A framing effect occurs when an agent's choices are not invariant under changes in the way a decision problem is presented, e.g. changes in the way options are described (violation of description invariance) or preferences are elicited (violation of procedure invariance). Here we identify those rationality violations that underlie framing effects. We attribute to the agent a sequential decision process in which a “target” proposition and several “background” propositions are considered. We suggest that the agent exhibits a framing effect if and only if two conditions are met. First, different presentations of the decision problem lead the agent to consider the propositions in a different order (the empirical condition). Second, different such “decision paths” lead to different decisions on the target proposition (the logical condition). The second condition holds when the agent's initial dispositions on the propositions are “implicitly inconsistent,” which may be caused by violations of “deductive closure.” Our account is consistent with some observations made by psychologists and provides a unified framework for explaining violations of description and procedure invariance.

What should maximin egalitarians think about seniority privileges? We contrast a good-specific and an all-things-considered perspective. As to the former, inertia and erasing effects of a seniority-based allocation of benefits from employment are identified, allowing us to spot the categories of workers and job-seekers made involuntarily worse off by such a practice. What matters however is to find out whether abolishing seniority privileges will bring about a society in which the all-things-considered worst off people are better off than in the seniority rule's presence. An assessment of the latter's cost-reduction potential is thus needed, enabling us to bridge a practice taking place within a firm with its impact on who the least well off members of society are likely to be. Three accounts of the profitability of seniority privileges are discussed: the “(firm specific) human capital”, the “deferred compensation” and the “knowledge transfer” ones. The respective relevance of “good-specific” and “all-things-considered” analysis is discussed. It turns out that under certain circumstances, a maximin egalitarian case for seniority privileges could be made.

Senior: Do you know that they are planning layoffs? Of course, it is only fair that they lay-off the newcomers first! After all, I have been loyal to the company for many years.

Junior: Did I choose to be a newcomer?

We address the question of how finitely additive moral value theories (such as utilitarianism) should rank worlds when there are an infinite number of locations of value (people, times, etc.). In the finite case, finitely additive theories satisfy both Weak Pareto and a strong anonymity condition. In the infinite case, however, these two conditions are incompatible, and thus a question arises as to which of these two conditions should be rejected. In a recent contribution, Hamkins and Montero (2000) have argued in favor of an anonymity-like isomorphism principle and against Weak Pareto. After casting doubt on their criticism of Weak Pareto, we show how it, in combination with certain other plausible principles, generates a plausible and fairly strong principle for the infinite case. We further show that where locations are the same in all worlds, but have no natural order, this principle turns out to be equivalent to a strengthening of a principle defended by Vallentyne and Kagan (1997), and also to a weakened version of the catching-up criterion developed by Atsumi (1965) and by von Weizsäcker (1965).

David Hume's sympathetic principle applies to physical equals. In his account, we sympathize with those like us. By contrast, Adam Smith's sympathetic principle induces equality. We consider Hume's “other rational species” problem to see whether Smith's wider sympathetic principle would alter Hume's conclusion that “superior” beings will enslave “inferior” beings. We show that Smith introduces the notion of “generosity,” which functions as if it were Hume's justice even when there is no possibility of contract.

This paper develops a normative evaluation of the minimum wage in the light of recent evidence and theory about its effects. It argues that the minimum wage should be evaluated using a consequentialist criterion that gives priority to the jobs and incomes of the worst off. This criterion would be accepted by many different types of consequentialism, especially given the two major views about what the minimum wage does. One is that the minimum wage harms the jobs and incomes of the worst off and the other is that it does neither much harm nor much good. The paper then argues at length that there are no important considerations besides jobs and incomes relevant to the assessment of the minimum wage. It criticizes exploitation arguments for the minimum wage. It is not clear that the minimum wage would reduce exploitation and the paper doubts that, if it did, it would do so in a morally significant way. The paper then criticizes freedom arguments against the minimum wage by rejecting appeals to self-ownership and freedom of contract and by arguing that no freedom of significance is lost by the minimum wage that is not already taken account of in the main consequentialist criterion. The conclusion is that, at worst, the minimum wage is a mistake and, at best, something to be half-hearted about.
