Two computer programs that simulate the multiplier and accelerator processes are described. The simulations can be used in college-level economics classes or by pupils using their own personal computers at home. Very little knowledge of programing is required to implement the simulations.

The principle of the multiplier-accelerator interaction is explained, and how a computer program to model it can be developed is shown. A series of simulations that can be used to explore the model's behavior are suggested. The simulations can be used in college-level economics classes. (Author/RM)
