The Economics of Harmonisation: Implications for Reform of Commercial Law and Regulation in New Zealand

This paper provides an economic assessment of the costs and benefits of harmonising New Zealand's commercial laws and regulations with those in Australia or with an OECD norm. It argues that unless the definition of harmonisation is limited to mutual recognition the economics literature surveyed does not support a general presumption in favour of harmonisation of commercial laws.The absence of any presumption in favour of harmonisation is based on the infeasibility of full harmonisation while New Zealand maintains political independence and on the overall requirement for an assessment of the efficiency of any law in the context of the New Zealand economy
