This article presents a comprehensive values and prices formation model based on Marx’s (1992, 1993) labor theory of value within a Temporal Single-System Interpretation (TSSI) framework. This model bases on a new interpretation of the Marxian Fundamental Theorem (FMT) and the Monetary Expression of Labor Time (MELT). If the modification in the dialectical sequence of the formation of the categories and the introduction of the dual determination of socially necessary labor time are accepted, the transformation problem encounters solution in the interpretation of Carchedi and de Haan (1996). Likewise, contemporary approaches reveal the need for a redefinition of key categories of the Marxist labor theory of value to develop a logically coherent model. Thus, the proposed model includes the dimension of the realization problem that commodities face in the market and introduce analytical categories for both production and realization periods. Finally, value category is redefined.
