From 9df2429ca6d970eaa022dd607f12a8b22cd04d9e Mon Sep 17 00:00:00 2001 From: PavelMakarchuk Date: Thu, 8 Oct 2026 09:41:42 -0400 Subject: [PATCH] BLS deck: name PolicyEngine's users on the NBER slide On slide 8, the PolicyEngine "Used in research and policy" item now names users from slide 6: "Joint Economic Committee, BEA, universities and benefit navigators", in place of "Congress, think tanks, benefit tools". The title stays parallel with the TAXSIM side.

Close with: both teams validate the emulator, and the work has improved how both TAXSIM and PolicyEngine encode tax law. TAXSIM has run at NBER since the 1970s; NBER still maintains it, and more than 1,200 papers cite the 1993 paper that introduced it. Think tanks such as Brookings and federal agencies rely on it. NBER started filing differences on the emulator’s public GitHub tracker in 2024 (first issue: September 22, 2024). The memorandum of understanding with NBER was announced on September 5, 2025. policyengine-taxsim 3.0.0 was released on September 29, 2026, one of 80 PyPI releases since February 2026. One interface covers every tax year: TAXSIM35 handles 1960–2020 (state law from 1977) and PolicyEngine handles 2021 onward. PolicyEngine facts (right): public code since June 2021, 133 contributors to the US model, 95,000+ parameters and 4,693 test files, from the gettsim-2026 deck (September 3, 2026); check them before the talk. The benefit list follows the Benefits and taxes section of policyengine.org/us/taxsim, which also names housing vouchers, the EITC and the CTC. Optional context for this audience, not on the slide: the CE published TAXSIM-based tax estimates from the 2013 data through the 2023 data, and the 2024 data has none (BLS Monthly Labor Review, 2015; CE PUMD Getting Started Guide).
