Elasticity is related to a firm's total revenue and changes as you move up and down the demand curve. Suppose you are a marketing manager charged with deciding whether to increase the price of goods. The company's goal in considering that decision is to increase total revenue. If you were facing elastic demand, would a price increase be a good way to increase total revenue? If you were facing inelastic demand, would a price increase be a good way to increase total revenue? Since elasticity changes as you move up and down the demand curve, how can the marketing manager know whether demand for a product is elastic or inelastic?
