The euro area's pandemic recession: A DSGE-based interpretation.

This paper augments the European Commission's open-economy DSGE model (GM) with COVID-specific shocks ('forced savings', labour hoarding) and financially-constrained investors to account for the extreme volatility of private domestic demand and hours worked during COVID-19, and it estimates the model on euro area data for the period 1998q4-2021q4. It takes a pragmatic approach of adapting the workhorse model of a policy institution to COVID-19 data. 'Forced savings' are central to explain quarterly real GDP growth during the pandemic, complemented by contributions from foreign demand and trade, and the negative impact of persistently higher savings after the first wave. We provide extensive model validation, including a comparison to off-model evidence for COVID-related restrictions, and a comparison of different model specifications.

Financial spillover and global risk in a multi-region model of the world economy.

This paper estimates a three-region DSGE model (EA, US, RoW) with international financial linkages in the form of cross-border equity holding and allowing for region-specific as well as global financial shocks, which match empirical measures of financial tightness and global stock market valuation. Spillover from financial shocks increases with international financial integration and is practically zero under full home bias in normal times. The global risk captures international synchronisation of financial cycles. Spillover of financial shocks is amplified at the zero lower bound, at which investment risk takes on the characteristics of a general uncertainty shock. The model results suggest that integrated financial markets should provide a powerful motivation for international policy coordination to prevent financial turmoil.
