MACRO L5 - Inflation Flashcards
define inflation
the annual percentage increase in prices of goods/services over time
what are the two types of inflation
- demand pull
- cost push
what is demand pull inflation
- inflation caused by percentage rises in aggregate demand
how do firms respond to rising demand
- they raise prices and increase output
what is cost push inflation
inflation caused by persistent rises in costs of production
how do firms respond to rising costs
- they raise prices and decrease output
what is a demand shock
single increase in demand (e.g. increase in government spending) that leads to a short-run increase in inflation
what is a supply shock
single increase in costs (e.g. government increases tax on petrol) that leads to a short-run increase in fuel prices
what can uncertainty over inflation lead to for firms
- firms lower investments, which reduces economic growth
define hyperinflation
a very high and typically accelerating inflation. It quickly erodes the real value of the local currency, as the prices of all goods increase.
what does the Phillips curve show
- suggests an inverse relationship between unemployment and inflation
- lower unemployment tends to be associated with higher inflation
define stagflation
combination of economic stagnation (low GDP growth and high
unemployment) and high inflation
