Fertilizer demand in Greece
使用希腊数据，通过误差修正模型和协整技术估计化肥需求的短期和长期价格弹性，发现减少农业支持可能比提高化肥价格更有效降低化肥使用量。
Abstract Limiting fertilizer use is becoming an important policy objective world‐wide. However, the debate on appropriate policy measures is far from settled and evidence on fertilizer demand elasticities is still insufficient. Past studies on fertilizer demand leave several methodological and empirical issues open. This paper aims to contribute to the debate on the methodology of estimating fertilizer demand using single‐equation methods. Dynamic aspects are also considered using error‐correction modelling methodology and cointegration techniques. The model is applied using data front Greece. Short‐run and long‐run price elasticities of fertilizer demand with respect to own price and to output prices show significant response to price changes and the adjustment coefficient of fertilizer use to the error‐correction term was found to be fairly rapid. The main policy conclusion of the paper is that reducing agricultural support may be an alternative and, perhaps, more effective way of reducing fertilizer demand than increasing fertilizer prices.
