This analysis utilises a model of production under risk estimatedon Finnish farm-level data to measure farmers' risk attitudesin a changing policy environment. We find evidence of heterogeneousrisk preferences among farmers, as well as notable changes overtime in farmers' degree of risk aversion. This result is dueto the increase in the non-random part of farm income generatedby the policy change after Finland's European Union accession.The analysis confirms the assertion that agricultural policiesthat are decoupled from production do affect input use and cropmix through their effect on farmers' risk attitudes. 相似文献

A study of 386 potential and current members of the accounting profession in Australia and South‐East Asia provides evidence of the importance of three attributes – brand/reputation, international recognition of qualifications and career opportunities – in the decision to join a professional accounting body. While these attributes are important, logit regression models indicate that they are not discriminatory in the choice of professional body and suggest a perception of a collective, undifferentiated accounting profession. The marketing of brand/reputation and membership benefits may be a more efficient and effective strategy in attracting members and differentiating the profession if undertaken by a combined or coordinated professional body. 相似文献

The variables that relate to cost of hospital care for a large sample of elderly patients at risk for falling are examined. The chief predictors of cost of hospitalization were medical, pharmacy, and nursing interventions. Use of nursing interventions, on average, raised the median hospital cost less than use of medical or pharmacy interventions. Using a standardized nursing language with the hospital's information system can provide nurses with information that demonstrates the cost effectiveness of their interventions. 相似文献

We develop a bioeconomic model of the northern Balticsalmon fishery that takes into account thesimultaneous harvest of wild and reared salmon. Weassess the optimal harvest allocation between thecommercial offshore, inshore, and estuary fisheries,and the recreational river fishery that sequentiallyharvest the salmon stock. We restrict the solution tospawning stocks sufficient to preserve the wildsalmon. Empirical results suggest closure of theoffshore and inshore fisheries. Optimal managementenhances the wild stock, and results in substantialeconomic gains to the fishery. Current fisheryregulation improves the performance of the fisheryover open access, but fails to utilize the fullproductive potential of the resource. 相似文献

Das kann die Plastische Chirurgie – Jedes Jahr erkranken in Deutschland etwa 55.000 Frauen neu an Brustkrebs. Vielen von ihnen
bietet nur eine radikale Brustamputation die Chance auf Heilung – ein verstümmelnder Eingriff für die Betroffenen. Doch heute
gibt es viele M?glichkeiten, diesen Frauen wieder zu einem positiven K?rperbild zu verhelfen. 相似文献

The paper puts forward a model of the Atlantic salmon fishery in the Baltic Sea that integrates the salient biological and economic characteristics of migratory fish stocks. Designed to be compatible with the framework used for actual stock assessments, the model accounts for age-structured population dynamics, the seasonal harvest and competing harvesting by commercial and recreational fishermen. It is parameterized for the Simojoki River stock. The socially optimal policy for maximizing discounted net benefits from the fishery within an uncertain environment is determined using a dynamic programming approach and numerical solution method. Our results indicate that substantial economic benefits could be realized under optimal management without compromising stock sustainability. 相似文献

This paper examines how non-binding cooperative agreements on fisheries management can be sustained when the management plans
in participating countries are implemented imperfectly, and compares the effects of implementation uncertainty and of recruitment
uncertainty on the potential for cooperation. The model developed assumes two countries that share a fish stock. Reproduction
depends on how much fish each country leaves behind after harvesting and hence on random variation in each country’s achieved
abandonment level. A self-enforcing agreement is proposed that accounts for the random variation. The agreement is illustrated
with a numerical example. A self-enforcing cooperative solution can only be sustained when uncertainty is not pronounced and
when the two countries control close to equal shares of the fishery. Even when a cooperative agreement can be achieved, frequent
phases of reversion to non-cooperative harvest levels are needed to support the agreement. A comparison of the effects of
recruitment and implementation uncertainty on implicit cooperation indicates that implementation uncertainty is more likely
to hamper cooperation. 相似文献

Many environmental problems involve the transformation of multiple harmful substances into one or more damage agents much
in the same way as a firm transforms inputs into outputs. Yet environmental management differs from a firm’s production in
one important respect: while a firm seeks efficient input allocation to maximize profit, an environmental planner allocates
abatement efforts to render the production of damage agents as inefficient as possible. We characterize a solution to the
multiple pollutants problem and show that the optimal policy is often a corner solution, in which abatement is focused on
a single pollutant. Corner solutions may arise even in well-behaved problems with concave production functions and convex
damage and cost functions. Furthermore, even concentrating on a wrong pollutant may yield greater net benefits than setting
uniform abatement targets for all harmful substances. Our general theoretical results on the management of flow and stock
pollutants are complemented by two numerical examples illustrating the abatement of eutrophying nutrients and greenhouse gases. 相似文献

The German “Energiewende” is progressing more slowly than intended. Despite of high feed-in tariffs, private investors remain cautious due to the risk profiles, especially in offshore wind. Sensitivities of DCF-based investment models confirm material risk impact, especially from lower wind availability and construction cost overruns. Political focus on the timely grid connection of regional feed-in tariff differentiation may not address investor needs, with the result that this will remain costly. The forthcoming updates to the renewable energy law should seek to mitigate wind availability risk; ease contributions from insurance companies, pension funds and private equity; and support financial innovation. 相似文献
