"Macroeconomics" builds a number of macroeconomic models applying the non-Walrasian methodology. The literature on the subject has grown so rapidly in recent years that it would be unreasonable to try to give an exhaustive account of all existing models in the field. We have thus chosen to present here some models that cover as large a number of questions as possible within a simple and unified framework. We also want to bridge the gap with traditional macroeconomics while extending the analysis on various points, which be investigated by purposely making each time the simplest possible assumptions about the formation of the various prices (or, when needed, expectations) involved. This will allow us to demonstrate in a straightforward manner the synthetic qualities of the theory, both by making a natural synthesis with traditional macroeconomics, where similar simple assumptions are made, and by treating a large number of topics while using throughout a very unified macroframework.
