An otherwise conventional Keynesian macro model is modified to include inventories of final goods by (1) drawing a distinction between production and final sales, and (2) allowing for a negative effect of the level of inventories on production. Two models are presented: one in which the labor...

This paper presents a simple general equilibrium model in which the only non-Walrasian feature is imperfect competition in the goods market. The model is shown to exhibit various Keynesian characteristics. In particular, as competition in the goods market becomes less perfect, the fiscal policy...
