 | | In the latter model, the world is treated as a single compound region in that all regions'’ factors are pooled; that is, production takes place in the regions whose technologies are chosen and they are able to use, at their factor prices, factors that may originate in other regions. |
 | | The equality of factor payments with the value of final deliveries for region $i$ \eqref{A3} is derived by transposing the $i^{\rm th}$ matrix equation in \eqref{A2}, multiplying through by the vector of output, $x_i$, and substituting from \eqref{A1}. |
 | | The dual \eqref{C2} solution includes (besides world prices and region-specific factor scarcity rents) a vector of shadow prices, $\alpha_i$, corresponding to the last $m$ inequalities in the primal, that determine a benefit-of-trade rent and assure that world prices are high enough to accommodate this rent. |
