Michael Greenstone on environmental economics … and basketball

World-famous economist Michael Greenstone tells Mike about his main professional mission: to apply the tools of economics to reduce human suffering. But that wasn’t always the case. No indeed. For many years, including all of college, Michael’s main goal in life was to have a career in the NBA. Happily for economics, Division III basketball at Swarthmore didn’t immediately translate to the desired outcome, and Michael found his way to natural resource-energy-climate economics via a short stint in labor economics. Now he and his colleagues are pushing forward on an extremely challenging agenda designed to bring economics into the realm of rigorous nature science. To meet the goal, as Michael puts it, a study should have a global analysis, with plausibly causal mechanisms, and consideration of the true range of adaptations that society would bring to bear in the face of climate change. We’re not there yet, but the pathway is clearer than ever before.

Michael Greenstone.

Much as Michael assaulted the hoop back in his Swarthmore days, he now destroys Mike’s ideas about what economics is, and could be. Outside the field, economics has, at least in some quarters, a dodgy reputation: toy models with no practical application, ridiculous assumptions (witness the many ‘assume a can opener’ jokes, inability to predict events like the 2008 economic collapse, untestable hypotheses, to name a few. But the field is changing rapidly, due to, finally, the influx of data, controlled experiments, and computational power. Economics now has the power to identify, investigate, and solve major real-world problems. In one project, Michael co-led a team to identify the systemic conflicts of interest at work in Gujarat’s power plant inspections, and devised a novel system that led to a 30% reduction in the notorious atmospheric pollutant PM 2.5.

Yet Michael is not an environmentalist. Instead, he favors applying agnostic cost-benefit analyses to identify the most efficient ways of reducing suffering and increasing well-being. That might involve climate, but it might not. In fact, Michael favors a focus on what he calls the global energy challenge, rather than the climate problem. The two are linked, but ultimately the grand challenge is to provide inexpensive and reliable energy for everyone while minimizing negative health consequences and avoiding disruptive climate change. It’s a difficult-to-construct three-legged stool … but like all three-legged stools, once built, they don’t wobble.

The Atlantic’s Rob Meyer on climate journalism

Sometimes papers in Nature are incomprehensible to anyone other than a hard-core specialist. Yes, we use press releases, News & Views, and other reporting to make the leap to our broader readership. But for bringing science to the general public, no amount of Carl Sagans, Neil deGrasse Tysons, or Bill Nyes is going to get the job done. You need journalists. Journalists like Rob Meyer from The Atlantic, who are producing an astonishing amount of great content on topics like the Paris Agreement, fracking regulations, and Antarctica. Rob talks me through his path from music major to twitter procrastinator to Atlantic writer. I flip the usual Nature-related questions around to Rob: how do you select stories, frame them for your audience, and discuss the policy implication? And what is the rationale for the New York Times hiring Bret Stephens? Definitely a story there.

Bronwyn Wake chief editor of Nature Climate Change

How, exactly, does one get to be an editor of a Nature-branded journal? What do we do? How do we decide what to publish? And what’s up with all our journals? In this episode of Forecast, I hash out these issues with Bronwyn Wake, the chief editor of Nature Climate Change. But don’t worry … if you’re thinking about becoming an editor, working in a bar is not a prerequisite. Continue reading →
