Apply the six-part test without assuming the verdict
Learn the book’s basic policy test and practice separating visible gains from later adjustment. The chapter introduces a value-laden argument for open opportunity; the course makes its mechanisms, assumptions, and evidence testable.
Allow about 100 minutes for reading, learning and immediate practice. Multi-day exercises run alongside later lessons.

The lesson
Demand support and supply conditions
The four compact examples turn the opening concepts into a repeatable procedure: identify the claim, expose a hidden assumption, predict behavioral response, trace later effects, locate incidence, and test a better design. In the homebuyer example the crucial assumption is supply responsiveness. A grant can increase bids; if new homes cannot be supplied, sellers may capture much of the benefit. If supply expands, part of the response may instead be additional housing. Timing, eligibility, credit conditions, and anticipation also matter. The course therefore asks for a conditional conclusion rather than the slogan that all grants inflate prices. Compare a grant with feasible supply reform, and compare both with doing nothing. The source's proposal to reduce zoning and permitting constraints deserves the same scrutiny: identify actual bottlenecks, construction lags, infrastructure needs, and who can benefit during the transition.
Inflation and wealth: identify the missing mechanism
The inflation example challenges an explanation based on an unexplained, economy-wide increase in greed. A stable motive cannot by itself explain a changing outcome; an analyst must identify what changed in demand, supply, monetary conditions, competition, or pricing opportunities. The book strongly favors monetary and supply explanations. That stance should not be taught as proving that margins or market power never matter. Distinguish a relative-price increase, a one-time level change, and continuing broad inflation, and ask what evidence separates explanations. The wealth-tax example makes a different category correction: an asset valuation is not cash available for payment. Owners may sell, borrow, use income, or restructure. These responses have distinct costs and distributional implications. The chapter opens a forced-selling argument but does not quantify its market-wide magnitude. Do not assume every liability forces liquidation, every sale destroys productive capacity, or every tax design has the same consequences.
Rent control, entry, and the book’s normative goal
The rent-control example contrasts incumbent tenants with excluded seekers and connects price limits to conversion, maintenance, investment, and mobility. Preserve both parts: protection can be real for existing tenants, and losses can emerge elsewhere. Evidence from a particular jurisdiction should not be silently generalized to every form of rent stabilization. Exemptions, vacancy rules, enforcement, new construction, and alternative tenant protections may change the result. The final sections state the author's moral priority: protect wealth creation while keeping entry and competition open. They distinguish inequality from immiseration and portray closed pathways as a central wrong. This is a normative framework rather than a neutral definition of all social objectives. A learner may also value security, bargaining fairness, or relative equality. Strong analysis makes those values explicit and tests whether the proposed means achieve them instead of grading agreement with the author.
Use notes as leads, then state a bounded conclusion
Chapter notes and linked footnotes supply references for rationing, housing subsidies, rent control, tax incidence, inflation, and wealth taxes. They are part of the required reading, but their presence is not independent verification. The housing-subsidy citation names a paper about second-home investment restrictions; the claimed connection to Help to Buy needs checking against the actual research. Broad summaries of the IMF, OECD, and tax-incidence studies also require examination of scope, methods, and dates before reuse as settled evidence. In this course, label these as claims reported by the book. A complete policy memo can still be written responsibly: distinguish theoretical channels from measured estimates, state what the source supplies, identify missing evidence, and give conditions under which your recommendation would change. The lesson line urges attention to consequences rather than intentions. Its best analytical use is a discipline of symmetric scrutiny: evaluate the proposed reform, the author's preferred alternative, and the status quo with the same ledger.
Worked example · invented for this course
A tool-library voucher
An invented town proposes a 50-unit voucher for renting construction tools. Only one shop operates, rental stock is fixed for six months, and a second supplier could enter after a permit change.
State the goal as usable tool-hours for low-income residents, rather than voucher redemption alone.
Trace two possible responses: higher rental charges with fixed stock, and additional inventory when supply becomes responsive. Neither response has a stipulated size.
Include nonrecipients, current users, the shop, taxpayers, and a potential entrant. Separate transfers from real resource costs.
Compare vouchers alone, permit reform alone, and a time-limited combined design. Measure prices, stock, waiting, and access for intended beneficiaries.
What follows: The chapter’s method flags capitalization risk but does not establish that the voucher is worthless. A recommendation depends on capacity, targeting, and feasible alternatives.
