We test for the presence of "rule of thumb" consumers as originally proposed by Cambell and Mankiw (1991), using sentiment measures distinguished by working condition of the household. Consumption data are disaggregated according to durability. The role of sentiment results to be stronger for service expenditures. Psychological motives of employees are found to have a particularly significant influence on consumption decisions. Moreover, CSI can not be explained by economic fundamentals alone, capturing also the effects of the political cycle and exceptional circumstances.
