When a firm changes prices‚ the effect on profits is more important than the effect on revenue. There is a simple formula to calculate the critical Price Elasticity of demand which is just sufficient to maintain the contribution to overheads and profits. This will be greater than that required to maintain revenue. A common issue in business and in business studies is whether a firm should change the prices at which products are offered. The calculations begin with estimates of the reaction of

1. When the price of corn was "low‚" consumers in the United States spent a total of $8 billion annually on its consumption. When the price halved‚ consumer expenditures actually DECREASED to $6 billion annually. This indicates that: A. The demand for corn is elastic. B. The demand curve for corn is upward sloping. C. Corn is a Giffen good. D. The demand for corn is inelastic. Solution: C. Corn is a Giffen good. Giffen goods are an exception to the Law of Demand. Contrary to the Law

ELASTICITY It shows the degree of responsiveness of the change in the one variable due to the change in the quantity of the other variable. Elasticity = Percentage change in the one variable Percentage change in the other variable It is simply a way of quantifying cause of and effect relationship. The concept of elasticity can be used in demand and supply. ELASTICITY OF DEMAND We can study the elasticity of demand under the following categories. Price elasticity

9 – Elasticity and Demand Demand and Elasticity Elasticity is a way to measure the responsiveness of a dependent variable to changes in an independent variable. Elasticity is defined as a ratio of the percentage change in a dependent variable to a percentage change in an independent variable.
