We study general discrete-types multidimensional screening without any noticeable restrictions on valuations, using instead epsilon-relaxation of the incentive-compatibility constraints. Any active (becoming equality) constraint can be perceived as "envy" arc from one type to another, so the set...

The newest findings in analysis of bilateral monopoly (BM) of lignite opencast mine & power plant have been discussed. The determinism of optimal solution not only in quantity of lignite (the size and shape of the ultimate pit) but also in its price has been depicted. It has been proposed to...

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...
