Inflation Flashcards
Define demand pull inflation
When aggregate demand is growing unsustainably, there is pressure on resources so producers increase their prices to earn more profit. It usually occurs when resources are fully employed
Define price-wage spiral
When price level increases so the cost of living increases so workers demand higher wages, shifting SRAS to left which leads to higher prices even further
Pros and cons of inflation
Pros
- reduce real value of debt so improves inequality
- protection from deflationary spiral
Cons
- inflation wont affect nominal value of savings but real wage will decrease, worsening inequality
- price-wage spiral can lead to hyperinflation
Hyperinflation definition
when the rate of inflation rises above 50%
Define deflation
A sustained decrease in the general
price level
Causes of deflation
reduction in aggregate demand
increase in aggregate supply
What does the inflation rate tell us?
The percentage change in the general price level
Multiplier ratio formula
Change in real GDP / Initial Injection
Define disinflation
A decrease in the rate of inflation as the general price level is increasing but at a slower rate than before
Define nominal income
Define real income
Nominal income - how much you earn
Real income - nominal income adjusted for the effects of inflation - how much your income is really worth
What are the main triggers for demand-pull inflation?
- Lower interest rates - makes saving less attractive so borrowing becomes more attractive therefore AD increases
- Fiscal stimulus in the form of lower taxes and an increase in government spending means consumers have more disposable income so consumption increases which increases AD
- Depreciation in the exchange rate means imports become more expensive while exports become cheaper which causes AD to rise
- High growth in UK export markets means exports increases and AD increases
Define cost-push inflation
When the cost of production and raw materials increases, leading to higher prices for goods and services
What is the macroeconomic objective for inflation in the UK?
The inflation rate to be at 2% + or - 1% in order to maintain price stability
Define CPI and how it measures inflation
Consumer price index measures purchasing power of households using the family expenditure survey. From this a basket of goods is created and weighted according to how much income is spent on the goods. The CPI measures the average price change of these goods and is updated annually to account for changes in spending patterns
Limitations to using CPI
- The basket of goods is only representative of the average household, so it is not
accurate for all households - Different demographics have different spending patterns
- CPI does not include mortgage repayments, despite most income going towards that
- Increase in the price level is often accompanied by other improvements such as improvement in quality of goods and services which is ignored by CPI
- Despite being updated annually, CPI is slow to respond to new goods and services and it is hard to make historical comparisons, since technology was of a vastly different quality
