'Time is the ultimate scarce resource, defying every human attempt to defy its inevitable reckoning. As a result, time is intimately bound up with struggles over power and resources; indeed it often gives those struggles their meaning and point. Yet political theorists have paid scant attention to time. Elizabeth F. Cohen sets out to remedy this situation in her lucid and engaging new book. She develops a political economy of time and exhibits its implications for a host of debates about rights, power, and distribution. This is an important and novel contribution.'
