Investigating the causes of inflation, including demand-pull and cost-push factors.
Imagine you wake up and find that every single person in your city has been given 500?
Inflation is the general increase in prices and the fall in the purchasing power of money over time. It doesn't mean just one item got expensive; it means almost everything is getting more expensive at once. When inflation happens, your dollar buys less than it did yesterday. Economists measure this using the Consumer Price Index (CPI), which tracks the cost of a 'basket' of common goods like milk, gasoline, and rent. If the basket cost 105 this year, the inflation rate is . While a little inflation (around ) is considered normal for a growing economy, rapid inflation can cause chaos.

Demand-pull inflation occurs when the demand for goods and services grows faster than the economy's ability to produce them. Think of it like a popular concert: if 10,000 people want tickets but there are only 5,000 seats, the price of those tickets will skyrocket. When consumers have lots of extra cash and feel confident about the future, they spend more. Because factories can't instantly build new machines or hire more workers to keep up, they raise their prices to manage the high demand. In short: the 'pull' comes from the buyers.
1. A company releases 100 pairs of limited-edition sneakers for 1,000 or more. This is demand-pull inflation on a small scale.
Cost-push inflation happens when the costs of production increase for businesses. If it becomes more expensive to make a product, companies will pass those costs on to you, the consumer, to maintain their profit margins. Common 'pushes' include rising wages for workers or an increase in the price of raw materials like oil or steel. For example, if the price of gasoline rises, it costs more to ship bread to the grocery store. To cover that extra shipping cost, the bakery raises the price of the bread. Here, the 'push' comes from the sellers' side.

If a massive drought destroys half the world's wheat crop, what kind of inflation would likely hit the price of cereal?
Answer
Cost-push inflation, because the cost of the raw material (wheat) has increased.
Imagine an island economy with 100 coconuts and 1.00. 2. The island king prints another 200 total. 3. There are still only 100 coconuts. 4. To balance the economy, the price of each coconut will rise to $2.00. The money supply doubled, so the prices doubled.
Inflation doesn't affect everyone equally. The biggest 'losers' are people on fixed incomes, such as retirees who receive a set amount of money every month. If their check is 1,000 ten years ago and inflation makes $1,000 worth much less today, you are essentially paying back the loan with 'cheaper' dollars than the ones you originally received.
