Summary

Full Text

Fiscal policy has recently gained prominence, both in public debate and in governments’ policy. A reassessment of fiscal policy is taking place, stressing its greater role in fostering sustainable and inclusive growth and smoothing the economic cycle. At the same time, the high uncertainty surrounding the outlook and high levels of public debt require a better understanding and managing of fiscal risks. Therefore, fiscal policy has the difficult task of achieving more and better in a more constrained environment. This issue of the Fiscal Monitor shows how the evolution of the debate on fiscal policy can shed new light on fiscal developments and help frame policy recommendations to countries.

Chapter 1 : A Greater Role for Fiscal Policy

Full Text Blog

The global economy is undergoing major transformations, including a productivity slowdown, technological change, and global economic integration. This creates new demands for public policies to facilitate these transformations, while cushioning the effect on those negatively affected. Fiscal policy has a greater role to play in fostering sustainable and inclusive growth. At the same time, the high degree of uncertainty surrounding the outlook as well as stretched government balance sheets require a better understanding and management of risks. Fiscal policy therefore has the difficult task of achieving more and better in a more constrained environment.

Chapter 2 : Upgrading the Tax System to Boost Productivity

Full Text Blog

A top challenge facing policymakers today is how to raise total factor productivity, the key driver of living standards over the long term. Tackling this challenge calls for the use of all policy levers, and in particular growth-friendly fiscal policies. This chapter makes the case that upgrading a country’s tax system is important to boosting productivity because it can reduce distortions that prevent resources from going to where they are most productive. The chapter offers several key findings to support the overall message that how governments tax matters for productivity. Improving the design of tax policies helps remove the distortions that are holding more productive firms back, generating a positive impact on aggregate productivity and growth.
