The promise of NYT Now

There are few if any media outlets that can really go up against the big social networks and have a prayer of stealing away attention. The New York Times might be an exception. When I first heard about NYT Now I didn’t think twice. It seemed like yet another addition to an already complicated, expensive

Who cares if the stock market is rigged?

One of the most interesting bits of the debate over high frequency trading sparked by Michael Lewis’s new book is the question of why we should care that some Wall Street firms are ripping off other ones.

How will humans add value to algorithms?

Last month, I wrote a piece at HBR about how humans and algorithms will collaborate, based on the writings of Tyler Cowen and Andrew McAfee. The central tension was whether that collaboration would be set up such that algorithms were providing an input for humans to make decisions, or whether human reasoning would be the

Depending on who you ask, the incomes of the American middle class over the past few decades have either a) risen only a little b) stagnated, i.e. stayed flat or c) declined. When President Obama declared in his State of the Union speech that family incomes had “barely budged” from 1979 to 2007, The Washington
