The paper presents a DSGE model (type: KANK) that allows using information on the heterogeneity of households, sectors and regions. We demonstrate how this model can be used for the purposes of regional macroeconomic analysis aimed at supporting the decision on monetary policy. The model is estimated using the Bayesian method on aggregated series of Russia, the Volga-Vyatka macroregion and foreign economy for the period 2014-2025. We demonstrate that in the presented version of the model, the role of shocks responsible for explaining heterogeneity is small. The contribution of such shocks to the dynamics of aggregated macroeconomic variables does not exceed 5%.
