It is log-linear which is the best fit to the data?
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
D. all of the above because all are not physical retailers. Non-traditional sellers/retailers do their selling/business over the phone, on the internet, etc.
Answer:
The correct answer is option d.
Explanation:
The effficent market hypothesis is an investment theory which advocates that the stock prices reflect all the available information. As a result, stocks are always traded at their fair value.
The strong form of efficient market says that stock prices reflect all information whether public or private.
This implies that investors cannot have more than normal profits. In the above example, the investors are able to make profit through insider information. This means that the market is less than strong form efficient.
The purchase of low-quality materials would most likely the result of a favorable materials price variance coupled with an unfavorable material usage variance. Material price variance is the difference between the cost and the budgeted and actual cost to obtain an object or materials, multiply to the total amount of the product purchased. They are what you called positive value of direct material price and negative value of direct material price. A positive value of direct material price variance is the one that is favorable and it means that the direct material was purchased for a lesser price than the standard price. A negative value of direct material price variance is the one that is unfavorable and it means that more than the expected price per unit is paid.
