Equilibrium Analysis is a method used in economics to study how supply and demand interact in a market. It helps determine the price and quantity of goods sold when the market is balanced, meaning that the amount of goods consumers want to buy equals the amount producers want to sell. This balance is known as market equilibrium. In addition to economics, Equilibrium Analysis can also be applied in other fields, such as chemistry and biology. In these contexts, it examines how different forces or reactions reach a stable state, where the rates of change are equal, leading to a consistent outcome over time.
