Abstract
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.

Flow of Conjunctural Information and Forecast of Euro Area Economic Activity
Katja Drechsel, L. Maurin
Journal of Forecasting,
No. 3,
2011
Abstract
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.

Vigorous upswing continues
Wirtschaft im Wandel,
No. 3,
2011
Abstract
The worldwide upswing has gained momentum since last autumn. The main cause for the high growth dynamics is a monetary policy that is very expansive not only in advanced economies, where the utilization rates for production capacities are mostly still low, but also in emerging market economies that in general have already recovered from the Great Recession.
The German economy participates in the worldwide upswing. Here the recovery is ahead of those in most other advanced economies. Both exports and domestic demand are strongly expanding. One reason for the high growth dynamics is that key interest rates are particularly low for Germany, as the ECB has to take into account that many euro area economies are much more fragile. In addition, Germany still benefits from the wage moderation and the labour market reforms in the past decade: employment is expanding strongly, and firms find many profitable investment projects.
Major risks for this forecast are structural problems of some advanced economies that had become visible during the Great Recession and are still unresolved (concerning the US housing market and the crisis of confidence in the fiscal sustainability of some euro area countries in particular). A further risk is the possibility of further oil price hikes due to political instability in North Africa and the Middle East.

Inflation and Relative Price Variability in the Euro Area: Evidence from a Panel Threshold Model
Dieter Nautz, Juliane Scharff
Applied Economics,
No. 4,
2012
Abstract
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.).

Konjunktur aktuell: Aufschwung in Deutschland geht weiter – Krisenprävention und Krisenmanagement in Europa unter Reformdruck
Wirtschaft im Wandel,
No. 1,
2011
Abstract
We estimate that in 2010, the German GDP has expanded by 3.7%. In all probability, growth will continue in the two following years, with output rising by 2.3% in 2011 and by 1.7% in 2012. Thus, we see the recovery of the German economy after the Great Recession as a starting point for a strong upswing. In case the fiscal crisis of peripheral euro area countries intensified, however, or if confidence in the US dollar waned due to the extremely expansive policy in the US, expectations would quickly turn pessimistic. The key task for the European economic policy is improving its ability to manage and prevent financial and fiscal crises.
The recovery of the world economy continues. This is particularly true for the US, but for the European Union as well, in spite of drastic fiscal adjustment programs in Britain and Spain. In most of emerging markets economies, economic policy has been trying to dampen frothy upswings without damaging the high growth dynamics. As a consequence, growth slowed down in Asia after last spring. Leading indicators for China and India, however, point to an acceleration of economic activity during this winter. Neighboring economies, not least the Japanese, will soon benefit from higher exports.

Macroeconomic Challenges in the Euro Area and the Acceding Countries
Katja Drechsel
Dissertation, Online-Publikation,
2010
Abstract
The conduct of effective economic policy faces a multiplicity of macroeconomic challenges, which requires a wide scope of theoretical and empirical analyses. With a focus on the European Union, this doctoral dissertation consists of two parts which make empirical and methodological contributions to the literature on forecasting real economic activity and on the analysis of business cycles in a boom-bust framework in the light of the EMU enlargement. In the first part, we tackle the problem of publication lags and analyse the role of the information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A huge dataset of monthly indicators is used to estimate simple bridge equations. 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 find 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. In the second part, we focus on the potential accession of the new EU Member States in Central and Eastern Europe to the euro area. In contrast to the discussion of Optimum Currency Areas, we follow a non-standard approach for the discussion on abandonment of national currencies the boom-bust theory. We analyse whether evidence for boom-bust cycles is given and draw conclusions whether these countries should join the EMU in the near future. Using a broad range of data sets and empirical methods we document credit market imperfections, comprising asymmetric financing opportunities across sectors, excess foreign currency liabilities and contract enforceability problems both at macro and micro level. Furthermore, we depart from the standard analysis of comovements of business cycles among countries and rather consider long-run and short-run comovements across sectors. While the results differ across countries, we find evidence for credit market imperfections in Central and Eastern Europe and different sectoral reactions to shocks. This gives favour for the assessment of the potential euro accession using this supplementary, non-standard approach.

Vorteile einer niedrigen Inflationsrate: Empirische Ergebnisse für den Euroraum
Juliane Scharff
Wirtschaft im Wandel,
No. 10,
2010
Abstract
Der Vorschlag des Chefvolkswirts des Internationalen Währungsfonds, Olivier Blanchard, das Inflationsziel auf vier Prozent anzuheben, hat eine lebhafte Debatte über die angemessene Höhe der Zielinflationsrate entfacht. Dabei ist keineswegs offensichtlich, dass der durch höhere Inflationsraten größere Spielraum in Bezug auf Leitzinssenkungen in Krisenzeiten auch zu einem volkswirtschaftlichen Mehrwert führt. Insbesondere sind die mit einer höheren Inflationsrate einhergehenden volkswirtschaftlichen Kosten nicht zu vernachlässigen. So ist zum Beispiel die Variabilität der relativen Preise tendenziell umso größer, je höher die Inflationsrate ist. Dadurch wird die Signal-und Lenkungsfunktion relativer Preisänderungen beeinträchtigt, und dies hat negative Folgen für die effiziente Allokation von Ressourcen. Diese Studie untersucht im Rahmen einer empirischen Analyse den Einfluss der Inflation auf die Schwankungen der relativen Preise für den Euroraum. Sie kann einen signifikanten positiven Zusammenhang zwischen Inflation und Variabilität der relativen Preise feststellen. Damit liefert sie empirische Evidenz für einen störenden Einfluss von Inflation auf die relativen Preise und folglich für negative realwirtschaftliche Effekte von Inflation. Die Ergebnisse sprechen für eine Geldpolitik moderater Inflationsraten.
