Rojas was lecturer at Lund University from 1981 to 1999, when he became the Director of the Centre for Welfare Reform at the Stockholm-based think tank Timbro.

He has written several books in the field of international economics, immigration matters and on the Swedish model, many of them translated into several languages.
