H.R. 1756 would authorize the appropriation of $2.5 million for each of fiscal years 2023 and 2024 for the Bureau of Economic Analysis to study the contributions of different income groups to gross domestic product. CBO estimates that enacting H.R. 1756 would not affect direct spending or revenues. CBO estimates that implementing the bill would increase discretionary costs by $5 million over the 2023-2027 period, but that spending would be subject to the availability of appropriated funds. The bill contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act.
