N2  - This dissertation explores the determinants for sustainable and socially optimalgrowth in a city. Two general equilibrium models establish the base for this evaluation, each adding its puzzle piece to the urban sustainability discourse and examining the role of non-market-based and market-based policies for balanced growth and welfare improvements in different theory settings. Sustainable urban growth either calls for policy actions or a green energy transition.  Further, R&D market failures can pose severe challenges to the sustainability of urban growth and the social optimality of decentralized allocation decisions. Still, a careful (holistic) combination of policy instruments can achieve sustainable growth and even be first best.
N2  - Diese Dissertation untersucht die Determinanten für ein nachhaltiges und sozial optimales Wachstum in den Städten. Zwei endogene Wachstumsmodelle untersuchen hierzu die Rolle von nichtmarktbasierten und marktbasierten Politikeingriffen. Jedes Modell fügt dabei dem städtischen Nachhaltigkeitsdiskurs sein eigenes Puzzleteil hinzu. Nachhaltiges städtisches Wachstum erfordert entweder politische Maßnahmen oder eine grüne Energiewende. Darüber hinaus können Verzerrungen im Forschungsmarkt ernsthafte Herausforderungen für die Nachhaltigkeit des städtischen Wachstums und für die soziale Optimalität dezentralisierter Allokationsentscheidungen darstellen. Dennoch kann eine sorgfältige (ganzheitliche) Kombination von Politikinstrumenten Erfolg haben und zu einem sozial optimalen Resultat führen.

N2  - Economists are worried that the lack of property rights to natural capital goods jeopardizes the sustainability of the economic growth miracle that has existed since industrialization. This article questions their position. A vertical innovation model with a portfolio of technologies for abatement, adaptation, and general (Harrod-neutral) technology reveals that environmental damage spillovers have a comparable effect on research profits as technology spillovers so that the social costs of depleting public natural capital are internalized. As long as there is free access to information and technology, growth is sustainable and the allocation of research efforts among alternative technologies is socially optimal. While there still is a need to address externalities from monopolistic research markets, no environmental policy is necessary. These results suggest that environmental externalities may originate in restricted access to information and technology, demonstrating that (i) information has a similar effect as an environmental tax and (ii) knowledge and technology transfers have an impact comparable to that of subsidies for research in green technology.
