Economic dynamics, uncertainty and fuzzy differential equations
Abstract
In the economic analysis is used the term dynamics to refer to an analysis whose objective is to trace and study the time trajectories of the variables, as well as determine if these will tend to converge to certain equilibrium values after a while.
The introduction of time explicitly in the formulation of problems can be done as a continuous or discrete variable. Its use will depend on the context in which the situation to be studied is immersed.
In this paper the case of continuous time and uncertain environment is considered, so second-order linear differential equations with fuzzy constant coefficients will be used to solve two classic problems of economic dynamics in situations of uncertainty. Vagueness will be represented by triangular fuzzy numbers.
Fuzzy sets allow us to understand that everything is a matter of degree, which makes it easier to adjust to reality, to process, not only certain and random data, but also information based on perceptions, sensations and expectations.
