In late 2008 a consensus was reached amongst global policymakers that fiscal stimulus was required to counteract the effects of the Great Recession, a view dubbed as the New Fiscalism. Pragmatism triumphed over the stipulations of the New Consensus Macroeconomics, which viewed discretionary fiscal actions as an irrelevant tool of counter-cyclical macroeconomic policy (if not altogether detrimental). The partial re-embrace of Keynes was however relatively short-lived, lasting only until early 2010 when fiscal consolidation came to the forefront again, although the merits of fiscal austerity were questioned when economic recovery did not really materialize in 2012. This paper traces the ups and downs of the debate over the New Fiscalism, especially at the International Monetary Fund, by analysing IMF documents and G20 communiqués. Using fiscal policy as a means to exit the crisis remains contentious even amidst recognition of secular stagnation.

The Influence of Demand on Aggregate Supply
The first question I would like to pose concerns the distinction between aggregate supply and aggregate demand: Are there circumstances in which changes in aggregate demand can have an appreciable, persistent effect on aggregate supply?
Prior to the Great Recession, most economists would probably have answered this question with a qualified “no.” They would have broadly agreed with Robert Solow that economic output over the longer term is primarily driven by supply–the amount of output of goods and services the economy is capable of producing, given its labor and capital resources and existing technologies. Aggregate demand, in contrast, was seen as explaining shorter-term fluctuations around the mostly exogenous supply-determined longer-run trend. This conclusion deserves to be reconsidered in light of the failure of the level of economic activity to return to its pre-recession trend in most advanced economies. This post-crisis experience suggests that changes in aggregate demand may have an appreciable, persistent effect on aggregate supply–that is, on potential output.
The idea that persistent shortfalls in aggregate demand could adversely affect the supply side of the economy–an effect commonly referred to as hysteresis–is not new; for example, the possibility was discussed back in the mid-1980s with regard to the performance of European labor markets.
