The traffic curse with adding more lanes is like there’s a price signal (expected travel time) that people are responding to, so you can’t reduce market volume (or increase the number of unsold goods) by increasing supply, since this drops price and demand rises in response. This is just Jevon’s paradox you silly goose. I think this happens whenever goods have a price elasticity greater than 1? This is connected to induced demand. This is also called Braess’ paradox.

  • how does Jevons paradox relate to Veblen goods?
