RIGIDECES Y PLENO EMPLEO

Abstract

It is axiomatically shown in this paper that neoclassical theory does not admit any possibility of disequilibrium. If agents while calculating their supply and demand plans take into account the stickiness in the prices vector, the effect of it is annulled, and the economy -eventually not competitive due to the stickinessfunctions as if it was competitive at all. Full employment equilibrium becomes a result even under sticky wages, which implies that in the neoclassical framework it is not possible to explain involuntary unemployment, not even under the assumption of exogenous stickiness.En este documento se demuestra axiomáticamente que la teoría neoclásica no admite la posibilidad de desequilibrios. Si los agentes, al calcular sus planes de oferta y demanda toman en cuenta las distorsiones en el vector de precios, el efecto de éstas se anula, y la economía –eventualmente no competitiva a causa de las distorsiones- funciona como si fuese competitiva. El equilibrio de pleno empleo se garantiza aún con rigideces, lo que implica que en el marco neoclásico no es posible explicar el desempleo involuntario, ni siquiera suponiendo rigideces exógenas.&nbsp
