Endogenous variables

\( {D}_y^M \)

Market demand for final output (y = CPO)

\( {D}_y^{\mathrm{EU}},{D}_y^{\mathrm{ROW}} \)

Demand for y from EU and Rest of the World (ROW), respectively.

\( {D}_y^{\mathrm{Do} m},{S}_y^{\mathrm{Do} m} \)

Domestic demand and domestic supply for y, respectively.

D i , S i

Derived demand for and supply of ith primary input

\( {P}_y^M \)

Market price of y

\( {P}_y^{\mathrm{EU}},{P}_y^{\mathrm{ROW}} \)

Parameters

\( {\varepsilon}_y^{\mathrm{Dom}} \)

Own price elasticity of domestic demand for y.

\( {\varepsilon}_y^{\mathrm{EU}},{\varepsilon}_y^{\mathrm{ROW}}, \)

\( {\alpha}_y^{\mathrm{EU}},\ {\alpha}_y^{\mathrm{ROW}} \)

Share export demands from of EU and ROW for y in total market demand

\( {\alpha}_y^{\mathrm{Dom}} \)

c i

The cost share of ith primary input with respect to total cost of producing y

v i
