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.

Reform of IMF Lending Facilities Increases Stability in Emerging Market Economies
J. John, Tobias Knedlik
Wirtschaft im Wandel,
No. 3,
2010
Abstract
Following the current international financial and economic crisis the IMF reformed its lending facilities. Two new instruments are of particular importance: the Flexible Credit Line (FCL) and the High Access Precautionary Arrangements (HAPA). The major innovation of the new facilities is that the traditional ex-post conditionality is replaced by an ex-ante qualification process. An ex-ante qualification process leads to a short-term availability of funds during the emergence of crises and avoids long negotiation processes during a crisis. Additionally, the FCL is high powered, amounting to 900 to 1000% of the quota. It can therefore be expected that the programs have preventive effects. In difference to previous attempts to implement precautionary credit lines, the FCL and HAPA successfully created demand. First empirical observations show, that a stigmatization, which could have been expected from experience, did not take place. Countries who qualified for the FCL did rather well during the current crisis and did not face shrinking confidence due to expected crises. To be more efficient, the new lending facilities should be complemented be an international regulatory framework, which limits moral-hazard-induced higher risk taking. Additionally more members should be encouraged to demand the new instruments to increase its systemic importance.

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.

Characteristics of Business Cycles: Have they Changed?
Oliver Holtemöller, J. Rahn, M. H. Stierle
IWH-Sonderhefte,
No. 5,
2009
Abstract
The most recent economic downturn has shown that economic activity nowadays is still prone to large fluctuations. Despite a long tradition of research, the understanding of such fluctuations, namely business cycles, is still far from comprehensive. Moreover, in a developing world with new technologies, faster communication systems, a higher integration of world markets and increasingly better-skilled people the nature of business cycles changes continuously and new insights can be drawn from recent experience.

Die wirtschaftliche Transformation in den neuen Ländern: Mehr als eine rein ökonomische Aufgabe
Ulrich Blum
Die Politische Meinung,
2009
Abstract
Often the rise from the ruins of socialism is only considered from an economic perspective. In fact we know that economic success relates to considerable extent to its cultural prerequisites. The article analyzes the present development of the New Lander within the perspective of pre-economic cultural imprints of East Germany. It shows for East Germany that beside the specific mixture of protestant work ethic and status seeking, which generated own “living worlds”, the different development of society, especially the middleclass basis and entrepreneurship are of special importance. In addition, the lost interest in unification by West Germany is an important factor that explains why West Germans had little interest to explain their own economic and social system. These conditions put economic performance in a critical perspective.

Deutsche Einheit – ein wirtschaftlicher Gewinn
Ulrich Blum
MUT – Zeitschrift für Kultur,
2009
Abstract
20 years after the fall of the wall the interest in the evaluation of the economic development of Germany after unification has increased. The article shows that from a Western German perspective, unification generated large gains because in an expending fail of economic development highly qualified personal from East Germany could be attracted and triggered growth in the West. This also generated a modernization of industry. The perspective on the Eastern side is more mixed. After a first transitory face, an ultra-modern industry has emerged, but gaps in the headquarter functions still exist. They can only be closed within a context of a new technology cycle. From the perspective of unified Germany, the high transfers of 1.3 trillion Euros in the last 20 years, dominantly used for stabilizing social security systems in the East, could mostly be faced out of unification-related additional economic performance in West Germany.

East German Exports: Remarkable Catch-up, but Still Lagging Behind
Götz Zeddies
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
German reunification entailed severe adjustment processes in East German export industries. With political and economic transition in Eastern Europe, at that time the main export market for East German producers, export demand initially collapsed in the early 1990s. Additionally, the introduction of the Deutschmark in Eastern Germany amounted to a massive revaluation, and international competitiveness of East German producers deteriorated. However, manufacturers in the New Federal States opened up new markets, especially in Western Europe and the Americas. As a consequence, after the downturn of construction activity and investment in the mid-1990s, international trade became the driving force of GDP-growth in Eastern Germany. Although since then, goods exports of the New Federal States grew twice as much as those of Western Germany, export ratio (goods exports as a percentage of GDP) only amounts to 22 per cent in Eastern Germany, compared to 42 per cent in the western part of the country. Even in comparison to Eastern European countries in transition, openness to trade of the New Federal States is still comparatively low. As an empirical analysis shows, this must be largely traced back to smaller firm sizes in the New Federal States as well as to the lower importance of manufacturing industries, which are traditionally more export-oriented. Moreover, East German manufacturers largely specialized on intermediate inputs, which are supplied to final assembly lines in Western Germany, but are not recorded as exports. Thereby, East German export performance is considerably underestimated.

The Manufacturing Sector in East Germany on a Path from De-industrialization to Re-industrialization: Are there Economically Sustainable Structures?
Gerhard Heimpold
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
The contribution comprises an analysis how the manufacturing sector in East Germany has developed in the post-transition period after 1990. A set of economic performance indicators is used. The analysis shows a considerable growth of gross value added and productivity. However, the growth of productivity occurred at the expense of employment. On average, in 2008, the East German manufacturing sector reached 4/5th of the productivity level of the West German level. As far as the endowment with growth determinants is concerned, the manufacturing industry in the New German Länder has undertaken considerable efforts to modernize its fixed capital stock. The endowment with human capital measured by the proportion of employees possessing a university degree is as high as in the western part of Germany. However, the investigation reveals a number of deficits, too. Data on Research and Development (R&D) expenditures and R&D staff in the manufacturing sector reveal, on average, lower R&D activities in the East German manufacturing sector. This is resulting from specific structures of the East German manufacturing sector: dominance of small firms, lack of large firms possessing headquarters and conducting own R&D. Complementary, the share of technology-driven industries is lower, and the proportion of labor intensive industries is larger in comparison with the West German manufacturing sector. In addition, an investigation of functional structures of employment reveals a proportion of employment in production functions which is above the West German average, whereas the opposite is the case with the proportion of employment in service functions. For further strengthening the East German manufacturing sector, structural change toward technology-intensive and human capital-intensive economic activities has to be continued.
