This document discusses labor markets and the factors that impact supply and demand for labor. It defines a labor market as a market where people offer their skills in exchange for compensation like wages. The labor market reaches equilibrium when the supply of labor equals the demand. Technological advances are changing the types of jobs available, increasing demand for skills that complement new technologies while putting low-skilled jobs at risk. Investing in education, training, factories and machinery can raise future living standards by increasing productivity and wages. Firms provide both general and specific job training to workers.
