This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.

A New York Times Bestseller The leading thinker and most visible public advocate of modern monetary theory -- the freshest and most important idea about economics in decades -- delivers a radically different, bold, new understanding for how to build a just and prosperous society. Stephanie Kelton's brilliant exploration of modern monetary theory (MMT) dramatically changes our understanding of how we can best deal with crucial issues ranging from poverty and inequality to creating jobs, expanding health care coverage, climate change, and building resilient infrastructure. Any ambitious proposal, however, inevitably runs into the buzz saw of how to find the money to pay for it, rooted in myths about deficits that are hobbling us as a country. Kelton busts through the myths that prevent us from taking action: that the federal government should budget like a household, that deficits will harm the next generation, crowd out private investment, and undermine long-term growth, and that entitlements are propelling us toward a grave fiscal crisis. MMT, as Kelton shows, shifts the terrain from narrow budgetary questions to one of broader economic and social benefits. With its important new ways of understanding money, taxes, and the critical role of deficit spending, MMT redefines how to responsibly use our resources so that we can maximize our potential as a society. MMT gives us the power to imagine a new politics and a new economy and move from a narrative of scarcity to one of opportunity.

Ten case studies suggest that two unorthodox methods of deficit financing - inflation tax and financial repression - are both ineffective in raising revenue and disruptive of macroeconomic stability. Fiscal stabilization leads to both higher private consumption and increased investment and to external adjustment - characterized by a lower trade deficit and a depreciated real exchange rate.
