We are always in the disequilibrium state characterized by the unintended increase or decrease of commodity stock, and the involuntary unemployment, etc. What does the economy realize in this disequilibrium state? To answer this question consistently, we formulate a short run macroeconomic model based on several empirical facts findings. The most important fact among others is that the sellers (firms) set the prices and the buyers (consumers), accepting this assigned prices, only adjust how much to buy. The next question is whether such disequilibrium state is stable or not, and it is easily proved that our economy satisfy the stability condition.
