A market economy deals with scarcity by using prices for direct production and rational consumption of resources. Price signals to producers that the greatest demand for any product or service is at any given time and encourages producers to find the most efficient means to fulfill it with limited resources. The higher price also encourages consumers to ration their consumption in order to save money or replace a product or service that is less scarce to meet their needs. In most cases, a market economy will provide the most efficient distribution of goods and services.
