Answer:
<em>Face validity</em>
Explanation:
Face validity applies to the great extent in which an evaluation or measure tends to subjectively assess the component or construct to be measured.
In certain utterances, face validity is when an evaluation or test happens to be doing what it claims to be doing.
Answer:
d. downward and cause output to decrease
Explanation:
As we know that
Aggregate demand = Consumption expenditure + government expenditure + net export
Where,
Net export = Export - import
In the case when there is a reduction in the consumer spending so it would be expected that the aggregate demand curve would be shifted to the downward due to which it results in reduction in output
Therefore the option d is correct
Answer:
(d) all costs exclusive of payments to fixed factors of production.
Explanation:
The cost involved in the first three options is considered by economists as accounting cost. Economic cost involves the accounting cost, but it is added to the opportunity cost, which is the remuneration that an economic agent fails to receive for practicing one economic activity and not another.
For example, a business owner has fixed production costs, but it should add to his opportunity cost to be working in that firm rather than another economic activity.
Answer:
1. Y = 3730
2. Consumption function
Explanation:
1. Given that,
C = 140 + 0.9 (Yd)
T = 0.3Y
Yd=Y-T
I = 400, G = 800, X = 600, M = 0.15Y
Y = C + I + G + (X - M)
Y = 140 + 0.9 (Y - 0.3Y) + 400 + 800 + (600 - 0.15Y)
Y = 140 + 0.9 Y - 0.27Y + 1,800 - 0.15Y
Y = 1,940 + 0.48Y
Y - 0.48Y = 1,940
0.52Y = 1,940
Y = 3,730.76 or 3,730
2. C = 210 + 0.8 (Yd) is a consumption function.
