Final answer:
The minimum concession acceptable by a party in a negotiation is known as the break-even point. This is the least favorable point at which a party will agree to a deal, ensuring no loss is incurred. In economics, it also refers to the level of output where a company neither makes a profit nor a loss.
Step-by-step explanation:
The term you are looking for is break-even point. In negotiations, particularly in business contexts, this term refers to the minimum outcome a party is willing to accept without making a loss. While in economics, the break-even point is a level of output at which a company's revenue is equal to its total costs, resulting in zero economic profit. In negotiating terms, reaching a break-even point means the negotiation outcomes cover all of one's costs or minimum expectations, ensuring that there is no loss involved in agreeing to a deal.
This concept is similarly applied in other areas such as consumer behavior, where a consumer equilibrium is reached when the consumer gains the most satisfaction for their budget, aligning the ratio of prices to the ratio of marginal utilities. In the context of long-run economic performance, this concept also touches upon industry dynamics where entry and exit of firms are determined by the ability to at least break even in the long term.
