I haven't read Phil's majority yet but it looks interesting. He explored a lot of the issues at his blog, Fixing the Economists, which has been inactive for about time.

The Reformation inwards Economics is a majority written past times the Irish Gaelic economist Philip Pilkington. It is a majority that aims to deconstruct contemporary neoclassical economical theory inwards club to decide to what extent it is scientific together with to what extent it is ideological. The majority is divided into iii sections: Ideology together with Methodology, Stripped-Down Macroeconomics together with Approaching the Real World. The kickoff department of the majority engages inwards a deconstruction of economical theory that seeks to weed out the ideological elements of economical theory field introducing a coherent methodology that allows for the reconstruction that follows. The minute department lays out a theory of the macroeconomy that builds on the methodology described inwards the kickoff department together with tackles: money, prices, profits, income distribution, income determination, investment together with finance. The in conclusion department sketches out how such a theory should live on applied to real-world empirical data, with a detail emphasis on the fact that working economists are faced with cardinal dubiety together with then applying their theories is non every bit elementary or straightforward every bit applying theories inwards the difficult sciences, similar physics.…

Pilkington argues that economic science together with whatever disciplines that bargain with historical information rather than repeatable controlled experiments bargain with textile that is fundamentally uncertain. Such textile tin never live on assumed to adhere to fixed laws inwards the means that, say, chemical scientific discipline together with physics tin live on idea to adhere to fixed laws. Neoclassical economists together with econometricians evade this past times claiming that economical together with historical processes are characterised past times known probability distributions. But Pilkington shows that this is impossible because economical together with historical processes are open, non unopen systems together with then rather than dealing with a serial of bounded probabilities nosotros inwards fact bargain with a serial of unbounded possibilities.

The writer lays out about guidelines for how such textile should together with should non live on dealt with inwards both theory together with inwards practice. He highlights the British economist Wynne Godley's approach which he refers to every bit the "unsustainable processes" approach every bit a new together with robust means to bargain with uncertain, opened upwardly systems material. This methodology seeks to locate economical processes that are unsustainable then that the economist tin brand a prediction that they volition come upwardly to an end. Such an approach is non forecasting, every bit no exact appointment is given together with no attempt at predicting specific variables is undertaken. Pilkington argues that this is the best approach to such opened upwardly systems material.

In improver to these wide themes, a skilful bargain of the majority is concerned with laying out an alternative, "stripped-down" theory of the macroeconomy. This theory rests of the kaleidostatics approach of the British economist G.L.S. Shackle. Pilkington formulates much of this theory inwards mathematical terms but does then inwards such a means that it remains an opened upwardly systems approach. The theory that results is closely linked to the Post-Keynesian schoolhouse of economical thought.

Economics should live on approached inwards the same vein every bit military machine strategy together with draw concern planning, taking contingency every bit foundational together with distinguishing alongside known knowns, unknown knowns (implicit knowledge), known unknowns together with unknown unknowns. This requires learning together with adjusting based on feedback — reflexivity, adaptability together with agility inwards answer to emergence.

Conventional economical theory largely presumes the kickoff but non on the solid position down of information but rather intuition together with introspection. Policy makers buy the farm on on the solid position down of ideology rather than knowledge, which is a recipe for defeat inwards military machine strategy together with failure inwards draw concern planning.
