- 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
- This paper analyses the implications of climate change for the conduct of monetary policy in the euro area. It first investigates macroeconomic and financial risks stemming from climate change and from policies aimed at climate mitigation and adaptation, as well as the regulatory and fiscal effects of reducing carbon emissions. In this context, it assesses the need to adapt macroeconomic models and the Eurosystem/ECB staff economic projections underlying the monetary policy decisions. It further considers the implications of climate change for the conduct of monetary policy, in particular the implications for the transmission of monetary policy, the natural rate of interest and the correct identification of shocks. Model simulations using the ECB’s New Area-Wide Model (NAWM) illustrate how the interactions of climate change, financial and fiscal fragilities could significantly restrict the ability of monetary policy to respond to standard business cycle fluctuations. The paper concludes with an analysis of a set of potential monetary policy measures to address climate risks, insofar as they are in line with the ECB’s mandate.

- Abstract
- This paper provides an assessment of the macroeconomic models regularly used for forecasting and policy analysis in the Eurosystem. These include semi-structural, structural and time-series models covering specific jurisdictions and the euro area within a closed economy, small open economy, multi-country or global setting. Models are used as analytical frameworks for building baseline projections and for supporting the preparation of monetary policy decisions. The paper delivers four main contributions. First, it provides a survey of the macroeconomic modelling portfolios currently used or under development within the Eurosystem. Second, it explores the analytical gaps in the Eurosystem models and investigates the scope for further enhancement of the main projection and policy models, and the creation of new models. Third, it reviews current practices in model-based analysis for monetary policy preparation and forecasting and provides recommendations and suggestions for improvement. Finally, it reviews existing cooperation modalities on model development and proposes alternative sourcing and organisational strategies to remedy any knowledge or analytical gaps identified.

- Abstract
- We quantify the size of fiscal multipliers under financial fragmentation risk and demonstrate how non-standard monetary policy can support the macroeconomic transmission of fiscal interventions. We employ a DSGE model with financial frictions whereby the interplay of corporate, banks and sovereign solvency risk affect the transmission of fiscal policy. The output multiplier of fiscal expansion is found to be significantly dampened by tighter financial conditions in case households are less certain about implicit and explicit state-guarantees for the banking system, or banks are weakly capitalized and highly exposed to the government sector. In this context, we show that central bank asset purchases or liquidity operations designed to ensure favourable bank funding conditions can restore fiscal multipliers.

- Abstract
- Through the euro area crisis, financial fragmentation across jurisdictions became a prime concern for the single monetary policy. The ECB broadened the scope of its instruments and enacted a series of non-standard measures to engineer an appropriate degree of policy accommodation. The transmission of these measures through the currency union remained highly dependent on the financial structure and conditions prevailing in various regions. This paper explores the country-specific macroeconomic transmission of selected non-standard measures from the ECB using a global DSGE model with a rich financial sector: we extend the six-region multi-country model of Darracq Pariès et al. (2016), introducing credit and exchange rate channels for central bank asset purchases. The portfolio rebalancing frictions are calibrated to match the sovereign yield and exchange rate responses after ECB's Asset Purchase Programme (APP) first announcement. The domestic transmission of the APP through the credit intermediation chain is significant and quite heterogenous across the largest euro area countries. The introduction of global portfolio frictions on euro area government bond holdings by international investors opens up for a larger depreciation of the euro. The interaction between international and domestic channels affect the magnitude and the cross-country distribution of the APP impact.

- Abstract
- This paper contributes to the debate on the macroeconomic effectiveness of expansionary non-standard monetary policy measures in a regulated banking environment. Based on an estimated DSGE model, we explore the interactions between central bank asset purchases and bank capital-based financial policies (regulatory, supervisory or macroprudential) through its influence on bank risk-shifting motives. We find that weakly-capitalised banks display excessive risk-taking which reinforces the credit easing channel of central bank asset purchases, at the cost of higher bank default probability and risks to financial stability. In such a case, adequate bank capital demand through higher minimum capital requirements curtails the excessive credit origination and restores a more efficient propagation of central bank asset purchases. As supervisors can formulate further capital demands, uncertainty about the supervisory oversight provokes precautionary motives for banks. They build-up extra capital buffer attenuating non-standard monetary policy. Finally, in a weakly-capitalised banking system, countercyclical macroprudential policy attenuates banks risk-taking and dampens the excessive persistence of the non-standard monetary policy impulse. On the contrary, in a well-capitalised banking system, macroprudential policy should look through the effects of central bank asset purchases on bank capital position, as the costs in terms of macroeconomic stabilisation seem to outweigh the marginal financial stability benefits.

- Abstract
- This paper investigates the interrelations between monetary macro- and microprudential policies. It first provides an overview of the three policies, starting with their main instruments and objectives. Monetary policy aims at maintaining price stability and promoting balanced economic growth, macroprudential policies aim at safeguarding the stability of the overall financial system, while microprudential policies contribute to the safety and soundness of individual entities. Subsequently, the paper provides a simplified description of their respective transmission mechanisms and analyses the interactions between them. A conceptual framework is first presented on the basis of which the analysis of the interactions across the different policies can be demonstrated in a stylised manner. These stylised descriptions are then further complemented by model-based simulations illustrating the significant complementarities and interactions between them. Finally, the paper concludes that from a conceptual point of view there are numerous areas of interaction between the policies. These create scope for synergies, which can be reaped by sharing information and expertise across the various policy areas.

- Abstract
- The euro area experience during the financial crisis highlighted the importance of financial and sovereign risk factors in macroeconomic propagation, as well as the constraints that bank lending fragmentation would pose for monetary policy conduct in a currency union. We design a 6-region multi-country DSGE model which provides a structural interpretation of the salient features of these developments. The model spans the relevant "financial wedges" at play during the crisis, together with its cross-country heterogeneity within the euro area, focusing on Ger- many, France, Italy, Spain, and rest-of-euro area. We construct three stylised macro-financial scenarios as a synopsis of the euro area financial crisis and argue that the adverse interactions between sovereign, banking and corporate risk, can account to a large extent for the financial repression and poor economic performance observed in some parts of the euro area.

- Abstract
- This paper analyses the challenges that high public debt and ageing populations pose to medium-term growth. First, macroeconometric model simulations suggest that medium-term growth can benefit from credible fiscal consolidation, partly through reductions in sovereign risk premia. Second, a disaggregated growth accounting exercise suggests that the impact of population ageing on medium-term growth can be mitigated by structural reforms boosting labour force participation. Finally, general equilibrium models suggest that pay-as-you-go public pension systems will require reforms combining lower benefits, a later retirement age and higher social contributions. These findings suggest several policy recommendations: (a)

- Abstract
- The onset of the financial crisis in 2008 has highlighted the problems of diverging external imbalances within Economic and Monetary Union (EMU) and the role of persistent losses in competitiveness. This paper starts by investigating some of the competitiveness factors which contributed to external imbalances in euro area countries. The evidence suggests significant heterogeneity across countries in both price/cost and non-price competitiveness in the euro area and that there is no one factor, but rather a range of potential factors explaining diverging external imbalances. In particular, while non-price competitiveness effects contributed largely to the trade surplus in some countries, for some southern European countries the trade balance was also driven by price factors. The second part of the paper studies the implications of competitiveness adjustment by means of quantitative tools. Using four different multi-country macro models, improvements in both price/cost aspects (namely wage reduction, productivity improvements or fiscal devaluation) and non-price competitiveness factors (quality improvements) were shown - under certain conditions - to improve external imbalances. The analysis suggests differences in countries' composition of trade could lead to heterogeneity in the potential gains from improvements in competitiveness.
