Channel systems for conducting monetary policy are becoming increasingly popular. Despite its popularity, the consequences of implementing policy with a channel system are not well understood. We develop a general equilibrium framework of a channel system and study the optimal policy. A novel aspect of the channel system is that a central bank can “tighten” or “loosen” its policy without changing its policy rate. This policy instrument has so far been overlooked by a large body of the literature on the optimal design of interest-rate rules. 相似文献

Many environmental problems are due to damage caused by pollutants that accumulate with a time lag following their emission. In this study, we focus on nitrates used in agriculture, which can pollute groundwater many years after their initial application. A dynamic optimal control problem with heterogeneous farmers is proposed. The usual structural parameters such as the discount rate, the natural clearing rate and the lagged time interval between the occurrence of soil‐level pollution and the impact on groundwater are taken into account. We also examine pollution as caused by a continuous set of farms characterised by their individual performance index and by their individual marginal contribution to the pollution. The issue is further investigated by taking account of change in the information context, successively related to perfect information and to asymmetric information. As a result, when the delay between the spreading of N‐fertilizer and the impact on the aquifer increases, that is, the longer the lag, the steady‐state pollution stock and the steady‐state shadow price of the stock both increase. Moreover, we show that the optimal regulation may require a decreasing amount of fertilizer over time, even in the case of initial underpollution. 相似文献

In most of the largest U.K. local authorities the financial control function is highly centralised with no qualified accountant or controller located in each spending department. There now may be the beginnings of a trend towards employing accountants within service departments. The paper analyses how this new segment of public sector accounting appears to be becoming established, how the role of these accountants is being developed and the contrasting occupational values of accountants in service departments and those in the finance department. It is also shown how the existence of a strong accounting profession in local government can lead to different aspects of both the financial control structure and process in comparison with central government such that research results on the latter may not automatically hold at local level. 相似文献
