Abstract
We investigate credit risk co-movements and contagion in sovereign debt markets of 17 industrialized countries for the period 2008-2012. We use dynamic conditional correlations of sovereign CDS spreads to detect contagion. This approach allows separating the channels through which contagion occurs from the determinants of simple interdependence. The results show that, first, sovereign credit risk comoves considerably, in particular among eurozone countries and during the sovereign debt crisis. Second, contagion cannot be attributed to one moment in time but varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking, and common market sentiment constitute the main channels of contagion.

Initial Evidence from a New Database on Capital Market Restrictions
Makram El-Shagi
Panoeconomicus,
No. 3,
2012
Abstract
One of the key obstacles to the empirical analysis of capital controls has been the unavailability of a detailed set of indicators for controls that cover a broad set of countries over a range of years. In this paper, we propose a new set of indicators derived from the Annual Reports on Exchange Arrangements and Export Restrictions. Contrary to most earlier attempts to construct control indicators from this source, our set of indices allows one to analyze the control intensity separately for inflow, outflow and repatriation controls. An additional set of indicators features information on the institutional design of controls. At first glance, the data show that the financial crisis caused a surge in capital market restrictions, most notably concerning the derivatives market. This reflex, which is not justified by the scarce empirical evidence on the success of controls, shows the importance of having a valid measure to allow an econometrically sound policy evaluation in this field. The data are available from the author upon request.

Spillover Effects among Financial Institutions: A State-dependent Sensitivity Value-at-Risk Approach
Z. Adams, R. Füss, Reint E. Gropp
Abstract
In this paper, we develop a state-dependent sensitivity value-at-risk (SDSVaR) approach that enables us to quantify the direction, size, and duration of risk spillovers among financial institutions as a function of the state of financial markets (tranquil, normal, and volatile). Within a system of quantile regressions for four sets of major financial institutions (commercial banks, investment banks, hedge funds, and insurance companies) we show that while small during normal times, equivalent shocks lead to considerable spillover effects in volatile market periods. Commercial banks and, especially, hedge funds appear to play a major role in the transmission of shocks to other financial institutions. Using daily data, we can trace out the spillover effects over time in a set of impulse response functions and find that they reach their peak after 10 to 15 days.

Equity Home Bias and Corporate Disclosure
Stefan Eichler
Journal of International Money and Finance,
No. 5,
2012
Abstract
I show that more comprehensive corporate disclosure reduces investors’ uncertainty about domestic companies’ payoffs at no cost, thereby decreasing investors’ equity home bias toward a country. Since investors should base their investment decisions on valid and easily interpretable company information only, more comprehensive disclosure will reduce the home bias only if domestic securities law is sufficiently stratified and domestic companies use international accounting standards. Using panel data for 38 countries from 2003 to 2008 I find that more comprehensive disclosure reduces investors’ home bias, though significantly only for countries that sufficiently enforce their securities law and implement international accounting standards.

Limited Investor Attention and the Mispricing of American Depositary Receipts
Stefan Eichler
Economics Letters,
No. 3,
2012
Abstract
I test whether more investor attention leads to a better exploitation of arbitrage opportunities and, in turn, to less mispricing of American Depositary Receipts (ADRs). Using data on 536 stocks I find that more investor attention significantly reduces ADR mispricing.

The Distorting Impact of Capital Controls
Makram El-Shagi
German Economic Review,
No. 1,
2012
Abstract
This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation.

Extreme Dependence with Asymmetric Thresholds: Evidence for the European Monetary Union
Stefan Eichler, R. Herrera
Journal of Banking and Finance,
No. 11,
2011
Abstract
Existing papers on extreme dependence use symmetrical thresholds to define simultaneous stock market booms or crashes such as the joint occurrence of the upper or lower one percent return quantile in both stock markets. We show that the probability of the joint occurrence of extreme stock returns may be higher for asymmetric thresholds than for symmetric thresholds. We propose a non-parametric measure of extreme dependence which allows capturing extreme events for different thresholds and can be used to compute different types of extreme dependence. We find that extreme dependence among the stock markets of ten initial EMU member countries, the United Kingdom, and the United States is largely asymmetrical in the pre-EMU period (1989–1998) and largely symmetrical in the EMU period (1999–2010). Our findings suggest that ignoring the possibility of asymmetric extreme dependence may lead to an underestimation of the probability of co-booms and co-crashes.

Stock Market Firm-Level Information and Real Economic Activity
Filippo di Mauro, Fabio Fornari, Dario Mannucci
ECB Working Paper,
No. 1366,
2011
Abstract
We provide evidence that changes in the equity price and volatility of individual firms (measures that approximate the definition of 'granular shock' given in Gabaix, 2010) are key to improve the predictability of aggregate business cycle fluctuations in a number of countries. Specifically, adding the return and the volatility of firm-level equity prices to aggregate financial information leads to a significant improvement in forecasting business cycle developments in four economic areas, at various horizons. Importantly, not only domestic firms but also foreign firms improve business cycle predictability for a given economic area. This is not immediately visible when one takes an unconditional standpoint (i.e. an average across the sample). However, conditioning on the business cycle position of the domestic economy, the relative importance of the two sets of firms - foreign and domestic - exhibits noticeable swings across time. Analogously, the sectoral classification of the firms that in a given month retain the highest predictive power for future IP changes also varies significantly over time as a function of the business cycle position of the domestic economy. Limited to the United States, predictive ability is found to be related to selected balance sheet items, suggesting that structural features differentiate the firms that can anticipate aggregate fluctuations from those that do not help to this aim. Beyond the purely forecasting application, this finding may enhance our understanding of the underlying origins of aggregate fluctuations. We also propose to use the cross sectional stock market information to macro-prudential aims through an economic Value at Risk.

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
