This article provides an analysis of the thoughts of an Italian academic who lived in the first half of the twentieth century, Lorenzo De Minico, in particular it regards his approach to the allocation of common costs. De Minico's main concern was with the conventional, subjective allocation methods proposed by Italian practitioners and academics of his time. He valiantly searched for a methodological approach based on using causality as the basis for linking costs to cost objects. The most interesting finding of De Minico was the concept of ‘flows of services’ and his commitment to offering a convincing answer to the problem of general or common cost apportionment that went beyond ‘traditional’ criteria. De Minico's ‘flows of services’ referred to the outputs of resources consumed in indirect services. These indirect costs can be considered easily ‘directly attributable’ only if it is possible to measure the connected ‘flows of services’. The article shows that the concept developed by De Minico in early twentieth century of Italy confirms the idea that some theoretical frameworks for a causal allocation of common costs were in existence many decades before information technology made such systems a practical proposition.
