Question 4 – 15 marks (MICROECONOMICS):

Part A:  Answer the following questions.

Korea imports a large quantity of beef. With no beef trade, Korea’s equilibrium price for beef was $8 million per kilo tonne and equilibrium quantity was 375 kilo tonne. If Korea opens its beef market to trade with no tariff, domestic demand would be 625 kilo tonne and domestic supply would be 125 kilo tonne at the world price of $4 million per kilo tonne. However, Korea currently imposes 40 per cent tariff rate on all imported beef. With 40 per cent tariff, Korea’s domestic supply and domestic demand were 250 kilo tonne and 500 kilo tonne respectively in 2013. Assume that intercept of supply curve is $2 million and demand curve is $15 million per kilo tonne.                                  



(a)      Analyse the effects of 40 per cent tariff rate on the price of beef in Korea and Korea’s beef imports in comparison with no tariff case. Provide numeric details.  (2 marks)






(b)     Draw a graph and clearly show how the areas of gains and losses from the trade with 40 per cent tariff rate would change before and after the tariff with brief explanation. Then, calculate the actual value of change in consumer surplus, producer surplus, tariff revenue and the amount of deadweight loss.  Show your calculation.  (8 marks)













Part B:  Answer the following question.
