This chapter discusses various past and future aspects of the global economy. There has been a huge transformation of the global economy in the last several years. Articles on the future of energy in the global economy by Jeffrey Ball and on measuring inequality by Jonathan Ostry and Andrew Berg are also illustrated. Since the 2008 global crisis, global economists must change the way they look at the world.

This paper reviews the theoretical and empirical literature on the effectiveness of fiscal policy. The focus is on the size of fiscal multipliers, and on the possibility that multipliers can turn negative (i.e., that fiscal contractions can be expansionary). The paper concludes that fiscal multipliers are overwhelmingly positive but small. However, there is some evidence of negative fiscal multipliers.

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

This broad survey of unemployment will be a major source of reference for both scholars and students.

The recent recession has brought fiscal policy back to the forefront, with economists and policy makers struggling to reach a consensus on highly political issues like tax rates and government spending. At the heart of the debate are fiscal multipliers, whose size and sensitivity determine the power of such policies to influence economic growth. Fiscal Policy after the Financial Crisis focuses on the effects of fiscal stimuli and increased government spending, with contributions that consider the measurement of the multiplier effect and its size. In the face of uncertainty over the sustainability of recent economic policies, further contributions to this volume discuss the merits of alternate means of debt reduction through decreased government spending or increased taxes. A final section examines how the short-term political forces driving fiscal policy might be balanced with aspects of the long-term planning governing monetary policy. A direct intervention in timely debates, Fiscal Policy after the Financial Crisis offers invaluable insights about various responses to the recent financial crisis.
