Konsumentprisindex för ett stratum
This paper uses a survey to estimate the proportion a unionized painter spends on different product cathegories. The result is used together with data from SCB (Statistics Sweden) to estimate a consumer price index for this group. The estimated value for the unionized painters is later compared with the official value SCB calculates. The paper shows that the unionized painters had a 0.38 percentage points higher inflation than the official value which SCB calculated in 2021. The main causes for this are that painters as a group spends more money on accommodation, transport and food compared to the national mean. These product cathegories have had relatively high price increase in 2021. The paper also shows that the painters that use their private car at work are making a loss in doing so.
