An increase in demand while supply decreases is to market price rising as an increase in consumer confidence is to what?

When demand increases while supply decreases, there are more people wanting a product but fewer products available, which causes the market price to rise. Similarly, when consumer confidence increases, people feel more secure about their finances and are more willing to spend money. This increased willingness to spend usually leads to a rise in demand for goods and services. As demand increases due to higher consumer confidence, prices tend to rise as sellers adjust to the greater interest from buyers. For example, if more people believe they will keep their jobs, they might buy more cars, leading to higher prices for vehicles.
