Real exchange rates are highly volatile and persistent. I provide a novel structural explanation for these facts using a model with dispersed information among firms. When producers face strategic complementarities in price-setting, uncertainty about competitors' beliefs results in sluggish...

This paper studies the role of the exchange rate regime for trade of new products. It first provides VAR evidence that a rise in external productivity shifts trade away from new products and more so in fixed regimes. Then, it presents a model with firm dynamics in line with this evidence. We...

According to the two-country full information New Keynesian model with flexible exchange rates, the real exchange rate appreciates in response to an asymmetric negative demand shock at the zero lower bound (ZLB) and exacerbates the adverse macroeconomic effects. This finding requires inflation...

We set up and estimate a structural unobserved components open economy model for the rate of unemployment and the real exchange rate in Sweden. This approach enables us to simultaneously determine changes in both cyclical and equilibrium rates. Our results show that the Natural Rate/NAIRU has...

The empirical effectiveness of economic policies that operate theoretically through similar channels differs substantially. We document this fact by comparing an easy-to-grasp expectations-based policy, unconventional fiscal policy, with a policy whose implications are harder to understand by...

Binding lower bounds on interest rates and large government deficits limit the scope of fiscal and monetary policies to stimulate households' spending through financial intermediaries and firms. Policymakers have thus been implementing unconventional policies that aim to increase households'...

DSGE models based on New Keynesian principles, which have been extended to allow for banking, the zero lower bound on interest rates (ZLB), and varying price duration, can account well for recent macroeconomic behavior across a variety of economies. These models Önd that active Öscal policy...

We examine the dynamic properties of inflation in a model of optimal discretionary fiscal and monetary policies. The lack of commitment and the presence of nominally risk-free debt provide the government with an incentive to implement policies which induce positive and persistent inflation...

We study the monetary instrument problem in a model of optimal discretionary fiscal and monetary policy. The policy problem is cast as a dynamic game between the central bank, the fiscal authority, and the private sector. We show that, as long as there is a conflict of interest between the two...

The purpose of this paper is to present an approach with regard to the dynamic process of the general equilibrium during the business cycle fluctuations following monetary and fiscal interventions, which, I think, could contribute to bridging the differences between the different schools of...
