Definition of 'Laffer Curve'
Invented by Arthur Laffer, this curve shows the relationship between tax rates and tax revenue collected by governments. The chart below shows the Laffer Curve:
The curve suggests that, as taxes increase from low levels, tax revenue collected by the government also increases. It also shows that tax rates increasing after a certain point (T*) would cause people not to work as hard or not at all, thereby reducing tax revenue. Eventually, if tax rates reached 100% (the far right of the curve), then all people would choose not to work because everything they earned would go to the government.
