Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks
Stefan Eichler, Alexander Karmann
Open Economies Review,
No. 5,
2011
Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Rules versus Discretion in Loan Rate Setting
Geraldo Cerqueiro, Hans Degryse, Steven Ongena
Journal of Financial Intermediation,
No. 4,
2011
Abstract
Loan rates for seemingly identical borrowers often exhibit substantial dispersion. This paper investigates the determinants of the dispersion in interest rates on loans granted by banks to small and medium sized enterprises. We associate this dispersion with the loan officers’ use of “discretion” in the loan rate setting process. We find that “discretion” is most important if: (i) loans are small and unsecured; (ii) firms are small and opaque; (iii) the firm operates in a large and highly concentrated banking market; and (iv) the firm is distantly located from the lender. Consistent with the proliferation of information-technologies in the banking industry, we find a decreasing role for “discretion” over time in the provision of small credits to opaque firms. While widely used in the pricing of loans, “discretion” plays only a minor role in the decisions to grant loans.

Modelling Country Default Risk as a Latent Variable: A Multiple Indicators Multiple Causes Approach
A. Bühn, Stefan Eichler, Dominik Maltritz
Applied Economics,
No. 36,
2012
Abstract
We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.

Bank-specific Shocks and the Real Economy
Claudia M. Buch, Katja Neugebauer
Journal of Banking and Finance,
No. 8,
2011
Abstract
Governments often justify interventions into the financial system in the form of bail outs or liquidity assistance with the systemic importance of large banks for the real economy. In this paper, we analyze whether idiosyncratic shocks to loan growth at large banks have effects on real GDP growth. We employ a measure of idiosyncratic shocks which follows Gabaix (forthcoming). He shows that idiosyncratic shocks to large firms have an impact on US GDP growth. In an application to the banking sector, we find evidence that changes in lending by large banks have a significant short-run impact on GDP growth. Episodes of negative loan growth rates and the Eastern European countries in our sample drive these results.

East German economy in 2011: Despite overall Economic Growth no Progress in Catching Up
Udo Ludwig, Hans-Ulrich Brautzsch, Franziska Exß, Brigitte Loose
Wirtschaft im Wandel,
No. 7,
2011
Abstract
Die ostdeutsche Wirtschaft schlägt in diesem Jahr ein höheres Wachstumstempo an als im Jahr nach der Krise. 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 Wert-schöpfungsketten fast so kräftig zulegte wie in Westdeutschland. In diesem Jahr kommen jedoch auch das Baugewerbe und die konsumnahen Dienstleistungsbereiche in Schwung.

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.

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.
