When Marx's theory is understood in accordance with the TSSI, rather than in accordance with Bortkiewicz's interpretation, moreover, the results of his transformation account re-emerge as internally consistent; price and value magnitudes are indeed equal in the aggregate. These equalities also re-emerge under other––atemporal––single-system interpretations. Yet under the atemporal interpretations, Marx's falling-rate-of-profit theory and other aspects of his value theory still appear to be internally inconsistent. In order for his theories to be fully acquitted of charges of inconsistency and error, he must be interpreted as having had a temporal conception of value and price determination.
