Given:
Duration = 10 years
Yield to maturity = 10%
To find: Bond volatility.
Solution:
Volatility (in percentage) = Duration / (1+yield)
Now putting values in the formula,
10 / (1+10%)
10/ (1+10/100)
10/(1+0.1)
10/1.1 = 9.09%
So, bond volatility is 9.09%.
Answer:
I'm not sure that the number of cell phones users per 1,000 people can be a good economic indicator. E.g. there are currently more than 1.6 billion cell phone users in China, which means that some people obviously use more than 1 cell phone (Chinese population is around 1.4 billion people). But China's HDI is 0.752 (2017) and that places China at the number 85 spot, which is really not a good place.
While other countries like Norway have less than 5 million cell phone users with a population of more than 5.35 million people. But Norway is ranked as the number 1 country in HDI.
