Use of efficiency measures as a proxy for performance to test the market structureconduct-performance (SCP) hypothesis is explored. Utilizing Battese and Coelli specification, we estimate stochastic frontier production function and SCP equations with output and efficiency measures as endogenous variables. An empirical application to U.S. trucking carries over the period 1994-2003 with emphasis ...

there are many approaches in economic literature for investigation of firm performance. in general, those theories very useful for investigation the nature and role of competitive advantage. resource based view, dynamic capability, entrepreneurial theory, neoclassic theory, industrial organization approach are some of those theories. todays, banks try to attract customers through various new me...

OBJECTIVES Communication support for severely paralyzed patients with visual impairment is needed. Therefore, the feasibility of a brain-computer interface (BCI) using auditory stimuli alone, based on the self-regulation of slow cortical potentials (SCPs), was investigated. METHODS Auditory stimuli were used for task and feedback presentation in an SCP self-regulation paradigm. Voluntarily pr...

The habituation paradigm has been applied to study the development of memory, perception, and other cognitive processes in preverbal infants, making it one most prominent experimental paradigms infant research. However, there are many features process that remain elusive, which results uncertainty about best research practices. This article first discusses current practices (e.g., use criteria)...

Two groups of subjects, aged 20-28 and 50-64, respectively, matched for health status and verbal abilities, learned to control their slow cortical potentials (SCP) in a feedback paradigm by producing, on command, SCP shifts in either positive or negative direction. Both groups were able to differentiate significantly between the positivity task and the negativity task, with the differentiation ...

We perform error probability analysis of the uncoded OFDM fixed gain Amplify-and-Forward (AF) relaying system with subcarrier permutation (SCP). Two SCP schemes, named: the best-to-best SCP (BTB SCP) and the best-to-worst SCP (BTW SCP) are considered. Closedform expressions for the bit error rate (BER) of the above SCP methods are derived. Numerical results manifest that these SCP schemes may o...

the present study surveys the effect of bank-specific, industry-specific and macroeconomic conditions on bank performance to examine the structure-conduct-performance (scp) hypothesis in iranian banking industry. to achieve this goal, we drew upon the panel data technique to analyze the data of eleven public and private iranian banks during 2001-2006. firstly, productivity was calculated by usi...

Structure, Conduct and Performance (SCP) is used as an analytical framework, to make relations amongst market structure, market conduct and market performance. The objective of this study was to analyze the factors, which affect SCP of livestock markets in the Butana area, Sudan in 2011. A total sample of 222 livestock traders were surveyed using structured questionnaire in seven primary and se...
