You are advising a coffee shop manager who wants to estimate how much sales will change if the price of a latte rises. You tell him that he should measure the change in sales using the percentage change in quantity of coffee sold rather than the number of cups of coffee or the total ounces of coffee sold. Similarly, you tell him that he should measure the price increase in percentage terms rather than in terms of absolute dollars. Explain why he should measure elasticity in percentage terms rather than in terms of dollars and cups.

Expert Solution & Answer

To determine

To advise the coffee shop manager the reason for using percentage method to calculate the elasticity.

Explanation of Solution

The elasticity of demand indicates the change in quantity demanded due to a change in price. However, the elasticity is unitless that means only magnitude of change is considered for example elasticity could be 1, 1.5, 1.7, etc. Here, elasticity is just a magnitude (numeric value). Thus, while calculating the elasticity, the absolute values like, dollars, units (number of teacup) does not matter. So, using the percentage method avoids the problem of different units of calculation and the problem of direction to change. Thus, it is advised to the manager to estimate the change in percentage term.

Students have asked these similar questions

A gas station owner sees a report on TV which states that the number of gallons of gasoline sold in the U.S. has barely dropped, even as the price per gallon has soared in recent weeks. The price elasticity of demand for gasoline is described in the report as “highly inelastic”. The gas station owner responds to this report by jacking up the prices at his station by 50 cents per gallon. Sales and revenues at his station plummet in the first month after the price increase, and drop even further in the second month. What factors did this gas station owner fail to consider when he responded to the TV report by aggressively raising his prices?

Give two examples of elasticity information for two particular goods: one with an elastic demand and one with an inelastic demand.

Suppose a low-income family that earns K750 per month consumes 8 Kgs of Hamburgers and 2 Kgs of Beef in Month 1. However, in month 2 when the income of the family rises to K950, the quantity of Hamburgers consumed by the family reduces to 5 Kgs while the quantity of Beef increases to 4Kgs. What is the income elasticity of demand for hamburger? What is the income elasticity of demand for steak?
