Which type of economic policies aim to decrease unemployment by weakening union influence, implementing tax reductions, lowering unemployment benefits, and providing investment incentives?

Explanation

The described measures — diminishing union power, cutting taxes, reducing unemployment benefits, and offering subsidies for investment — are characteristic of supply-side policies. These strategies focus on improving the productive capacity of the economy by incentivizing production and labor market flexibility, rather than stimulating demand directly as Keynesian policies do.
