Tourism sector is one of the important sectors for countries in terms increasing employment opportunities, providing income economy and raising foreign currency earnings. Employing 2002 2012 input-output tables, aim this study to assess tourism Turkey with model. According results obtained, related are slightly above average among all other multipliers, output multipliers forward - backward lin...

Intermediate goods are another produced factor of production, like capital. Simple examples suggest that the multiplier associated with intermediate goods can be substantial, even larger than the one resulting from physical capital accumulation. This paper evaluates this insight using a model in which N goods are produced using all of the other goods as intermediate inputs. Calibrating the mode...

This paper deals with phase gratings working in the paraxial domain. The profile of the optimum-efficiency beam multiplier with an arbitrary number of output diffraction orders is derived in an analytic form by exploiting methods from the calculus of variation. The output beams may be equi-intense or with arbitrary distribution of power. Numerical examples are given for different values of the ...
