In the article possibilities of using econometric models to obtain propensities were discussed. Propensity to consumption of households containing pensioners and retired people in Poland in the years 1993-2004 was computed by means of the Gibbs sampling. Normal distribution was chosen as 'a priori' distribution of vector of parameter's estimates. Gamma distribution was set as 'a priori' distribution of parameter of precision. It was assumed that these 'a priori' distributions are independent. Empirical results showed that average propensity to consumption of households of pensioners and retired people in analyzed period was high (0,965)
