Still, in one area, a Tobin tax could provide an unmitigated benefit. Many of the largest, most precarious financial institutions now finance themselves via repo: they buy a long-term security (often government debt) and sell it, promising to buy it back the next day for a slightly higher price.
但是，在一个领域，托宾税可以带来十足的好处。许多大型危险金融机构现在正在使用回购协议来为自己融资：它们买入长期债券（通常是国债）并出售，承诺第二天以略高的价格回购。
