Abstract
East German manufacturers’ revenue productivity (value-added per worker) is some 8 (25) percent below West German levels, even three decades after German unification. Using firm-product-level data containing information on product quantities and prices, we analyse the role of product specialisation and reject the prominent ‚extended work bench hypothesis‘, stating a specialisation of Eastern firms in the intermediate input production as explanation for these sustained productivity differences. We decompose the East’s revenue productivity disadvantage into Eastern firms selling at lower prices and producing more physical output for given amounts of inputs within ten-digit product industries. This suggests that Eastern firms specialise vertically in simpler product varieties generating less consumer value but being manufactured with less or cheaper inputs. Vertical specialisation, however, does not explain the productivity gap as Eastern firms are physically less productive for given product prices, implying a genuine physical productivity disadvantage of Eastern compared to Western firms

Labor Market Power and the Distorting Effects of International Trade
Matthias Mertens
International Journal of Industrial Organization,
No. 102562,
2020
Abstract
This article examines how final product trade with China shapes and interacts with labor market imperfections that create market power in labor markets and prevent an efficient market outcome. I develop a framework for measuring such labor market power distortions in monetary terms and document large degrees of these distortions in Germany's manufacturing sector. Import competition only exerts labor market disciplining effects if firms, rather than employees, possess labor market power. Otherwise, increasing export demand and import competition both fortify existing distortions, which decreases labor market efficiency. This widens the gap between potential and realized output and thus diminishes classical gains from trade.

East Germany Three Decades After the Wall Came Down: What has Been Achieved and What Should Economic Policy Do?
Reint E. Gropp, Gerhard Heimpold
Wirtschaftsdienst,
forthcoming
Abstract
The persistent difference in productivity between East and West Germany not only results from the relative absence of large firms based in the East as many believe. Companies of all sizes exhibit an East-West productivity gap. The gap is larger in urban regions. Scarcity of skilled labour has emerged as the new barrier to business development. In order to boost productivity, economic policy should avoid additional subsidies that are conditional on creating jobs. Additionally, the potential of East German urban areas should be better explored. Mitigating the shortage in qualified workers requires in-migration of skilled labour from abroad, supported by an open mindset and environment.

Abstract
The economic situation in German establishments improved even further in 2017. The development of wages, however, reflects this economic growth only partly. Compared to 1997, the wage differential between large and small establishments increased considerably – with substantially lower wages paid in East Germany in general. The wage differential of about 19 percent between East and West Germany can to some extent be explained in a multivariate analysis (Blinder-Oaxaca decomposition) showing that the main cause for the wage gap is the productivity gap between East German and West German establishments; other structural heterogeneities like sector composition, industrial relations and size structure seem not to contribute to an explanation of this gap. The overall positive economic development in Germany is associated with a further growth in total employment and with increased labor market dynamics, especially regarding employee turnover. Turnover rates, however, are very heterogeneous among sectors, ranging from 23 percent in the accommodation and food service sector and less than five percent in public administration. Also the demand for skilled personnel continued to grow. Yet for the first time, not even two thirds of the posted job vacancies could be filled in 2017. With over fifty percent, this non-occupancy quota is particularly high in the construction industry. Also small and very small establishments face serious recruitment problems. The structure of formal occupational skill requirements did not change very much over recent years, but the increasing use of digital technologies changes everyday job requirements and may lead to a rising workload for employees. Looking at the personnel structure in the German economy, a growing share of atypical employment becomes apparent, especially in form of part-time jobs. The proportion of marginal employment remains relatively stable and is comparatively high in sectors with less specific knowledge requirements and strong cyclical and/or seasonal fluctuations like is the case in accommodation and food service sector or personal services sector. Since 2010, the proportion of establishments authorized to provide in-company vocational training has declined constantly and now accounts for 53 percent of the establishments in Germany. About one half of these establishments do actually train apprentices. The share of vacant apprenticeships further increased in 2017 to about one quarter of all apprenticeships offered, in East Germany even to more than one third. As in recent years, the share of establishments supporting further training of their employees remained stable at about fifty percent and the proportion of employees participating in training is still about one third. In East Germany these figures prove to be slightly higher.

Does Intermunicipal Cooperation Increase Efficiency? A Conditional Metafrontier Approach for the Hessian Wastewater Sector
F. Blaeschke, Peter Haug
Local Government Studies,
No. 1,
2018
Abstract
This paper analyses the relationship between intermunicipal cooperation and efficiency of public service provision. Organisational arrangements of public service production, including self-provision, joint provision or contracting, affect incentives and internal transaction costs. Hence, cooperation gains from scale effects need to be balanced against technical inefficiencies. We analyse relative efficiency of wastewater disposal for German municipalities. We employ a conditional analysis in conjunction with a metafrontier approach to calculate relative efficiency measures and technology gap ratios controlling for organisational arrangements and further environmental variables. Jointly providing municipalities and contractor municipalities exhibit lower technical efficiency than self-providing and contracting municipalities. As confirmed by previous research, scale effects from cooperation and contracting apply to small municipalities primarily.

Economic Transition in Unified Germany and Implications for Korea

H.-G. Jeong and G. Heimpold (eds.): Economic Transition in Unified Germany and Implications for Korea. Policy References 17-13. Sejong: Korea Institute for International Economic Policy,
2017
Abstract
The reunification of Germany, which marked the end of the Cold War in the 20th century, is regarded as one of the most exemplary cases of social integration in human history. Nearly three decades after the German reunification, the economic and social shocks that occurred at the beginning of the reunification process have largely been resolved. Moreover, the unified Germany has grown into one of the most advanced economies in the world.
The unification process that Germany underwent may not necessarily be the way that the Republic of Korea would choose. However, the economic and social exchanges between East and West Germany prior to unification, and the cooperation in a myriad of policies based on these exchanges, served as the crucial foundation for unification. The case of Germany will surely help us find a better way for the re-unification of the Korean Peninsula.
In this context, this is the first edition of a joint research which provides diverse insights on social and economic issues during the process of unification. It consists of nine chapters whose main topics include policies on macroeconomic stabilization, the privatization of state-owned enterprises in East Germany, labor policies and the migration of labor, integration of the social safety nets of the North and South, and securing finances for reunification. To start with, the first part covers macroeconomic stabilization measures, which include policies implemented by the federal government of Germany to overcome macroeconomic shocks directly after the reunification. There was a temporary setback in the economy at the initial phase of reunification as the investment per GDP went down and the level of fiscal debt escalated, reverting to its original trend prior to the reunification. While it appears the momentum for growth was compromised by reunification from the perspective of growth rate of real GDP, this state did not last long and benefits have outpaced the costs since 2000.
In the section which examines the privatization of state-owned enterprises in East Germany, an analysis was conducted on the modernization of industrial infrastructure of East German firms. There was a surge in investment in East German area at the beginning stages but this was focused on a specific group of firms. Most of the firms were privatized through unofficial channels, with a third of these conducted in a management buy-out (MBO) process that was highly effective. Further analysis of a firm called Jenoptik, which was successfully bailed out, is incorporated as to draw implications of its accomplishments.
In the section on migration, we examine how the gap between the unemployment rates in the West and East have narrowed as the population flow shifted from the West to East. Consequently, there was no significant deviation in terms of the Gross Regional Domestic Product (GRDP) per capita in each state of East Germany. However, as the labor market stabilized in East Germany and population flows have weakened, the deviation will become larger. Meanwhile, if we make a prediction about the movement of population between the North and the South, which show a remarkable difference in their economic circumstances, a radical reunification process such as Germany’s case would force 7% of the population of the North to move towards the South. Upon reunification, the estimated unemployment rate in North Korea would remain at least 30% for the time being. In order to reduce the initial unemployment rate, it is crucial to design a program that trains the unemployed and to build a system that predicts changes in labor demand.
It seems nearly impossible to apply the social safety nets of the South to the North, as there is a systemic difference in ideologies. Taking steps toward integration would be the most suitable option in the case of the Koreas. We propose to build a sound groundwork for stabilizing the interest rates and exchange rates, maintain stable fiscal policies, raise momentum for economic growth and make sure people understand the means required to financially support the North in order to reduce the gap between the two.
This book was jointly organized and edited by Dr. Hyung-gon Jeong of the Korea Institute for International Economic Policy (KIEP) and Dr. Gerhard Heimpold of the Halle Institute for Economic Research (IWH). We believe that this report, which examines numerous social and economic agendas that emerged during the reunification of Germany, will provide truly important reference for both Koreas. It is also our view that it will serve as a stepping-stone to establish policies in regard to South-North exchanges across numerous sectors prior to discussions of reunification. KIEP will continue to work with IWH and contribute its expertise to the establishment of grounds for unification policies.

Produktivitätsunterschiede zwischen West- und Ostdeutschland und mögliche Erklärungsfaktoren. Ergebnisse aus dem IAB-Betriebspanel 2016

Abstract
After several years of prosperity, the economic situation of German establishments improved further in 2016. Though the productivity in East German establishments converged slightly to the West German level, a significant productivity gap between both parts of Germany still remains. Differences in the economic structure can only explain a small part of this persistent gap: a Blinder-Oaxaca decomposition suggests that the different sector composition, lower exports and lower capital intensity of East German establishments explain only about one-fifth of the backlog. The observed positive economic development is associated with a further increase in firm profitability and total employment in the establishments in both parts of Germany. It is reflected also in a further increase in the demand for skilled personnel. Even though the majority of the demand could be met in 2016, one-third of all offered jobs remained vacant. As in the past, especially establishments in construction and business services as well as very small establishments, particularly in East Germany, faced considerable recruitment problems. The occupational skill requirements increased slightly over time. The proportion of jobs for skilled workers is on average higher in East German establishments than in West Germany, suggesting a higher formal qualification level of employees in East Germany. Looking at the personnel structure, a significant increase in the share of atypical employment, particularly part-time jobs and marginal employment, over the last years become visible. The participation of establishments in vocational training remains relatively stable: about half of the enterprises that are authorized to provide vocational training do actually train apprentices. However, the corresponding fraction in East Germany is significantly lower since the economic crisis. In contrast, the share of vacant apprenticeship positions there is much higher than in West German establishments, pointing to major problems in finding suitable applicants. The share of employees participating in further training is about one third for several years. As in the past workers in low-skilled occupations participate only about half as often in training as employees in qualified jobs.

How Can We Boost Competition in the Services Sector?
Oliver Holtemöller
Externer Herausgeberband, Nomos,
2017
Abstract
‘How Can We Boost Competition in the Services Sector?’ is a key question in the process of creating a more effi-cient economic environment in Germany. This book contains a collection of conference contributions on service sector reforms from members of academic institutions, ministries, the EU Commission and other organisations. The conference consisted of a keynote on the importance and implementation of structural reforms in Europe and two panels that dealt with the evaluation of past reforms in the services sector and the potential scope and effects of further reforms. Since the 1990s, productivity growth in Germany and other Member States of the European Union has been significantly lower than in the US. The development of productivity growth in the services sector is estimated to account for two thirds of this widening gap. The European Commission advocated reforms in the services sector in its country-specific recommendations for Germany. At a conference in Berlin in July 2016, experts from various fields presented and discussed studies on service sector reforms.

Aktuelle Trends: Ertragslage der ostdeutschen Betriebe verbessert sich stetig
Steffen Müller
Wirtschaft im Wandel,
No. 3,
2017
Abstract
Ostdeutschland weist auch mehr als 25 Jahre nach der deutschen Vereinigung eine um circa ein Viertel geringere Arbeitsproduktivität als Westdeutschland auf. Wesentlich geringer ist der Rückstand jedoch bei der Ertragslage. Vor elf Jahren machten etwa 70% der westdeutschen Betriebe und 65% der ostdeutschen Betriebe Gewinne. Nach einem kurzen Knick um die Wirtschafts- und Finanzkrise 2009 ist dieser Anteil kontinuierlich auf 80% im Westen und 76% im Osten angestiegen. Das bedeutet, dass sich beide Landesteile bei dieser Kennzahl seit geraumer Zeit mit recht geringem Abstand im Gleichschritt bewegen.
