Q

What are the main triggers for demand-pull inflation?

A
  • 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

Q

Define CPI and how it measures inflation

A

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

Q

Limitations to using CPI

A
  • 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
