I don't understand what the term
Gross National Saving is for. According to the world factbook, it represents the following:
Gross national saving is derived by deducting final consumption expenditure from Gross national disposable income, and consists of personal saving, plus business saving, plus government saving, but excludes foreign saving. The figures are presented as a percent of GDP. A negative number indicates that the economy as a whole is spending more income than it produces, thus drawing down national wealth (dissaving).
This represents the sum of savings by person, company, and government. But what is this beneficial to? Is a country that has high GNS more stable in finance? When should one look at this statistics to gauge what? In financial stability, is this a better indication than national debt as a percent of GDP, the dependency rate on government bond, or something others?
