Government Failure, Inequality and Welfare
Judging intervention when information, incentives, administration, political constraints and distributional objectives can produce trade-offs or unintended outcomes.
How to study A-level Economics
Define the issue and affected agents, choose an appropriate model, build the causal chain with data, then evaluate assumptions, trade-offs and alternatives before judging.
Core concepts
Concept 1
Government failure occurs when intervention produces a less efficient or otherwise worse outcome against the relevant criteria.
Exam cue: Identify the government information or incentive problem and trace its consequence.
Concept 2
Income and wealth inequality differ, and measured distribution depends on units, time, transfers, taxes and data quality.
Exam cue: Use current distribution data with clear definitions and comparisons.
Concept 3
Efficiency, equity, freedom, security and sustainability can conflict, so policy evaluation requires explicit criteria.
Exam cue: Make the value judgement explicit when choosing between efficiency and equity outcomes.
Risk pitfalls and guardrails
Treating any policy cost as proof of government failure.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Confusing income with wealth.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Assuming equal outcomes and equal opportunities are the same objective.
Guardrail: Do not substitute a memorised diagram or generic advantage until you have identified the determinant, mechanism, affected agents and time horizon.
Memory anchors
Government Failure
Government failure occurs when intervention makes outcomes worse against the relevant social criteria.
Income

Wealth
Wealth is a stock of assets minus liabilities at a point in time.
Equity
Equity concerns fairness and depends on the criterion being applied.

Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
