This select group of firms has control over the price and has high barriers to entry. The products that the firms produce are often nearly identical and, therefore, the companies, which are competing for market share, are interdependent as a result of market forces.6) the relation between these two factors determines the price of a commodity. This relationship is thought to be the driving force in a free market. As demand for an item increases, prices rise.

Across:
1) led to improvements in human longevity and health3) is a market structure in which there is only one producer/seller for a product. In other words, the single business is the industry. Entry into such a market is restricted due to high costs or other impediments, which may be economic, social or political. For instance, a government can create a monopoly over an industry that it wants to control, such as electricity. Another reason for the barriers against entry into a monopolistic industry is that oftentimes, one entity has the exclusive rights to a natural resource.
