Consumer sentiment: its causes and effects
研究发现消费者情绪调查反映的态度对家庭耐用品购买有显著影响，尤其在重大经济或政治事件（如海湾战争）期间，情绪会独立于当前经济状况变动，为预测未来消费支出提供额外信息。
This paper finds that consumer attitudes, as reflected in surveys of consumer sentiment, have a significant influence on household purchases of durable goods. Normally, consumer sentiment moves with current economic conditions and bears a stable relationship to a few economic variables. At times of a major economic or political event like the Gulf War, however, consumer sentiment can move independently from current economic conditions. At such times it provides useful information about future consumer expenditures that is not otherwise available.
