Solutions

Expert Solution

1> In the short run, the entry of firms will result from postive profit

2> In the short run, the exit of firms will result from negative profit (loss)

3> In the long run, there will be zero economic profit.

4> Triple Equality is when Price =Marginal Cost = Marginal Revenue

5> The term productive efficiency means Price = Lowest point of ATC. This is important because it leads to optimal use of resources to produce output.

6> The term allocative efficiency means Marginal Utility= Marginal Cost. This is important because it equalizes supply and demand, thus there is no shortage or surplus.

Reason

In a perfect market, it is the case that firms will enter if they see there will be an economic profit by entering and will exit if they are losing money. Only when economic profit = 0, this stabilizes leading to no entry and exit. In perfect equilibrium, triple equality occurs, it makes sure that the outcome is productively and allocatively efficient.

In the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. Suppose firms announce the prices for their products in advance, based on an expected price level of...
