A New York Times article (July 6, 2011) summarizes the recent agreement to let Mexican truckers carry loads into US destinations, thus decreasing trade frictions (cost and time delays) at the US-Mexico border.  In turn, this agreement decreases Mexican tariffs on US products and agricultural exports.  Will this deal generate an overall increase in US trade with Mexico and benefit the US consumer ? Will the lower priced Mexican truck labor impact small US trucking firms disporportionately ? How will mixed loads with different US destinations comply with the need to track truck deliveries to prevent their use for commerce between US locations and who, ultimately, will bear the responsibility ?
