Social Opportunities and Individual Responsibility: The Capability Approach and the Third Way

The fashionable widespreading of Sen’s ideas coincides with a new mood in the shaping of public policies in affluent societies. In Europe indeed, an “opportunity”-based approach to social security has been implemented through the European Employment Strategy. Public action tends to rely on a procedural concern with individual opportunities or potentialities in the labour market. The underlying ethics is that individuals are then responsible to use these background opportunities in order to lead the kind of life they value most. More broadly, the discourse and practice of the so-called “Third Way” shares with the capability approach an appeal for a procedural and enabling depiction of the role of the State. The paper intends to clarify the relation between procedural and opportunity-based approaches to social justice, among them the capability approach, and these new patterns of public action. Our vision goes in the way of a yet renewed, but deeper action of the welfare state, where social agency is envisaged as the very condition of individual agency. Drawing on the various critics of mainstream equality of opportunity, two opposed approaches to responsibility are identified: on the one hand, responsibility is conceived of as i) a “luck vs. choice” fixed starting point, ii) a backward-looking conception and iii) a highly individualistic framework. On the other hand, responsibility is envisaged as i) an outcome of public policies rather than a starting point, ii) a forward-looking conception, and iii) a combined institutional-individual framework. We situate here Sen’s capability approach, as well as critics of the luck egalitarianism path. The Third Way rhetoric is assessed against both these perspectives. The issue eventually boils down to an ethical reflection on the articulation of responsibilities, and to a pragmatic and substantial concern for the content of what providing security should mean in practice.

Prices of durable nonrenewable natural resources under stochastic investment opportunities

On étudie l'évolution du prix d'une ressource naturelle non renouvelable dans le cas où cette ressource est durable, c'est-à-dire qu'une fois extraite elle devient un actif productif détenu hors terre. On emprunte à la théorie de la détermination du prix des actifs pour ce faire. Le choix de portefeuille porte alors sur les actifs suivant : un stock de ressource non renouvelable détenu en terre, qui ne procure aucun service productif; un stock de ressource détenu hors terre, qui procure un flux de services productifs; un stock d'un bien composite, qui peut être détenu soit sous forme de capital productif, soit sous forme d'une obligation dont le rendement est donn e. Les productivités du secteur de production du bien composite et du secteur de l'extraction de la ressource évoluent de façon stochastique. On montre que la prédiction que l'on peut tirer quant au sentier de prix de la ressource diffère considérablement de celle qui découle de la règle d'Hotelling élémentaire et qu'aucune prédiction non ambiguë quant au comportement du sentier de prix ne peut être obtenue de façon analytique.

Algal Biofuels: Challenges and Opportunities

Biodiesel production using microalgae is attractive in a number of respects. Here a number of pros and cons to using microalgae for biofuels production are reviewed. Algal cultivation can be carried out using non-arable land and non-potable water with simple nutrient supply. In addition, algal biomass productivities are much higher than those of vascular plants and the extractable content of lipids that can be usefully converted to biodiesel, triacylglycerols (TAGs) can be much higher than that of the oil seeds now used for first generation biodiesel. On the other hand, practical, cost-effective production of biofuels from microalgae requires that a number of obstacles be overcome. These include the development of low-cost, effective growth systems, efficient and energy saving harvesting techniques, and methods for oil extraction and conversion that are environmentally benign and cost-effective. Promising recent advances in these areas are highlighted.
