This is from a web resource (CHRON) explaining Economics to business students, "Price elasticity of demand affects a business's ability to increase the price of a product. Elastic goods are more sensitive to increases in price, while inelastic goods are less sensitive. Assuming that there are no costs in producing the product, businesses would simply increase the price of a product until demand falls." There is some serious mistake in the last sentence of this explanation. What is it? Explain in short.
