Data: We use the 22 year long series of household income and expenditure data from the Household Budget Surveys of Polish households conducted by the official Statistics Poland in the years 1995-2016. During this period the sample of households increased from 25 to 37 thousand households surveyed per year. Altogether the data set used for this research consists of 650 thousand households.
Method: From the cross sectional data for Polish households we constructed 67 cohorts (defined by year of birth) of heads of households born in the years 1930-1996. We examine a persons ages 20-75 years during 1995-2016. Deaton decomposition was applied to decompose the household saving rate into cohort and age effects.
Results: The results of the cohort analysis show that the life cycle age effects for household saving are increasing with age and the cohort effects for household saving are increasing for younger cohorts. These results are not in full compliance with the life cycle theory but are representative for the fast growing emerging economies.
