general equilibrium models, with respect to the specification of capital and investment aggregation. They demonstrate that … (small) differences in the specification of capital and investment aggregation may yield large differences in the policy …

Dynamic multi-sector computable general equilibrium (CGE) models often utilize investment aggregation according to … investment shares by optimal household decisions in a framework with heterogeneous capital? Two models - a model with … heterogeneous capital, and a second model with a capital aggregate (and fixed investment shares) - show that the impact of the same …
