Die vorliegende Dissertation besteht aus fünf unabhängigen Forschungspapieren über optimale Steuer- und Bildungspolitik, welche ich während meines Promotionsstudiums an der Universität Konstanz erstellt habe. Private Versicherungen gegen Einkommensrisiko können aufgrund von moral hazard...

We introduce learning in a Brock-Mirman environment and study the effect of risk generated by the planner's econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty from the anticipation...

Exact optimal paths are calculated for two closed, continuous-time economies with explicit functional forms for utility from consumption, and for production from human-made capital and a non-renewable resource. Features of the first economy are non-linear utility, hyperbolic utility discounting...

The current commodity boom is a major opportunity for poor countries exportingexhaustible resources such as oil. In the past oil booms were often mismanaged leaving the country with lower long run income. Many countries are now well aware that booms require intricate savings and investment...

We analyze a multi-sector growth model with directed technical change where man-made capital and exhaustible resources are essential for production. The relative profitability of factor-specific innovations endogenously determines whether technical progress will be capital- or...

This paper examines the problem of optimal tax mix analytically in a two-sector growth model with transitional dynamics. Tax revenue is required to provide a pure public good. The key problems are: over-consumption of leisure under labor income or consumption taxes; and under-investment in human...
