Estimating Input Use and Production Costs From Farm Survey Panel Data
研究了利用面板数据估计农场投入使用和生产成本的方法，相比传统最小二乘法有改进，但仍有实际问题和方法论挑战。
Econometric estimation of enterprise input use and production costs offers a less expensive alternative to special surveys. Estimates of input allocation are of use within programming models, for policy analysis and income forecasting. However, simple ordinary least squares estimation has been plagued by a number of problems and the results have been disappointing. This paper provides some empirical evidence on the extent to which these problems can be overcome, or at least mitigated, through exploitation of panel data sets and appropriate panel data estimation techniques. The results confirm that this approach provides some improvement in estimation results, but some practical and methodological problems remain.
