The Arrival of Fast Internet and Employment in Africa
利用海底互联网电缆逐步铺设和陆地光缆网络地图，研究发现快速互联网显著提高了非洲12个国家的就业率，包括低教育群体，且未导致空间上的岗位转移。
To show how fast Internet affects employment in Africa, we exploit the gradual arrival of submarine Internet cables on the coast and maps of the terrestrial cable network. Robust difference-in-differences estimates from 3 datasets, covering 12 countries, show large positive effects on employment rates—also for less educated worker groups—with little or no job displacement across space. The sample-wide impact is driven by increased employment in higher-skill occupations, but less-educated workers’ employment gain less so. Firm-level data available for some countries indicate that increased firm entry, productivity, and exporting contribute to higher net job creation. Average incomes rise.
