Evaluating the German (New Keynesian) Phillips Curve

Abstract
This paper evaluates the New Keynesian Phillips curve (NKPC) and its hybrid variant within a limited information framework for Germany. The main interest resides in the average frequency of price re-optimization by firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method based on the Anderson–Rubin statistic. We find that the German Phillips curve is purely forward-looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every 2–3 quarters. These estimates seem plausible from an economic point of view. But the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity, where firms never re-optimize prices. This analysis also offers some explanation as to why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way in which orthogonality conditions are formulated. Further, model mis-specifications may be left undetected by conventional J tests. This analysis points out the need for identification robust methods to get reliable estimates for the NKPC.

A First Look on the New Halle Economic Projection Model
Sebastian Giesen, Oliver Holtemöller, Juliane Scharff, Rolf Scheufele
Abstract
In this paper we develop a small open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model – the Halle Economic Projection Model (HEPM) – is closely related to studies recently published by the International
Monetary Fund (global projection model). Our main contribution is that we model the Euro area countries separately. In this version we consider Germany and France, which represent together about 50 percent of Euro area GDP. The model allows for country specific heterogeneity in the sense that we capture different adjustment patterns to economic shocks. The model is estimated using Bayesian techniques. Out-of-sample and pseudo out-of-sample forecasts are presented.

Concerning the development of the debt level of the New Länder since the German unification
Sabine Freye
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 2 -
2010
Abstract
During the 1990s, public indebtedness rose remarkably in all German political subdivisions. This development was particularly strong in the New Länder. At the beginning of the 1990s, they had low indebtedness rates. Today, 20 years later, the debt level of some New Länder lies over the average value of all Federal states. The background of this development is complex and depends also on the individual situation of each state. Generally, the rise of the debt level of the New Länder can be attributed to the 1990s’ estimation of a fast adjustment of the New Länder’s economic and financial power to that of the old Federal states. From today's point of view, this estimation was too optimistic. Furthermore, the New Länder have been affected differently by the transformation-conditioned structural change and the therefore arising difficulties with the necessary adjustment to the market.
In Saxony-Anhalt, which is characterised by the highest debt level of the New Länder, the collapse of the basic industry has led to high regional unemployment and to a substantial migration of the population. Still Saxony-Anhalt has countrywide the largest negative migration balance.
Regardless of these state-specific characteristics of the transformation process, there is a gradual change in the attitude towards existing debts and their handling, starting around the year 2000. So, the interest in budget consolidation increases constantly. This development was supported by the economic boom of the years 2006 and 2007. At present, the economic crisis puts the consolidation efforts of the states to the test.

Das Problem der Finanzierung eines bedingungslosen Grundeinkommens
Ingmar Kumpmann
Franzmann, Manuel (Hrsg.), Bedingungsloses Grundeinkommen als Antwort auf die Krise der Arbeitsgesellschaft,
2010
Abstract
For an investigation of the financial feasibility of an unconditional basic income it is important to differentiate analytically between the introduction of a basic income itself and accompanying reform proposals in order to avoid the confusion of financial effects of different possible projects. The crucial point for the question of financing is the effects an unconditional basic income has on market production. These effects are not sufficiently investigated yet. But in any case it is very hard to estimate them. Thus it is recommendable to introduce the basic income in several steps in order to gather experiences about the economic effects. In doing so one should not start with a low basic income for all people but rather with a sufficiently high basic income for certain target groups.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model
Marco Sunder
IWH Discussion Papers,
No. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

Innovation and Skills from a Sectoral Perspective: A Linked Employer-Employee Analysis
Lutz Schneider, Jutta Günther, Bianca Brandenburg
Economics of Innovation and New Technology,
2010
Abstract
Science and engineering skills as well as management and leadership skills are often referred to as sources of innovative activities within companies. Broken down into sectoral innovation patterns, this article examines the role of formal education, actual occupation and work experience in the innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain information about corporate innovation activities and the qualification of employees in terms of formal education, actual professional status and work experience. We find clear differences in the human capital endowment between sectors according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in above average product innovation (specialized suppliers and science-based industries). However, according to our estimation results, across as well as within these sectors a large share of highly skilled employees does not substantially increase the probability of a firm being innovative.

Do All Countries Grow Alike?
Claire Economidou, J. W. B. Bos, Michael Koetter, James W. Kolari
Journal of Development Economics,
No. 1,
2010
Abstract
This paper investigates the driving forces of output change in 77 countries during the period 1970–2000. A flexible modeling strategy is adopted that accounts for (i) the inefficient use of resources, and (ii) different production technologies across countries. The proposed model can identify technical, efficiency, and input change for each of three endogenously determined regimes. Membership in these regimes is estimated, rather than determined ex ante. This framework enables explorations into the determinants of output growth and convergence issues in each regime.

Deriving the Term Structure of Banking Crisis Risk with a Compound Option Approach: The Case of Kazakhstan
Stefan Eichler, Alexander Karmann, Dominik Maltritz
Discussion paper, Series 2: Banking and financial studies, No. 01/2010,
No. 1,
2010
Abstract
We use a compound option-based structural credit risk model to infer a term structure of banking crisis risk from market data on bank stocks in daily frequency. Considering debt service payments with different maturities this term structure assigns a separate estimator for short- and long-term default risk to each maturity. Applying the Duan (1994) maximum likelihood approach, we find for Kazakhstan that the overall crisis probability was mainly driven by short-term risk, which increased from 25% in March 2007 to 80% in December 2008. Concurrently, the long-term default risk increased from 20% to only 25% during the same period.

Industry Concentration and Regional Innovative Performance – Empirical Evidence for Eastern Germany
Christoph Hornych, Michael Schwartz
Post-Communist Economies,
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 analysing 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 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.
