In this book Edward and Sumner argue that to better understand the impact of global growth on poverty it is necessary to consider what happens across a wide range of poverty lines. Starting with the same datasets used to produce official estimates of global poverty, they create a model of global consumption that spans the entire world’s population. They go on to demonstrate how their model can be utilised to understand how different poverty lines imply very different visions of how the global economy needs to work in order for poverty to be eradicated.
