Answer:
taxes and government spending
Explanation:
Under national income reporting, the purchase of commodities for existing use by policymakers is known as government spending cost to specifically meet the individual or grouped requirements of the people.
On the other hand, Taxes are unintended charges collected from companies or individuals being imposed by a government body — whether municipal, state or national — to fund the operations of the state.
Hence government authorities can use these two tools for shifting resources from private to public goods. They can increase their taxes on private goods consumption or can decrease their spending to support private goods industries.
