1a) Price elasticity of demand (PED) measures the degree of responsiveness of the quantity demanded of a good to a given change in price of the good itself‚ ceteris paribus. It is found by taking the percentage change in quantity demanded of good X divided by the percentage change in the price of good X. The numerical value of the price elasticity of demand is always negative due to the inverse relationship between quantity demanded and price as stated in the law of demand. When we interpret

Income Elasticity of Demand Income Elasticity of Demand is a measure of responsiveness of demand to the changes in income and it involves demand curve shifts. It provides information on the direction of change of demand‚ given a change in income and the size of the change. Formula for YED: Percentage change in quantity demanded = %ΔQ Percentage change in income %ΔY Normal goods have a positive value of YED‚ while Inferior goods have a negative value of YED as shown

Elasticity is a measure of how much buyers and sellers respond to changes in market conditions. There are 3 types of elasticity of demand‚ which are price elasticity of demand‚ income elasticity of demand and cross elasticity of demand. In general‚ elasticity of demand is important for a firm in price setting for its products. Price elasticity of demand is the percentage change in quantity demanded given a percent change in the price. It is a measure of how much the quantity demanded of a good

How would income elasticity of demand help explain these things ? Q ( Demand ) QS0 Superior QI1 QI0 Inferior QS1 Y1 Y0 Y ( Income ) During the decline in economy activity‚ the spending power will decrease which is similar as the decline in income. Home food which is economical are inferior goods while restaurant food which is much more costly are superior goods. Therefore from the income elasticity of demand curve‚ the demand for home food will

(a) (i) What is meant by ’cross-price elasticity of demand’? It is a measure of the responsiveness of demand for a good to a change in the price of another good. This good can either be a substitute good or complementary good. (ii) Comment on the cross-price elasticity of demand between platinum and gold. When the price of platinum rises demand for gold rises. Because gold can be a substitute for platinum people will want to buy gold more when the price of platinum increases. (b)
