摘要

几个世纪以来，银行业一直推动着世界的发展。一个需要分析的有趣问题是，金融产品的最佳利差反映了在跨期决策中不会给消费者带来经济扭曲的附加值。基于这些服务的重力方程，本文通过评估用利息之间的重力方程表示的纯利息在应用该价差后是否不变，来检验最近提出的移动比率——修正报价价差的最优性。结果表明，流动比率是价差的规范，对投资决策没有扭曲。关于财政政策，这一比例对金融交易税和金融服务增值税都起着关键作用。

The key role of quoted spreads in financial services and transactions

Banking has driven the development of the world for centuries. An interesting issue to analyze is the optimal spread on financial products reflecting the value added that does not generate economic distortions for consumers in intertemporal decisions. Based on a gravity equation for these services, this paper examines the optimality of a modified Quoted Spread, the recently-proposed mobile-ratio, by assessing whether the pure interest expressed as a gravity equation between interests does not change after applying this spread. Results show that the mobile-ratio is the specification of the spread with no distortions on investment decisions. Regarding fiscal policy, this ratio plays a key role for both the Financial Transaction Tax and the VAT on financial services.
