Abstract

We prove the existence of competitive equilibrium in the canonical optimal growth
model with elastic labor supply under general conditions. In this model, strong
conditions to rule out corner solutions are often not well justied. We show using
a separation argument that there exist Lagrange multipliers that can be viewed
as a system of competitive prices. Neither Inada conditions, nor strict concavity,
nor homogeneity, nor dierentiability are required for existence of a competitive
equilibrium. Thus, we cover important specications used in the macroeconomics
literature for which existence of a competitive equilibrium is not well understood.
We give examples to illustrate the violation of the conditions used in earlier existence
results but where a competitive equilibrium can be shown to exist following the
approach in this paper.
