Some regions are obviously more dependent upon export jobs than others.
NYS is well above the national average, whereas North Dakota is well below the national average. Export jobs can be found across all parts of the service sector, as well as in the Primary and Transformative sectors. Thus, the popular basic-nonbasic approach is not very reliable. Export Base Models Export base models draw upon the same logic, but seek to explain regional or national income growth in terms of export activity. The model supplies a parameter estimate which describes the statistical relationship between income growth and export growth.
