Abstract

[spa] Subsidio intertemporal del consumo, desarrollos recientes, . por Jerome Adda.. . Este artículo presenta los desarrollos recientes de la teoría del reparto intertemporal del consumo y del ahorro. Partimos del modelo de ingreso permanente de anticipaciones racionales. Este modelo no permite dar cuenta de la poca volatilidad del consumo con respecto al ingreso o la sensibilidad excesiva a las variaciones del ingreso corriente. Los desarrollos recientes han introducido entonces varias extensiones. El estudio de comportamientos prudentes permite estudiar el ahorro de precaución, así como tomar en cuenta mejor los efectos del riesgo sobre el consumo. Las restricciones de liquidez permiten explicar la relación entre consumo e ingreso corriente. Por último, el estudio de funciones de utilidad que no pueden ser separadas en el tiempo permite explicar la persistencia del consumo y modelizar las costumbres de consumo o la compra de bienes duraderos. [fre] Allocation intertemporelle de la consommation, développements récents . par Jérôme Adda . Cet article présente les développements récents de la théorie de la répartition intertemporelle de la consommation et de l'épargne. Nous partons du modèle de revenu permanent à anticipations rationnelles. Ce modèle ne permet pas de rendre compte de la faible volatilité de la consommation par rapport au revenu ou la sensibilité excessive aux variations du revenu courant. Les développements récents ont alors introduit plusieurs extensions. L'étude de comportements prudents permet d'étudier l'épargne de précaution, ainsi que de mieux prendre en compte les effets du risque sur la consommation. Les contraintes de liquidité permettent d'expliquer le lien entre consommation et revenu courant. Enfin, l'étude de fonctions d'utilité non séparables dans le temps permet d'expliquer la persistence de la consommation et de modéliser des habitudes de consommation ou l'achat de biens durables. [eng] The Intertemporal Allocation of Consumption: Recent Developments, . by Jérôme Adda.. . This article presents recent developments in the theory of the intertemporal distribution of consumption and savings. We use as our starting point the model of permanent income with rational expectations. This model does not account for the low volatility of consumer spending compared with income or the excessive sensitivity of current income to fluctuations. Recent developments have therefore introduced a number of extensions. A study of careful behaviour is used to analyze prudential saving and better take into account the effects of risk on consumer spending. Cash flow constraints explain the link between consumption and current income. Lastly, a study of utility functions that are inseparable over time explains the persistence of consumption and is used to model consumption habits and purchases of durable goods. [ger] Intertemporale Konsumallokation: die jüngsten Entwicklungen, . von Jérôme Adda.. . In diesem Artikel werden die jüngsten Entwicklungen der Theorie über die intertemporale Verteilung des Konsums und der Spartätigkeit präsentiert. Ausgegangen wird vom Modell des ständigen Einkommens mit rationalen Erwartungen. Mit diesem Modell läßt sich die geringe Volatilität des Konsums im Verhältnis zum Einkommen oder die iibermäßige Sensitivität gegenüber den Schwankungen des laufenden Einkommens nicht erklären, weshalb im Zuge der jüngsten Entwicklungen mehrere Erweiterungen hinzugenommen worden sind. Die Untersuchung der umsichtigen Verhaltensweisen ermöglicht eine Analyse der Spartätigkeit zur Risikovorsorge sowie eine bessere Berücksichtigung der Auswirkungen des Risikos auf den Konsum. Die Beziehung zwischen Konsum und laufendem Einkommen läßt sich mit den Liquiditätszwängen erklären. Die Untersuchung von zeitlich nicht trennbaren Nutzenfunktionen gestattet es ferner, den Fortbestand des Konsums zu erklären und Konsumgewohnheiten oder den Kauf von Gebrauchsgütern zu modellieren.
