"Economics is like baking a cake," said Wolfers, professor of economics and public policy at the University of Michigan. "You put a whole lot of ingredients into the mixing bowl and we bake our economic cake. Sometimes, though, in America, we discover there's a particular ingredient we don't have enough of. And so what we do is, we Instacart that ingredient, which is we offer an H-1B visa so we can keep baking that beautiful cake."
