Reliability and Robustness in Yield and Input Elasticities for Wetland Rice in Java
利用爪哇湿地水稻的合并时间序列数据，评估不同模型设定下产量和投入需求弹性的敏感性，发现产量和化肥弹性较稳健，但劳动力需求弹性对数据和模型设定敏感。
This study attempts to address the issues of "reliability" and "robustness" in the supply parameters using pooled time series data for wetland rice in Java. In particular, the sensitivity of the yield and input demand elasticities are evaluated due to differences in specification of farmers' expectations variables, alternative data sources, (dis)aggregation of inputs, and functional forms. The analysis indicates that the yield and fertilizer input elasticities are fairly robust across different specifications. However, the estimates of labor demand elasticities are quite sensitive to data and model specifications.
