Market Failure vs. Government Failure

When markets fail, governments are often called upon to right fix the problem. But the call for government action is often naive, says Nobel Laureate Gary Becker, and fails quite often. 

What's the Latest Development?


While many are calling for a new government jobs program, Nobel Laureate Gary Becker says asking governments to solve market failures is often naive. Markets have uninformed buyers; governments, uninformed voters. Markets suffer from monopolies; governments, from duopolies created by two dominant parties. And while private financial companies took exaggerated risk in the run up to the financial crisis, so did the government-supported institutions of Freddie Mac and Fannie Mae. Government intervention must be a last resort, says Becker. 

What's the Big Idea?

Becker offers some guidelines for government action in the marketplace. "Governments should have the dominant role in the military and police areas, in the judiciary, in protecting against massive pollution, and in providing a safety net for its least fortunate members (private charities are important but do not do enough). On the other hand, when market failures are relatively small and likely to be temporary, as in monopoly situations or in exploiting consumer ignorance, government involvement should be minimal, as in minimalist anti-trust policies, and in allowing consumers generally to make their own decisions."

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
