Grüne Transformation und Schuldenbremse: Implikationen zusätzlicher Investitionen für öffentliche Finanzen und privaten Konsum

Andrej Drygalla Katja Heinisch Oliver Holtemöller Axel Lindner Alessandro Sardone Christoph Schult Birgit Schultz Götz Zeddies

in: Konjunktur aktuell, Nr. 4, 2023

Abstract

Das deutsche Klimaschutzgesetz sieht unter anderem vor, dass die Treibhausgas-Emissionen in Deutschland bis zum Jahr 2030 um 65% gegenüber dem Jahr 1990 verringert werden. Die damit einhergehende Transformation der Wirtschaft hat weitreichende Konsequenzen für die gesamtwirtschaftliche Entwicklung und die öffentlichen Finanzen. Alles in allem erfordert der Ausbau erneuerbarer Energien für die Klimaschutzziele jährliche Investitionen in der Größenordnung von 2,5% in Relation zum Bruttoinlandsprodukt. Mithilfe eines makroökonomischen Modells kann gezeigt werden, mit welchen gesamtwirtschaftlichen Entwicklungen zu rechnen ist, wenn die Klimaschutzziele eingehalten werden.

Entwicklung der öffentlichen Gesundheitsausgaben

Götz Zeddies

in: Wirtschaftsdienst, Nr. 6, 2023

Abstract

Die sozialen Sicherungssysteme in Deutschland basieren auf dem Umlageverfahren, bei dem die Ausgaben der Sozialversicherungen in der laufenden Periode durch Einnahmen aus Beiträgen, die auf die Einkommen der abhängig Beschäftigten erhoben werden, gedeckt werden. Vor dem Hintergrund des demografischen Wandels, der in den kommenden Jahren immer stärker zum Tragen kommen wird, wird häufig die Nachhaltigkeit der umlagefinanzierten sozialen Sicherungssysteme hinterfragt, weil sich das Verhältnis von Beitragszahlern und Leistungsempfängern ändern wird. Dies dürfte sich zwar vor allem bei der gesetzlichen Rentenversicherung auswirken, aber auch bei der gesetzlichen Kranken- und der Pflegeversicherung.

Aktuelle Trends: Staatsverbrauch wieder zurück auf Vor-Covid-Trend

Oliver Holtemöller Götz Zeddies

in: Wirtschaft im Wandel, Nr. 2, 2023

Abstract

Der vierteljährliche Staatsverbrauch in Abgrenzung der Volkswirtschaftlichen Gesamtrechnungen ist im ersten Quartal 2023 wieder annähernd zurück auf den Vor-Covid-Trend gefallen. Mit dem Ausbruch der Corona-Pandemie im Frühjahr 2020 hatte der Staatsverbrauch deutlich zugenommen, weil dort zahlreiche Maßnahmen verbucht wurden, die der Staat zur Bewältigung der Pandemie ergriffen hat, etwa der Kauf von Schutzausrüstung, Corona-Tests, medizinische Behandlungen oder finanzielle Zuwendungen an Krankenhäuser.

Zu den rentenpolitischen Plänen im Koalitionsvertrag 2018 von CDU, CSU und SPD: Konsequenzen, Finanzierungsoptionen und Reformbedarf

Oliver Holtemöller Christoph Schult Götz Zeddies

in: Zeitschrift für Wirtschaftspolitik, Nr. 3, 2018

Abstract

In the coalition agreement from February 7, 2018, the new German federal government drafts its public pension policy, which has to be evaluated against the background of demographic dynamics in Germany. In this paper, the consequences of public pensions related policy measures for the German public pension insurance are illustrated using a simulation model. In the long run, the intended extensions of benefits would lead to an increase in the contribution rate to the German public pension insurance of about two and a half percentage points. Referring to pension systems of other countries, we discuss measures in order to limit this increase in the contribution rate.

On the Distribution of Refugees in the EU

Oliver Holtemöller Axel Lindner Andreas Schmalzbauer Götz Zeddies

in: Intereconomics, Nr. 4, 2016

Abstract

The current situation regarding the migration of refugees can only be handled efficiently through closer international cooperation in the field of asylum policy. From an economic point of view, it would be reasonable to distribute incoming refugees among all EU countries according to a distribution key that reflects differences in the costs of integration in the individual countries. An efficient distribution would even out the marginal costs of integrating refugees. In order to reach a political agreement, the key for distributing refugees should be complemented by compensation payments that distribute the costs of integration among countries. The key for distributing refugees presented by the EU Commission takes account of appropriate factors in principle, but it is unclear in terms of detail. The compensation payments for countries that should take relatively high numbers of refugees for cost efficiency reasons should be financed by reallocating resources within the EU budget.

Skill Content of Intra-european Trade Flows

Götz Zeddies

in: European Journal of Comparative Economics, Nr. 1, 2013

Abstract

In recent decades, the international division of labor has expanded rapidly in the wake of European integration. In this context, especially Western European high-wage countries should have specialized on (human-)capital intensively manufactured goods and should have increasingly sourced labor-intensively manufactured goods, especially parts and components, from Eastern European low wage countries. Since this should be beneficial for the high-skilled and harmful to the lower-qualified workforce in high-wage countries, the opening up of Eastern Europe is often considered as a vital reason for increasing unemployment of the lower-qualified in Western Europe. This paper addresses this issue by analyzing the skill content of Western European countries’ bilateral trade using input-output techniques in order to evaluate possible effects of international trade on labor demand. Thereby, differences in factor inputs and production technologies have been considered, allowing for vertical product differentiation. In this case, skill content of bilateral exports and imports partially differs substantially, especially in bilateral trade between Western and Eastern European countries. According to the results, East-West trade should be harmful particularly to the medium-skilled in Western European countries.

Bracket Creeps: Bane or Boon for the Stability of Numerical Budget Rules?

Martin Altemeyer-Bartscher Götz Zeddies

in: IWH Discussion Papers, Nr. 29, 2016

Abstract

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.

Corporate Taxation and Firm Location in Germany

Götz Zeddies

in: IWH Discussion Papers, Nr. 2, 2015

Abstract

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.

Determinants of International Fragmentation of Production in the European Union

Götz Zeddies

in: IWH Discussion Papers, Nr. 15, 2007

Abstract

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.
