Week 4 elasticity, tax incidence and tax burden. A key characteristic of demand and supply curves! Changes in one variable as another variable changes. Answer is given by the elasticity of supply of tomatoes in ontario. Ed = dq/dp x p/q = (dq / q) / (dp / p) Ed = percentage change in quantity demanded percentage change in price. how consumers respond to a change in market price. Es = percentage change in quantity supplied percentage change in price. How producers respond to a change in market price. Ed = dq/dp x p/q = 1/(-1) x 20/80 = . It means that if p = and the price changes by 4%, we expect that the quantity demanded will change by about 1%. (why about ?) Demand is unit(ary) elastic if ed = 1. Think about relation between consumers" total expenditure on a product and the price that firms charge to customers. (it depends on the elasticity of demand).

From the scenario for Katrinaâs Candies, examine the procedure Herb will use to estimate the "demand model" for this product and comment on the expected price elasticity, income elasticity, and cross price elasticity of demand. That is, do you expect demand to be price elastic or inelastic? Will the income elasticity suggest Katrina Candies is a luxury or a necessary good? And, is there likely to be a strong cross price elasticity with the other products that Herb included in his demand model? Explain your answers. What can you determine about consumer demand for a product whose estimated demand elasticities are as follows: Price Elasticity of demand is -0.85 Income Elasticity of demand is 2.5 Cross Price Elasticity of demand with this product and your product is -2 I would like you to think about this simple formula for predicting the change in total revenue when there is a given percentage change in price. Using the example above, if ED (price elasticity of demand) is -.85, then a 10% increase in price will cause the quantity demanded to fall by 8.5%, (-8.5% / 10% = -.85). The Formula for Predicting % Changes in Total Revenue is: %ÎTR = %ÎQ + %ÎP where TR = Total Revenue, Q is Quantity Demanded and P = price. Using this formula, what would be the % Î in TR if ED is -.85 and the %ÎP is 10%?

Discussion #1

The law of demand states that a fall in the price of a good raises the quantity demanded, and the increase in price leads to a decrease in quantity demanded. The price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. Demand for a good is said to be elastic if the quantity demanded responds substantially to changes in the price, and the percentage change in quantity demanded is greater than the percentage change in price. Demand is said to be inelastic if the quantity demanded responds only slightly to changes in the price, which indicates that the percentage in price is greater than the percentage in quantity demanded.

However, the extent of responsiveness of quantity demanded to a change in price depends on the nature of a particular good or service in the market. The price elasticity of demand partly depends on the availability of close substitutes. When a large number of substitutes are available, consumers respond to a higher price of a good by buying more of the substitute goods and less of the relatively more expensive good. In addition, goods or services that are considered necessities tend to have less elastic (more inelastic) demand, whereas goods or services that are considered luxuries have more elastic (less inelastic) demands.

Explain why the demand for the good or service provided by the organization you work for is elastic or inelastic. How does this influence pricing decisions?
Provide examples on how the availability of close substitutes affects price elasticity of demand.
Give specific examples of necessities or luxuries, and explain how they affect price elasticity of goods or services.
