英文文献摘要：
This paper makes a contribution to the application of nonlinear simultaneous equations estimation and nonparametric Bootstrapping techniques. The nonlinear demand model estimation work in this paper is in the context of the newly developed Quadratic Almost Ideal Demand System (QUAIDS) model, and provides substantive results in terms of both model estimation technique and empirical economic findings. For the first time, bootstrapping is used in this highly nonlinear modeling environment to estimate variability in demand model parameter estimates and associated demand elasticities. The application relates to Japanese consumer behavior relative to Wagyu Beef, Imported Beef, Pork, Chicken, and Fish demand, and the empirical results are highly relevant to U.S. exporters. The paper provides evidence of the substantially increased flexibility of the new model of consumer demand, and also illustrates the utility of using bootstrapping, as opposed to relying only on derivative based asymptotic approximations, for assessing the reliability of estimated results.
本文对非线性联立方程估计和非参数自举技术的应用做出了贡献。本文的非线性需求模型估计工作是在新开发的二次近似理想需求系统(QUAIDS)模型的背景下进行的，并在模型估计技术和经验经济结果方面提供了实质性的结果。第一次，bootstrapping被用在这个高度非线性的建模环境中来估计需求模型参数估计的变异性和相关的需求弹性。该应用涉及日本消费者对和牛、进口牛肉、猪肉、鸡肉和鱼类需求的行为，实证结果与美国出口商高度相关。这篇论文提供了大量增加的灵活性的消费者需求的新模型的证据，也说明了使用bootstrapping的效用，而不是仅仅依靠基于渐近的导数来评估估计结果的可靠性。
