Worst-case scenarios are all too real, and all too common. The financial crisis of 2008 was not the first or the last to destroy jobs, homeownership and the savings of millions of people. Hurricanes clobber communities from New York to Bangladesh. How bad will the next catastrophe be, and how soon will it happen? Climate and financial crises are serious events, requiring vigorous responses. Yet public policy is trapped in an obsolete framework, with a simplistic focus on average or likely outcomes rather than dangerous extremes. What would it take to create better analyses of extreme events in climate and finance, and an appropriate policy framework for worst-case risks? ‘Worst-Case Economics: Extreme Events in Climate and Finance’ offers accessible and surprising answers to these crucial questions.

Nuclear bombs in suitcases, anthrax bacilli in ventilators, tsunamis and meteors, avian flu, scorchingly hot temperatures: nightmares that were once the plot of Hollywood movies are now frighteningly real possibilities. How can we steer a path between willful inaction and reckless overreaction? Cass Sunstein explores these and other worst-case scenarios and how we might best prevent them in this vivid, illuminating, and highly original analysis. Singling out the problems of terrorism and climate change, Sunstein explores our susceptibility to two opposite and unhelpful reactions: panic and utter neglect. He shows how private individuals and public officials might best respond to low-probability risks of disaster—emphasizing the need to know what we will lose from precautions as well as from inaction. Finally, he offers an understanding of the uses and limits of cost–benefit analysis, especially when current generations are imposing risks on future generations. Throughout, Sunstein uses climate change as a defining case, because it dramatically illustrates the underlying principles. But he also discusses terrorism, depletion of the ozone layer, genetic modification of food, hurricanes, and worst-case scenarios faced in our ordinary lives. Sunstein concludes that if we can avoid the twin dangers of overreaction and apathy, we will be able to ameliorate if not avoid future catastrophes, retaining our sanity as well as scarce resources that can be devoted to more constructive ends.

Introduces exciting new methods for assessing algorithms for problems ranging from clustering to linear programming to neural networks.

Al Qaeda detonates a nuclear weapon in Times Square during rush hour, wiping out half of Manhattan and killing 500,000 people. A virulent strain of bird flu jumps to humans in Thailand, sweeps across Asia, and claims more than fifty million lives. A single freight car of chlorine derails on the outskirts of Los Angeles, spilling its contents and killing seven million. An asteroid ten kilometers wide slams into the Atlantic Ocean, unleashing a tsunami that renders life on the planet as we know it extinct. We consider the few who live in fear of such scenarios to be alarmist or even paranoid. But Worst Cases shows that such individuals—like Cassandra foreseeing the fall of Troy—are more reasonable and prescient than you might think. In this book, Lee Clarke surveys the full range of possible catastrophes that animate and dominate the popular imagination, from toxic spills and terrorism to plane crashes and pandemics. Along the way, he explores how the ubiquity of worst cases in everyday life has rendered them ordinary and mundane. Fear and dread, Clarke argues, have actually become too rare: only when the public has more substantial information and more credible warnings will it take worst cases as seriously as it should. A timely and necessary look into how we think about the unthinkable, Worst Cases will be must reading for anyone attuned to our current climate of threat and fear.

The industrialized world has long been rocked by economic crises, often caused by policy makers who are guided by ideology rather than cold, hard analysis. WRONG examines the worst economic policy blunders of the last 250 years, providing a valuable guide book for policy makers... and the citizens who elect them.

Recognizing that robust decision making is vital in risk management, this book provides concepts and algorithms for computing the best decision in view of the worst-case scenario. The main tool used is minimax, which ensures robust policies with guaranteed optimal performance that will improve further if the worst case is not realized. The applications considered are drawn from finance, but the design and algorithms presented are equally applicable to problems of economic policy, engineering design, and other areas of decision making. Critically, worst-case design addresses not only Armageddon-type uncertainty. Indeed, the determination of the worst case becomes nontrivial when faced with numerous--possibly infinite--and reasonably likely rival scenarios. Optimality does not depend on any single scenario but on all the scenarios under consideration. Worst-case optimal decisions provide guaranteed optimal performance for systems operating within the specified scenario range indicating the uncertainty. The noninferiority of minimax solutions--which also offer the possibility of multiple maxima--ensures this optimality. Worst-case design is not intended to necessarily replace expected value optimization when the underlying uncertainty is stochastic. However, wise decision making requires the justification of policies based on expected value optimization in view of the worst-case scenario. Conversely, the cost of the assured performance provided by robust worst-case decision making needs to be evaluated relative to optimal expected values. Written for postgraduate students and researchers engaged in optimization, engineering design, economics, and finance, this book will also be invaluable to practitioners in risk management.

In Austerity: The History of a Dangerous Idea, Mark Blyth, a renowned scholar of political economy, provides a powerful and trenchant account of the shift toward austerity policies by governments throughout the world since 2009. The issue is at the crux about how to emerge from the Great Recession, and will drive the debate for the foreseeable future.

An empirical investigation of financial crises during the last 800 years.

According to many scientists, climate change is a growing threat to life as we know it, requiring a large-scale, immediate response. According to many economists, climate change is a moderately important problem; the best policy is a slow, gradual start, to avoid spending too much. They can't both be right. In this book, Frank Ackerman offers a refreshing look at the economics of climate change, explaining how the arbitrary assumptions of conventional theories get in the way of understanding this urgent problem. The benefits of climate protection are vital but priceless, and hence often devalued in cost-benefit calculations. Preparation for the most predictable outcomes of global warming is less important than protection against the growing risk of catastrophic change; massive investment in new, low carbon technologies and industries should be thought of as life insurance for the planet. Ackerman makes an impassioned plea to construct a better economics, arguing that the solutions are affordable and the alternative is unthinkable. If we can't afford the future, what are we saving our money for? Can we Afford the Future? is part of The New Economics series, which uses the ideas behind a new, more human economics to provide a fresh way of looking at major contemporary issues.

In the graveyard of economic ideology, dead ideas still stalk the land. The recent financial crisis laid bare many of the assumptions behind market liberalism—the theory that market-based solutions are always best, regardless of the problem. For decades, their advocates dominated mainstream economics, and their influence created a system where an unthinking faith in markets led many to view speculative investments as fundamentally safe. The crisis seemed to have killed off these ideas, but they still live on in the minds of many—members of the public, commentators, politicians, economists, and even those charged with cleaning up the mess. In Zombie Economics, John Quiggin explains how these dead ideas still walk among us—and why we must find a way to kill them once and for all if we are to avoid an even bigger financial crisis in the future. Zombie Economics takes the reader through the origins, consequences, and implosion of a system of ideas whose time has come and gone. These beliefs—that deregulation had conquered the financial cycle, that markets were always the best judge of value, that policies designed to benefit the rich made everyone better off—brought us to the brink of disaster once before, and their persistent hold on many threatens to do so again. Because these ideas will never die unless there is an alternative, Zombie Economics also looks ahead at what could replace market liberalism, arguing that a simple return to traditional Keynesian economics and the politics of the welfare state will not be enough—either to kill dead ideas, or prevent future crises. In a new chapter, Quiggin brings the book up to date with a discussion of the re-emergence of pre-Keynesian ideas about austerity and balanced budgets as a response to recession.
