The paper presents the concept of the stochastic equivalence scale (SES), which is based on the stochastic indifference criterion. The SES is any function that transforms the expenditure distribution of a specific group of households in such a way that the resulting distribution is stochastically indifferent from the expenditure distribution of a reference group of households. The stochastic indifference criteria are also used in developing the method of the estimation of the SES. Non-parametric and parametric SESs are estimated using the Polish Household Budget Survey for the years 2005–2010.
