In locally linearized dynamic stochastic rational‐expectations models, I introduce the concepts of feasible paths (paths on which the policy instrument can be expressed as a function of the policymaker's observation set) and implementable paths (paths that can be...

We consider a broad class of linear dynamic stochastic rational-expectations models made of a finite number N of structural equations for N+1 endogenous variables and to be closed by one policy feedback rule. We design, for any model of this class and any stationary VARMA solution of that model,...

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...

Against all odds, the euro turned out to be a weak currency. We argue that this outcome can readily be explained by the policy mix that was chosen at the onset of the period: tight fiscal policies following the convergence mechanism that was imposed by the Maastricht treaty and loose monetary...
