The distributional and disruptive effects of energy supply shocks are potentially large. We study the effectiveness of alternative fiscal responses in a two-country HANK model calibrated to the euro area. Subsidies can stabilize the domestic economy, but they are fiscally costly and generate...

Under inflation forecast targeting, central banks such as the ECB adjust policy to keep expected inflation on target. We evaluate the ECB’s inflation forecasts: they are unbiased and efficient but contain little information at forecast horizons beyond three quarters. In a New Keynesian model...

Attitudes toward fiscal policy differ: fiscal conservatism and fiscal liberalism vary in their willingness to tolerate budget deficits. We challenge the view that such attitudes reflect national preferences. Instead, we offer an economic explanation based on a two-country Heterogeneous Agent New...

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...

What determines the effectiveness of military buildups? We introduce the concept of the military multiplier: the percentage increase in military equipment an additional dollar buys. It varies with the costs of allocating resources to military production, depending, among other things, on the...

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...

When confronted with sectoral shocks, policymakers often resort to targeted, sector-specific taxes in an \emph{ad hoc} fashion. Based on the New Keynesian Network model, we characterize the optimal tax response to sectoral shocks: it features twice as many tax instruments as there are sectors,...

The business cycle is driven by expectations - some justified, some not - as documented by a host of studies. What is less clear are the conditions that make the economy susceptible to "sentiment shocks." In this paper, we document that uncertainty, as measured by forecaster disagreement, is...
