This paper introduces trade costs and endogenous number of varieties in an open economy model with monopolistic competition and short run nominal wage rigidities. We show that these two elements have important implications for the international transmission of monetary and productivity shocks....

'New open economy macroeconomics' (NOEM) refers to a body of literature embracing a new theoretical framework for policy analysis in open economy, aiming to overcome the limitations of the Mundell-Fleming model while preserving the empirical wisdom and policy friendliness of traditional...

We study a model in which policy aims at aggregate price stability. A fiscal imbalance materializes that, if uncorrected, must cause inflation, but the imbalance may get corrected in the future with some probability. By maintaining price stability in the near term, monetary policy can buy time...

The impact of fiscal stimulus depends not only on short-term tax and spending policies, but also on expectations about offsetting measures in the future. This paper analyzes the effects of an increase in government spending under a plausible debt-stabilizing policy that systematically reduces...

The notion that flexible exchange rates insulate a country from foreign shocks is well grounded in theory, from the classics (Meade, 1951; Friedman 1953), to the more recent open economy literature (Obstfeld and Rogo, 2000). We confront it with new evidence from Europe. Specifically, we study how...

We confront the notion that flexible rates insulate a country from external disturbances with new evidence on spillovers from euro-area shocks to neighboring countries. We find that in response to euro-area shocks, spillovers are not smaller, and currency movements not significantly larger, in...

A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account...

This paper analyzes 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...
