gilan province is among the most important regions of iran for rice production. the general aim of this research is to determine the best variety of rice for planting, so that the minimum level for farmer's expected living gross margin can be provided. on the other hand, determining the best variety with regard to the risk in price is another aim of this research. to this end two risk models ba...

The impact of aging on healthcare expenditure (HCE) has been at the center of a prolonged debate. This paper purports to shed light on several issues of this debate by presenting new evidence on the "red herring" hypothesis advanced by Zweifel, Felder and Meier (1999). This hypothesis amounts to distinguishing a mortality from a morbidity component in healthcare expenditure (HCE) and claiming t...

The formation of an optimal portfolio can be done with the Safety First Criterion method which is based on down side risk, namely risk causing a loss. purpose this study to determine using method. first criteria for selection are concerned only failing achieve minimum target return or secure prespecified safety margins. There three First, Roy, Kataoka and Telser criteria. results formed differe...

Using Telser and Kataoka models of probabilistic-risky mathematical programming, the present research is to determine the optimized pattern of cultivating the agricultural products of Shoshtar region under risky conditions. In order to consider the risk in the mentioned models, time period of agricultural years 1996-1997 till 2004-2005 was taken into account. Results from Telser and Kataoka mod...

In this study, we show how a dynamic insurance program can be implemented within a mean-variance framework. The approach combines elements of the single period safety first idea suggested by Telser and developed by Leibowitz with multiperiod insurance strategies like CPPI and TIPP. The insurance program allows the user to set a probability of hitting a specified floor or target and also allows ...
