In matching problems, there is no need for any assumptions of how people act; the results are determined regardless of how people behave. Economists do use matching formulas, but never alone as a complete theory. Economic theories always contain assumptions about how people act. But within the theories, matching formulas in the form of identities can play important roles. An identity is a statement true by definition. An example of an identity is the statement, "The amount bought must equal the amount sold." Because whatever is bought must have been sold and vice versa, this statement must always be true. Another example of an identity is the statement "Net worth equals assets minus liabilities." This statement underlies the balance sheet, a basic tool of accounting.

在匹配的问题，也没有任何假设需要人们的行为;的结果是决定不管人们如何表现。经济学家们使用匹配的公式，但从来没有单独作为一个完整的理论。经济理论总是包含有关假设人们的行为。但在理论，匹配的身份形式的公式可以发挥重要作用。
一个身份是一个真正的定义声明。身份的一个例子是说，“这次收购金额必须等于销售量。”因为无论是买必须被出售，反之亦然，这句话必须始终正确的。另一个例子是一个身份的声明“净值等于资产减去负债。”本声明的基础的资产负债表，会计的基本工具。
