The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and tota...

The number of electricity consuming equipment for existing household end-user is continuing to increase, and some residential buildings already consume more energy than existing building regulations prescribe. The uprising SmartGrid technology with alternative energy sources could be a key to solve this problem, but it is demanding also for a “smarter” consumer with ability to monitor and manag...

The selection of the best suppliers is a key issue for many companies. Nevertheless, it is important to highlight that the most economical supplier may not be the one that has the lowest purchase price. The cheapest supplier is the one that represents the lowest cost to the company, after being considered various aspects of supplying, such as quality, reliability of deliveries, the history of s...

The starting point of this article is the result of one ultimatum game experiment one of many showing a huge deviation from the predictions of micro theory. However, further analysis gives an explanation of subject behavior that deserves to be seen as rational, if assumptions, such as a total secrecy resulting in no effects on reputation, are questioned. Respondersí actual behavior can be under...

A common sales tactic is for a seller to encourage a potential customer to make her purchase decision quickly. We consider a market with sequential consumer search in which firms often encourage first-time visitors to buy immediately, either by making an “exploding offer” (which permits no return once the consumer leaves) or by offering a “buy-now discount” (which makes the price paid for immed...

Purchasing and supply leaders continually search for ways to improve the quality, delivery, and cost of production inputs. Their participation in these proactive supply chain activities can be a significant driver of purchasing and supply management’s use of information technology (IT). Using a transaction cost analysis perspective, we surveyed purchasing and supply professionals at the directo...

Although set-up costs are prevalent and substantial in natural resource extraction, their analysis in decentralized markets is difficult. In particular, it is known that a Walrasian competitive equilibrium cannot exist in simple extraction models with set-up costs thus rendering standard competitive equilibrium analysis inapplicable. However, this paper demonstrates that this result is sensitiv...
