“…With regard to the neoclassical case, at the aggregate level, Ca / la = Cc / lc As capital is valued in quantities of corn, these quantities do not depend on the variation of w and r, and Ca / la = Cc / lc for any value of r and w In other words, there is an equivalence between quantities and values (Herscovici, 2019) The implications are as follows: when capital is heterogeneous, it is no longer possible to reason in terms of the quantities of capital It is necessary to express this amount of capital in a common unit, that is, in value In this case, the value of a given quantity of capital varies depending on the variation of w and r; now, the variations of r and w determine the C / l ratios The Ricardian differential rent theory highlights the need to reevaluate capital in each period, when it is heterogeneous (Herscovici, 2019) When capital is heterogeneous, it is not possible anymore to verify Ca / La = Cc / Lc, for values of r greater than 0 In other words, the Ca / La = Cc / Lc ratio will only be verifi ed, for all positive values of r, if the economy produces a single good This mechanism highlights the explanatory limits of the theories based on this hypothesis 8…”
