A

stuck in the deflationary gap bc hard for the economy to recover

46
Q

2nd section in k [4]

A
  • real gdp increases with price level
  • decreasing amount of spare capacity

47
Q

section 3 in k [4]

A
  • real GDP is maximised
  • no spare capacity

Q

stakeholders to inflation

A

workers
gain: firms give them pay rise because inflation increases the cost of living
loss: sticky wages, contract forbids a pay rise (fixed income earners) percentage change of pay rise is lower than percentage of inflation
savers
gain: increase in interest rates, more money received from saving interest % inflation %
loss: the purchasing power of their savings would decrease due to inflation
lenders
gain: higher interest rates, they are paying less to the bank Loss: more people would rather save as there is a price increase
loss: value of money decrease if borrower return the same amount of money
borrowers
employers (i.e. people who pay workersʼ salaries)
gain: no pay rise, value of money decrease, less real cost of production
loss: Costs of production increase because of inflation, and this includes the aforementioned increased wages for workers. They have to either cut workers, cut corners or reduce supply in order to compensate
