DSGE · Subgroup

Heterogeneous households

Household heterogeneity layered onto the New Keynesian core -- TANK introduces hand-to-mouth households alongside Ricardian savers, and HANK-lite carries the heterogeneity further while keeping the structure tractable.

What this subgroup is

The heterogeneous households lane in the DSGE family

Household heterogeneity layered onto the New Keynesian core -- TANK introduces hand-to-mouth households alongside Ricardian savers, and HANK-lite carries the heterogeneity further while keeping the structure tractable.

Reference/Structure reference

When to use it

When to reach for heterogeneous households

Reach for the heterogeneous-household routes when the question is about how policy or shocks land differently across household types -- fiscal multipliers, redistribution, or the marginal propensity to consume.

Routes currently covered

Heterogeneous households routes

Each route below is a DSGE model reference page with overview, graph, proof, and comparison material.

Heterogeneous householdsReference/Structure reference

TANK

Two-agent New Keynesian structure that separates hand-to-mouth from asset-holding households.

HANK-lite

A lighter heterogeneous-agent structural route that keeps liquid and illiquid balance-sheet channels visible.

Coverage for this subgroup

2 routes linked in this subgroup's DSGE reference coverage.

Currently covers two routes: TANK (two-agent NK) and HANK-lite. The structural reference pages document the household-heterogeneity variants.

How this subgroup differs

How heterogeneous households sits next to other DSGE subgroups

Heterogeneous households is grouped separately from sticky-price core, financial frictions because the structural assumptions, frictions, or household structure are meaningfully different, not because the models are unrelated. The cross-links below let you hop sideways without losing the DSGE frame.
