Does attention‐deficit hyperactivity disorder medication reduce entrepreneurship?
利用11个国家和1个特别行政区的面板数据，研究发现成人ADHD药物使用增加与有限责任公司注册减少相关，提示药物治疗可能意外抑制创业活动。
Attention-deficit hyperactivity disorder (ADHD) is a highly inheritable condition with a rather stable prevalence over time and geography, and it is associated with a broad range of negative life outcomes. Increasing knowledge on the condition has led to a growing trend of dampening ADHD symptoms through medication. Although this development has led to many positive outcomes, the broader societal implications are still poorly understood. In particular, person-level studies suggest that ADHD-like behavior may possess some advantages for engaging in entrepreneurship and the initiation of new businesses, which is considered a key activity for economic development. Using recent panel data from 11 countries and one special administrative region (SAR), we investigate if the increasing use of ADHD medication in adults is associated with an unintended outcome of reducing entrepreneurship. We find that a roughly one unit increase in the prevalence of adult ADHD medication is associated with a one unit decrease in limited liability company registrations per working age population. In practical terms, the effect of a one within-country/SAR standard deviation increase of adult ADHD medication prevalence corresponds to a decrease in new business formation of 20% of its mean in the sample.
