What is Economic Growth?

 

Economic growth is an increase in the productive capacity of an economy. It is measured by comparing the GDP (total value of goods and services produced in an economy) in one year to GDP in the next. In the short run that means increasing aggregate demand, but in the long run growth can only continue if the capacity of the economy to produce goods and services is increased. This is done with supply side policies that shift the long run aggregate supply curve right.
