Inflation Expectations: Does the Market Beat Professional Forecasts?

No. 16,

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.

Industry Concentration and Regional Innovative Performance – Empirical Evidence for Eastern Germany
Christoph Hornych, Michael Schwartz
IWH Discussion Papers,
No. 8,
2009
Abstract
Regarding technological innovativeness, the transformed economy of the former German Democratic Republic (GDR) clearly lags behind the Western part of the country. To face this weakness, a broad mixture of policy measures was carried out in recent years. Particular attention is drawn to the development of industry concentrations and economic ‘clusters’. However, little is known about the effectiveness of these policy measures regarding how industry concentrations in fact promote innovative performance in Eastern Germany. The present study tries to fill this gap by analyzing the relationship between industry concentration in Eastern Germany and regional innovative performance. Our empirical analysis is based upon the number of patent applications of 22 manufacturing industries in 22 Eastern German planning regions. The estimated regression models indicate an inverted U-shaped relationship between the degree of industry concentration and innovative performance. An exceedingly high degree of industry concentration in one region hampers regional innovative output. We discuss policy implications of our findings and give recommendations for future refinement of ‘cluster’-supporting policy schemes in Eastern Germany.

The Euro and the Competitiveness of European Firms

No. 57,

Abstract
Much attention has been paid to the impact of a single currency on actual trade volumes. Lower trade costs, however, matter over and beyond their effects on trade flows: as less productive firms are forced out of business by the tougher competitive conditions of international markets, economic integration fosters lower prices and higher average productivity. We assess the quantitative relevance of these effects calibrating a general equilibrium model using country, sector and firm-level empirical observations. The euro turns out to have increased the overall competitiveness of Eurozone firms, and the effects differ along interesting dimensions: they tend to be stronger for countries which are smaller or with better access to foreign markets, and for firms which specialize in sectors where international competition is fiercer and barriers to entry lower.— Gianmarco I.P.

Metformin-Therapie bei PCO-Syndrom - Positive Vierjahresbilanz des oralen Antidiabetikums
D. Albrecht, P. Kaltwasser, E. Rosenkranz, Dirk Trocka
MedReview,
2007
Abstract
Das Polyzystische Ovarialsyndrom (PCOS) ist mit einer Krankheitshäufigkeit von 4–12 % die häufigste endokrine Erkrankung der Frau im reproduktiven Alter. Neben dem unerfüllten Kinderwunsch stellt es ein hohes Risiko für metabolische (stoffwechselbedingte) und kardiovaskuläre (Herz und Blutgefäße betreffende) Erkrankungen dar. Die Studie stellt die ersten Ergebnisse der Behandlung des PCOS mit dem oralen Antidiabetikum Metformin in einer Vierjahres-Analyse dar und versucht Kriterien für den Einsatz des Arzneistoffes zu definieren.

Inflation and relative price variability in the euro area: evidence from a panel threshold model
Dieter Nautz, Juliane Scharff
Bundesbank Discussion Paper, No. 14/2006,
2006
Abstract
In recent macroeconomic theory, relative price variability (RPV) generates the
central distortions of inflation. This paper provides first evidence on the empirical
relation between inflation and RPV in the euro area focusing on threshold effects
of inflation. We find that expected inflation significantly increases RPV if inflation
is either very low (below -1.38% p.a.) or very high (above 5.94% p.a.). In the
intermediate regime, however, expected inflation has no distorting effects which
supports price stability as an outcome of optimal monetary policy.

Can EU Policy Intervention Help Productivity Catch-Up?
Johannes Stephan, P. Holmes, J. Lopez-Gonzales, C. Stolberg
Closing the EU East-West Productivity Gap - Foreign direct Investment, Competitiveness, and Public Policy,
2006
Abstract
"A product of the Framework V research project, this book addresses one of the key problems facing the EU today: Why is the ‘new’ EU so much poorer than the ‘old’, and how will EU enlargement help to solve the problem? Focusing on the productivity problems underlying the East-West gap, it looks in particular at the role that foreign investment and R&D can play in closing it. Against that background, the book assesses what role proactive development policy might play in attacking the roots of low social productivity. Concluding that there will be a clear-cut process of convergence between East and West, albeit an incomplete one, it finishes with an assessment of the patterns of competitiveness, East and West, that are likely to emerge from this process of incomplete convergence."
