ABSTRACT
The ethical perspectives represented in this volume rest on different premises, yet the contributors often reach surprisingly similar conclusions. Most defend some kind of compromise between the opposing values of free movement and free association, between free markets and the regu lation of economic activity for the common good. Even those who argue that borders should be open to the free movement of people and money, as a matter of principle, are prepared to accept restrictions on free movement under certain conditions. And this suggests that there is no absolute right to travel or reside, or to buy or sell, wherever one pleases. There may be a presumption in favour of unlimited freedom, but this presumption can be challenged on a variety of grounds.
