This paper investigates the redistributive effects of taxation on occupational choice and growth. We discuss a twoñsector economy in the spirit of Romer (1990). Agents engage in one of two alternative occupations: either selfñemployment in an intermediate goods sector characterized by monopolistic competition, or employment as an ordinary worker in this sector. Entrepreneurial pro_ts are stochastic. The occupational choice under risk endogenizes the number of _rms in the intermediate goods industry. While the presence of entrepreneurial risk results in a suboptimally low number of _rms and depresses growth, nonñlinear tax schemes are partly capable of compensating the negative by effects by ex post providing a social insurance.
Credit Constraints, Idiosyncratic Risks, and Wealth Distribution in a Heterogeneous Agent Model
(2007)
This paper examines the effects of credit market imperfections and idiosyncratic risks on occupational choice, capital accumulation, as well as on the income and wealth distribution in a two sector heterogeneous agent general equilibrium model. Workers and firm owners are subject to idiosyncratic shocks. Entrepreneurship is the riskier occupation. Compared to an economy with perfect capital markets, we find for the case of serially correlated shocks that more individuals choose the entrepreneurial profession in the presence of credit constraints, and that the fluctuation between occupations increases too. Workers and entrepreneurs with high individual productivity tend to remain in their present occupation, whereas low productivity individuals are more likely to switch between professions. Interestingly, these results reverse if we assume iid shocks, thus indicating that the nature of the underlying shocks plays an important role for the general equilibrium effects. In general, the likelihood of entrepreneurship increases with individual wealth.
This paper discusses the emergence of endogenous redistributive cycles in a stochastic growth model with incomplete asset markets and heterogeneous agents, where agents vote on the degree of progressivity in the taxñtransferñscheme. The model draws from BÈnabou (1996) and ties the bias in the distribution of political power to the degree of inequality in the society, thereby triggering redistributive cycles which then give rise to a nonlinear, cyclical pattern of savings rates, growth and inequality over time.
An der Universität Lüneburg veranstaltet die Professur Öffentliches Recht, inbes. Energie- und Umweltrecht in Kooperation mit der Professur für Bank- und Finanzwirtschaft am 13.10.2006 ein Symposium zum Thema „ Biogasanlagen – Recht und Finanzierung“. Die drei Themenblöcke gliederten sich in „Rechtsfragen“, „Finanzierung und Steuern“ sowie „Übergreifende Fragen“ und wurden von PD DR. Joachim Sanden, Prof. Dr. Heinrich Degenhart und Prof. Dr. Dr. h.c., (GTU Tiflis) Thomas Schomerus moderiert.
Mit der Richtlinie 2004/35/EG des Europäischen Parlaments und des Rates vom 21.04.2004 über Umwelthaftung zur Vermeidung und Sanierung von Umweltschäden (Umwelthaftungsrichtlinie) ist erstmals ein öffentlich-rechtliches Haftungssystem zum Ausgleich von Schäden an geschützten Arten und natürlichen Lebensräumen, Gewässern und Boden geschaffen worden... Unter Berücksichtigung der relevanten bestehenden Umwelthaftungsregelungen und des entsprechenden Versicherungsschutzes erfolgt zunächst anhand der Regelungen in der Umwelthaftungsrichtlinie eine Einschätzung dahingehend, ob diese Regelungen grundsätzlich eine Versicherbarkeit von Umweltschäden ermöglichen. Zudem wird der Frage nachgegangen, in welcher Form die bisherigen Versicherungen eventuell weiter bestehen oder einen Ansatz für neue Versicherungen bieten können. Die Arbeit richtet sich in erster Linie an Juristen und Wirtschaftswissenschaftler.
The increasing perils of connectivity technologies in the context of large satellite constellations come alongside with legal aspects concerning the protection of the space environment. The interplay of connectivity and sustainability must be regulated. To analyse the legal measures and tools regulating the risks, both sides of the problem are taken into consideration. The technological side of large satellite constellations is summarized under the term cybersecurity. Cyber is a code-based system, i.e. at first sight it requires a specialized field of law. This holds true on space sustainability as well. Large satellite constellations raise the discussion on space debris and junk. The consensus on the LTS guidelines by COPUOS at UNISPACE+50 in 2018 constitutes a milestone in Space Law. Space sustainability requires a particular adoption of legal norms: the idea is very similar to the subject of cybersecurity. Since both areas of issue are internationally driven and have multilateral impact, self-regulation proves ineffective. The genesis of reliable and uniform legal rules requires a different approach considering the multilevel systems of obligations with different binding authority. This thesis evaluates the balance between the future of connectivity and space sustainability in the context of large satellite constellations by considering the impact of legal rules with different binding authority.
