Chile has embarked on an ambitious path towards a new constitution. For all countries, drafting a new constitution or amending an existing one is a stimulating challenge, but also a demanding process from both a political and technical standpoint. This report presents the results of a benchmarking exercise conducted by the OECD of possible constitutional provisions, reflecting the experiences of OECD member countries. The components covered include economic and social rights, the system of government, multi-level governance, constitutional review, fiscal governance and the role and functioning of central banks.
