英文摘要：
  Most papers which explored so far macroeconomic variables took into account income and wealth. Equally important as the previous macroeconomic variables is the expenditure or consumption, which shows the amount of goods and services that a person or a household purchased. Using statistical distributions from Physics, such as Fermi-Dirac and polynomial distributions, we try to fit the data regarding the expenditure distribution divided in deciles of population according to their income (gross and disposable expenditure are taken into account). Using coefficient of determination as theoretical tool in order to assess the degree of success for these distributions, we find that both distributions are really robust in describing the expenditure distribution, regardless the data set or the methodology used to calculate the expenditure values for the deciles of income. This is the first paper to our knowledge which tackles expenditure, especially using a method to describe expenditure such as lower limit on expenditure. This is also relevant since it allows the approach of macroeconomic systems using more variables characterizing their activity, can help in the investigation of living standards and inequality, and points to more theoretical explorations which can be very useful for the Economics and business practice.

中文摘要：
迄今为止，大多数探讨宏观经济变量的论文都考虑了收入和财富。与之前的宏观经济变量同样重要的是支出或消费，它显示了一个人或一个家庭购买的商品和服务的数量。利用物理学中的统计分布，如费米-狄拉克分布和多项式分布，我们试图拟合按收入（总支出和可支配支出）划分为十分之一人口的支出分布数据。使用确定系数作为理论工具来评估这些分布的成功程度，我们发现，无论用于计算收入十分之一的支出值的数据集或方法如何，这两种分布在描述支出分布方面都非常稳健。据我们所知，这是第一篇涉及支出的论文，尤其是使用一种方法来描述支出，如支出下限。这也是相关的，因为它允许宏观经济系统使用更多的变量表征其活动，有助于调查生活水平和不平等，并指出更多的理论探索，这对经济学和商业实践非常有用。
