There is a huge literature on the effects of uncertainty on trade levels. One very strong result of that literature is that uncertainty should not matter, as long as well developed forward markets exist. The empirical implications of this result, however, are hard to find in the data. We model...

We develop a simple open-economy AK model with collateral constraints that accounts for growth-reversal episodes, during which countries face abrupt changes in their growth rate that lead to either growth miracles or growth disasters. Absent commitment to investment by the borrowing country,...

This paper investigates the relative price and relative wage effects of a higher productivity in the traded sector compared with the non traded sector in a two-sector open economy model with imperfect substitutability in hours worked across sectors. The Balassa-Samuelson [1964] model predicts...

This paper casts the Belgian Great Depression of the 1930s within a dynamic stochastic general equilibrium (DSGE) framework. Results show that a total factor productivity shock within a standard real business cycle model is unsatisfactory. Introducing war expectations in the baseline model...

On utilise le modèle d'accumulation optimale de Rarnsey pour analyser la dynamique des inégalités au sein d'un pays s'ouvrant aux échanges avec un pays plus pauvre. Avec une fonction de production Cobb-Douglas, le modèle prédit, en même temps qu'une augmentation des inégalités de...

Dans un modèle à deux pays et à horizon infini, dans lequel la mobilité du capital est imparfaite, on présente une analyse dynamique de la transmission internationale des chocs qui affectent les dépenses publiques. Trois types de financements d'une augmentation des dépenses publiques sont...

We provide a North-South Schumpeterian growth model endogenously generating demand-driven patterns of vertical intra-industrial trade. More precisely, we build a model featuring non-homothetic preferences and income differences, and show that such conditions guarantee the endogenous emergence of...

We develop a new methodology to identify high-end variety exporters in French firm-level data. We show that they do not export to many more countries, but they export to more distant ones. This comes with a greater geographic diversification of their aggregate exports. These facts are explained...
