This study proposes a novel channel through which trade liberalization may induce innovationthrough the reduction of trade policy uncertainties (TPU) in destination markets. To verify thislinkage, we utilize the significant reduction of TPU engendered by China’s accession to theWorld Trade...

To understand the effects of trade policy uncertainty on firm-level export decisions, we study firm-product data on Chinese exports to the U.S. in the years surrounding China's 2001 WTO accession. Following predictions based on a model of heterogeneous firms, we provide empirical evidence that...
