Returns on the Capital Market: A Challenge for Investment

At the end of 2016, only the deposits in RON of households exceeded 103 billion RON, and those of nonfinancial companies exceeded 73 billion RON; this is why we consider that the approach of the return of investments on the capital market, as an alternative to investments on the monetary market, is a highly actual issue. In order to ensure the relevance of our approach, we have calculated and interpreted total return for the seven companies in the energy sector corresponding to the BET index (TGN, TEL, COTE, SNG, SNP, SNN, EL). In conclusion, the action of two “vectors,” i.e., low financial education and the fear of risk, is obvious in terms of both population and companies (seen not as an abstract notion but as entities managed by decision markers). For these reasons, many Romanian citizens and companies choose bank deposits as a way of investment money. This is why, in this context, we can talk of poverty generated by the fear of taking risks. It is very clear that, in order to achieve higher profitability, the risk one has to take is also higher.

Mathematical Modeling of Human Capital Evolution at Micro and Macroeconomic Level

Knowledge of human potential and especially labor resources implies a system of indicators, a quantitative and qualitative analysis that is complex and truthful at all levels. Human resources are changing in size and features in an organization. We intend to represent the human resources of an organization and the changes they undergo by using mathematical modeling, differential equations and even default probabilities.
