The New UK Monetary Arrangements: A View From the Literature
分析1997年英国新货币安排的特点，指出通胀目标合同不完整，但通过估计最优政策边界，认为央行只需假设政府偏好合理即可避免问题。
This paper considers the likely operating characteristics of the new UK monetary arrangements introduced in May 1997. The paper first argues that the time inconsistency of policy is not an issue provided the Bank of England is properly independent. However, the current inflation remit from the Chancellor to the Bank specifies a numerical target for the inflation rate, but does not specify how quickly deviations from the target are to be corrected. It is thus an incomplete contract, and there is a danger that the Bank may choose to stabilise inflation at the cost of excessively volatile movements in output, or vice versa. We estimate the optimal policy frontier for the UK economy and show that in practice it is close to rectangular. Consequently all the Bank needs to assume is that the government's preferences are ‘reasonable’ in order to know approximately where to locate on this frontier; the incompleteness of the remit therefore need not be a cause for concern.
