Rights to territory and rights to immigration are usefully theorized together. Our starting point is a Lockean analysis of the moral foundations of territoriality offered by John Simmons. Crucially, this Lockean account makes the legitimacy of a state’s claim to its territory dependent on a...

Much current thinking about justice concerns the place of responsibility within an overall account of justice. Theorists of justice such as John Rawls have been criticized for their inability to make their conclusions accord with our intuitions about responsibility. This paper argues that such...

To what extent is a country allowed to regulate immigration into its territory, and thus to determine who lives there? Acts of immigration amount to changes in two distinct relationships. They amount to a change in political relationships, since the immigrant alters her political standing within...

We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities may vary. If they analyze the same situation...

Left-libertarian theories of justice hold that agents are full self-owners and that natural resources are owned in some egalitarian manner. Some philosophers find left-libertarianism promising because it seems that it coherently underwrites both some demands of material equality and some limits...

The two traditional ways of thinking about justice at the global level either limit the applicability of justice to states or else extend it to all human beings. The view I defend rejects both these approaches and instead recognizes different considerations or conditions based on which...

Standard economic theory teaches that trade benefits all countries involved, at least in the long run. While there are other reasons for trade liberalization, this insight, going back to Ricardo's 1817 Principles of Political Economy , continues to underlie international economics. Trade also...

Increasing political and economic interconnectedness draws much philosophical attention to the question of the conditions under which such stringent claims arise. Do claims of justice arise only among those who share membership in a state? Alternatively, do they arise among all those who are...

This paper develops and defends the approach to distributive justice the author presents in his 2012 book On Global Justice. Characteristic of that approach is that the notion of distributive justice is understood as capturing the most stringent moral demands while at the same time being broadly...
