This study deals with the question whether the central banks of Sweden, Denmark and the UK can really influence short-term money markets and thus, would lose this influence in case of Euro adoption. We use a GARCH-M-GED model with daily money market rates. The model reveals the co-movement between the Euribor and the shortterm interest rates in these three countries. A high degree of co-movement might be seen as an argument for a weak impact of the central bank on its money markets. But this argument might only hold for tranquil times. Our approach reveals, in addition, whether there is a specific reaction of the money markets in turbulent times. Our finding is that the policy of the European Central Bank (ECB) has indeed a significant impact on the three money market rates, and there is no specific benefit for these countries to stay outside the Euro area. However, the GARCH-M-GED model further reveals risk divergence and unstable volatilities of risk in the case of adverse monetary shocks to the economy for Sweden and Denmark, compared to the Euro area. We conclude that the danger of adverse monetary developments cannot be addressed by a common monetary

policy for these both countries, and this can be seen as an argument to stay outside the Euro area.

The worldwide upswing has lost momentum, but it will overcome the present slowdown. Monetary policy is overall still accommodative, and growth dynamics continue to be high in emerging market countries. For the euro area, we expect GDP to grow by around 1.9% in 2011 and 1.7% in 2012, not enough to bring the unemployment rate back significantly below 10%. In fact, in a large core region of the euro area the upswing is well under way; this region includes, apart from Germany and some smaller economies, France, Belgium and the Netherlands. However, the crisis of confidence in the ability of EU institutions to master the fiscal crises is a major threat to the continuation of the upswing.

Am 14. und 15. Februar 2011 fand am IWH erstmalig in Zusammenarbeit mit dem International Network for Economic Research (INFER) der Workshop „Applied Economics and Economic Policy“ statt. Wissenschaftlerinnen und Wissenschaftler europäischer Universitäten und internationaler Organisationen stellten einem breiten Publikum neueste Forschungsergebnisse zu aktuellen ökonomischen Fragen und Problemen vor. Der Workshop richtete sich neben einem wissenschaftlichen Publikum vor allem auch an Mitarbeiterinnen und Mitarbeiter internationaler Organisationen, wie beispielsweise der Europäischen Kommission und der Europäischen Zentralbank (EZB), sowie der verschiedenen Ministerien, wie z. B. der Wirtschaftsministerien. Ziel der Veranstaltung war es somit, nicht nur aktuelle Forschungsergebnisse vorzustellen, sondern auch mit Vertretern aus Wissenschaft und Praxis über aktuelle Wirtschaftspolitik und über das Spezialthema „The Empirics of Imbalances and Disequilibria“

zu diskutieren. Mit Lorenzo Bini Smaghi, Mitglied des Direktoriums der EZB, und Martin Hallet aus der Generaldirektion Wirtschaft und Finanzen der Europäischen Kommission konnten zwei hochrangige Vertreter aus den politischen Institutionen als Keynote-Speaker gewonnen werden.

Combining forecasts, we analyse the role of information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A dataset of 114 monthly indicators is set up and simple bridge equations are estimated. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We found that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. Compared to an AR forecast, these improve by more than 40% the forecast performance for GDP in the current and next quarter.

Our baseline scenario for the world economy in 2011 and 2012 is a continuation of the upswing, because growth dynamics continue to be high in emerging economies, monetary policy will in general continue to be expansive, and the factors that dampen the recovery in many advanced economies are slowly declining. There are two main downward risks for this prospect: first, low interest rates and high growth might drive commodity prices to disruptive levels. Second, waning confidence in financial markets might enhance volatility and enforce further extensivemeasures of consolidation in advanced economies.

The impact of inflation on Relative Price Variability (RPV) generates an important channel for real effects of inflation. This article provides first evidence on the empirical relation between inflation and RPV in the euro area. Stirred by the widespread use of inflation caps or target bands in monetary policy practice, we are particularly interested in threshold effects of inflation. In line with the predictions of monetary search models, our results indicate that expected inflation significantly increases RPV only if inflation is either very low (below 0.95% per annum (p.a.)) or very high (above 4.96% p.a.).

This paper analyzes the process of real economic convergence in the New Member States (NMS) bein g formerly centrally planned economies, using nonparametric methods instead of conventional parametric measurement tools like beta and sigma models. This methodological framework allows the examining of the relative income distribution in different periods of time, the number of modes of the density distribution, the existence of “convergence clubs” in the distribution and the hypothesis of convergence at a single point in time. The modality tests (e.g. the ASH-WARPing procedure) and stochastic kernel are nonparametric techniques used in the empirical part of the study to examine the income distribution in the NMS area. Additionally, random effects panel regressions are used, but only for comparison reasons. The main findings of the paper are the bimodality of the income density distribution over time and across countries, and the presence of convergence clubs in the income distribution from 1995 to 2008. The findings suggest a lack of absolute convergence in the long term (1995-2008) and also when looking only from 2003 onwards. The paper concludes that, in comparison with the parametrical approach, the nonparametric one gives a deeper, real and richer perspective on the process of real convergence in the NMS area.

Das deutsche Bruttoinlandsprodukt steigt im Jahr 2010 preisbereinigt um 3,7%. Es ist sehr wahrscheinlich, dass sich der Aufschwung in den beiden kommenden Jahren fortsetzen wird und das reale Bruttoinlandsprodukt 2011 um 2,3% und 2012 um 1,7% zulegt. Damit gelingt es der deutschen Wirtschaft, den Aufholprozess nach der weltweiten Finanzkrise als Startrampe für den Aufschwung zu nutzen. Käme es jedoch zu einer weiteren Zuspitzung der europäischen Schulden- und Vertrauenskrise oder wegen der äußerst expansiven Wirtschaftspolitik in den USA zu einem Verlust des Vertrauens in den US-Dollar, würde dies die konjunkturellen Erwartungen erheblich dämpfen. Entscheidend ist jetzt, dass die europäische Wirtschaftspolitik Krisenprävention und Krisenmanagement nachhaltig verbessert.

Die weltwirtschaftliche Erholung setzt sich fort. Die Produktion stieg in den fortgeschrittenen Volkswirtschaften bis in den Herbst 2010 hinein weiter, in den USA sogar wieder etwas beschleunigt. Auch in der Europäischen Union nahm die Produktion deutlich zu – trotz der irischen Krise und umfangreicher Sparpakete in Großbritannien und Spanien. In den meisten Schwellenländern bemühte sich die Wirtschaftspolitik schon das ganze Jahr über, eine Überhitzung zu verhindern, ohne die vielfach hohe Wachstumsdynamik zu beschädigen. Auch deswegen hat sich der Aufschwung insbesondere in Asien seit dem Frühjahr verlangsamt. Für die Wachstumszentren China und Indien sprechen aber Stimmungsindikatoren wieder für ein Anziehen der Konjunktur im Winterhalbjahr. Davon dürften die Nachbarländer, etwa die zuletzt wieder schwächelnde Konjunktur in Japan, profitieren.
