Modelling an aggregate agricultural panel with application to US farm input demands
讨论了一类新的要素需求模型，并用美国州级生产数据分析发现，标准灵活模型被更一般灵活的模型所替代，且各州的条件自价格弹性存在显著异质性。
A recent class of factor demand models is discussed and used to analyse US state-level production data. The approach accommodates output risk, heterogeneous technologies, technological change, endogenous variables, aggregation across agents and more general flexible functional forms than previous models. We find the approach to flexibility found in the consumer literature empirically useful in the analysis of producer behaviour as our results suggest that standard flexible models that have been ubiquitous in agricultural and industrial research are strongly rejected here in favour of a more general and flexible specification. Further, there is substantial heterogeneity of conditional own-price elasticities across states.
