Four main changes to the core model are recommended: to emphasize financial frictions, to place a limit on the operation of rational expectations, to include heterogeneous agents, and to devise more appropriate microfoundations.

Achieving these objectives requires changes to all of the behavioural equations in the model governing consumption, investment, and price setting, and also the insertion of a wedge between the interest rate set by policymakers and that facing consumers and investors. In our view, the result will not be a paradigm shift, but an evolution towards a more pluralist discipline.
