Predict how each of the following economic changes will affect the equilibrium price and quantity in the financial market for home loans. Sketch a demand and supply diagram to support your answers. The number of people at the most common ages for home-buying increases. People gain confidence that the economy is growing and that their jobs are secure. Banks that have made home loans find that a larger number of people than they expected are not repaying these loans. Because of a threat of a war, people become uncertain about their economic future. The overall level of saving, in the economy diminishes. The federal government changes its bank regulations in a way that makes it cheaper and easier for banks to make home loans.
