The reswitching issue remains in the background of these studies as a remote albeit ever-present possibility. The article contributes some more evidence to the extant literature by utilizing data from the last available benchmark input-output table of the US economy of the year 2012. The derived near-linearities of price trajectories and wage-rate of profit curves are explained by the low effective rank of the economy&#8217;s input-output matrices and not from their seemingly random character. These findings shed additional light on a new and more meaningful direction in the research agenda, the possibility of molding the essential features of the economy through dimensionality reduction.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN En años recientes, la investigación sobre la teoría del capital se ha desplazado de la profundización inversa de capital y el recambio en las técnicas hacia una nueva dirección que va más allá de las cuasi-linealidades de las trayectorias de los precios-tasas de ganancia y de las curvas de salarios-tasas de ganancia y explica las razones que subyacen a esta clase de cuasi-linealidades. La cuestión del recambio subsiste en los antecedentes de estos estudios como una remota posibilidad, aunque siempre presente. Este artículo contribuye con alguna evidencia adicional a la literatura existente al utilizar datos de la más reciente tabla de insumo-producto estándar de la economía de Estados Unidos del 2012. Las cuasi-linealidades derivadas de las trayectorias de precios y de las curvas de salario-tasa de ganancia se explican por el nivel o posición efectiva baja las matrices de insumo-producto de la economía y no por su carácter aparentemente aleatorio. Estos hallazgos proporcionan luz adicional sobre una nueva y más significativa dirección en la agenda de investigación, la posibilidad de moldear las características esenciales de la economía a través de la reducción de dimensionalidad.]]></p></abstract>
