A small open economy produces a consumer good along with green and black energy and imports fossil fuel for black-energy production at an uncertain world market price. Efficient risk management requires curbing fuel consumption, and hence carbon emissions, when consumers are prudent. Moreover,...

A small open economy produces a consumer good, green and black energy, and imports fossil fuel at an uncertain price. Unregulated competitive markets are shown to be inefficient. The implied market failures are due to the agents' attitudes toward risk, to risk shifting and the uniform price for...

Tradable White Certificates (TWC) schemes, also labelled Energy-Efficiency Certificates schemes, were recently implemented in Great Britain, Italy and France. Energy suppliers have to fund a given quantity of energy efficiency measures, or to buy so-called "white certificates" from other...

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...

Green technological progress bears a strong potential to alleviate climate change, but its utilization is contingent on factors which are by nature impossible to anticipate or predict. Developing stochastic optimisation models, we explore how the decision to invest in research and development...

Taxing internationally mobile factors of production has been dismissed as an inefficient means of raising tax revenue. This paper addresses the question of whether it is efficient to tax capital at source when labor markets and the taxation of lumpsum income suffer from imperfections. Four...

The purpose of this paper is to extend the dynamic resource allocation problem by including stock externalities like accumulated CO2 and SO2 emissions as well as flow externalities like waste of energy or pollutants which can be abated (SO2). The objective is to examine how the evolution of...
