| Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average... |

| Our object is to develop a method for the public approval and re-evaluation of pesticides that emphasises a wide evaluation of social benefits. This is done through the case for the three plant-growth regulators approved for use in Norwegian grain production at present: chlormequat chloride, ethephon and trinexapacethyl. A multicriteria method is founded on the premises for an expert based model as opposed to e.g. a market based model. It seems to be a possible method that allows for the use of several incommensurable criteria in the approval process by National Agricultural Inspection Service (NAIS). Furthermore, it results in greater transparency, which may be an important quality in a public decision process. However, there are problems connected to a... |

| LP models of Norwegian dairy farms are designed to evaluate the impact of changes inprices and subsidies on production systems and on profitability at the farm level. At 1999-prices, producing a fixed milk quota with low to moderate yielding cows (6000 to 6600 kg milk annually) is most profitable. Silage offered ad libitum is profitable. Athree cut harvesting system is more profitable than two cuts. Changes in the milk pricehave no effects on production. If forage crops is the only possible land use, increased area payments have no effects on production. If non-forage crops are also grown,increased area payments for forage crops result in a higher proportion of the land being used for temporary grass (ley) and in cheaper forage, making higher silage intake... |

| The EU regulation governing organic production will require 100% organic feed in organic dairy systems from August 2005 compared with 85% currently in Norway. This study aimed to assess adjustments in resource use and financial impacts on organic dairy herds using a discrete stochastic programming model. Farm management effects of the regulatory change varied between farm types. For the two organic dairy systems examined, both having a milk quota of 100 000 litres but with varying farmland availability, the introduction of the 100% organic feed regulation resulted in an economic loss of approximately 6-8% of the net income compared to the current regime. The economic loss was mainly due to the considerable higher price of organic compared to conventional... |

| The objective of this study was to provide empirical insight into dairy farmers' goals, relative risk attitude, sources of risk and risk management responses. The study also examines whether organic dairy farming, leads to important risk sources not experienced in conventional farming and, if so, how those extra risks is managed. The data originate from a questionnaire survey of conventional (n=370) and organic (n=160) dairy farmers in Norway. The results show that organic farmers have somewhat different goals than conventional farmers, and that the average organic farmer is less risk averse. Institutional risk was perceived as the most important source of risk, independently of conventional or organic production system, while organic farmers indicated... |
