"The underlying theory is straightforward. Children who are unwanted at birth are at risk of a range of adverse life outcomes and commit much more crime later in life. Legalised abortion greatly reduced the number of unwanted births. Consequently, legalised abortion will reduce crime, albeit with substantial lags."

"Many people would prefer that our hypothesis not be true—perhaps not recognising that the core finding is that when women can control their fertility the life outcomes of their children are greatly enhanced."

Really well-done article I thought, and I always appreciate the Economist for inviting people to write who they start beef with. :)
