Laffer Curve
Taxation Advancedलैफर वक्र
Definition
The Laffer Curve illustrates the relationship between tax rates and total tax revenue. It shows that beyond an optimal point, increasing tax rates actually reduces revenue because it discourages economic activity, encourages evasion, and drives capital away. India's corporate tax cut in 2019 (from 30% to 22%) was partly based on this theory.
