Fons-Rosen, Christian; Pu, Zhaoxin (2023). The Transmission of Sectoral Shocks Across the Innovation Network, CEPR Discussion Paper, DP17960.

  • We use a firm-level panel of 13 European countries to assess how a sector-specific shock propagates through technological linkages across innovating firms in the rest of the economy. We find that the competition shock to the European textile sector, induced by the 2001 removal of import quotas on Chinese textiles, had a strong negative effect on non-textile firms' patenting and knowledge sourcing. These firms end up diversifying their patenting across more technological categories and start citing more (geographically and technologically) distant sources of knowledge. When aggregating data at the country level, the negative indirect effect on patenting of non-textile firms can be 3 to 5 times as large as the positive direct effect on textile firms.

Gaessler, Fabian; Pu, Zhaoxin (2018). Openness as Platform Strategy - Evidence from a Quasi-Experiment in Crowdfunding, Max Planck Institute for Innovation & Competition Research Paper, No. 18-05. DOI

  • A platform's decision to open up its marketplace is at the core of its business strategy. It needs to balance between the benefits of market thickness and the costs of potential congestion and quality concerns. We discuss how openness can increase platform value and test our hypotheses by analyzing the strategic decision of a leading crowdfunding platform to switch from access control to de facto openness. The decision increased market thickness on the previously access-controlled supply side of crowdfunding projects. The platform hereby gained market share from its main competitor. Market matches on the platform increased in absolute but not in relative terms. Moreover, quality on the supply side declined immediately, lowering platform value for demand-side users.
