Abstract
Este trabajo tiene como objetivo una evaluación crítica y constructiva de algunas extensiones del análisis de Keynes de la demanda efectiva a largo plazo y el crecimiento. La crítica se dirige a una interpretación causal única en los modelos de crecimiento de la demanda y de la noción de utilización de la capacidad normal en tales modelos adoptados. Un argumento positivo intenta encontrar una caracterización distintiva de dichas ampliaciones en los términos productivos y financieros que hacen efectivos los cambios autónomos de la demanda agregada. Esto sugiere una noción de utilización de la capacidad normal como un rango de distribuciones de la de utilización normal, en relación con la elección de minimización de costes técnicos y de la persistencia de las expectativas de largo plazo de los precios normales subyacente en las decisiones de inversión. En tal contexto, el análisis de largo plazo con precios normales debería evitar un doble crecimiento estable, donde los precios relativos constantes de los bienes de capital se corresponden con las proporciones constantes entre sus existencias totales.
Abstract
This
paper aims at a critical and constructive assessment of some extensions
of Keynes’s analysis of effective demand to the long period and growth.
A criticism is addressed to a single-cause interpretation of the
demand-led growth models and to the notion of normal capacity
utilization adopted in such models. A positive argument tries to find a
distinctive characterization of those extensions in the productive and
financial conditions that make effective the autonomous changes in
aggregate demand. It suggests a notion of normal capacity utilization as
a range of distributions of normal utilization, related to the cost
minimizing choice of techniques and to the persistence of the long term
expectations of normal prices underlying the investment decisions. In
such a context a long-period analysis with normal prices should avoid a
dual steady growth where constant relative prices of capital goods
correspond to constant proportions among their total stocks.
