Bankruptcy is one of the most important entrepreneurial problems studied by the Financial Theory. Despite this great effort there is not a significant progress in order to predict the economic failure. In this way the evidence suggests that this problem related to the experimental design is still present because of two main reasons: ignorance about bankruptcy process and the use of the accounting information as the unique input to construct the predictive models. In order to solve those problems the RPV Model included both qualitative and accounting information with excellent results. So the Earning Power Theory –upon which the RPV is based– could cause problems of specification and structure in the model. Empirical results not only verify those suspicions but they made a stronger model possible by introducing to the equation ERC values adjusted to the risk.

The following paper analyses the sustainability of the Peruvian “Pay as You Go System” which is provided by the Government. In Peru, the “Pay as you Go System” coexists with Private Pension Funds or “Fully Funded Pension”. Sometimes both systems compete with each other with advantages and disadvantages between them. We found that “Pay as You Go System” cannot be sustainable over a long period of time. In addition, based on a comparative analysis of advantages and disadvantages, we propose some recommendations to make Private Pension Funds (Fully Funded Pension) the best alternative to Pay as You Go System.
