Ejido Reforms in Mexico: Conceptual Issues and Potential Outcomes
研究了墨西哥村社系统私有化改革，构建了一个考虑自然与人类互动的风险分散模型，预测私有化在灌溉基础设施完善的村社土地上最易成功。
The evolving privatization of the ejido system in Mexico represents a challenge to standard economic models of common property regimes. These models tend to emphasize human interrelations while discounting the ecological conditions which form the environment for human interactions. A risk-spreading, safety-first model capturing interrelationships between nature and humans is developed to analyze the potential implications of Mexico's privatization efforts. Recognizing that the majority of ejido lands are communal, not parcelized, located primarily in arid areas, the model supports the prediction that privatization will occur and be most successful on irrigated, ejido lands with modern social and economic infrastructure.
