Greg Mankiw's Blog: Does free trade lower prices? Lots of econospeak in this short post, but I thought this conclusion was helpful.
So maybe when we hear people say that trade lowers prices, we should interpret the statement as meaning that trade lowers the price of a basket of consumer goods for a given price of labor. That is, trade raises real wages. This is one simple way of translating the basic Ricardian model (in which trade expands both trading partners' consumption opportunities) into a language that is a bit more familiar to the general public.
