There are often blanket claims that the world is facing more problems than ever but there is a lack of empirical data to show where things have deteriorated or in fact improved. In this book, some of the world's leading economists discuss ten problems that have blighted human development, ranging from malnutrition, education, and climate change, to trade barriers and armed conflicts. Costs of the problems are quantified in percent of GDP, giving readers a unique opportunity to understand the development of each problem over the past century and the likely development into the middle of this century, and to compare the size of the challenges. For example: how bad was air pollution in 1900? How has it deteriorated and what about the future? Did climate change cost more than malnutrition in 2010? This pioneering initiative to provide answers to many of these questions will undoubtedly spark debate amongst a wide readership.

In this book leading economists evaluate how the world can best spend money to combat the world's biggest problems.

Edited by Bjørn Lomborg, this abridged version of the highly acclaimed Global Crises, Global Solutions provides a serious yet accessible springboard for debate and discussion on the world's most serious problems, and what we can do to solve them. In a world fraught with problems and challenges, we need to gauge how to achieve the greatest good with our money. This unique book provides a rich set of dialogs examining ten of the most serious challenges facing the world today: climate change, the spread of communicable diseases, conflicts and arms proliferation, access to education, financial instability, governance and corruption, malnutrition and hunger, migration, sanitation and access to clean water, and subsidies and trade barriers. Each problem is introduced by a world-renowned expert who defines the scale of the issue and examines a range of policy options.

Bjørn Lomborg invites leading economists to provide an innovative 150-year view of humanity's biggest challenges, measured in economic terms.

The emergence of severe acute respiratory syndrome (SARS) in late 2002 and 2003 challenged the global public health community to confront a novel epidemic that spread rapidly from its origins in southern China until it had reached more than 25 other countries within a matter of months. In addition to the number of patients infected with the SARS virus, the disease had profound economic and political repercussions in many of the affected regions. Recent reports of isolated new SARS cases and a fear that the disease could reemerge and spread have put public health officials on high alert for any indications of possible new outbreaks. This report examines the response to SARS by public health systems in individual countries, the biology of the SARS coronavirus and related coronaviruses in animals, the economic and political fallout of the SARS epidemic, quarantine law and other public health measures that apply to combating infectious diseases, and the role of international organizations and scientific cooperation in halting the spread of SARS. The report provides an illuminating survey of findings from the epidemic, along with an assessment of what might be needed in order to contain any future outbreaks of SARS or other emerging infections.

The world has many pressing problems. Thanks to the efforts of governments, NGOs, and individual activists there is no shortage of ideas for resolving them. However, even if all governments were willing to spend more money on solving the problems, we cannot do it all at once. We have to prioritize; and in order to do this we need a better sense of the costs and benefits of each 'solution'. This book offers a rigorous overview of twenty-three of the world's biggest problems relating to the environment, governance, economics, and health and population. Leading economists provide a short survey of the analysis and sketch out policy solutions for which they provide cost-benefit ratios. A unique feature is the provision of freely downloadable software which allows readers to make their own cost-benefit calculations for spending money to make the world a better place.
