Intro to Mathematical Economics

Definition

Computational methods refer to a set of numerical techniques and algorithms used to solve mathematical problems that are often too complex for analytical solutions. These methods play a crucial role in finding equilibrium points in economic models, especially when dealing with nonlinear equations or large systems. By leveraging computational power, economists can simulate scenarios and analyze data to better understand economic dynamics.
