Automation and population growth: Theory and cross-country evidence
研究了人口增长放缓与自动化之间的关系，发现人口增长率每提高1%，机器人密度增长率约降低2%，基于60个国家1993-2013年的面板数据。
We analyse the relationship between declining population growth and automation. Theoretical considerations imply that countries with lower population growth introduce automation technologies faster. We test the theoretical implication on panel data for 60 countries over the time span 1993–2013. Regression estimates support the theoretical implication, suggesting that a 1% increase in population growth is associated with an approximately 2% reduction in the growth rate of robot density. Our results are robust to the inclusion of standard control variables, different estimation methods, dynamic specifications, and changes with respect to the measurement of the stock of robots.
