Abstract In 2014, many innovations were introduced in the Italian Household Budget Survey (HBS) in response to changes in European recommendations and purchasing behaviours and to an increased demand for information in the context of social and economic research. New instruments and techniques have been introduced, together with more accurate methodologies, with the aim of improving the survey, by both reducing the bias and variance of survey estimates and supplying estimation for additional subpopulations and variables. Given the parallel conduction of the former and new HBS in 2013, it has been possible to evaluate the effects of the abovementioned changes on consumption expenditure and inequality estimates and to compare the sample representativeness of selected subpopulations in both surveys.

调查家庭预算调查重新设计对消费和不平等估计的影响：意大利的经验

摘要在2014年，意大利的家庭预算调查（HBS）中引入了许多创新，以响应欧洲建议和购买行为的变化以及在社会和经济研究背景下对信息的需求增加。引入了新的工具和技术以及更准确的方法，以期通过减少调查估计的偏差和方差以及为其他子群体和变量提供估计来改进调查。考虑到2013年以前的HBS与新的HBS平行进行，有可能评估上述变化对消费支出和不平等估计的影响，并在两次调查中比较选定亚人群的样本代表性。
