A group opposed to free trade concludes that the total number of domestic jobs will decrease because it estimates that 20,000 jobs will migrate abroad. The actual total loss is:
a) probably greater than 20,000 because of the tariff effect.
b) probably greater than 20,000 because of the multiplier effect.
c) probably equal to 20,000 because of the import effect.
d) less than 20,000 because the estimate ignores the jobs created in the industries that benefit from increased exports.
