National Productivity and Workflow Modeling

Nigeria exports unrefined oil to the U.S. then pays for refined oil for domestic consumption. The net effect is that Nigeria pays for the service of refinement of oil. I see no mention of this in the non-existent models I also see no mention of that characterize Nigerian Econometrics and "the order of all things." I am one of them, the "all things" men. I love being one of them... :-)
