Answer:
A firm will wish to purchase its first permit if the price of that permit is less than or equal to:
$250.
Step-by-step explanation:
a) Data and Calculations:
Pollution tax = $250
Number of pollution permits to be sold = 100
Total pollution tax = $25,000 ($250 * 100)
b) The implication is that no firm would be prepared to pay per pollution permit more than the pollution tax. Instead, firms that would buy the 100 pollution permits would like to pay less than or equal to $250. The $250 is the price level that does not make any difference to their decision. However, the price option would become more attractive if it is less than $250 per permit.
