Answer:
a. positive, so Joan considers hamburger to be an inferior good.
Explanation:
Income elasticity is a microeconomic concept that aims to measure the sensitivity of demand in the face of income changes. To calculate the Income elasticity , a formula is used that divides the observed percentage change in quantity (Q) by the percentage change in price income (P): Elasticity = ▲ Q / ▲ P
The percentage change in quantity (▲ Q) and the percentage change in price (▲ P) are calculated by the difference in quantity / price in the two periods divided by the quantity / price of the first period.
▲ Q = (60 -50/60) = 0,16
▲ Q = (40.000 - 30.000/40.000) = 0,25
Elasticity = ▲ Q / ▲ P = 0,16/0,25 = 0,64
Therefore, the elasticity is positive.
This good is considered inferior, because according to microeconomic theory, inferior goods are those whose demand increases when consumer income decreases. This is the opposite of the normal good, which has its demand increased when income increases.
Answer: (A) inelastic
Explanation: In inelastic demand it states that by increasing the cost price it will create a proportionality in the total revenue ,that is revenue will also increase.In this case the demand of the buyer does not change, only the cost changes and the consumer will keep on buying the goods even after change in price.
Opera Estate Girls' School is also using this technique to increase the revenue,by increasing the tuition.Thus the correct option is option (A).
Answer:
B) –2%
Explanation:
The total return on an investment is calculated by,
Total Return = Capital gains ÷ Initial Investment x 100
First we will have to calculate capital gains of his investment,
He got 600 in dividends and 4,300 after selling the stock against the initial investment of $5,000.
So capital gains,
= 600 + 4,300 - 5,000
= -100
Total Return would be,
= -100 / 5,000 x 100
= -2% is the total return on his investment.
Answer:
A. The USA specializes in potatoes because of its comparative advantage in producing potatoes.
Explanation:
US 1 ton of potatoes or 0.5 tons of wheat = 2
Ireland 3 tons of potatoes or 2 tons of wheat = 1,5
Answer: A. the 99 principle
Explanation:
This strategy, often called "charm pricing," involves using pricing that ends in "9" and "99."
With charm pricing, the left digit is reduced from a round number by one cent. We come across this technique every time we make purchases but don’t pay attention. For example, your brain processes $3.00 and $2.99 as different values: To your brain $2.99 is $2.00, which is cheaper than $3.00.
How is this technique effective? It all boils down to how a brand converts numerical values. In 2005, Thomas and Morwitz conducted research they called "the left-digit effect in price cognition." They explained that, “Nine-ending prices will be perceived to be smaller than a price one cent higher if the left-most digit changes to a lower level (e.g., $3.00 to $2.99), but not if the left-most digit remains unchanged (e.g., $3.60 to $3.59).”
