1) An economy reallocates resources and moves along its production possibility frontier.
It increases production of necessity goods and reduces production of luxury goods.
The marginal utility of the consumers of the additional necessity goods produced is greater than
the marginal utility of the consumers of the luxury goods that are no longer produced.
What is the effect on the economic efficiency of the economy?
productive
efficiency
allocative
efficiency
A increases increases
B increases unchanged
C unchanged increases
D unchanged unchanged

1) There is no change in average cost hence productive efficiency remains unchanged. Since marginal utility gained from necessity goods is greater than luxury goods and production of necessity goods has increased, your allocative efficiency has improved.

8) The greater the number of goods you produced, the more your average fixed cost will decrease. This is because unlike variable cost, your fixed cost, also known as sunk cost, is shared among your produced goods. Hence your fixed cost decreases when output increases. Answer is D.

12) Revenue maximisation is when your MR=0. Marginal revenue means the additional revenue you gained from selling one additional output. When MR=0, you no longer receive anymore revenue, meaning you have maximised the revenue you can earn. Answer is B.
