Isotoon explains economics by showing what moves and why. Ask about supply and demand, inflation, interest rates or market failure and get a short animated video of the curves, prices and incentives shifting.
A tiny island economy has 100 loaves of bread and $100, so a loaf costs $1. The printer doubles the money to $200 while the bread stays the same, more dollars chase each loaf, the price rises from $1 to $2, and each dollar buys less.
Scenes, in order:
Economics is a set of models for how people and markets respond to change. Ask what happens when something shifts and watch the curves, prices and incentives move.
If the amount of money in an economy grows much faster than the goods and services it produces, more money is chasing the same goods. Sellers can raise prices and still sell everything, so the price level rises and each dollar buys less. Economists sum this up with the quantity equation, MV = PY: if velocity (V) and output (Y) stay roughly steady, more money (M) shows up as higher prices (P).
When demand and supply both increase, the quantity sold rises for certain, but the price can go up, down or stay the same, depending on which shift is bigger. When demand rises and supply falls, the price rises for certain and the change in quantity is the uncertain one. On a test, shift both curves and check which result holds however large each shift is.
A central bank raises its policy rate, which pushes up the rates on loans, mortgages and credit cards. Borrowing gets more expensive and saving more rewarding, so households and businesses spend and invest less. With less spending chasing the same output, prices rise more slowly, usually after a lag of months and sometimes at the cost of higher unemployment.
