We like to think that we still live in a free-market economy, but our world is increasingly ruled by vast networked platforms (from Google and Facebook to our financial markets) that are ruled by algorithms. It is those algorithms that decide who gets what and why. It's time to take a closer look at what it takes to manage these digital djinns, who promise to give us what we say we want, but parse our requests so precisely that it is often not what we really want. My talk to the National Association of Business Economists #TEC2018 Conference in San Francisco on October 30, 2018. Many of the slides are just pictures, so be sure to read the narrative in the speaker notes.
