A la poursuite du Graal : le successeur d'IS-LM est-il identifié ?

On commence à deviner les contours du successeur de IS-LM; la démarche à suivre comme la nature de l’objectif à atteindre sont aujourd’hui relativement claires. À l’aide de trois expériences spécifiques, on déduit quelques-uns des ingrédients susceptibles de faire partie de la nouvelle synthèse néo-classique. Au bout du compte, il apparaît que seule notre connaissance imparfaite de quelques faits stylisés essentiels nous tient éloigné d’un nouveau consensus.The profile of the successor to the IS-LM model starts to emerge; the identifying process and the nature of the objective one is groping for are now relatively clear. With the help of three specific experiments, a few of the likely ingredients of the new neo-classical synthesis are derived. In the end, it appears that only our imperfect knowledge of some key empirical facts keeps us away from a new consensus

How risk averse are fund managers? Evidence from Irish mutual funds

Employing a mean-variance framework and a multivariate GARCH model, the degree of risk aversion exhibited by Irish fund managers is estimated. Managers whose remit is 'aggressive' or 'balanced' management of their portfolios have coefficients lying between 1.69-2.42 and 3.24-3.69 respectively.

Macroeconomic Frictions : What have we learned from the Real Business Cycle research programme ?

One interpretation of the RBC research program is that it was meant to identify and incorporate into dynamic general equilibrium models those market imperfections which are most relevant for macroeconomic theory and policy. This paper reviews the methodological basis for this interpretation. It then discusses the empirical foundations for some of the many frictions that have found their way into RBC models including efficiency wages, labour contracts, nominal price rigidities, limited market participation, imperfect competition and expectational errors. We find that the ?necessity? of these frictions is better established in some cases than in others. While one is lead to the prediction that the ?next neo-classical synthesis? will be a dynamic stochastic general equilibrium with frictions, it is premature to decide which specific friction will necessarily be taken on board
