The gross domestic product, GDP, can be measured in several different ways. The most common is to look at GDP at fixed prices. This calculation removes the effects of inflation and instead measures the quantity, the volume, of what is being produced. However, GDP at fixed prices does not take into account if we are being paid more or less for our export in relation to what we pay for our import.
If for example the prices of our export goods fall in relation to our import prices, we have to produce and export more goods in order to pay for the same amount of import goods. Therefore, a GDP measure that also includes changes in export- and import prices gives a better picture of a country's wealth compared to GDP at fixed prices. This measure is called real GDP.
Using real GDP, the growth rate in Sweden has been weaker than what the usual GDP measure suggests. Thus Swedish companies have received less money for their export. Furthermore, the trend is that the gap between GDP measured in fixed prices and real GDP is increasing.
