Gaining proficiency in managerial economics involves a lot of calculations. There are 3 elasticities of demand: price elasticity of demand (PED), cross elasticity of demand (XED) and income elasticity of demand (YED). Economists use the concept of price elasticity of demand to describe how the quantity demanded changes in response to a price change. If a product has many close substitutes, for example, fast food, then people tend to react strongly to a price increase of one firm's fast food. I have a data set with volume numbers at certain price points. To measure arc elasticity we take average values for Q and P respectively. Price Elasticity and Optimal Pricing Policy. Computing Price Elasticity (Warning: This section involves some simple algebra. P 2 this is the second price point. By calculating cross-price elasticity, we can measure the responsiveness and determine if the goods are substitutes, compliments, or not related to each other. We use the standard economics formula for calculating cross elasticity of demand relative to price. Most packages are compatible with Emacs and XEmacs. If a product has many close substitutes, for example, fast food, then people tend to react strongly to a price increase of one firm's fast food. To calculate elasticity, we will use the average percentage change in both quantity and price. Hence, price is the independent variable while quantity demanded is dependent.
