When he edited the first Post Keynesian Guide, Alfred Eichner (1978) was convinced that economics needed a paradigm shift. He was very critical of neoclassical economics, believing that it lacked empirical content and perpetuated a myth that the market is a self-regulating mechanism. He also believed that Post Keynesian economics provided a serious alternative to neoclassical theory. However, he was not optimistic that mainstream economics would accept the Post Keynesian paradigm.
