*Economist* symposium on *The Great Stagnation*

You will find it here, with contributions from Viral Acharya, Scott Sumner, Hal Varian, and Paul Seabright.  From elsewhere, Noah Smith cautions economists not to invoke technology too often.  Brad DeLong chimes in.  From a few years ago, Austan Goolsbee measures the consumer surplus from the internet; his numbers do not refute the standard view that median income growth has become much much slower.
