The Key to Ending Ivory Trade is not Bans, but Increase in Supply of Ivory in the Market
In economics, there is a type of product called "Veblen good" that does not contradicts the normal supply-and-demand relationships. For a normal good, a decrease in supply corresponds to an increase in price, leading to a corresponding drop in demand as consumers reduce consumption and/or seek out cheaper substitutes for the now more expensive product. But for a Veblen good, while decrease in supply also leads to a price increase, demand actually surges, with consumers assigning higher value to the good due to the higher price of the good.
