Abstract
This paper demonstrates how firm information can be extracted from administrative
social security records. We use the Austrian Social Security Database (ASSD) and derive
firms from employer identifiers in the univers
e of private sector workers. To correctly pin
down entry end exits we use a worker flow approach which follows clusters of workers as
they move across administrative entities. This procedure enables us to define different
types of entry and exit such as start-ups, spinoffs, closures, or take-overs. We show that
our firm definition results in a demography which is comparable to official statistics of
firm registers. The resulting database, covering the period of 1976 to 2006, is a valuable
resource for future research on industry evolution in Austria.
