Different structures of lignite mines and power stations, which have appeared on the Polish market as a result of its transformation and the privatisation, were discussed. The attention is focused on the fact that the practice is overtaking the theory because there is lack of models of...

For methods of the profit division in the bilateral monopoly of the mine and the power station sug-gested in the first part of this paper the formulae for lignite price and shares in the joint profit of the mine and the power station are calculated. The proposed profit division contain: the...

The Deepwater Horizon incident demonstrated that most of the oil left is deep offshore or in other difficult to reach locations. Moreover, obtaining the oil remaining in currently producing reservoirs requires additional equipment and technology that comes at a higher price in both capital and...

Two oil price shocks changed the pattern of cheap oil. The first was the Arab embargo on oil exports in 1973. Oil prices rose five fold. In 1978, the second was the fall of Shah Iran. Prices soared to $80-$100 a barrel in today‘s prices. In 1960, OPEC was established and since then it has been...

We present a growth model in which a non-renewable resource enters in the production function. The non-renewable resource is supposed to be sold by an external monopolistic that maximizes his intertemporal discounted cash flow. This approach allows to endogenize the price of the resource. We use...

For the hypothetical deposit with parameters similar to KWB “Konin” S.A. conditions; lignite prices and proposed divisions are calculated and results were discussed under the angle of the fairness (equity) of the division and the possibility of their approval by both sides. A sensitivity...

This paper provides a few general comments on the nature and economic value of industrial minerals and rocks and the need for an increased exploitation and use of these materials in developing countries. These materials are of great economic value as main raw materials for the construction,...

There is a disagreement on the concept, definition and application of the paradigm of sustainable development. The definition that has been accepted by many involves several components, and it is difficult to measure or quantify indicators. Depending on the structure of the economy, it is...

Lignite mine and power plant can operate as two separate entities, two entities in one holding or joint venture and as the one vertically integrated energy producer. Each of these solutions has the influence on operation of this tandem including realization of its individual and joint...

The newest outcome of bilateral monopoly (BM) of lignite opencast mine & power plant analysis have been discussed. The determinism of optimal solution maximising joint profits not only in quantity of lignite - the size and shape of the ultimate pit (characteristic to classical solution) but also...
