Regulation of relationships between heterogeneous farmers and an aquifer accounting for lag effects

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.     

Why do financial systems differ? History matters

We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different financial structures. Because setting up financial markets is costly in our model, economies that emphasize bank lending are more likely to continue doing so in the future, all else equal.     

“The everyday accountant and researching his reality”: Further thoughts

It is the contention of this paper that accounting researchers have been dominated in thier research methodology by methods supposedly adopted from the natural sciences. It is argued that it is time that attention was paid to the possible use of radically different “naturalistic” (or “interpretive humanistic”) research approaches in order both to focus research more closely on the concerns of practitioners and to give greater insight into everyday effects of accounting and the practices of accountants themselves.     

A work role perspective of accountants in local government service departments

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.     

THE FUTURE ROLE OF THE LAW

1. All individual labour relations disputes arising out of breach of contract of employment including unfair dismissal should be capable of being settled by the relatively rapid, inexpensive and informal procedures of the industrial tribunals with further appeal on points of law; 2. The minimum condition of legal recognition for the closed shop should be the effective strengthening in law of protection for the individual union member or prospective member, subject to discretion concerning ‘disruptists7rsquo; 3. In the central area of collective labour relations, the following policy suggestions are made: a) criminal or civil sanctions against individual employees are impractical and best forgotten. Sanctions can only be realistically considered in relation to leaders and organisations; b) the objective for a rational law of strike action (or other forms of direct action) should be limited if it is to be realistic, i.e., not the chopping down of managerial or trade union or shop floor power but insistence on a reasonable degree of orderliness and time for second thoughts in the run up to direct action; c) it is an ancient truth that only fair and reasonable laws will command respect. Disputes procedures are a kind of quasi-law. To command respect and to justify sanctions for its breach, a disputes procedure should be independently certificated as fair and reasonable in accordance with modern labour relations standards. The C.I.R. is at present the obvious body in which to vest this certificating power; d) where adequate procedures and principles are provided by the law to deal with an identified class of industrial dispute, the use of private power, including private collective power, to impose a solution should be legally discouraged.
