The developed simulation models are based on nonlinear differential equations that demonstrate different patterns of their solutions. The behavior of inflation exhibits various dynamic properties that substantially depend on initial state of economic environment and the values of parameters that describe economic conditions. The results of modeling revealed the bifurcation points and showed that the dynamic of price in economy could move unpredictable and represent different direction of movement even for small change in initial conditions. Moreover, it has been obtained that several equilibrium points in weak economic system are possible, which demonstrate different convergence properties. The price dynamics showed strong peculiarities of bifurcation depending on vicinity of equilibrium level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
