Here’s an excellent article (the first link below) for giving an overview of macroeconomic thinking and policy since the start of the financial crisis in 2007. It looks at how a Keynesian consensus emerged in 2008–9, culminating in policies of fiscal and monetary stimulus being adopted in most major economies.
It also looks at how this consensus broke down from 2010 with the subsequent problem of rising public-sector deficits and debt, and was replaced by a new, although less widespread, consensus of fiscal restraint.
The article is not just about economic theory and policy, but also about the process and politics of how consensus and ‘dissensus’ emerge. It looks at the spread of ideas as a process of ‘contagion’ and how dissent may reflect the view of different defined groups, such as political parties or schools of economic thought.

- What were the features of the Keynesian consensus in 2008–9?
- To what extent can the consensus of that period be described as the result of ‘contagion’?
- Why did consensus break down in 2010?
- How do economic experts play a political role in economic crises?
- To what extent does a lack of consensus benefit politicians?
- Why may the appearance of a consensus be more important in driving policy than actual consensus?
