Final answer:
The proposed policy would result in a less progressive tax system and does not satisfy all principles of sound tax policy. The implications from the behavioral tax perspective are varied.
Step-by-step explanation:
Progressivity:
The proposed policy would result in a less progressive tax system. By decreasing the number of tax brackets from 7 to 3 and reducing the top marginal income tax rate from 37% to 15%, individuals with higher incomes would see a significant decrease in their tax liability. This means that those with lower incomes would be relatively burdened more compared to higher income earners.
Principles of Sound Tax Policy:
The proposed policy does not satisfy all five principles of sound tax policy. The five principles are efficiency, equity, simplicity, transparency, and adequacy. While the policy may improve simplicity by reducing the number of tax brackets, it is not equitable as it reduces the progressivity of the tax system. Efficiency, transparency, and adequacy are also not fully met as the policy does not address the overall effectiveness and fairness of the tax system.
Behavioral Tax Perspective:
The implications of this policy from the behavioral tax perspective could vary. Some argue that reducing tax rates can incentivize individuals to work more and increase economic growth. However, others believe that decreasing progressivity could lead to income inequality and reduce social and economic mobility.
