  • Optimal Pricing, Inflation, and the Cost of Price Adjustment

    Optimal Pricing, Inflation, and the Cost of Price Adjustment

    Eytan Sheshinski and Yoram Weiss

    These collected articles constitute what is perhaps the definitive study of pricing models under inflation, providing a solid basis for further research on this elusive question.

    What are the real effects of inflation? These collected articles constitute what is perhaps the definitive study of pricing models under inflation, providing a solid basis for further research on this elusive question. Covering a broad range of theory and applications by well-known microeconomists, the eighteen contributions evaluate the effects of inflation on aggregate output and on welfare and reveal the scope of recent efforts to explicitly incorporate frictions in economic models. A basic building block common to most of the essays in this volume is the observation that individual firms change nominal prices intermittently. The frequency and size of nominal price changes are influenced by the cost of price adjustment and changes in the economic environment, production costs, market demand, market structure, and most important, inflation. Thus the degree of nominal rigidity is influenced by the economic environment, and in a dynamic context. Two introductory essays survey the empirical studies of pricing policies by individual firms and the theoretical efforts to integrate the nominal rigidities at the micro level into macro relationships. The essays that follow treat the general problem of optimal dynamic adjustment in the presence of convex costs of adjustment, include applications of the inventory models to the case of nominal price adjustment by an individual firm, address the question of aggregation, introduce active search by consumers, and provide empirical analysis of nominal price rigidities.

  • 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.
