  • Industrial Policy for National Champions

    Industrial Policy for National Champions

    Oliver Falck, Christian Gollier, and 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.

  • Competitive Failures in Insurance Markets

    Competitive Failures in Insurance Markets

    Theory and Policy Implications

    Pierre-Andre Chiappori and Christian Gollier

    Leading international economists offer new insights on recent developments in the economic analysis of the limits of insurability, with particular attention of adverse selection and moral hazard.

    Risk sharing is a cornerstone of modern economies. It is valuable to risk-averse consumers and essential for investment and entrepreneurs. The standard economic model of risk exchange predicts that competition in insurance markets will result in all individual risks being insured—that all diversifiable risks in the economy will be covered through mutual risk-sharing arrangements—but in practice this is not the case. Many diversifiable risks are still borne by individuals; many environmental, catastrophic, and technological risks are not covered by insurance contracts. In this CESifo volume, leading international economists provide new insights on recent developments in the economic analysis of the limits of insurability. They find that asymmetric information is a central reason why competition in insurance markets may fail to guarantee that mutually advantageous risk exchanges are realized in today's economies. In particular, adverse selection and moral hazard help explain why competitive insurance markets fail to provide an efficient level of insurance and hence why public intervention is required to solve the problem. The contributors offer theoretical models of insurance markets involving adverse selection as well as empirical analyses of health insurance and non-health insurance markets in countries including Australia, Sweden, Switzerland, and the United States.

  • The Economics of Risk and Time

    The Economics of Risk and Time

    Christian Gollier

    This book updates and advances the theory of expected utility as applied to risk analysis and financial decision making. Von Neumann and Morgenstern pioneered the use of expected utility theory in the 1940s, but most utility functions used in financial management are still relatively simplistic and assume a mean-variance world. Taking into account recent advances in the economics of risk and uncertainty, this book focuses on richer applications of expected utility in finance, macroeconomics, and environmental economics.

    The book covers these topics: expected utility theory and related concepts; the standard portfolio problem of choice under uncertainty involving two different assets; P the basic hyperplane separation theorem and log-supermodular functions as technical tools for solving various decision-making problems under uncertainty; s choice involving multiple risks; the Arrow-Debreu portfolio problem; consumption and saving; the equilibrium price of risk and time in an Arrow-Debreu economy; and dynamic models of decision making when a flow of information on future risks is expected over time. The book is appropriate for both students and professionals. Concepts are presented intuitively as well as formally, and the theory is balanced by empirical considerations. Each chapter concludes with a problem set.

  • Global Carbon Pricing

    Global Carbon Pricing

    The Path to Climate Cooperation

    Peter Cramton, David JC MacKay, Axel Ockenfels, and Steven Stoft

    Why the traditional “pledge and review” climate agreements have failed, and how carbon pricing, based on trust and reciprocity, could succeed.

    After twenty-five years of failure, climate negotiations continue to use a “pledge and review” approach: countries pledge (almost anything), subject to (unenforced) review. This approach ignores everything we know about human cooperation. In this book, leading economists describe an alternate model for climate agreements, drawing on the work of the late Nobel laureate Elinor Ostrom and others. They show that a “common commitment” scheme is more effective than an “individual commitment” scheme; the latter depends on altruism while the former involves reciprocity (“we will if you will”).

    The contributors propose that global carbon pricing is the best candidate for a reciprocal common commitment in climate negotiations. Each country would commit to placing charges on carbon emissions sufficient to match an agreed global price formula. The contributors show that carbon pricing would facilitate negotiations and enforcement, improve efficiency and flexibility, and make other climate policies more effective. Additionally, they analyze the failings of the 2015 Paris climate conference.

  • The Continuing Evolution of Europe

    The Continuing Evolution of Europe

    Thiess Buettner and Wolfgang Ochel

    Economists address key challenges facing the EU, including financial instability, welfare state reform, inadequate institutional framework, and global economic integration.

    The European Union began with efforts in the Cold War era to foster economic integration among a few Western European countries. Today's EU constitutes an upper tier of government that affects almost every level of policymaking in each of its twenty-seven member states. The recent financial and economic crises have tested this still-evolving institutional framework, and this book surveys key economic challenges faced by the EU.

    Prominent European economists examine such topics as the stability of the financial markets and possible policy options to reduce future vulnerability to crises, including Glass-Steagull-style narrow banking; the effect of emerging economies such as China and India on Europe's economic position; the protection of national interests in industrial policy; reforming and preserving the welfare state in the face of unemployment, population aging, and worker mobility within the EU; and improving the EU's institutional framework by reassigning responsibilities among supranational, national, and local governments.

    Among the conclusions that emerge from these analyses are the necessity for banking regulation as well as budgetary discipline; the need to consider global as well as European integration; and the idea that an environment that fosters internal competition will increase Europe's competitiveness internationally.

  • Pension Strategies in Europe and the United States

    Pension Strategies in Europe and the United States

    Robert Fenge, Georges de Menil, and Pierre Pestieau

    Leading economists analyze topical issues in pension policy, including structural reform of pay-as-you-go systems, the political sustainability of pension reforms, and the need for private, funded systems.

    Demographic realities will soon force developed countries to find ways to pay for longer retirements for more people. In Pension Strategies in Europe and the United States, leading economists analyze topical issues in pension policy, with a focus on raising the retirement age, increasing retirement savings, and the political sustainability of reforms that will accomplish these goals. After a substantive and wide-ranging introduction by the editors that weaves together the demographic and economic strands of the story, the chapters present cutting-edge research, offering both theoretical and empirical analyses. Contributors examine such topics as the reform of key structural features of existing pay-as-you-go (PAYG) pension systems, analyzing how benefits should vary with the age of retirement, labor supply elasticity after France's 1993 pension reform, and fiscal response to a demographic shock; the feasibility of PAYG reforms in the United States and the competition among state pension systems that results from labor mobility in Europe; and private, funded systems (increasingly perceived as necessary adjuncts to PAYG systems) in the UK, the US, and the Netherlands, and in terms of individual portfolio management. The editors conclude the volume with a study of recent German and UK reforms and their effects on personal savings.
