This paper applies quasi-static analysis to a simple closed macroeconomy. It is shown that if the economy satisfies a conservation of income requirement, and the requirement that all equivalent investments generate the same rate of return (non- arbitrage), then there exists a state variable which measures the opportunity cost of moving from one macroeconomic equilibrium to another. This state variable is an economic constraint which measures the expenditure necessary to change equilibria. Central to this analysis is a definition of economic time, which is an invariant quantity with respect to the state variables used as a frame of reference.
本文将准静态分析应用于一个简单的封闭宏观经济。结果表明，如果经济满足收入守恒的要求，且所有等价投资产生相同的收益率(无套利)，则存在一个状态变量，该状态变量度量从一个宏观经济均衡到另一个宏观经济均衡的机会成本。这个状态变量是一个经济约束，用来衡量改变均衡所需的支出。这一分析的中心是经济时间的定义，它是相对于作为参照系的状态变量的一个不变的量。
