This paper analyzes the reaction of exporters to exchange rate changes. We present a model where, in the presence of distribution costs in the export market, high and low productivity firms react differently to a depreciation . Whereas high productivity firms optimally raise their markup rather...

We analyze the interaction of economic and political determinants of free trade agreements (FTA). In addition to standard trade gains, FTAs can promote peaceful relations by offering a political forum and by increasing the opportunity cost of conflicts that disrupt trade. If policy makers...

In the early stage of the 2008-2009 financial crisis, the conventional wisdom was that financial under-development of sub Saharan African economies may be a blessing in disguise because it insulates them from the direct effects of the crisis. This paper argues that this may also make African...

This paper analyses the welfare implications of international spillovers related to productivity gains, changes in market size, or government spending. We introduce trade costs and endogenous varieties in a two-country general-equilibrium model with monopolistic competition, drawing a...

Most analyses of the macroeconomic adjustment required to correct global imbalances ignore net exports of new varieties of goods and services and do not account for firms' net entry in the product market. In this paper we revisit the macroeconomics of trade adjustment in the context of the...

The paper analyses, along the transition path and in steady state, the optimal stabilization policy in an economy in which growth is driven by learning by doing. If future benefits of learning by doing are not fully internalized by workers the optimal fiscal policy is to tax labour during...

We review the theoretical links between growth and agglomeration. Growth, in the form of innovation, can be at the origin of catastrophic spatial agglomeration in a cumulative process à la Myrdal. One of the surprising features of the Krugman (1991) model, was that the introduction of partial...

We analyse the effect of trade spillovers and of international coordination on currency crises. To do this, we present a model that builds on two separate literatures: the literature on international monetary cooperation on the one hand, and the literature on currency crises, or more precisely...

This paper analyzes empirically the relationship between civil wars and international trade. We first show that trade destruction due to civil wars is very large and persistent and increases with the severity of the conflict. We then test the presence of two effects that trade can have on the...

This paper constructs a two-region endogenous growth model, where economic geography and public infrastructures play a key role. The model allows us to analyse the contribution of different types of redistributive public policies on growth, industrial geography and spatial income distribution....
