the period immediately following spousal loss, the more highly educated seem to have more, rather than less, excess mortality. Three possible arguments are suggested to account for this: education-related differences in the partner-relationship, structural differences in the availability of appropriate social support, and cultural differences in potential support networks.     

ON IMPERFECT EVALUATION AND EARNING DIFFERENTIALS

This paper investigates the relationship between the technology for evaluating performance and optimal contract choice. Specifically, the paper examines the different compensation packages that arise when occupations differ in evaluation technology, workers are risk averse, work effort is endogenous, and there exists asymmetric information. In occupations in which it is less difficult to measure output, it is shown that compensation is more closely tied to output; the implications for work effort, the sorting of workers by ability, and average compensation are developed. Analysis of a new data set confirms our predictions concerning earning differentials and wage growth.
The powerful 1.6 million-member National Education Association and other teacher organizations have traditionally fought the notion of rewarding better teachers with more money, arguing that there is no objective way to measure a teacher's competence and that it would lead to favoritism, and bad morale [ Time , June 20, 1983].     

A Revisionist History of Intermediate Treatment

Correspondence to John Pratt, Department of Social Policy and Social Work, Massey University, Palmerston North, New Zeland. Summary This paper examines and challenges the view that intermediatetreatment for young offenders in England and Wales has alwaysbeen intended as an alternative to custody provision. It arguesthat its origin and subsequent development have to be understoodwithin what was the prevailing welfare discourse at the timeof the 1969 Children and Young Persons Act. It traces some ofthe processes involved in the change that has since taken place,characterized by a move from ‘welfare’ to ‘justice’talk, and suggests that it was only then that the conceptualspace for intermediate treatment to operate as an alternativeto custody was established. Finally, it examines some of thecritical issues raised by these changes in policy and discourse.     

AGGREGATE DEMAND CONTRACTIONS WITH NOMINAL DEBT COMMITMENTS: IS WAGE FLEXIBILITY STABILIZING?

When nominal debt payments commitments exist, output losses following an aggregate demand contraction will be larger and more persistent. Paradoxically, output can be less stable if wages are more flexible. This occurs because falling wages and prices cause debtors' cash flow to deteriorate relative to their debt commitments. To reduce the chance of incurring bankruptcy costs, debtors cut expenditure. Creditor's wealth increases from an unexpected deflation but their gain does not offset debtors' loss because of the increased threat of bankruptcy and associated costs. Net wealth and aggregate demand fall, magnifying the effect of the initial contraction.     

Sex Differences in the Characteristics of Members Lost to a Longitudinal Panel: A Speculative Research Note

A nine-year follow-up of former adolescents reveals sex differencesin the relative deviance and drug involvement of individualslost to the panel in young adulthood. As expected, men who werereinterviewed were less deviant than the noninterviewed, whilethe opposite was observed among women. Specification by raceindicates that the female pattern applies especially to nonwhites,but all women who are reinterviewed, irrespective of race, areno less deviant than the nonreinterviewed. The paradoxical findingfor females may result from changing marital status in thatparticular period of the life cycle and an inverse relationshipbetween delinquency and marriage.
