Explanation / Answer

3.

A.

In the short run, the profit of the sushi restaurant will increase and the sushi restaurant will earn the positive economic profit. After seeing this, the new sushi restaurants will join the industry. Hence, in the long run, more sushi restaurants will operate to cater the consumers and economic profit will become zero. At his point, the long term equilibrium will be established. So, the first sushi restaurant will not be able to sustain the profit, earned in the short run to the long run.

B.

Now, the local steakhouses suffer the losses and the price will become lower than the cost or even lower than the variable cost. It will cause the negative economic profit. As a result, local steakhouse firms will exit the industry in the long run. It will drive economic profit back to zero and long run equilibrium is established.
