CEO @MaxGhenis, joined the #PN3PolicyAcademy where he introduced teams to @ThePolicyEngine, a free, open-source platform that enables users to simulate reforms like state #EITCs and analyze how these policies affect household resources. #PolicyImpact #TaxCredits #PolicyDesign


BREAKING: PolicyEngine's microsimulation model projects a surge in candy consumption in the coming hours. Happy Halloween! 🎃

California's proposed billionaire tax creates marginal rates of 50-60% on wealth between $1.0-$1.1 billion due to its phase-in structure. We analyzed the math behind Initiative 25-0024:

How would changing the VAT threshold from £90k affect revenues? Our new firm microsimulation model shows: • £70k threshold: +£642m revenue • £100k threshold: -£371m revenue • £120k threshold: -£1.1bn revenue All estimates for 2026-27.

🤝 Big news: PolicyEngine and @nberpubs have signed an MOU to ensure researchers worldwide continue accessing critical tax microsimulation tools. We're building an open-source TAXSIM emulator, combining NBER's 50+ years of tax expertise with modern open-source infrastructure.

New: @Arnold_Ventures used PolicyEngine to compare taxes between TCJA expiration and House & Senate reconciliation bills, with $30k SALT cap. Married filers with one child, income of $250k/$500k, and 90th percentile deductions pay less tax under reconciliation bills in CA/NY/NJ.

New analysis: The 2025 American Family Act would expand the Child Tax Credit to $4,320 for children under 6 and $3,600 for children 6-17, with a $2,400 baby bonus for newborns. Our microsimulation shows the policy would cost $2.5 trillion over 10 years and cut child poverty 25%.
