#1069 - [two_auctions] Add exercises and further reading

Files Updated

• ✏️ lectures/two_auctions.md
• ✏️ .translate/state/two_auctions.md.yml
• ✏️ lectures/_static/quant-econ.bib

⚠️ Target-Only Sections Removed

The following sections exist in the current translation but have no counterpart in the source document, so this sync removes them (the translation mirrors the source's structure). If the source deleted these sections, this removal is correct — merge as usual. If they are human-authored additions you want to keep, move them into a target-only file before merging (see adding content to a translated edition).

📝 Translation Quality

Criterion	Score
Accuracy	9/10
Fluency	9/10
Terminology	9/10
Formatting	8/10
Overall	8.9/10

Summary: The translation of the modified sections is accurate, fluent, and terminologically consistent with the glossary, faithfully preserving all mathematical content, code blocks, and MyST cross-references. Only minor stylistic issues were found (e.g., slightly awkward phrasing in a couple of sentences, and unexplained font-setup additions in a code cell), with no blocking or major errors detected in the newly added Exercises and Further reading sections or other modified sections. Highly accurate rendering of dense mathematical derivations and equations across all modified sections, with LaTeX intact and correctly formatted. New Exercises and Further reading sections are translated fluently and consistently, preserving citation keys, cross-references, and code blocks unchanged as required. Consistent terminology usage for auction-theory terms (贝叶斯纳什均衡, 收益等价定理, 密封投标拍卖, etc.) throughout the changed sections. Proper full-width punctuation and correct spacing around inline MyST directives and citations observed in the changed sections.

Suggestions:

• [minor · formatting] lectures/two_auctions.md — ## Python code (code cell imports): The translated code cell adds extra lines not in the English source (font configuration via matplotlib and FONTPATH), which is an unexplained addition to a code block that was otherwise meant to be a faithful translation of surrounding prose/text. → If this font setup is a project-wide convention for CJK rendering, consider noting it consistently; otherwise keep code cells identical to source unless intentionally modified for rendering Chinese text.
• [minor · terminology] lectures/two_auctions.md — ## First-price sealed-bid auction (FPSB) intro paragraph: The source says 'a single good is allocated to one person within a set of people,' which the translation renders as '我们将讨论如何将单个商品分配给一组人中的一个人' — this shifts from a declarative statement to 'we will discuss how,' slightly altering register/meaning versus adjacent sentence structure (though not a major distortion). → 在本讲座中，单个商品被分配给一组人中的一个人。
• [minor · fluency] lectures/two_auctions.md — ## Second price sealed bid auction: The phrase '在第二价格密封拍卖中，对竞价者$i$来说，出价$v_i$是最优选择' is a bit awkward compared to more direct phrasing used elsewhere (e.g., '投标者i的最优出价是...'). → 在第二价格密封拍卖中，投标者$i$的最优选择是出价$v_i$。
• [nit · formatting] lectures/two_auctions.md — table under Revenue equivalence theorem summary: Table column header '密封投标拍卖' merges 'Auction: Sealed-Bid' loosely; acceptable but could be slightly clearer as '拍卖：密封投标' to mirror source structure more closely, though this is a stylistic nit only. → 拍卖：密封投标
