4. Government Intervention and Disequilibrium

Other Objectives

Governments can sometimes intervene in markets to promote other goals, such as national unity and advancement. Most people agree that governments should provide a military for the protection of its citizens, and this can be seen as a type of intervention. Growing a large and impressive military not only increases a country's security, but may also be a source of pride. Intervening in a way that promotes national unity and pride can be an extremely valuable goal for government officials.
