Abstract

The rate of time preference is a fact that exists in the outside world and reality, and some economists believe that zero-time preference rate is zero is compatible with intergenerational justice. Some Muslim economists are also of the opinion that Islamic values seek to reduce this external reality, and as a result, they consider the time preference rate to be zero or close to zero as an indicator of the society’s approach to intergenerational justice. Assuming that the rate of time preference is an indicator for the society’s approach to intergenerational justice, therefore it is always possible to measure the distance of the society from the value of intergenerational justice by measuring this index.

There are different methods to measure this rate according to the factors that affect it, one of these methods is based on behavioral or traditional Stochastic Discount Factor (SDF) estimation, and this research also intends to use the data of the Iranian capital market. And with the help of behavioral and traditional SDF models to estimate the rate of time preference.

The research results indicate that the time preference factor in the traditional SDF and behavioral SDF models is 0.98 and 0.84, respectively, and because the time preference rate obtained from the time preference factor in the traditional model is equal to 0.12 and in the behavioral model is equal to is 0.19, so it can be concluded that the pricing model containing emotion shows the distance of the society from the intergenerational justice-oriented society.
