Opis:
The main goal of this paper is to present a modern axiomatic approach to financial arithmetic. An axiomatic theory of financial arithmetic was first proposed by Peccati, who introduced an axiomatic definition of future value. This theory has been extensively developed in recent years. The proposed approach to financial arithmetic is based on the concept of the utility of a financial flow. This utility function is defined as a linear extension of a multicriterion comparison determined by an individual’s time preference and capital preference. The present value is then defined to be the utility of the financial flow. Therefore, the law of the diminishing marginal utility of wealth has been considered as an additional feature of the present value. The future value is defined as the inverse of the utility function. This definition is a generalization of Peccati’s one. The net present value is given as the unique additive extension of the utility of the financial flow. Moreover, the synergy effect and the diversification effect will be discussed. At the end, the axiomatic definition of the present value will be specified in three ways.

Opis:
A multi-asset portfolio in the case of its present value estimated by a discrete trapezoidal fuzzy number has been assessed. The benefits of owning a security have been evaluated according to an expected fuzzy discount factor. The ambiguity risk has been assessed by an energy measure and indistinctness risk has been evaluated by Kosko’s entropy measure. The relationship between the expected fuzzy discount factor for a portfolio and the expected fuzzy discount factors for its components has been derived. An analogous relationship between the values of the energy measure has been presented. The model has been illustrated by means of a profound numerical case study.

Opis:
We consider the obvious thesis that the present value of a portfolio is equal to the sum of the present values of its components. The main goal of this paper is the implementation of this thesis in the case when present values are determined by trapezoidal ordered fuzzy numbers. We apply the revised sum of ordered fuzzy numbers. The associativity of such a revised sum is investigated here. In addition, we show that the multiple revised sum of a finite sequence of trapezoidal ordered fuzzy numbers depends on the ordering of its summands. Without any obstacles, the results obtained can be generalized to the case of any ordered fuzzy numbers.
