En el artículo se consideran las crisis económicas o recesiones, en general, como mecanismos propios del capitalismo para aliviar sus contradicciones y restablecer, al menos, parcialmente, los desequilibrios precedentes acumulados. El período 1970 a 2020 abarca ocho crisis económicas, algunas determinan cambios en la estructura interna, las tendencias de política económica y el funcionamiento de la economía estadounidense, como principal centro de la economía mundial. El propósito de este trabajo es examinar el conjunto de las crisis económicas de los últimos cincuenta años de manera panorámica, para evaluarlas como parte del proceso de las principales transformaciones económicas y políticas económicas asociadas.]]></p></abstract>
