II . Exercise 1 In the model of two countries ( 1 , 2 ) and two products ( X , Y ) : Country 1 has a productivity of 6X and 4Y ( hour / person ) ; Country 2 has 1X and 2Y productivity (hours/person); The exchange rate is 6X = 6Y. a . Compare the additional benefits of two countries when trading with each other ( 1 pt ) b . Define the framework of trade exchange between two countries. ( 1 pt ) Exercise 2 The data is given in the following table : Labor Productivity Country 1 Country Product A ( product hour worked Product B ( product per hour ld ) country 2 4 Determine : a . and patterns of international trade between two countries ( 0.5 d ) b . At what exchange rates would trade between two countries not occur ? ( 1.5 d ) c If two countries did exchange with each other in the ratio 4A = 5B, how much time will be saved? ( 1 pt ) Exercise 3 There are documents given in the following table : 4 Product | Country 1 | Country 2 X ( time Id / sp ) Yigid Id / sp ) 3 Each country has a total resource of 1200 hours of labor and 50 % for each product when closed . a . Determine the size of production and consumption when the two countries are economically closed. ( 0.5 dong ) b . Determine the commercial basis , TM model and TM conditions of the 2 countries . ( 1.5 dong ) c . For which trade condition domain, country 1 is more profitable than country 2? ( 0.5 dong ) d . Determine the production and consumption benefits of the 2 countries from full specialization and trade in the quantities 2000 , 200Y . ( 1.5 dong ) In QG1 , 1 hour of labor is paid £8 , country 2 pays 10 $ . Determine the prices of X and Y in the two countries and the exchange rate range of the two currencies for trade between the two countries to occur according to the above model. ( 1 dong )
