State dependency in youth unemployment: A lost generation?

Utilizing a job search framework and survey data on both completed and uncompleted spells of unemployment we present in this paper maximum likelihood estimates of the determinants of re-employment probabilities of young workers in Britain. The model used allows us to examine the importance of state dependency in youth unemployment as well as ethnicity, educational qualifications, and unemployment income. Results suggest that there is strong evidence of negative duration dependence in the transition from unemployment to employment for young workers in Britain.     

FOOD COST STABILIZATION USING FOOD COUPONS*

Given the goal of food cost stability, this paper proposes a consumer subsidy plan via food coupons. Graphic models of such a plan and the more conventional alternatives—price, control and consumer subsidy without use of coupons—are presented to describe how the schemes would operate and the direct effects which they might have. Simulation is then used to estimate their likely effects. Finally, the relative merits of the alternative stabilizing schemes are discussed from a policy point of view.
Ayant en vue le but de la stabilisation des couts alimentaires, cet article propose au consommateurs tin plan de subvention par coupons. Des modèles graphiques ďun tel plan el les alternatives plus tradilionnelles (c'est à dire contrôle de prix et subvention sans coupons') sont présentés afin de décrire les opérations et les effets qu'ils pourraient avoir. La simulation est employée afin de déterminer leurs consequences probables. Enfin les mérites relatifs des alternatives qui stabilize les prix sont discutés du point de vue politique.     

ON DECISION-MAKING FOR MAXIMUM PROFIT PER UNIT OF TIME FROM BATCH PRODUCTION

Finding ration sequences which result in maximum profit per day from fattening batches of livestock over successive weight intervals has posed difficulties in earlier studies. Fractional and dynamic programming are considered as solution methods and illustrated for a problem previously solved by total enumeration. Other problems are discussed which would be best solved by a combination of the two methods. A novel proposal is made for using the two methods to maximise the present value of returns from sequencing weight gains over infinite production cycles.     

Roles, role performance, and radical innovation competences

Despite the importance of radical innovations (RI), few firms have the capability to develop such innovations internally; success is increasingly linked with relationships and networks. However, the way(s) in which relationships and networks support RI is less clear. Successfully launching RIs requires the development of four distinctive competences; discovery, incubation, acceleration and commercialization. This paper examines how networks support the development of RIs, focusing on when and how network partners become involved and how their role performances support the development of the four competences. The study context is the automotive industry, which is heavily dependent upon RI and complex interrelationships. Data were collected through in-depth interviews with network participants involved in developing several RIs. Five task-oriented and three network-oriented roles are uncovered and the performance of these roles supports the development of different competences, with some roles being exclusively connected with particular competences and others supporting several competences. Focusing on role performance offers a useful means for distinguishing between acontextual actors, and the activities and resources they bring. In doing so, the paper enhances understanding of the links between network participants, role performances and the development of RI competences, and identifies a number of important implications for theory and practice.     

The heterogenous relationship of food stamp participation with body mass: Quantile regression model

This study explores the heterogenous relationship between Food Stamp Program (FSP) participation and body mass index (BMI) for low income individuals whose per capita family income falls in the bottom two quintiles. We estimate changes in the dispersion of the entire distribution of BMI following FSP participation using a quantile regression model in both cross-sectional and longitudinal analyses. For women, we find that the mean OLS estimate of FSP participation underestimates the extent of the positive association with BMI at the top quantiles in both cross-sectional and longitudinal individual fixed effects models. Controlling for individual fixed effects in the quantile regression model reduces the estimated magnitude of the association by a factor of three to four, although the estimates remain statistically significant for women. For men, a marginally statistically significant positive association of FSP participation with BMI is found at the top quantiles compared to no statistically significant mean estimate although the association is no longer statistically significant when time-constant individual heterogeneity is adjusted for in the individual fixed effect models.     

Maternal Depression and the Production of Infant Health

Depression is most prevalent among women of childbearing age and among low-income women, and the medical literature shows it to have adverse effects on infant health. Yet maternal depression has been overlooked in economic studies of infant health production. This research incorporates maternal depressive symptoms into a standard infant health production model and estimates both structural and reduced-form birth weight equations using samples of non-Hispanic white and black women from the National Maternal and Infant Health Survey. A byproduct of this research is an empirical investigation into factors associated with maternal depressive symptoms. All results show that depressive symptoms have a negative effect on birth weight and that they may operate through several channels such as smoking and prenatal care.     

FINANCIAL CONSISTENCY IN LONGITUDINAL MICROSIMULATION: HOMEMAKER PENSIONS RE-EXAMINED

Transfer programs, including public pension plans, do not generate wealth. In this paper methods of distributional analysis that lack budget constraints and are prone to illusions of wealth creation are criticized. A microsimulation analysis reported in "Homemaker Pension and Lifetime Redistribution" (Wolfson, 1988) is repeated using a conceptual framework that imposes a balance between the positive and negative impacts of transfer programs. This alternate analytical perspective reverses the distributional conclusions of the earlier study conducted using the same model.     

Punishment in a Regulatory Setting: Experimental Evidence from the VCM

To analyze the effectiveness of punishment in inducing regulatory compliance, we modify a standard public goods experiment to include a financial penalty for free riding. The design allows us to vary both punishment probability and severity. We introduce the punishment mechanism in both a one-time and a repeated treatment and find that compliance (contributing to the public good) is increasing in expected punishment cost in both treatments. We also find that punishment severity has a larger effect on behavior than punishment probability. In the repeated treatment, we find that past punishment has a negative rather than positive effect on compliance.     

The viability of alternative call centre production models

In this article we outline three alternative production models and discuss their applicability to call centre management. These include the classic mass production model, the professional service model and the mass customisation model. We then develop a theoretical framework that identifies potential causal links between management practices, workers? affective and cognitive reactions, and performance outcomes. We use this framework to review literature on service workplaces in organisational behaviour and HR studies and to assess the empirical evidence regarding these causal explanations. Finally, we present two recent quantitative studies of call centre performance – one that examines affective explanations and one that explores cognitive explanations for the HRperformance link. We conclude with directions for future research.
