3. Determinants of Demand Elasticities ~ Kmart and "Blue Light Specials"

Determinants which affect the degree of elasticity of demand include the elasticity of demand for a product (1) will be greater given the larger the number of substitutes, (2) the smaller the proportion of income or budget an item takes, (3) the item is a luxury or a non-necessity and (4) time, the consumer doesn't need the product right away.

K martalong with a variety of retailers, posts a weekly sales circular on selected merchandise. Kmart originally used the Blue Light Special, which began in 1965, for in-store sales promotion. Today, the Blue Light Specials are also available online. Kmart has decided that demand for these Blue Light Specials is elastic: the decrease in price will increase total revenue. Check out this week's specials and, for each item, score 1 point for meeting the criterion of each determinant above. How many specials score a 4? Do any score 0? Why would K mart include any item that scored less than a 4?
