Introduction to Economics
📌 Economics is a social science studying economic activities such as production, consumption, and distribution.
💰 It analyzes how society makes choices and manages scarce resources to enhance welfare (kesejahteraan).
📉 The field arises from scarcity, where limited resources contrast with unlimited human wants, forcing choices.

Microeconomics vs. Macroeconomics
🔬 Microeconomics focuses on the behavior of individual economic units like households (maximizing utility) and firms (maximizing profit).
🌎 Macroeconomics studies the economy as a whole (aggregate), analyzing the collective behavior of all consumers, firms, and the government within a nation.
📊 Key differences: Micro analyzes individual markets and resource allocation; Macro analyzes topics like GDP, inflation, and unemployment.

Key Macroeconomic Variables
📈 Major macroeconomic variables include Real GDP (PDB RIL), which measures the final value of goods/services based on a base year's prices, indicating economic growth.
🔥 Inflation is defined as a general rise in prices across the economy; conversely, a general price decrease is deflation.
📉 Unemployment is the proportion of the labor force that is not working, a critical measure of national economic health.

Macroeconomic Conditions and Terminology
📉 A significant drop in Real GDP, especially if sustained for two consecutive quarters, indicates a recession. A very deep and prolonged recession is termed a depression (e.g., the Great Depression of the 1930s).
😖 Stagflation is a critical economic combination characterized by high inflation, falling GDP, and high unemployment.
📊 Historical data shows Indonesian Real GDP generally increases, though severely impacted by the COVID-19 pandemic in 2020.

Key Points & Insights
➡️ Understand that economics is fundamentally about managing scarcity through societal choices aimed at increasing welfare.
➡️ Microeconomics deals with individual optimization problems (utility/profit maximization), whereas Macroeconomics aggregates these behaviors nationally.
➡️ The three primary indicators for macroeconomic health are Real GDP, the inflation rate, and the unemployment rate.
➡️ Recognize economic terms: Hyperinflation is extremely high inflation, and stagflation is a harmful mix of high inflation, low GDP, and high unemployment.
