"In the news, economists are often portrayed as number crunchers hidden away in universities. But they also journey out into the world, discovering problems and then charting a course to a solution. By applying economic theories to the shortage of kidneys, scientists have been able to save lives, cut medical costs, and reduce misery. Their innovations have spurred medical progress.
“Economics is about the real world,” said Alvin Roth, a Stanford University economist, when he won the Nobel Prize in 2012 for his work on matching markets, including the kidney donor matching problem."
