Q

What are index numbers?

A

Economists use index numbers to analyse time series data. A base year is selected and assigned the value 100. Data for subsequent years is represented by a number that shows how the variable has changed relative to the base.

18
Q

How can you calculate an index number?

A

Index number = (current figure / figure in base year) x 100

19
Q

How can you calculate the real value of nominal data?

A

Real value = (index of comparison / index of current) x nominal value

20
Q

What are some limitations of using GDP per capita to compare living standards over time?

A
  • price have increased over time
  • statistics are inaccurate
  • changes in population over time
  • quality of goods and services may improve over time but they may fall in price
  • proportion of national income devoted to defence should be considered
  • national income spent on investment affects living standards
  • externalities aren’t taken into account eg. pollution
  • increased national income may not mean individuals have increased incomes
21
Q

What are the limitations of using GDP per capita to compare living standards between countries?

A
  • they may use different accounting conventions to calculate NI
  • the quality of data varies
  • the size of the unrecorded economy differs between countries
  • quality of goods and services differs
  • countries spend different proportions of GDP on defence and other expenditures
  • externalities aren’t considered
  • income distributions differ between economies
  • geography distorts comparisons eg. size/temperature
  • market exchange rates don’t reflect purchasing power, may distort comparisons
  • different countries have different purchasing power parity rates that they can survive at
  • informal/black market activity not recorded
  • percentage change is misleading
  • population rates distort the data
  • spending on investment goods will raise future living standards at the expense of current living standards
22
Q

What are purchasing power parities?

A

GDP is converted into a common currency at a PPP rate - a rate of exchange that allows a given amount of money in one country to buy the same amount of goods in another country after exchanging one currency into the other.

23
Q

What is the Easterlin Paradox?

A

Happiness and income are positively related at low levels of income. Higher levels of income are not associated with increases in happiness.

24
Q

Why are income and happiness weakly correlated?

A

Happiness is caused by a variety of different factors.

25
Q

Why do those with above average incomes tend to have higher levels of happiness?

A

This may be because people see income as a symbol of social status and this make people happier. Also, higher incomes are correlated with other factors associated with happiness eg. better health, less likely to be unemployed.

26
Q

What is short-run economic growth?

A

A change in Y/Q or AD, closes the output gap. Shown by an increase in AD on a diagram.

27
Q

What is short-run economic growth caused by?

A
  • increase in AD
  • export-led growth = positive net exports
  • utilisation of spare capacity = more efficient use of existing FOPs
28
Q

What is long-run economic growth?

A

The underlying rate of growth the economy can sustain without generating inflationary pressure. The speed at which the economy could grow, an increase in the productive capability of the economy.

29
Q

What is long-run economic growth caused by?

A
  • an increase in the quality/quantity of land, labour and capital
  • technological improvements increase the marginal efficiency of capital
30
Q

What is the quantity of labour determined by?

A

Size of the labour force:
- participation rate = the economically active labour force
- size of population - net migration and demographics

31
Q

What is the quality of labour determined by?

A
  • training and education
  • healthy workers are more productive
32
Q

How is long-run economic growth illustrated on a diagram?

A

Increase in aggregate supply.

33
Q

How is short-run economic growth illustrated on the PPF?

A

Actual growth = a movement from inside the PPF, where FOPs are underemployed, towards the boundary

34
Q

How is long-run economic growth illustrated on the PPF?

A

Potential growth = an outwards shift from the boundary

35
Q

What are the characteristics of an economic boom?

A
  • positive output gap
  • economy operating at full capacity
  • low unemployment
  • high profits
  • increased business /consumer confidence
  • demand induced investment
  • firms increase stocks and production
  • positive multiplier
  • increased consumption
  • budget surplus
  • demand-pull inflation
  • high levels of borrowing from banks
36
Q

What are the characteristics of an economic recession?

A
  • negative output gap
  • economy operating below trend
  • spare capacity
  • increased unemployment
  • falling profits
  • decreased business and consumer confidence
  • investment falls
  • firms reduce stocks and production
  • negative multiplier
  • consumption falls
  • budget deficit
  • disinflation or deflation
  • low levels of borrowing from banks
37
Q

What is a positive/inflationary output gap?

A

Economy is growing faster than trend AD, increasing faster than capacity. Temporarily operates beyond capacity

38
Q

How is a positive output gap illustrated on a diagram?

A

Short run equilibrium (SRAS = AD) at a higher level than long run equilibrium.

39
Q

What is a negative/deflationary output gap?

A

Actual GDP is below trend GDP, the economy is growing below trend reducing inflationary pressure

40
Q

How is a negative output gap illustrated on a diagram?

A

The short run equilibrium (SRAS=AD) is below the long-run equilibrium

41
Q

What determines the trend growth rate of the economy?

A

The productive potential of an economy which is determined by the FOPs available to an economy. Affected by quality/quantity of FOPs, technological advances and efficiency

42
Q

Why do economies grow at different rates?

A

Natural resources - if they have resources such as gas and oil, they can export them to increase their economic growth rate
Participation rates - if a large number of the population are working age, they have an increased labour force causing economic growth. However some countries have an aging population, so growth is slowing.
Investment levels - capital stock needs to be increased to sustain economic growth, so high investment means the economic growth rate can be increased.
