By analyzing a unique dataset from Germany’s evaluation of COVID-19 antigen rapid tests, we show that Chinese firms can excel under today’s global competition and produce tests at quality levels higher than China’s income level would suggest. We find these achievements are positively...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...
