We analyze a multiple-stage supply chain model of a seasonal product with pricing decisions. We develop closed-form expressions for the optimal expected profits of different stages. The results enable us to quantify the loss of supply chain profits if uncoordinated pricing decisions are made by supply chain agents.

When reform has no direct aggregate effects, but only changes agents’ incentives to act, uncertainty can weaken its effect. Because agents learn about policy change by observing their signals, increasing signal noise makes it harder for agents to know that reform has occurred. When policy changes are difficult to observe, they change agents’ actions less and have less aggregate effect. This is ...

Nasopharyngeal samples of vaccinated and non-vaccinated patients presenting with Influenza-like-illness (ILI) were collected from over 20 outpatient clinics located in different geographic parts of Israel and were tested for the presence of influenza viruses (influenza A and influenza...

Ineffectiveness of Dexamelhasone for Treatment of Experimental Cerebral Infarction • Ischemic cerebral edema occurring with cerebral infarction may cause increases of intracranial pressure and neurological deficits or death. Certain other types of cerebral edema are influenced by adrenal glucocorticoids; there is conflicting evidence about effects on ischemic edema, largely due to differences i...

Over a period of sixteen months, twenty seven patients of iron deficiency anemia, who had failed to respond to treatment with various iron preparations containing iron polymaltose complex were encountered. Despite several reports of ineffectiveness or poor effectiveness of iron polymaltose, large number of iron preparations containing iron polymaltose are vigorously promoted by many pharmaceuti...

A patient required mitral valve replacement following ineffective antibiotic treatment of enterococcal endocarditis caused by Streptococcus faecium. Endocarditis had relapsed despite therapy with ampicillin and tobramycin for six weeks. A second relapse had occurred following treatment with penicillin and gentamicin. Initial failure of antibiotic therapy may be related to the known lack of in v...

Two-thirds of education production function studies relating learning to school and parental inputs also include parental income. This confounds demand and production functions, since in demand functions income determines the school inputs used in the production function. In a comprehensive review of the literature, we show that with this misspecification significantly positive school input coe...
