Has our culture's obsession with innovation led us to neglect the fact that things also need to be taken care of?

For soccer fans, it's easy. For the rest of us? Not so much, especially since the U.S. team didn't qualify. So here's what to watch for even if you have no team to root for. Because the World Cup isn't just a gargantuan sporting evént; it's a microcosm of human foibles and (yep) economic theory brought to life.

We are in the midst of a historic (and wholly unpredicted) rise in urbanization. But it's hard to retrofit old cities for the 21st century. Enter Dan Doctoroff. The man who helped modernize New York City — and tried to bring the Olympics there — is now C.E.O. of a Google-funded startup that is building, from scratch, the city of the future.

Nearly two percent of America is grassy green. Sure, lawns are beautiful and useful and they smell great. But are the costs — financial, environmental and otherwise — worth the benefits?

Corporate Social Responsibility programs can attract better job applicants who'll work for less money. But they also encourage employees to misbehave. Don't laugh — you too probably engage in “moral licensing,” even if you don't know it.

Sure, medical progress has been astounding. But today the U.S. spends more on healthcare than any other country, with so-so outcomes. Atul Gawande — cancer surgeon, public-health researcher, and best-selling author — has some simple ideas for treating a painfully complex system.

Three former White House economists weigh in on the new tax bill. A sample: "The overwhelming evidence is that the trickle-down, magic-beanstalk beans argument — that's just nonsense."
