The Division of Labour Is Limited by the Extent of the Market
I am looking for a vendor of jewelry-making supplies. (Shh, don't tell Bob M., but I'm making him a little something special for under his tree!) I'm currently in Milford, PA, and I can't find anything within about a 30-mile radius around my house. I called my wife and asked her if she knew of anything like that in Brooklyn. Of course, there is just such a shop about ten blocks from my house.
