It has been argued that aggregate-supply/aggregate-demand (AS/AD) models suffer from an inconsistency because they assume that firms set price and adjust quantity for the AD curve and are profit-maximizing price takers for the AS curve. It is shown that this inconsistency is rife in intermediate...

Paul Davidson is one the best known and influential Post Keynesian economists alive today. He has insisted throughout his career that economists should focus on real world problems and that the purpose of economic policy is to help society become more humane and civilized. He is also known for...

This paper argues that Keynes's "theory of effective demand" merely restates in outwardly novel aggregative terms ideas that are part and parcel of "classical theory," and so adds nothing of substance to orthodox doctrine. The aim of the paper is to impugn neither The General Theory nor...

Both New Classical and New Keynesian macroeconomic theorists misunderstand and distort old Keynesian economics, alleging that its diagnoses and prescriptions depend on the indefensible assumption that money wages and prices are "rigid." Here it is argued that all Keynesian macro requires is that...

Macroeconomic models incorporating multiple equilibriums are gaining popularity and seem to have a strong intuitive appeal. This paper explains the notion of coordination failure in macroeconomics and introduces the papers in this conference volume. It also addresses sunspot equilibrium theory...

This paper develops a real-exchange production-coordination model in which price-setting firms produce complementary inputs that are converted into and traded for a final good produced by a competitive sector. A rigid real-price regime is shown to be consistent with both rational firm behavior...

As presented in most undergraduate economics textbooks, the aggregate supply/aggregate demand apparatus (AS-AD) is not only logically flawed, which Robert Barro recently demonstrated in this Journal, but seems ideally designed to prevent student learning by concealing the logic that lies behind...

If you reduce a multi-dimensional relationship to a two dimensional graph, you are going to cause some confusion. If you do so without being explicitly clear about the definitions and assumptions you are making in the reduction, you will likely cause significant confusion. The AS/AD labeling...

The current critical discussions of IS-LM/AS-AD models are approached from the perspective of Hicks’ original 1937 SI-LL model. The relevant features of this model are summarized and the geometrical representation of IS and LM curves in the original model and some of its variants is discussed....
