A small nation permits free trade in good X. At the good’s free-trade price of $8, domestic firms supply 6 million units and imports account for 3.2 million units. Recently, the small country has erected trade barriers with the result that imports have fallen to zero, price has risen to $10, and domestic supply has increased to 8 million units. Calculate the change in consumer surplus and producer surplus resulting from the trade barrier. What is the deadweight loss?
Hint: Write your answer to one decimal place.
he free trade price is = 8, Where Quantity supplied =6 Million and Imports =3.2 Million so Quantity demanded = 6+3.2 =9.2 Million
When the trade falls to zero it means that the price is equal to the domestic equilibrium price where the country's imports = 0 therefore,
After trade barriers, equilibrium Price =10
Quantity Supplied=Quantity Demanded =8 Million units
Consumer Surplus in free trade is denoted by the area C+D+E+F
CS decreases by area D+E+F after the trade barrier=
= 10-8* 8 million + 0.5*(9.2 million-8 million)*(10-8)
= 16 million + 1.2 million
= 17.2 million
Producer Surplus in free trade = area P
PS increases by area D after the trade barrier
= [ 05*(8 Million-6 Million)*(10-8)] + [(10-8)*6 Million ]
= 2M+12M = $14 Million
DWL is the area E+F
= 0.5*(8 million-6 million)*(10-8) + 0.5*(9.2 million-8 million)*(10-8)
=2 million+1.2 million
= 3.2 million

(8 points) A small nation permits free trade in good X. At the good's free-trade price of $8, domestic firms supply 6 million units and imports account for 4 million units. Recently, the smal country has erected trade barriers with the result that imports have fallen to zero, price has risen to $10, and domestic supply has increased to 8 million units. Calculate the change in consumer surplus and producer surplus resulting from the trade barrier. What is the deadweight...
Paradise is a small country that under free trade imports roses at $2.00 a dozen. Its domestic demand curve and domestic supply curve for roses are as follows: D = 100 - 10 P S = 10 + 10 P Calculate the equilibrium quantity imported under free trade. Under free trade: M = _________ If the government imposes a tariff of $1.00 on roses show graphically and calculate the impact of this tariff Graph: Under tariff: Domestic...
4. Consider the effect of a tariff in a small nation. Initially, under free trade the quantity supplied in a country is 24 units, the quantity demanded is 60 and the world price is $ 6 per unit. A tariff is introduced which raises the domestic price to $ 7 per unit. The elasticity of demand is -0.3 and the elasticity of supply is 0.5. Calculate the effects of the tariff on: producer revenue, consumer expenditure, the trade balance and...
4. 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: Q” = 8-P Supply: Q* =P where P is in dollars per bag and Q is in bags of jelly beans. a. Draw a well - labelled graph of the situation in Kawmin if the nation does not allow trade. Calculate the...
5. Problems and Applications Q5 The nation of Textilia does not allow imports of clothing. In its equilibrium without trade, a T-shirt costs $24, and the equilibrium quantity is 4 million T-shirts. One day, after reading Adam Smith's The Wealth of Nations while on vacation, the president decides to open the Textilian market to international trade. The market price of a T-shirt falls to the world price of $16. The number of T-shirts consumed in Textilia rises to 8 million,...

1. Reference: Ref 19-4 (9-4) (Figure: Foreign Trade with a Tariff) Refer to the figure. A $1 tariff results in: a. an increase in imports of 80 million units. b. a decrease in imports of 80 million units. c. an increase in imports of 100 million units. d. a decrease in imports of 100 million units. 2. In 1845, French economist Frédéric Bastiat famously compared tariffs to blocking out the sun since both low-priced imports and free sunlight discourage domestic...

multi part question 4. Agricultural export subsidies in a small nation The following graph shows the market for wheat in Canada, where Dc is the demand curve, Sc is the supply curve, and Pw is the free trade price of wheat. Assume that Canada is a relatively small producer of wheat, so changes in its output do not affect the world price of wheat. Also assume that Canada is currently open to free trade, and domestic consumers are able to...
