My last lesson

In my last lesson at school in economics we covered inflation. Inflation is measured by Retail Price Index but this has now changed to Consumer Price Index. There are two types of inflation: demand pull and cost push.
To reduce inflation the government may raise taxes and interest rates (Bank Of England) and cut spending. The easiest way to think of this is in terms of injections into the economy and with draws. Injections are government spending, investment and exports. Withdrawals are savings, tax and imports.
To reduce inflation: less injections more withdrawals
To reduce unemployment: more injections less with draws
To increase growth: more injections less with draws
Injections = G + I + X
Withdrawals = S + T + M
