(a) Calculate import, wage and other valueadded coefficients from Table 9.1 analogous to the intermediate input coefficients aij.

Check that for each industry, the sum of the intermediate and primary input coefficients is unity.

(b) In the text we used coefficients derived from the data of Table 9.1 to find the gross output levels implied by new higher levels of export demand. Use those new gross output levels to derive a new transactions table, assuming constant input coefficients for both intermediate and primary inputs.

Calculate the new level of GDP.
