Question
Kawmin is a small country that produces and consumes
jelly beans. The world price of jelly beans is
$1 per bag, and Kawmin’s domestic demand and
supply for jelly beans are governed by the following
equations:
Demand: QD = 8 − P
Supply: QS = P,
where P is in dollars per bag and Q is in bags of jelly
beans.
a. Draw a well-labeled graph of the situation in
Kawmin
if the nation does not allow trade.
Calculate
the following (recalling that the area of
a triangle is ½ × base × height): the equilibrium
price
and quantity, consumer surplus, producer
surplus
, and total surplus.
b. Kawmin then opens the market to trade. Draw
another graph to describe the new situation in
the jelly bean market. Calculate the equilibrium
price, quantities
of consumption and production,
imports, consumer surplus, producer surplus, and
total surplus.
c. After a while, the Czar of Kawmin responds
to the pleas of jelly bean producers by placing
a $1 per bag tariff on jelly bean imports. On a                      graph, show the effects of this tariff. Calculate
the equilibrium price, quantities of consumption
and production, imports, consumer surplus,
producer surplus, government
revenue, and total
surplus.
d. What are the gains from opening up trade?
What are the deadweight losses from restricting
trade with the tariff? Give numerical
answers.
