Migration of sub-Saharan Africans is growing rapidly. Just like the region’s population, the number of migrants doubled since 1990 to reach about 20 million in 2013.

We studied these trends in a recent paper because both receiving and sending countries need the right policies so all can benefit.

Indiana Jones, the fictional character of the namesake movies, once said “It’s not the years, it’s the mileage.” The quote comes to mind as many advanced economies wrestle with the best way for pension reform to ensure both retirees and governments don’t go broke.

Our analysis shows that gradually raising retirement ages could help countries contain pension spending increases and boost economic growth.
