Summary and Exam Tips for Economic Thought
Economic Thought is a subtopic of Introduction to Economics, which falls under the subject Economics in the IB DP curriculum. This topic explores the evolution of economic ideas from the 18th century to the present day. Adam Smith, known as the Father of Economics, introduced the concept of laissez-faire and the invisible hand, advocating for minimal government intervention in markets. In the 19th century, classical economics emerged, with key ideas like Say’s Law and utilitarianism. Say’s Law posits that supply creates its own demand, while utilitarianism focuses on maximizing happiness for the greatest number. The Marxist critique challenged classical economics, predicting capitalism's eventual collapse due to its internal contradictions.
The 20th century saw the rise of Keynesian economics, which emphasized the need for government intervention to manage economic cycles, contrasting with monetarism and new classical economics that supported laissez-faire principles. In the 21st century, behavioral economics examines how psychological factors affect economic decisions, challenging traditional theories of rational consumer behavior. The concept of a circular economy is also gaining importance, promoting sustainability by minimizing waste and encouraging resource regeneration.
