Supply response for Greek cereals
修改了Nerlove传统模型，采用理性预期模型考察1961-1982年希腊谷物供给对价格变化的反应，并纳入天气和技术进步因素，发现农民对价格有一定响应但程度因产品而异。
Given the criticism of Nerlove's traditional model, an attempt is made to present a critical empirical examination of it. More specifically, a modification of the Nerlovian model to a rational expectations model is developed and employed to investigate the supply response for Greek cereals in the 1961–1982 period. Particular attention is given to the impact of weather conditions and to technical progress by inclusion in the model of appropriate variables related to alternative concepts of technical progress. The calculated price elasticities suggest that Greek farmers are reasonably responsive to price changes, though the degree of responsiveness varies considerably from product to product. Some policy implications are drawn from the analysis, given EC and national cereal price policies.
