The Laffer curve revisited
Mathias Trabandt, Harald Uhlig
Journal of Monetary Economics,
No. 4,
2011
Abstract
Laffer curves for the US, the EU-14 and individual European countries are compared, using a neoclassical growth model featuring “constant Frisch elasticity” (CFE) preferences. New tax rate data is provided. The US can maximally increase tax revenues by 30% with labor taxes and 6% with capital taxes. We obtain 8% and 1% for the EU-14. There, 54% of a labor tax cut and 79% of a capital tax cut are self-financing. The consumption tax Laffer curve does not peak. Endogenous growth and human capital accumulation affect the results quantitatively. Household heterogeneity may not be important, while transition matters greatly.

The Importance of Estimation Uncertainty in a Multi-Rating Class Loan Portfolio
Henry Dannenberg
IWH Discussion Papers,
No. 11,
2011
Abstract
This article seeks to make an assessment of estimation uncertainty in a multi-rating class loan portfolio. Relationships are established between estimation uncertainty and parameters such as probability of default, intra- and inter-rating class correlation, degree of inhomogeneity, number of rating classes used, number of debtors and number of historical periods used for parameter estimations. In addition, by using an exemplary portfolio based on Moody’s ratings, it becomes clear that estimation uncertainty does indeed have an effect on interest rates.

Ostdeutsche Wirtschaft im Jahr 2011: Trotz Wachstumsbeschleunigung keine Fortschritte im gesamtwirtschaftlichen Aufholprozess
Die ostdeutsche Wirtschaft schlägt in diesem Jahr ein höheres Wachstumstempo als im Jahr nach der Krise an. Während das bislang vom Export getriebene Erholungsmuster die Ausrichtung der ostdeutschen Produktion auf die Güternachfrage im Inland weniger ansprach und der Anstieg des Bruttoinlandsproduktes (BIP) von 2% im vergangenen Jahr deutlich hinter der deutschlandweiten Rate von 3,6% zurückblieb, wird sich das Wachstum im Jahr 2011 auf 2,8% beschleunigen. Ausschlaggebend ist der Wechsel der Auftriebskräfte in Deutschland auf die Nachfrage nach Investitions- und nach Konsumgütern. Treibende Kraft bleibt die Industrie, die bereits 2010 dank der Integration in die gesamtdeutschen Wertschöpfungsketten fast so kräftig zulegte wie in Westdeutschland. In diesem Jahr kommen jedoch auch das Baugewerbe und die konsumnahen Dienstleistungsbereiche in Schwung.

What Might Central Banks Lose or Gain in Case of Euro Adoption – A GARCH-Analysis of Money Market Rates for Sweden, Denmark and the UK
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 9,
2011
Abstract
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.

Competition, Risk-shifting, and Public Bail-out Policies
Reint E. Gropp, H. Hakenes, Isabel Schnabel
Review of Financial Studies,
No. 6,
2011
Abstract
This article empirically investigates the competitive effects of government bail-out policies. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the impact of this variable on banks' risk-taking behavior, using a large sample of banks from OECD countries. Our results suggest that government guarantees strongly increase the risk-taking of competitor banks. In contrast, there is no evidence that public guarantees increase the protected banks' risk-taking, except for banks that have outright public ownership. These results have important implications for the effects of the recent wave of bank bail-outs on banks' risk-taking behavior.

Ostdeutsche Wirtschaft im Sog der anziehenden Binnenkonjunktur
Mit der Verlagerung der konjunkturellen Auftriebskräfte in Deutschland auf die inländische Nachfrage nach Investitions- und Konsumgütern haben sich die Wachstumschancen der ostdeutschen Wirtschaft deutlich aufgehellt. Nach der Prognose des Instituts für Wirtschaftsforschung Halle (IWH) wird das Bruttoinlandsprodukt in diesem Jahr mit einer Rate von 2,8% stärker zunehmen als im Jahr zuvor (2%). Zwar dürfte die Aufwärtsdynamik damit ein weiteres Jahr hinter der in Deutschland insgesamt (3,6%) zurückbleiben, der Abstand verringert sich allerdings deutlich. Neben der zunehmenden Stärkung der Binnennachfrage gehen in diesem Jahr noch kräftige Impulse vom Export aus, wenngleich sie im Verlauf abnehmen. Davon zehrt die ostdeutsche Wirtschaft aufgrund der geringen direkten Ausrichtung auf die Exportmärkte weniger stark als die westdeutsche.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
North American Journal of Economics and Finance,
No. 3,
2011
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Extreme Risks in Financial Markets and Monetary Policies of the Euro-candidates
Hubert Gabrisch, Lucjan T. Orlowski
Comparative Economic Studies,
No. 4,
2011
Abstract
This study investigates extreme tail risks in financial markets of the euro-candidate countries and their implications for monetary policies. Our empirical tests show the prevalence of extreme risks in the conditional volatility series of selected financial variables, that is, interbank rates, equity market indexes and exchange rates. We argue that excessive instability of key target and instrument variables should be mitigated by monetary policies. Central banks in these countries will be well-advised to use both standard and unorthodox (discretionary) tools of monetary policy while steering their economies out of the financial crisis and through the euro-convergence process.

The Impact of Fixed Exchange Rates on Fiscal Discipline
Makram El-Shagi
Scottish Journal of Political Economy,
No. 5,
2011
Abstract
In this paper, it is shown that, contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004 and uses various estimation techniques for dynamic panel data, in particular a GMM estimation in the tradition Arellano and Bover (1995) and Blundell and Bond (1998). Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.
