Summary: 此次改动涉及的新增与修改章节翻译质量很高，准确传达了原文的经济学与数学论证过程，术语使用规范且与术语表一致，公式与代码块格式完整无误。仅存在个别措辞可进一步打磨之处（如 'putty-clay' 的翻译方式），不影响整体理解和学术严谨性。 数学公式、代码块及交叉引用标签（如 {eq}、{prf:ref}）均完整保留，未出现破坏构建的格式错误 专业术语（如科布-道格拉斯、帕累托分布、洛伦兹曲线、对偶性等）翻译准确且与术语表保持一致 长句的拆分和重组符合中文学术写作习惯，长难句的因果、条件关系表达清晰自然 新增的大段内容（生产单元、固定系数、帕累托分布、活动分析、Levhari 逆问题等）在专业概念的传递上准确无误，未出现遗漏或误译

Suggestions:

• [minor · fluency] lectures/houthakker_aggregation.md — ## Fixed coefficients: 英文 'Houthakker assumes that cells are small and numerous, so that the cells exactly on the margin, which earn zero, can be neglected.' 中 'earn zero' 指利润恰好为零的边际单元，译文 '恰好处于边际（利润为零）的单元' 括注方式稍显生硬，但含义准确，不影响理解，仅风格可改进。 → 可译为 '恰好处于边际、利润为零的单元可以忽略不计'
• [minor · terminology] lectures/houthakker_aggregation.md — ## Later work: 'putty-clay vintage model' 被译为 '黏土-黏土式世代模型'，但 putty-clay 应为 '黏土-黏土' 的对应英文实际是 'putty'(黏土前)-'clay'(黏土后)两个不同状态，常见译法为 '可塑-黏土模型' 或 '黏土-黏土' 不准确，宜用 '易变-固化（putty-clay）投资世代模型' 或保留英文术语加注释，避免译文中前后重复同一个词导致误解其为同一材质。 → 黏土-黏土式世代模型 → 可改为 '可塑-黏土（putty-clay）投资世代模型'
• [minor · fluency] lectures/houthakker_aggregation.md — ### The CES case: 'Levhari applies the inversion to the CES production function' 译为 'Levhari 将反演方法应用于 CES 生产函数'，准确自然；但紧随其后 'Levhari writes α for our γ...' 段落中的符号对应关系翻译稍显直译，通顺度可以略微提升，例如在列举符号对应时增加适当连接词，使句子更流畅。
• [nit · fluency] lectures/houthakker_aggregation.md — ## Concluding remarks: 'such as cotton spindles' 译为 '例如棉纺锭'，准确，但该词在前文 '生产单元' 部分已译为 '纺纱机'（spinning frame），这里 'cotton spindles' 指的是另一种设备（棉纺锭/纱锭），译名统一且区分清楚，没有问题，仅供参考确认术语一致性。

🟡 Changes recommended

The TOC includes multiple references to a non-existent lectures/information_transfer.md, which is a critical issue likely to break jb build lectures due to missing documents (with an additional minor trailing-whitespace nit in the same file).

What changed in this PR

Automated zh-cn translation sync adding a new lecture on Houthakker’s aggregation result and integrating it into the lecture set via cross-references, TOC, bibliography, and translation state updates (with _toc.yml currently referencing a missing information_transfer lecture).

Changes:

• Add new translated lecture lectures/houthakker_aggregation.md plus translation state tracking
• Update wealth_dynamics and von_neumann_model to cross-reference the new lecture
• Update _toc.yml navigation and extend bibliography entries in quant-econ.bib

File	Description
lectures/​wealth_dynamics.md	Adds a brief cross-reference linking the wealth/Pareto discussion to the new Houthakker aggregation lecture.
lectures/​von_neumann_model.md	Updates lecture content/metadata and adds a cross-reference to the new Houthakker aggregation lecture.
lectures/​houthakker_aggregation.md	Introduces a new translated lecture explaining Houthakker-style aggregation from micro “cells” to a Cobb–Douglas aggregate production function with supporting figures/code.
lectures/​_toc.yml	Updates the book table of contents to include the new lecture and adjusts other TOC entries.
lectures/​_static/​quant-econ.bib	Adds bibliography entries needed for citations introduced by the new lecture/content updates.
.translate/​state/​wealth_dynamics.md.yml	Updates translation-sync state metadata for lectures/wealth_dynamics.md.
.translate/​state/​von_neumann_model.md.yml	Updates translation-sync state metadata for lectures/von_neumann_model.md.
