The modern literature on responding to global poverty is over fifty years old and has attracted the attention of some of the most prominent analytical political theorists of the age, including Brian Barry, Charles Beitz, Simon Caney, Thomas Pogge, John Rawls, and Peter Singer. Yet in spite of this extraordinary concentration of brainpower, the problem of global poverty has quite clearly not been solved or, indeed, adequately defined. We are therefore entitled to ask two questions of any new contribution to this literature: first, what does it have to offer that past work does not; and second, what reason is there to think that, this time, it will truly make a difference. These questions will be posed below, but before undertaking this task it may be useful to offer an overview of the field, with particular attention to why the problem of global poverty seems so intractable.
