Answer:
Under a) r=0.1;Id=50;Cd=750;P=7 b) P only changes and is now 9.33
Explanation:
a) In a closed economy national savings are equal to investments or:
S d = I d = Y - Cd - G
Id = Y - 100 - 0.8*Y + 500*r - 0.5*G
100 - 500*r = 0.2*Y -100 + 500*r -0.5*G
200 - 1000*r = 0.2*1000 - 0.5*200=100
-1000*r=-100
r= 0.1
i = 0.15
Id = 100 -50 =50
Cd= 100 + 800 - 50 - 100=750
P = Md/Y-2000 i
P= 2100/1000 -300=7
b) If money supply increases to 2800, the price level would be:
P = 2800/Y - 2000*i = 2800/Y- 2000*(i-inflation)
However, since the variables determining real interest rate remained the same, r is also the same or 0.1 and i is 0.15. Consumption and investment remain the same, only price level changes or:
P=9.33
Is this multiple choice...if so can you edit your question and put the answer options
I believe the answer is Time management
Promissory estopplel is a contractual agreement based on a promise rather than on a written contract but is still enforceable and legal such as in regarding payment for services rendered so that the contractor is protected financially.
Add the selections so I can answer.
