There is a long tradition in economics about the question of whether intergenerational discounting is fair or not. Ramsey (1928) was the first economist that criticized the discounting and mentioned that the just rate of discounting is zero.  In this paper it was tried to calculate the just rate of discounting for Iran with respect to Islamic thoughts. According to Islam, intergenerational just...

T This paper analyzes different pricing strategies in a two-echelon supply chain including one supplier and two retailers. The supplier and the retailers face random yield and random demand, respectively. Moreover, coordination or non-coordination of retailers in receiving the discount is investigated. Game theory is used to model and analyze the problems. The supplier as a leader of Stackelbe...

In this entry we characterize pricing kernels or stochastic discount factors that are used to represent valuation operators in dynamic stochastic economies. A kernel is commonlyused mathematical term used to represent an operator. The term stochastic discount factor extends concepts from economics and finance to include adjustments for risk. As we will see, there is a tight connection between t...

This paper develops and studies a tough love model of intergenerational altruism. We model tough love by modifying the Barro-Becker standard altruism model in two ways. First, the child’s discount factor is endogenously determined, so that low consumption at young age leads to a higher discount factor later in her life. Second, the parent evaluates the child’s lifetime utility with a constant h...

In contrast to the existing literature on repeated games that assumes a Þxed discount factor, I study an environment in which it is more realistic to assume a ßuctuating discount factor. In a repeated oligopoly, as the interest rate changes, so too does the degree to which Þrms discount the future. I characterize the optimal tacit collusion equilibrium when the discount factor changes over time...

Suppose that consumers incur fixed shopping costs and choose stores according to advertised discounts. Then, the extent to which a store will discount advertised items should increase with the profit from other regularly-priced items. Bookstores customarily advertise discounts on bestsellers. Among conventional bookstores, we found that the bestseller discount systematically increased with the ...

The ordering model between single supplier and multi-retailers under the circumstance of non-cooperation supply chain is discussed in this paper, an improved linear price discount strategy is also provided. This strategy considers two situations of incremental discount and decremental discount at the same time. Moreover, Stackelberg game model of both parties’ order on supply and demand is give...

Gollier and Weitzman (2010) show that if future consumption discount rates are uncertain and persistent, the consumption discount rate should decline to its lowest possible value for events in the most distant future. In this paper, I argue that the lowest possible growth rate of consumption per capita in the distant future is zero (assuming that humans do not die out). Substituting in the Rams...

The perishable product’s dynamic pricing with quantity discount strategy is studied. The seller uses two-period dynamic price during the whole sale period and introduces quantity discount in second sale period in order to improve the seller’s profit. The mathematic model expressions are obtained by assuming that consumer’s reservation price draws from a uniform distribution and the price discou...
