auctions
拍卖
These are usually associated with the sale of livestock, antiques and works of art. But in recent decades, they have been favoured by economists as a means of ensuring that sellers get the best price for a wider range of assets. For example, governments have used auctions to sell off parts of the electromagnetic spectrum to mobile telecoms companies.
这些通常与牲畜、古董和艺术品的销售有关。但近几十年来，它们一直受到经济学家的青睐，被视为确保卖家为更广泛的资产获得最佳价格的一种手段。例如，政府利用拍卖将部分电磁频谱出售给移动电信公司。
