Abstract
We consider exogenously given firms and multi-member households operating in a competitive market environment. Households are endowed with resources (commodity bundles) and shares of firm ownership. Household members are characterized by individual preferences, possibly with intra-household consumption externalities. Household decisions adhere to the collective rationality model.
-
The existence of general equilibrium and the validity of the first welfare theorem are investigated.
-
We take a first pass at a general equilibrium model with multi-member households and production.
-
The existence proof relies on induced household preferences for aggregate household consumption, so that household choices and production plans reside in the same Euclidean space.
-
Equilibrium welfare is also addressed.

\(\parallel \!\cdot \! \parallel _d\) denotes the Euclidean norm on a d-dimensional Euclidean space. We use the notation \(\gg ,\,>\) and \(\ge \) for vector inequalities.

At the macro level, the value of household production is significant and could be around 35% of GDP in developed countries (see Apps and Rees (2009), p. 32).
