We assess empirically whether monetary policy announcements impact firm expectations. Two features of our data set are key. First, we rely on a survey of production and price expectations of German firms, that is, expectations of actual price setters. Second, we observe the day on which firms...

"Big G" typically refers to aggregate government spending on a homogeneous good. In this paper, we open up this construct by analyzing the entire universe of procurement contracts of the US government and establish five facts. First, government spending is granular, that is, it is concentrated...

Imports feature at all stages of production as well as in final consumption, and this is key to how tariff shocks play out. If imposed on imports in upstream sectors, import tariffs lower domestic output in downstream sectors; if imposed downstream, they raise upstream production. The aggregate...

How should monetary policy respond to excessive capital inflows that appreciate the currency and widen the external deficit? Using the workhorse two-country open-macro model, we derive a quadratic approximation of the utility-based global loss function in incomplete market economies, and solve...

As part of the green transition, the European cap-and-trade scheme for CO2 emissions will be extended to cover consumer durables. We propose a New Keynesian model that features both, "brown" and "green" durable goods and show that if monetary policy follows a business-as-usual approach, the...

The jointly optimal monetary and fiscal policy mix in a multi-sector New Keynesian model with sectoral government spending and productivity shocks entails a separation of roles: Sectoral government spending optimally adjusts to sectoral output gaps and inflation rates---a policy supported by...

In the aftermath of the global financial crisis, the state of macroeconomicmodeling and the use of macroeconomic models in policy analysis has come under heavy criticism. Macroeconomists in academia and policy institutions have been blamed for relying too much on a particular class of...
