- Abstract
- Understanding asymmetric risks in macroeconomic variables is challenging. Most structural models used for policy analysis are linearised and therefore cannot generate asymmetries such as those documented in the empirical growth-at-risk (GaR) literature. This report examines how structural models can incorporate non-linearities to generate tail risks. The first part reviews the various extensions to dynamic stochastic general equilibrium (DSGE) models and the computational challenges involved in accounting for risk distributions. This includes the use of occasionally binding constraints and more recent developments, such as deep learning, to solve non-linear versions of DSGEs. The second part shows how the New Keynesian DSGE model, augmented with the vulnerability channel as proposed by Adrian et al. (2020a, b), satisfactorily replicates key empirical facts from the GaR literature for the euro area. Furthermore, introducing a vulnerability channel into an open-economy set-up and a medium-sized DSGE highlights the importance of foreign financial shocks and financial frictions, respectively. Other non-linearities arising from financial frictions are also addressed, such as borrowing constraints that are conditional on an asset’s value, and the way macroprudential policies acting against those constraints can help stabilise the economy and generate positive spillovers to monetary policy. Finally, the report examines how other types of tail risk beyond financial frictions – such as the recent asymmetric supply-side shocks – can be incorporated into macroeconomic models used for policy analysis.

- Abstract
- In the low inflation and low interest rate environment that prevailed over the period 2013-2020, many argued that besides expansionary monetary policy, expansionary fiscal policy could also support central banks’ efforts to bring inflation closer to target. During the pandemic, proper alignment of fiscal and monetary policy was again crucial in promoting a rapid macroeconomic recovery. Since the end of 2021 an environment of higher inflation, lower growth, higher uncertainty, and higher interest rates has changed the nature of the required policy mix and poses different challenges to the interaction between monetary and fiscal policy. Following up on the work done under the ECB’s 2020 strategy review (see Debrun et al., 2021), this report explores some of the renewed challenges to monetary and fiscal policy interactions in an environment of high inflation. The main general conclusion is that, with an independent monetary policy that aims to bring inflation back to target in a timely manner, it is still possible to design fiscal policy in a way that protects vulnerable parts of society against the costs of high inflation without pulling against the central bank’s effort to tame inflation. This is more likely to be the case if fiscal measures are temporary and targeted, and if priority is given to structural reforms and public investment in support of potential growth. The latter is particularly effective in reshaping the supply side of the economy in a manner that is likely to have a lasting positive structural impact.

- Abstract
- 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 unified modelling framework: The Euro Area and the Global Economy (EAGLE) model. Furthermore, within this general framework, we assess the extent to which specific 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 amplifies 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 amplified compared to the case with infinitely lived households. Finally, a next generation EU instrument is more effective when financed using a tax on consumption.
