Autarky: Equilibrium prices (cont.)<br />

International Commercial Policy<br />

<strong>The</strong> <strong>Ricardian</strong> <strong>Model</strong><br />

Hence, the equilibrium relative price of a good equals<br />

the opportunity cost of producing that good in the<br />

absence of international trade.<br />

This is because relative prices must adjust so that<br />

wages are equal in the wine <strong>and</strong> cheese industries so<br />

that both wine <strong>and</strong> cheese are produced.<br />

If P C /a LC = P W /a LW � P C /P W = a LC/a LW workers will<br />

have no incentive to work solely in the cheese industry<br />

or the wine industry.<br />
