in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...

This paper analyzes the output]energy relationship with alternative measures of output and energy. Our analysis rejects the hypothesis of non-diminishing returns to energy consumption when GDP at purchasing power parities is used as the output measure unlike the case with GNP at market exchange rates. This finding also holds when energy input includes the usage of both commercial and traditiona...

this paper explores the importance of oil sector in providing input for economic sectors and also its changes during the last decades in iran. to that end, the partial and total forward linkage between oil sector and other domestic production sectors as well as their changes are examined using the input-output tables of the years 1986 and 2001. and also based on the information on hand, perform...

In the context of transition analysis, linear input-output analysis determines worst-case disturbances to a laminar base flow based on generic right-hand-side volumetric/boundary forcing term. The is not physically realizable, and, our knowledge, framework for posing physically-realizable disturbance problems lacking. natural receptivity are forced by matching (typically local) solutions within...

in this research، job opportunities have been examined among 26 productive sectors of iran's economy by using input-output table in 2001.from viewpoint of employment ،production and value added، the key sectors has been diagnosed by using mri ، elasticity of input-output table، backward and forward linkages and june's corrective methods. then، job opportunities has been analyzed among...

IN T R O D U C T IO N It is my opinion that the success or failure of our street operations can be measured in two ways. First is the effect on operations, which can be checked by travel time or delay studies at particular intersections. The second method is the use of accident data. Examples of actual findings of traffic improvement needs, developed directly from accident report analysis, have...

In fisheries, capacity analysis has largely been limited to measuring physical capacity, defined as the maximum amount of output that can be produced per unit of time, given existing plant and equipment and unrestricted availability of variable inputs. An economic measure of capacity can be defined as the maximum revenue attainable for the given fixed inputs, using relevant outputs and output p...
