Female labor market activity is dependent on the presence and the age of a child, but how do the determinants develop in magnitude and significance with the child’s age? Using German SOEP data from 1991 to 2006 for mothers with young children, the change in maternal labor supply when the child is one, two, and three years old is explicitly addressed. According to the detailed descriptive analys...

This paper examines the determinants of export performance of firms in the Greek manufacturing industry, using cross-sectional data from 1652 firms in 1999 and a Tobit regression model. The study finds that firms that have larger size, lower unit labor cost and low capital to labor ratio have a higher propensity to export, confirming the fact that in Greece, which has the second lowest capital ...

This study focuses on a comparison and evaluation of models and estimators appropriate for time-use data. The tobit type I as well as different generalizations are used. According to our findings, a simple tobit I method can produce results that are similar and in some cases even better to the much more sophisticated methods. This is especially true if the participation or index equation is inc...

BACKGROUND Evidence is lacking on whether health guidance for metabolic syndrome reduces health care expenditures. The author used propensity-score matching to evaluate the effects of health guidance on health care expenditure. METHODS Men who did and did not receive health guidance from a health insurance society (approximately 60 000 covered lives) were matched (n = 397 respectively) using ...

Tobit models are extended to allow threshold values which depend on individuals’ characteristics. In such models, the parameters are subject to as many inequality constraints as the number of observations, and the maximum likelihood estimation which requires the numerical maximisation of the likelihood is often difficult to be implemented. Using a Bayesian approach, a Gibbs sampler algorithm is...

The health care sector depends to a large extent on human labour. Poor workers’ motivation can greatly affect health outcomes and patient safety. This study examines the influences of motivation on the performance of health care workers using University of llorin Teaching Hospital as case study. 150 questionnaires were administered out which 105 were returned. 59.05% of the workers experienced ...

We read with interest the article by Caprioli et al. in the June 2011 issue. In this article, the authors propose a novel method of measuring and predicting the rate of visual field (VF) decay in glaucoma patients. This is an important and clinically relevant topic. Of particular interest was the authors’ application of an exponential fit for threshold sensitivity (in decibels) against time, wh...
