How should firms decide whether and when to invest in new capital equipment, additions to their workforce, or the development of new products? Why have traditional economic models of investment failed to explain the behavior of investment spending in the United States and other countries? In this book, Avinash Dixit and Robert Pindyck provide the first detailed exposition of a new theoretical approach to the capital investment decisions of firms, stressing the irreversibility of most investment decisions, and the ongoing uncertainty of the economic environment in which these decisions are made. In so doing, they answer important questions about investment decisions and the behavior of investment spending.

This new approach to investment recognizes the option value of waiting for better (but never complete) information. It exploits an analogy with the theory of options in financial markets, which permits a much richer dynamic framework than was possible with the traditional theory of investment. The authors present the new theory in a clear and systematic way, and consolidate, synthesize, and extend the various strands of research that have come out of the theory. Their book shows the importance of the theory for understanding investment behavior of firms; develops the implications of this theory for industry dynamics and for government policy concerning investment; and shows how the theory can be applied to specific industries and to a wide variety of business problems.

Most people would probably agree on what should be done to avert severe climate change: The world must reduce CO2 emissions as much and as quickly as possible. But we must also ask what will be done. Is it realistic to expect worldwide emissions to fall rapidly enough to prevent severe climate change? And if we conclude it is not realistic, and so higher temperatures and rising sea levels are likely, what should we do? What actions should we take now to reduce the likely impact of climate change? Whatever climate policies are adopted, there will be a great deal of uncertainty over what will happen as a result. In Climate Future, Robert Pindyck, an authority on the economics of climate change and global catastrophes, explains what we know and what we don't know about the extent of climate change and its impact, why there is so much uncertainty, and what it means for climate policy. This book shows that given the economic and political realities, it is simply not realistic to expect emission reductions needed to avert substantial global warming. Pindyck argues that investments in adaptation-developing new hybrid crops, discouraging building in flood-prone or wildfire-prone areas, building sea walls and dikes, and geoengineering-are needed to insure against catastrophic climate change events. We should invest now in adaptation, and Pindyck shows how that can be done.
