On the credit and exchange rate channels of central bank asset purchases in a monetary union

Throughout 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.     

Effects of asset purchases and financial stability measures on term premia in the euro area

We study the effects of the announcements of ECB asset purchases and of financial stability measures in the euro area in the wake of the global financial crisis and the euro area sovereign debt crisis on 10-year government bond term premia in 11 euro area countries. We find that the term premia of euro area countries with higher sovereign risk, as measured by sovereign CDS spreads, decreased more in response to the announcements of asset purchases and financial stability measures. Term premia of countries with lowest sovereign risk either increased as in Germany, or were not significantly affected or fell slightly, as in the Netherlands and Finland.     

A risk-driven approach to exchange rate modelling

The paper presents a new approach to exchange rate modelling that augments the CHEER model with a sovereign credit default risk as perceived by financial investors making their decisions. In the cointegrated VAR system with nine variables comprised of the short- and long-term interest rates in Poland and the euro area, inflation rates, CDS indices and the zloty/euro exchange rate, four long-run relationships were found. Two of them link term spreads with inflation rates, the third one describes the exchange rate and the fourth one explains the inflation rate in Poland. Transmission of shocks was analysed by common stochastic trends. The estimation results were used to calculate the zloty/euro equilibrium exchange rate.     

Euro area sovereign yield spreads as determinants of private sector borrowing costs

We regress long-term private-sector borrowing rates on a money market rate, a term premium and credit risk. As a contribution to the current debate about European safe assets, our interest is in quantifying the impact of euro area sovereign bond spreads on private-sector lending by employing it as a proxy for private-sector credit risk. Panel estimates show significant, albeit rather small long-run effects. Another finding is large cross-country heterogeneity. Using linear country-specific estimates, we find the effect to be significant in only some countries, but the size of the maximum effect in these countries exceeds the average one more than three-fold. Furthermore, for one country, we find an asymmetrical effect with positive spread changes having greater impact on private-sector borrowing costs than negative ones. Substantial heterogeneity of the spillover effect between euro area countries indicates the presence of financial valuation effects based not only on economic fundamentals. This, in turn, implies that spillovers may entail contagion costs. Overall, our results suggest that these costs are considerable in the euro area and will remain so until an effective form of European safe assets is created.     

The reliability of real-time estimates of the euro area output gap

This paper provides evidence on the reliability of euro area real-time output gap estimates. A genuine real-time data set for the euro area is used, including vintages of several sets of euro area output gap estimates available from 1999 to 2010. It turns out that real-time estimates of the output gap tend to be characterised by a high degree of uncertainty, much higher than that resulting from model and estimation uncertainty only. In particular, the evidence indicates that both the magnitude and the sign of the real-time estimates of the euro area output gap are very uncertain. The uncertainty is mostly due to parameter instability and model uncertainty, while data revisions seem to play a minor role. Some euro area real-time measures, based on multivariate components models and capacity utilisation, are relatively less uncertain, but do not appear to be fully reliable along some dimensions. To benchmark our results, we repeat the analysis for the US over the same sample. It turns out that US real-time estimates tend to be revised to a lesser extent than euro area estimates. However, euro area real-time output gap estimates tend to display a higher correlation with the final estimates and the sign of the level of US real-time estimates tends to be revised more often compared to the corresponding euro area estimates. In addition, the data revision component of the revision error is larger for US estimates than for the euro area. Overall, the unreliability in real-time of the US output gap measures detected in earlier studies is confirmed in the more recent period.     

The effect of the euro on foreign direct investment

In this paper the recent effect of the European Monetary Union on inward FDI-flows is examined using a difference-in-differences approach. The estimated results show that the introduction of the euro raised inward FDI flows by approximately 16% within the euro area, by approximately 11% to non-members and weakly by around 8% from non-member countries into the euro area. Moreover, the geographical effects of the euro are explored. The results show partial agglomeration tendencies for the euro area. There are also some indications of increased importance of vertical specialization in the sample.     

On the time-varying relationship between EMU sovereign spreads and their determinants

We use a dynamic multipath general-to-specific algorithm to capture structural instability in the link between euro area sovereign bond yield spreads against Germany and their underlying determinants over the period January 1999–August 2011. We offer new evidence suggesting a significant heterogeneity across countries, both in terms of the risk factors determining spreads over time as well as in terms of the magnitude of their impact on spreads. Our findings suggest that the relationship between euro area sovereign risk and the underlying fundamentals is strongly time-varying, turning from inactive to active since the onset of the global financial crisis and further intensifying during the sovereign debt crisis. As a general rule, the set of financial and macro spreads' determinants in the euro area is rather unstable but generally becomes richer and stronger in significance as the crisis evolves.     

The national segmentation of euro area bank balance sheets during the financial crisis

This paper analyses bank balance sheet data in conjunction with macroeconomic and other financial variables. Our aim is to understand the nature of the instability in financial intermediation in the euro area during the recent financial crises. We define “large changes” as significant departures in the actual evolution of balance sheet variables during the crisis from their historical association with the business and financial cycles. In the course of the global 2008–2009 financial crisis, such “large changes” were features of the behaviour of cross-border inter-bank flows, both within the euro area and between the euro area and the rest of the world. By contrast, retail assets and liabilities, as well as inter-bank flows among banks of the same country, did not significantly deviate from historical regularities. Since the euro area sovereign crisis of 2011–2012, “large changes” have been more pervasive. In particular, a significant home bias in the sovereign bond market has emerged.     

Are remittances an instrument of stabilization and funding in the euro area?

In this study, we explore the specific question of the counter cyclicality of remittances in the euro area, namely, if they could be used to stabilize the business cycle and as an additional source of external financing. This research uses data for 13 euro area countries in the period 2004–2013. For whole of the sample, our two hypotheses concerning stabilization and external financing are rejected, but Lithuania and Greece are outliers. Remittances seem to have had a macroeconomic stabilizing effect on Lithuania and to have mitigated in part the liquidity problems that Greece has faced since the sovereign debt crisis.     

The effect of ECB monetary policies on interest rates and volumes

This article assesses the transmission of ECB monetary policies, conventional and unconventional, to both interest rates and lending volumes or bond issuance for three types of different economic agents through five different markets: sovereign bonds at 6-month, 5-year and 10-year horizons, loans to nonfinancial corporations and housing loans to households, during the financial crisis, and for the four largest economies of the euro area. We look at three different unconventional tools: excess liquidity, longer-term refinancing operations and securities held for monetary policy purposes following the decomposition of the ECB’s Weekly Financial Statements. We first identify series of ECB policy shocks at the euro area aggregate level by removing the systematic component of each series and controlling for announcement effects. We second include these exogenous shocks in country-specific structural VAR, in which we control for credit demand. The main result is that only the pass-through from the ECB rate to interest rates has been effective. Unconventional policies have had uneven effects and primarily on interest rates.     

Data uncertainty and the role of money as an information variable for monetary policy

In this study, we perform a quantitative assessment of the role of money as an indicator variable for monetary policy in the euro area. We document the magnitude of revisions to euro area-wide data on output, prices, and money, and find that monetary aggregates have a potentially significant role in providing information about current real output. We then proceed to analyze the information content of money in a forward-looking model in which monetary policy is optimally determined subject to incomplete information about the true state of the economy. We show that monetary aggregates may have substantial information content in an environment with high variability of output measurement errors, low variability of money demand shocks, and a strong contemporaneous linkage between money demand and real output. As a practical matter, however, we conclude that money has fairly limited information content as an indicator of contemporaneous aggregate demand in the euro area.     

Financial systems and the cost channel transmission of monetary policy shocks

We study the role of financial systems for the cost channel transmission of monetary policy in a calibrated business cycle model. We characterize financial systems by the share of bank-dependent firms and by the degree of the pass-through from policy to bank lending rates, for which we provide empirical estimates for the euro area and the US. For plausible calibrations of the dynamics of the lending rate we find that the cost effects directly related to interest rate movements have only a limited effect on the transmission mechanism.     

THE TRANSMISSION OF THE MONETARY POLICY IN THE EURO AREA: THE ROLE OF THE BANKS’ BUSINESS MODEL

This paper sheds some new light on the incidence of the banks’ business model as a component of the bank lending channel in the euro area. Differently from existing literature, the analysis is led on the basis of the two main macroeconomic regions that today characterize the euro area: its north‐east (German‐centric) and south‐west halves. The observation period is 2008–2013, mainly featured by the financial and economic crisis. The empirical findings evidence that in the north‐east half of the euro area the cooperative banks leveraged the effects of the reduction in the interest rates in terms of new lending. In this respect, they differentiated from commercial and savings banks, which showed a more neutral impact on the transmission of the monetary policy decisions. These results highlight the distinctive role of the cooperative banks in terms of credit provision in Germany and in the whole north‐east half of the euro area. Nevertheless, this cooperative banking effect did not emerge for the south‐west half of the continent, particularly hit by the crisis. This may suggest that the bank's business model tend to be neutral to the transmission of the monetary policy in economies characterized by prolonged recessions.     

Credit ratings and bond spreads of the GIIPS

We examine the relationship between credit ratings and bond yield spreads of peripheral countries in the euro area (Greece, Ireland, Italy, Portugal and Spain) for the period 1995–2014. Since 2012, bond spreads of those countries have come down very fast, whereas credit ratings have hardly changed. Our results suggest that credit rating agencies have become more cautious and have changed their approach to assess credit risk of sovereigns, and that the impact of sovereign credit risk ratings on sovereign bond spreads has changed.     

The role of uncertainty in the euro crisis – an application of liquidity preference theory

The world financial crisis triggered a rediscovery of the active role fiscal policy can play as a remedy in such situations. During the euro crisis, escalating funding costs in a number of southern eurozone member states and Ireland have called this strategy into question. One interpretation of the euro crisis concentrated on the public debt trends in those countries. Opposing this view, the main point of this contribution is to elaborate the link between rising interest rates on sovereign bonds in the euro crisis and a major feature of the financial crisis – a subdued degree of investor confidence after the Lehman collapse. Theoretically, this link is developed with reference to Keynes’ liquidity preference theory. The high explanatory power of measures for the degree of confidence in financial markets as well as detrimental effects of fiscal austerity on the evolution of sovereign yield spreads are demonstrated empirically by means of panel regressions and supplementary correlation analyses.     

Financial conditions indexes for the United States and euro area

Financial conditions indexes are developed for the United States and euro area using a wide range of financial indicators and a dynamic factor model. The financial conditions indexes are shown to be useful for forecasting economic activity and have good revision properties. Variants of the indexes that allow for cross-economy effects reveal very strong financial linkages across the United States and euro area.     

欧元问世后国际储备货币竞争格局与欧元危机

欧元问世以来,国际储备货币竞争格局由美元垄断已经演化成美元与欧元的双头竞争。研究显示,造成欧元危机的真正原因是全球欧元储备份额的持续上升,它严重削弱了美元的全球霸权和美国的国家利益,欧元危机不是由债务国违约引发,而是由美国的评级机构调降这些国家的主权债务评级引发。本文认为,只要现存的国际储备货币体系仍然得以维持,欧元危机就不会导致欧元崩溃和欧元终结。     

Model uncertainty in Panel Vector Autoregressive models

We develop methods for Bayesian model averaging (BMA) or selection (BMS) in Panel Vector Autoregressions (PVARs). Our approach allows us to select between or average over all possible combinations of restricted PVARs where the restrictions involve interdependencies between and heterogeneities across cross-sectional units. The resulting BMA framework can find a parsimonious PVAR specification, thus dealing with overparameterization concerns. We use these methods in an application involving the euro area sovereign debt crisis and show that our methods perform better than alternatives. Our findings contradict a simple view of the sovereign debt crisis which divides the euro zone into groups of core and peripheral countries and worries about financial contagion within the latter group.     

Attitudes towards euro area reforms: Evidence from a randomized survey experiment

This paper provides insights into the determinants of euro area reform preferences by means of a randomized survey experiment in Germany. Respondents are confronted with a pro and a contra argument to reform proposals on a European Unemployment Benefit Scheme and a Sovereign Insolvency Procedure, respectively, with the contra argument being varied across respondents. Our results for the control group suggest that there is a low willingness to accept fiscal risk-sharing through common unemployment insurance, while a sovereign insolvency procedure aimed at strengthening market discipline is supported by a majority of the survey participants. Our randomized treatments highlighting specific potential adverse effects of the reforms lead to significant downward shifts in approval rates. Altruism, EU support, nationalism, political preferences and income are important predictors of support for the reform proposals. We also show that there is a striking contrast between the low level of support for transfers to other euro area member states and a broad acceptance of inner German transfers.
