The Government of Malaca has decided to sell pollution permits that will allow people to discharge pollutants into its largest freshwater lake. Each permit represents the right to discharge one tonne of pollutants.

This means that the auction starts at a very high price, which is reduced in steps until the price reaches a level that will result in all 19 tonnes of pollution permits being sold at the same price. The results of the bidding are shown in table below.
