About the exchange rate: RMB is fluctuating recently. In The 19th National Congress of the Communist Party of China, vice president of the People’s Bank of China Yi Gang pointed out that the RMB exchange rate mechanism is basically perfected, being very close to the market-oriented RMB exchange rate formation mechanism, and fluctuation is quite normal.

Findings: The increase in government spending reduces national saving, with domestic investment held constant, and thus lowering the supply of dollars to be invested abroad. The lower supply causes the equilibrium real exchange rate to rise and dollar becomes more valuable. Since the rise in the value of the dollar, domestic goods become more expensive relative to foreign goods, which causes exports to fall and imports to rise. The net exports thus reduce.
c) Now suppose that the world interest rate rises from 5 to 10 percent. G is again 1000. Solve for the national saving, investment, the trade balance and the equilibrium exchange rate. Explain what you find.
