Optimum commodity taxation theory asks how to raise a given amount of tax revenue while minimizing distortions. We reexamine Ramsey's inverse elasticity rule in presence of Hotelling-type non-renewable natural resources. Under standard assumptions borrowed from the...

Does a country strictly gain if it acts as a leader in a resource market under bilateral monopoly? Using differential games, we show that the answer is "yes"" when leadership can be exercised globally (global Stackelberg leadership), but possibly ""no"" when it is exercised only at each stage...

Constructing a dynamic game model of trade of an exhaustible resource, this paper compares feedback Nash and Stackelberg equilibria when the exporting country sets quantity rather than price. We consider two different leadership scenarios: leadership by the importing country, and leadership by...

Afforestation is a cost-effective way for some countries to meet part of their commitments under the Kyoto Protocol and its eventual extensions. Credits for carbon sequestration can be mediated through markets for emissions permits. Both new and old forests are subject to pestilence and fire,...

It is possible to make a current valuation of the effects of carbon dioxide which tracks a valuation done under the metric of expected present value and also tracks realized values. The implementation of a carbon credit scheme based on green accounting could go as follows: L'évaluation des...

There exists no formal treatment of non-renewable resource (NRR) supply, systematically deriving quantity as function of price. We establish instantaneous restricted (fixed reserves) and unrestricted NRR supply functions. The supply of a NRR at any date and location not only depends on the local...

This study compares Quebec's tax effort with that of the other Canadian provinces. The results show that the tax effort is higher in Quebec than in any other Canadian province. In the first section, the authors expose the global situation that currently prevails in Quebec. In the second section,...

This paper examines the impact of the Dutch R&D fiscal incentive program, known as WBSO, on R&D capital formation. Taking a factor-demand approach we measure the elasticity of firm R&D capital accumulation to its user cost. An econometric model is estimated using a rich unbalanced panel covering...

This paper looks at the effectiveness of R&D grants for Canadian plants that already benefit from R&D tax credits. Using a non-parametric matching estimator, we find that firms that benefited from both policy measures introduced more new products than their counterparts that only benefited from...
