Trace the burden through incentives, time and rationing
Consolidate the glossary into a working analytical toolkit, then apply the postscript’s demand for testable mechanisms. Produce a policy comparison that handles resources, behaviour, administration, distribution and uncertainty together.

The lesson
Follow responses rather than labels
The middle glossary cluster connects incentives, incidence, pass-through and liquidity with investment and the ladder into opportunity. Incidence asks where a burden ultimately falls after responses; pass-through describes channels through prices, wages or returns. Naming a company, landlord or buyer in a rule does not finish the analysis. Nor should the analyst assume complete shifting in a preferred direction. The glossary itself notes that pass-through can be limited or substantial depending on market conditions. Specify alternatives, bargaining conditions, competition and time.
Marginal tax rates concern an additional unit of the relevant base, while an average rate concerns total liability relative to a stated total. Lock-in concerns an incentive to postpone a change because it triggers a cost. Moral hazard concerns changed risk-taking under protection; it is not simply an insult to recipients. Human capital concerns productive capacities, while signalling concerns what others infer. These distinctions help separate the formation of competence from the information used to identify it. They also prevent a policy discussion from treating a label as a full explanation of behaviour.
Scarcity does not disappear when payment changes form
The entries on zero monetary prices, queues, price caps, rationing and redistribution ask how scarce capacity is allocated. A service can charge nothing at the moment of use while still consuming staff time, facilities and other resources. Waiting, eligibility and triage may then matter. But the same fairness test must be applied to price allocation: ability to pay is not identical to need or benefit. The glossary explicitly acknowledges that different allocation methods favour different groups and that none is automatically morally pure.
A complete comparison therefore states the objective and the allocation rule. It asks about availability, quality, waiting, financial burden and distribution, rather than treating a low posted price as the whole outcome. A binding price cap and a cap above the relevant market price are not the same intervention. A queue caused by a temporary shock differs from one caused by a permanent capacity constraint. Income support, pooled risk or a subsidy may have defensible aims, and supply response remains relevant to evaluating their design. Count both benefits and burdens instead of assuming that identifying one mechanism resolves the choice.
Keep book-specific language and conditional claims visible
The glossary explicitly uses liquidity trap for a wealth-tax setting in which recurring cash obligations interact with illiquid assets. It says this is not its central-banking meaning. When using the phrase in this course, state that book-specific sense. The label does not remove the need to show the cash shortfall, payment timing, available options and consequences. Likewise, ladder and levelling express the author’s way of framing opportunity and outcomes. Explain those frames while recognising that a policy can affect entry, distribution and security at the same time.
Inflation, indexation, real wages, productivity and investment connect nominal amounts to what resources can actually buy or produce. A rise in nominal pay is not the same as a rise in purchasing power. A model linking investment to productivity is not an unconditional statement that every investment benefits every worker equally. The glossary often compresses these steps. Re-expand them in your answer: state the mechanism, the necessary conditions and a possible competing effect. This habit preserves the force of the source’s questions while keeping the analysis proportionate to what the evidence can support.
Worked example · invented for this course
Original course example: three ways to allocate twenty workshop places
A fictional training centre has twenty places and forty applicants. It considers a fee, a first-come queue or a needs-and-readiness process. No immediate expansion is possible.
State the objective: access to useful training, including applicants with limited resources.
Under a fee, examine ability to pay and whether financial support changes access. Do not assume willingness to pay perfectly measures benefit.
Under a queue, examine time flexibility and how applicants learn when registration opens.
Under needs-and-readiness selection, examine criteria, administrative effort, error and appeal.
Compare feasible expansion later and make the trade-offs explicit instead of describing any method as costless.
What follows: All three methods allocate scarce places and distribute burdens differently. The preferred design depends on the objective, evidence and constraints.
