Summary
The Paycheck Protection Program (PPP) helped small businesses retain jobs during COVID-19. Analysis shows PPP boosted employment by up to 5% at its peak, saving millions of jobs.
Area of Science:
- Economics
- Public Policy
- Labor Market Studies
Background:
- The Paycheck Protection Program (PPP) was a key fiscal stimulus during the COVID-19 economic shock.
- It aimed to help small businesses maintain employment and wages amidst the crisis.
- Eligibility for PPP was based on industry-specific firm-size cutoffs.
Purpose of the Study:
- To estimate the causal effect of the PPP on employment at eligible firms.
- To compare employment trends in PPP-eligible versus PPP-ineligible firms.
- To quantify the impact of the PPP on job retention and wages.
Main Methods:
- Utilized high-frequency administrative payroll data from ADP, a major payroll processor.
- Employed a comparative analysis of PPP-eligible and PPP-ineligible firms.
- Estimated the causal impact on employment evolution over time.
Main Results:
- The PPP led to a peak employment boost of 2% to 5% at eligible firms by mid-May 2020.
- This employment boost decreased to between 0% and 3% by the end of 2020.
- An estimated 3.6 million jobs were retained by mid-May 2020 and 1.4 million by year-end due to PPP.
Conclusions:
- The PPP demonstrated a significant, albeit temporary, positive impact on small business employment.
- The program played a crucial role in mitigating job losses during the pandemic.
- The cost per job retained was substantial, ranging from 3.4 to 5.2 times median earnings.
