Service competition based on service quality and price

The difference between service suppliers' promised service quality and actual service quality markedly influences their demand. Service suppliers compete with each other based on service quality and price, and service quality is expressed by service reliability. Service demand depends on all of the service suppliers' service quality and price in the market. The competition among service suppliers includes three types: 1. Price competition among service suppliers with given service level. There is a unique Nash equilibrium among service suppliers; 2. service quality competition among service suppliers with a fixed price. Every service supplier's optimal decision is not affected by other service suppliers; 3. service quality and price competition among service suppliers. With the objective of maximizing profit, service suppliers make the optimal choice of price, service quality and the corresponding service demand. It shows that service suppliers' different strategies result in different equilibrium behaviors.
