The Financial Stability Board, a committee of global supervisors, has floated the idea of a global utility that would match supply and demand of currencies.

金融稳定理事会是一个全球监督委员会，它提出了符合全球货币全球用函念。

First, we construct a utility function, where Y equals income and X equals the cost of services.

首先，我们构建一个用函，这里Y轴表示收入，X轴表示服务成本。

It can be said that M1 loves F1 if her welfare enters his utility function.

可以说，如果F1福利进入了M1用函，那么M1就爱上了F1。
