Primes¶
- Demand
- The local elasticity is \(\varepsilon = \frac{dQ}{dP}\cdot\frac{P}{Q} = -2 \cdot \frac{P}{Q}\), which is not constant: at \(P = 10\) it is \(-2 \cdot \frac{10}{80} = -0.25\) (inelastic — a price change mostly transfers surplus), while at \(P = 40\) it is \(-2 \cdot \frac{40}{20} = -4\) (elastic — price is the dominant lever).
This sourceStandard text deriving point elasticity along a linear demand curve (elastic versus inelastic regions) and consumer surplus as the area under the demand curve above price.

- Diminishing Incremental Gains
- … efforts, and optimization initiatives should each have clear criteria for resource reallocation once marginal returns fall below organizational alternatives, formalizing what Varian (2014) presents as the textbook equimarginal principle: at an optimum the marginal benefit per dollar must be equal across all uses.
This sourceDevelops the equimarginal principle (at an interior optimum the ratio of marginal benefit to price is equalized across uses) as the formal stopping rule for concave-objective allocation.

- Distortion
- In economics, a tax, subsidy, monopoly, or externality produces an equilibrium that deviates systematically from the no-friction reference allocation, and the deviation has characterizable shape — a deadweight-loss triangle, a supply-curve shift — keyed to the intervention.
This sourceStandard derivation of deadweight loss as the welfare distortion from taxes, subsidies, monopoly, and externalities relative to the competitive equilibrium. (Print textbook, ISBN 978-0-393-12396-8.)

- Elasticity
- Compute price elasticity of demand for a good on the schedule \(Q = 100 - 2P\).
This sourceStandard derivation of price elasticity of demand as the unit-free ratio (dQ/Q)/(dP/P), its regime classification (elastic/inelastic), its variation along a linear demand curve, and its link to revenue.

Domain-specific¶
- Slutsky Decomposition
- Slutsky decomposes a movement generated by a price change. Not Giffen behavior. Giffen is the special case in which an inferior good's income effect opposes and outweighs its own-price substitution effect
This sourceVarian's Slutsky Equation chapter, the standard textbook location for the Giffen case as an inferior good whose income effect opposes and outweighs its substitution effect.

Mechanisms¶
- Ad Spend Cap
- It operationalizes the economist's stopping point where marginal cost meets marginal revenue: keep buying only while the next unit still returns more than it costs.
This sourceDerives profit maximization at the point where marginal revenue equals marginal cost, with expansion warranted while marginal revenue exceeds marginal cost.

Verification¶
Does it exist? Confirmed. This work's ISBN resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 6 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
