The paper proposes a combination of two methods: the Net Present Value Method and the Earned Value Method – to control the risk of not achieving the targeted value of long-term projects. The method is capable, like the Earned Value Method, to forecast future financial overruns ahead of time...

By applying copulas the examination was carried out to find out whether trading volume, stock return and return volatility are pairwise dependent. In the investigations it was shown that there exists a close relationship between these variables on the domestic market and between Polish stock...

In standard input-oriented DEA it is assumed that the marginal productivity of inputs is constant. The efficiency changes can be achieved by proportional changes of all inputs. The author of the article considers decreasing marginal productivity of inputs and presents the appropriate...

In the paper electricity load analysis was performed for a power region in Poland. Identifying the factors that influence the electricity demand and determining the nature of the influence is a crucial element of an effective energy management. In order to analyse the electricity load level the...

In the paper we discuss the problem of selecting one investment project from a set containing several projects in the situation when their parameters (above all the cash flows) are still unknown exactly. In such a situation the choice of one project is not unequivocal. While taking similar...

The author suggests a “model” of relations between liquidity, costs of liquidity and basic or empirical profitability. The first part of the article present the idea of the model analysis. The author makes an effort to explain the frequent empirical paradox – when an increase of liquidity...

In order to check out the significance of errors in the estimation of capital cost in investment appraisal, the simulation experiment has been presented in the paper. On the basis of the simulated development of the comparable firms, we have compared the end values of two simulated companies....
