Final answer:
An efficient consumer response system is an inventory management system designed to optimize the process of restocking and product receipt, facilitating better overall market efficiency.
Step-by-step explanation:
An efficient consumer response system is an inventory management system that is designed to make the process of reordering and receiving products as simple as possible. The core idea behind such a system is to improve the efficiency in the demand and supply model of a business, ensuring the economy gets maximum benefit from its scarce resources, and all possible gains from trade are achieved.
Within this framework, concepts like consumer surplus, producer surplus, and social surplus play a significant role in assessing market efficiency. For example, considering a market for tablet computers, where equilibrium is achieved at a price that reflects both consumer willingness to pay and producer costs, the demand curve illustrates consumer surplus as the area where consumers would have been willing to pay more than the equilibrium price.
