Introduction

Labor market polarization describes a structural shift in employment patterns characterized by growth in high-skill, high-wage jobs and low-skill, low-wage jobs, alongside a decline in middle-skill occupations. This phenomenon has been widely observed in advanced economies over recent decades and is closely linked to technological change, globalization, and evolving labor market institutions [1,2]. Understanding labor market polarization is essential for assessing its implications for inequality, productivity, and social mobility.

Discussion

A primary driver of labor market polarization is skill-biased and task-based technological change. Automation and digital technologies tend to replace routine tasks that are common in middle-skill jobs, such as clerical work and assembly-line production. At the same time, technology complements high-skill occupations that involve complex problem-solving, creativity, and advanced analytical skills. This leads to increased demand and wages at the top of the labor market, while routine middle-skill jobs shrink [3,4].

Globalization has reinforced these trends. The integration of global markets has exposed middle-skill manufacturing jobs in advanced economies to international competition and offshoring. Firms often relocate routine production tasks to lower-cost countries, reducing domestic demand for certain types of labor. In contrast, high-skill jobs related to management, innovation, and design are less easily offshored and often benefit from global market expansion [5].

Labor market institutions also influence the extent of polarization. Declining unionization, weaker collective bargaining, and more flexible employment arrangements have reduced wage compression, allowing greater dispersion in earnings. At the lower end of the labor market, growth in service-sector jobs—such as personal care, retail, and food services—has increased employment, but often at low wages and with limited job security.

Labor market polarization has important macroeconomic and social consequences. The erosion of middle-skill jobs can reduce opportunities for upward mobility and contribute to rising income inequality. Polarization may also weaken aggregate demand, as income growth becomes concentrated among high earners with lower marginal propensities to consume. Over time, these dynamics can affect economic growth and social cohesion.

Conclusion

Labor market polarization reflects deep structural changes in technology, trade, and institutions. While it has increased efficiency and innovation in some sectors, it has also created challenges related to inequality and job quality. Addressing polarization requires policies that invest in education and training, support worker transitions, and strengthen labor market institutions to ensure that the benefits of economic change are more broadly shared.
