The optimal long-run fertilisation and irrigation of a perennial crop is approached via two stochastic dynamic optimisation models. The first model assumes that the ex-post level of the state variable--leaf nitrogen (LN)--is known with certainty. The second model assumes that the level of leaf...

The efficiency of agricultural inputs may be reduced by ignoring the inherent variability in soil texture and the non-uniformity of the input's application. This paper focuses on variable-rate irrigation, which is performed via subdivision of the spatially variable field area into a controlled...

Groundwater has the characteristics of commonly owned property, and its use is likely to be inefficient in the absence of regulation. Several management tools can be used to regulate groundwater withdrawals, with no one tool dominating the others in terms of efficiency of water use. However, the...

A theory of settlement planning focussing on village-level production services is presented, and settlement plans are compared. The analysis draws on the modern theory of local public goods. Conditions for optimal level of services and optimum settlement size are derived, together with rules of...

The well-known Allais paradox is reformulated as a daily farm decision problem. Only 26% of the farmers exhibit violations of the expected utility hypothesis. Moreover, the tendency for violation decreases with the farm operator's education, experience and family size. No effects of the farm...

A theoretical framework is developed to study the effects of socioeconomic factors on farmers' risk attitudes and production decisions. No maintained assumptions about the individual's utility are required. A key element in this framework is the categorization of socioeconomic factors by their...

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework. The analysis provides a conceptual and...
