We conduct a meta-analysis of more than 30 papers that study the causal relationship between exporting and firm productivity. Our results, robust to different specifications and to different weights for each observation, indicate that the impact of exporting upon productivity is higher 1) at...

Electrochemical reduction of CO 2 to C2 products provides a promising approach for controlling the global carbon balance and restoring renewable surplus electricity, while the low CO 2 activation property and slow OC-CO coupling rate lead to unfavorable performance on Cu-based catalysts. Here we...
