Pemodelan Investasi Dinamis melalui Model AIGP: Evaluasi Stabilitas Sistem dan Perilaku Modal

Abstract

This study develops a financial dynamics model known as AIGP (Allocated Capital, Investment, Gain, and Portfolio), which represents the flow of capital within an investment system. The model is designed to analyze changes in capital allocation, investment activity, profit growth, and portfolio dynamics using a systems dynamics approach. By employing a set of differential equations, the study conducts stability analysis at equilibrium points and calculates the basic reproduction number to assess the potential for growth within the investment system. Numerical simulations are performed under various parameter scenarios to examine the system's sensitivity to changes in initial values. The results of this study are expected to provide a mathematical framework to support investment decision-making based on dynamic analysis.
