What is the difference between short-run and long-run economic growth?

Short-run growth is simply an increase in a country's 'gross domestic product' or 'GDP', whereas long-run growth is an increase in the country's productive capacity. When thinking in terms of an AD-AS diagram, short run growth may be shown by an outward shift in aggregate demand which leads to an increase a long the "GDP" axis. Long run growth may be shown by an outward shift in AS, as this shows an increase in the country's productive capacity.
