Elasticity vs. Slope as a Measure of Price Responsiveness
The slope of the demand function (dQ/dP) is not an ideal measure of price responsiveness, as its value is dependent on the units used to measure price (P) and quantity (Q). For example, the slope's numerical value would differ if prices were measured in euros versus dollars. Price elasticity, by contrast, provides a more effective measure. Since it is calculated from proportional changes, elasticity is a unitless metric, meaning its value remains constant regardless of the units of measurement for either price or quantity.

A pharmaceutical company and a local gourmet coffee shop both increase the price of their flagship products by 10%. The pharmaceutical company sells a patented type of insulin, a life-saving medication for which there are no direct substitutes. The coffee shop sells a popular specialty latte, for which there are many alternative beverage options nearby. Based on the principles of consumer responsiveness to price changes, which of the following outcomes is most likely?
A local movie theater raises its ticket price by 15%. In response, the number of tickets sold per week decreases by 30%. Based on this information, how would you characterize the consumer demand for movie tickets at this theater?
Consider a standard, downward-sloping, straight-line demand curve. As one moves from a high-price, low-quantity point down along the curve to a low-price, high-quantity point, what happens to the slope of the curve and the price elasticity of demand?
A company's market research team determines that the demand for its flagship product is price inelastic. The company's primary goal is to increase its total revenue. Based on this information, which pricing strategy should the company implement?
Two distinct, downward-sloping linear demand curves, D1 and D2, intersect at point E. At this point, curve D1 is steeper than curve D2. Which of the following statements is true regarding the price elasticity of demand at point E?
The slope of a demand curve is a more reliable measure of consumer responsiveness to price changes than the price elasticity of demand because the slope's value is constant along a straight-line demand curve.
Analyze the characteristics of each product listed below and match it with the description that best explains its likely price elasticity of demand.

A market analyst for an international coffee company first measures the demand for their product with price in US dollars ($) and quantity in pounds (lbs). At the current market price, they calculate both the slope of the demand curve and the price elasticity of demand. The company then decides to standardize its reporting for European markets and re-measures the same demand relationship with price in Euros (€) and quantity in kilograms (kg). How will the newly calculated values for slope and elasticity at the exact same market equilibrium point compare to the original values?

Comparing Measures of Price Responsiveness
An economist observes that the slope of the demand curve for gasoline is -0.5 (gallons per dollar) while the slope of the demand curve for coffee is -2 (cups per dollar). Based solely on this information, the economist can conclude that the quantity demanded of coffee is more responsive to a change in its price than the quantity demanded of gasoline.
Evaluating Measures of Price Responsiveness
Consider a straight-line, downward-sloping demand curve. As one moves from a high-price, low-quantity point down along the curve to a low-price, high-quantity point, what happens to the slope of the curve and the price elasticity of demand?
Match each characteristic below to the appropriate measure of price responsiveness.
An international beverage company analyzes its sales data. In the United States, the slope of the demand curve for its soda is -500 cans per dollar. In Japan, the slope is -20,000 cans per yen. A manager concludes that demand is far more responsive to price changes in Japan than in the US. Why is this conclusion likely invalid?
Because price elasticity of demand is calculated using percentage changes, its value is independent of the units used to measure price and quantity, making it a ____ measure.
