Nutrient emissions from pastoral agriculture are a global cause of declining water quality. Their management is complicated through variability arising from climate and soil influences. This paper compares the implications of input‐based policies and direct restrictions on leaching to achieve 10 and 20 per cent reductions in nitrogen (N) load, in the context of pasture‐based New Zealand dairy farms. The most important mitigation practices on these farms are de‐intensification (involving reductions in N fertiliser application and stocking rate) and the application of nitrification inhibitors. A stylised conceptual model, incorporating both sources of variability, is used to identify the implications of alternative policies. Direct restriction of estimated N leaching is the most cost‐effective policy to reduce N leaching by 10 and 20 per cent. These results indicate the general insufficiency of input‐based mechanisms for water quality improvement, given the low correlation between input use and leaching, possible substitution with unrestricted inputs and their failure to motivate the use of mitigation strategies. Additionally, model output indicates that inherent variability in water quality, mainly due to climate influences, can dominate the benefits of regulatory action in any given year. 相似文献

The author discusses the role of the ACCC in promoting competition policy in Australia. The ACCC's regulatory activities in focusing on of those industries where competition is limited are examined. It is argued that the focus here is two fold: to create conditions for fair competition in industries that rely on the services of facilities with natural monopoly characteristics and the administration of price caps to minimise the impact of monopoly power. 相似文献

The paper presents a critique of tourism policy in London in the context of local environmental plans and central government policy for tourism and hotel development. Rationales for local authority tourism policies are assessed in relation to city‐level planning imperatives and local land‐use plan formulation. A comparative analysis of borough development plans and the treatment of tourism is based on a survey of London's 33 unitary authorities. The paper presents a World City case study of urban tourism from the position of the environmental planning process and in the light of the highly concentrated distribution of hotel provision and tourist activity in London.

Most U.S. states have enacted JSL reform, the move from a regime of joint and several liability (JSL) that allows plaintiffs to claim full recovery from any one of multiple defendants to one where defendants are held liable only for the harm they cause. Contrary to previous theoretical work, we show that JSL reform can increase precaution by judgment proof agent by giving “deep pockets” an incentive to reduce their own liability by bringing judgment‐proof agents into court. This result can help explain our empirical findings showing that JSL reform reduces death rates (and hence increase precaution) for many types of accidents. Together, these results highlight the role that litigation costs and judgment‐proof agents play in the functioning of the American tort system. 相似文献

This paper examines the typical treatment of “effort” by both efficiency-wage theorists and principal-agent theorists. These theorists do not justify regarding effort as a cardinal variable. Yet, if effort is an ordinal variable, certain assumptions which are routinely invoked are literally devoid of meaning. Indeed, the precise expression of a complicated truth cannot possibly take a simple form, however precise-looking the simple formula might be. A formal expression can be extremely precise without being at all a precise representation of the underlying concept to be captured. 相似文献

The concept of "fair value" is increasingly being incorporated into Australian and international accounting standards and pronouncements. The fair-value concept has also been established and developed in Australian legal cases, and an examination of pertinent court decisions is of interest to accountants. By examining and analysing relevant cases, the paper highlights some of the principles and difficulties involved in operationalising the fair-value concept for accounting and legal purposes, particularly in situations where the asset being valued is subject to imperfect or incomplete markets. 相似文献
