The restricted wheat supply to Mexico will shift supply back to the U.S. market, causing excess supply in<br />

the U.S. market at the original price <strong>and</strong> a reduction in the U.S. price. The lower price will, in turn, reduce<br />

U.S. supply, raise U.S. dem<strong>and</strong>, <strong>and</strong> cause a reduction in U.S. export supply.<br />

These price effects are identical in direction to the price effects of an import tax <strong>and</strong> an import quota by<br />

the importer country, <strong>and</strong> an export tax by the exporting country.<br />

A new VER equilibrium will be reached when the following two conditions are satisfied:<br />

MDMex(PMexV)=QØØØ<br />

<strong>and</strong><br />

XSUS(PUSV)=QØØØ,<br />

where QØØØ is the quantity at which the VER is set, PMexV is the price in Mexico after the VER,<br />

<strong>and</strong> PUSV is the price in the United States after the VER.<br />

The first condition says that the price must change in Mexico such that import dem<strong>and</strong> falls to the VER<br />

level QØØØ. In order for this to occur, the price in Mexico rises. The second condition says that the price<br />

must change in the United States such that export supply falls to the VER level QØØØ. In order for this to<br />

occur, the price in the United States falls.<br />

The VER equilibrium is depicted graphically in Figure 7.35 "Depicting a VER Equilibrium: Large Country<br />

Case". The Mexican price of wheat rises from PFT to PMexV, which is sufficient to reduce its import<br />

dem<strong>and</strong> from QFT to QØØØ. The U.S. price of wheat falls from PFT to PUSV, which is sufficient to reduce<br />

its export supply also from QFT to QØØØ.<br />
