(b) There is an increase in private domestic investment spending.
(c) An increase in the good and services tax (GST)
(d) An appreciation in the foreign exchange rate value of the economy’s currency.
(e) A fall in real estate prices in the capital cities of the country (hint: think of the effect upon one’s wealth level)
(f) The country’s main exports fall in price while the goods the country imports from abroad rise in price (3 marks)

9 The central bank decides to implement an expansionary policy action. What would you expect to happen to the nominal interest rate, the real interest rate and the money supply and credit growth? Under what economic circumstances would this type of policy action be appropriate? (2 marks)
