DP19260 Exporting Ideas: Knowledge Flows from Expanding Trade in Goods

We examine the effect of entry by French firms into a new export market on the dynamics of their patents’ citations received from that destination. Applying a difference-in-differences identification strategy with a staggered treatment design, we show that: (i) entering a new foreign market has a significant impact on the long-run flow of citations; (ii) the impact is mostly driven by the extensive margin; (iii) inventors in destination countries patent mostly in products that do not directly compete with those of the exporting firm; (iv) the spillover intensity decreases with the technological distance between the exporting firm and the destination.
