4. Government Intervention and Disequilibrium
Governments may also intervene in markets to promote general economic fairness. Government often try, through taxation and welfare programs, to reallocate financial resources from the wealthy to those that are most in need. Other examples of market intervention for socio-economic reasons include employment laws to protect certain segments of the population and the regulation of the manufacture of certain products to ensure the health and well-being of consumers.
