Welcome to the May issue of Vox’s The Highlight

Raj Chetty, an economist and professor, has a plan to radically change how we think about economics. And for him, it all starts with Econ 101 — oftentimes the only exposure students have to the field of economics — and the dominant school that ignores that free markets often fail. Chetty, who teaches intro course Econ 1152 at Harvard, focuses on empiricism and the idea of economics as a tool to fix social problems rather than the traditional emphasis on supply and demand. This month’s cover story explores how this course has the potential to shift the next generation’s approach to economics.

Also in this issue, Vox’s TV critic Emily VanDerWerff handpicks the 25 most influential TV episodes, without which we wouldn’t have today’s golden age of television. We also explore the history of electroconvulsion therapy with this personal story about the treatment’s success and how it is viewed with suspicion today.

Finally, we look at how social media continues to shape our world, starting with an interview with media studies Kate Eichhorn on how the internet prevents us from distancing ourselves from our past actions. We also check in with early 2000s internet phenomenon “David After Dentist” to see how going viral impacted his life in an era before kid influencers became the norm.
