Estimating the Structure of Agricultural Investment: A Stochastic- Coefficients Approach
用灵活加速模型和随机系数模型两种方法估计农业总投资结构，发现两者调整率估计不同，但随机系数模型在样本外预测中表现更好。
Two approaches, a flexibie-accelerator model and a stochastic-coefficients alternative, are used to estimate the structure of aggregate agricultural investment. Structural estimates of the adjustment rates for each model differ. The stochastic-coefficients model, however, performs better in out-of-sample forecasting.
