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.
Allow about 165 minutes for reading, learning and immediate practice. Multi-day exercises run alongside later lessons.

The lesson
The postscript changes the question from applause to prediction
The postscript returns to incentives, delayed effects and administration. It proposes treating a policy as an empirical wager: what must be true for the promised outcome to occur? This is a useful discipline even when the reader disputes the author’s policy preferences. Translate the promise into outcomes, a time horizon, affected groups and a comparison. A prediction that cannot fail under any imaginable observation is not doing the work the postscript asks of it.
Its example tests concern housing units and quality, labour-market entry and training, revenue after behavioural response, and harm reduced relative to regulatory cost. Each needs operational detail. A rise in housing units may coexist with displacement or lower quality. Increased entry may involve firms that quickly fail. Revenue may vary with a wider economic change unrelated to the policy. Specify more than one relevant outcome and avoid declaring success from a convenient single measure. The source calls its recurring observations descriptive, but that description does not exempt broad claims from evidence or eliminate disagreement about values.
Complete the institutional and welfare account
The final glossary cluster includes regulation, economic rent, rent control, risk pricing, scarcity, social capital, spillovers, subsidies, supply, tax bases and wedges, throughput, transaction costs and valuation. These terms connect private decisions with institutions and people outside a transaction. Regulation can protect safety, prevent fraud or address an information problem; it can also impose excessive costs or protect incumbents. The glossary itself asks whether a clear harm is addressed proportionately. Apply that criterion rather than beginning with an abstract verdict that every rule is either good or bad.
Spillover benefits and costs require a defined channel and affected group. A subsidy may change demand, production or risk depending on its design; distinguish a buyer grant from support that relaxes a production constraint. Social capital concerns norms, networks and trust, but a close network can also exclude outsiders. Time as tax and throughput focus attention on delays and capacity. Not every delay is waste: some checks prevent a specific harm. Compare that benefit with its cost and examine a faster feasible design. The strongest account keeps both the institutional purpose and the opportunity cost visible.
End with a recommendation that can be revised
Use the glossary’s better-test idea to write a review plan. State the baseline, intervention, comparator, outcomes, data needs, time horizon and decision rules. Distinguish measurement from causal attribution: observing a change after a policy is not enough to show the policy caused it. Ask what else changed and what comparison would help separate explanations. Include uncertainty about response size, administration and who gains or loses. Where values conflict, say how they were weighed instead of hiding that choice inside a technical term.
A strong capstone does not need to endorse the author’s conclusion. It needs to reconstruct relevant mechanisms, perform correct arithmetic, test alternatives and explain its limits. It should also identify implementation risks and a proportionate plan for revision if the expected benefits fail to appear. The manuscript’s index contains only a heading, so no missing index entries have been invented; use the course’s chapter and term navigation instead. The postscript’s final habit is to keep tracing the bill. In this course that includes tracing benefits, testing assumptions and recognising when the available evidence supports a narrower conclusion than the rhetoric suggests.
Worked example · invented for this course
Original course example: a permit reform with a testable promise
A fictional town proposes replacing a twelve-week workshop permit process with a four-week process while retaining specified safety checks. It predicts more new providers and unchanged safety outcomes.
Specify which steps change and which remain, including staffing and appeal arrangements.
Measure baseline waiting times, applicant costs, entry, survival, service quality and relevant safety incidents.
Choose a feasible comparator or phased introduction that helps distinguish the reform from a wider demand increase.
Track outcomes over a period long enough for entry and possible harms to appear, with subgroup reporting.
State revision criteria: unexpected safety deterioration, unequal access or failure to reduce actual waiting time should trigger investigation and redesign.
What follows: The reform is an examinable proposal with possible benefits and risks. A shorter announced deadline alone does not establish success.
