Cost‐benefit analysis in financial regulation: How to do it and how it adds value

The proposed contents of the planned Financial Services and Markets Act have been revealed in the draft bill (FSMB) that was introduced into Parliament on 17 June, 1999 and in various announcements by the government. On that basis, the Act is expected to require the Financial Services Authority (FSA) to have regard, in discharging its functions, to the economic impacts of the provisions it makes and to publish a cost‐benefit analysis (CBA) of proposed rules and general guidance with respect to the operation of rules. This paper describes the technical and organisational measures that the FSA is taking in order to fulfil the FSMB's requirements for CBA and considers the rationale for those requirements. The paper suggests that the case for undertaking cost‐benefit analysis rests on the dangers of interfering in markets without analysing the likely consequences in a rigorous and theoretically sound manner. The paper also reviews the (so far limited) experience of applying cost‐benefit analysis to financial regulation in the UK and suggests how difficulties in the assessment of the costs and benefits can be addressed, with a consequent increase in the value of financial regulation.
