Jean-Pascal Bénassy, alongside contemporaries like Edmond Malinvaud and Robert Barro, revolutionized this field by formalizing . He provided the mathematical tools to model an economy where prices do not adjust instantly. In a Bénassy model, agents do not simply trade at market-clearing prices; they face constraints. They cannot sell as much labor as they want, or they cannot buy as many goods as they desire. This framework, often called "Disequilibrium Macroeconomics," offers a rigorous explanation for involuntary unemployment that pure Walrasian theory cannot explain.
