In this paper, we discuss how register data can contribute to scientific progress within the field of empirical labour market economics. The discussion is founded on our own experience derived from the Norwegian Frisch Centre Database. We argue that access to register data opens up new and challenging avenues for future research, particularly with respect to the identification and estimation of causal effects. Efficient utilisation of register data requires development of new methodological approaches and new statistical and computational techniques. - Reproduced.  aPublic administration  aRaaum, Oddbjorn  aEconomic Journal
