原罪
There are three different measures of original sin in economics literature. These measures are defined mathematically as one minus the fraction of own currency-denominated securities in the relevant total. Original sin measures range between 0 and 1. A high measure of original sin indicates that a country suffers from high level of original sin. Thus, a country that issues all of its securities in foreign currency would have an original sin measure of one, while a country that issues all of its securities in its domestic currency would have an original sin measure of zero.
