Supply-side economics emphasizes economic growth achieved by tax and fiscal policy that creates incentives to produce goods and services. In particular, supply-side economics has focused primarily on lowering marginal tax rates with the purpose of increasing the after-tax rate of return from work and investment, which result in increases in supply.
The broader supply-side policy mix points to the importance of sound money; free trade; less regulation; low, flat-rate taxes; and spending restraint, as the keys to real economic growth. These ideas are grounded in a classical economic analysis that understands that people adjust their behavior when the incentives change. Accordingly, the lower the regulatory and trade barriers, and the lower and flatter the tax rate, the greater the incentive to produce.
