The Margins of Multinational Production and the Role of Intrafirm Trade
研究了公司内贸易如何影响跨国生产的地理分布，发现跨国生产与出口活动非常相似，关闭跨国生产会导致相对较小的福利损失。
Multinational production (MP) can lead to large gains through international technology sharing. However, empirical evidence suggests that geography matters for MP: Affiliate sales fall in distance from the headquarters. We introduce intrafirm trade into a standard model of exports and MP and show that the model is consistent with firm-level and aggregate evidence. Using a maximum likelihood estimator, we find that intrafirm trade plays a crucial role in shaping the geography of MP. An implication of our work is that MP and exports are very similar activities. Consequently, shutting down MP leads to relatively small welfare losses.
