Suppose Bob applies for a remote position (so no visa or even travel involved) on a company based in the United States and his research indicates that the average salary for the position is $s ($ = USD dollars) per year.
Bob will be paid in his local fictitious currency φ, and $1 is worth φ10.
Something tells me it would be naive to assume Bob should simply ask for φ10*s, as cost of living in his country might be lower than in the United States. On the other hand, it would be too cheap for the company to pay him φ2*s, right?
How can Bob assess his worth in his local currency? Are there other factors that weight in to reach a reasonable value?
