In talent-intensive jobs, workers’ quality is revealed by their performance. This enhances productivity and earnings, but also increases layoff risk. We show that, if firms compete for talent, they cannot insure workers against this risk, so that the more risk-averse will choose less quality-revealing jobs. lowers expected salaries. Our model predicts public unemployment insurance corrects inef...

Constraints on spin observables coming from discrete symmetries such as P, C, T and identical particles may be divided in two types: 1) classical ones, which insure the invariance of the cross sections under the symmetry operation; 2) non-classical ones, which can only be obtained at the level of amplitudes. Similarly, positivity constraints can be divided into classical and non-classical const...

Background Neonatology has evolved with respect to the needs of premature infants for special care. One of the major problems in premature infants is that their lungs are not developed adequately to fulfill newborns’ needs. There is a broad spectrum of strategies for management of respiratory problems in premature infants. In this study, we aimed to determine the best Strategies against Respira...

Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) is a progressive multisystem neuromuscular disorder. In addition to the skeletal muscle, the myocardium in the DMD/BMD patient is dystrophin deficient which results in a progressive cardiomyopathy. The myopathic myocardium poses significant risk of increased morbidity and mortality at the time of major surgical procedures. Careful ...

INTRODUCTION Recent regulatory pressures and certification requirements have heightened the need for payer organizations to abide by specific standards regarding medical management operations. Payer organizations that are making medical-necessity determinations regarding reimbursement for health care services, as well as risk-bearing provider groups to whom some of these functions have been del...

The empirical regularity known as Zipf’s law or the rank-size rule has motivated development of a theoretical literature to explain it. We examine the assumptions on consumer behavior, particularly about their inability to insure against the city-level productivity shocks, implicitly used in this literature. With either selfinsurance or insurance markets, and either an arbitrarily small cost of...
