Trace the chapter’s proposed repricing mechanisms through pensions, endowments, insurers, and households. Learn to distinguish exposure from demonstrated harm, a current price loss from future returns, and an institution’s asset movement from its ability to meet obligations.
Allow about 75 minutes for reading, learning and immediate practice. Multi-day exercises run alongside later lessons.

The lesson
Start with exposure, not the identity on the bill
Chapter 15 argues that a tax aimed at wealthy holders can affect others through shared capital markets. The distinction is between legal liability and economic incidence. A pension member might owe no asset tax while owning claims affected by market prices. The source lists pension funds, retirement plans, mutual funds, insurance portfolios, endowments, public funds, and bank balance sheets. Build an exposure map rather than assuming every household holds the same portfolio. Some exposure is indirect, through institutional funding or employment. Exposure alone does not quantify a loss or prove that a particular policy causes one. Identify the instrument, the holder, the relevant price or cash flow, and the path to a household consequence. The book’s “shared plumbing” metaphor is a prompt for that analysis, not a substitute for it.
Separate the four valuation channels
Section II describes four routes to lower equity prices. Lower expected distributable cash flows can reduce value. A higher required return can reduce the present value of unchanged expected cash flows. Reduced liquidity may increase trading costs and the return investors require. Forced sales may create temporary or persistent price pressure when buyers cannot absorb them at prevailing prices. These are conditional mechanisms. A tax on one owner’s wealth is not automatically a tax on the firm’s operating cash flow, and a tax-exempt holder may face different direct treatment from a taxable holder. Market composition, timing, financing choices, and expected future policy all matter. The lesson is to name the exact channel before calculating a price effect. Listing four channels does not justify adding four unmeasured losses or assuming each operates independently.
A lower price and a lower future return are not identical
The chapter sometimes moves between a fall in asset values and a reduction in future returns. Preserve the distinction. If expected cash flows remain unchanged but a higher required return lowers today’s price, existing holders experience a valuation loss while a new buyer pays less for the same expected stream. That is not the same as every future buyer earning a lower expected return. In an invented perpetual-flow model, annual cash of 5 with a required return of five percent is worth 100; with a required return of six percent it is worth about 83.33. Alternatively, reducing cash to 4 at five percent gives 80. Both lower prices, but they tell different stories. The source’s price-pressure examples motivate investigation; they do not establish that an annual tax necessarily institutionalises a market-wide fire sale.
Pension design determines who adjusts first
In a defined-contribution plan, a member’s account reflects contributions and investment outcomes, so a market decline changes the account balance directly. In a defined-benefit arrangement, the promise and the asset pool must be analysed together. A shortfall can lead to contributions, sponsor support, benefit changes where permitted, or a different investment strategy. The chapter highlights workers, employers, and taxpayers as possible bearers. Do not infer a funding gap solely from an asset-price change without inspecting liabilities, discounting, hedging, and the governing rules. Its OECD, Pew, investment-industry, and fire-sale references are attributed support, not independently checked current measurements here. A credible pension analysis states exposure, liabilities, horizon, and adjustment rules before predicting retirement consequences. It also separates a temporary mark-to-market change from a permanent impairment of the plan’s capacity to pay.
Worked example · invented for this course
Two retirement arrangements, one market shock
In an invented economy, an equity index falls 10%. Lina’s defined-contribution account holds 60% in that index; a municipal defined-benefit plan holds 40% and also has long-term liabilities.
With other assets unchanged, calculate Lina’s immediate account impact as a 6% decline.
Calculate the plan’s asset-only impact as a 4% decline, keeping liability changes unresolved.
Ask whether the price fall came from lower cash flows, changed required returns, or selling pressure.
Identify who would bear any confirmed funding adjustment under the plan’s rules.
What follows: The same market movement has different institutional consequences. The example does not attribute the shock to a real tax or establish the defined-benefit funding gap.
Train the skill
Practice and evidence
1. Draw the incidence network
Map a proposed tax on concentrated shareholdings to three indirect holders and one non-investor household channel.
Deliverable: A labelled network with four conditional paths and evidence requirements.
Identify the legally liable person.
Name the mechanism linking that person’s response to a market or firm outcome.
State what must be true for each household consequence to follow.
Review criteria
Total available: 6 points
Incidence 2 points
Keeps legal payment separate from price, employment, and institutional effects.
Mechanisms 2 points
Names a specific channel at every step rather than relying on a shared-market slogan.
Limits 2 points
Identifies exposure and offsetting effects needed to estimate net consequences.
2. Compare two present-value shocks
Use annual cash flow 5 and required return 5% as the perpetual baseline. Compare cash falling to 4 with the rate unchanged against the rate rising to 6% with cash unchanged.
Deliverable: Three values and a 300-word explanation for existing holders and new buyers.
Calculate baseline and both alternatives.
Explain the two mechanisms without treating prices and future returns as synonyms.
Identify two omitted real-world features.
