| While rotation strategies are important in determining agricultural commodity supply and environmental benefits from land use, little has been said about the economics of crop rotation. An issue when seeking to identify rotation dominance is whether yield and input-saving carry-over effects persist for one or more years. Focusing on length of carry-over, expected profit maximization, and the monoculture decision, this paper develops principles concerning choice of rotation structure. For some rules that we develop, rotations may be discarded without reference to price levels while other rules require price data. We also show how risk aversion in the presence of price uncertainty can alter preferences over rotations. A further consideration in rotation... |

| The purpose of this paper is to evaluate the jointness between agricultural production and ecosystem services using a spatial explicit economic-ecological programming model. Thereby, the consideration of non-agricultural competitors in the provision of ecosystem services allows a simultaneous assessment of economies of scope. A cost-effectiveness analysis for a case study region in Switzerland shows the least costs supplier of ecosystem services and spatial patterns in the supply for these services. Results imply strong jointness between agricultural production and the provision of ecosystem services. However, the potential for cost savings is considerable. |

| When public goods are joint outputs of agricultural production, there is a trade-off between agricultural and non-agricultural provision of the public good. The principle of minimal price distortion in the reform of agricultural policies has led to a theoretical recommendation that public goods, if under-provided at agricultural free market level, should be promoted through non agricultural policies instead of agricultural policies. We show that the economies of scope between the agricultural production and the joint public good play a key role in determining the optimal way of providing this latter. If the policy designed is a non-agricultural policy, the production cost of the public good is higher than with an agricultural policy. If the policy designed... |
