T/F/Explain

Price elasticity of demand is measured using the slope of the demand curve.

2.

Our company, Slim ‘N Trim, Inc. sells pants for $40 a pair. After a successful year, you decide to try raising the price to $60. Your observation: sales drop from 50 pairs to 40. What is your price elasticity of demand calculated using the midpoint formula?

3.

After observing the value of your elasticity, does increasing your price increase, decrease, or have no effect on your total revenue? Why?

Expert Solution

1. True.

The reason being that the price elasticity of demand is or where is the slope of the demand curve.

2. The price elasticity of demand would be , and for the given values, we have or or or .

3. The demand elasticity in previous part is less than 1 (in absolute value), meaning that the demand is inelastic. The interpretation would be that, for a unit percent increase in price, the demand is decreased by 0.5556%. Judging from the elasticity, we may say that, if the price is increased, the quantity would decrease less than the increase in price, meaning that the increase in price would more than offset the decrease in quantity, and hence, the total revenue would increase.

We may match this observation by the data given. The TR before was and the TR after is . As can be seen, the revenue indeed increased.

The price elasticity of demand equals the slope of the demand curve. t/f

can you help me with these microeconomics t/f questions.The price elasticity of demand equals the slope of the demand curve. t/fthe larger the portion of a persons total budget spent on a good, the more inelastic the demand for the good. t/fif the demand for farm products is income elastic; that would mean that farm products were necessity. t/ffor hockey memorabilia fans, the puck with which Sidney Crosby scored the Golden Goal in 2010 is perfectly elastic In supply. t/fif...

1) The absolute value of price elasticity of demand for a linear demand curve (constant slope) follows the pattern (moving from high prices to low prices along the demand curve) a. constant. b. increases. c. decreases. d. has no pattern (of changes). 2) Given a demand function P=20–0.2Q. The own-price elasticity at (Q=25, P=15) is a. -1. b. -2. c. -3. d. -4. 3) A market has only two consumers: A and B. Consumer A has a demand function given...

True or False: The value of the price elasticity of demand is equal to the slope of the demand curve.

4. Elastic, inelastic, and unit-elastic demand The following graph shows the demand for a goodFor each of the regions listed in the following table, use the midpoint method to identify if the demand for this good is elastic, (approximately) unit elastic, or inelastic. True or False: The value of the price elasticity of demand is equal to the slope of the demand curve.

True or False: The value of the price elasticity of demand is not equal to the slope of the demand curve.
