The price elasticity of demand for imported whiskey is estimated to be −0.20 over a wide

interval of prices. The federal government decides to raise the import tariff on foreign
whiskey, causing its price to rise by 20 percent.
a. Will the quantity demanded on imported whiskey rise or fall, and by what percentage
amount?
b. What is the percentage change in the total revenue after the tariffincreases?

Sales of whiskey will fall by 4%. Finding the solution to this problem is simple algebra. The equation for the price elasticity of demand is Elasticity=%Change Quantity Demanded / %Change Price

Therefore, we just plug in the figures we are given and solve for % Change Quantity Demanded
-.2 = X / .2
Multiple -.2 by .2 and we get -.04 which is 4% which is the % Change in Quantity Demanded

a. Well, when the price of imported whiskey rises by 20 percent, and considering the price elasticity of demand is -0.20, the quantity demanded will actually fall. Since the price elasticity is less than 1 in absolute value, we can expect a decrease in quantity demanded. As for the percentage amount, I'm sorry, but my calculator is off duty today.

b. Ah, the total revenue after the tariff increases! This calls for some math humor. The percentage change in total revenue can be found using the formula:

%ΔTR = %ΔQ + %ΔP

where %ΔQ is the percentage change in quantity and %ΔP is the percentage change in price. Since we already know the percentage change in price is 20 percent, we need to determine the change in quantity demanded. And since the price elasticity of demand is -0.20, we can use the formula:

%ΔQ = (%ΔP) * (Elasticity of demand)

Whoops! Sorry for throwing math at you there. Long story short, the percentage change in total revenue will depend on the magnitude of the change in quantity demanded. So, without knowing that, I can't give you an exact number. But don't worry, I won't leave you hanging like an unfunny joke.

a. According to the price elasticity of demand, a negative value (-0.20) indicates that imported whiskey is inelastic. When the price increases by 20 percent due to the import tariff, the quantity demanded is expected to fall.

To determine the percentage change in quantity demanded, we can use the formula:

Percentage change in quantity demanded = (Price elasticity of demand) x (Percentage change in price)

Substituting the values:
Percentage change in quantity demanded = (-0.20) x (20%)
Percentage change in quantity demanded = -4%

Therefore, the quantity demanded will fall by 4%.

b. To calculate the percentage change in total revenue, we need to consider the price effect and the quantity effect.

The price effect occurs when the price increases, increasing the revenue per unit sold.

The quantity effect occurs when the quantity demanded decreases in response to the price increase, reducing the total number of units sold.

Since the demand is inelastic (-0.20), the price effect will dominate the quantity effect, and total revenue will increase.

The percentage change in total revenue is the sum of the percentage change in price and the percentage change in quantity demanded:

Percentage change in total revenue = Percentage change in price + Percentage change in quantity demanded

Substituting the values:
Percentage change in total revenue = 20% + (-4%)
Percentage change in total revenue = 16%

Therefore, after the tariff increase, the total revenue is expected to increase by 16%.

To answer these two questions, we can use the concept of price elasticity of demand. Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.

a. To determine the percentage change in quantity demanded, we need to know the price elasticity of demand. In this case, the price elasticity of demand for imported whiskey is given as -0.20. Since the price of imported whiskey is expected to rise by 20 percent, we can calculate the percentage change in quantity demanded using the formula:

Percentage change in quantity demanded = Price elasticity of demand * Percentage change in price.

Percentage change in quantity demanded = -0.20 * 20 = -4%.

Therefore, the quantity demanded of imported whiskey will fall by 4% when the price increases by 20%.

b. To calculate the percentage change in total revenue, we need to consider the impact of the change in price on quantity demanded. In a simplified scenario, when price and quantity move in opposite directions, the change in total revenue can be estimated using the formula:

Percentage change in total revenue = (Percentage change in quantity demanded) + (Percentage change in price).

Percentage change in total revenue = -4% + 20% = 16%.

Therefore, the total revenue is expected to increase by 16% after the tariff increases.

Please note that this calculation assumes that price and quantity demanded have a linear relationship and there are no other factors affecting demand. In reality, the actual impact on quantity demanded and total revenue may be influenced by various other factors.
