Estimating Farm Level Multivariate Yield Distribution Using Nonparametric Methods AgEcon
Zheng, Qiujie; Wang, H. Holly; Shi, Qinghua.
Modeling crop yield distributions has been an important topic in agricultural production and risk analysis, and nonparametric methods have gained attention for their flexibility in describing the shapes of yield density functions. In this article, we apply a nonparametric method to model joint yield distributions based on farm-level data for multiple crops, and also provide a way of simulation for univariate and bivariate distributions. The results show that the nonparametric models, both univariate and bivariate, are estimated quite well compared to the original samples, and the simulated empirical distributions also preserve the attributes of the original samples at a reasonable level. This article provides a feasible way of using multivariate...

Washington Biofuel Feedstock Supply under Price Uncertainty AgEcon
Zheng, Qiujie; Shumway, C. Richard.
Biofuels, as alternative transportation fuels, are now being used globally. Taking advantage of in-state feedstock supply is an efficient way to stimulate in-state biofuel industries and the local economy. This paper uses the mean-variance model of utility maximization to estimate supply equations for major biofuel feedstock crops in Washington. We consider price risk, examine the comparative statics results of the model, and use the results to draw important decision-making implications for Washington farmers who are considering production of biofuel feedstocks. Of three potential feedstock crops, only one shows immediate promise in Washington.
Tipo: Conference Paper or Presentation Palavras-chave: Biofuel feedstock; Price uncertainty; Supply; Crop Production/Industries; Production Economics; Risk and Uncertainty.
