This is Part 2 of my Three Part exposition of how the standard New Keynesian approach to the specification of fiscal rules will generate poor advice for politicians desiring to achieve progressive socio-economic goals. The paper I am using to represent the New Keynesian approach has, by all indications, been somewhat influential in the formation of the macroeconomic approach currently being espoused by the British Labour Party. In that sense, the critique aims to disabuse the Labour politicians and their apparatchiks of building policy options based on fake economic knowledge, and, instead, embrace the principles of Modern Monetary Theory (MMT), which provides an accurate depiction of how the monetary system actually operates and the policy options for a currency-issuing government such as in Britain, and the likely consequences of deploying these options. The one major lesson that comes out is that the New Keynesian approach is an elaborate fraud. It plays around with so-called ‘optimising’ models asserting human behaviour that no other social scientist believes remotely captures the essence of human decision-making, and then derives conclusions from these models that are claimed to apply to the world we live in. Prior to the GFC, these ‘models’ didn’t even consider the financial sector. The fact is that nothing of value in terms of specifying what a government should do can be gleaned from a New Keynesian approach. It is barren.
