Abstract

A significant acceleration in investment is essential if emerging market and developing economies (EMDEs) are to achieve key development goals and tackle the challenges associated with climate change. Investment—public as well as private—tends to fuel a virtuous cycle of development, boosting growth, improving productivity, and reducing poverty. In EMDEs, however, investment growth has seen a sustained slowdown since the global financial crisis and is expected to remain weak in the coming years. Policy action is necessary to reverse this trend. Public investment averages about one-quarter of total investment in the median EMDE—a modest share. Yet it can be a powerful policy lever to help ignite growth, including by helping to catalyze private investment. This webinar presents the main findings of our recent study on the macroeconomic effects of public investment in EMDEs. We report that public investment in these economies has experienced a historic slowdown in the past decade. In EMDEs with ample fiscal space and a record of efficient government spending, on average, scaling up of public investment by one percent of GDP can increase output by up to 1.6 percent over five years. Public investment also crowds in private investment and boosts productivity, promoting long-run economic growth in these economies. To maximize the impact of public investment, EMDEs should undertake wide-ranging policy reforms to improve public investment efficiency—by, among other things, strengthening governance and fiscal administration—and create fiscal space through revenue and expenditure measures. The global community can play an important role in facilitating these reforms—particularly in lower-income developing countries— through financial support and technical assistance.
