Bottom-up or Direct? Forecasting German GDP in a Data-rich Environment
Katja Drechsel, Rolf Scheufele
Abstract
This paper presents a method to conduct early estimates of GDP growth in Germany. We employ MIDAS regressions to circumvent the mixed frequency problem and use pooling techniques to summarize efficiently the information content of the various indicators. More specifically, we investigate whether it is better to disaggregate GDP (either via total value added of each sector or by the expenditure side) or whether a direct approach is more appropriate when it comes to forecasting GDP growth. Our approach combines a large set of monthly and quarterly coincident and leading indicators and takes into account the respective publication delay.

Foreign Bank Entry, Credit Allocation and Lending Rates in Emerging Markets: Empirical Evidence from Poland
Hans Degryse, Olena Havrylchyk, Emilia Jurzyk, Sylwester Kozak
Journal of Banking and Finance,
No. 11,
2012
Abstract
Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.

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.

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.

Stale Information, Shocks, and Volatility
Reint E. Gropp, A. Kadareja
Journal of Money, Credit and Banking,
No. 6,
2012
Abstract
We propose a new approach to measuring the effect of unobservable private information on volatility. Using intraday data, we estimate the effect of a well-identified shock on the volatility of stock returns of European banks as a function of the quality of public information available about the banks. We hypothesize that as publicly available information becomes stale, volatility effects and its persistence increase, as private information of investors becomes more important. We find strong support for this idea in the data. We further show that stock volatility is higher just before important announcements if information is stale.

Does Central Bank Staff Beat Private Forecasters?
Makram El-Shagi, Sebastian Giesen, A. Jung
IWH Discussion Papers,
No. 5,
2012
Abstract
In the tradition of Romer and Romer (2000), this paper compares staff forecasts of the Federal Reserve (Fed) and the European Central Bank (ECB) for inflation and output with corresponding private forecasts. Standard tests show that the Fed and less so the ECB have a considerable information advantage about inflation and output. Using novel tests for conditional predictive ability and forecast stability for the US, we identify the driving forces of the narrowing of the information advantage of Greenbook forecasts coinciding with the Great Moderation.

Credit Allocation and Value Creation of Banks: The Impact of Relationship Banking in Normal and Crisis-times
Hans Degryse, Steven Ongena
Revue d'économie financière,
No. 106,
2012
Abstract
In this paper we review the literature on credit allocation and value creation of banks. We focus on relationship banking that occurs when a bank and a borrower engage into multiple interactions and when both parties invest in obtaining some counterparty specific information. We summarize how relationship banking generates costs and benefits for both firms and banks, but argue that on average it generates value for both of them. The impact however hinges substantially on whether we are in normal times versus crisis times. We further discuss how credit allocation as measured by industry specialization impacts firms and banks. At last we review the recent literature on securitization and relationship banking to study how securitization impacts the effects of relationship banking.

Predicting Financial Crises: The (Statistical) Significance of the Signals Approach
Makram El-Shagi, Tobias Knedlik, Gregor von Schweinitz
Abstract
The signals approach as an early warning system has been fairly successful in detecting crises, but it has so far failed to gain popularity in the scientific community because it does not distinguish between randomly achieved in-sample fit and true predictive power. To overcome this obstacle, we test the null hypothesis of no correlation between indicators and crisis probability in three applications of the signals approach to different crisis types. To that end, we propose bootstraps specifically tailored to the characteristics of the respective datasets. We find (1) that previous applications of the signals approach yield economically meaningful and statistically significant results and (2) that composite
indicators aggregating information contained in individual indicators add value to the signals approach, even where most individual indicators are not statistically significant on their own.

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.

Clusterpolitiken in Bayern und Thüringen: Praxis eilt der Theorie voraus
In einer Vergleichsstudie hat das Institut für Wirtschaftsforschung Halle (IWH) anhand veröffentlichter Dokumente die Clusterpolitiken in den Ländern Bayern und Thüringen analysiert. Ziel dieser Politiken ist die Stärkung der Innovationskraft. Es fehlt jedoch eine explizite Begründung für die staatliche Unterstützung von Clustern im Sinne von Marktversagen, die darlegt, weshalb der Markt allein (aufgrund von externen Effekten, Informationsasymmetrien oder Koordinierungsmängeln) ein Zuwenig an Clusterbildung erzeugt. Offen bleibt daher, ob die praktizierte Clusterpolitik tatsächlich ursachenadäquat ist. In Thüringen wird Clusterpolitik mit der Kleinteiligkeit der Unternehmensstrukturen motiviert, was eher indirekt auf Informations- und Koordinierungsprobleme schließen lässt.
