RESUMO: Este trabalho discute os requisitos teóricos para o ajustamento da capacidade produtiva à tendência da demanda, no contexto do modelo do supermultiplicador sraffiano, por meio de sua controvérsia na literatura, que girou basicamente em torno da hipótese de acelerador rígido. Para alguns isso implicaria em contínua plena utilização da capacidade, requerendo que a demanda se ajustasse à capacidade. Para outros, implicaria em excessiva sensibilidade do investimento à demanda, gerando instabilidade. Desenvolvimentos recentes, no entanto, confirmam que não há suposição de acelerador rígido, sendo o modelo plenamente compatível com o acelerador flexível e atendendo às condições de crescimento liderado pela demanda.
ABSTRACT: This paper discusses the theoretical requirements for the adjustment of productive capacity to demand, in the context of the controversy about the Sraffian supermultiplier growth model, that revolved basically around the assumption of a rigid accelerator. To some, this assumption would imply in the continuous full utilization of capacity, requiring demand to adjust to capacity. To others, it implied excessive sensitivity of investment to demand and instability. Recent developments, however, confirm that no assumption of a rigid accelerator is made, the model being fully compatible with a flexible accelerator and all the conditions required for demand-led growth.
