Measurements of economic performance Economic growth
Two meaning of the term economic growth: - Actual growth, increase in real incomes or GDP - Potential growth, increase in the productive capacity in a country Real values are adjusted to remove the effects of inflation.
Nominal values are current incomes that are not adjusted 
For GDP to have any significance in terms of standards of living; figures must be given per head (or per capita).
E.g. If incomes increase by 10% but population increases by 20% people are worse off per head. 
Important distinction, look at value not volume when measuring economic growth.
E.g. Germany biggest exporter in the world in terms of value whereas china exports a lot more in terms of volume. How is GDP measured? 

GDP is the sum of all goods and services produced in a country in a year. It is also the sum of all incomes earner in a year and the sum of all expenditure in one country in a year. 

Increase in GDP is a sign that a country is experiencing increasing incomes, outputs and spending. (Not always right,
e.g. if you earn more you may work long hours, be under pressure, depression etc.) 

Problems of comparison:
- Subsistence, barter and the black economy. Farmers consume their own output, goods traded without price system; goods paid for and not declared (to dodge tax)
Currency values. Knowing whether to use official value of currency or purchasing power of a currency Income distribution.
-Size of public sector. If much of the spending in the economy is by government it might or might not improve welfare for the population. 
Consumer and capital spending. Spending on investment goods may lead to increased standard of living in future at the price of standard of living today and GDP does not take future into account. Better if figures are broken down to look at the investment elements.
-Quality issues. E.g. spending on schools may be high but how do we

    Economics growth is, it the short run an increase in real GDP and in the long run an increase in the productive capacity of an economy (the maximum output that the economy can produce). GDP stands for Gross Domestic Product which is the country’s production of goods and services valued at market price in a given time period. Real GDP is when these figures are corrected for inflation using a base year (The UK uses 2003 as its base year). It can be measured in three different ways; the output measure is the value of the goods and services produced by all sectors of the economy; agriculture, manufacturing, energy, construction, the service sector and government. The expenditure measure is the value of the goods and services purchased by households and by government, investment in machinery and buildings. It also includes the value of exports minus imports and finally the income method is the value of the income generated mostly in terms of profits and wages. Economic growth is often a result of low unemployment, which has an effect on the components of aggregate demand in that consumption will rise as when more people have a job, more people have more disposable income, savings and investment rise and with this productivity rises too.
