We study a benchmark model with collateral constraints and heterogeneous discounting. Contrarily to a rich literature on borrowing limits, we allow for rental markets. By incorporating this missing market, we show that impatient agents choose to rent rather than to own the collateral in the...

How should monetary policy be optimally designed in an environment with high degrees of financial globalization ? To answer this question we lay down an open economy model where net lending toward the rest of the world is constrained by a collateral constraint motivated by limited enforcement....

In this article, we focus on current account dynamics in large open economies characterized by debt-constrained heterogeneous agents and endogenous monetary policies. We incorporate three key features that have bulked large in the New Open Macroeconomics literature : i) home bias in trade, ii)...

Dans cet article, nous présentons la modélisation du secteur financier dans la littérature des MEGIS. Ces maquettes de l'économie visent à quantifier l'impact sur les variables d'intérêt (inflation, prix des actifs, PIB, taux d'intérêt par exemple) de l'ensemble des interactions des...

We provide a quantitative assessment of welfare costs of fluctuations in a search model with financial frictions. The matching process in the labor market leads positive shocks to reduce unemployment less than negative shocks increase it. We show that the magnitude of this non-linearity is...

Dans cet article, nous proposons une revue de la littérature sur les frictions financières dans les modèles d'équilibre général intertemporels et stochastiques. Nous présentons en premier lieu les contributions pionnières qui ont analysé les effets d'amplification associés à...

In this paper, we expose the results of a voting experiment realised in 2007, during the French Presidential election. This experiment aimed at confronting the Single Transferable vote (SVT) procedure to two criteria : simplicity and the selection of a Condorcet-winner. Building on our electoral...
