Machine learning and the measurement of injustice

Daniel Mahler's picture

Machine learning methods are increasingly applied in the development policy arena. Among many recent policy applications, machine learning has been used to predict poverty, soil properties, and conflicts.

In a recent Policy Research Working Paper by Paolo Brunori, Paul Hufe and Daniel Mahler (BHM hereafter), machine learning methods are utilized to measure a popular understanding of distributional injustice – the amount of unequal opportunities individuals face. Equality of opportunity is an influential political ideal since it combines two powerful principles: individual responsibility and equality. In a world with equal opportunities, all individuals have the same chances to attain social positions and valuable outcomes. They are free to choose how to behave and they are held responsible for the consequences of their choices.

Migration: The future depends on our actions today

Around 250 million migrants currently live outside their countries of birth, making up approximately 3.5 percent of the world population. Despite the widespread perception of a global migration crisis, this ratio has stayed remarkably stable since the end of the Second World War and lags well behind other major metrics of globalization – international trade, capital flows, tourism etc. A more remarkable statistic is that refugees, at around 15 million, account for 6 percent of the migrant population and only 0.2 percent of world population. In other words, we can fit all refugees in the world in a city with an area of 5000 square kilometers – roughly the size of metropolitan Istanbul or London or Paris – and still have some space left over.

Equality of opportunity for what?

Equality of opportunity is a popular policy objective around the world. It is deeply embodied in the American Dream and has resonated with politicians ranging from Margaret Thatcher to Nelson Mandela. It is also connected to the World Bank’s goal of shared prosperity; individuals with low opportunities should have a chance of growing and prospering in life.
