Issues#

Critical#

None found.

High severity#

  • [qe-code-003] — Duplicate !pip install --upgrade quantecon cells: at top (line 33) and again at line 82. Pip install should appear once at the top of the lecture.

  • [qe-ref-001] — Twelve narrative-author citations using parenthetical {cite} rather than {cite:t}. Examples: “Calvo ” (38, 244, 249, 1424), “Cagan ” (63, 107), “Chang ” (75, 153, 244, 249), “Sargent and Wallace’s ” (107).

Medium severity#

  • [qe-math-004] — \vec \mu, \vec \theta, \vec v used extensively (lines 150, 207, 209, 265, 267, 304, 337, 338, 341, 346, 715, 756). Count: 23 occurrences.

  • [qe-fig-003] — Embedded matplotlib titles: ax.set_title(fr'$\beta$={clq.β}, $c$={clq.c}') (line 1263), fig.suptitle(...) (line 1463).

  • [qe-link-002] — Four raw markdown links to python-intro.quantecon.org (lines 67, 193, 288, 765). Should be {doc} form.

  • [qe-fig-001] — figsize= set 5 times.

Low severity#

  • [qe-writing-001] — A few multi-sentence paragraphs (lines 38-39, 211-218).

  • [qe-writing-005] — Double-backtick quotes (line 227: ``bliss level``).

Strengths#

  • Lecture title in correct Title Case.

  • All H2 headings sentence case.

  • Matrices use bmatrix consistently (9 matrix blocks).

  • Definitions bolded (“time inconsistency”, “Definition”, “square summable”, “Insight”, “Ramsey plan”).

  • Equation labels and {eq} references used cleanly.

  • “IID”/Greek-letter conventions consistent; Unicode Greek (β, μ, σ) in code.

  • No transpose, no \tag, no align-inside-$$ issues.
