We analyze fiscal consolidations using a New-Keynesian model where agents have finite planning horizons and are uncertain about the future state of the economy. Both consumers and firms are infinitely lived, but only plan and form expectations up to a finite number of periods into the future. The length of agents' planning horizons plays an important role in determining how spending cuts or tax increases affect output and inflation. We find that for low degrees of relative risk aversion spending-based consolidations are less costly in terms of output losses, in line with empirical evidence. A stronger response of monetary policy to inflation makes spending-based consolidations more favorable as well. Interestingly, for short planning horizons, our model captures the positive comovement between private consumption and government spending observed in the data.

We study the global macroeconomic effects of tariffs using a multiregional, general equilibrium model, EAGLE, that we extend by introducing US tariffs against Chinese imports into the US, and subsequently Chinese tariffs against US imports into China, consistent with recent trade policies by the US and the Chinese governments. We abstract from tariffs on goods exported from the euro area, focusing on a US-China trade war. A unilateral tariff from the US against China dampens US exports in line with the Lerner Symmetry theorem but global output contracts. Global output contracts even further after China retaliates. The euro area benefits from this trade war. These European trade diversion benefits are caused by cheaper imports from China and improved competitiveness in the US. As price stickiness in the export sector in each region increases, the negative effects of tariffs in the US and China are mitigated, but the positive effects in the euro area are then also dampened.

This paper explores the optimal allocation of government bond purchases within a monetary union, using a two-region DSGE model, where regions are asymmetric with respect to economic size and portfolio characteristics: the extent of substitutability between assets of different maturity and origin, asset home bias, and steady-state levels of government debt. An optimal quantitative easing (QE) policy under commitment does not only reflect different region sizes but is also a function of these dimensions of portfolio heterogeneity. By calibrating the model to the euro area, we show that optimal QE favors purchases from the smaller region (Periphery instead of Core), given that the former faces stronger portfolio frictions. A fully optimal policy consisting of both the short-term interest rate and QE lifts the monetary union away from the zero lower bound faster than an optimal interest rate policy alone, which entails forward guidance.

This paper analyses the effects of the COVID-19 pandemic shock on small open economies in a monetary union with an application to the euro area. Accounting for a high degree of openness and a strong dependence on intra and extra union trade, we focus on the size and the direction of international spillovers both from the shock itself and from the ensuing fiscal response. To do so, we use a unifted modelling framework: The Euro Area and the Global Economy (EAGLE) model. Furthermore, within this general framework, we assess the extent to which speciftc modelling features shape the dynamic responses to the COVID-19 pandemic. The main messages are as follows. First, fiscal spillovers from the rest of the monetary union do matter. Second, the effective lower bound ampliftes the size of the spillovers. Third, the design of wage negotiations leads to wage subsidies having negative international fiscal policy spillovers. Fourth, import content of government spending interacts with the effective lower bound, strongly affecting the size and sign of spillovers. Fifth, when households have finite lifetimes, the responses of output and inflation are amplifted compared to the case with infinitely lived households. Finally, a next generation EU instrument is more effective when financed using a tax on consumption.
