The market segmentation model was developed to accommodate the differences in job markets. For example, lawyers and fashion designers work in different markets. Such markets arise from the division of labor, increasing differentiation and specialization. These workers are unable to switch between occupations because they require different skills and investment in training and qualifications. For example, nurses and doctors form separate occupational labor markets even though they work side by side in the same organizations. Geographical labor markets emerge because of the costs and disruption workers incur in changing locations. As a result, wages for the same work can remain higher in some locations than others. Conversely, employers would incur costs and disruption if they attempted to relocate to an area of lower labor costs, and might experience increases in non-labor expenses. Cultural differences such as preferences for leisure time versus work may follow geography. As ever more work becomes transacted over digital networks, in some industries, geographical labor markets have become less relevant, and we have seen the rise of a so-called planetary labor market. Geographical segmentation also occurs on a global basis, specifically between developed and less-dedeveloped countries. However, when labor migrates to developed countries, migrants tend to remain within their original segment, receiving less compensation than native workers. One study found that
neoliberal globalization had expanded labor market segmentation. It found that in the West, nations import capital, consumer goods and services exported by countries in the rest of the world, where lower wage workers produce the exports.
Sectors One important segmentation is primary/secondary (
dual labour market). The two markets allow limited movement between them. The concepts of primary and secondary labor markets have now passed into conventional thought. The two key formulations are labor market theory and internal labor market theory. The labor market segmentation theory revolves around the identification of a split between two analytic divisions in the economy and the labor market. ==See also==
