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.
Solution:
Given ,
1 Year interest rates in Europe = 4 %
1 Year interest rates in the U.S. = 2 %
You are translating $200,000 and spending $200,000 in French
Current spot rate of the euro = $1.20
a. (2%-4%)/(1+4%)=(S - 1.20) / 1.20
S= $1.1769 one year Euro rate
b. ( $1 / 1.20 )( 1 + 4% )* 1.12 = $.9707 return of -2.93% (loss)
c. ( $1 / 1.20) ( 1 + 4%)* 1.31 = $1.1353 return of 13.53% (gain)
d . ($1 / 1.20) ( 1 + 4%) *S = $1 (1+2%) ;
S=$1.1769
A spot rate of over $1.17697 (this is the same in part A) would be effective.
Answer:
Consumer surplus increases by $2
Explanation:
The consumer surplus can be defined as the benefit that consumers gain when they pay less for a good that they are willing to pay more for.
a). Determine the final demand as follows;
Price elasticity of demand=% change in price/% change in demand
where;
price elasticity of demand=-1
% change in price={(Final price-initial price)/initial price}×100
Final price=$24
initial price=$25
% change in price=(24-25)/25=(1/25)×100=-4%
% change in demand=x
replacing in the original expression;
-1=-4/x
x=4%
% change in quantity={final quantity-initial quantity/initial quantity}×100
let final quantity=y
4%={(y-100)/100}×100
0.04=(y-100)/100
4=y-100
y=4+100=104
final quantity=104 units
Consumer surplus=(1/2)×change in price×change in quantity
where;
change in price=25-24=1
change in quantity=104-100=4
Consumer surplus=(1/2)×1×4=2
Consumer surplus increases by $2
Answer:
Each grilled cheese costs $1.25
Explanation:
Giving the following information:
Her income is $50 a week. Hamburgers cost $4, and she consumes 10 of them. She consumes eight grilled cheese sandwiches.
To calculate the price of the grilled cheese sandwiches, we need to use the following equation:
Income= cost of hamburgers*number of units + cost of grilled cheese*number of units
50= 4*10 + x*8
10=8x
$1.25= x= grilled cheese
