Is there an alternative metric to GDP that measures a country's assets rather than flows?

Answer 1

You you actually trying to measure the wealth of a Nation. You can look at the Capital stock, that includes the housing stock and the Blue Book value of automobiles in durable goods. The labor force and the value of land. By far the largest component is human capital so you would want to look at the level of Education of the labor force or labor productivity if you took the average product of labor and looked at the average age of a worker an estimated how many years left before retirement you might come up with a reasonable estimate of that.

If If you have any questions in macroeconomics or any economic please don't hesitate to reach out.
