How do we pursue labormetrics? An application using the MCVL

The objective of this paper is to describe a process through which the original information of an administrative data source (the Spanish Continuous Work History Sample) can be organised in such a way as to permit the accurate study of work histories. It presents a comparison of the information obtained using the procedure we propose (panel data file 2004-2009) and that obtained using retrospectively only one sample (2009 data file) in three empirical applications whose aim is to demonstrate the sample loss and bias which occurs when data regarding the spells and individuals figuring in the database are not processed correctly.
