B. consumers
5. The group that loses from free trade in this case is:
D. producers
6. A. net gain
7. The overall value of the gain is $2,000
Explanation:
a) Data and Calculations:
Area Before Trade After Trade Change
Value Value Value
Consumer Surplus
$? $? $?
Producer Surplus $? $? $?
Total Welfare $
? $? $?
Consumer surplus = Total quantity demanded at consumer's price minus equilibrium quantity * equilibrium price
Producer surplus = Total quantity supplied at supplier's price minus equilibrium quantity * equilibrium price
Change value at consumer surplus = $5,000 ($9,000 - $4,000)
Change value at producer surplus = $-3,000 ($1,000 - $4,000)
Total welfare before trade = $8,000 ($4,000 + $4,000)
Total welfare after trade = $10,000 ($9,000 + $1,000)
The net gain from free international trade is the difference between the total welfare value after trade and before trade = $2,000 ($10,000 - $8,000)
