Driver's licences for undocumented immigrants and post‐mortem organ donation
研究利用双重差分和事件研究法，发现向无证移民发放驾照的法律使持照司机增加约2.7%，进而使西班牙裔器官捐赠者增加28%，器官移植增加17%，有助于缓解器官短缺和缩小种族等待时间差距。
Abstract This study examines the relationship between expanded access to driver's licences among undocumented immigrants and the number of post‐mortem organ donors, using difference‐in‐differences modelling and event study estimation techniques. Results suggest that the adoption of laws that grant driver's licences to undocumented immigrants effectively increased the population of licensed drivers by about 2.7%. These increments eventually led to subsequent increases in the number of Hispanic organ donors by 28%, and the outcome is driven mainly by young adult Hispanic donors. Moreover, DLU laws are further credited with an approximately 17% increase in organ transplants, particularly among Hispanics, although transplant waiting list addition numbers are not significantly affected. As these laws pave the way for more undocumented drivers to register as organ donors, such legislation could help to alleviate organ shortage issues and narrow the ‘ethnic waiting period gap’ for organ transplants.
