This volumes examines the interaction of labour market conditions and retirement decisions. Based on French and US data, it provides empirical evidence and quantitative analysis of retirement and labor market flows. It studies the horizon effect and uses French individual data and probit models to show that the horizon effect does matter for the probability of being employed before the early retirement age. It analyses the influence of the retirement age on labour-market equilibrium, as well as the impact of labour market conditions, especially the importance of unemployment risk, on retirement decisions.

Setting the issue "Most economists consider the marked increase in automatic stabilizers a highly favorable development with respect to maintenance of economic stability". Besides the rare privilege of having being signed by both Milton Friedman and Paul Samuelson (Depres,Friedman, Hart, Samuelson, and Wallace [1950]), among others, this sentence expressed as soon as 1950 the consensus view on the stabilizing effect of fiscal rules governing tax revenue and public expendi tures and transfers. This positive ex ante assessment will have been confirmed ex post as part of the explanation for post war stabilization (Burns [1960], de Long and Summers [1986], Moore and Zarnovitz [1986]). However, it becomes disputed in both its positive and normative aspects. Many institutional changes since the eighties point at curbing back the transfer mechanisms underlying automatic stabilizers, and legal restraints on deficits such as the US balanced budget amendment or the European Maastricht criteria would involve serious risks for the future of stabilizers. Under such rules "the government would become, almost inevitally, a destabilizer rather than a stabilizer" said Joseph Stiglitz, quoted by the New York Times (April 1995)). "Built-in stabilizers are automatic fiscal adjustments that reduce the national income multiplier and thus cushion the effects of changes in autonomous spend ing on the level of income" (Pechman [1987]). Early analyses of the automatic fiscal stabilizers include the contributions of A. G. Hart [1945], R. Musgrave and M. Miller (1948) and E. C. Brown (1955).

Market Imperfections and Macroeconomic Dynamics is based upon a collection of papers originally presented at the 5th Theory and Methods in Macroeconomics (T2M) meeting in Paris, France, 2002. The contributions in this volume focus on a central theme: the aggregate dynamic consequences of market imperfections. Such effects are of great interest to researchers in macroeconomics as these imperfections play a primary role in the persistence of aggregate output, the characteristics of the business cycles and the interactions of agents over time. Incorporating up-to-date techniques and methods, these contributions exemplify the remarkable progress made by macroeconomists in tackling these issues.
The primary market for Market Imperfections and Macroeconomic Dynamics is academic researchers in economics and graduate students specializing in macroeconomics. Divisions of economic studies in public administration and in financial organizations will also find this book beneficial.
