Aggregation rules across 3 different households

General DSGE Modeling
1

Dear all,

I just wanted to know if the standard aggregation rule for Ricardian vs Non-Ricardian households used in DSGE models could also apply to 3 households?

Aggregate consumption = share of household 1 * C_1 + share of household 2 * C_2 + (1- share household 1 - share household 2) * C_3

When I do that and resolve my problem, Dynare give me odd results for one household. The household with the highest share (65%) in the economy has the lowest total consumption which is odd.

Thanks

Hi dacorb

I reckon this is the correct way to aggregate. Regarding the per capita values in steady state, it is difficult to tell without seeing the model.

Yes, you need to weight with the share of households. Why do find it strange that

Thank you both.

Actually, all is good ! It was just a rescaling problem.

Wishing you a good day ahead.
