This paper uses the Mincerian approach in an experimental way to examine the impact of education on household incomes (not labor earnings) of all workers (not just employees) across 162 countries. Our results are broadly similar to the conventionally estimated rates of return to education after allowing for the fact that earnings are only a part of total household incomes. We then apply the results to the case of Arab countries and find that our experimental approach can promisingly be used for the study of the impact of education not just on individual earnings of employees but also on total household incomes of all workers and more broadly on the economy and the labor market.
