Explanation / Answer

1).

According to the “Marshall-Lerner” condition the sum of “import and export elasticity” must be more than “1”. So, under this condition “real devaluation” leads to improve the “trade balance”, => “Net export” will improve.

So, here the correct answer is “increase in real exchange rate” or “real devaluation of exchange rate”. So, here the correct option is not given.

2).

Similarly, with the same logic the “NX” will improve as a result of “increase in real exchange rate”, => correct option is “B”.

3).

Now, the national income identity is given by, “Y = C+I+G+NX”, where “NX=CA”.

=> Y = C+I+G+CA, => Y-C-G = I+CA, => (Y-T-C)+(T-G) = I+CA, where “(Y-T-C)+(T-G)” is national savings and “(Y-T-C)” is private saving of a home country. So, here the correct answer is “none of the above”. So, the correct option is “E”.

4).

Suppose the policy maker wants to increase “Y” and increase “NX”. As we know that “Y” is sum of “C+I+G+NX”. Now, “NX” is the function of “Y*, e”, where “Y*” be the foreign income and “e” be the “real exchange rate”, => as “e” increases, => “make export cheaper” and import expensive, => “NX” will increase. So, as “e” increases implied “NX” also increases which intern increase “Y”, => the correct option is “B”.

5).

Now, the interest parity condition is given by, “(1+i) = (1+i*)*(Eet/Et+1)”, where “E” be the exchange rate. So, here as “i*” decreases implied for each given “i", “i*” decreases, => the interest rate parity curve will shift right side and get flatter. So, here the correct answer is “D”.
