Jwe Identification

ASecurity

Use when the identification strategy is the bottleneck for a 《世界经济》 (The Journal of World Economy) manuscript — external shocks (tariffs, trade agreements, exchange-rate reforms, FDI negative-list) as quasi-experiments, plus shift-share / Bartik and gravity designs. Stress-tests exogeneity and inference, including the modern shift-share critiques.

# 开放经济识别策略(jwe-identification)

> 在《世界经济》(IWEP + 中国世界经济学会主办,月刊),识别策略的外生变动最好锚在**国际/制度性冲击**上(关税战、入世、汇改、外资负面清单、全球需求冲击),而非国内政策的副产品——这是本刊区别于综合性/金融类期刊的识别口味。shift-share 与引力-PPML 是本刊高频设计,其现代推断批评(GPSS/BHJ/AKM)也是本刊审稿人高频追问点。基础事实见 `resources/journal-profile.md`。

## 触发时机

- 实证主体仅 OLS + 控制变量,外生性靠"我们认为"
- 用 shift-share / Bartik 暴露度但不讨论 exposure 外生性与推断
- 引力模型用 OLS-log、零贸易直接丢
- 有外部冲击但没想清"为何对个体外生"

## 设计优先级(开放经济场景)

1. **外部 / 制度性冲击 + DID / event-study**:关税战、入世、自贸区、汇改、外资负面清单
2. **shift-share / Bartik 暴露度**(进口渗透、出口需求冲击)——需现代推断
3. **引力模型(PPML)** 估贸易政策(协定、关税)效应
4. **IV**(外部冲击作工具,论证排他性)
5. OLS + 严密外生性讨论(理论实证 / 结构估计中可接受)

## 分支路径

### 分支 A:外部冲击 DID / event-study
- 冲击是否真外生于个体(关税由贸易伙伴决定 / 政策非内生于被处理者)?
- staggered 处理 → 用 Goodman-Bacon 分解 + Callaway-Sant'Anna / Sun-Abraham,别裸用 TWFE
- 平行趋势:事件研究图必画;安慰剂(随机处理时点 / 对象)
- 预期效应:被处理者是否提前响应(前置项)

### 分支 B:shift-share / Bartik(重点)
- 暴露度 = 初期份额 × 共同冲击(如 ADH 的进口渗透)
- **现代推断批评必须回应**:
  - Goldsmith-Pinkham-Sorkin-Swift:识别力来自**份额**,须检验份额外生、报告 Rotemberg 权重
  - Borusyak-Hull-Jaravel:识别力来自**冲击**,须冲击层面随机性 + 相应推断
  - Adão-Kolesár-Morales:标准误须按暴露结构调整(常规聚类会过度拒绝)
- 至少报告:份额外生性论证、Rotemberg 权重 top 来源、shock-level 或 exposure-robust 标准误

### 分支 C:引力模型
- **用 PPML**(Santos Silva-Tenreyro)处理异方差与零贸易,别用 OLS-log
- 进出口国×年 + 国家对固定效应(multilateral resistance)
- 贸易政策变量(协定 / 关税)内生性:滞后 / IV / 事件研究

### 分支 D:IV(外部冲击为工具)
- 第一阶段 F ≥ 10;弱工具用 Anderson-Rubin / weak-IV-robust CI
- 排他性三段论:理论 + 制度 + 安慰剂
- 报告 reduced form

## 必查清单

- [ ] 外部冲击对个体的外生性有制度 / 理论证据,不只"我们认为"
- [ ] staggered DID 回应了异质性处理偏误
- [ ] shift-share 报告份额外生性 + Rotemberg 权重 + exposure-robust SE
- [ ] 引力用 PPML + 多边阻力固定效应
- [ ] 平行趋势 / 安慰剂 / 弱工具 检验齐全
- [ ] 标准误聚类层次与暴露 / 冲击结构匹配

## 反模式

- shift-share 当普通 IV 用,标准误常规聚类、不提 exposure-robust 推断
- 关税 / 协定当外生但不论证对方为何这样定
- 引力 OLS-log 丢零贸易
- TWFE + staggered 不讨论 Bacon 分解

## 输出格式

```
【识别策略】外部冲击DID / shift-share / 引力PPML / IV / 结构
【外生性论证】制度□ 理论□ 安慰剂□
【shift-share 推断】份额外生□ Rotemberg□ exposure-robust SE□
【已完成检验】[平行趋势, 安慰剂, 弱工具, ...]
【缺失检验】[...]
【下一步】jwe-transmission-channel
