In a standard partial equilibrium model of resource depletion, this paper charac- terizes and examines the solution to the optimal taxation problem when extraction is monopolistic. The main result is that the family of subgame perfect effciency- inducing tax/subsidy schemes may include some...

Optimal climate policy is studied in a Ramsey growth model with exhaustible oil reserves, an infinitelyelastic supply of renewables, stock-dependent oil extraction costs and convex climate damages. Weconcentrate on economies with an initial capital stock below that of the steady state of the...

Fossil fuels are non-renewable carbon resources, and the extraction path of these resources depends both on present and future demand. When this Hotelling feature is taken into consideration, the whole price path of carbon fuel will shift downwards as a response to the reduced cost of the...

Fossil fuels are non-renewable carbon resources, and the extraction path of these resources depends both on present and future demand. When this 'Hotelling feature' is taken into consideration, the whole price path of carbon fuel will shift downwards as a response to the reduced cost of the...

We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

Unter heutigen Rahmenbedingungen muss davon ausgegangen werden, dass der globale Primärenergieverbrauch sich bis 2050 mehr als verdoppeln wird und die energiebedingten CO2-Emissionen sogar um 137% steigen. Die Abhängigkeit der OECD-Staaten von Energieimporten würde weiter wachsen und der...

The demographic transition is introduced into the otherwise standard Ramsey model to generate multiple equilibria, poverty traps, and demography-driven cycles. The model is calibrated for global data to explore the demographic conditions under which multiplicity is realized. Three cases arise,...

The interaction between habit formation and pollution-type ex- ternalities modifies the social optimum through discount effects and elasticity effects. If the substitution elasticity does not exceed unity, both effects reduce optimal consumption and capital in the long run, and the optimal...

The purpose of this paper is to introduce a modification of a standard four input production process where energy is used in an inefficient way due to partly unnecessary waste of energy. In this production process, R&D investment is an additional input in order to improve energy efficiency. It...

We analyse optimal environmental policies in a market that is vertically differentiated in terms of the energy efficiency of products. Considering energy taxes, subsidies to firms for investment in more eco-friendly products, and product standards, we are particularly interested in how...
