文章研究了与消费者福利评估波动有关的各个方面：1．评估变化的幅度取决于所假定的错误来源；2．福利评估的准确性通常随着福利变化幅度的增加而下降；：3．马歇尔和希克斯福利评估的差异取决于所假定的错误来源，而且与标准错误相比可能是很小的。用线性需求函数和半对数需求
The article studies various aspects related to fluctuations in consumer welfare assessments: 1. Assessing the magnitude of the change depends on the assumed source of the error; 2. The accuracy of welfare assessments usually declines as the rate of change of benefits changes; The differences between Marshall and Hicks Welfare assessments depend on the sources of error assumed and may be small compared to standard errors. Use linear demand function and semi-logarithmic demand
