Economics is the study of finances and the movement of wealth. When people hear the word "economics," some people think of a country’s economy. If a company is selling a variety of products, they will need to price their products according to certain factors. If many people want to buy the product, then the company can price the product at a high price. This is called demand. Supply also plays a part in the product’s price. If there isn’t a lot of product, then the price will increase. Sometimes, a country may need a product that they can’t produce. They will have to import it from another country that does make that product.
