1Cademy - An economic model is created to predict how a 10% increase in the price of coffee beans will affect the number of cups of coffee sold at a local café. The model assumes that consumer income, the price of tea (a substitute), and the cafés advertising budget all remain unchanged. If, in reality, a major local employer lays off hundreds of workers at the same time the coffee bean price increases, the models prediction will likely be inaccurate. How does the holding other things constant assumption help economists understand this situation?

An economic model is considered flawed and useless if its predictions do not perfectly match real-world outcomes because it failed to account for every possible influencing factor.
