This comment on Asada et al.’s paper discusses the contrast between ‘integrated Keynesian disequilibrium dynamics’ (IKDD) and New Keynesian theory. Two areas are singled out: the treatment of stability issues and the approach to behavioral foundations. IKDD present a sophisticated stability analysis and rightly avoid the New Keynesian obsession with microfoundations based on optimizing behavior. The IKDD program, however, might benefit if behavioral questions were given greater prominence.
