Answer:
Katie Kwasi's Utility Function
The units of x1 that she will consume after the change in income is:
= 40 units of x1
Explanation:
a) Data and Calculations:
Katie Kwasi’s utility function, U(x1, x2) = 2(ln x1) + x2
Current consumption = 10 units of x1 and 15 units of x2
When her income doubles, with prices staying constant, Katie will consume:
= 2(2 * 10 of x1) + 15 of x2
= 40 units of x1 + 15 units of x2
Therefore, she will consume 40 units of x1 and 15 units of x2
b) The above function expresses mathematically Katie's utility to be a function of the units of x1 and x2 that she can consume, given her income constraint. If her income doubles, Katie will consume double units of x1 and the same units of x2 as she was consuming before the change in income.
Taxes are automatically withdrawn from paychecks.
Answer:
Explanation:
United States is producing 200 tons of hamburgers and 60 tons of tacos.
United States' opportunity cost for producing 1 ton of hamburgers
= 
= 0.3
United States' opportunity cost for producing 60 tons of tacos.
= 
= 3.33
So we see that US has a lower opportunity cost in producing hamburgers, so it has a comparative advantage in producing hamburgers.
Mexico is producing 40 tons of hamburgers and 50 tons of tacos.
Mexico's opportunity cost of producing a ton of hamburgers
= 
= 1.25
Mexico's opportunity cost of producing a ton of tacos
= 
= 0.8
So we see that Mexico has a lower opportunity cost in producing tacos, so it has a comparative advantage in making tacos.
Since US specializes in making hamburgers, it will produce 200 tons of hamburgers and 0 tons of tacos.
Mexico specializes in making tacos, it will produce 50 tons of tacos and 0 tons of hamburgers.
Answer:
When a financial friction is added to the short-run model it: shifts the MP curve up.
Explanation:
The short-run model, IS/MP model, describes the Investment-Savings/Monetary Policy model used by the US Federal Reserve to decrease the real interest rate through the Federal Funds rate, i.
The Federal Funds rate is the interest rate that commercial banks with excess reserves lend to others in deficit. The resulting shift occasions a decrease in the real interest rate which triggers an increase in the inflation rate, and vice versa. With such short-run changes in the interest rate, inflation and output is influenced in desirable directions by the Federal Reserve as a foundation to achieve long-term shifts in the AD-AS model.
The AD-AS model is a long-term model that describes Aggregate Demand and Aggregate Supply which impact long-term inflation, interest rates, and output.
<u>Explanation:</u>
A. This is the case of Cyclical unemployment here lorraine is just graduated and does not find any job inspite of applying with many of the employers. Here the economic condition of the country is below its full capacity.
B. It is example of potential frictional unemployment as George takes time to move on from current job to a part time job. Frictional unemployment is the time taken to move from one job to another.
C. This is an example of structural and technological unemployment as there is a mismatch between the labor market required skills and the skills of the candidate. Christine has bank teller skills but it is not matched with skills expected by banks.
D. It is called as frictional unemployment where Ricardo is out of job due to lay off by the company. The period between a jobless situation and job is frictional unemployment.
