Don Patinkin in the context of "Pigou effect"

Disequilibrium macroeconomics is a tradition of research centered on the role of deviation from equilibrium in economics. This approach is also known as non-Walrasian theory, equilibrium with rationing, the non-market clearing approach, and non-tâtonnement theory. Early work in the area was done by Don Patinkin, Robert W. Clower, and Axel Leijonhufvud. Their work was formalized into general disequilibrium models, which were very influential in the 1970s. American economists had mostly abandoned these models by the late 1970s, but French economists continued work in the tradition and developed fixprice models. Other approaches that focus on the dynamic processes and interactions in economic systems that are constantly changing and do not necessarily settle into a stable state are discussed as non-equilibrium economics.
