Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.

Abstract
Der Artikel untersucht mit Hilfe eines gesamtwirtschaftlichen Modells, welche Auswirkungen bei einer Kürzung von Transferleistungen für die neuen Länder zu erwarten sind. Dabei wird festgestellt, dass der Konvergenzprozess nur vorübergehend beeinträchtigt wird, mittelfristig aber keine negativen Auswirkungen für Ostdeutschland eintreten werden.

Abstract
Auf der Basis nachfragebezogener Simulationen mit dem makroökonomischen Modell des IWH wurden die Auswirkungen der Kürzung von Transferleistungen für die neuen Länder nach dem Auslaufen des Solidarpaktes im Jahr 2004 ermittelt. Hauptergebnis dieser Berechnungen ist, dass der kürzungsbedingte Nachfrageausfall für viele Jahre erhebliche Einbußen bei Produktion und Beschäftigung nach sich zöge. Die Simulation der angebotsseitigen Wirkungen zeigt, dass sowohl vom Ausbau der Infrastruktur als auch der Investitionsförderung erhebliche Wachstumsimpulse ausgehen.
