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.     

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.     

Executive Stock Ownership After the Acquisition

How does a company, buying another company, replace the acquired company's executive stock options? This article details what companies are doing and examines the advantages and disadvantages of replacing these options. The authors propose that the success or failure of an acquisition can hinge on the resolution of these issues.     

The model based on the matrix of economic growth

This paper is concerned with some aspects of direct and indirect growth rates of sectors and with the model based on the matrix of economic growth. The purpose of this consideration is to determine through indirect growth rates the growth structure of economy and to construct the model which may be used for the planning goals. In other words, by means of the matrix of growth or the model which is based on it we can estimate the future development of the economy. This can be done under different assumptions no matter whether relations are transfered from the past into the future or whether various relations change in future periods on the basis of streamlined elements of the plan. Hence, it can be determined either from the assumption that past relations will be kept approximately in the same frames, or that they will change in the future. In each case all the changes can be described through direct and indirect growth rates.     

Fiscal Coordination and Political Competition

This contribution investigates fiscal coordination in the framework of two countries asymmetric in respect of their capital–labor endowment. When tax policies are decided by majority voting inside each country, and they are not coordinated at a supranational level, factors of production are inefficiently allocated, at equilibrium. Our main result shows that fiscal coordination, via a minimum capital tax, does not always lead to a Pareto–improvement for the median voter's welfare, with respect to the noncooperative outcome.     

Integrating benefits decision making

Integrated employee benefit decision making helps employees use their benefits more wisely and identify opportunities to balance their immediate benefits needs (such as health care) and future benefits needs (such as retirement). This article discusses how employers can overcome employees' behavioral barriers to making integrated employee benefit decisions by changing the ways benefits are communicated and employees are presented with action decisions. Undertaking these steps allows employers to not only improve their employees' overall financial perspectives, but also furthers plan sponsors' goals of actively promoting personal responsibility with respect to retirement funding and changing employee behavior with respect to controlling health care costs.
