We contribute to the task of identifying trends and cycles in energy prices by examining very long series of prices for coal and oil, going back to 1650 in the case of coal and 1859 in the case of oil. We find annual rates of increase in real price of greater than two percent are found for coal...

The application of Nash bargaining solution to profit division in negotiation between opencast lignite mine and power plant has been discussed. Different proposals of status quo point usage and ways of its determination for profit sharing both in strategic and tactical/operational negotiation...

Oil and gas company returns are compared between upstream, midstream, and down-stream sectors from 2000 through 2020. Crude oil, natural gas, and distillate returns reflect project risk, infrastructure, and conditions within the industry. Equity, commodity, and distillate markets positively...

Regression model error assumptions are essential to estimator properties. Least squares model parameters are consistent and efficient when the underlying error terms are normally distributed but yield inefficient estimators when errors are not normally distributed. Partially adaptive and...

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...

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 US and UK markets for natural gas are connected by arbitrage activity in the form of shifting trade volumes of liquefied natural gas (LNG). We empirically investigate the degree of integration between the US and the UK gas markets by using a threshold cointegration approach that is in...

The issue of security of gas supplies is frequently discussed on the basis of intuitive and non-systematic arguments. Greater import dependence is normally equated with greater insecurity, and strategic stocks are the risk management tool most commonly considered. This paper strives to offer a...
