The impact of flexibility at work on fertility
利用挪威首次新冠封锁作为工作灵活性增加的实验，发现生育率显著且持久地提高了10%，且集中在原本灵活性低的“贪婪工作”中的高收入女性，表明灵活性缓解了职业与家庭的权衡。
Leveraging the first Covid-19 lockdown in Norway as a laboratory for an increase in work flexibility, we uncover a significant and persistent 10% increase in births. Using the Goldin (2014) measure of work flexibility based on occupation characteristics, we show that fertility increases were concentrated among women in “greedy jobs” with lower flexibility prior to lockdown. We formalize this intuition in a theoretical model where a rise in flexibility increases a woman’s time budget and boosts the fertility of higher earning women. The increase in work flexibility under Covid-19 lockdown allowed high-earning women in inflexible jobs to alleviate the career-family trade-off.
