The Origins and Evolution of Economics
📌 The term "economics" originates from the Greek word oikonomia, meaning "to manage the household," first defined by Aristotle regarding managing income and expenses.
🧑‍🤝‍🧑 Early economic activity preceded formal definitions and included practices like barter and fulfilling needs through simple means like hunting and gathering.
🪙 The need for efficiency led to the development of money (medium of exchange), which the speaker defines as a product of mutual agreement and communication.
📜 Modern economics finds its foundation in the work of Adam Smith in 1776 with *The Wealth of Nations*, focusing on production and labor, suggesting that individual self-interest leads to societal harmony via the "invisible hand" (market mechanism).

Key Economic Theories and Conflicts
☭ Karl Marx criticized capitalism, which he derived from Smith's work, arguing it led to the exploitation of labor for maximum profit, detailed in *Das Kapital*.
📉 The Great Depression (1929-1930s) marked a turning point, leading to the development of Keynesian Theory by John Maynard Keynes in *The General Theory*.
🏛️ Keynesian economics challenged classical economists by affirming the existence of structural unemployment and arguing that supply does not automatically meet demand; it advocates for government intervention (e.g., spending, stimulus like BLT) during recessions.
📉 In the 1970s, the appearance of stagflation (high inflation and high unemployment) invalidated the simple relationship described by the Phillips Curve, leading to the adoption of Neoliberalism (advocated by Friedman and Hayek), which pushed for minimal government interference.

Modern Economic Analysis and Policy Challenges
🧠 Behavioral economics has proven that economic decisions are not always rational, a concept highlighted during the 2008 financial crisis (subprime mortgage crash), which was addressed by reapplying Keynesian government spending.
🧪 The core lesson is that economics is not a fixed theory but an analytical science that must adapt to context, situation, and society.
😷 Inelastic demand demonstrates the raw nature of the market; for necessities like masks during COVID-19, moral appeals are ignored, and consumers will pay high prices due to a lack of substitutes.
🚫 Poorly conceived government policies, often driven by populism rather than technical expertise, lead to unintended consequences, such as consumers sourcing untaxed, cheaper illegal goods (e.g., certain cigarettes) or buying high-value items like iPhones abroad due to strict local content requirements (TKDN).

Key Points & Insights
➡️ Economic terms like "capitalism" were coined later (by Marx) to critique existing frameworks, not necessarily stated in the original texts (like Smith's *Wealth of Nations*).
➡️ Keynesian theory suggests that during economic crises, the government must intervene through spending to stimulate consumption and keep the money circulating, countering the classical view that the market self-corrects.
➡️ When regulations like price caps are imposed against market mechanisms (e.g., setting a maximum price for cooking oil bought at a higher price), the result is often hoarding and the emergence of black markets.
➡️ Policy success requires technocratic precision over populist appeal; policies intended to solve one problem (like high cigarette taxes to curb smoking) can create another (a flourishing illegal market).
