Germany’s economy is so bad even sausage factories are closingIWHThe Economist, January 15, 2026
Im Koalitionsvertrag von CDU, CSU und SPD vom 7. Februar 2018 formuliert die neue Bundesregierung ihre rentenpolitischen Ziele. Diese sind vor dem Hintergrund der Bevölkerungsdynamik in Deutschland zu sehen. Ab dem Jahr 2020 wird sich die Altersstruktur der deutschen Bevölkerung deutlich verändern. In diesem Beitrag werden Simulationsrechnungen zu den Konsequenzen der rentenpolitischen Maßnahmen aus dem Koalitionsvertrag für die Finanzierung der gesetzlichen Rentenversicherung mit Hilfe eines Simulationsmodells dargestellt. Die im Koalitionsvertrag vorgesehenen Leistungsausweitungen verursachen langfristig Kosten in Höhe von etwa 2½ Prozentpunkten beim Beitragssatz zur gesetzlichen Rentenversicherung. Es werden ferner Maßnahmen – auch im Vergleich zu den Rentensystemen anderer Länder – diskutiert, mit denen der Anstieg des Beitragssatzes begrenzt werden könnte.
As taxpayers typically pay low attention to a small inflation-induced bracket creep of the income tax, policy-makers tend to postpone its correction into the future. However, the fiscal illusion fades away and political pressure for a tax relief arises since after some years the cumulative increase of the average tax rate exceeds a critical threshold. Using Germany as an example, this paper shows that bracket creeps can provoke revenue cycles in public budgets hindering governments’ compliance with the numerical budget rules. An indexation of the tax tariff could prevent such fluctuations and thus provides a favourable framework for the debt rule.
German Fiscal Federalism is characterized by a high degree of fiscal equalization which lowers the efficiency of local tax administration. Currently, a reform of the fiscal equalization scheme is on the political agenda. One option is to grant federal states the right to raise surtaxes on statutory tax rates set by the central government in order to reduce the equalization rate. In such an environment, especially those federal states with lower economic performance would have to raise comparatively high surtaxes. With capital mobility, this could further lower economic performance and thus tax revenues. Although statutory tax rates are so far identical across German federal states, corporate tax burden differs for several reasons. This paper tries to identify the impact of such differences on firm location. As can be shown, effective corporate taxation did seemingly not have a significant impact on firm location across German federal states.
In recent decades, the international division of labor expanded rapidly in course of globalization. In this context, highly developed countries specialized on (human) capital intensively manufactured goods and increasingly sourced parts and components from lowwage countries. Since this should be beneficial for the high-skilled and harmful for the lower qualified workforce, especially the opening up of Eastern Europe and the international integration of newly industrializing Asian economies are considered as main reasons for increasing unemployment of the lower qualified in high-wage countries. The present paper addresses this issue for selected Western European countries by analyzing factor content of trade, which allows inferring on factor demand patterns resulting from international trade. This is not only done for countries’ total external trade, but also for bilateral trade flows, using input-output analyses. Thereby, differences in factor inputs and production technologies are considered, allowing for product differentiation. According to the results, factor content of bilateral trade flows between Western European high-wage countries does hardly differ. However, the results are different for East-West trade, since exports from Western to Eastern Europe are distinctly more human capital intensively manufactured than imports of Western European high-wage countries from Eastern Europe.
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.
During the last decades, international trade flows especially of the industrialized countries allegedly became more and more intra-industry. At the same time, employment perspectives particularly of the low-skilled by tendency deteriorated in these countries. This phenomenon is often traced back to the fact that intra-industry trade, which should theoretically involve low labor market adjustment, became increasingly vertical in nature and might thus entail labor market disruptions. Against this background, the present paper investigates the relationship between international trade patterns and selected labor market indicators in European countries, with a focus on vertical intra-industry trade. As the results show, neither inter- nor vertical intra-industry trade do have a verifiable effect on wage spread in EU member states. As far as structural unemployment is concerned, the latter increases only with the degree of countries’ specialization on capi-tal intensively manufactured products in inter-industry trade relations. Only for unemployment of the less-skilled, a slightly significant impact of superior vertical intra-industry trade seems to exist. However, the link between unemployment of the lower qualified and inter-industry specialization on labor intensive goods as well as parts and components imports is considerably higher.
The last decades were characterized by large increases in world trade, not only in absolute terms, but also in relation to world GDP. This was in large parts caused by increasing exchanges of parts and components between countries as a consequence of international fragmentation of production. Apparently, greater competition especially from the Newly Industrializing and Post-Communist Economies prompted firms in ‘high-wage’ countries to exploit international factor price differences in order to increase their international competitiveness. However, theory predicts that, beside factor price differences, vertical disintegration of production should be driven by a multitude of additional factors. Against this background, the present paper reveals empirical evidence on parts and components trade as an indicator for international fragmentation of production in the European Union. On the basis of a panel data approach, the main explanatory factors for international fragmentation of production are determined. The results show that, although their influence can not be neglected, factor price differences are only one out of many causes for shifting production to or sourcing components from foreign countries.
