In this paper, we present new estimates of the effect of changes in workers’ compensation benefits on benefit duration and application frequency. Using administrative data for the state of California, we estimate the duration and frequency effects resulting from two increases in temporary disability benefits occurring during the mid 1990s. We employ a quasi-experimental research design that exp...
BACKGROUND Antioxidant supplementations have the potential to alleviate the atherosclerotic damage caused by excessive production of reactive oxygen species (ROS). The present study evaluated the effects of prolonged antioxidant treatment on arterial elasticity, inflammatory and metabolic measures in patients with multiple cardiovascular risk factors. METHODS Study participants were randomly ...
We prove that, given a stress-free, axially symmetric elastic body, there exists, for sufficiently small values of the gravitational constant and of the angular frequency, a unique stationary axisymmetric solution to the Einstein equations coupled to the equations of relativistic elasticity with the body performing rigid rotations around the symmetry axis at the given angular frequency.

We study optimal dynamic tax evasion in the framework proposed by Lin and Yang (2001) and Dzhumashev and Gahramanov (2011) with somemodifications: a more flexible utility function, a more realistic audit process, and a penalty function which can be defined both on evaded income and evaded taxes. In the former case the elasticity between tax rate and tax evasion is positive, unless the subsisten...
Introduction & Objectives: Coronary artery disease is a common cause of death over the world. The aim of this study was to compare the risk factors frequency in patients with ST-elevation MI & patients with non ST-elevation MI referring to Hamadan Ekabatan hospital in 2012. Materials & Methods: In this cross sectional- descriptive study with referring to the files of patients, those having AMI ...
background: leukoaraiosis (la) or white matter thinning and rarefaction are common in stroke patients. this pilot double-center study was designed to evaluate la risk factors in stroke patients. methods: this cross sectional study was conducted on 100 consecutive stroke patients in walter mackenzie hospital, canada and 100 consecutive stroke patients in valie-asr hospital , iran in 2004. diag...
We show that regional differences in returns to information technology (IT) investments by US firms are attributable in part to IT spillovers generated by the flow of IT workers among firms. We use a newly developed source of employee micro-data with employer identifiers and location information to model IT workers’ mobility patterns. Access to an external IT pool that is one standard deviation...
We show that substantial regional differences in returns to information technology (IT) investments by US firms are attributable in part to knowledge spillovers generated by the movements of IT workers among firms. We use a newly developed source of employee micro-data with employer identifiers and location information to model IT workers’ mobility patterns. Access to an external IT pool one st...
Economists typically assume that risk compensation is uniformly self-protective – that people become more careful as the health risks of their actions increase. However, risk-seeking, or fatalistic, responses can also be rational: increased risks can lead people to take fewer precautions. I extend the typical model of risk compensation to show that fatalism is a rational response to sufficientl...
