The United States has a great consumer demand for health care services. The supply of these services or products, such as new medications or medical equipment, is affected by many factors. Select a service or product that may be in demand by the health care consumer now or in the future. Write a 1,050- to 1,400-word paper on your selected service or product that discusses the effects of consumer demand on medical care services or products versus the economic variables of cost, access, and supply. Support your perspective and rationale for the continued provision of a current service, or for the implementation of a new service or product, based on economic principles or supply chain models. Cite a minimum of three sources. Format your paper consistent with APA guidelines.
