Answer:
65 firms will be in the industry at the new long run equilibrium
Explanation:
in the long run the P=ATC
quantity before the change is
200 = 1000-4Q
4Q = 800
Q= 200
each firm output = Q/number of firms = 200 / 50
q = 4
new quantity is
200 = 1240-4Q
4Q = 1040
Q = 260
number of firms=new Q/q
=260/4 = 65
the number of firms is 65 in the long run.
Answer:
3
Explanation:
We are asked to use the midpoint formula.
Here, instead of dividing the change in values by the old value as in the normal elasticity calculation, we use the average of the two.
Mathematically:
Price elasticity of demand according to midpoint formula is :
{Q2 - Q1 / (Q2 + Q1) ÷ 2] × 100%} ÷ {[P2 - P1/ (P2 + P1) ÷ 2] × 100}
Price changed from 5 to 7. The midpoint of 5 and 7 is the average = (5+7)/2 = 6
% change in price in this case is (7-5)/6 * 100 = 100/3 = 33.33%
% change in quantity:
We first find the average = (12+4)/2 = 16/2 = 8
% change = (4-12)/8 * 100 = -100%
The elasticity of demand is thus -100/33.33 = 3
Answer:
(A) Because the regulation effectively reduced the price of cool air, consumers with sufficiently elastic demand might have bought substantially more of it.
Explanation:
If the demand for energy services remains constant, improving energy efficiency will reduce energy consumption and carbon emissions. However, many efficiency improvements do not reduce energy consumption by the amount provided by simple engineering models. This is because they make energy services cheaper and therefore increases the consumption of those services.
For example, since low-fuel vehicles make travel cheaper, consumers can choose to drive further, thus offsetting some of the possible energy savings. Similarly, an extensive historical analysis of improvements in technological efficiency has conclusively demonstrated that improvements in energy efficiency were almost always overcome by economic growth, which resulted in a net increase in resource use and associated contamination.
Answer:
(A) True
Explanation:
A corporation just requires a basic incorporation state, through which the legal identity of its incorporation is created. After that it does not require to incorporate in all the states where the business is being conducted.
As per the law, there shall be at-least a different legal identity then that of the individual to conduct such business. Law does not demand separate incorporation.
Thus, the above statement is
True.
