本文的目的是提出一个贝叶斯方法估计系统的恩格尔函数使用调查数据，包括零支出。我们明确地处理零支出的问题，在模型中，并估计一个系统的恩格尔函数，满足加法条件。此外，我们使用马尔可夫链蒙特卡罗方法，估计不可观测的参数，包括商品的消费，总消费和等价规模，并使用其后验分布计算不等式的措施和总消费弹性。
The objective of this article is to propose a Bayesian method for estimating a system of Engel functions using survey data that include zero expenditures. We deal explicitly with the problem of zero expenditures in the model and estimate a system of Engel functions that satisfy the adding-up condition. Furthermore, using Markov chain Monte Carlo method, we estimate unobservable parameters, including consumption of commodities, total consumption and equivalence scale, and use their posterior distributions to calculate inequality measures and total consumption elasticities.
