            : a scalar, the number of urban workers
            : a scalar, the number of rural workers
            : a scalar, the level of labour supply

            If the matrix is partitioned with the economic and demographic activity, then
            it can be converted to a simple form of the equation as follows:
                                        −   −     
                                      [           ] [  ] = [   ]
                                       −

            set at zero, and the number of active economic population or labour supply
            of the country. The equation can then be rewritten as:
                                                                  22

            Through the detailed analysis of each element of this inverse matrix, we define
            them as in Table 1 and 2..

            ‘urban  and  rural  labour  allocation  multiplier’,  more  simply,  ‘urbanisation

            1  The model assumes that there are no commuting workers from rural areas to urban areas for
            their job. It means that rural workers work only at villages as long as they live in the
            countryside.
