disinflation

a falling rate of inflation; prices are still rising but by not as much

hyperinflation

when the rate of inflation is high and accelerating, to the extent that it is out of control

inflation

the general rise in prices of goods and services that erodes the purchasing power of money

Retail Price Index (RPI)

how the flow of assets is spread throughout the economy

income inequality

when income is unevenly distributed across a nation

wealth distribution

how the stock of assets is spread across the economy

wealth inequality

when wealth is unevenly distributed across the economy

natural (non-accelerating inflation) rate of unemployment

the unemployment rate when the labour market is at equilibrium, when there is no demand-deficient unemployment and unemployment is only caused by supply side factors

Phillips Curve

shows the trade-off between the level of unemployment and the inflation rate
