➤ How do externalities relate to public goods and market failure?
Externalities occur when a transaction affects third parties who are not part of the market exchange. Positive externalities, like herd immunity, often accompany public goods and create benefits that producers cannot capture. This gap causes private underinvestment. The market fails to reflect full social benefits, so socially desirable public goods remain undersupplied without intervention.

➤ What types of Medicaid expenses does the federal share cover?
Federal matching funds cover state Medicaid expenditures approved under the state plan. This includes mandatory benefits (for example, inpatient and outpatient services), many optional services, and allowable administrative costs. States must meet federal requirements to claim these funds, and some programs or expansions qualify for higher, enhanced matching rates.

➤ How do checks and balances relate to separation of powers?
Checks and balances are practical tools that enforce separation of powers. Each branch holds authorities to limit others, for example vetoes, judicial review, budget control, and confirmation processes. Those reciprocal powers force negotiation, prevent unilateral actions, and maintain constitutional stability by ensuring no branch dominates government decision-making.
