Uno Kozo's analysis of this concept in terms of jittai, kettai, and honshitsu, or substance, form, and essence, is discussed in an Elena Louisa Lange book titled for it "without fetish." The "temporal single-system interpretation" aims to address the claim that a theory of this concept is unnecessary (-5[1])for explaining exploitation. Paul Sweezy popularized the problem of determining the rules by which inputs of this concept are converted into outputs, known as the (*) transformation problem.
