Diane Coyle — Finance, the state and innovation

Summary:
Yesterday brought the launch of a new and revised edition of Doing Capitalism in the Innovation Economy by William Janeway. Anybody who read the first (2012) edition will recall the theme of the ‘three player game’ – market innovators, speculators and the state – informed by Keynes and Minsky as well as Janeway’s own experience combining an economics PhD with his experience shaping the world of venture capital investment. The term refers to how the complicated interactions between government, providers of finance and capitalists drive technological innovation and economic growth. The overlapping institutions create an inherently fragile system, the book argues – and also a contingent one. Things can easily turn out differently....  Bingo. The fundamental assumption of a free

Bingo.

The fundamental assumption of a free enterprise system ("capitalism") is that entrepreneurship drives innovation, which accelerates growth and overall prosperity.

Looking at the historical record, this is obviously true. But it is more complicated than that, and a lot things can go wrong if all the gears in the machine are not always in sync. History also shows that they are not as evidence by cycles, where all cycles are a combination of business (economic) and financial factors that are influenced by a number of contingencies in a dynamic environment, including policy and its application.

The problem I have with this type of reasoning is that assumes away contingency. Technological innovation land the creation of a consumer society through marketing and advertising lead to the creation of mass markets, which changed the dynamic in a way that models did not anticipate and likely could not have because the new technology that made this possible was emergent and foreseeable in advance.

I don't think that this vitiates Marx and Engels' approach, but rather strengthens the argument for the need for conceptual models that are based on "fuzzy logic" to complement formal modeling based on technically defined analytical concepts and precise measurement to delimit the boundaries of sets.

Contingency implies uncertainty. Uncertainty implies the need to use fuzzy logic rather than the strict formalization that conventional economics as "science" demands. Both are necessary tools, especially as scale increases — which is what the fallacy of composition is about. Macro is not and cannot be scaled up micro analysis.

Of course, what can be formalized usefully should be used. But not everything is capable of being modeled formally in a dynamic way when contingency is involved, and static models are mostly gadgets when cet. par. is assumed.
