Thanks to robust domestic demand, the impact of the manufacturing sector on East Germany is less severe than in the west – Implications of the Autumn 2019 Joint Economic Forecast and official regional data for the eastern German economy
In its autumn report, the Joint Economic Forecast Project Group states that the German economy has cooled further in the current year. The manufacturing sector is the main reason for the economic weakness. This affects the economy in East Germany as well.

Service providers in Berlin give boost to East German economy – implications of the Joint Economic Forecast and of official data on the East German economy in 2018
In its spring report, the Joint Economic Forecast group states that the upturn in Germany came to an end in the second half of 2018, mainly because the manufacturing sector is weakening due to a slowing international economy and to problems in the automotive industry. Accordingly, in places such as Saxony (1.2%), Thuringia (0.5%), and Saxony-Anhalt (0.9%), where manufacturing plays a particularly important role, gross domestic product (GDP) grew less than in Germany as a whole (1.4%).

The Case for a European Rating Agency: Evidence from the Eurozone Sovereign Debt Crisis

Journal of International Financial Markets, Institutions and Money,
2019
Abstract
Politicians frequently voice that European bond issuers would benefit from the presence of a Europe-based rating agency. We take Fitch as a prototype for such an agency. With its ownership structure and a headquarter in London, Fitch is more European than Moody’s and S&P; during the Eurozone sovereign debt crisis, it also issued more favorable ratings. Fitch’s rating actions, however, were largely ignored by the bond market. Our results thus cast doubt on the benefits of a European credit rating agency.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Journal of Banking and Finance,
2018
Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a feedback loop leading into default as a transitory state for all but the very worst ratings. We use a bivariate semiparametric dynamic panel model to reproduce the joint dynamics of sovereign ratings and government bond yields. The individual equations resemble Pesaran-type cointegration models, which allow for valid interference regardless of whether the employed variables display unit-root behavior. To incorporate most of the empirical features previously documented (separately) in the literature, we allow for different long-run relationships in both equations, nonlinearities in the level effects of ratings, and asymmetric effects in changes of ratings and yields. Our finding of a single good equilibrium implies the slow convergence of ratings and yields toward this equilibrium. However, the persistence of ratings is sufficiently high that a rating shock can have substantial costs if it occurs at a highly speculative rating or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

Politicians share responsibility for the risk of their state defaulting
Investors assume higher risks of default when a country is politically unstable or governed by a party at the left or right end of the political spectrum. However, according to findings obtained by Stefan Eichler from the Halle Institute for Economic Research (IWH), the more democratic the country is and the more it is integrated into the global economy, the lower is the impact that such political factors have.

Why They Keep Missing: An Empirical Investigation of Rational Inattention of Rating Agencies
Gregor von Schweinitz, Makram El-Shagi
Abstract
Sovereign ratings have frequently failed to predict crises. However, the literature has focused on explaining rating levels rather than the timing of rating announcements. We fill this gap by explicitly differentiating between a decision to assess a country and the actual rating decision. Thereby, we account for rational inattention of rating agencies that exists due to costs of reassessment. Exploiting information of rating announcements, we show that (i) the proposed differentiation significantly improves estimation; (ii) rating agencies consider many nonfundamental factors in their reassessment decision; (iii) markets only react to ratings providing new information; (iv) developed countries get preferential treatment.

Worse ratings by U.S. rating agencies for European sovereigns no argument for European rating agency
A new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows that the major U.S. rating agencies rated European sovereigns significantly worse than Fitch, which is more “Europe oriented”. Although the findings in part support the claim of some European politicians during the recent debt crisis that there was an “anti-Europe” bias of the U.S. agencies, the study shows that a new European agency would not address this problem. The reason: Market participants would not listen to the new agency.

European versus Anglo-Saxon Credit View: Evidence from the Eurozone Sovereign Debt Crisis
Marc Altdörfer, Carlos A. De las Salas Vega, Andre Guettler, Gunter Löffler
Abstract
We analyse whether different levels of country ties to Europe among the rating agencies Moody’s, S&P, and Fitch affect the assignment of sovereign credit ratings, using the Eurozone sovereign debt crisis of 2009-2012 as a natural laboratory. We find that Fitch, the rating agency among the “Big Three” with significantly stronger ties to Europe compared to its two more US-tied peers, assigned on average more favourable ratings to Eurozone issuers during the crisis. However, Fitch’s better ratings for Eurozone issuers seem to be neglected by investors as they rather follow the rating actions of Moody’s and S&P. Our results thus doubt the often proposed need for an independent European credit rating agency.
