Answer:
The government policy should have reduced beer consumption by 0.6 or 60%
Explanation:
Mid point formula calculates the ratio of mid point of change in demand and change in price to their average value. Then these changes are used in the calculations of elasticity of demand.
According to given data:
Elasticity of demand = 0.9
Midpoint of price = (20-10) / [(20+10)/2] = 10 / 15 = 0.6667
Elasticity of Demand = Midpoint of demand / Midpoint of price
0.9 = Midpoint of demand / 0.6667
Midpoint of price = 0.9 x 0.6667 = 0.6
Change in demand is should reduce the consumption by 0.6 or 60%.
Answer:
B) 1,160.
Explanation:
First we must calculate planned aggregate expenditures (PAE) and then determine where Y = PAE:
PAE = consumption + planned investment + government spending + net exports = 100 + 0.75(Y - 40) + 50 + 150 +20 = 100 + 0.75Y - 30 + 50 + 150 + 20 = 290 + 0.75Y
Now we must determine where Y and PAE intercept:
Y = 290 + 0.75Y
Y - 0.75Y = 290
0.25Y = 290
Y = 290 / 0.25 = 1,160
*Planned aggregate expenditure = total planned spending, it differs from GDP because GDP includes unplanned investment.
PAE = C + Ip + G + NX while GDP = C + I + G + NX
If all firms only earn a normal profit in the long run, firms will develop new products or lower-cost production methods because they can innovate and possibly earn an economic profit in the short run.
Explanation:
Competition involves constant efforts by companies and executives to do more than the loss (normal gains) of new goods or by improving ways to manufacture current products at lower prices. Therefore, if businesses can invent, they will achieve short-term economic advantage.
Economic benefit encourages entry, economic losses lead to exit and firms in a highly profitable market earn little economic income in a long-term equilibrium. In an industry where inflation does not change the costs of materials (a market with a constant cost), the long-term supply curve is a horizontal line.
Answer:
C. Both (i) and (ii) are true
Explanation:
Under perfect price discrimination, consumer surplus doesn't exist since the supplier is selling the good or service at the maximum price that each consumer is willing to pay. This situation maximizes supplier surplus.
Under perfect competition, both supplier and consumer surplus exist.
Since total social surplus = supplier surplus + consumer surplus, total surplus should be the same in both situations.
