In 2002, the U. S. Fish and Wildlife Service proposed banning imports of beluga caviar to protect the beluga sturgeon in the Caspian and Black seas, whose sturgeon population had fallen 90% in the last two decades. The United States imports 60% of the world's beluga caviar. On the world's legal wholesale market, a kilogram of caviar costs an average of $500, and about $100 million worth is sold per year. What effect would the U. S. ban have on world prices and quantities? (In 2005, the services decided not to ban imports.)
