Apologies for the radio silence. Job market and all.

Was fortunate enough to attend an event with Erik Brynjolfsson and Andrew McAfee yesterday discussing “The Second Machine Age” (coming out Jan. 20).

It’s in the same field as Tyler Cowen’s “Average is Over”, discussing how technological advances might reshape society – with emphasis on “might”, as they see room for current decisions to affect future outcomes.

I think we’ve heard a lot about how as machines get smarter and take over more cognitive jobs, the big question is what those displaced workers will do. As much as this will affect workers in America, the question is frankly even more relevant for developing countries. Developing countries often compete on the basis of low-cost labour. What will happen when that path to development is cut off? While a small fraction of those in the U.S. can be expected to benefit extraordinarily from the new system, we can expect even fewer from developing countries to reap such rewards.

Highly important topic for anyone interested in development.

Struck by several things in Mario Macis’ presentation today at ASSA. He reported results from an experiment in which half of participants were randomly given the option to broadcast their donation activity to friends on Facebook using an app, “HelpAttack!”.

First item of note: out of more than 6 million Facebook users reached through advertizing, there were 2,000 likes and only 18 processed pledges. How sad!

Second: there were 0 additional pledges through network effects.

Additional results in the paper, but these stood out to me. It’s possible that one needs direct solicitation from one friend to the next in order to observe peer effects. Petrie and Smith, Jonathan Meer, and Catherine Carman have also apparently studied this question in alternate settings with more positive results.

I must admit to being disappointed at how, during the two crowdfunders AidGrade has done, people would routinely sign up to be notified when more data came out but at the same time would not be willing to contribute to the production of said data. It’s completely natural but a bit sad.
