Fuzzy logic, parity theories and two currencies valuation for emerging markets with de discount cash flow model

The discount cash flow model must incorporate, in emerging economic systems, a conceptual framework for the inflation and valuation in two currencies treatment. The start point are the parity theories and Fisher effect, adding fuzzy logic for project uncertainty variables: interest rates, inflation, exchange rates and quantities, becoming one of its main contributions. The structure of the paper as follows: they are developed the parity theories and model´s equation at the fuzzy logic framework. Its functioning is illustrated with case of a firm located in an emerging and inflationary economy like Argentina, using spreadsheets. Finally, the results obtained showed the consistency with the parity theories, adding fuzzy logic for the uncertainty treatment, at the comprehensive framework of discounted cash flow model in two currencies.
