3.2 Ghosh Supply-Side Assessment Methods for Infrastructure
The Ghosh Supply-Side model measures the changes in availability of inputs on industrial output. While the Leontief matrix relies on technical coefficients aij , the Ghosh matrix relies on allocation coefficients bij = zij / xi . The allocation coefficient measures the value of transactions from sectors i to j divided by the output of sector i.
\ The allocation coefficients can be made into a matrix B similar to A, as detailed in equation (13).
\
\ Thus, as per equation (14).
\
\ From the previous section, we know that Ax = Z, as in equation (15).
\
\ The summation of the inputs of an industry plus its value added is equal to its output, per the IO table.
\ Thus, as per equation (16).
\
\ Similarly, as per equation (17).
\
\ The Ghosh matrix, G, is equal to (I-B) -1 and allows us to see the changes in final output from the changes in value added.
