The
Rahn curve, shows the effect of government spending (as a
percentage of GDP) on economic growth.1,2
As
expected, the Rahn curve has a behaviour similar to what we
described for the STING
curve.

Scholarly
research indicates that most industrialized nations are on the
downward sloping portion of the Rahn Curve.
In
other words, policymakers could enhance economic performance,
government revenue and crucial social programs by
reducing the size and scope of government.
