Introduction to Economics

Trace money’s evolution from barter to coins and receipts. Explain how metal money addressed storage and transport problems, and the rise of electronic and digital currencies such as Bitcoin.

Defines inflation as a steady rise in the general price level and explains how money buys less over time, highlighting ideal inflation rates and risks of hyperinflation or deflation.

Explore gross domestic product as a key indicator of economic activity and its calculation by Y = C + I + G + X - M.

Explore how demand and supply determine price and the quantities demanded and supplied. Learn how prices reflect these forces and guide resource allocation in the market economy.

Explore how higher prices reduce demand due to opportunity costs, while higher prices increase supply as producers expand output. Consider time and long-term demand shaping production.

Examine the supply and demand relationship through a crude oil example, showing how price shifts with rising demand and supply responses, and how excess supply can lower prices.

Explore economic equilibrium where demand and supply meet, ensuring the quantity supplied equals the quantity demanded. Understand why real market equilibrium is theoretical due to price volatility.

Explore how physical and financial assets gain value, and how stocks, bonds, and markets—primary and secondary—set prices, liquidity, and the roles of brokers.

Explore micro and macro economics by examining how individuals and firms set prices, demand, and values, and how GDP, resources, trade, inflation, and unemployment shape decisions.

Explore japan's postwar economic miracle driven by a production culture, government policies to reduce imports, and export-led growth that rebuilt national wealth and global competitiveness.
