Transmission of uncertainty shocks: learning from heterogeneous responses on a panel of EU countries
Claeys, Peter ; Vašíček, Bořek
Numerous recent studies, starting with Bloom (2009), highlight the impact of varying uncertainty levels on economic activity. These studies mostly focus on individual countries, and cross-country evidence is scarce. In this paper, we use a set of (panel) BVAR models to study the effect of uncertainty shocks on economic developments in EU Member States. We explicitly distinguish between domestic, common and global uncertainty shocks and employ new proxies of uncertainty. The domestic uncertainty indicators are derived from the Business and Consumer Surveys administered by the European Commission. The common EU-wide uncertainty is subsequently derived by means of a factor model. Finally, the global uncertainty indicator – inspired by Jurado et al. (2015) – is extracted as a common factor from a broad set of forecast indicators that are not driven by the business cycle. The results suggest that real output in EU countries drops after spikes in uncertainty, mainly as a result of lower investment. Unlike for the U.S., there is little evidence of activity overshooting following this initial fall. The responses to uncertainty shocks vary across Member States. These differences can be attributed not mainly to different shock sizes, but rather to cross-country structural characteristics. Member States with more flexible labour markets and product markets seem to weather uncertainty shocks better. Likewise, a higher manufacturing share and higher economic diversification help dampen the impact of uncertainty shocks. The role of economic openness is more ambiguous.

Banking and Currency Crises: Differential Diagnostics for Developed Countries
Joy, Mark ; Rusnák, Marek ; Šmídková, Kateřina ; Vašíček, Bořek
We identify a set of “rules of thumb” that characterise economic, financial and structural conditions preceding the onset of banking and currency crises in 36 advanced economies over 1970–2010. We use the Classification and Regression Tree methodology (CART) and its Random Forest (RF) extension, which permits the detection of key variables driving binary crisis outcomes, allows for interactions among key variables and determines critical tipping points. We distinguish between basic country conditions, country structural characteristics and international developments. We find that crises are more varied than they are similar. For banking crises we find that low net interest rate spreads in the banking sector and a shallow or inverted yield curve are their most important forerunners in the short term, whereas in the longer term it is high house price inflation. For currency crises, high domestic short-term rates coupled with overvalued exchange rates are the most powerful short-term predictors. We find that both country structural characteristics and international developments are relevant banking crisis predictors. Currency crises, however, seem to be driven more by country idiosyncratic, short-term developments. We find that some variables, such as the domestic credit gap, provide important unconditional signals, but it is difficult to use them as conditional signals and, more importantly, to find relevant threshold values.

Spillover of the ECB's Monetary Policy Outside the Euro Area: How Different is Conventional From Unconventional Policy?
Babecká Kucharčuková, Oxana ; Claeys, Peter ; Vašíček, Bořek
This paper studies the macroeconomic impact of ECB policy on the euro area and six non-EMU countries. The analysis is based on the evolution of a synthetic index of overall euro area monetary conditions (MCI) that can be decomposed into conventional and unconventional policy measures. A standard monetary VAR including the MCI subcomponents shows that the transmission of unconventional monetary policy in the euro area is quite different than under conventional policy: prices react quickly, but the response of output (industrial production) is muted. A block-restricted VAR analysis confirms that euro area monetary policy spills over to the macroeconomic developments of non-EMU countries. While conventional monetary policy has a generalised effect on economic activity, exchange rates and prices, unconventional measures have generated a variety of responses. Exchange rates respond rather quickly, but an effect on the real economy is found only for some countries, and inflation remains largely unaffected.

The Exchange Rate as an Instrument at Zero Interest Rates: The Case of the Czech Republic
Franta, Michal ; Holub, Tomáš ; Král, Petr ; Kubicová, Ivana ; Šmídková, Kateřina ; Vašíček, Bořek
This study examines the use of the exchange rate by the Czech National Bank as a monetary policy instrument at the zero lower bound on interest rates. It provides a review of the economic literature on unconventional monetary policy instruments and particularly on the possibility of using the exchange rate. It explains the CNB’s reasons for further easing monetary policy and for choosing the exchange rate instrument and its specific level, and discusses its expected benefits in the case of the Czech Republic. It also explains why the CNB ultimately decided to transparently declare a one-sided exchange rate commitment with potentially unlimited foreign exchange interventions. The article concludes by assessing the impacts of the exchange rate weakening on the Czech economy to date, as compared to what the CNB had expected, and by describing the public debate of the CNB’s action and related changes in its communication strategy.

Inflation and the Steeplechase Between Economic Activity Variables
Baxa, Jaromír ; Plašil, Miroslav ; Vašíček, Bořek
A sharp increase in unemployment accompanied by a relatively muted response of inflation during the Great Recession cast further doubts on the validity of the Phillips curve. With the aid of dynamic model averaging (Raftery et al., 2010), this paper aims to highlight that the existence of a systemic relation between real activity and inflation is blurred due to (i) the failure to capture inflationary pressures by means of a single measure of economic activity, and (ii) the existence of a non-linear response of inflation to the driving variable. Based on data for the U.S. and other G7 countries, our results show that the relation between economic activity and inflation is quite sturdy when one allows for more complex assessment of the former. We find that inflation responds to different measures of economic activity across time and space, and no measure of economic activity clearly dominates. The output gap is often outperformed by unemployment-related variables such as the short-term unemployment rate, the unemployment expansion gap, and the unemployment recession gap. Finally, our results confirm a weakening of the inflation–activity relationship (i.e., a flattening of the Phillips curve) in the last decades, which might be attributed to structural changes in the economy and monetary policy, that is robust both across activity measures and across countries.

Short-Term Determinants of the Idiosyncratic Sovereign Risk Premium: A Regime-Dependent Analysis for European Credit Default Swaps
Calice, Giovanni ; Miao, RongHui ; Štěrba, Filip ; Vašíček, Bořek
This study investigates the dynamic behavior of the sovereign CDS term premium for a group of European countries. The CDS term premium can be regarded as a forward- looking measure of idiosyncratic sovereign default risk as perceived by financial markets in real time. Using a Markov-switching unobserved component model, we decompose the daily CDS term premium into two unobserved components of statistically different nature (stationary and nonstationary) and study the determinants of their short-term dynamics. Specifically, we link these components in a vector autoregression to various daily observed financial market variables. We find that decomposition into the two components is vital for understanding the short-term dynamics of the entire CDS term premium. The strongest impacts can be attributed to CDS market liquidity, local stock returns, and overall risk aversion. By contrast, the impact of shocks from the sovereign bond market is rather muted. Therefore, the CDS market microstructure effect and investor sentiment play the main roles in sovereign risk evaluation in real time. Moreover, our results suggest that the response of the CDS term premium to shocks to financial variables is regime-dependent and can be ten times stronger during periods of high volatility.

Measuring Sovereign Bond Spillover in Europe and the Impact of Rating News
Claeys, Peter ; Vašíček, Bořek
Although there is by now strong evidence that sovereign risk premia are driven by a common factor, little is known about the detailed linkages between sovereign bond markets. We employ the VAR method by Diebold and Yilmaz (2009) to analyse the strength and direction of bilateral linkages between EU sovereign bond markets using daily data on sovereign bond yield spreads and a common factor. The forecast-error variance decomposition of this FAVAR indicates a lot of heterogeneity in the bilateral spillover sent and received between bond markets. Spillover is more important than domestic factors for all eurozone countries. The CE countries mostly affect each other. Only Denmark, Sweden and the UK are rather insulated from spillover. The spillover has increased substantially since 2007, despite starting from a high level. We use this framework to measure the impact of sovereign rating news and analyse the dynamic linkages between spreads and the ratings of the main credit rating agencies. We find a two-sided relation between rating news and sovereign risk premia. The spillover of rating news is very heterogeneous, and it is substantially stronger for downgrades at lower grades. The impact is often weaker domestically than on bond spreads of other sovereigns. JEL

Is monetary policy in the new EU member states asymmetric?
Vašíček, Bořek
This paper tests whether monetary policy can be described as asymmetric in three new European Union (EU) members (the Czech Republic, Hungary, and Poland), which apply an inflation targeting regime. Two different empirical frameworks are used: (i) Generalized Method of Moments (GMM) estimation of models that allow discrimination between sources of potential policy asymmetry but are conditioned by specific underlying relations, and (ii) a flexible framework of sample splitting where nonlinearity enters via a threshold variable and monetary policy is allowed to switch between regimes.
