问题如下：
Which of the following factors would best justify a decision to avoid investing in a country’s sovereign debt?
选项：
A.Freely floating currency
B.A population that is not growing
C.Suitable checks and balances in policymaking
解释：
B is correct.
Among the most important considerations in sovereign credit analysis is growth and age distribution of population. A relatively young and growing population contributes to growth in GDP and an expanding tax base and relies less on social services, pensions, and health care relative to an older population.
之前也有个题……我想问下这个Sovereign Bond的和Population growth的点本身都是如何推出来的？
