| This paper uses a directional output distance function to estimate a multi-output production frontier for a sample of experimental plots grown for the Sustainable Agriculture Farming Systems project at the University of California, Davis. Cross-sectional technical efficiency indices are estimated that take into account two proxies for undesirable output: number of trips across a field as a proxy for air pollution and/or soil erosion, and pints of pesticides applied to account for potential leaching and/or health risks. Shadow price estimates based on marginal rates of transformation ranged from $8-$21 for trips, while shadow prices for pints of pesticides averaged $23-$27. |

| In crop-livestock mixed farming system where farm yard manure (FYM) is considered as important multi-purpose resource such as source of soil organic matter, additional source of income and household source of energy, soil fertility depletion could takes place within the perspective of the household allocation pattern of FYM. This paper estimates structural FYM-allocation model in the presence of corner solution, with the objective of examining the role of various returns to FYM and farmer’s impatience on the propensity to allocate FYM for alternative purposes. We illustrate the model using data based on a random sample of 493 farm households in the central highlands of Ethiopia. We find that the higher the selling price of FYM is the higher the incentive... |
