Optimal Inventory Control with Retail Pre‐Packs

A pre‐pack is a collection of items used in retail distribution. By grouping multiple units of one or more stock keeping units (SKU), distribution and handling costs can be reduced; however, ordering flexibility at the retail outlet is limited. This paper studies an inventory system at a retail level where both pre‐packs and individual items (at additional handling cost) can be ordered. For a single‐SKU, single‐period problem, we show that the optimal policy is to order into a “band” with as few individual units as possible. For the multi‐period problem with modular demand, the band policy is still optimal, and the steady‐state distribution of the target inventory position possesses a semi‐uniform structure, which greatly facilitates the computation of optimal policies and approximations under general demand. For the multi‐SKU case, the optimal policy has a generalized band structure. Our numerical results show that pre‐pack use is beneficial when facing stable and complementary demands, and substantial handling savings at the distribution center. The cost premium of using simple policies, such as strict base‐stock and batch‐ordering (pre‐packs only), can be substantial for medium parameter ranges.     

The simultaneous examination of economic and social factors in destination selection: Employing objective and subjective measures

This research examines the role of social and economic factors in the past selection of destinations made by migrants living in Rhode Island. Results indicate that social ties play a more important role in the selection of destinations with low levels of opportunity than they do in the movement to high opportunity areas. An important aspect of the study was the simultaneous investigation of both objective and subjective measures of social and economic factors in the selection of low and high growth destinations. The analysis suggests that the simultaneous consideration of objective and subjective factors provides a more refined accounting of the potential influence of social and economic factors in the selection of destinations. The findings hold when age is introduced as a control.     

Measuring trends in child well-being: an evidence-based approach

This paper first reviews the goals of the founding documents of the social indicators and quality-of-life movements of the 1960s and 1970s. It next describes the current state of knowledge with respect to the founding goals of this field. The focus then turns to the topic of measuring changes in child and youth well-being in the United States over the past few decades. In particular, the evidence-based approach used in the construction of the recently developed composite Child and Youth Well-Being Index (CWI) is described. Some findings from the CWI regarding changes in child and youth well-being in the period 1975–2004 are reported. Trends in the CWI then are compared with data on trends in subjective well-being of high school seniors – similarities of trends in these two series provide validating support for the interpretation of the CWI as an index of changes in the quality-of-life of children and youth. Using data on some additional indicator series, most of which were initiated in the 1990s, an Expanded CWI is then described. The qualitative pattern of change in the expanded CWI is shown to be similar to that of the basic CWI, except that the expanded CWI shows a more pronounced decline in the early-1990s and a slower rate of improvement into the early-2000s. The paper concludes with some possible directions for future work.

Length of residence,social ties,and economic opportunities

This study examines length of residence for movers—that subsection of the population which accounts for the high mobility rates in the United States. The propensity for repeated migration is studied in relation to economic opportunities and previous familial and personal contacts. The results indicate no influence of economic opportunities on duration of residence. This finding is consistent with recent research that indicates economic conditions are not a general stimulus for out-migration, although they are for in-migration. On the other hand, length of residence is found to be longer where previous familial and personal contacts existed. Overall, the results provide additional evidence of the importance of social, as opposed to strictly economic, variables in the migration process.     

Urbanization and the fertility transition in Ghana

This paper examines the way in which migration and urban residence operate to alter fertility outcomes. While urban-rural fertility differentials have long been established for most developing societies, the nature of these differences among migrants and between migrants and those of succeeding generations is not well understood. The evidence presented here suggests that rural-urban migration and urbanization may contribute positively to processes of fertility transition. Using data from the 1998 Kumasi Peri-Urban Survey, which included a 5-year retrospective monthly calendar of childbearing, we suggest that migrants adapt quickly to an urban environment. Our results also reveal generational differences in recent and cumulative fertility. While migrants exhibit higher cumulative fertility than urban residents of the second and third generation, their fertility is significantly lower than rural averages in Ghana. Children of migrants exhibit childbearing patterns quite similar to those in higher-order generations. Most noteworthy is the nature of the disparities in childbearing patterns between migrants and the succeeding generations. Migrant women have higher lifetime fertility than urban natives. Migrant women also exhibit higher fertility over the last 5 years than second generation or high-order urban natives. But these first generation women exhibit lower fertility (vs. urban natives) for the year immediately prior to the survey. These patterns lend support to an interpretation that combines rather than opposes theories of selectivity, disruption, adaptation and socialization. We conclude by discussing mechanisms that might explain these interrelated processes of fertility adjustment and suggest that policies discouraging rural-urban migration need to be revisited.     

Welfare states and social mobility: How educational and social policy may affect cross-national differences in the association between occupational origins and destinations

Cross-national differences in the association between origins and destinations correspond to differences in both welfare regime type and access to post-secondary education. Socialist and social democratic welfare regimes foster a weaker origin–destination association than liberal, corporatist, or mixed regimes do. Nations with better-educated labor forces tend to also be the nations where the association between origins and destinations is weakest. Furthermore, the social and educational policy interact so that the tendency for educational access to lower the origin–destination association is most pronounced in the liberal welfare setting where the association would otherwise be greatest. Greater access is not necessarily associated with greater equality of opportunity, and we find very weak evidence that equality of educational opportunity itself is a direct influence on equality of occupational opportunity (even though nations that have a strong origin–education association also have a strong origin–destination association).

Changes in psychosocial well-being during stages of gay identity development

The current study evaluated the stage theory of Homosexual Identity Formation (HIF) developed by Cass (1979), in terms of the relationship between stage of gay identity development and psychosocial well-being. Four hundred twenty-five males (12 to 64 years, M = 29.2) reporting sexual attraction to other men provided demographic information and completed psychosocial measures: the Happiness-Sadness Scale (McGreal & Joseph, 1993), the Satisfaction with Life Scale (Diener, Emmons, Larsen & Griffin, 1985), the UCLA Loneliness Scale (Russell, Peplau & Ferguson, 1978), the Index of Self-Esteem (Hudson, 1982), and the Gay Identity Questionnaire (Brady & Busse, 1994). Correlation analysis and ANCOVAs controlling for age and nationality demonstrated that the 6 sequential stages of HIF were associated with a U-shaped function for the psychosocial variables. Well-being was high during the initial Confusion and Comparison stages of HIF, was reduced during the middle Tolerance and Acceptance stages, and was again high in the later Pride and Synthesis stages. Each of the psychosocial variables was significantly different according to stage of development (p <.001). Qualitative analysis of subjects' comments also revealed support for the U-shaped pattern.
