This paper shows that optimal unemployment insurance contracts are age-dependent. Older workers have only a few years left on the labor market prior to retirement. This short horizon implies a more decreasing replacement ratio. However, there is a sufficiently short distance to retirement for...

Finding solutions to the Bellman equation relies on restrictive boundedness assumptions. The literature on endogenous growth or business cycle models with unbounded random shocks provide with numerous examples of recursive programs in which returns are not bounded along feasible paths. In this...

This paper analyses optimal paths in a one-sector growth model when the technology is not convex. In such a case, we prove that optimal paths converge to the upper steady state iff the initial wealth is above a critical level. Then we first show that thanks to debt and/or R&D the poverty trap...

We prove the existence of unique solutions for all undetermined coefficients of nonlinear perturbations of arbitrary order in a wide class of discrete time DSGE models under standard regularity and saddle stability assumptions for linear approximations. Our result follows from the...

Ce papier se propose d’analyse la dynamique de la politique monétaire en République démocratique du Congo (RDC), en adoptant une approche de modélisation par l’équilibre général dynamique stochastique (DSGE). Le modèle DSGE construit à cet effet considère trois relations...

This paper depicts the negative impact of a falling real wage caused by reduced bargaining power of workers on aggregate demand and employment. Contrary to standard New Keynesian models, the presence of consumers not participating in financial markets (rule of thumb consumers) causes an...

The standard two-sector monetary business cycle model suffers from an important deficiency. Since durable good prices are more flexible than non-durable good prices, optimising households build up the stock of durable goods at low cost after a monetary contraction. Consequently, sectoral outputs...

This paper presents some results of the computable, general-equilibrium, multiregional overlapping-generations model INGENUE. The purpose of this research is to analyse the issues relating to wealth accumulation and alternative pension reforms in the context of global finance. Hence it focuses...

Le PERP, mis en place en 2003, occupe une place centrale dans le dispositif d'épargne retraite par capitalisation en France. Nous étudions son caractère redistributif en calculant les taux de rendement interne pour des situations types qui varient en fonctions de la catégorie sociale, du...

We estimate small open economy models with involuntary unemployment using Australian data from 1993 to 2007, focusing on hiring costs and real wage rigidity. We find a strong preference for models with hiring costs, which account for 0.97% of GDP. The data favour models with real over nominal...
