Synthesize the book’s Hazlitt, Stigler, Moral, and Boring Rules into a practical method for analysing consequences, entry, conduct, and institutions. Build a policy judgment that is explicit about counterfactuals, values, uncertainty, implementation, and revision.
Allow about 75 minutes for reading, learning and immediate practice. Multi-day exercises run alongside later lessons.
Learning objectives
Apply the chapter’s Hazlitt and Stigler rules as analytical questions.
Construct a counterfactual ledger of visible and less visible effects.
Evaluate entry barriers without treating all regulation as capture.

The lesson
From the broken window to the excluded entrant
Chapter 20 returns to the broken-window story: repair work is visible, while the alternative use of the owner’s resources is unseen. It then introduces the “wall” of licensing, compliance, and subsidies that can protect existing activity while blocking people outside. The source’s key move is to ask about a counterfactual, not to declare every visible benefit false. Repair can be necessary after damage, yet that does not make the damage a source of net wealth. Similarly, a rule may produce an observable benefit while imposing an opportunity cost. The task is to compare feasible alternatives and account for resources, risk, distribution, and time. Unseen possibilities need disciplined estimates; an imagined business that never formed is not automatically evidence of a loss of any chosen size.
The Hazlitt Rule widens the ledger
The book’s first named rule asks what happens after the immediate intervention. It connects money creation with purchasing power, technology restrictions with productivity, and capital taxation with future investment. These examples state the author’s proposed mechanisms and should not be repeated as unconditional forecasts. Scale, timing, institutional conditions, and policy design affect outcomes. The source explicitly says the rule is not against all government action; it is against action that ignores consequences. Apply the same discipline to inaction and deregulation. A missing safety rule may impose less visible harm; a public intervention may generate future benefits. A complete ledger identifies first effects, later responses, affected groups, opportunity costs, and uncertainty on all sides. The purpose is more complete comparison, not a technique for finding only the delayed costs of policies one already dislikes.
The Stigler Rule asks about the ladder
The second rule distinguishes protecting established firms from preserving the ability of outsiders to compete. The chapter’s examples are occupational entry, bank rescue, and housing restrictions. An entry test asks how money, time, qualifications, compliance, and connections determine who can participate. It also asks which requirements genuinely protect people from harm. The source’s statements that Stigler proved regulation is usually demanded by industry and defeated public-interest explanations are sweeping interpretations, not findings independently established by this course. Regulatory capture is a useful hypothesis alongside other motives and effects. A policy can benefit consumers and incumbents at once. Evaluate whether a less restrictive, feasible design achieves the legitimate purpose with wider access. Do not grade a learner by how many rules they remove; grade the evidence linking a requirement to protection or exclusion.
Synthesis requires resisting stronger claims than the evidence
The opening summary says rent control shrinks supply, wealth taxation bankrupts pensions, and tariffs tax families. These compact lines recall earlier arguments but compress conditional mechanisms into categorical results. A rigorous closing lesson restores the conditions: which market, which design, what response, compared with what alternative, and over what horizon? The wall metaphor similarly highlights excluded workers while leaving the regulation’s actual benefits to be measured. Use a causal diagram to make intermediate steps visible, then identify the weakest empirical link. A strong answer can accept the author’s diagnostic discipline while rejecting an unsupported magnitude or inevitability. The source’s notes and primary examples repeat the same lessons; they are reading evidence about the author’s argument, not independent verification of its strongest wording. Your analysis should show both what the chapter contributes and what still needs investigation.
Worked example · invented for this course
A licence that protects one group and excludes another
In an invented city, a delivery licence requires an expensive office lease. Officials say it improves accountability, while a safety audit finds that vehicle checks and complaint records address the actual hazards.
Identify the visible objective and the cost to entrants who could operate safely without an office.
Construct the counterfactual: targeted checks and a reliable contact requirement instead of the lease.
Compare consumer protection, enforcement costs, entry, and worker transition effects.
State which outcome would justify keeping or revising the lease condition rather than assuming any burden is illegitimate.
What follows: The Hazlitt rule widens the ledger; the Stigler rule examines entry. Together they support a testable redesign, not automatic removal of all licensing.
Train the skill
Practice and evidence
1. Create a two-sided unseen ledger
Choose a fictional policy that restricts a new delivery technology for safety. Compare the restriction, a targeted safeguard, and no new rule.
Deliverable: A three-option ledger with short- and long-run effects for four groups.
Include consumers, workers, entrants, and people exposed to accidents.
Record opportunity costs and possible delayed benefits as well as costs.
Mark each effect as observed, assumed, or needing evidence.

Total available: 6 points
Symmetry 2 points
Applies second-effects reasoning to intervention and nonintervention.
Counterfactual 2 points
Compares feasible options and does not treat imagined losses as measured facts.

2. Test the wall metaphor
Audit the invented office-lease requirement for delivery licences.
Deliverable: A 400-word proportionality memo and three outcome indicators.
Describe the public objective in its strongest form.
Compare the lease with targeted alternatives.
Specify safety, complaints, and entry measures that could reverse your preferred decision.
Review criteria
Total available: 6 points
Fair reconstruction 2 points
Represents the legitimate objective rather than assuming bad faith.
Mechanism 2 points
Shows exactly how the lease changes entry and whether it contributes to protection.
Evaluation 2 points
Uses outcome-based review rather than ideological agreement.
