Welfare economics, scope and performance of government, externalities, public goods, cost-benefit analysis, subsidies economize on spending without losing effectiveness by modifying the conceptual framework guiding state expenditures. The familiar framework says that state intervention is justified when the spending provides public goods or when the intervention addresses externalities, provided the social return is above a threshold. This paper argues that another consideration needs to be brought into the mix - whether, in spite of the externalities, the private sector has an incentive to undertake the activity. It is argued that these two considerations together define a more efficient framework under which to justify state intervention. According to this modified framework, even a benign state interested in social welfare would not in fact address every externality nor necessarily select expenditures with the highest social returns. These points are summarized in a graph which is then used to analyze policy rules, subsidies and effective interaction between the state and the private sector. It is hoped that this paper points to the kind of information that needs to be collected and acted upon so that states may achieve their goals more effectively.

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.

Public investment, and particularly infrastructure investment, is important for sustainable economic growth and development as well as public service provision. However, it is also vulnerable to capture and corruption.

Social Value Investing presents a new way to approach some of society’s most difficult and intractable challenges. Although many of our world’s problems may seem too great and too complex to solve — inequality, climate change, affordable housing, corruption, healthcare, food insecurity — solutions to these challenges do exist, and will be found through new partnerships bringing together leaders from the public, private, and philanthropic sectors. In their new book, Howard W. Buffett and William B. Eimicke present a five-point management framework for developing and measuring the success of such partnerships. Inspired by value investing — one of history’s most successful investment paradigms — this framework provides tools to maximize collaborative efficiency and positive social impact, so that major public programs can deliver innovative, inclusive, and long-lasting solutions. It also offers practical insights for any private sector CEO, public sector administrator, or nonprofit manager hoping to build successful cross-sector collaborations. Social Value Investing tells the compelling stories of cross-sector partnerships from around the world — Central Park and the High Line in New York City, community-led economic development in Afghanistan, and improved public services in cities across Brazil. Drawing on lessons and observations from a broad selections of collaborations, this book combines real life stories with detailed analysis, resulting in a blueprint for effective, sustainable partnerships that serve the public interest. Readers also gain access to original, academic case material and professionally produced video documentaries for every major partnerships profiled — bringing to life the people and stories in a way that few other business or management books have done.

The first two decades of the twenty-first century have witnessed an influx of innovations and reforms in public financial management. The current wave of reforms is markedly different from those in the past, owing to the sheer number of innovations, their widespread adoption, and the sense that they add up to a fundamental change in the way governments manage public money. This book takes stock of the most important innovations that have emerged over the past two decades, including fiscal responsibility legislation, fiscal rules, medium-term budget frameworks, fiscal councils, fiscal risk management techniques, performance budgeting, and accrual reporting and accounting. Not merely a handbook or manual describing practices in the field, the volume instead poses critical questions about innovations; the issues and challenges that have appeared along the way, including those associated with the global economic crisis; and how the ground can be prepared for the next generation of public financial management reforms.

The 2007–09 international financial crisis underscored the importance of reliable and timely statistics on the general government and public sectors. Government finance statistics are a basis for fiscal analysis and they play a vital role in developing and monitoring sound fiscal programs and in conducting surveillance of economic policies. The Government Finance Statistics Manual 2014 represents a major step forward in clarifying the standards for compiling and presenting fiscal statistics and strengthens the worldwide effort to improve public sector reporting and transparency.

We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.
