Classical economists believe full employment is normal and unemployment is rare and temporary. They advocate for laissez-faire policies and argue government intervention disrupts the self-correcting market. According to Say's Law, supply creates its own demand so over- or under-production cannot occur. Classical theory assumes perfect competition, optimal resource allocation, expanding markets, and automatic investment of savings. Equilibrium in the labor market results from the inverse relationship between wages and employment matching the direct relationship between wages and labor supply. Equilibrium in the product market occurs where the direct relationship between interest rates and savings matches the inverse relationship with investment.
