We have spent the last three decades engaged in a pointless and irrelevant debate about the relative merits of privatization or nationalization. We have been arguing about the wrong thing while sitting on a goldmine of assets. Don’t worry about who owns those assets, worry about whether they are managed effectively. Why does this matter? Because despite the Thatcher/ Reagan economic revolution, the largest pool of wealth in the world – a global total that is much larger than the world’s total pensions savings, and ten times the total of all the sovereign wealth funds on the planet – is still comprised of commercial assets that are held in public ownership. If professionally managed, they could generate an annual yield of 2.7 trillion dollars, more than current global spending on infrastructure: transport, power, water, and communications. Based on both economic research and hands-on experience from many countries, the authors argue that publicly owned commercial assets need to be taken out of the direct and distorting control of politicians and placed under professional management in a ‘National Wealth Fund’ or its local government equivalent. Such a move would trigger much-needed structural reforms in national economies, thus resurrect strained government finances, bolster ailing economic growth, and improve the fabric of democratic institutions. This radical, reforming book was named one of the "Books of the Year".by both the FT and The Economist.

The book covers a wide range of topics of relevance to policymakers in countries that have sovereign wealth funds (SWFs) and those that receive SWF investments. Renowned experts in the field have contributed chapters. The book is organized around four themes: (1) the role and macrofinancial linkages of SWFs, (2) institutional factors, (3) investment approaches and financial markets, and (4) the postcrisis outlook. The book also discusses the challenges facing sovereign wealth funds in the coming years, from an inside perspective on countries, including Canada, Chile, China, Norway, Russia, and New Zealand. Economics of Sovereign Wealth Funds will contribute to a further understanding of the nature, strategies and behavior of SWFs and the environment in which they operate, as their importance is likely to grow in the coming years.

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.
