Growth, to an economist, is usually seen as a good thing. Money, economies, social welfare… most economic theory assumes that if some of these things is good, more is better. So, too with population growth. Skim the mainstream news, and you’ll see lots of stories about the perils of Social Security, for example and how the working population won’t grow fast enough to keep SSI viable. Make it bigger, faster is the mantra. Our next guest, though, thinks there’s nothing wrong with putting the brakes on — in fact, the climate itself may benefit. David Rosnick is an economist with the Center for Economic and Policy Research in Washington, D.C. He is the architect of CEPR’s online calculators, including the Housing Cost Calculator, which compares the cost of owning a home relative to renting. He received his Ph.D. in Computer Science from North Carolina State University and his M.A. in Economics from George Washington University.
