(a) The Central Bank within the economy reduces interest rates.

(b) There is an increase in private domestic investment spending.

An increase in international oil prices.

Depreciation in the foreign exchange rate value of the economy's currency.

A fall in real estate prices in the capital cities of the country in question (hint: think of the effect upon one's wealth level)
