  Philosophers have been concerned with answers to a range of questions such as: What kinds of economic arrangements are just?  Should our international institutions be reformed to better reflect fair terms of co-operation in our globalized world? Can globalization be better managed so that it works to assist the global poor more effectively? Are protectionist policies in trade justified or, rather, is free trade required by considerations of justice? Should poor working conditions in developing countries be a matter of concern for citizens and consumers in affluent, developed countries? If so, how might harmful employment conditions be effectively improved?
