Promoting public health with blunt instruments: Evidence from vaccine mandates

Area of Science:

• Public Health
• Health Economics
• Labor Economics

Background:

• The U.S. healthcare industry faces persistent worker shortages predating the COVID-19 pandemic.
• COVID-19 vaccine mandates introduced in 2021 present ambiguous potential effects on healthcare employment.
• Mandates could either attract workers by increasing safety perceptions or deter them due to vaccine hesitancy.

Purpose of the Study:

• To analyze the impact of state-level COVID-19 vaccine mandates on healthcare industry employment.
• To investigate the effects of these mandates on employment transitions into and out of the healthcare sector.
• To quantify the association between vaccine mandates and healthcare workforce shortages.

Main Methods:

• Utilized monthly Current Population Survey data from 2021 to 2022.
• Employed difference-in-differences methods to assess the causal impact of state mandates.
• Examined changes in the probability of working in healthcare and employment flows.

Main Results:

• State vaccine mandates were associated with a 6% decline in the probability of working in the healthcare industry.
• The negative employment effects were more pronounced among workers in healthcare-specific occupations.
• Workers in healthcare-specific roles left the industry at higher rates and were replaced more slowly following mandates.

Conclusions:

• COVID-19 vaccine mandates may exacerbate existing healthcare workforce shortages.
• Policymakers face trade-offs between public health mandates and workforce stability.
• The findings highlight the complex interplay between health policy and labor market dynamics in the healthcare sector.
