The video introduces demand-side and supply-side economics. Demand-side economics focuses on the behaviors of all consumers, including consumer spending, firm investment, and government spending. Supply-side economics pertains to the behavior of all firms producing goods and services.
Government can attempt to influence aggregate supply through policies like changing corporate taxes, subsidies, and regulation laws. However, firms maintain control over their production, making supply-side policies unpredictable and thus less effective for fixing the aggregate economy.
Demand-side policies are more predictable. When the government alters its expenditures, it directly impacts aggregate demand. Similarly, changes in tax policy affect consumers' disposable income, instantly influencing aggregate demand, as people tend to spend more when they have more money and less when they have less.
