Figure 5-3. Using the midpoint method, between prices of $70 and $80, price elasticity of demand is about

3.00

If the price elasticity of supply is 0.6, and a price increase led to a 3.7 percent increase in quantity supplied, then the price increase is about

6.17 percent

Which of the following changes would not shift the demand curve for a good or service?

Figure 4-4. The movement from point A to point B on the graph is caused by

Table 5-2. Using the midpoint method, if the price falls from $160 to $210, the price elasticity of demand is

elastic

The terms equality and efficiency are similar in that they both refer to benefits to society. However they are different in that

equality refers to uniform distribution of those benefits and efficiency refers to maximizing benefits from scarce resources

Large or persistent inflation is almost always caused by

excessive growth in the quantity of money

Suppose the cross-price elasticity of demand between peanut butter and jelly is -2.50. This implies that a 20 percent increase in the price of peanut butter will cause the quantity of jelly purchased to

fall by 50 percent

gather data from historical episodes of economic change

Microeconomics is the study of
