Macroeconomics

Macroeconomics studies large-scale economic decisions. For example, a whole country's economy is summarised by the GDP (gross domestic product). Many governments use macroeconomic ideas to decide how much tax to collect, and what interest rates should be.

It also considers the amount of unemployment, the rate that prices go up (inflation), and the exchange rates of its currency. The exchange rate affects the amount of imports and exports. Exchange rates and taxation are "levers of the economy".

Less dramatic, but also very important, are decisions about government spending inside the country. Always there is more need than there is money to spend, and decisions are politically controversial. Another factor in macroeconomics is the make-up of the population. A growing population is economically different from a stable population (one which is not growing).
