This paper looks at the empirical record whether big infrastructure and public capital drives have succeeded in accelerating economic growth in low-income countries. It looks at big long-lasting drives in public capital spending, as these were arguably clear and exogenous policy decisions. On average the evidence shows only a weak positive association between investment spending and growth and only in the same year, as lagged impacts are not significant. Furthermore, there is little evidence of long term positive impacts. Some individual countries may be exceptions to this general result, as for example Ethiopia in recent years, as high public investment has coincided with high GDP growth, but it is probably too early to draw definitive conclusions. The fact that the positive association is largely instantaneous argues for the importance of either reverse causality, as capital spending tends to be cut in slumps and increased in booms, or Keynesian demand effects, as spending boosts output in the short run. It argues against the importance of long term productivity effects, as these are triggered by the completed investments (which take several years) and not by the mere spending on the investments. In fact a slump in growth rather than a boom has followed many public capital drives of the past. Case studies indicate that public investment drives tend eventually to be financed by borrowing and have been plagued by poor analytics at the time investment projects were chosen, incentive problems and interest-group-infested investment choices. These observations suggest that the current public investment drives will be more likely to succeed if governments do not behave as in the past, and instead take analytical issues seriously and safeguard their decision process against interests that distort public investment decisions.

The result of two years work by 19 experienced policymakers and two Nobel prize-winning economists, 'The Growth Report' is the most complete analysis to date of the ingredients which, if used in the right country-specific recipe, can deliver growth and help lift populations out of poverty.

This paper introduces a new index that captures the institutional environment underpinning public investment management across four different stages: project appraisal, selection, implementation, and evaluation. Covering 71 countries, including 40 low-income countries, the index allows for benchmarking across regions and country groups and for nuanced policy-relevant analysis and identification of specific areas where reform efforts could be prioritized. Potential research venues are outlined.

A Financial Times Book of the Year “The strongest documentation I have seen for the many ways in which inequality is harmful to economic growth.” —Jason Furman “A timely and very useful guide...Boushey assimilates a great deal of recent economic research and argues that it amounts to a paradigm shift.” —New Yorker Do we have to choose between equality and prosperity? Decisions made over the past fifty years have created underlying fragilities in our society that make our economy less effective in good times and less resilient to shocks, such as today’s coronavirus pandemic. Many think tackling inequality would require such heavy-handed interference that it would stifle economic growth. But a careful look at the data suggests nothing could be further from the truth—and that reducing inequality is in fact key to delivering future prosperity. Presenting cutting-edge economics with verve, Heather Boushey shows how rising inequality is a drain on talent, ideas, and innovation, leading to a concentration of capital and a damaging under-investment in schools, infrastructure, and other public goods. We know inequality is fueling social unrest. Boushey shows persuasively that it is also a serious drag on growth. “In this outstanding book, Heather Boushey...shows that, beyond a point, inequality damages the economy by limiting the quantity and quality of human capital and skills, blocking access to opportunity, underfunding public services, facilitating predatory rent-seeking, weakening aggregate demand, and increasing reliance on unsustainable credit.” —Martin Wolf, Financial Times “Think rising levels of inequality are just an inevitable outcome of our market-driven economy? Then you should read Boushey’s well-argued, well-documented explanation of why you’re wrong.” —David Rotman, MIT Technology Review

Why do governments in developing economies invest in roads and not enough in schools? In the presence of distortionary taxation and debt aversion, the different pace at which roads and schools contribute to economic growth turns out to be central to this decision. Specifically, while costs are front-loaded for both types of investment, the growth benefits of schools accrue with a delay. To put things in perspective, with a “big push,” even assuming a large (15 percent) return differential in favor of schools, the government would still limit the fraction of the investment scale-up going to schools to about a half. Besides debt aversion, political myopia also turns out to be a crucial determinant of public investment composition. A “big push,” by accelerating growth outcomes, mitigates myopia—but at the expense of greater risks to fiscal and debt sustainability. Tied concessional financing and grants can potentially mitigate the adverse effects of both debt aversion and political myopia.

"Thought provoking and fresh - this book challenges how we think about economics.” Gillian Tett, Financial Times For further information about recent publicity events and media coverage for Rethinking Capitalism please visit http://marianamazzucato.com/rethinking-capitalism/ Western capitalism is in crisis. For decades investment has been falling, living standards have stagnated or declined, and inequality has risen dramatically. Economic policy has neither reformed the financial system nor restored stable growth. Climate change meanwhile poses increasing risks to future prosperity. In this book some of the world’s leading economists propose new ways of thinking about capitalism. In clear and compelling prose, each chapter shows how today’s deep economic problems reflect the inadequacies of orthodox economic theory and the failure of policies informed by it. The chapters examine a range of contemporary economic issues, including fiscal and monetary policy, financial markets and business behaviour, inequality and privatisation, and innovation and environmental change. The authors set out alternative economic approaches which better explain how capitalism works, why it often doesn’t, and how it can be made more innovative, inclusive and sustainable. Outlining a series of far-reaching policy reforms, Rethinking Capitalism offers a powerful challenge to mainstream economic debate, and new ideas to transform it.
