The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?

Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
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

Does Low-pay Persist across Different Regimes? Evidence from the German Unification
André Diegmann, Nicole Gürtzgen
Economics of Transition and Institutional Change,
Nr. 3,
2020
Abstract
Using German administrative data, we study across-regime low-pay persistence in the context of an economic transformation process. We first show that individuals' initial allocation to the post-unification low-wage sector was close to random in terms of market-regime unobservables. Consistent with a weak connection between individuals' true productivity and their pre-unification low-wage status, the extent of across-regime state dependence is found to be small and appears to vanish over time. For males, across-regime state dependence is most pronounced among the medium- and high-skilled, suggesting the depreciation of human capital as an explanation.

Economic Development after German Unification and Implications for Korea

Abstract
The situation on the Korean Peninsula entered a new phase following the 2018 Winter Olympics, further evolving through the April 27 inter-Korean summit and June 12 Singapore summit between the U.S. and North Korea. Expectations are high for new exchanges and cooperation that would potentially lead to peace and prosperity on the Korean Peninsula. This would be a great chance to depart from hostility that has lasted over decades. However, it is expected to take some time until economic cooperation between the two Koreas resumes, as the negotiations for denuclearization still remain unresolved.

Innovation Cooperation in East and West Germany: A Study on the Regional and Technological Impact

Abstract
In this paper, we investigate the impact of regional and technological innovation systems on innovation cooperation. We develop an indicator applicable to regions, which demonstrates the relative regional impact on innovation cooperation. Applying this method to German patent data, we find that regional differences in the degree of innovation cooperation do not only depend on the technology structure of a region but also on specific regional effects. High-tech oriented regions, whether east or west, are not automatically highly cooperative regions. East German regions have experienced a dynamic development of innovation cooperation since re-unification in 1990. Their cooperation intensity remains higher than in West German regions.

German Unification: Macroeconomic Consequences for the Country

2017
Abstract
This paper shows basic macroeconomic consequences of the German unification for the country in time series spanning from 20 years before the event until 25 years thereafter. Essential findings can well be explained by elementary economic theory. Moreover, it is shown that the German economy had been off steady state already before unification in important aspects. In particular, a steep increase in the current account balance during the 1980s suggests that globalization strongly affected the German economy at that time. While unification stopped the trend to an ever more open economy and to a rising trade surplus for about 10 years, the fall of the iron curtain eventually even increased this trend in the long run.
