overall demand for iPods. Price elasticity is a tool designed to identify the overall change in demand or supply of a product compared to the overall movement of price. For the sake of this paper‚ we will focus on the overall change in demand from consumers. Elasticity is calculated by creating a ratio of the percentage change in demand of a good compared to the percentage change in price.

The firm is able to charge the maximum possible price for each unit which enables the firm to

Price takers are defined as “Sellers who must take the market price in order to sell their product (Gwartney‚ Stroup‚ Sobel‚ Macpherson).” The price takers production is very small compared to the total market; this allows the price takers to sell their products at the market price. However‚ they can’t sell any of their products at a higher price relative to the market price. To better explain; the text states In a price-taker market‚ the firms all produce identical products (for example‚ wheat
