Fiscal policy makers have faced an extraordinarily challenging environment over the last few years. At the outset of the global financial crisis, the IMF for the first time advocated a fiscal expansion across all countries able to afford it, a seeming departure from the long-held consensus among economists that monetary policy rather than fiscal policy was the appropriate response to fluctuations in economic activity. Since then, the IMF has emphasized that the speed of fiscal adjustment should be determined by the specific circumstances in each country. Its recommendation that in general deficit reduction proceed steadily, but gradually, positions the IMF between the fiscal doves (who argue for postponing fiscal adjustment altogether) and the fiscal hawks (who argue for a front-loaded adjustment).

All this is highlighted in a  recently released book Post-Crisis Fiscal Policy, edited by Carlo Cottarelli, Philip Gerson and Abdelhak Senhadji,  that brings together the analysis underpinning the IMF’s position on the evolving role of fiscal policy.  The book underscores how the global financial crisis has reshaped our understanding of the role of fiscal policy with topics that include a historical view of debt accumulation; the timing, size, and composition of fiscal stimulus packages in advanced and emerging economies; the heated debate surrounding the size of fiscal multipliers and the effectiveness of fiscal policy as a countercyclical tool and more.
