Copublished with the Brookings Institution, Washington D.C. and the Centre for Economic Policy Research, London, and edited by Ralph Bryant, David Currie, Jacob A. Frenkel, Paul Masson, and Richard Portes, this volume considers economic interdependence among well developed countries as well as...

This paper compares two contrasting approaches to robust monetary policy design. The first developed by Hansen and Sargent (2003, 2007) assumes unstructured model uncertainty and uses a minimax robustness criterion to design monetary rules. This contrasts with an older literature that structures...

We extend the Benassy (1996) 'taste for variety' model to an open economy setting. With the Benassy effect, the market equilibrium is inefficient, openness reduces the varieties provided in the unconstrained optimum and there are potential gains from international coordination. -- Taste for...

The objectives of this paper are : first, to quantify the stabilization welfare gains from commitment; second, to examine how commitment to an optimal rule can be sustained as an equilibrium and third, to find a simple interest rate rule that closely approximates the optimal commitment one. We...

We examine the linear-quadratic (LQ) approximation of non-linear stochastic dynamic optimization problems in macroeconomics, in particular for monetary policy. We make four main contributions: first, we draw attention to a general Hamiltonian framework for LQ approximation due toMagill (1977)....
