This paper illustrates using a very simple model that admits a close form solution that takes risk into account how to apply the existing numerical methods in a very simple way. Contrary to most existing models to teach solution methods, this model possesses non trivial properties as far as risk...

Recent studies of aggregate job flows in the US economy indicate that (i) specific sectoral shocks are important to account for aggregate job flows dynamics and (ii) aggregate creation and destruction dynamics display significant non-linearities. This paper aims to study whether a simple...

This paper contributes to the analysis of jobs flows dynamics through the explicit modelling of job creations and job destructions. We propose a simple matching model extended for endogenous separation and tractable heterogeneity. The parameters of the model are estimated using a...

This paper presents the original and main contributions of T. Sargent and C. Sims to macro-economic modeling. We first briefly review the critics Sargent and Sims addressed to existing modeling. We then emphasize the originality of their two respective approaches. We finally show how their...
