Abstract
In this paper we develop an open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model -- the Halle Economic Projection Model (HEPM) -- is closely related to studies published by Carabenciov et al. Our main contribution is that we model the Euro area countries separately. In doing so, we consider Germany, France, and Italy which represent together about 70 percent of Euro area GDP. The model combines core equations of the New-Keynesian standard DSGE model with empirically useful ad-hoc equations. We estimate this model using Bayesian techniques and evaluate the forecasting properties. Additionally, we provide an impulse response analysis and a historical shock decomposition.

IWH-Flash-Indikator: I. und II. Quartal 2012
Katja Drechsel
IWH Flash Indicator,
No. 1,
2012
Abstract
Der IWH-Flash-Indikator prognostiziert für die erste Jahreshälfte 2012 eine leichte konjunkturelle Belebung nach der Schwächephase Ende 2011. So zeigt der Indikator für das erste Quartal 2012 bereits wieder eine geringe Zunahme des preisbereinigten Bruttoinlandsproduktes in Deutschland von 0,1% gegenüber dem Vorquartal an. Im zweiten Quartal 2012 wird der Zu-wachs wohl 0,3% betragen.

Konjunktur aktuell: Europäische Schulden- und Vertrauenskrise bringt deutsche Konjunktur ins Stocken
Wirtschaft im Wandel,
No. 1,
2012
Abstract
Zur Jahreswende 2011/2012 hat die weitere Zuspitzung der Schulden- und Vertrauenskrise im Euroraum die weltwirtschaftlichen Aussichten deutlich eingetrübt. Auch Deutschland wird sich von der Verschlechterung der internationalen Konjunktur nicht abkoppeln können, und das deutsche Bruttoinlandsprodukt dürfte im Jahr 2012 mit 0,3% nur schwach zunehmen. Darüber hinaus sind die Risiken groß. Sollten etwa die Refinanzierungskosten im deutschen Bankensystem, anders als in dieser Prognose unterstellt, stark zunehmen, würde die gesamtwirtschaftliche Produktion 2012 wohl schrumpfen. Zentrale Aufgabe der Wirtschaftspolitik ist es gegenwärtig, das Vertrauen der Finanzmärkte in die Staatsfinanzen der Euroraum-Länder zu kräftigen. Von den Vorschlägen dafür, wie dies gelingen soll, verspricht der vom Sachverständigenrat vorgeschlagene Schuldentilgungspakt den besten Erfolg.

The Financial Crisis from a Forecaster's Perspective
Katja Drechsel, Rolf Scheufele
Kredit und Kapital,
No. 1,
2012
Abstract
This paper analyses the recession in 2008/2009 in Germany. This recession is very different from previous recessions in particular regarding their causes and magnitude. We show to what extent forecasters and forecasts based on leading indicators fail to detect the timing and the magnitude of the recession. This study shows that large forecast errors for both expert forecasts and forecasts based on leading indicators resulted during this recession which implies that the recession was very difficult to forecast. However, some leading indicators (survey data, risk spreads, stock prices) have indicated an economic downturn and hence, beat univariate time series models. Although the combination of individual forecasts provides an improvement compared to the benchmark model, the combined forecasts are worse than several individual models. A comparison of expert forecasts withthe best forecasts based on leading indicators shows only minor deviations. Overall, the range for an improvement of expert forecasts in the crisis compared to indicator forecasts is small.

Protect and Survive? Did Capital Controls Help Shield Emerging Markets from the Crisis?
Makram El-Shagi
Economics Bulletin,
No. 1,
2012
Abstract
Using a new dataset on capital market regulation, we analyze whether capital controls helped protect emerging markets from the real economic consequences of the 2009 financial and economic crisis. The impact of the crisis is measured by the 2009 forecast error of a panel state space model, which analyzes the business cycle dynamics of 63 middle-income countries. We find that neither capital controls in general nor controls that were specifically targeted to derivatives (that played a crucial role during the crisis) helped shield economies. However, banking regulation that limits the exposure of banks to global risks has been highly successful.

No. 11,
2011
Abstract
In 2011 the employment situation in East Germany has again improved. Approximately half of the employment growth is attributable to the industry (incl. construction). Registered unemployment declined considerably. Labor supply decreased like in recent years. In forecasting horizon the number of employees subject to social insurance will still increase despite of lower economic growth. The unemployment rate will amount to 11.0% in 2011 and to 10.9% in 2012.

Cluster Policies in the Federal States of Bavaria and Thuringia: Discrepancies between Practice and Theory
Gerhard Heimpold
Wirtschaft im Wandel,
No. 10,
2011
Abstract
The contribution analyzes cluster policies pursued in the Federal States of Bavaria and Thuringia. The investigation is based on the exploration of government documents. In both countries cluster policy is target at strengthening competitiveness. The documents explored do not reveal an economic justification for cluster policy in the sense of eliminating market failures, e. g. externalities, information asymmetries and coordination failures. Therefore, it is unclear whether the support schemes under consideration really tie in with factors that hamper cluster evolution. Policies in both states support state-wider clusters and networks. The state-wide focus, however, might undervalue advantages of spatial proximity. As another critical point the ex-ante selection of industries or technologies eligible under cluster policy can be regarded. Despite readiness of considering new technologies etc., public administration generally suffers from a lack of information about the future development perspectives of industries and technologies. A way to mitigate the limited capability of public administration in terms of forecasting might be favoring economic support based on competition for the best concepts/projects instead of focusing on certain industries. Several support schemes offered by the Federal government in Germany are already competition-based. In Thuringia cluster policy is strongly motivated by several structural shortcomings, e. g. by the fragmented firm landscape mainly consisting of small units. Therefore, beyond cluster policy, the necessity will remain to abolish directly the structural shortcomings mentioned, especially by providing an economic environment that enhances firm growth.

Europäische Schuldenkrise belastet deutsche Konjunktur: Gemeinschaftsdiagnose Herbst 2011
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Technologie,
2011
Abstract
Im Sommer 2011 haben sich die Aussichten für die Weltwirtschaft deutlich verschlechtert. Insbesondere droht in Europa die Staatsschuldenkrise sich zu einer Bankenkrise auszuweiten. Dies belastet zunehmend auch die deutsche Konjunktur. Die stark erhöhte Unsicherheit wird die inländische Nachfrage dämpfen, und der Außenhandel dürfte aufgrund der schwierigen Lage wichtiger Handelspartner nicht mehr zur Expansion beitragen. Die Institute erwarten, dass das Bruttoinlandsprodukt in diesem Jahr um 2,9 % und im kommenden lediglich um 0,8 % zunimmt. Die Arbeitslosenquote dürfte nur noch wenig zurückgehen von 7,0 % auf 6,7 % im Jahr 2012. Die Inflationsrate von voraussichtlich 2,3 % im Jahr 2011 und 1,8 % im Jahr 2012 wird mehr und mehr vom inländischen Preisauftrieb bestimmt. Das Budgetdefizit des Staates wird auf 0,9 % in Relation zum Bruttoinlandsprodukt in diesem Jahr und auf 0,6 % im kommenden Jahr zurückgehen.
