The Economics of Discounting in an Uncertain World

Pricing the Planet's Future

For all of their focus on asset prices, financial economists rarely ask if assets are priced ethically—that is, if their prices are compatible with the public good. Yet in a world facing major, possibly catastrophic problems—global warming, for instance, and growing inequality—it is now more important than ever that we allocate capital to projects that will benefit society as a whole, not just today but far into the future. In this book, Christian Gollier develops a powerful method for transforming our societal goals of collective prosperity into the cornerstone of our financial decision making. Ethical Asset Valuation and the Good Society starts by stating transparent moral principles and, from these, derives simple rules that can be used to evaluate saving and investment decisions in terms of the public good. Rather than trying to explain observed asset prices, Gollier derives what these prices ought to be in order to direct capital toward socially desirable investments. He focuses especially on the two prices that drive most financial decisions—the price of time as reflected in the interest rate and the price of risk—and explores the role these play in our long-term planning. If investment projects in renewable energy could be financed at a lower interest rate than those linked to fossil fuels, for instance, the energy transition would be easier to accomplish. Building on criticism of the short-term thinking of financial markets, Gollier suggests ways to shift investment toward the future through the discounting of the valuation of assets and investments with long-term benefits. In this sophisticated but accessible work, Gollier builds a bridge between welfare economics and finance theory to provide a framework for ethical valuation capable of establishing what asset prices should be on the basis of our shared moral values.

Ethical Asset Valuation and the Good Society

On a longtemps vendu à l'opinion publique l'illusion aujourd'hui hautement inflammable d'une transition écologique merveilleuse, qui créerait emplois et richesses pour tous, tout en redonnant à la nature son lustre d'antan. Cette caverne d'Ali Baba n'existe pas. Au contraire, quoi que l'on fasse, la lutte pour le climat est attentatoire au pouvoir d'achat. Elle nous oblige à nous détourner à moyen terme de cette énergie fossile qui a fait notre fortune pendant deux siècles et à demander aux pays en développement d'en faire autant. Cette guerre pour le climat ne pourra se gagner sans la mobilisation de chacun. Cela nécessite d'appliquer le principe pollueur-payeur, en imposant un prix universel du carbone reflétant la valeur du dommage qu'il génère, quitte à le compenser pour les plus pauvres. Mais les Français sont-ils prêts à sacrifier un peu de leur bien-être aujourd'hui pour améliorer beaucoup le bien-être d'autrui, même si cet autrui n'est essentiellement pas français, et qu'il n'est probablement même pas encore né ? Pour la plupart, ici et ailleurs, la fin du mois passe avant la fin du monde. Ce constat dérangeant pose la question de nos responsabilités envers l'humanité.

An understanding of risk and how to deal with it is an essential part of modern economics. Whether liability litigation for pharmaceutical firms or an individual's having insufficient wealth to retire, risk is something that can be recognized, quantified, analyzed, treated--and incorporated into our decision-making processes. This book represents a concise summary of basic multiperiod decision-making under risk. Its detailed coverage of a broad range of topics is ideally suited for use in advanced undergraduate and introductory graduate courses either as a self-contained text, or the introductory chapters combined with a selection of later chapters can represent core reading in courses on macroeconomics, insurance, portfolio choice, or asset pricing. The authors start with the fundamentals of risk measurement and risk aversion. They then apply these concepts to insurance decisions and portfolio choice in a one-period model. After examining these decisions in their one-period setting, they devote most of the book to a multiperiod context, which adds the long-term perspective most risk management analyses require. Each chapter concludes with a discussion of the relevant literature and a set of problems. The book presents a thoroughly accessible introduction to risk, bridging the gap between the traditionally separate economics and finance literatures.

The Economics of Risk and Time

Oliver Falck

Ludger Woessmann

Prominent economists present the pros and cons of government's subsidizing or protecting firms that are "national champions." Governments around the world are deeply divided about the proper role of industrial policy, with some politicians arguing for hands-off governance and others supporting government intervention to promote "national champions"-- firms that receive government support for both political and economic reasons. In this volume, prominent economists present the pros and cons of government support for national champions. The contributors use the rigor of economic models in their studies, offering a quantitative perspective that complements and extends existing qualitative studies, and focus on issues emerging from the European Union's substantial degree of market integration. Many arguments in favor of champions-promoting policies are made in a dynamic context, so the book first presents chapters that take a dynamic economy view, then presents chapters that examine the political economy of the decision process, and finally, offers "classical" static equilibrium arguments. The richness of the different models provides a deeper understanding of industrial policy than could any model alone. What becomes clear from these different perspectives nevertheless is that it is difficult to make a general case in favor of policies promoting national champions on purely economic grounds and that these policies are best understood in political terms.
