Exchange rate bands of inaction and play-hysteresis in Greek exports to the Euro Area,the US and Turkey: sectoral evidence

In this paper a non-linear model is applied, where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction, which we call “play” area—analogous to mechanical play. We implement an algorithm describing path-dependent play-hysteresis into a regression framework. The hysteretic impact of real exchange rates on Greek exports is estimated based on the period from 1995Q1 to 2014Q4. Looking at some of the main export partners of Greece, the euro area, Turkey and the US, and some of its most important tradeable sectors we identify significant hysteretic effects for a part of the Greek exports. We find that Greek export activity is characterized by “bands of inaction” with respect to changes in the real exchange rate and calculate the further real depreciation needed to trigger a spurt in Greek exports. To check for robustness we (a) estimate Greek export equations for a limited sample excluding the recent financial crisis, (b) use export weight instead of deflated nominal exports as the dependent variable, (c) employ a political uncertainty variable as a determinant of the width of the area of weak reaction. Overall, we find that those specifications which take uncertainty into account display the best goodness of fit. In other words: the option value of waiting dominates the real exchange rate effect on Greek exports.     

EXCHANGE RATE BANDS OF INACTION AND PLAY‐HYSTERESIS IN GERMAN EXPORTS—SECTORAL EVIDENCE FOR SOME OECD DESTINATIONS

A non‐linear model is applied, where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction, which we call ‘play’ area—analogous to mechanical play. We implement an algorithm describing path‐dependent play‐hysteresis into a regression framework. The hysteretic impact of real exchange rates on German exports is estimated based on the period from 1995Q1 to 2010Q3. Looking at some of the main export partners of Germany outside the euro area and some of the most important tradeable sectors we find significant hysteretic effects for a part of the German exports.     

A more effective euro area monetary policy than OMTs — gold-backed sovereign debt

Given the shortcomings of the current responses to the sovereign debt crisis in the eurozone, the author proposes utilising national gold reserves as collateral for government debt. Gold backing would be quite attractive to bond investors and would significantly ease the burden of high sovereign debt yields, particularly in Portugal and Italy. Moreover, it would achieve this without adding further risky assets to the European Central Bank’s balance sheet and thereby transferring credit risk to Northern European countries.     

US–Euro Area Monetary Policy Interdependence: New Evidence from Taylor Rule‐based VECMs

(1227) Ansgar Belke and Yuhua Cui This paper analyses the monetary policy interdependence between the European Central Bank (ECB) and the Federal Reserve (Fed) for the period 1999–2006. Two models are specified: a partial vector error correction model (VECM) and a general VECM. In the partial VECM, we look for a long‐run interdependent relationship between the interest rates of the two currency areas and specify the Taylor Rule terms as exogenous variables. In the general VECM, we regard all variables as endogenous, and look for long‐run equilibrium relationships among them, which may reveal monetary policy interdependence between the two central banks. Weak exogeneity is checked in both models in order to establish a possible leader–follower relationship. The empirical results of both models indicate interdependence between the ECB and the Fed, but only the general VECM testifies a leader–follower pattern between the two central banks. According to this pattern, the ECB does follow the Fed.     

Das zweite Rettungspaket für Griechenland

Ende Juli haben die Euro-Regierungschefs ein zus?tzliches sehr umfangreiches Rettungspaket für Griechenland beschlossen. Der EU-Gipfel konnte die M?rkte allerdings nicht beruhigen. Diese entt?uschende Reaktion heizt die Diskussion auf politischer Ebene, aber auch in der Wirtschaftswissenschaft weiter an. Wie ist die Beteiligung des Privatsektors an der Krisenbew?ltigung zu bewerten? Wie stark wird der Steuerzahler belastet? Was ist von Eurobonds oder einer europ?ischen Wirtschaftsregierung mit weitreichenden Kompetenzen zu halten? Mit diesen Fragen besch?ftigen sich die Autoren der folgenden Aufs?tze.     

Asymmetric shocks and EMU: Is there a need for a stability fund?

A recent report by the European Parliament looks into questions relating to the likelihood of asymmetric shocks under EMU, the system's ability to absorb them and the need for new instruments and mechanisms. Our authors evaluate the report and qualify it on some important accounts, adding a proposal of their own on how to cope with unanticipated and asymmetric regional shocks in the euro area. The article is an extended version of the comment by the first author on the Explanatory Statement “Asymmetric Shock or Shock Specific to One Country”, Public Expert Hearing, Subcommittee on Monetary Affairs of the European Parliament, Brussels, 2^nd September 1998.     

Schuldenkrise in der Europäischen Union

Die Krise Griechenlands w?chst sich zu einer Gefahr für den gesamten Euroraum aus. Wie soll die Europ?ische Union darauf reagieren? Sie befindet sich im Dilemma zwischen Bailout und Bestrafung des „Defizitsünders“. Das erste scheint für den Bestand der W?hrungsunion unvermeidlich, das zweite ist erforderlich, um einen Moral Hazard zu vermeiden.     

Modelling and Forecasting Gas Flow on Exits of Gas Transmission Networks

The flow of natural gas within a gas transmission network is studied with the aim to optimize such networks. The analysis of real data provides a deeper insight into the behaviour of gas in‐ and outflow. Several models for describing dependence between the maximal daily gas flow and the temperature on network exits are proposed. A modified sigmoidal regression is chosen from the class of parametric models. As an alternative, a semi‐parametric regression model based on penalized splines is considered. The comparison of models and the forecast of gas loads for very low temperatures based on both approaches is included. The application of the obtained results is discussed.     

Specialisation patterns and the synchronicity of regional employment cycles in Europe

This paper examines the degree of correlation, i.e. the synchronicity, among EU regional employment cycles and attempts to link it to changing patterns of specialisation. This topic deserves attention since the existing evidence seems to suggest a rather limited role for a region’s industry structure in explaining its employment growth. A dynamic panel data model is estimated for pairs of regions by within groups, i.e., by a standard fixed effects estimator. The results indicate that synchronicity between regions has declined and differences in regional industry structure can be held account for this.
