Dynamic Behavior of Economic Systems Over Time: Differential Equations

Abstract

The dynamic behavior of economic systems represents an emerging research area for contemporary economic systems. I found that static models, which are narrow in scope, do not include the fact that economies are constantly adjusting. So, to reach their equilibrium, we need the research on a dynamic model in economic behavior. The article presents the differential equations with economic concepts. These equations subsequently allow economists to describe the ongoing transformation of variables without having them in designated compartments or in blocks. Through examples, like the Solow growth model with Price Elasticities, and Market Price Adjustment Models, the paper discusses how even non-linear single differential equations with two or more variables can show feedback effects, stability, and long-term equilibrium, and supply efficiency. The analysis consists of both positive and negative aspects of mathematical models. They also represent the nature of stability and change. The essay concludes that differential-equation models that are simplified for high-school mathematical skills still have their value, and in fact, they provide useful methods for linking theories and real-world phenomena. Such models could work as a starting point for the more advanced dynamic economic models and policy experiments thereafter.
