• Its geographical market definition accounts only for a factor that is no longer relevant and for none of the factors that matter in a competitive market. • Its use of uncommitted-shares registers more market power when the market itself is more competitive and less market power when it is less competitive. Thus it often reads in reverse the impact of the market on the applicant. • It takes no...

Distributed computing environments place more computer power in the hands of the end-user, and often demand increased technical support. In response, organizations may choose to move technical support personnel close to end-users. This can isolate them from each other, and may limit their ability to share knowledge. Thus, the growth of distributed computing calls for increased ability to share ...

date is as one of the important items of the agricultural production in iran as iran's share of global production was 14.1% in 2012 and rank of production increased to second in the world too. in recent years, price uncertainty in date market has increased due to changes in government policies on date prices pattern, from a guaranteed buying pattern to negotiated price pattern. according to the...

in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...

Market power assessment is a prime concern when designing a deregulated electricity market. In this paper, we propose a new functional market power measure, termed transmission constrained network flow TCNF , that takes into account an AC model of the network. The measure unifies three large classes of long-term transmission constrained market power indices in the literature: residual supply ba...

It is difficult to eliminate all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery, facilitate investment, and increase security of supply. This suggestion implicitly assumes all generation technologies benefit equally from market power. We assess a mixture of conventional and...

The consequences of the liberalisation electricity markets have been widely discussed in literature emphasising successes or failures privatisation and deregulation. While most developed power systems undergone a form economic transformation, they still require to be monitored analysed assess market power. Polish system is an example wherein potential examined fifteen years ago was summarised a...

the impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. in this study, asymmetric tea market is investigated through an application of johansen co-integration analysis and error correction model (ecm model) to time series of 1976-2009. co integration method used in the import mark...
