摘要

使用随机效用一致离散连续模型，我们分析了澳大利亚农民样本对除草剂组合及其使用强度的决策。所提出的模型是灵活的，甚至可以适应关于单一除草剂的决策。我们使用基于序列二次规划的预测方法来预测最佳除草剂类型和分配。结构估计用于预测价格变化如何影响除草剂需求。预测方法允许校准替代特定常数，以再现现有品牌市场份额。

Multiple Herbicide Use in Cropland: A Discrete-Continuous Model for Stated Choice Data

Using a random utility consistent discrete-continuous model, we analyze decisions by a sample of Australian farmers on the mix of herbicides and their intensity of use. The proposed model is flexible and even accommodates decisions concerning a single herbicide. We use a sequential quadratic programming-based forecasting approach to predict optimal herbicide types and allocations. Structural estimates are used to forecast how price changes affect herbicide demand. The forecasting approach allows for calibration of alternative specific constants to reproduce existing brand market shares.

期刊介绍： Land Economics is dedicated to the study of land use, natural resources, public utilities, housing, and urban land issues. Established in 1925 by the renowned economist and founder of the American Economic Association, Richard T. Ely at the University of Wisconsin, Land Economics has consistently published innovative, conceptual, and empirical research of direct relevance to economists. Each issue brings the latest results in international applied research on such topics as transportation, energy, urban and rural land use, housing, environmental quality, public utilities, and natural resources.
