Reflexiones en torno a las dinámicas de Domar y Harrod

In the type of keynesian analysis the productive capacity is a constant, and therefore the problems derived from obtaining an equilibrium between the global supply (offer) and the global demand, even when they may be difficult to solve, specially to obtain the best levels of occupation of the productive factors, once the solutions are obtained, Hill be permanent. In exchange, in the dynamic analysis of Domar and Harrod, the problem will be repeated constantly, due to the modification of the productive capacity of the system. The income and the investment, in the search for equilibrium, ought to increase permanently at a fixed rate, determined by the product of the propensity to save and the productivity of the capital. This will be the proportional growth. The same analysis can be applied to the problems of non proportional growth: cyclical and "secular". With reference to the later it can be suggestively observed that the problems of high development appear to be solutions of under development and vice-versa.Instituto de Investigaciones Económica
