For the given in Problem 4, recalculate g with the following values of ti:
(a) ti = 20 percent.
(b) ti = 0.
(c) ti = 80 percent.
(d) ti = 100 percent.
In Problem 4
Calculate the rate of effective protection when t (the nominal tariff on the final commodity) is 40 percent, ai (the ratio of the cost of the imported input to the price of the final commodity in the absence of tariffs) is 0.5, and ti (the nominal tariff on the imported input) is 40 percent.
