This paper makes some steps toward a formal political economy of environmental policy. Economists' quasi-unanimous preferences for sophisticated incentive regulation is reconsidered. First, we recast the question of instrument choice in the general mechanism literature and provide an incomplete contract approach to political economy. Then, in various settings, we show why constitutional constraints on the instruments of environmental policy may be desirable, even though they appear inefficient from a purely standard economic viewpoint.

Recent empirical evidence from vector autoregressions (VARs) suggests that public spending shocks increase (crowd in) private consumption. Standard general equilibrium models predict the opposite. We show that a standard real business cycle (RBC) model in which public spending is chosen optimally can rationalize the crowding-in effect documented in the VAR literature. When such a model is used as a data-generating process, a VAR estimated using the artificial data yields a positive consumption response to an increase in public spending, consistent with the empirical findings. This result holds regardless of whether private and public purchases are complements or substitutes.

I argue that it is time for many feminists to rethink their attitudes towards evolutionary biology, not because feminists have been wrong to be deeply sceptical about many of its claims, both explicit and implicit, but because biology itself has changed. A new appreciation for the importance of development in biology has become mainstream and a new ontology, associated with developmental systems theory (DST), has been introduced over the last two decades. This turn challenges some of the features of evolutionary biology that have most troubled feminists. DST undermines the idea of biologicales sence and challenges both nature /nurture and nature/culture distinctions. Freed from these conceptual constraints, evolutionary biology no longer poses the problems that have justified feminist scepticism. Indeed, feminists have already found useful applications for DST and I argue that they should expand their use of DST to support more radical and wide-ranging political theories.

La présente étude se concentre sur le travail de Nancy Fraser sur la justice sociale, lequel a suscité beaucoup d’intérêt dans la littérature au cours des dernières années. La reconnaissance et la redistribution sont les deux piliers originaux de son approche: les désavantages dont souffrent les gens dus au dénigrement culturel ou à la privation économique. Ces deux concepts servent à diagnostiquer et fournir le soutien moral aux multiples luttes que les victimes d’injustice entreprennent avec l’objectif d’établir une participation plus égalitaire à la société. Cependant, que peut-elle dire cette approche des groupes qui sont marginalisés et cherchent l’autogouvernance (ou la séparation même) plutôt que l’intégration dans la société? Le travail de Fraser manifeste une résistance envers les droits du groupe, et un silence quant à l’autodétermination. Mon intervention prend comme objectif d’inclure ces formes d’injustice dans son approche, la rendant plus sensible aux dynamiques des groupes et capable de répondre à leurs revendications trop souvent négligées sous prétexte de l’égalité. La question est, l’égalité de qui?

La théorie de la guerre juste a fournit les principes qui forment la base de nos intuitions concernant l’éthique de la guerre pendant plus de milles ans. Cependant, la nature de la guerre a changé drastiquement dans les derniers 50 ans. Avec les avancés technologiques, tous les aspects de la guerre, du champ de bataille aux armes utilisées, sont aujourd’hui très différents. Ce qui est proposé dans ce texte est que les principes de jus in bello sont malgré tout encore adéquats pour les guerres contemporaines. Spécifiquement, en utilisant une analyse historique, ce texte argumentera contre la condition de l’urgence suprême de Michael Walzer pour proposer une approche qui laisse les principes de bases du jus in bello intactes. Ce texte suggère que les théoriciens de la guerre juste se penchent sur la question des armes prohibées pour avoir un impacte positif dans le domaine de l’éthique de la guerre.

To be a coherent and genuinely alternative conception to the shareholder model, any moral stakeholder theory must meet the following conditions: (1) It must be an ethical theory; (2) It must identify a limited group as stakeholders; (3) The group must be identified on morally relevant grounds; (4) Stakeholder claims must be non-universal; (5) And not held against everyone. A principle for identifying the stakeholder is suggested as a person who has much to lose – financially, socially, or psychologically – by the failure of the firm. The emerging picture contrasts sharply with the conventional conception of the firm.

Roughly speaking, Enron has done for reflection on corporate governance what AIDS did for research on the immune system. So far, however, virtually all of this reflection on and subsequent reform of governance has come from those with a stake in the success of modern capitalism. This paper identifies a number of governance challenges for critics of capitalism, and in particular for those who urge corporations to voluntarily adopt missions of broader social responsibility and equal treatment for all stakeholder groups. I argue that by generally neglecting the governance relation between shareholders and senior managers, stakeholder theorists have underestimated the way in which shareholder-focused governance can be in the interests of all stakeholder groups. The enemy, if you will, is not capitalists (shareholders), but greedy, corrupt or incompetent managers. A second set of governance challenges for stakeholder theorists concerns their largely untested proposals for governance reforms that would require managers to act in the interests of all stakeholders and not just shareholders; in other words to treat shareholders as just another stakeholder group. I suggest that in such a governance regime it may be almost impossible to hold managers accountable to anyone – just as it was when state-owned enterprises were given “multi-stakeholder” mandates in the 1960s and 1970s.

Philippe van Parijs (2003) has argued that an egalitarian ethos cannot be part of a post- Political Liberalism Rawlsian view of justice, because the demands of political justice are confined to principles for institutions of the basic structure alone. This paper argues, by contrast, that certain principles for individual conduct—including a principle requiring relatively advantaged individuals to sometimes make their economic choices with the aim of maximising the prospects of the least advantaged—are an integral part of a Rawlsian political conception of justice. It concludes that incentive payments will have a clearly limited role in a Rawlsian theory of justice.
