This document summarizes Peter van de Ven's presentation on the implementation of the 2008 System of National Accounts (SNA) and future challenges for national accounts. It discusses key changes in the 2008 SNA, such as the treatment of R&D, pensions, and holding companies. It also examines major challenges, including the globalization of production, aging populations, and accounting for knowledge economies. The presentation argues that future revisions will focus on developing supplementary modules to address issues like analyzing multinational enterprises and measuring human capital.
