- Abstract
- We present a quarterly narrative database of important labour market reforms in selected euro area economies in between 1995 and 2018 covering 60 events. We provide legal adoption and implementation dates of major reforms to employment protection legislation and unemployment benefits. Estimates based on local projections find negative short-run effects of liberalising reforms on wages, while the employment effects of reforms differ markedly across age groups and partly depend on the state of the economy.

- Abstract
- Using new quarterly narrative evidence, this paper examines the macroeconomic impact of reforms of unemployment benefits (UB) and employment protection legislation (EPL) in the euro area from a Bayesian narrative panel VAR. The approach complements existing micro-econometric evidence by aligning short- and mediumterm effects in a unified framework and assessing state dependencies. Liberalising reforms result in temporary wage declines and highly persistent increases in economic activity and employment. In contrast to UB reforms, the effects of EPL reforms on employment emerge only gradually.

- Abstract
- Many countries have implemented macroprudential policies. The aims are twofold: first, to render the financial system more resilient to shocks and, second, to prevent booms and busts in the financial system in response to economic cycles. This article provides theoretical and empirical evidence which shows the positive impact that these measures have on financial stability, as well as the gains in economic growth derived from a stronger financial system.

- Abstract
- Since the global financial crises, many countries have implemented macroprudential policies with the aim to render the financial system more resilient to shocks and limit the procyclicality of the financial system. We present theoretical and empirical evidence on the effectiveness of macroprudential policy, on both, financial stability and economic growth focussing on capital measures and borrower-based measures.

- Abstract
- We study state dependence in the impact of monetary policy shocks over the leverage cycle for a panel of 10 euro area countries. We use a Bayesian Threshold Panel SVAR with regime classifications based on credit and house prices cycles. We find that monetary policy shocks trigger a smaller response of GDP, but a larger response of inflation during low states of the cycle. The shift in the inflation-output trade-off may result from higher macro-economic uncertainty in low leverage states. For an alternative regime classification based on turning points we find larger effects on GDP during contractions.

- Abstract
- We study the identification of policy shocks in Bayesian proxy VARs for the case that the instrument consists of sparse qualitative observations indicating the signs of certain shocks. We propose two identification schemes, i.e. linear discriminant analysis and a non-parametric sign concordance criterion. Monte Carlo simulations suggest that these provide more accurate confidence bounds than standard proxy VARs and are more efficient than local projections. Our application to U.S. macroprudential policies finds persistent effects of capital requirements and mortgage underwriting standards on credit volumes and house prices together with moderate effects on GDP and inflation.

- Abstract
- This paper studies the cyclical properties of real GDP, house prices, credit, and nominal liquid financial assets in 17 EU countries, by applying several methods to extract cycles. The estimates confirm earlier findings of large medium-term cycles in credit volumes and house prices. GDP appears to be subject to fluctuations at both business-cycle and medium-term frequencies, and GDP fluctuations at medium-term frequencies are strongly correlated with cycles in credit and house prices. Cycles in equity prices and long-term interest rates are considerably shorter than those in credit and house prices and have little in common with the latter. Credit and house price cycles are weakly synchronous across countries and their volatilities vary widely – these differences may be related to the structural properties of housing and mortgage markets. Finally, DSGE models can replicate the volatility of cycles in house and equity prices, but not the persistence of house price cycles.

- 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
- One foundation for developing new macroprudential policy in addition to traditional macroeconomic stabilisation policy is that financial cycles differ from business cycles. This article identifies properties of credit and housing cycles, shows how they relate to GDP cycles, and compares the reliability of real-time estimates.

- Abstract
- We use multivariate unobserved components models to estimate trend and cyclical components in GDP, credit volumes and house prices for the U.S. and the five largest European economies. With the exception of Germany, we find large and long cycles in credit and house prices, which are highly correlated with a medium-term component in GDP cycles. Differences across countries in the length and size of cycles appear to be related to the properties of national housing markets. The precision of pseudo real-time estimates of credit and house price cycles is roughly comparable to that of GDP cycles.

- Abstract
- Forecasts from dynamic factor models potentially benefit from refining the data set by eliminating uninformative series. The paper proposes to use prediction weights as provided by the factor model itself for this purpose. Monte Carlo simulations and an empirical application to short-term forecasts of euro area, German, and French GDP growth from unbalanced monthly data suggest that both prediction weights and Least Angle Regressions result in improved nowcasts. Overall, prediction weights provide yet more robust results.

- Abstract
- I estimate network dependence effects in the euro area unsecured overnight interbank market during the ?financial crisis. I use linear spatial regressions to estimate the dependence of individual banks?trading volumes (and interest rates) on the trading volumes (and interest rates) of their network neighbours. Neighbours are de?fined from past trading relations. I ?find that banks?net lending volumes and lending-borrowing interest rate spread depend negatively on their neighbours? respective outcomes. By contrast, there arise positive effects for total trading volume and borrowing rates. Overall, however, these effects are small and signi?ficant only in periods of market turmoil or of major policy interventions. The results suggest that neighbours act as a buffer in absorbing idiosyncratic liquidity shocks.

- Abstract
- We estimate and forecast growth in euro area monthly GDP and its components from a dynamic factor model due to Doz et al. (2005), which handles unbalanced data sets in an efficient way. We extend the model to integrate interpolation and forecasting together with cross-equation accounting identities. A pseudo real-time forecasting exercise indicates that the model outperforms various benchmarks, such as quarterly time series models and bridge equations in forecasting growth in quarterly GDP and its components.

- Abstract
- Global financial integration unlocks a huge potential for international risk sharing. We examine the degree to which international equity holdings act as a risk sharing device in industrial and emerging economies. We split equity returns into investment income (dividend distribution) and capital gains to investigate which of the two channels delivers the largest potential for risk sharing. Our evidence suggests that net capital gains are a more potent channel of risk sharing. They behave in a countercyclical way, that is they tend to be positive (negative) when the domestic economy is growing more slowly (rapidly) than the rest of the world. Countries with more countercyclical net capital gains experience improved consumption risk sharing. The empirical analysis furthermore suggests that these risk sharing properties of net capital gains have increased through time, in particular in the 1990s and early-2000s, on the back of a declining equity home bias and financial market deepening.

- Abstract
- This paper evaluates different models for the short-term forecasting of real GDP growth in ten selected European countries and the euro area as a whole. Purely quarterly models are compared with models designed to exploit early releases of monthly indicators for the nowcast and forecast of quarterly GDP growth. Amongst the latter, we consider small bridge equations and forecast equations in which the bridging between monthly and quarterly data is achieved through a regression on factors extracted from large monthly datasets. The forecasting exercise is performed in a simulated real-time context, which takes account of publication lags in the individual series. In general, we find that models that exploit monthly information outperform models that use purely quarterly data and, amongst the former, factor models perform best.

- Abstract
- We derive forecast weights and uncertainty measures for assessing the role of individual series in a dynamic factor model (DFM) to forecast euro area GDP from monthly indicators. The use of the Kalman filter allows us to deal with publication lags when calculating the above measures. We find that surveys and financial data contain important information beyond the monthly real activity measures for the GDP forecasts. However, this is discovered only, if their more timely publication is properly taken into account. Differences in publication lags play a very important role and should be considered in forecast evaluation.

- Abstract
- The first official data releases of quarterly real GDP for the euro area are published about eight weeks after the end of the reference quarters. Meanwhile, ongoing economic developments must be assessed from various, more readily available, monthly indicators. We examine in the context of univariate forecasting equations to what extent monthly indicators provide useful information for predicting euro area real GDP growth over the current and the next quarter. In particular, we investigate the performance of the equations under the case that the monthly indicators are only partially available within the quarter. For this purpose, we use time series models to forecast the missing observations of monthly indicators. We then examine GDP forecasts under different amounts of monthly information. We find that already a limited amount of monthly information improves the predictions for current-quarter GDP growth to a considerable extent, compared with ARIMA forecasts.

- Abstract
- The paper investigates real-time output gap estimates for the euro artea obtained from various unobserved components (UOC) models. Based on a state space modelling framework, three criteria are used to evaluate real-time estimates, I.e. standard errors, unbiasedness and conditional inflation forecasts. Real time estimates from univariate moving average filters and from bivariate UOC models based on output and inflation are found to be rather uninformative. Extended models, which employ the information from cyclical indicators and factor inputs, however, improve substantially upon the former models in all criteria. The pessimism on the reliability of real-time output gap estimates expressed in earlier literature may therefore be overstated.
