1 AJAE appendix for Stochastic Rangeland Use under Capital Constraints

Note: The material contained herein is supplementary to the article named in the title and published in the American Journal of Agricultural Economics (AJAE). 2 Appendix 1: Details on Sheep Biology Sheep biology relationships used in the current model are specified using information from a detailed sheep simulation model XLUMBE developed by Laca. XLUMBE is a Microsoft Excel implementation of the model by Finlayson, Cacho, and Bywater (1995), and it simulates daily changes in sheep body condition driven by daily nutrient intake levels. XLUMBE was parameterized for Kazakh Fine Wool sheep managed as generally indicated in figure A1 on a semi-desert rangeland in southeastern Kazakhstan. Forage production parameters used in XLUMBE are reviewed in Breuer (2000). For sheep parameters, the figures for wool-type sheep found in Finlayson, Cacho, and Bywater (1995) were used since this sheep breed is genetically close to Kazakh Fine Wool sheep. Following Degen and Young (2002), parameter adjustments were made for the impacts of climate factors such as weight losses due to cold weather
