The “Triple Depreciation Line” Accounting Model and Its Application to the Human Capital

Abstract Purpose This chapter gives in “Introduction to the Human Capital Issue” a critical analysis of the standard (economic) Human Capital (HC) theory, with the help of some “traditional” (founding) accounting concepts. From this study, to avoid the accounting and social issues highlighted in “Introduction to the Human Capital Issue,” we present, in “The “Triple Depreciation Line” Model and the Human Capital,” the “Triple Depreciation Line” (TDL) accounting model, developed by Rambaud & Richard (2015b), and we apply it to “HC,” but viewed as genuine accounting capital – a matter of concern – that firms have to protect and maintain. Methodology/approach From a critical review of literature on HC theory, from the origin of this concept to its connection with sustainable development, this chapter provides a conceptual discussion on this notion and on the differences/common points between capital and assets in accounting and economics. Then, it uses a normative accounting model (TDL), initially introduced to extend, in a consistent way, financial accounting to extra-financial issues. Findings This analysis shows at first that the standard (economic) HC theory is based on a (deliberate) confusion between assets and capital, in line with a standard economic perspective on capital. Therefore, this particular viewpoint implies: an accounting issue for reporting HC, because “traditional” accounting capital and assets are clearly isolated concepts; and a societal issue, because this confusion leads to the idea that HC does not mean that human beings are “capital” (i.e., essential), or have to be maintained, even protected, for themselves. It only means that human beings are mere productive means. The application of the TDL model to an accounting redefinition of HC allows a discussion about some key issues involved in the notion of HC, including the difference between the standard and “accounting” narratives on HC. Finally, this chapter presents some important consequences of this accounting model for HC: the disappearance of the concept of wage and the possibility of reporting repeated (or continuous) use of HC directly in the balance sheet. Research implications This chapter contributes to the literature on HC and in general on capital and assets, by stressing in particular some confusions and misunderstandings in these concepts. It fosters a cross-disciplinary approach of these issues, through economic, accounting, and sustainability viewpoints. This analysis a
