Score breakdown#

Category

Score

One-line note

Writing

4/10

H1 “Multiple goods” sentence case for what should be lecture title; structure broken (lecture starts with H2); many Title Case H2 sections.

Math

5/10

Mixed transpose: both \top and ^T used (M2 inconsistent); equations generally clean otherwise.

Code

N/A

no executable {code-cell} blocks (only inline python fenced code as illustration)

Issues#

Critical#

None found.

High severity#

  • W2 — H1 is # Multiple goods (line 145), buried 145 lines into the file, lowercase ‘goods’ (should be Title Case “Multiple Goods”); file actually begins with H2 ## Elements of Supply and Demand (line 3), so no proper lecture title at top.

  • W3 — Many H2 sections use Title Case. Examples: “## Demand Curve Implied by Constrained Utility Maximization” (line 216), “## Endowment Economy, II” (317), “## Digression: Marshallian and Hicksian Demand Curves” (284), “## Dynamics and Risk as Special Cases of Pure Exchange Economy” (375), “## Supply Curve of a Competitive Firm” (511), “## Digression: A Supplier who is a monopolist” (602). Count: 6+ headings.

Medium severity#

  • M2 — Mixed transpose: ^\top used in most places (line 160 onwards) but \Pi^T \Pi used in places (lines 188, 191). Count: 2-3 mixed instances.

  • W1 — Several multi-sentence paragraphs at top.

  • W7 — Typos: “compeitive” (line 33), “simulataneous” (line 137), “It we solve” (line 121), “we’ll can” (line 114).

Low severity#

  • W7 — Mixed H4 capitalization: “#### Example: Two-person economy without production” (877), “#### A dynamic economy” (970).

  • [qe-fig-001] — figsize= shown in inline code samples (lines 1129, 1344) — would carry over if these became {code-cell} blocks.

Strengths#

  • \top used for transpose in most places (M2 mostly OK).

  • Bold for definitions (consumer surplus, producer surplus, etc.).

  • Equation labels and {eq} references.
